Blog 1. Let’s Get Sustainable: Setbacks & Solutions
On January 23, 2020, the Trump administration approved a policy change that ends federal protection for much of the U.S.’s streams, arroyos, and wetlands, leaving them subject to the harmful pollution caused by development, industry, and farms. This comes unsurprisingly with Trump’s record of caring more for business than environmental degradation and sustainability.
The importance of sustainability is better understood when we understand the three scientific principles of sustainability: dependence on solar energy, biodiversity, and chemical cycling.
Figure 1. The Three Scientific Principles of Sustainability (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018.)
These three principles are not only what makes Earth so unique, but also what has kept Earth alive for billions of years. Solar energy warms the planet and provides energy. Energy that is transformed into nutrients by plants. Biodiversity is used to describe the wide variety of genes, species, ecosystems, and ecosystem processes that keep our world in check. Chemical cycling describes how organisms recycle chemicals in order to keep the nonrenewable resource around. In nature, waste is a useful resource. In addition, there are three main categories of natural resources. Those that are inexhaustible will always be available to us, such as solar energy. Those that are renewable are able to replenish themselves within a certain time frame, so as long as we don’t use it faster than it can replace itself, it will be available to us. However, those that exist only in a finite manner we call nonrenewable or exhaustible. These include oil, coal, natural gas, copper, salt, and sand. Scientists work tirelessly to create replacements for these resources as we continue to deplete them. In the chemistry research lab I am a part of we are searching for ways to use nanomaterials in renewable energy devices solar cells, fuel cells, and photocatalysts in hopes that they will replace fossil fuels.
Figure 2. Three Types of Natural Resources (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018.)
A major issue that we currently face is the degradation of natural capital. We, humans, are wreaking havoc on earth’s natural capital with pollution and waste. When we create pollution and waste at such a fast rate, the air, soil, and water are no longer able to cleanse themselves naturally. Also, much of our waste is composed of synthetic materials that disrupt these natural cycles and processes. Perhaps now it is easier to understand why the Trump Administration’s decision to end federal protection of many streams, arroyos, and wetlands, subjecting them to pollution and waste from businesses and farms, is so harmful.
The harmful impact we have on the environment has been termed our ecological footprint. If our ecological footprint is larger than the biocapacity of our area, we have an ecological deficit. In completing a personal ecological footprint quiz, which can be found at https://www.footprintcalculator.org/, I discovered that if everyone lived like I do while a student at Fordham, we would need 3.2 Earths to sustain us. Even more shocking, my Earth overshoot day is April 24, not even halfway through the year. This was a disturbing personal discovery, and I find myself confused and angered by how unsustainably I am living. When comparing the ecological footprints of countries, I found the countries with the largest deficits to be the United Arab Emirates, Israel, the U.S., and Japan, while the countries with ecological credits were Australia, Brazil, Canada, Russia, and China. I am not surprised that the countries with ecological deficits are largely affluent countries, but also those with ecological credits tend to be affluent, with large land masses.
Figure 3. Ecological Footprints (“What is an Ecological Footprint?” Earth Overshoot Day. Accessed January, 2020. https://www.overshootday.org/kids-and-teachers-corner/what-is-an-ecological-footprint/)
The growing urgency of this issue has led to people of all academic dispositions to seek solutions. Full-cost pricing, from economists, suggests that market prices include the environmental and health costs of their products. Win-win solutions, from politicians, suggests that solutions to these issues should seek to benefit the majority of people as well as the environment. Ethicists stress our responsibility to future generations, claiming it would be wrong to leave the planet in distress after our own lifetimes.
The fact of the matter is that we are currently living unsustainably. In a 2005 report by the UN, it was stated that “human activities have overused about 60% of the ecosystem services provided by nature, mostly since 1950” [1]. In the 1992 World Scientists’ Warning to Humanity, damage to the atmosphere, water resources, oceans, soil, forests, and living species was described as “irreversible on a scale of centuries, or permanent” [2]. They emphasized the finite nature of nature, and issued five calls to action: to control environmentally damaging activities, manage resources better, stabilize the population, reduce and eliminate poverty, and achieve sexual equality.
In the more recent World Scientists’ Warning of a Climate Emergency, released just three months ago in November 2019, scientists emphasized their moral obligation to warn the rest of humanity about the danger we are putting our planet in. They suggest critical steps we must take in order to change the trajectory we have set for ourselves and our home. First, we must quickly implement energy efficiency and conservation practices. Second, we need to decrease emissions of short-lived pollutants. Third, we must protect and restore Earth’s ecosystems. Fourth, we ought to eat mostly plant-based foods in order to reduce GHG emissions and improve human health, and reduce the amount of food waste. Fifth, we must stop putting economic growth over the health of our planet by shifting our goals away from affluence and toward sustaining ecosystems. Finally, we must stabilize the world population. In all of these steps, developed, affluent nations must lead and assist poorer, less-developed nations achieve the goals.
While affluent nations are often more educated about environmental issues, affluence is directly linked to environmental degradation because as total resource consumption and average consumption per person increase, so does waste, pollution, and our environmental footprints. Another economic aspect of environmental issues is the fact that most companies do not pay for the harmful effects that they have on the environment. In fact, governments often give companies subsidies (tax breaks, payments, and other benefits) that help them economically, but only further environmental degradation.
All of this sounds startling, right? If scientists have been issuing warnings about the future of our planet for over 20 years, why hasn’t there been a drastic change? Things get complicated when we consider the different environmental worldviews people hold. While I may read all of the statistics and warnings and feel angry, frustrated, and encouraged to make a change, others don’t see it the same. Some have a more human-centered view, in which humans and nature are separate, and nature exists to serve and sustain us. Others have a life-centered view, in which all species are valued and therefore we should avoid activities that would lead to the extinction of other species. Those with an earth-centered view see humans as a part of nature, and believe that natural capital is not just for humans. This view emphasizes biomimicry, the idea that we should learn from and imitate nature.
Figure 4. The 2017 Peoples’ Climate March. (Spanger-Siegfried. “What’s Next After the Peoples Climate March? Riding the Momentum and Bringing it Home.” Union of Concerned Scientists. May 2, 2017. Accessed January 2020. https://blog.ucsusa.org/erika-spanger-siegfried/whats-next-after-the-peoples-climate-march-riding-the-momentum-and-bringing-it-home)
I believe that regardless of our differences in worldviews, all people should be able to recognize that our current degradation of the planet is unethical, and we must take immediate action. It can be easy to feel hopeless, but it is more important to know that research shows only 5-10% of the population of a community is required to make serious change, and that it can happen faster than we think. All it takes is for a group of engaged citizens to stand up and demand change, and eventually our voices will be loud enough they can’t be ignored.

Blog 2. Let’s Get Scientific: Ecosystems & Biodiversity
Environmental studies cannot be discussed without mention of science. Natural sciences and the scientists that study them are fundamental to understanding how our environment works, how we come to understand the way it works, and how we are affecting it.
In chapters 2 and 3 of Living in the Environment, Miller covers the basics of natural sciences like chemistry, biology, and physics, as they apply to environmental studies. As a chemistry major, most of the information was review, but in order to have a comprehensive understanding of environmental studies the information is critical. Scientists study the natural world through field and laboratory research. Field research allows first-hand observation of forests, oceans, and mountains, examining the extremely complex ecosystems that exist and collecting data that aids humans in interacting with said ecosystems. Laboratory research involves the development of systems that mimic natural ones, and are helpful because they allow for better control of variables.
Some scientific principles, like the law of conservation of energy, help describe why some human behaviors are so harmful to the environment. Energy is divided into two categories: renewable and nonrenewable. Renewable sources of energy, like solar power, wind, moving water, wind, and geothermal energy are replenishable through natural processes. Nonrenewable sources of energy are not replenishable through natural processes on a human time scale, these include oil, coal, natural gas, and nuclear energy. Commercial energy is the 1% of energy that does not come from the sun. The burning of fossil fuels makes up 90% of it.
There are four main systems of earth’s life support system: the atmosphere, hydrosphere, geosphere, and biosphere. The atmosphere contains ozone that filters out 95% of UV radiation, and other gasses that help keep the earth warm by trapping heat from the sun. Oceans contain 97% of earth’s water and an enormous amount of biodiversity. The geosphere contains fossil fuels and minerals that are used by humans and other species regularly. Finally, the biosphere is where we live, along with all other life forms.
An important part of the way the world operates is how organisms interact with each other. Organisms are either producers (who make their own nutrients from the environment), consumers (who feed on other organisms for nutrients), or decomposers (who transform waste into nutrients). Ecosystems are sustained through the one-way energy flow (solar energy) and nutrient cycling that happens through these three groups of organisms. Two key indicators are GPP (gross primary productivity) and NPP (net primary productivity). GPP is the rate that energy is converted from solar to chemical by producers and stored in compounds, and NPP is the rate that producers use photosynthesis to produce chemical energy minus the rate they use the stored energy in aerobic respiration.
Figure 1. Indicators of productivity. (“How does gross primary productivity differ from net primary productivity?” Socratic Q&A Biology. November 3, 2015. Accessed February 2, 2020.https://socratic.org/questions/how-does-gross-primary-productivity-differ-from-net-primary-productivity)
There are numerous other natural cycles that sustain life on earth, including the water cycle, carbon cycle, nitrogen cycle, and phosphorous cycle. I find cycles to be best understood through diagrams, so below are some helpful graphics.

