From the article:

But, as Brownell explained to new customers, Smart is different from the typical craft store: Everything on its shelves has been donated. The shop is what is known as a creative reuse center. These crafting thrift stores keep leftover and unwanted art supplies out of landfills, and instead get them into the hands of other creators at affordable prices. Smart combines that model with another mission. Many of the employees and volunteers who run the shop are adults with disabilities. Over the last decade, the organization has diverted more than one million pounds of art and craft materials from landfills, while providing over 37,400 hours of job coaching, volunteering and employment for adults with disabilities.

I think this is a really great example of how expansive environmental work can be--and how it can coincide with other forms of community action.

Protests and politics aren't the most effective or sustainable form of action for everyone (though there are more diverse ways to participate in that kind of action too!)--providing a service to your community that increases sustainability and aligns with your passions and interests is also an extremely valid and needed form of environmental action.

Once brought in for commercial or hobbyist reasons, invasive fish are not only threatening to edge native species out of the food chain in Malaysia and elsewhere, but they also spread diseases and cause great damage to local environments. Invasive fish are a problem the world over, but experts say the issue is keenly felt in mega-biodiverse Malaysia.

“More than 80 percent of rivers in the Klang Valley have been invaded by foreign fish species, which can cause the extinction of the rivers’ indigenous aquatic life,” said Dr Kalithasan Kailasam, a river expert with the Malaysia-based Global Environment Centre.

“It’s growing in almost all other main rivers in Malaysia,”

Alarmed by the threat, a small group of citizens banded together to fight the aquatic invaders. Led by Haziq, they are working to reclaim Malaysia’s rivers one fin at a time.

Further research then led him to learn about the threats posed by invasive species.

Haziq started to attract like-minded anglers, and, in 2022, they decided to form a group for hunting suckermouth, meeting nearly every week in a river to carry out a cull.

Their public profile and popularity are growing. The group’s membership has now grown to more than 1,000, and it has a strong fan following on social media.

“People kept asking how to join our group, because we were looking at the ecosystem,” Haziq said.

A lot of these "plastic alternative made from plants" products actually use at least a small amount of plastic mixed with the plant fibers. However, that does not appear to be the case here--they are truly making plastic-free packaging and cardboard coating even if that means their products do not have all of the same desirable characteristics as plastics.

A quote from the article:

“We're not going for the easiest win,” she says. “We're not going to mix our product with a bit of plastic to make a semi-natural product because that's a bit easier. We're going to go for it even if it's the hardest thing, to make sure it's truly natural.” 

Notpla, the company which makes seaweed-based packaging to replace single-use plastics, started with its two French and Spanish founders, Pierre Paslier and Rodrigo Garcia Gonzalez, experimenting in their student kitchen while at Imperial College London.

Now, Notpla has replaced more than 21 million items of single-use plastic across Europe, and is aiming to displace 1 billion units by 2030. In partnership with Just Eat, Notpla’s packaging was used at the UEFA Women’s Final at Wembley Stadium, London in 2022. From seven types of folded carton board boxes that year, it has grown into a catalogue of over 50 different designs. 

And the company is launching a new deli range, featuring plastic-free windows so people can see their sandwiches before buying. Honsinger hopes this will help Notpla branch out into office catering and museums, where that sneak peek is important.

From the article:

New research from Colorado State University and Cornell University shows that the presence of solar panels in Colorado’s grasslands may reduce water stress, improve soil moisture levels and — particularly during dry years — increase plant growth by about 20% or more compared to open fields.

One of the biggest downsides to renewable energy sources is that they usually take up more physical space--and therefore more habitat--than fossil fuels. However, there is increasing evidence that combining solar panels with certain food crops or types of habitat can actually be beneficial to both!

This study is particularly heartening because it implies that solar panels may help certain ecosystems weather the increased droughts brought on by climate change.

Article

"Cassiano is the founder of Teto Verde Favela, a nonprofit that teaches favela residents how to build their own green roofs as a way to beat the heat without overloading electrical grids or spending money on fans and air conditioners. He came across the concept over a decade ago while researching how to make his own home bearable during a particularly scorching summer in Rio.

