Four of every 10 rows of U.S. corn now go for fuel, not food.

Wall Street Journal - The global economy is getting back on its feet, but so too is an old enemy: food inflation. The United Nations benchmark index hit a record high last month, raising fears of shortages and higher prices that will hit poor countries hardest. So why is the United States, one of the world's biggest agricultural exporters, devoting more and more of its corn crop to . . . ethanol?

The nearby chart, based on data from the Department of Agriculture, shows the remarkable trend over a decade. In 2001, only 7% of U.S. corn went for ethanol, or about 707 million bushels. By 2010, the ethanol share was 39.4%, or nearly five billion bushels out of total U.S. production of 12.45 billion bushels. Four of every 10 rows of corn now go to produce fuel for American cars or trucks, not food or feed. This trend is the deliberate result of policies designed to subsidize ethanol. Note the surge in the middle of the last decade when Congress began to legislate renewable fuel mandates and many states banned MTBE, which had competed with ethanol but ran afoul of the green and corn lobbies.

Corn ethanol's downsides: High food prices, more pollution
