A balanced assesment of ethanol fuel

This article is one of the fairest pro and con discussions I have seen. It looks at arguments from all sides of the issue.
New Rules Project - Ask Dr. Dave:
"Fuel ethanol has many critics. Some are concerned that we may end up feeding our cars at the expense of our stomachs. That is a legitimate, although by no means an inevitable problem. When ethanol is made from corn, for example, as noted above, it is made from the corn starch. The plant's protein content is untouched. Indeed, the resulting product concentrates the protein. That product, called distiller's grain, is a high-grade animal feed. It often displaces corn itself. The world does not suffer from a shortage of starch or sugars."
