A recent report issued by the European Union has revealed that biofuels, or fuel made from living, renewable sources, is not really all that beneficial to the environment. Rather than reduce the net carbon footprint as intended, biofuels can produce four times more carbon dioxide pollution than conventional fossil fuels do.
Common biofuels like corn ethanol, which has become a popular additive in gasoline, and soy biodiesel, which is being used in commercial trucks and other diesel-fueled vehicles, are often considered to be environmentally-friendly because they are renewable. But in order to grow enough of these crops to use for both food and fuel, large swaths of land around the world are being converted into crop fields for growing biofuels.
In other words, millions of acres of lush rainforests are becoming corn and soy fields in order to provide enough of these resources for their new uses. The net carbon footprint of growing crops for fuel is far higher than what is emitted from simple fossil fuel usage.