Chapter four examines the importance of biodiversity, “the variety of life on earth” [1]. There are four components to biodiversity, species diversity, genetic diversity, ecosystem diversity, and functional diversity. Species diversity deals not only with the number of different species in an ecosystem (richness) but also their comparative abundance (evenness). Genetic diversity is the variety of different genes in a species. Ecosystem diversity refers to the presence of many different biological communities, such as deserts, oceans, mountains, and forests. Functional diversity is the variety of natural processes within ecosystems.
Within an ecosystem, species play different roles, termed their “ecological niche,” which can be either broad (for generalists) or narrow (for specialists). Species are classified as native, nonnative, indicator, or keystone to an ecosystem. While definitions of native and nonnative are rather straightforward, indicator species warn of changes in environmental conditions, and keystone species are those that are fundamental to the ecosystem–without them, there is a great risk of collapse.
Earth’s biodiversity is ultimately determined by the balance between speciation (production of new species) and extinction which are entirely dependent on our changing environmental conditions.
Chapter five discusses how species interact, including predator-prey relationships, parasitism, mutualism, and commensalism, and how populations work, examining births, deaths, immigration, and emigration. A big idea communicated in the chapter is that “no population can escape natural limiting factors and grow indefinitely” [2], reminding us that humans are just as vulnerable as other species, especially considering the projected outcomes of our environmentally degrading behaviors.
Chapter seven studies how climate affects biodiversity. Climate, unlike weather, is the “general pattern of atmospheric conditions in a given area” [3] over a long period of time. Differences in climate have a great impact on the types and locations of deserts, grasslands, forests, and mountains. After going through all the world’s major terrestrial ecosystems, the book reveals that humans are degrading about 60% of them.
Figure 6. The major impacts that humans have on terrestrial ecosystems (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018.)
Chapter eight dives into the subject of aquatic biodiversity, specifically why marine ecosystems are so important. They provide a number of ecosystem and economic services, such as production of oxygen, water purification, nutrient cycling, food, energy, recreation, and employment. One very timely mention the book makes is the growing threat of ocean acidification. In my sophomore year of high school, I remember learning the chemical equation that represents this process. It was one of the first times I had seen an environmental issue represented so physically and plainly to my understanding. When carbon dioxide reacts with ocean water, carbonic acid is formed which is detrimental because it decreases the amount of carbonate ions available for the formation of coral reefs and the shells and skeletons of organisms.
Figure 7. The process of ocean acidification. (Rafferty, John P. “Ocean Acidification.” Encyclopedia Britannica. January 30, 2020. Accessed February 2, 2020. https://www.britannica.com/science/ocean-acidification)
Other major threats to aquatic biodiversity are coastal development, runoff of pollutants, overfishing, and invasive species. Freshwater systems are also incredibly important, providing many ecosystem and economic services similar to marine systems, but one major new service is the provision of drinking water, which is a huge issue, especially politically.
In order to sustain aquatic biodiversity, I believe we must control emissions of carbon dioxide to prevent further damage to coral reefs, reduce fishing subsidies, and pass more laws protecting aquatic environments, unlike the Trump administration’s action that I referenced last week that did the opposite.
While all of this information may appear overwhelming at first, it is absolutely critical to understand the cycles and relationships of the natural world in order to make significant environmental change. The interconnectedness of all living things is essential to making people care about things other than themselves. Although this may present a rather pessimistic view of humanity, people overwhelmingly care about things more when they realize that it will directly affect them in their own daily lives. Instead of thinking about the nitrogen cycle as some abstract elementary science lesson, it becomes a part of our own daily routine. Through this, a genuine care for the environment can be inspired.

Blog 3. Let’s Talk About History
In addition to looking at the science behind environmental studies, the discipline can also be looked at through the lens of a historian. Something that becomes very clear in researching environmental history is that there is no unified account of history, and that the differences arise from intentional or unintentional biases. While examining different accounts of history is insightful, it is generally unproductive to attempt to uncover the “true” history, as each account has facets of the truth. All history is riddled with subjectivity and therefore detailed analysis is the most helpful way to learn from history.
Big History, as termed by David Christian, “examines history from the Big Bang to the present” [1]. Unlike other history courses that begin with the beginning of farming/civilization, Big History looks much farther back (approximately 14 billion years ago), placing “human history in the wider context of the universe’s history” [2]. In particular, the discipline uses modern discoveries in fields like biology, chemistry, anthropology, physics, economics, among many others, to create a comprehensive story of the universe. Some of the methods used by Big Historians include radiocarbon dating, genetic analysis, and thermodynamics. While critics argue that the study is “anti-humanist” and overly-scientific, many find the subject enlightening. Christian divided big history into 6 threshold stages [3]:
1. The universe appears, incredibly hot, busting, expanding, within a second.
2. Stars are born.
3. Stars die, creating temperatures hot enough to make complex chemicals, as well as rocks, asteroids, planets, moons, and our solar system.
4. Earth is created.
5. Life appears on Earth, with molecules growing from the Goldilocks conditions, with neither too much nor too little energy.
6. Humans appear, language, collective learning.
Big History emphasizes the importance of the Goldilocks principle, which says that “"circumstances must be right for any type of complexity to form or continue to exist,“ [4] and suggests that humans have been affecting climate change, with the Industrial Revolution greatly increasing the scale of our effect. I think that the idea behind Big History is important, as it encourages a shift from humans to the universe as a whole, as the subject of history. Traditional history courses that teach only about humanity perpetuate the separation and isolation of humans from the rest of earth, consequently minimizing the value of animals, plants, and nature. It also lessens the divide between history and science, which is important in environmental studies.
Anthropocene is “a proposed geological epoch dating from the commencement of significant human impact on Earth’s geology and ecosystems” [5] such as anthropogenic climate change. Although not officially approved, the proposed epoch has many supporters. However, there is disagreement on what the start date of the epoch should be, some arguing that it should be the start of the Agricultural Revolution, others thinking it should be as recent as the 1960s. The most striking proposed start date is the date of the detonation of the first atomic bomb in 1945.
Figure 1. A timeline starting with the formation of Earth and ending with the Holocene. The proposed Anthropocene would come next. (Frank, Adam. “Climate Change and the Astrobiology of the Anthropocene.” WAMC. October 1, 2016. Accessed February 7, 2020. https://www.wamc.org/post/climate-change-and-astrobiology-anthropocene)
Homogenocene is a closely related epoch that describes the current decline of biodiversity and commonizing effect of invasive species on ecosystems. It is commonly believed that humankind has entered the Earth’s sixth major extinction, and are rapidly accelerating its rate (between 100 to 1000 times faster than extinction rates of the past). Some argue that without humans, Earth’s biodiversity would grow at an exponential rate. But as it is now, as much as 7% of all species may have disappeared already, along with 50% of animal individuals. The composition of Earth’s biomass is staggering: livestock makes up 60%, humans make up 36%, and wild mammals make up 4%.
Many species are moving into regions that used to be too cold for them, due to climate change, farming, fishing, and the spread of nonnative species because of global travel. Other animals are becoming nocturnal to avoid contact with humans. Human activity is also transforming Earth’s physical surface and drainage patterns, along with leaving many other types of records, including sedimentological records, fossil records, and trace elements from modern science.
The movie Journey of the Universe deals with history beginning with the creation of the universe up until today. An important mention of the film is that the evolution of the Earth has been taken over by symbolic consciousness, making it no longer simply biological. Human activity has such a great impact on Earth’s evolutionary dynamics that the process isn’t purely “natural” anymore. Therefore the story of history must include mention of how human behavior has impacted and continues to impact the Earth.
Collapse: How Societies Choose to Fail or Succeed is Jared Diamond’s 2005 book examining causes of historical or pre-historical societal collapses, which he defines as “"a drastic decrease in human population size and/or political/economic/social complexity, over a considerable area, for an extended time."” [6] Diamond focuses particularly on the effects of environmental changes and climate change, and how society has responded to them. Throughout the book, Diamond suggests that we currently face the same issues but on a larger scale, and there could be catastrophic consequences for us in the future.
One of the main lessons he draws from examining history is that the collapse of a society often happens perhaps a decade or two after its peak. “The reason is simple,” he explains “maximum population, wealth, resource consumption, and waste production mean maximum environmental impact, approaching the limit where impact outstrips resources.” [7] In terms of how we can change, Diamond proposes two things. First, we must focus on long-term planning in order to address issues before they even arise. Second, we must be willing to reconsider our core values. I agree with Diamond’s proposals. I think that a country like the United States, and its citizens, need to entirely shift their focus from economic growth and national prosperity to environmental awareness and natural prosperity. Our individualistic, capitalistic, and competitive tendencies are the root of our environmental havoc. If we adopt a more holistic view of Earth and all of its beings, humans as just one of many species, only then will true environmental change take place.
The environmental history of the United States can be split up into four major eras:
1.Tribal Era: characterized by Native American occupation of the U.S.
2.The Frontier Era (1607-1890): characterized by the settling of European colonists who saw the wilderness as something for human use
3. Early Conservationists (1832-1870): characterized by the realization of the scope of depletion and degradation, and the push for protected areas
4. Now (1870-present): characterized by an increased role of the federal government and private citizens in environmental issues
An interesting case study reveals how air pollution is not a modern development. Going as far back as the human discovery of fire, air pollution has been a consistent element of human existence. Dense wood smoke appeared over urban areas in Europe in the Middle Ages, the burning of coal plagued the atmosphere during the Industrial Revolution, and remains an issue today. Air pollution levels are greatly linked to public health issues, particularly respiratory illnesses like bronchitis.
Figure 2. The Contribution of Air Pollution Versus Other Risk Factors to Global Mortality. (Rajagopalan, Sanjay, Sadeer G. Al Kindi and Robert D. Brook. “Air Pollution and Cardiovascular Disease.” Journal of the American College of Cardiology. October 2018. Accessed February 7, 2020. http://www.onlinejacc.org/content/72/17/2054?fbclid=IwAR3BO5AL0JzZgFx5EOtXagmaBNMG_WXngrgKJC4zFEuAa9QLOUqwQG7YoUM)
In Stoll’s conclusion he mentions how “environmentalism has not figured prominently in any presidency since Richard Nixon’s” [8] It’s interesting to see how important environmental issues are in the current presidential election. Senator Bernie Sanders, who just won the Iowa Caucus popular vote, takes a strong stance in favor of a Green New Deal. While many other democratic candidates also feature environmentalism in their campaigns, the same cannot be said for President Trump, who is running for re-election as the republican candidate.

