Breaking the Link between Food and Biofuels
探讨美国、欧洲和南美生物燃料扩张与粮食价格上涨的关联，指出生物燃料原料多来自可食用作物或占用可耕地，质疑其合理性。
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.
