Playgrounds of the Future: How Urban Design Shapes STEM Skills in Children

Children’s play is essential not only for physical and social development but also for nurturing the critical thinking, creativity, and problem-solving skills foundational to STEM education. Recent research comparing children’s play in Auckland, New Zealand, and Venice, Italy, offers valuable insights for urban planners, educators, and STEM advocates.

In Auckland, playgrounds are designed primarily with safety in mind—fenced, buffered from traffic, and equipped with traditional play structures. While these spaces provide caregivers with peace of mind, they often function as isolated “refuge islands,” limiting children’s independent mobility, social encounters, and opportunities for diverse, spontaneous play.

In contrast, Venice’s car-free streets and piazzas serve as vibrant, shared spaces where children engage in a wide range of creative activities like playing ball, drawing on pavements, climbing statues, and watering plants. This self-organizing play culture fosters risk competency, spatial awareness, and social skills, all of which are integral to STEM learning.

The study highlights the importance of designing urban spaces that balance safety with freedom, incorporating natural elements, loose parts, and “risky art” to encourage open-ended exploration. It also stresses the value of involving children in urban design through participatory approaches, recognizing their right to shape their environments.

For STEM professionals and educators, these findings underscore how thoughtfully designed play environments can serve as informal STEM learning hubs, where curiosity, experimentation, and problem-solving flourish naturally.

As cities evolve, integrating these principles can help cultivate the next generation of innovators, equipped with the resilience and creativity needed to tackle complex challenges.

Young Forests, Big Impact: Peak Carbon Removal Happens Between 20–40 Years

Young secondary forests, those regenerating on lands previously cleared of mature woodlands, play a critical and often underappreciated role in combating climate change. A new international study published in Nature Climate Change highlights that forests aged 20 to 40 years exhibit the highest carbon removal rates, sequestering up to eight times more carbon per hectare than newly regenerating forests.

Key findings:

🔹Carbon removal rates vary by biome; tropical moist forests reach peak sequestration earlier than boreal and Mediterranean forests.

🔹Protecting existing young secondary forests offers immediate and substantial carbon removal benefits. Delaying regeneration efforts significantly reduces potential carbon sequestration.

🔹If 800 million hectares of restorable forest begin regenerating in 2025, up to 20.3 billion metric tons of carbon could be removed by 2050. Delays of five to ten years could reduce this potential by 25% to 50%.

🔹Advanced STEM methodologies—including satellite remote sensing, machine learning models, and extensive field data—enable precise mapping and prediction of forest carbon dynamics globally.

🔹The upcoming COP30 summit in Belém, Brazil, represents a pivotal moment for policymakers to prioritize forest protection and restoration as essential climate mitigation strategies.

For STEM professionals and students, this research underscores the importance of interdisciplinary approaches combining ecology, data science, and climate policy to maximize natural carbon sinks. Protecting and restoring young forests is a cost-effective, scalable solution that complements technological climate innovations.

As global demand for rapid carbon removal intensifies, integrating young forest conservation into climate action plans is essential. The window for maximizing these natural solutions is narrow, making immediate policy and scientific engagement critical.

Canada’s Plastic Crisis Demands STEM Solutions as Global Treaty Talks Resume

Plastic pollution represents a critical global challenge that threatens ecosystems, human health, and climate goals. Approximately 40% of global plastic production is single-use packaging, the largest source of plastic waste. Without decisive action, plastic waste is projected to nearly triple by 2060, reaching 1.2 billion tonnes.

Canada exemplifies this crisis, generating 3,268 million tonnes of plastic waste annually, with only 9% recycled. The majority of plastics, except PET bottles, are difficult or uneconomical to recycle due to complex material mixes, resulting in 2.8 million tonnes of plastic waste, equivalent to the weight of 24 CN Towers, ending up in landfills yearly. This is unsustainable, especially as Ontario faces landfill capacity limits by 2035.

Plastic pollution extends beyond landfills. Around 1% of Canada’s plastic waste leaks into the environment, breaking down into microplastics found in tap water, food, farmland, and even human bodies. Scientific evidence links micro- and nanoplastics to metabolic, immune, and reproductive disorders, raising urgent public health concerns.

Canada’s 2022 ban on single-use plastics, informed by extensive scientific data and public consultation, has already yielded measurable reductions in plastic litter, such as a 32% drop in plastic straws on shorelines in 2024. However, political debates continue to challenge evidence-based policies.

As global negotiations resume for a legally binding plastics treaty under the United Nations Environment Programme, science-based policy and STEM innovation are critical. Developing sustainable materials, improving recycling technologies, and enforcing effective regulations will be essential to curb plastic pollution’s environmental and health impacts.

For professionals and students in STEM fields, this is a call to innovate and advocate for solutions that protect ecosystems and human well-being. The future depends on integrating science, technology, and policy to achieve a zero-plastic-waste world.