Accessed February 7, 2020. https://www.commondreams.org/views/2019/11/25/realism-bernie-sanders-climate-policy)
In Aldo Leopold’s 1949 “Thinking like a Mountain,” the idea of a “community concept” of ethics comes up again. While all ethics hold the premise that the individual is a member of a community of interdependent parts, the land ethic broadens who, or what, is included in that “community,” expanding inclusion to soils, waters, plants, and animals. This way, a respect for plants, animals, waters, and the Earth as a whole, not just a respect for other humans, is deeply rooted in our ethics.

Blog 4. Let’s Talk About Ethics: Worldviews, Justice, and Education
Environmental ethics and philosophy are a great portion of environmental studies. Science would have no significant call to action for humans if we didn’t have a sense of right and wrong.
There are a few basic environmental worldviews that inform individuals beliefs on environmental issues. Human-centered (anthropocentric) environmental worldviews are primarily concerned with the needs and desires of humans. One such view is called the planetary management worldview, which holds humans as the hierarchically highest species, giving them the ability to manage the Earth however they see fit for their own personal requirements; the value of other species comes from how valuable they are to humans. There are three major variations: the no-problem school, the free-market school, and the spaceship-earth school. The first believes that environmental issues are solved through economic, managetary, and technological improvements. The second holds that a free-market global economy is the best thing for the environment, with minimal interference from the government. The third, and perhaps most abstract, views the Earth as a spaceship, that is, it is a complex machine that we can control.
A second anthropocentric view is the stewardship worldview, which declares that humans have an ethical responsibility, or obligation (depending on the strength of the view), to take care of the Earth. Some find this foolish because they believe it’s not the Earth that needs saving, humans do.
Some dismiss these worldviews all together because they assume that we have the knowledge and power to be effective stewards of the Earth. As it is now, the way we are “managing” the Earth is only benefiting us, and not even in the long-term. There is no evidence to support the idea of us successfully managing the Earth. Critiques of the global free-market point out that “we cannot have an unlimited economic growth and consumption on a finite planet with ecological limits or boundaries.” [1] Finally, the spaceship concept may be interesting but is far too oversimplifying and misleading.
Life-centered, or earth-centered, worldviews expand the boundaries of what life forms should be valued beyond humans. The environmental wisdom worldview believes that we should study nature and use it to guide us in living more sustainably, that we are a part of the community of life that sustains us and all other species, and that we are not in charge of the world. Research shows that becoming more environmentally literate is an important factor in environmental change.
Figure 1. A Guide to Environmental Literacy. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018.)
Research also shows, however, that education is not enough. We ought to foster a true ecological, aesthetic, and spiritual appreciation for nature, which happens primarily through experience in nature. Furthermore, an important factor in living more sustainably is consuming less. Not only does this benefit the environment, but it also combats the ethically questionable concepts of materialism and consumerism, and the idea that things can bring happiness. Research shows that people actually crave community, not stuff.
Figure 2. Ways to Live More Sustainably. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 693)
We also need to avoid two common views that lead to no effective change: gloom-and-doom pessimism and blind technological optimism. The first views the situation as too dire to combat, while the second puts too much hope in technology saving us without us putting in the work.
Environmental justice examines environmentalism through the lens of social justice. It recognizes that environmental issues aren’t purely natural, they are distributive, participatory, political, and cultural. It is an interdisciplinary field that combines humanities and hard sciences. In the U.S., the environmental justice movement rose as it became clear that “a disproportionate burden of environmental harms was falling on African Americans, Latino/a Americans, Native Americans, Asian Americans, the working class, and the poor” [2]. Beyond the U.S., environmental justice extends to issues of colonialism, the global environmental commons, and the effects of the corporate globalization.
I believe that a complete view of environmentalism must include environmental justice. Environmental issues are inherently linked to issues of wealth disparity, racism, and colonialism. Therefore, environmental solutions need to recognize the disproportionate effects of climate change in order to bring true, comprehensive change. For example, we must recognize that low-income communities and communities of color suffer more from being located near industrial plants or waste disposal sites than wealthier communities who have the resources to influence the location of those sites, or to choose to live elsewhere.
Intergenerational justice is the idea that current generations have obligations to past or future generations. Applied to environmentalism, it holds that those living now have a responsibility to preserve ecosystems and conserve resources for the next generations. While I think the idea of protecting Earth for future generations is not harmful in itself, I think it has the tendency to fall into anthropocentrism and therefore fails to address the issue comprehensively. Yet again, the focus is only on humans and not on the millions of other species that we are affecting through our environmental havoc. While it might be successful in inspiring care for the environment since it appeals to pride, it truly only reflects a care for ourselves, which I consider a failure. Other forms of intergenerational justice also consider future ecosystems, which I think is a much better form of the practice. Inclusivity of the “natural” with the human is the key to change.
Environmental citizenship is the idea that humans are a part of a larger ecosystem and that our future is dependent on each individual accepting the challenge and acting for change. Instead of human domination of the environment, humans are seen as members of the environment. It appeals to a sense of ethics similar to Aristotle’s virtue ethics. It internationalizes the concept of stewardship as it is more religiously neutral, and even clarifies the misunderstanding of human dominion for domination in Judeo-Christian traditions. While environmental citizenship is difficult to pin down, its general principle is helpful in educating and creating change due to its neutrality. Growing up in a primarily Christian community, I am far too familiar with the confusion of human dominion for human domination. I think that religiously neutral stances of environmentalism could be helpful in bringing about comprehensive and international change.
Another important idea is biophilia, an “innately emotional affiliation of human beings to other living organisms” [3]. There is research supporting the idea that the brain “has an evolved intelligence that grew out of the need for detailed information about nature” [4]. Nature also provides many benefits to human health and well-being, through direct contact, indirect contact, and simulations such as photographs. Windows, trees, and gardens are just a few elements of nature that have been shown to improve human behavior. However, it is also important to note how human attraction to nature has led to unsustainable practices, such as building hotels in the forest for panoramic views. Far too often our appreciation of nature is harmful to it.

Last Child in the Woods is a book about emerging research that shows how important exposure to nature is for healthy childhood development. Author Richard Louv comments on today’s “nature-deficit disorder” in children which could have ties to the rising rates of obesity, attention disorders, and depression. The book began the No Child Left Inside movement, focused on creating increased interest in children’s environmental awareness. The movement has impacted legislation and been endorsed by 58 organizations. In Milwaukee, WI, Riverside Park was once a place of crime and pollution, but after the introduction of an outdoor-education program and removal of a dam, the park has been restored. As one puts it, “nature was not the problem; it was the solution” [5]. The movement brings people together through agreement on one basic principle: “no one among us wants to be a member of the last generation to pass on to our children the joy of playing outside in nature” [6].
Finally, with all of this research and talk of the importance of education comes an important disclaimer: education does not guarantee decency. In fact, a large portion of damage is done by highly educated individuals. All of that to say, it’s not only a matter of educating, but a matter of how we educate. Fragmented education leads to fragmented worldviews. We need an educational revolution before we can have a sustainable revolution.