A method that's been around for thousands of years and that was perfected in Germany in the 1960s and 1970s, green roofs weren't uncommon in more affluent neighborhoods when Cassiano first heard about them. But in Rio's more than 1,000 low-income favelas, their high cost and heavy weight meant they weren't even considered a possibility.

That is, until Cassiano decided to team up with a civil engineer who was looking at green roofs as part of his doctoral thesis to figure out a way to make them both safe and affordable for favela residents. Over the next 10 years, his nonprofit was born and green roofs started popping up around the Parque Arará community, on everything from homes and day care centers, to bus stops and food trucks.

When Gomes da Silva heard the story of Teto Verde Favela, he decided then and there that he wanted his home to be the group's next project, not just to cool his own home, but to spread the word to his neighbors about how green roofs could benefit their community and others like it.

Pictured: Jessica Tapre repairs a green roof in a bus stop in Benfica, Rio de Janeiro, Brazil.

Relief for a heat island

Like many low-income urban communities, Parque Arará is considered a heat island, an area without greenery that is more likely to suffer from extreme heat. A 2015 study from the Federal Rural University of Rio de Janeiro showed a 36-degree difference in land surface temperatures between the city's warmest neighborhoods and nearby vegetated areas. It also found that land surface temperatures in Rio's heat islands had increased by 3 degrees over the previous decade.

That kind of extreme heat can weigh heavily on human health, causing increased rates of dehydration and heat stroke; exacerbating chronic health conditions, like respiratory disorders; impacting brain function; and, ultimately, leading to death.

But with green roofs, less heat is absorbed than with other low-cost roofing materials common in favelas, such as asbestos tiles and corrugated steel sheets, which conduct extreme heat. The sustainable infrastructure also allows for evapotranspiration, a process in which plant roots absorb water and release it as vapor through their leaves, cooling the air in a similar way as sweating does for humans.

The plant-covered roofs can also dampen noise pollution, improve building energy efficiency, prevent flooding by reducing storm water runoff and ease anxiety.

"Just being able to see the greenery is good for mental health," says Marcelo Kozmhinsky, an agronomic engineer in Recife who specializes in sustainable landscaping. "Green roofs have so many positive effects on overall well-being and can be built to so many different specifications. There really are endless possibilities.""

Pictured: Summer heat has been known to melt water tanks during the summer in Rio, which runs from December to March. Pictured is the water tank at Luis Cassiano's house. He covered the tank with bidim, a lightweight material conducive for plantings that will keep things cool.

A lightweight solution

But the several layers required for traditional green roofs — each with its own purpose, like insulation or drainage — can make them quite heavy.

For favelas like Parque Arará, that can be a problem.

"When the elite build, they plan," says Cassiano. "They already consider putting green roofs on new buildings, and old buildings are built to code. But not in the favela. Everything here is low-cost and goes up any way it can."

Without the oversight of engineers or architects, and made with everything from wood scraps and daub, to bricks and cinder blocks, construction in favelas can't necessarily bear the weight of all the layers of a conventional green roof.

That's where the bidim comes in. Lightweight and conducive to plant growth — the roofs are hydroponic, so no soil is needed — it was the perfect material to make green roofs possible in Parque Arará. (Cassiano reiterates that safety comes first with any green roof he helps build. An engineer or architect is always consulted before Teto Verde Favela starts a project.)

And it was cheap. Because of the bidim and the vinyl sheets used as waterproof screening (as opposed to the traditional asphalt blanket), Cassiano's green roofs cost just 5 Brazilian reais, or $1, per square foot. A conventional green roof can cost as much as 53 Brazilian reais, or $11, for the same amount of space.

"It's about making something that has such important health and social benefits possible for everyone," says Ananda Stroke, an environmental engineering student at the Federal University of Rio de Janeiro who volunteers with Teto Verde Favela. "Everyone deserves to have access to green roofs, especially people who live in heat islands. They're the ones who need them the most." ...

