The law of unintended consequences has reared its ugly head once again, with a study published in the Feb. 7 issue of the journal Science.
Environment: In 2005, America used 15% of its corn crop to replace just 2% of its gasoline. Two new studies say use of biofuels will leave the world a warmer and hungrier place.
According to University of Minnesota ecologist and study co-author David Tilman, converting the grasslands of the U.S. to corn for ethanol releases excess CO2 emissions of 134 metric tons per hectare (equal to 2.47 acres).
The reason is that plants, from grasses to trees, store carbon dioxide in their roots, shoots and leaves.
"I know that when I look at a tree that half the dry weight is carbon," says Tilman. "That's going to end up as carbon dioxide in the atmosphere when you cut it down."
"Any biofuel that causes land clearing is likely to increase global warming," says Nature Conservancy ecologist Joseph Fargione, the lead author of a second study also published in Science.
