Don't suffer biofuels gladly | Gristmill: The environmental news blog | Grist

Well, that's what a coalition of green NGOs -- Environmental Working Group, Friends of the Earth, Network for New Energy Choices, the Clean Air Task Force, and New York Public Interest Research Group -- are calling for with regard to the nation's biofuel policy.

They charge that the U.S. biofuel program actually "exacerbates global warming" because of greenhouse gas emissions from nitrogen fertilizers and the conversion of grasslands and rainforest to cropland. Further, the mass production of monocropped fuel feedstocks like corn, soy, and palm degrades soils, increases water pollution, drives out biodiversity, and endangers the food security of vulnerable populations. In the process of creating these lamentable side effects, biofuels are offsetting a relatively small amount of conventional fuel use -- and are grabbing the lion's share of federal support for alternative energy. In short, biofuels have been an abject failure.
...
After all, as Dennis Keeney, emeritus professor of agronomy at Iowa State, recently wrote, "money, not science, has driven ethanol fuel policy." Keeney's assessment applies to U.S. biofuel policy since its inception under Jimmy Carter.
