Expansion of biofuel production in the United States, Europe, and South America has coincided with recent sharp increases in prices for food grains, feed grains, oilseeds, and vegetable oils. It is only natural then to associate high food prices with expanded biofuel production. The credibility of this association is heightened by the fact that practically all biofuels in the world are produced from feedstocks that could be used to produce food or that are produced on land that could produce food.
