I thought this Wall Street Journal Blog post was very interesting. Apparently, biofuels may not be such a good idea after all as scientists are beginning to believe that they actually increase greenhouse gases.

Some recent academic studies have argued that biofuels actually cause more greenhouse-gas emissions because they lead to destruction of carbon-rich forests. Environmental groups like Greenpeace that campaign against biofuels applauded Dr. Watson’s comments. But the jury is still out: Many leading biofuel scientists question new studies that say biofuels have a much bigger carbon footprint than fossil fuels.

The scientific back-and-forth is starting to shape policy—in Europe at least. European officials have tried to limit the import of biofuels that cause forest destruction. Earlier this month, the European Union said it would stop subsidizing many local biofuel crops, like sugar beets.

It cracks me up that we rushed into public policies to promote biofuels without actually taking the time to determine that they just made the situation worse while at the same time burning up all of our food. It's just crazy!
