In what may be his boldest and most controversial book, Paul Shepard presents an account of human behavior and ecology in light of our past. In it, he contends that agriculture is responsible for our ecological decline and looks to the hunting and gathering lifestyle as a model more closely in tune with our essential nature. Shepard advocates affirming the profound and beautiful nature of the hunter and gatherer, redefining agriculture and combining technology with hunting and gathering to recover a livable environment and peaceful society.