Smoke in the Countryside, Trouble in the City: How Upland Fires Are Polluting Urban Air

Air pollution is often seen as an urban challenge, but new research reveals that rural upland fires can have a significant—and often overlooked—impact on air quality in cities. In October 2023, smoke from controlled heather burning in the Peak District drifted over nine miles to Sheffield, causing PM2.5 levels to spike well above World Health Organization guidelines and prompting health concerns among residents.

This incident highlights a broader issue: the routine burning of the UK’s peat-rich uplands. Peatlands cover around 12% of the UK, store an estimated 3.2 billion tons of carbon, supply 70% of the nation’s drinking water, and provide critical habitats for wildlife. Yet, more than 80% of English peatlands are classified as degraded, often due to historic air pollution, draining, overgrazing, and repeated burning.

Despite their ecological importance, most official air quality monitoring focuses on urban areas, leaving the effects of rural fire pollution largely undocumented. The FireUp project is addressing this gap by deploying a network of air quality sensors, leveraging satellite data, and engaging local communities to detect and measure pollution from upland fires. This integrated approach offers a clearer understanding of pollution patterns, supporting better planning and stronger public health protections.

Key insights:

🔹Controlled burning on peatlands releases significant PM2.5 pollution, impacting rural and urban air quality.

🔹Current regulations and monitoring systems are limited, with most enforcement resources concentrated in cities.

🔹Satellite analyses reveal that unlicensed burning is more widespread than official records suggest.

🔹The FireUp system demonstrates how STEM innovation and citizen science can improve environmental monitoring and inform policy.

🔹The next steps include developing a citizen science app that empowers individuals to report peatland fires and contribute to air quality data.

As the UK government reviews regulations and upland fire risks increase, evidence-based approaches are essential for shaping sustainable land management and public health policies. This is a prime example of how STEM-driven solutions and community engagement can address complex environmental challenges and drive progress toward a healthier, more sustainable future.

Vermont’s Plastic Bag Ban: A Landmark STEM-Backed Success in Sustainability

In July 2020, Vermont implemented one of the nation’s most comprehensive single-use plastic bans, targeting plastic carryout bags, expanded polystyrene (Styrofoam) containers, plastic stirrers, and restricting plastic straws to “upon request.” This law, known as Act 69 of 2019, also introduced a 10-cent fee on paper bags to encourage reusable alternatives.

A 2025 University of Vermont study surveying 745 residents revealed the law’s dramatic impact:

✅ Plastic bag use dropped by 91% within two years, nearly eliminating single-use plastic bags from Vermont’s retail and food service sectors.

✅ Paper bag use increased by only about 6%, a change researchers deemed statistically insignificant, indicating that most consumers switched to reusable bags rather than substituting one disposable option for another.

✅ Approximately 70% of Vermonters supported the legislation, reflecting strong public approval and community buy-in.

Why did this policy work so well?

🔹STEM-Driven Research: Environmental science and economics informed the design, showing how fees and bans influence consumer behavior.

🔹Behavioral Science Insights: The 10-cent fee on paper bags motivated many shoppers to adopt reusable bags, while clear communication and public education eased the transition.

🔹Comprehensive Scope: By banning multiple single-use plastics simultaneously, the law tackled a significant portion of Vermont’s plastic waste stream—nearly one-third of landfill trash.

Mercury Pollution in Rivers Has More Than Doubled Since the Industrial Revolution — A Global STEM Challenge

New research led by Tulane University reveals that mercury levels in the world’s rivers have more than doubled since the pre-industrial era, rising from about 390 metric tons per year before 1850 to roughly 1,000 metric tons today. This dramatic increase is primarily driven by human activities such as wastewater discharge, soil erosion, industrial processes, and especially artisanal and small-scale gold mining (ASGM).

Mercury is a potent neurotoxin that accumulates in aquatic food chains, contaminating fish and posing serious health risks to humans and wildlife. Regions like the Amazon basin, East Asia, and North America are particularly affected. For example, the Amazon River alone now transports over 200 metric tons of mercury annually, with about 75% coming from human sources like mining and deforestation. In East Asia, industrial mercury releases dominate, with rivers such as the Yangtze showing more than a twofold increase compared to pre-industrial times.

This study used advanced process-based computer modeling (MOSART-Hg) combined with sediment core data from around the world to reconstruct mercury transport through river systems over centuries. The model’s accuracy helps identify pollution hotspots and quantify the impact of human activities on the global mercury cycle.

Why does this matter?

🔹Mercury contamination threatens ecosystems and human health, especially in communities relying on fish as a food source.

🔹Rivers act as major pathways transporting mercury from land to oceans, influencing global environmental health.

🔹Understanding mercury flows is crucial for tracking progress toward international goals like the Minamata Convention on Mercury, which aims to reduce mercury pollution worldwide.

How can STEM help?

🔹Environmental scientists analyze mercury sources and impacts on ecosystems.

🔹Engineers develop cleaner mining and industrial technologies to reduce mercury emissions.

🔹Data scientists and modelers refine tools to predict mercury transport and assess mitigation strategies.

🔹Policymakers use scientific evidence to implement effective regulations and international agreements.

