“Cultivated biofuel crops may actually increase the carbon emissions that ethanol and other biofuels were supposed to reduce. Plowing up rainforests, peatlands, savannas and grasslands to plant corn, sugarcane and other crops for biofuel releases 17 to 240 times more carbon than the annual savings from replacing fossil fuels.
That’s because the plants and soil are a giant carbon-storage system. During cultivation, the carbon escapes as carbon dioxide. The studies are the latest warning against an all-out rush into corn ethanol at the expense of food for humans and tilling of uncultivated ground.”
