An entertaining and enlightening exploration of why waste matters. The Origin of Feces takes an important subject out of locker-rooms, potty-training manuals, and bio-solids management boardrooms into the fresh air of everyone's lives. With insight and wit, David Waltner-Toews explores what has been too often ignored and makes a compelling argument for a deeper understanding of human and animal waste. Approaching the subject from a variety of perspectives--evolutionary, ecological, and cultural--, The Origin of Feces shows us how integral excrement is to biodiversity, agriculture, public health, food production and distribution, and global ecosystems. From the primordial ooze to dung beetles, from bug frass, cat scats, and flush toilets to global trade, pandemics, and energy, this is the awesome, troubled, unexpurgated story of feces.