Blog 5. Let’s Talk about Environmental Policy: Economics & Politics
When we evaluate environmental issues we must recognize the fact that the basis of our economic systems is natural capital, and therefore environmental studies is inherently linked to economics. With that said, it’s important to know the three major economic systems: a centrally-planned economy (generally socialism), a free-market economy (generally capitalism), and a mixed economy.
Figure 1. The Three Major Economic Systems. (“Exploring the Major Economic Systems.” Weebly. Accessed February 18, 2020. http://wolverine2015.weebly.com/economic-system.html)
The difference in these systems stems from who determines production and distribution. A centrally-planned economy is controlled by the government, while the free-market economy is under the control of private individuals and companies. A mixed economy is controlled by a mix of the government and private sources. Most countries have mixed systems, for example the U.S. is majorly free-market with some regulation by the government. Free-market economies are governed by the principle of supply and demand. Most capitalistic economies are not purely free-market because they are influenced by other factors such as government subsidies, which are known to be harmful to the environment because they value economic growth over preserving ecosystems.
These major economic systems use three types of capital: natural, human, and manufactured. While these are all pretty self-explanatory it’s important to note the dependence on natural capital by the other types. Human capital only exists because of natural capital. Similarly, manufactured capital is built from natural resources.
There is a major controversy between economic growth and sustainability. Economic growth generally happens when the flow of resources through economic systems is increased. With such an increase in production comes an increase in pollution. Currently there is a push for environmentally sustainable economic development.
Figure 2. The Flow of energy and matter through economic processes. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 632)
The law of conservation of matter and the laws of thermodynamics tell us that natural capital is limited. According to an article published in 1997, the value of ecological systems was estimated to be on average a minimum of US$33 trillion per year, compared to global gross national product at an estimated US$18 trillion per year.
Ecological economists argue that we should shift our economic view from growth to innovation, development, and improvement. An example of such is termed the steady-state economy, in which all resources are recycled and reused in some way. There would be no “growth” as we often talk about, but we would be sustained and the economy would remain steady. Some criticize this model because it limits accumulation of wealth by individual people or groups. However, I see this as more of a benefit.
Some economists argue that we will not see change until we include the value of ecosystem services in market prices. Existence value is a proposed monetary value for resources just for existing, not necessarily for its use. Another is aesthetic value, reflecting the beauty of a landscape, species, or other part of nature. Finally, there is a bequest or option value that reflects how much people are willing to spend to protect natural capital for future generations.
Sustainable, or green, businesses, have a minimum or positive effect on the environment. Generally they meet the following criteria: [1]
1. It incorporates principles of sustainability into each of its business decisions.
2. It supplies environmentally friendly products or services that replaces demand for nongreen products and/or services.
3. It is greener than traditional competition.
4. It has made an enduring commitment to environmental principles in its business operations.
A common example is when a business “goes paperless” and sends electronic copies of things instead. The Leadership in Energy and Environmental Design (LEED) certification, developed to incentivize green building design in the U.S., is now very prestigious. Some examples of LEED certified buildings in NYC include the Greenwich Lane, One World Trade Center, and the Empire State Building.
Figure 3. One World Trade Center: a LEED certified gold building. (Gagiuc, Anca. “One World Trade Center and Four World Trade Center make list for largest LEED-certified buildings.” Benson Global. September 21, 2018. Accessed February 23, 2020. https://www.bensonglobal.com/2018/09/21/one-world-trade-center-and-four-world-trade-center-make-list-for-largest-leed-certified-buildings/)
The bottom line is that we need some sort of economic shift in order to be more sustainable. This shift will not happen on its own, though, it will require changes in policy.
Environmental issues are innately political due to the interconnectedness of economics, politics and laws. Environmental policy deals with “the body of laws, regulations, and programs that are designed, implemented, funded, and enforced by one or more governmental agencies” [2]. The government has the power to reduce environmentally harmful business practices through passing laws against, or regulating, them. Some people believe that the government is the best tool for battling environmental issues, while others shy away from too much governmental power. Environmental policy goes through a process called the policy life cycle (fig 4) that deals with problem recognition, policy formation, policy implementation, and policy adjustment. The triple bottom line principle advocates that we look at economic, social, and environmental needs together which each other in making policy decisions, instead of viewing them in isolation. I think this policy would encourage a more well-rounded set of laws than what we currently have, and yet again shows the importance of an interdisciplinary approach to environmental issues.
Figure 4. The policy life cycle. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 657)
Current environmental laws deal with the regulation of pollution, as seen in laws for air quality, water quality, waste management, contaminant cleanup, and chemical safety; resource sustainability, as seen in impact assessment, water resources law, mineral resources law, forest resources law, wildlife and plant law, and fish and game laws; and principles, such as sustainable development, equity, transboundary responsibility, public participation and transparency, precautionary principle, prevention, and the polluter pays principle.
Just recently the Trump administration has been seen trying to weaken a foundational environmental law: the National Environmental Policy Act (NEPA). NEPA was passed in order to make sure that government decisions that could potentially harm the environment are open to review by and involvement with the public. It has helped stop unnecessary projects and create more sustainable alternatives. With the law weakened, many projects would go unreviewed by the public potentially causing great environmental harm.
Not only is this an issue of environmental harm, it is also an issue of transparency. In politics, especially in countries that value democracy, the role of the public in making decisions is critical. As Miller reiterates, individuals matter. Politics is as much local as it is national, if not more. A good place to start in influencing environmental policy is in our own communities. For college students, such as myself, it is important to evaluate the greenness of our campuses, and take action to improve any matters not yet sustainable. Finally, we need to view environmental security as necessary for economic security, and as important as national security. Working with other countries is key, as we all inhabit the same earth.
In “Consumer or Citizen?” Ernest Partridge argues that our current political environment is failing in its assessment of individuals. People are viewed and treated more as consumers, interested in value, emotions, and personal satisfaction, than we are as citizens, interested in moral value, principles, and information. The distinction between consumer and citizen is the key to understanding the degradation of our political institutions and therefore the key to restoration. I believe that this shift in the view of citizens could also help environmentally, as individuals viewed as citizens would be more interested in ethics and accurate information when it comes to elections and political debate, which would leave less room for politicians preying on emotions and fabricating information purely because they can “sell” it well. A more functioning democracy would be a more environmentally secure society.

Blog 6. Let’s Talk about Growth: Human Population & the Economy
Human population growth has spiked over the last 200 years, no longer growing slowly. There are three important trends dealing with this growth: the rate of population growth may be decreasing but the population is still growing, population growth is unevenly distributed, and large numbers of people are moving to urban areas from rural areas. The growth of the human population raises the question: how many people can the earth support indefinitely? It is obvious that as the human population grows, so does our ecological footprint. But some argue that what we should really ask is what the cultural carrying capacity is. Meaning, how many people could live in “reasonable freedom and comfort indefinitely, without decreasing the ability of the earth to sustain future generations” [1]?
There are numerous population clock websites online showing real-time birth and death rates. On https://www.worldometers.info/world-population/, you can see how the “births today” value rises much faster than the “deaths today” value, yielding a net population growth. While writing this, the global population has grown by 13.2 million this year. While I was aware of how large populations were, to actually see the growth happening was eye-opening. However, I think it is absolutely necessary to examine the true motives and biases held by those advocating that we slow population growth in order to live more sustainably. The countries with the largest population sizes and growths are Asian and African, largely undeveloped, and are unfairly targeted in this argument. We need to consider why these countries are less developed than the U.S., and recognize the role developed countries play in exploitation of other countries.
Figure 1. World population growth by region since 1820. (Roser, Max, Ritchie, Hannah, & Ortiz-Ospina, Esteban. “World Population Growth.” Our World in Data. May 2019. Accessed February 29, 2020.)
With such rapid population growth, many anticipate future conflict with environmental limits. Many believe that we need encourage slowing the population growth through reducing poverty, empowering women, and supporting family planning. In the 1992 World Scientists’ Warning to Humanity, which I discussed in my first blog post, one of the scientists’ five calls to action was to achieve sexual equality, which is linked to slowing population growth. Studies have shown that women who are educated, can control their own fertility, and support themselves financially have fewer children. Giving women more rights and opportunities is critical. Only about 30% of girls around the world are enrolled in secondary education, and in almost every country women have fewer rights and opportunities than men. Female empowerment is a righteous pursuit in itself, and if through female empowerment we can also slow population growth to increase quality of life for humans and other species, and lessen our ecological footprint, then there is even more reason to pursue that end.
In addition, rapid population growth is linked to urbanization and issues of urban planning. Most urban areas are unsustainable with large ecological footprints, but there are many seeking to change this. For example, PlaNYC was a 2009 strategic plan by New York City Mayor Michael Bloomberg to create more sustainable housing for the future additional 1 million residents of NYC. Its three major components were OpeNYC, MaintaiNYC, and GreeNYC: preparing for 1 million new residents in the next two decades, repairing aging infrastructure, and reducing carbon emissions by 30%. Another term in urban planning is a transition town, which refers to grassroots community projects seeking to increase self-sufficiency and reduce effects of climate change and economic instability.
Another important question to ask in these discussions is why there’s an underlying assertion that poverty causes environmental issues. It’s more helpful to recognize how wealthier people have significantly larger ecological footprints per individual, and they are the ones who are actually educated about and have the resources to combat environmental issues. The textbook focuses primarily on the extremes: the dirt-poor and the top 1%. A much larger portion of people find themselves in the working class or lower middle class.
“The Impossible Hamster” is a short video clip arguing against many politicians’ and economists’ belief that the economy can grow indefinitely. They state that there are reasons for why things do not grow indefinitely in nature, and use the example of a hamster who doubles in size each week for a year, growing to a 9 billion ton hamster. This hamster would consume at least a year’s worth of the world’s corn production every day. With economic growth, we edge closer to very serious environmental limits. A limited environment cannot support unlimited growth of any kind.
Figure 2. The Impossible Hamster. (“The Impossible Hamster.” New Economics Foundation. Vimeo. January 24, 2010. Accessed February 29, 2020. https://vimeo.com/8947526)
In a related video, Mark Albion illustrates conflict between business and life. When a young MBA encounters an older fisherman coming back from the water, he lectures him on how he could spend more time fishing, get a bigger boat, and continue to grow his business until he ended up a millionaire in New York City. The fisherman asks “then what?” to which the MBA replies that he could then spend his days fishing and spending time with his family, all things which he already did in his day-to-day life without the 10-15 years of working and being absent from his family life. We see through this parable that being a millionaire is not necessary to have “a good life.” In fact, pursuing excess wealth can impede happiness.
In examining the state of our environment and economy, The Center for a New American Dream asks the question: how can we reduce ecological impact and create jobs? They offer a new economic model and way of life termed the plenitude economy, which rethinks how we spend our time and ultimately gives us better quality of life. The amount of hours we work has gone up about 200 hours a year since the 1970s, making us more stressed, tired, and unhappy. At the same time, it increases carbon emissions. Therefore, they argue that reducing work time would increase our quality of life while decreasing environmental harm. With more time off work, people would have more time to “D.I.Y” projects, like gardening, bee-keeping, sewing their own clothing, building low-cost eco-friendly housing, and generating their own energy. When people work less, they also consume less, and I’ve talked about the environmental harm of mass consumption before. The plenitude economy also encourages sharing, bartering, and community practices–building social capital.
Figure 3. The Degrowth Movement. (Demaria, Federico. “The rise - and future - of the degrowth movement.” The Ecologist. March 27, 2018. Accessed February 29, 2020. https://theecologist.org/2018/mar/27/rise-and-future-degrowth-movement)
Another economic model is called the steady state economy, defined by a constant stock of capital and a constant population size. The head individual of this position, Herman Daly, advocates for immediate political action to switch to the steady state economy. This would include imposing permanent government restrictions on all resource use. The model recognizes the limits of natural capital, which in turn limits economic growth. There is a related movement called the degrowth movement, which is based on ecological economics, anti-consumerist, and anti-capitalist ideas. It is another response to the question of whether growth is limited or not. The degrowth movement believes that overconsumption is at the heart of environmental and social issues. However, the degrowth movement does not believe that reducing consumption requires individual sacrifice or sacrificing happiness. Instead, they believe that happiness can be maximized through non-consumptive means like sharing work, devoting more time to art, music, family, nature, culture, and community. I think that materialism and overconsumption not only harms the environment but is also at the root of a lot of unhappiness. Our culture of always needing the newest things can create a competitive environment and make people feel lesser when they cannot afford certain goods. In a less materialistic society this source of unhappiness would be weakened.

