Origin of Feces [EPUB ebook] 
What Excrement Tells Us About Evolution, Ecology, and a Sustainable Society

The Origin of Feces takes an important subject out of locker-rooms, potty-training manuals and bio-solids management boardrooms, bringing it into the fresh air of everyone’s lives. With insight and wit, David Waltner-Toews explores what has been too often ignored as he makes a compelling argument for a deeper understanding of waste. Waltner-Toews shows how integral excrement is to biodiversity, agriculture, public health, food production, food distribution and ecosystems. It serves as a reminder that unless we change how we think about shit, we are doomed to live in it.
