George W. Bush diverted more than a quarter of the total U.S. grain crop into ethanol, enough to feed 330 million people for one year and raising food prices worldwide.

If the entire U.S. grain crop were converted to ethanol (leaving no domestic crop to make bread, rice, pasta, or animal feed for meat, milk, and eggs), it would satisfy at most 18 percent of automotive needs.
