Most Western farm systems rely heavily on cheap fossil fuel to cultivate, processes, store, package and get crops to market. While organic producers use almost half the energy that conventional producers use for cultivation (through the elimination of artificial fertilizers and pesticides) most rely on fossil fuel powered mechanical cultivation and harvest methods. Canadian organic producers supply approximately 30 per cent of the domestic market so large quantities of organic food are imported from south of the border, eliminating any energy savings provided by organic cultivation and management. - From Proximity & Petroleum by Derek Masselink
