Corn prices worldwide have increased by 50 percent over the past year. John Sununu, a Republican senator opposed to farm subsidies, says corn prices have risen in part because America is using increasing amounts of corn to produce fuel for automobiles.

"When you're diverting a third of the [corn] crop to ethanol it has a real impact on prices," said Senator Sununu. "To produce a gallon of ethanol takes 1700 gallons of water. Thirty million acres of land, going to produce the corn for ethanol."

This equation will never work, as long as we're 6,6+ billion people who want to live the lifestyle we do in the West. We could turn tampons, diapers, excrement, TVs and poll booths into fuel; we're still overcrowded on this planet of limited resources. If 5 billion people suddenly were turned into earth, we could use this to grow flowers instead and stop worrying about this problem in the first place.
