British author James Bruges directs our attention to biochar, finely ground charcoal used as a soil amendment. He discusses its benefits in reducing carbon dioxide in the atmosphere. Using the experiences of farmers in India who found that it was an incredibly effective, long-lasting fertilizer, he advises that this may be the way to solve the world’s major problems of generating sufficient crops as well as providing one solution to global warming. This work includes examples of biochar’s use around the world and scientific explanations for its success.