Blog 7. Let’s Talk about Extinction
Humans play a role in the loss of species and ecosystem services, which is why extinction rates are sharply increasing. It is normal for species to go extinct, and we refer to its natural rate as the background extinction rate, which is approximately 1 species per year for every million species living on earth. Mass extinction is a term used to describe when many species go extinct in a short period of time. Thus far, the earth has experienced 5 mass extinctions, wiping out at least half its living species. Right now, biodiversity researches project the extinction rate to rise at least ten-thousand times the background rate. At this rate, up to 50% of the world’s 2 million identified species could go extinct by the end of the century. This means we are entering a sixth mass extinction primarily caused by harmful human activity. This tremendous loss in turn impacts the ecosystem services that required the species. In fact, the Millennium Ecosystem Assessment showed that 15 of 24 of the earth’s major ecosystems are in decline.
The “human activities” degrading the environment that we talk about include “destroying and degrading natural habitats, introducing invasive species, and increasing human population, pollution, climate change, and overexploitation.” [1] These are often abbreviated HIPPCO. We should care about these harmful behaviors and the potential mass extinction for many reasons. First, as Miller mentions, living species are a vital part of our natural capital. As I’ve discussed in this blog before, all major types of capital come from or are dependent on natural capital in some form. Without it, we would not have an economy. Living species provide ecosystem services that our lives and economies depend on.
Figure 1. Different types of natural capital and their uses. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 197)
However, there is another reason we should care about mass extinction of living species. Their value does not, or at least should not, be derived entirely from their usefulness to humans. Many in the environmentalist movement believe that these species have a right to exist on their own. This is an ethically founded viewpoint that again makes a distinction between anthropocentric and ecocentric worldviews. However, within this view we find some difficult questions. For example, if all species have a right to exist on their own, how do we decide which to help and which are less important? We will always reach a hierarchy of some kind, whether humans are on top or not.
Invasive species are one way in which natural habitats are interrupted. Although some invasive species include wheat, corn, poultry, and other livestock that make up the majority of our food supply in the U.S., they are often very harmful to natural habitats. Wild boars, for example, were deliberately introduced for the purpose of hunting for sport. The species reproduces so rapidly, and are so vicious, that they have wreaked havoc across the continental U.S. They do not have enough predators to control their population.
If a wild boar invaded and tore up my yard and my garden, I would most likely contact a professional to try to catch and eliminate the wild boar. Since they are so destructive and don’t seem to interact beneficially with many other species, I think this action would benefit the other species in the area, and the ecosystem as a whole.
Figure 2. Some different invasive species. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 201)
Due to the tremendous threat a sixth mass extinction poses, I believe we must enlist the help of laws and treaties to protect species. In the past, efforts like the Endangered Species Act (ESA) in the U.S. have proved successful–99% of the species listed in the act have been saved from extinction. These efforts should be more widespread. I think this is an area where we can apply the precautionary principle, which states that “when substantial preliminary evidence indicates that an activity can harm human health or the environment, we should take precautionary measures to prevent or reduce such harm even if some of the cause-and-effect relationships have not been fully established scientifically.” [2] Basically, even if we cannot be entirely sure that our efforts will be 100% successful, when it comes to irreparable damage, or anything we cannot undo, we must act even in our uncertainty.
In addition to focusing on individual species, we can also look at conservation efforts on an ecosystem scale. Some major ecosystems include forests and grasslands, both of which are at risk. Forests provide several important ecosystem and economic services, as summarized in figure 3. While some argue that we should not try to put a monetary value on irreplaceable ecosystem services, believing their value to be infinite, I think it is enlightening to recognize that if we do give them a monetary value, they are worth about $125 trillion annually.
Figure 3. Important ecosystem and economic service provided by forests. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 223)
Deforestation and forest fires due to the rise in temperatures are two forms of destruction of the forest ecosystem. These can lead to water pollution from erosion, acceleration of flooding, extinction of specialist species, habitat loss, and release of CO2 and loss of CO2 absorption. A specific type of forest that calls for our concern is tropical forests, which make up about 6% of earth’s land area, but contain at least half of the world’s known species of terrestrial plants, animals, and insects.
After forests, grasslands are the second most-used and altered ecosystem by human activities. They are at risk due to overgrazing, which kills the grasses and exposes the land to invasive species and erosion.
The best way to preserve terrestrial biodiversity is to strictly or partially protect areas from harmful human activity. Right now, about 6% of earth’s land is protected, leaving 94% up to exploitation by humans.
I support the effort to establish more wilderness areas in the United States to preserve critically important species and ecosystems. I find that most of the disadvantages of establishing are only negative when viewed from a short-term economic viewpoint. For example, some would argue that establishing more wilderness areas would slow economic growth by preventing certain areas from extraction of minerals, lumber, agricultural practices, etc. which there is a high demand for. However, I think if we think about natural capital in a long-term point of view, we can see that economic growth will always be limited by the abundance of natural capital, so destroying it now for temporary growth will eventually catch up to us.

