Albert Bates, an influential figure in the intentional community and ecovillage movements discusses his new book "The Post-Petroleum Survival Guide and Cookbook: Recipes for Changing Times." Over the coming years we will need to move from a global culture addicted to cheap, abundant petroleum to a culture of compelled conservation, whether through government directive or market forces. Bates takes a positive, upbeat, and optimistic view of "the Great Change," promoting the idea that it can be an opportunity to redeem our essential interconnectedness with nature and with each other. Bates is a lawyer, author and teacher. He has been director of the Institute for Appropriate Technology since 1984 and of the Ecovillage Training Center at The Farm in Summertown, Tennessee since 1994.
