"Modern industrial agriculture has been described as a method of using soil to turn petroleum and gas into food." "Approximately 1,500 liters (350 gallons) of oil equivalents are required to feed each person in the United States each year, and every calorie of food produced requires on average ten calories of fossil-fuel inputs. This is a food system profoundly vulnerable, at every level, to fuel shortages and skyrocketing prices. Both are inevitable."