Blog 8. Let’s Talk about Aquatic Biodiversity & Food Production
In chapter 11 of the textbook, Miller dives into aquatic biodiversity and ecosystems. Particularly, he examines the essential ecosystem services that aquatic systems provide, how they are being degraded, and how we can sustain them. Aquatic ecosystems are particularly affected by human activity because of proximity. It is estimated that approximately 80% of the world’s people live near the seacoast. Most major cities are port cities on a coast somewhere. Humans dump alarming and dangerous amounts of waste into oceans on a regular basis. The UNEP estimates that land-based coastal activities contribute about 80% of all ocean pollution. The three greatest threats to aquatic biodiversity are pollution, climate change, and overfishing.
First, one example of the effect of pollution on aquatic ecosystems deals with runoff. When large amounts of plant nutrients flow from land into the ocean, algae bloom on a great scale. When these algae die, they sink and are decomposed by bacteria, which requires oxygen. When so much oxygen is removed from the water, other marine organisms are either forced to leave or suffocate. In addition, toxic pollutants from industrial areas deplete biodiversity by killing off organisms. Finally, the presence of plastic in the ocean from garbage is responsible for the death of over a million seabirds and mammals every year, when they mistake the plastic for food.
The concern over plastic in the ocean gained the spotlight recently, inspiring the switch away from plastic straws, shopping bags, and cups. There has been a mainstream shift from single-use plastic to reusable alternatives, and that shift is pushed by legislation. While there is no federal ban on single-use plastics, many states have passed their own laws, including California, New York, Hawaii, Connecticut, Delaware, Maine, Oregon, and Vermont. Most of these bans focus on plastic bags, and impose a charge per bag (such as 5-10 cents for each bag used). While these bans are helpful, I think the fact that they only exist in 8 of our 50 states is extremely underwhelming. I think it is also interesting to note that all of the states with bans are on a coast, with the exception of Vermont. The biggest question that arises with the spread of these bans is: are they actually effective in reducing harm to aquatic biodiversity? The answer is debatable. The critical factor to consider is if the replacements for the single-use plastics are much better. In addition, we have yet to see a decrease in plastic waste and plastic production is still expected to double by 2040. While the bans might not be the most effective thing, they certainly help raise awareness about environmental degradation by human activity, and invite research for sustainable alternatives. As a final note, while alternatives are helpful, it is most important to reduce consumption first and foremost.
Figure 1. Map of the U.S. indicating status of legislation against plastic bag use. (“State Plastic and Paper Bag Legislation.” NCSL.org. January 24, 2020. Accessed March 17, 2020. https://www.ncsl.org/research/environment-and-natural-resources/plastic-bag-legislation.aspx)
Second, climate change also threatens aquatic ecosystems. Oceans are responsible for absorbing the majority (about 90%) of the excess heat that has arised due to the warming of the atmosphere. It won’t be able to do this forever, though. In addition, this excess heat is warming the ocean, affecting food webs and rendering some habitats intolerable to their species and therefore leads to migration of species.
A third factor of harm to aquatic ecosystems is that of overfishing. Data shows that 87% of the world’s commercial fisheries have been fully exploited or overfished. This has effects including scarcity of commercially valuable fish (cod, marlin, swordfish, and tuna), exploitation of other ocean species, and thousands of workers losing jobs.
Some ways we can work to sustain marine biodiversity include establishing marine sanctuaries, expanding marine reserves, and restoration. As of right now, about 98% of the ocean remains unprotected from harm caused by human activity. If we want to sustain aquatic biodiversity, we need to protect our oceans immediately. First, we should identify aquatic biodiversity hotspots that are under particularly harmful circumstances, and protect them. Next, we should protect lakes and rivers by restricting pollution. Finally, we should seek to incentivize those who live on or near protected waters so that all benefit from the changes.
Chapter 12 of the textbook looks at the relationship between food production and the environment. Many health problems that exist today stem from not eating enough nutritious food, and, in some cases, eating too much food lacking nutrition. Nearly 800 million people on Earth suffer from hunger on some level.
Figure 2. Food pyramid diagram demonstrating how eating meat requires wealth. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 285).
Most of the world’s hunger appears in poorer areas where people can only afford to eat a low-protein, high-carbohydrate, vegetarian diet (fig. 2). In more developed nations, low-income individuals rely on cheap food with high fat, sugar, and salt. Both hunger and overnutrition lead to a lower life expectancy, greater susceptibility to disease and illness, and lower productivity and life quality.
Food production relies almost entirely on three systems: croplands, rangelands, and fisheries. Croplands provide grains, rangelands provide meat, and fisheries provide fish. The specialization of food is a risky game. We rely on about 14 plant species to provide about 90% of the world’s food calories. There are an estimated 30,000 total edible plant species. Similarly, we eat a small fraction of mammals and fish. Specialization violates biodiversity, and if these few key species go extinct then our food as we know it will be completely uprooted.
The industrialization of food production has environmental effects. First, perhaps the most prominent effect is the loss of biodiversity that occurs when grasslands, forests, and wetlands are converted to croplands and rangelands. Soil is affected by erosion, loss of fertility, salinization, water-logging, and desertification. Water is affected by aquifer depletion, increased runoff, pollution from pesticides, and algal blooms. Farming causes a lot of air pollution, particularly by increasing methane emissions from cattle.
Some ways to produce food more sustainably include “using resources more efficiently, sharply decreasing the harmful environmental effects of industrialized food production, and eliminating government subsidies that promote such harmful impacts” [1]. Individuals can aid in this process by making personal choices about the food that they eat, as listed in figure 3.
Figure 3. Individual actions that can improve sustainability of food production. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 316)
For example, Growing Power, Inc. is an ecologically based urban farm that produces organic food. If I were a member of Growing Power and tasked with transforming an abandoned suburban shopping center into an organic farm, I would seek to repurpose the preexisting resources. The water system could be transformed into an irrigation system for crops, the rooms could be used for storage, the parking lot could become farmland, etc. By using what’s already there, we reduce unnecessary consumption and also save money.
What becomes clear through reading these two chapters is that human activity is having an effect on natural ecosystems, which in turn affects human health. While this simply reinforces previously held ideas, it can be enlightening to read about the connection to the food industry, and shows how truly pervasive environmental issues are in every facet of human life.

Blog 9. Let’s Talk about Food Production: Industry & Soil
Food production in the United States, and many other countries around the world, has changed drastically with industrialization. Two documentary films that expose some secrets and harmful practices of the food industry are 2008’s Food, Inc., and 2012’s Symphony of the Soil. In Food, Inc., director Robert Kenner examines corporate farming in the U.S.. The film concludes that the industry is inhumane and environmentally harmful. In the past, food production was greatly focused on self-sustaining farming, in which individuals/small groups provided for themselves. Over time, however, agricultural technology and food production developed on a wide scale. This industrialized version of food production has many environmental and ethical quandaries. The film looks at three specific things: the industrial production of meat, the industrial production of grains and vegetables, and economic and legal powers in food production.
Today, large industries control the vast majority (around 80%) of the beef industry. They pay farmers to mass produce animals, making them bigger over a shorter period of time. The animals are raised in extremely confined spaces with little room to move, making them fatter, and are fed corn and steroids to make them grow faster. This raises questions of morality. Is this treatment of animals morally upright? The film argues that it is not, and that if the average person was aware of it, they would agree that it is wrong. I think the feelings the movie produces while watching the way the chickens, for example, are treated speak for themselves. At least for me personally, it was extremely difficult to watch. I think that the average meat consumer creates a false distinction between that type of treatment and the meat that they personally consume in order to feel okay in doing so. Perhaps a lot more people would be vegan or vegetarian if they had to personally raise and slaughter the animals that they ate, but when it’s a process so far removed from the consumer, it can be overlooked. The animals are also filled with a number of different chemicals, often undisclosed to the consumer. Because consumers are unaware, corporations choose chemicals that are cheaper, but often more harmful.

Furthermore, in an article about a poultry plant, writer Steve Stifler talks about the inhumane, unethical treatment of the workers, not just the animals. Workers may get decent benefits, but the environment of the workplace and the actual work they do is miserable. Stiffler mentioned a sign in the plant that read, “Democracies depend on the political participation of its citizens, but not in the workplace” [1]. I think it’s important to also recognize this aspect of unethical treatment because people are generally unaware of this as well. And, in general, I think most consumers would prefer to support establishments that treat their workers with dignity and respect.
The industrial production of grains and vegetables is also examined, with particular focus on corn. One of the featured authors is Michael Pollan, who wrote the famous Omnivore’s Dilemma, examining the food process from start to finish. Since corn is so easily and quickly mass-produced it is widely used for both human and animal consumption. Today, nearly all the products in our grocery stores contain some corn-derived ingredient. Many of them contain corn-based syrup, and are highly processed foods. Because corn is so ingrained in the food industry, the average American consumes way too much corn-related nutrition than is healthy. The production of corn also requires a lot of land, with approximately 30% of the U.S.’s land being used for corn.
When it comes to economic and legal powers in the food industry, we find a huge issue with false or misleading advertising. While consumers are overwhelmingly uninvolved in the food-making process, companies are the culprits of using deceitful images and advertising for their products. Overall, consumers need to take on more responsibility in choosing what they eat–knowing who grew it, what it was fed, where it comes from, etc.–and regulations for food advertising need to be more strict. The majority of meat products feature some sort of image of a red barn with green fields. Advertisers appeal to an old-fashioned, traditional, “American Dream”-esque ideal that gives consumers a sense of familiarity and health.
In Symphony of the Soil, director Deborah Koons Garcia examines the organic farm industry in contrast with industrial food production, and does so with a specific appreciation of soil. It dives into questions of how to restore the fertility of soil. Soil is the foundation of all growth, and holds a lot of history. In the documentary, biologists and geologists examine the soil of Hawaii and Norway. They demonstrate how soils are formed and changed over time. They detail 11 different types of soil, from most fertile to most arid. Prairie soil is the most productive, because its deep roots undergo a process of death, providing nutrition in the soil, and it holds water. While prairie soil is relatively rare in the world (making up only 7% or so,) it is relatively abundant in the U.S. (making up about 22.5%). This speaks to the development and history of the food production in the U.S.. Soil is an ecosystem in itself, providing the resources necessary for all other growth.
In collaboration with organic farmers, the documentary declares that the best way to replenish the fertility of our soils is by giving back to the soil what was taken from it. Soil is stripped of its nutrients through excessive plowing, and the use of chemical fertilizers and pesticides. They advocate for composting, cover crops, and drip lines. Not only will the soil be restored, but it will continue to replenish itself. In one farmer’s testimony, eight inches of rich topsoil were created in five years. Many individuals and chefs agree that organic meats and vegetables are better. The film demonstrates the beauty of the growth and life sustained by fertile soil, and invokes a feeling of appreciation and admiration of the resource. With these, the film hopes to inspire change in the treatment of soil, and ultimately hopes to transform food production in the U.S. from an overwhelmingly industrial field to a more organic industry.
Both of these films approach the industry of food production in unique ways. Food, Inc. is largely interested in exposing the harms caused and produced in food production, inspiring viewers to act on their disgust and distaste for the unethical, economically unsustainable, and environmentally unsustainable practices. Symphony of the Soil approaches it a bit differently, inspiring viewers to act on a newfound appreciation for soil and its beauty, giving them hope. Both are powerful in making viewers rethink their consumption of food. The next time they sit down at the dinner table, they may start to ask themselves questions previously unexamined. Where did this food come from? What is in it? Who produced it? How are laborers treated? and so on…

