Farmer and environmentalist Wendell Berry is known to many as the father of the sustainable food movement. He is an outspoken advocate for an agrarian revolution to end industrialized practices that he says are poisoning the land and destroying rural communities. In recent years Berry has promoted a 50-Year Farm Bill, which presents a long-term plan to reduce soil erosion and land pollution by replacing annual crops with perennials. His latest book, Distant Neighbors, chronicles his 40-year correspondence with poet Gary Snyder, and discusses everything from faith and family to the destruction of the environment. Berry stopped by KQED and I had a chance to speak with him about agricultural policy and current trends in the sustainable food movement.
