These so called food based biofuels can actually hurt the environment if they are produced on land that was formerly grassland rainforest or savanna the scientists said in the journal Science. Nonfossil fuels ethanol made from corn or sugarcane and biodiesel made from palm trees or soybeans are meant to lessen dependence on petroleum products which release the greenhouse gas carbon dioxide when they burn. However biofuels can release carbon even before they are burned depending on how they are made said study co author Jason Hill of the University of Minnesota. As demand for these alternative fuels grows farmers are plowing under forests and grasslands that used to store carbon and keep it from getting into the atmosphere and using these lands to grow the food crops that now can be used for ethanol or biodiesel. Biofuels grown this way come with a carbon debt the researchers found. Instead of cutting greenhouse pollution t! he net effect is to increase it. The carbon lost by converting rainforests peatlands savannas and grasslands outweighs the carbon savings from biofuels. Some conversions release hundreds of times more carbon than the annual savings from replacing fossil fuels. CENTURIES OF CARBON DEBT Continued.
