A new study will be released showing that biofuels actually create more greenhouse gases (GHG) rather than offset GHG from fossil fuels. Biofuels have been heralded as the way to reduce GHG emissions and reliance on foreign oil. However, it does not have the environmental benefit as originally thought and it is creating a problem in food supply. Crop land is being diverted to produce heavily subsidized biofuels, like corn ethanol. A good article in IHT gives a good account of the issues. The study it refers to is from the journal Science and is titled "Land Clearing and the Biofuel Carbon Debt" if you have access to the journal somewhere.
Biofuels are a product of our thought process when trying to solve problems. We are not looking at the cause but the effect. We, as citizens of the world, need to start making our voices heard and being the catalyst for change.
