  • Indigenous Colombians mount a spiritual defense of the Amazon

    Five different Indigenous groups formed an alliance known as the Union of Traditional Age Medics of the Colombian Amazon to practice spiritual ceremonies and community healing based on the ingestion of a potent hallucinogenic tea known as yagé. These groups are at risk of physical and cultural extermination due to deforestation. By engaging in traditional yagé ceremonies, they use their traditional knowledge and spiritual wisdom to help make decisions and retain their autonomy in the rainforest.

  • How AI Can Help Save Forests

    Satellite-based forest monitoring, paired with other sophisticated measures of a forest's health, is transforming the speed, precision, and economics of finding and eradicating infestations and pinpointing acreage where preventing wildfires and deforestation will prove most effective. Rather than rely on ground-based, manual surveys of vast tracts, forest managers are refining their ability to observe more useful data from space. As success stories pile up, however, the science still must rely on the political will to enact needed policies for a healthier climate and forests.

  • In a boon for the climate, philanthropists are making it rain for cleantech innovators

    Prime Coalition is financing clean tech startups and climate-focused technologies that often don’t get a lot of funding. These technologies can be expensive to build and don’t generate profits immediately. So far, the public charity has secured $89 million that it has given into 18 energy ventures. “What’s important here is that the climate crisis is such a large-scale problem that we need lots of different types of solutions,” says Sarah Kearney, founder of Prime Coalition, “and so we need to match up right-fit capital to each kind of solution.”

  • Chennai Ran Out of Water — But That's Only Half the Story

    The city of Chennai in India is engaging in wetlands restoration and stormwater management by using traditional knowledge and community action to reduce flooding and ensure that people have access to drinking water. Through a development program called Water as Leverage, they are implementing “slow water” projects that restore flow paths for water, which could provide greater water resiliency for humans and protect and restore natural ecosystems. While it can be difficult to get government engineers to embrace green solutions, public awareness of the environmental work is helping move the projects forward.

  • Should you recycle your disposable mask?

    A company known as TerraCycle recycles "items other companies won’t accept" – including the many masks, gowns, and gloves that have been used during the coronavirus pandemic. While the service is free for those who can access one of their ZeroWaste box locations, individuals must request and pay for a box if they wish to participate. Environmentalists say that there is still debate about "whether it’s more environmentally friendly to throw away masks or recycle them," the service itself helps "remind consumers and companies that trash doesn’t disappear after it’s thrown out."

  • A new era in maritime travel: Electric boats

    The Maid of the Mist has given tours of Niagara Falls for 174 years, and recently replaced its fleet with electric catamarans, the first of their kind in North America. The boats are zero-emission and run on dual banks of lithium-ion batteries that are recharged between each tour by plugging two high-voltage lines into a charging station for seven minutes. The charging station is powered by a nearby hydroelectric facility. Two joysticks, like those on an arcade game, allow captains to steer the boats and dual monitors in the wheelhouse provide detailed battery status reports for constant monitoring.

  • Saving Cape Cod's dolphins

    To prevent the mass stranding of dolphins on Cape Cod, staff and volunteers from the International Fund for Animal Welfare are utilizing technology to work efficiently and quickly to save these creatures. An app called Send Word Now helps coordinate their 220 rescue volunteers along the coast, which has led to an increased in dolphin survival rate over the years. In Wellfleet, researchers are using sound recording devices to listen to dolphin sounds, which can help predict if they’re about to strand and offers more time for first responders to help.

  • Colville, Washington Survived the Timber Wars. Now It's Tackling Wildfire

    A collective of timber companies, conservationists, and forestry professionals has made the adjacent national forest more resilient to wildfires by focusing on small-diameter trees while preserving old growth. In 2019, the Northeast Washington Forest Coalition allowed for the harvesting of 87.1 million board-feet from the forest and 16,561 acres underwent controlled burns and mechanical thinning to mitigate the risk of wildfires. The group’s record of compromise and innovation could offer a blueprint for other areas looking to boost the resilience of fire-prone forests and rural economies.

  • Cold Hard Cash for Your Greenhouse Gas

    Refrigerants being used in old air conditioners or grocery story cooling systems leak into the atmosphere contributing to global warming. Tradewater, a company in Illinois, picks up these containers, destroys the refrigerants, gives them cash, and then sells them as carbon offset credits. They collect up to 250,000 pounds of refrigerants per year, but there is still more out there. Supermarkets in the United States could switch to more natural refrigerants, but barely 1 percent are known to have done that. Getting rid of these refrigerants can be an important solution to combating climate change.
