"A 2008 study published in Sciencemagazine found that corn-based ethanol increases greenhouse gas emissions instead of reducing them. A 2009 study concluded that plowing fields to grow corn for ethanol could release more carbon dioxide into the atmosphere than ethanol offsets."
"Ethanol has fallen out of favor largely because it eats up so much of the corn supply. Some 40 percent of the U.S. corn crop goes into gas tanks, not stomachs. As demand for corn has risen, so have food prices. As the cost of feed has risen, so have beef prices. ActionAid USA and other anti-poverty groups also oppose ethanol supports."
