Biofuels, fuels made from biological sources, are highly controversial. One of the most significant but highly debated critiques of biofuels is the "Food vs. Fuel" idea. "Food vs. Fuel" proponents claim that by using food resources and taking up land that might be used for food production or natural vegetation, biofuels harm the environment and the most vulnerable at the same time. In the first half of this class we will go through the facts on the current state of biofuels in the world today and lay out the ways in which current biofuels technology (corn ethanol, sugarcane ethanol, etc.) affects food resources. In the second half, the two teachers will make the case for their differing views on the subject.
