Our world runs on fossil fuels. Annual production of usable, recoverable oil will drop to half of the peak amount around 2030. The social effects will include crime, cults, craziness, and chaos. "Peak oil," however, basically means "peak food." Those who survive will be those who have mastered the art of subsistence farming. -- Peter Goodchild, author, "Tumbling Tide: Population, Petroleum, and Systemic Collapse" -- prjgoodchild@gmail.com
