The Pleasures of the Flesh: If you care about hunger, eat less meat.

"The World Bank points out that “the grain required to fill the tank of a sports utility vehicle with ethanol … could feed one person for a year”(5). Last year global stockpiles of cereals declined by around 53m tonnes(6); this gives you a rough idea of the size of the hunger gap. The production of biofuels this year will consume almost 100m tonnes(7), which suggests that they are directly responsible for the current crisis."