Farm Plastic: From Waste to Wonder!

Did you know that every year, farmers use millions of kilometers of plastic twine to tie hay and straw bales? Most of this plastic ends up burned or dumped in landfills, polluting the environment and wasting valuable resources.

But here’s the good news: Australian researchers, together with Ritchie Technology, have created a compact, affordable recycling machine that lets farmers process dirty, used bale twine right on their farms! Instead of tossing it away, farmers can melt the twine and turn it into useful new products like garden planters, fence posts, outdoor furniture, or even decking boards.

Why is this a game-changer?

🔹Reduces Pollution: Burning or dumping plastic releases toxins and microplastics into the air, soil, and water. Recycling on-site keeps these harmful materials out of the environment.

🔹Saves Money: Farmers spend less on waste disposal and can even make extra income by selling recycled plastic products.

🔹Supports the Circular Economy: The same plastic gets reused again and again, instead of becoming waste after just one use.

🔹Inspires Innovation: This technology could be applied to other farm plastics, such as silage wrap or irrigation tubing, sparking even more creative recycling solutions.

🔹This is a perfect example of how science, engineering, and sustainability can work together to solve real-world problems. If you’re passionate about protecting the planet, think about how you could help invent or promote new ways to recycle and reuse!

Agrivoltaics: The Future of Farming and Solar Energy

Agrivoltaics is an innovative approach that combines solar energy production with agriculture by installing solar panels above crops or pastures. This design allows farmers to continue growing food and raising animals while simultaneously generating clean, renewable electricity. By sharing the same land for both purposes, agrivoltaics maximizes land use efficiency and helps address two critical global challenges: food security and sustainable energy supply.

One of the key benefits of agrivoltaics is its ability to protect crops from extreme weather conditions such as intense sunlight, hail, or strong winds. The partial shading from solar panels can reduce heat stress on plants and lower water evaporation from the soil, which improves crop resilience and reduces irrigation needs. Additionally, some studies have shown that agrivoltaic systems can boost overall land productivity by producing both food and energy on the same acreage.

A recent comprehensive study by the University of Bonn surveyed nearly 2,000 people and found that agrivoltaics enjoys significantly higher public acceptance than traditional solar parks. Nearly 44% of respondents expressed willingness to pay a premium for electricity generated from agrivoltaic farms, compared to only 29% for conventional solar parks. This higher acceptance is largely because agrivoltaics preserves agricultural activity and maintains the rural landscape, making it more appealing to communities.

While agrivoltaics may involve slightly higher upfront costs and can reduce crop yields marginally in some cases, the long-term benefits of diversified income streams for farmers and the dual production of food and clean energy present a compelling, sustainable solution. This approach exemplifies how interdisciplinary STEM innovations—spanning agriculture, renewable energy engineering, and environmental science- can create practical solutions that benefit people, farms, and the planet.

As we face the intertwined challenges of climate change, energy demand, and food security, agrivoltaics offers a promising pathway toward a resilient and sustainable future.

The Atmosphere is Getting Thirstier, Making Droughts More Severe Worldwide

Droughts are intensifying not just because of less rainfall but because the atmosphere itself is demanding more water, a phenomenon called atmospheric evaporative demand (AED) or “atmospheric thirst.” As global temperatures rise, the air becomes hotter, sunnier, windier, and drier, pulling more moisture from soils, plants, rivers, and lakes.

Think of rainfall as your income and AED as your spending. Even if your income stays the same, if your spending rises, you go into deficit. That’s exactly what’s happening with drought: the atmosphere’s growing thirst is drying out the land faster and deeper, worsening drought conditions, even where rainfall hasn’t dropped significantly.

Recent research shows:

🔹AED is responsible for about 40% of the increase in drought severity globally over the past 40 years.

🔹In the western U.S., including California and Nevada, AED is projected to increase by 13–18% by the end of this century, driving longer droughts and more extreme wildfire risk.

🔹From 2018 to 2022, drought-affected land expanded by 74%, with 58% of that increase linked to rising atmospheric thirst.

🔹Regions like western and eastern Africa, the southwestern U.S., Australia, and Europe are especially vulnerable.

Why does this matter?

🔹AED intensifies water stress on ecosystems, agriculture, and human communities.

🔹It challenges water resource management, requiring smarter irrigation, drought-resistant crops, and improved soil health.

🔹Incorporating AED into drought monitoring and climate models improves prediction accuracy and resilience planning.

🔹STEM fields—climate science, hydrology, and environmental engineering—are essential to understand and mitigate these impacts.

What can we do?

🔹Develop and deploy water-efficient technologies and drought-adaptive agriculture.

🔹Restore natural landscapes to improve soil moisture retention and reduce evaporative losses.

🔹Advance climate research integrating AED to inform policy and community preparedness.

This growing atmospheric thirst is a clear signal that climate change affects not only how much rain falls but also how quickly water disappears. STEM-driven innovation and sustainable practices are critical to securing water and food supplies for future generations.
