  • Bringing the chill of the cosmos to a warming planet

    SkyCool Systems manufactures panels that can be incorporated into existing cooling systems to reduce the amount of electricity needed to turn hot air into cold air. The technology is based on radiative cooling and utilizes a thin, mirror-like film engineered using nanotechnology to send heat into space while absorbing almost no radiation. It lowers the temperature of objects by more than 10 degrees and doesn’t require electricity or special fuels, so it does not produce greenhouse gases. While piloting the panels, a grocery outlet saved over $3,000 in electricity costs over the course of just one summer.

  • Bug Breeders Are Cultivating Waste-Guzzling Flies to Gobble Up America's Trash

    A growing number of bug breeders in the United States are raising black soldier flies to tackle greenhouse gas emissions, land degradation, and food waste. The larvae can convert waste into fertilizer for crops, while also reducing carbon dioxide emissions. In one experiment at Louisiana State University, about two tons of cafeteria food waste is processed by the fly larvae. Creating a similiar system on a larger scale for municipalities can be expensive, but the flies could be a multifaceted solution to the country’s trash problem.

  • Kenyan engineers recycling plastics for bricks

    Gjenge Makers Ltd is an alternative building product manufacturing company that creates products – such as pavers and blocks – out of recycled plastics. Founded by four Kenyan engineers, the team began by studying the manufacturing process and researching what products would do well on the market. They then built all of the machinery themselves, which break down the plastics, and then mix them with other building material products to ultimately create customizable plastic bricks that can withstand larger weight and are less expensive than concrete. They are popular in rural and lower-income areas.

  • The Sudbury model: How one of the world's major polluters went green

    After being known as a polluted mining town, politicians, scientists, industry officials, and residents of Sudbury, Ontario, were able to come together to restore its land. After 40 years and $33.5 million, they are about halfway through recovering about 200,000 acres of land. So far, they’ve been successful at restoring air quality, neutralizing soil to allow for replanting, and restocking lakes with fish. While some locals think the mining companies should have done more, the collaborative spirit could be a model for other communities looking to improve the environment.

  • The daring plan to save the Arctic ice with glass Audio icon

    The nonprofit Arctic Ice Project is testing an unusual approach to combat climate change: by scattering a thin layer of reflective glass powder over parts of the Arctic. By putting this material on top of the ice, they’re studying if the powder can protect the ice during the summer months and rebuild it over time. In one pond in Minnesota, just a few layers of the material made young ice 20 percent more reflective and delayed the melting of the ice. Other scientists question the impact the material can have on the Arctic ecosystem, but the approach could be a way to counteract the effects of global warming.

  • University of Arizona researchers unveil new model for desert farming in warming world

    In an experimental garden in Arizona, scientists are seeing how to produce sustainable and local food in a desert environment. They’re growing plants under a photovoltaic “canopy” of solar panels that provide necessary shade for the crops and, at the same time, generate cheap, renewable energy for irrigation systems and farm equipment. So far, they’ve been able to grow basil, Anasazi red beans, and a special bell pepper. While not all crops will work in this system and scaling the garden has its challenges, learning how to grow food in the desert is necessary to adapt to a future with climate change.

  • How Efforts To Save Hawaii's Forests Are Preventing A 'Freshwater Crisis'

    Landowners, state employees, environmental groups, and local hunters are working together to protect Hawaii’s forests and drinking water by eradicating invasive plants from the state’s protected forests. By allowing native plants to flourish, these forests could help combat climate change by sequestering carbon and allowing freshwater quivers to recharge with rainfall. Since 2013, the state has built 132 miles of fence to keep grazers away from forests to prevent the spread of seeds of invasive plants. However, this method can be expensive; a 1,400-acre fence cost over a million dollars.

  • Hawaii Marines Now Guarding The Nests Of Endangered Species Audio icon

    Members of the Marine Corps in Hawaii often pull double duty: military training and endangered species protection. For example, in June, the Marines roped off 13 green sea turtle nests on a local beach. Part of their job is to evaluate the potential environmental impacts of where they perform their training exercises. Sometimes there are military members or residents who might not understand why they have to preserve and manage the land, but education outreach has led to a ramp up in conservation efforts for turtles, birds, and other creatures.

  • Lawmakers want to revive FDR's Depression-era "tree army" to help boost rural economies

    The Civilian Conservation Corps (CCC) was a New Deal program to build outdoor recreation facilities, creating thousands of jobs during the Great Depression and building iconic state parks. Delaware programs, like the Senior Corps that enlists the help of people over 55, encourage civic engagement modeled after the CCC. Pennsylvania's Outdoor Corps hires young people to restore public lands over the summer. Congress introduced bills to revive CCC-like initiatives that could support rural economies hit hard by the Covid-19 pandemic, but environmental funding is not a priority of the current administration.

  • Hold the Salt: The Promise of Little Fresh Fishes

    In Myanmar, aquaculture production from medium-sized freshwater farms is growing and could be an important and sustainable supplier of food for the world’s growing population. Aquaculture businesses are thriving in Southeast Asia despite the decline of wild fisheries — the acreage of cultivated fishponds in some regions has expanded by more than 250 percent. While some environmentalists argue that it damages ecosystems, research suggests that freshwater aquaculture have a much lower environmental impact than marine fish farming.
