Cellulosic ethanol land-use harms forests, environment, climate
David Schneider. "Loser: Grassoline's Dark Side." IEEE Spectrum. January 2010: "Carpeting the continent with enough switchgrass to displace all that petroleum use is theoretically possible—but it would be an environmental catastrophe on many counts. For one, it would devastate what’s left of the already besieged wilderness. And according to estimates that Timothy Searchinger of Princeton University and his colleagues published in the journal Science in 2008, it would also exacerbate the world’s greenhouse-gas problem, not help solve it. That’s because even if switchgrass agriculture were limited to established cropland, we’d end up having to convert forests and other land to agriculture just to feed ourselves. That in turn would release huge amounts of carbon dioxide into the atmosphere."
