Smithsonian scientists highlight environmental impacts of biofuels

Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production. Corn, soy and sugarcane come up short. The authors urge governments to be far more selective about which biofuels they support, as not all are more environmentally friendly than fossil fuels. Because fossil fuels contribute to global warming and supplies are dwindling, more eco-friendly alternatives are required.
