Biofuels Promoters Warn of Unexpected Consequences

A new study by a Minnesota-based agriculture think tank finds that growing crops to make gasoline is having unexpected consequences. Ben Lilliston is with the Institute for Agriculture and Trade Policy. He said growing corn for ethanol production is reducing the diversity of crop rotation and threatening wetlands. Lilliston said the report doesn't oppose the continued manufacture of bio-fuels and ethanol but that more money has to be put into government programs to protect growing areas.