Blog 10. Let’s Talk about Hazards: Health & Waste
In this post, I will address the relationships between health hazards and environmental harms. To begin, there are five major types of health hazards: biological hazards, chemical hazards, natural hazards, cultural hazards, and lifestyle choices. Biological hazards involve harmful pathogens that cause diseases in other organisms. The most prevalent example is COVID-19, commonly referred to as “the coronavirus,” which is a highly infectious flu-like virus currently plaguing nations across the globe. It is spread significantly by asymptomatic carriers of the virus, and is causing significant harm due to the lack of a vaccine to prevent its spread, unlike the more common seasonal flu. With such rapid spread, local, state, and national governments are enacting “stay-at-home” social distancing efforts in order to “flatten the curve.” Essentially, by decreasing the number of new cases per day we can help deter our healthcare system from being overwhelmed, and therefore reduce the number of deaths caused by the virus. Without doing this, the virus may not last as many months, but a significantly higher number of people would die. This level of global outbreak is referred to as a pandemic, and it does not appear to be going away anytime soon, despite the thoughts of U.S. President Donald Trump. There are now over a million cases worldwide, and the numbers are growing exponentially.
Figure 1. The COVID-19 Pandemic as of April 2, 2020. (“Coronavirus latest: confirmed cases cross the one-million mark.” nature. April 1, 2020. Accessed April 5, 2020. https://www.nature.com/articles/d41586-020-00154-w)
The textbook mentions that “an especially potent flu virus could spread easily around the world in a pandemic that could kill millions of people in only a few months” [1]. This is eerily reminiscent of what we see happening in the world right now. While social distancing efforts may be helping, I cannot help but think how the pandemic would be different if the virus was taken more seriously as a threat to the U.S. and preventative measures were put into effect sooner. The ironic thing about preventative measures is that in order to enact them you have to convince skeptical people that without them, the outcome would be much worse. But in doing so, you will never be able to prove that you were right and that the threat was truly dire. This is similar to action against climate change. Skeptics do not believe environmental activists when we argue that without action against climate change, we will suffer serious consequences in the near future. By enacting measures against climate change, however, we will never be able to prove those theoretical disastrous outcomes. I believe this is part of what makes preventative action so difficult to enact and justify.
Chemical hazards come in three major toxic agents: carcinogens, mutagens, and teratogens. The first group can cause cancer, the second causes mutations, and the third causes birth defects. Recently, I watched the film Dark Waters which detailed the unregulated use of the chemical PFOA (perfluorooctanoic acid) by the chemical manufacturer DuPont. PFOA was used to make Teflon pans, but it is a “forever” chemical, meaning it is not broken down over time. It stays unchanged in the bloodstream and accumulates to toxic levels. The chemical was not included in any chemical references, and had been dumped into rivers for disposal. The chemical can cause blackened teeth, bloated organs, and tumors. After years of investigation, a scientific review concluded that PFOA can cause multiple cancers and diseases in living organisms. Unfortunately, cases like this are not uncommon. Chemical manufacturers have been irresponsibly disposing of their hazardous waste for years, harming the environment and long-term human health.
To test the toxicity of chemicals, scientists often use animals, which gives rise to another controversial debate over ethics. However, laboratory testing is not entirely comprehensive as it tests chemicals in isolated, controlled conditions that are not necessarily valid representations of humans’ complicated daily lives.
Figure 2. A look at the chemicals we come in contact with frequently. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 460)
Many argue that any chemicals suspected to cause significant harm to the environment or human health should not be released/dumped into nature. Others advocate for recycling and reusing them in other chemical processes, such as companies like DuPont. One of the best things we can do as individuals is stay informed about and involved with possible risks in order to reduce potential harm.
In addition to chemical hazards, we also face potential harm from solid and hazardous wastes. Solid waste is a direct output of human existence. Especially in affluent nations, our enormous amounts of trash overwhelm our environment. Unlike nature which recycles its nutrients, humans produce massive amounts of waste that end up being burned or in a landfill. The two major types of solid waste are: industrial (produced by mines, farms, and industries) and municipal (commonly referred to as trash or garbage). A good portion of municipal solid waste ends up as litter in natural landscapes and waters. For example, a few weeks ago I covered the controversy over single use plastic bags, and how they pollute our oceans, rivers, lakes, and so on.
Figure 3. A breakdown of municipal solid waste in the U.S.. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 576)
Harmful solid waste includes industrial solvents, hospital medical waste, car batteries, household pesticide products, dry-cell batteries, and sludge from incinerators and coal-burning plants. Released into the environment, these wastes cause air pollution, water pollution, degradation of ecosystems, and serious health threats. A big and growing category of waste is electronic– computers, cell phones, televisions, etc. that are no longer being used. Reports show that more developed countries produce between 80-90% of the world’s hazardous waste.
There are two main approaches to dealing with solid waste. First, there is waste management, which looks at controlling wastes in an effort to limit environmental harm. The second is waste reduction, which looks to produce less solid waste in general, using the principles of reusing, recycling, and composting. Combining these principles, we get integrated waste management. Figure 4 shows the difference between how we should manage our waste (by reducing first and foremost) versus how we actually do manage our waste (by burying the majority of it).
Figure 4. Analysis of waste management in the U.S.. (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 579)
Individuals can ask themselves four questions to assess waste management: “Do I really need this? How many of these do I actually need? Is this something I can use more than once? Can this be converted into the same or a different product when I am done with it?” [2]. These questions address refusing, reducing, reusing, and recycling, respectively. Individuals reducing their own waste could have a great environmental impact. This is reminiscent of the concept of voluntary simplicity we studied earlier. Perhaps in recognizing the permanence of many wastes and the great risk they pose to the environment and human health, people will more readily switch to a lifestyle of voluntary simplicity.