It hasn't been long since Cassiano and the volunteers helped put the green roof on his house, but he can already feel the difference. It's similar, says Gomes da Silva, to the green roof-covered moto-taxi stand where he sometimes waits for a ride.

"It used to be unbearable when it was really hot out," he says. "But now it's cool enough that I can relax. Now I can breathe again."

Perhaps it's just me. But right now, with the rapid global transition towards green energy, reforestation and conservation efforts, laws, genuinely crazy and huge innovations that can help us adapt to the changing world... it feels like we're on the right track.

Perhaps it's just me. But the geopolitical insanity that I see and learn from my peers all over the world, doesn't feel like the end. No, it... it feels like change. The last horrible and panicked gasps of the dying old, because it refuses to accept that it is not sustainable anymore, and the world is moving towards the better, through protests and unity and human goodness. I've seen this before - in stories from the older generation, and in history books.

But I also feel terribly guilty whenever I start thinking like that, for some odd reason? I feel guilty whenever I try and rationalize that despite it all, the world will continue existing, and even in the worst case scenario (which we already have avoided), there would be forests and oceans and species and biodiversity and ecosystems and people and cities and countries to see and love, because after all, nature is resilient and adaptable - just like our species are.

I feel guilty for feeling this cautious curiosity about what the future might hold for us, the bad and the good. Because I feel like I am obligated to be grieving and panicking and angry, like many people are - but that's just... so tiring.

Hi Anon,

This is going to be a long one because I think your ask gets at something difficult that I have a lot of thoughts about.

Your phrase “cautious curiosity” made me think of psychology researcher Jamil Zaki’s idea of “hopeful skepticism”. Which is not assuming that everything will inevitably get better, but open to the possibility that it could and curious to see the paths it might take to get us there.

Our society tends to view a cynical outlook as more intelligent or even more moral, but research shows that a cynical outlook actually makes people worse at predicting outcomes, worse at cognitive and problem-solving tasks, less likely to vote or protest, and even measurably harms their physical and mental wellbeing.

I think the guilt you describe is likely coming from the feeling that while we have been significantly improving conditions for humanity on this Earth and will likely continue to do so in the long run, in the present there are many real humans suffering--it can be hard and uncomfortable to hold these two truths together.

Even if this last dying breath is temporary and brief, it is destroying real people’s lives and many more live in fear that they will be next. The fact that child mortality has absolutely plummeted even just in my own lifetime is both a miracle of humanity and means little to the parent who has lost their child to a preventable death. To quote the philosopher Max Roser, “The world is much better; the world is still awful; the world can be much better.”.

You don't need to feel guilty for having hope for the future. Carrying feelings like hopelessness, grief, and fear all the time is entirely valid, but like you said it is also exhausting—and there is nothing inherently moral about emotionally suffering particularly if it’s harming your ability to live your life or take positive action.  

You are right that we are still making progress in the correct direction in many ways. You are right that history is rife with examples of forward momentum provoking a reactionary backtracking but that the forward momentum usually ultimately prevails.

The key here, is to understand that the future path you describe is possible—even likely more probable than a lot of people think—but it is not inevitable. We still have to take action to make it happen. The arc of history bends towards progress only because so many millions of mostly unnamed unknown people have put the work in to bend it in big and little ways.

I’ll end with one of my favorite quotes from Rebecca Solnit: “Hope is not a lottery ticket you can sit on the sofa and clutch, feeling lucky. It is an axe you break down doors with in an emergency. Hope should shove you out the door, because it will take everything you have to steer the future away from endless war, from the annihilation of the earth's treasures and the grinding down of the poor and marginal... To hope is to give yourself to the future - and that commitment to the future is what makes the present inhabitable.”

Reminding others that progress is still happening and that there is hope for a brighter future is important work in getting members of your community to pick up their own axe and make that future happen. Hope in dark times is not just ok or reasonable--it is a precious, vital tool.

