My concern with the environmental issues of ethanol are not necessarily related to what comes out of the car's tailpipe.

I am more concerned with the emissions resulting from the growing of the corn, the harvesting of the corn, the processing of the corn, the distillation of the ethanol, and the transportation of all that stuff.
That process is net negative energy.
It takes more energy to produce ethanol than you get from the ethanol produced.

How could that possibly be considered environmentally friendly?
