Environmentalists Debate the Promise of Biofuels

Via NPR's Science Friday (with audio):
Two recent studies published in the journal Science suggest that growing additional biofuel crops might actually increase the amount of carbon entering the atmosphere, especially if existing forests or grasslands must be cleared for biofuel farming. Do the fuels make sense from an environmental and economic standpoint?

When U.S. politicians talk about biofuels, most of the time they are talking about ethanol made from fermenting corn. However, there are many other types of biofuels, including biodiesel from algae and cellulosic ethanol technology. Experts discuss various approaches to biofuels and the advantages and disadvantages of each.
