A piercing, impassioned guide to living a truly responsible life on earth. Human waste, once considered a gift to the soil, has become toxic material that has broken the essential cycle of decay and regeneration. Here, writer Derrick Jensen and activist Aric McBay weave historical analysis and beautiful prose to remind us that life--human and nonhuman--will not go on unless we do everything we can to facilitate the most basic process on earth, the root of sustainability: one being's waste must always become another being's food.--From publisher description.
