Can Dirt Save the Earth?


One tactic for combatting climate change has to do with soil health. Soil can withdraw and store carbon from the atmosphere—at a higher rate when covered by manure—and also supports long-term soil sustainability and saves farmers money. Because agriculture already consumes much of the world's surface, proponents of carbon farming envision a world where large swathes of land act as a carbon sink. Potential drawbacks and things left to explore include how to produce compost without creating more energy than it saves and how to use cows effectively when they also contribute much of the carbon in the atmosphere.