Firstly, the researchers removed the phones’ batteries and replaced them with external power sources to reduce the risk of chemical leakage into the environment, a ScienceDaily report explains. 

Then, four phones were connected together, fitted with 3D-printed casings and holders, and turned into a working prototype ready to be reused.

“Innovation often begins not with something new, but with a new way of thinking about the old, re-imagining its role in shaping the future,” says Huber Flores, Associate Professor of Pervasive Computing at the University of Tartu in Estonia.  

The prototype created by researchers was put to use underwater, where it participated in the monitoring of marine life by helping to count different sea species. 

Normally, these kinds of tasks require a scuba diver to record video and bring it to the surface for analysis. The prototype meant the whole process could be done automatically underwater.

And there are many other ways that a phone’s capacity to efficiently process and store data can be put to good use after its WhatsApping days are done.

These mini data centres could also be used at bus stops, for example, to collect real-time data on the number of passengers. This could help to optimise public transportation networks.

Such smartphone repurposing is just a drop in the ocean of issues that natural resource mining, energy-intensive production and e-waste present. Ultimately, we need to challenge this throwaway culture and move to a more circular model.

Using Leftover Restaurant Oyster Shells to Rebuild Oyster Reefs

From this article in the New York Times:

Summer in New England means lobster rolls, fried seafood and, of course, freshly shucked oysters. But there’s a problem. Those empty shells usually end up in a dumpster instead of back in the water, where they play a key role in the oyster life cycle. Oyster larvae attach to shells, where they grow into adults and form reefs that improve water quality, prevent coastal erosion and create habitat for other marine life. Two men in Connecticut are working to fix that. They’ve started a statewide program to collect discarded shells from local restaurants, dry them and return them to Long Island Sound for restoration projects. “We fill that missing piece,” said Tim Macklin, a co-founder of Collective Oyster Recycling & Restoration, the nonprofit group leading the effort. It’s one of several shell recycling programs that have emerged to help reverse the steep decline in oyster populations along U.S. coastlines, a drop that experts largely attribute to overharvesting, habitat degradation and disease. Some of the largest programs process more than a million pounds of shell each year.

The world’s largest sand battery has started working in the Finnish town of Pornainen

Capable of storing 100 MWh of thermal energy from solar and wind sources, it will enable residents to eliminate oil from their district heating network, thereby cutting emissions by nearly 70 per cent.

Launched just as Russia cut off gas supplies in retaliation for Finland joining NATO, the project was a timely example of how renewable energy could be harnessed in a new way.

Finding a way to store these variable renewables is the crux of unleashing their full potential. Lithium batteries work well for specific applications, explains Markku, but aside from their environmental issues and expense, they cannot take in a huge amount of energy.

Grains of sand, it turns out, are surprisingly roomy when it comes to energy storage.

It’s quite a simple structure to begin with, Polar Night Energy said of its prototype. A tall tower is filled with low-grade sand and charged up with the heat from excess solar and wind electricity.

This works by a process called resistive heating, whereby heat is generated through the friction created when an electrical current passes through any material that is not a superconductor. The hot air is then circulated in the container through a heat exchanger.

The sand can store heat at around 500C for several days to even months, providing a valuable store of cheaper energy during the winter. When needed, the battery discharges the hot air - warming water in the district heating network. Homes, offices and even the local swimming pool all benefit in Kankaanpää, for example.

“There’s really nothing fancy there,” Markku says of the storage. “The complex part happens on the computer; we need to know how the energy, or heat, moves inside the storage, so that we know all the time how much is available and at what rate we can discharge and charge.”

In Pornainen, Polar Night Energy has found a sustainable material in crushed soapstone; a by-product of a Finnish company’s manufacture of heat-retaining fireplaces.

"Tulikivi is a well-known and traditional company,” says Naskali. “The soapstone they use is a very Finnish thing.”

This brought tears to my conservationist heart today.

The continued existence of these species is the legacy of so many people whose names we will never know--some of who never lived to see the impacts of their work.

