Conventional agriculture pollutes our water, is a major contributor to climate change and has degraded soil carbon by as mush as 80 percent in most of the world's breadbaskets. Created by burning biomass in the absence of oxygen, biochar has the unique ability to withhold carbon from the atmosphere while simultaneously building soil fertility. Author Albert Bates traces the evolution of this extraordinary substance from the ancient dark earths of the Amazon to current practices.
