Big oil hates ethanol, Sally Struthers hates ethanol and as far as I am concerned, some self-righteous ultra tree-huggers will not be satisfied until automobiles no longer exist.
That article is incredibly vague.
If I didn't wear a tin-foil hat, i'd almost be inclined to wonder if "Big Oil" funds some of these studies that yield Ethanol Hate Headlines.
Did anyone know that prior to prohibition, ethanol and alcohol fuels were much more prevalent in this country? John D. Rockefeller's (of Standard Oil) support of alcohol prohibition helped quash alcohol fuels.
