Mollison, Bill
Permaculture: A Designers' Manual
Tagari Publications, 1988

This is the bible for living a life that makes ecological sense, one that is consequently conducive to peace through cooperation. Mollison not only focuses on the specifics of natural systems, in all types of climates, and how we can successfully interact with these bodies of trees, water, soils and more, but he also discusses patterns in nature and how they can inform us in our own design of human communities.

Van Der Ryn, Sim, and Cowan, Stuart
