That is the title of an article you can read here. In one of my classes this week, we read about ethanol in the book The Economics of Public Issues. This article talks about the environmental problems that biofuel crops might cause. Here is the first paragraph:
"Just one month ago, a study conducted by a team of American researchers concluded that there was nothing more environmental-friendly than the biofuel crops, that could reduce the greenhouse gas emissions by 94% and produce five times more energy. New studies however warn that by transforming the various ecosystems into biofuel crop fields would only accentuate the global warming phenomenon rather than reducing it. According to the latest estimations, converting natural ecosystems into biofuel crop fields is likely to release up to 420 times more carbon."
