The Washington Post ran an article yesterday in thier Outlook section about "The Negligible Benefits of Ethanol, Biodiesel." The authors are discussing the article today here. Check it out.
David Tillman and Jason Hill wrote it -- Tillman is "an ecologist at the University of Minnesota and a member of the National Academy of Sciences. Jason Hill is a research associate in the Department of Applied Economics at the University of Minnesota."
Also, last Friday the BBC reported that "Biofuel demand makes food expensive." It's a brief article; go forth, check that out too.

Well, I have read almost the same statement before (don't remember the author, title was «Biofuels: green or gray?»). The article raised questions whether the impact of the biofuels planting is very harmful or not, and the author concluded that other, more efficient plants or technologies are welcome.
In this case, the authors show an example of a more productive and more environment friendly method of planting.
