"American agriculture is badly in need of diversity. Another threat to the food system of course is the likelihood that petroleum is not going to get any cheaper."

Next Quote

The passive American consumer, sitting down to a meal of pre-prepared food, confronts inert, anonymous substances that have been processed, dyed, breaded, sauced, gravied, ground, pulped, strained, blended, prettified, and sanitized beyond resemblance to any part of any creature that ever lived. The products of nature and agriculture have been made, to all appearances, the products of industry. Both eater and eaten are thus in exile from biological reality.

— Wendell Berry
