The Environmental Costs of Corn-Based Ethanol

In 2007, Congress passed a law requiring gasoline to be mixed with ethanol, to reduce dependence on foreign oil and promote environmentally friendly biofuels. Corn is the primary source of ethanol in the United States, and this, ironically, has turned out to have devastating consequences for the environment. In response to rising demand for corn, American farmers are converting environmentally valuable grasslands into corn fields. Five million acres of conservation land have disappeared while Obama has been in office. To put that into perspective, that’s more than the Yellowstone, Everglades and Yosemite National Parks combined. In 2010, for the first time, fuel was the number one use for corn in America, which means agricultural subsidies are now in large part being used to subsidize our energy needs rather than food.