When you count up the flaws of our species, you have to count the good things too--out of the many species throughout Earth's history that have caused the demise or endangerment of other species, we are the only one that tries to fix it out of our fascination and love for other life forms.

The Green Economy is Now the Fourth Largest Market Sector Globally

From this report by the London Stock Exchange Group:

As of Q1 2025, the global green economy, if considered as a standalone sector, would account for 8.6% of listed equities with a combined market capitalisation of US$7.9 trillion. This would make it the fourth largest sector by market capitalisation, following Technology, Industrial Goods and Services, and Health Care.

"Despite significant uncertainties, electric cars’ market share is on course to exceed 40% by 2030 as they become increasingly affordable in more markets, new IEA report shows."

From something that was very unusual to see on the road not all that long ago, EVs are becoming a very popular alternative to internal combustion cars--enough so that even people who don't care about the environmental benefits are jumping on the EV train.

EVs require less maintenance, are cheaper to operate, and data on high mileage EVs implies that they will last significantly longer than internal combustion vehicles. All these factors make them very appealing as commercial fleet vehicles as well as private cars.

They're also getting significantly cheaper, even without government incentives. Since EV technology is advancing so quickly, used EVs lose their value more quickly than traditional cars and can be a fantastic bargain.

On the environmental side, switching from an internal combustion car to an EV actually becomes more and more environmentally beneficial as we switch more of our power generation to renewables. We're also rapidly learning how to make EV batteries that last longer and can be constructed with less environmentally impactful materials.

"If you're hoping that reef-restoring coral larvae will settle down in damaged reefs, you can't just sit around and wait for it to happen. You have to get out there and entice the larvae, which is exactly what a new algae-based gel is designed to do.

While we may think of coral reefs' "skeletons" as being composed solely of calcium carbonate produced by coral polyps, much of the material is in fact generated by what are known as crustose coralline algae.

Along with contributing greatly to the structural integrity of reefs, the algae-produced calcium carbonate also serves as a home to planktonic coral larvae. Once those formerly free-swimming organisms settle in and become polyps, they start producing reef-building calcium of their own.

It's a good arrangement for the coral, but it also benefits the algae.

Not only does the reef itself provide the algae with protection from the elements, the coral polyps also emit ammonia which the algae feed upon. It is therefore in the algae's best interest to entice any coral larvae that may be swimming past in the water column. In order to do so, the algae release metabolite chemicals that attract the larvae.

Led by Dr. Daniel Wangpraseurt, scientists at UC San Diego's Scripps Institution of Oceanography have now incorporated those metabolites into a gel that can be applied to degraded coral reefs. Called SNAP-X, the substance reportedly boosts coral larval settlement by up to 20 times as compared to untreated surfaces.

If the algae metabolites were just applied to the coral on their own, they would soon dissipate in the water, leaving the coral larvae unable to follow them to their source. For that reason, the researchers started by encasing the chemical molecules in durable silica nanoparticles. Those particles were then suspended within a biocompatible liquid blend of gelatin methacrylate and polyethylene glycol diacrylate.

When that liquid is sprayed or painted onto a surface – such as a piece of dead coral – then exposed to ultraviolet light, it polymerizes into a hydrogel form. That gel is capable of clinging to the surface for up to one month while immersed in flowing water, gradually releasing its larvae-attracting nanoparticles as it does so.

Initial lab tests showed that application of SNAP-X resulted in a six-fold increase in larval settlement. Subsequent tests that more accurately simulated the water flow on coral reefs, however, produced the 20-times figure.

It should be noted that all of the tests conducted so far have involved a single type of coral, but Wangpraseurt believes the technology should work on other species with a few tweaks.

"I think this material is a breakthrough that can hopefully make a big contribution to coral restoration," he says. "Biomedical scientists have spent a lot of time developing nanomaterials as drug carriers, and here we were able to apply some of that knowledge to marine restoration."

A paper on the research was recently published in the journal Trends in Biotechnology."
