  • The lost generation of ancient trees

    Ancient trees like the Big Belly Oak, which grows to be hundreds of years old, provide substance to thousands of invertebrate species, and hundreds of species of lichen and fungi. However, due to changes in forest management and agriculture, many of the ancient trees are not surviving long enough to age. It's crucial for them to age because that's when many species of fungi and insects begin to move into their core. In order to speed up the aging process scientists are trying two methods, veteranisation and inserting fungi into trees.

  • Fridge detectives

    In the first half of this episode, the producers discuss "Tradewaters," an organization that disposes of canisters inside refrigerators. These canisters hold potent greenhouse gases. One 30-pound canister can leak up to 131 tons of Co2, or a year's worth of driving for 54 cars. The organization disposes of thousands of canisters across Central America, Chile, South Africa, and India. The practice of disposing of these canisters saves between one to two percent of global Co2 emissions, according to estimates.

  • France's 'Peevolution' Is Irrigating Farms With Liquid Gold

    Getting rid of urine is very wasteful, in the European Union alone almost 6,000 billion liters of water are used to flush urine. TOOPI Organics is using urine as a resource. Founded in 2019, the biotech company collects urine and using a fermentation process transforms it so it can be used as a fertilizer. Its urine fertilizer helped plants grow 60 to 110 percent more than a traditional mineral fertilizer. Its factory in the city of Bordeaux is able to produce 2,500 liters of organic fertilizer per day.

  • Virginia project helps low-income homeowners ditch fossil fuels

    Two organizations partnered to help eight low-income households convert their homes to become all-electric in Virginia. It entailed replacing fossil-fuel based heating and cooling systems like stoves and water coolers with electric ones. Some of the households saw a reduction in their utility bills. Organizers estimate that over the course of 20 years the changes will result in the households avoiding the emission of over 2 million pounds of carbon dioxide.

  • How Clayoquot Sound's War in the Woods transformed a region

    Tofino, a popular tourist destination in Clayoquot Sound, a region on the west coast of Vancouver Island, attracts about 600,000 annual visitors. The Tla-o-qui-aht First Nation and other Nuu-chah-nulth nations have created an eco-based tourism market. They are trying to restore the area after it was decimated by decades of logging in the area. The five central Nuu-chah-nulth First Nations took over tree-farm licenses and created Guardian programs, as well as restoration and monitoring projects. Tofino's tourism generated $250 million in profits, setting up a model that could be used by other First Nations.

  • How Ex-Miners Turn Toxic Land into Lavender Farms

    Appalachian Botanical Company, or ABCo, owns a lavender farm that rests on a retired coal mine. The farm aims to restore the land and soil by growing lavender. Coal companies are legally obliged to restore the land they have mined, known as reclamation. ABCo is part of the reclamation. However, they also want to restore the community, it employs former coal miners and recovering addicts to harvest, pick, distill, and package the flowers. The farm grew two-fold since its inception.

  • Meet the Cheakamus, the only community forest to develop carbon offsets in B.C.

    The Cheakamus forest, which spans 33,000 hectares, is a community run forest, managed by the two First Nations and the city of Whistler, in British Colombia, Canada. By not logging massive amounts of wood, the forest keeps 15,000 tons of carbon dioxide out of the atmosphere per year, the equivalent of the total emissions produced by 773 Canadians. The partners then sell those carbon offsets, generating about $100,000 in annual revenue a year. The move is one being done by community forests around the country and can provide an example of climate-based solutions that are economically beneficial.

  • Why these farmers are welcoming muskrats, birds, and snakes

    In Canada, farmers are rewilding their farmlands, a process where a farmer restores their habitat to a more natural state. It includes things like planting trees, building hedgerows, and creating ponds. Rewilding can prevent soil erosion, carbon sequestering, and filtering water, among many other things, reversing some of the adverse effects caused by farming. One non-profit, the Alternative Land Use Services is funding these rewilding projects by paying farmers. ALUS projects span 31,000 across Canada.

  • Evidence Indigenous burning works is growing. Could Australia offer a model for B.C.?

    A review of 120 years of data found that traditional indigenous fire burning practices, which are low-intensity and controlled, lead to an increase in biodiversity. The practice has been done for years in indigenous communities to clear forage space, stimulate growth, or clear waterways. In Australia, where the practice has wide support, traditional low-intensity fires have led to a reduction in the intensity of large wildfires. They have also reduced and methane and nitrous oxide emissions by close to 40 percent. Other countries like Canada face hurdles to implementing the practice on a wider scale.

  • PA cities have a sewer-system problem. Green infrastructure can help — but comes with its own risks

    In many cities, rainwater is drained through "grey infrastructure" things like pipes, streets, etc. In some cities, this system is combined with the sewage system. Rainwater drains into the sewage system, is then cleaned, then emptied into the river. However, with strong storms some sewage systems overflow. A problem that will worsen with climate change. In Harrisburg, Pennsylvania, rain gardens are one solution to overflowing sewage systems. Cities like Harrisburg are turning to green infrastructure, things like rain gardens, roofs with gardens, and parks, to ease the burden on gray infrastructure.
