Ethanol Production Wastes Corn - NYTimes.com

Even in a crowd of rising food and commodity costs, corn stands out, its price having doubled in less than a year to a record $7.87 per bushel in early June. Booming global demand has overtaken stagnant supply.

But rather than ameliorate the problem, the government has exacerbated it, reducing food supply to a hungry world. Thanks to Washington, 4 of every 10 ears of corn grown in America — the source of 40 percent of the world’s production — are shunted into ethanol, a gasoline substitute that imperceptibly nicks our energy problem. Larded onto that are $11 billion a year of government subsidies to the corn complex.