Blog 11. Let’s Talk about Water: Consumption & Pollution
In chapter 13 of the textbook, Miller talks about water resources and the issues they face. The abundance of water on earth is part of what makes our planet so unique and welcoming to life. Water covers about 71% of Earth’s surface and makes up about 60% of the human body. Water itself is a unique chemical that helps sustain life in every facet. There is no substitute for water. Something that goes unnoticed by a lot of us is how much water is used for things other than drinking. Water is a necessary component in supplying food and other resources we use daily. To get a better idea of this, you can calculate your “personal water footprint,” on https://waterfootprint.org/en/resources/interactive-tools/personal-water-footprint-calculator/.
Figure 1. My personal water footprint. (“Personal Water Footprint.” Waterfootprint.org. Accessed April 19, 2020. https://waterfootprint.org/en/resources/interactive-tools/personal-water-footprint-calculator/).
My personal water footprint came out to 709.6 m3 per year, which is about 400 less than the global average. A majority of my water footprint comes from meat, followed by food items such as vegetable oil, starchy roots, and sugar, and then dairy. Very little of it comes from cereal, fruit, and vegetables. Previously, I was unaware how much water is used to supply meat goods. I had heard that vegetarianism/veganism is better for the environment, but now seeing a specific reason why is insightful. I am curious as to why the global average is so high, and how much lower a vegetarian’s water footprint would be.
With that said, our precious water is grossly mismanaged. As talked about a bit in previous blog posts, our oceans and waters are tainted with pollution and waste. Water is greatly undervalued, which is part of what leads to its waste and pollution. What makes the situation even worse is that freshwater is not safe and accessible to everyone around the world. Access to freshwater is a global health issue, an economic issue, a national and global security issue, and an environmental issue. In fact, it is estimated that over four thousand people die from waterborne infectious diseases every day because they do not have safe drinking water. Water is vital to our economies because of its role in the production of food and energy. Finally, there are tensions between countries about the limited accessibility of freshwater, and misuse of freshwater affects nature’s processes.
Because such a small fraction of freshwater is available to us, there is a search for ways to increase freshwater supplies. Two popular methods are large dam-and-reservoir systems and the conversion of saltwater to freshwater. However both of these methods are extremely flawed. Dam systems disrupt ecosystems and the conversion of saltwater is expensive and requires a lot of energy. The best way to maximize our available freshwater is to use it more sustainably, which the book states would be by cutting water waste, raising water prices, slowing population growth, and protecting aquifers, forests, and other ecosystems that store freshwater. One point that sticks out to me is the proposition of raising water prices. While I understand this would discourage waste and pollution of the precious resource, I question its social and political effects.
Human activity is affecting the water cycle in many ways. For example, through overdrawing groundwater aquifers for agricultural irrigation, pollution of freshwater and saltwater, and alteration of the surface of the earth. It is critical for humans to reduce overall water use in order to protect the unique and precious resource.
Following along with water resources, chapter 20 of the textbook discusses water pollution. This pollution comes from two types of sources, point and nonpoint. The former deals with sources that pollute waters from specific locations, such as drain pipes. The latter deals with broader sources of water pollution, such as runoff. One of the biggest culprits of water pollution is agricultural activities. Every type of water pollutant has an effect, as demonstrated by figure 2.
Figure 2. Water Pollutants and their Effects (Miller, G. Tyler. Living in the Environment. National Geographic Learning/Cengage Learning, 2018, 545).
One very prominent case study is the Flint Michigan Water Crisis. A public health crisis that began in 2014, the Flint water crisis is still an issue today. It came about after the city’s water source was changed, and individuals noticed differences in their water. It was found that the water contained toxins and dangerous levels of lead. The issue is not expected to be solved until July of this year, if at all.
In order to address situations like the Flint water crisis and others, water testing is very important. In addition, most natural sources of water are self-cleaning, but they require time to rid themselves of pollutants and toxins. Time that they do not have when they are being constantly overwhelmed by waste. At least 80% of raw sewage is discharged directly into waterways in less developed countries. This is particularly disturbing because those same waterways are relied on for drinking water, water to cook and do laundry with, etc.
While groundwater is greatly polluted by chemicals from agriculture, industry, transportation, and homes, efforts to prevent pollution are much more effective than efforts to purify already-polluted groundwater. Though some waters can cleanse themselves, groundwater is not very good at doing so. Groundwater is also the major source of water for U.S. residents, and is often polluted unknowingly, causing major public health threats. Yet again, this relates back to the film Dark Waters I discussed, in which the pollution of waters by an unregulated chemical was linked to several serious diseases such as cancer.
The use of bottled water is controversial because, although it provides people with safe drinking water, it is often used when it does not need to be, and the plastic bottles contribute to the pollution of water sources. Only a small fraction of plastic water bottles used in the U.S. are actually recycled. The production of bottled water also requires huge amounts of energy, making it less than ideal.
There is legislation regarding safe drinking water in the U.S., but many call for strengthening the existing legislation by combining smaller drinking water treatment systems with others in order for them to meet federal standards, enforcing requirements concerning public notification of violation of drinking water standards, and banning the use of toxic lead in plumbing pipes.
As individuals, though, there are still ways we can help below the federal level. For example, we can use organic alternatives to commercial inorganic fertilizer, minimize use of pesticides, stop yard wastes from getting into storm drains, stop using water fresheners in toilets, stop flushing medicines, and stop pouring pesticides, paints, solvents, or other chemicals down the drain or on the ground. Change on the individual level, when echoed by thousands of others, can truly make a difference. In addition, individuals can work with their local governments to address safe drinking water legislation, and call for action on the federal level if necessary. As always, individual discretion regarding consumption and waste makes a big difference!

Blog 12. Let’s Talk about the Future: The Anthropocene & Transformation
In The Human Planet: How We Created the Anthropocene, authors Lewis and Maslin begin their discussion of whether or not “Homo dominatus [can] become wise” by speculating on the three possible futures of the world: “continued development of the consumer capitalist mode of living towards greater complexity; a collapse; or a new mode of living” [1]. The first is essentially continuing life as usual, while successfully using innovation and technology to avoid a collapse or switch to a new mode of living. The second entails a global collapse taking place as environmental degradation catches up to us. The final outcome sees civilization adapting to a new mode of living, something drastically different from our current way of life, as suggested by the previous modes of living: the hunter-gatherer, agricultural, mercantile, industrial, and consumer capitalist.
Currently, our capitalist mode engages in two main feedback loops. We solve problems using the scientific method and invest profits into the production of more profits. While these positive feedback loops can be applauded for things like decreasing poverty and increasing lifespans, they can also be criticized for causing environmental degradation, extreme inequality, and uncooperative, competitive communities.
Lewis and Maslin argue that the second and third options are not as far off as we may think. “Energy availability, information flows and our collective human agency are increasing at ever faster rates,” they say, pointing to the transformations of the generation and processing of information, the increasing human demand for energy, and the increasing population size growth and interconnectedness [2]. All of these factors demonstrate how transformations now will not take as long as they have in the past, because with each transformation the world changes so drastically it is no longer under the same set of conditions to accurately be compared to itself. While this could point to a new mode of living, it also raises the possibility of collapse, since exponential trends cannot continue infinitely on a finite planet.
When investigating the possibility of collapse, a general conclusion we can draw is that “the greater the power humans have, the greater the opportunity for such power to be used for the most damaging of ends” [3]. While an Anthropocene collapse could happen, that is, one caused by human-related environmental change, a human-caused technological collapse is also a possibility. Threats such as nuclear warfare and bioterrorism are growing day by day. The biggest threat we face is climate change, which emerges from the fact that “[today’s mode of living] is powered by energy sources that are undermining the ability of today’s globally integrated network of cultures to persist” [4]. A study found that economic growth, population, and other factors showed steady increases between 1970 and 2000, yet the environmental effects of those increases put a strain on the system in the early twenty-first century that eventually led to collapse by mid-century.
To assess the rate and magnitude of climate change, the book examines cumulative emissions of carbon dioxide. The degree of warming deemed acceptable differs country-to-country, and even between politicians within a country. Generally, limits between 1.5 and 2°C are acceptable. However, for small island states, any warming is troubling due to the threat of rising sea levels. Because the rise in temperature does not directly correlate to cumulative carbon emissions, we are left to guess exactly what level of global carbon emissions is okay. To have even an okay chance at not exceeding the 1.5-2°C limit, greenhouse gas emissions need to decrease drastically, nearing zero by 2050. In order to do this, Lewis and Maslin point out an absolutely critical need: valuing the eradication of greenhouse gas emissions at the same level of importance as the pursuit of economic growth.
As discussed many times in previous blog posts, climate change is a direct outcome of our consumer-capitalist mindset and tendencies, which value economic growth over just about any other factor, whether that be the environment or human quality of life. We’ve seen governments giving subsidies that directly harm the environment in order to boost economic growth. We’ve seen individuals sacrificing quality of life in order to please capitalistic governments in participating in competitive innovation-centered markets. And we’ve seen how this way of living is not sustainable in “The Impossible Hamster” graphic demonstration which taught us that infinite growth is not sustainable on a finite planet.
Our systems are plagued by a greed for money and power that makes it difficult to conceive of this goal as possible. For example, “fossil fuel extraction and use is subsidized at a rate of about US$5 trillion a year … Tax breaks and financial transfers are hard to reduce because nineteen out of the top twenty-six oil and gas companies in the world are partly or fully nationalized” [5]. Since these companies make money for the governments that own them, they will continue to receive special treatment in an effort to compete with other nations. The interconnectedness between the economy, fossil fuel companies, and nations’ governments makes the necessary banning of fossil fuels an incredibly daunting task.
This raises another concern: the balance of economic power. The global economy is roughly split between North America, Europe, and Asia, meaning the West cannot solve climate change alone. It must be solved by global cooperation, planning, and action. As discussed in previous posts, affluent nations like the U.S. are wealthy in part because they exploited other nations and are responsible for at least a third of the extra carbon dioxide in the atmosphere. Less-developed nations are entirely less responsible for climate change, but experience more of the harmful effects of it. This leads to the Anthropocene conundrum: “how to equalize resource consumption across the world within sustainable limits” [6]. The UN Paris Agreement shows how we are tackling this issue, by expecting high-emitting countries to do more to reduce emissions, and providing income-poor countries with financial and technological assistance.
Some pathways to reduce emissions involve technologies like Bioenergy Carbon Capture and Storage (BECCS), which actively removes carbon dioxide from the atmosphere. This is an attractive method because it delays when we need to take action, perhaps giving us time to develop climate change-combatting technologies. While it makes sense in an economic model, as it shows that “a million dollars of impacts today, once discounted to 100 years in the future, amounts to just $6232 of damage” [7], it does not hold strong in an ethical sense. How we leave the Earth for future generations is a conversation of ethics.
Another important thing to consider is the realistic nature of economic growth. Lewis and Maslin point out that “a century from now the global economy is expected to have doubled four times over” [8]. In addition to the environmental effects of an economy sixteen times larger, is it possible for people to be sixteen times more productive at work? We cannot physically accomplish working a 128-hr week into a day. Neither the environment nor humans can cope with such growth.
To conclude their discussion, Lewis and Maslin explain two important ideas to further investigate dealing with the Anthropocene. The first is how we spend our time, and the second is that the Earth’s surface should be allocated half to humans and half to the other millions of living species on Earth. They advocate for a Universal Basic Income, Half-Earth rewilding, clean energy, Artificial Intelligence, and the Internet as helpful tools in the combat against climate change, but not the answer. An absolutely necessary factor is collective action of individuals in order to accomplish a redistribution of power and wealth. An environmentally sustainable future will also have greater equality, as the two go hand-in-hand.
