It's another pro-ethanol paper. There's several things I have problems with.

Soil erosion is second only to population growth as the biggest environmental problem the world faces. Yet, the problem, which is growing ever more critical, is being ignored because who gets excited about dirt?

[Corn-derived ethanol] collects too little energy for all the investments of energy we have to use to produce it.

It would help agriculture (if it were).

If ethanol is so great, why are we spending $3 billion in subsidizing it?

Erosion is a slow and insidious process. Yet, controlling soil erosion is really quite simple: The soil can be protected with cover crops when the land is not being used to grow crops.
