A powerful tool for curbing climate change is right beneath our feet. Carbon farming represents a paradigm shift. The program introduces farmers in the U.S. and Japan who employ this method of regenerative agriculture. Instead of tilling the soil and spreading chemicals, they let organisms in the ground do the work. Carbon creates good soil, looking something like chocolate cake. The approach harnesses the power of nature, with twin goals of capturing carbon from the air and producing nutritious organic food.
