Corn

Ethanol won't save us from oil dependence—or climate change.

The fact that corn-based ethanol is renewable doesn’t make it sustainable. When will presidential candidates stumping in Iowa admit as much?

A new survey reveals that biofuel crops have expanded onto millions of acres of new land, with serious consequences for the environment.

It may be better than the alternative, but it’s entirely disingenuous for producers and consumers to justify eating grass-fed beef on the essentialist grounds that it was “meant to be” that way.

Even as corn prices rise with the demand for biofuels, a simmering dispute percolates in Mexico where genetically modified imports from the U.S. are both welcomed and damned.
