I think that's right. Some of the most intelligent people I've ever met are farmers. If they're not very intelligent and don't have good business savvy, then they don't stay in business. You're absolutely correct.
The question is this. The growing of food crops is probably always going to be more valuable than the growing of ethanol crops. It will depend on the market.
Of course, one of the things that's driving ethanol production at the moment is the subsidies for ethanol. Certainly, there are tremendous subsidies on producing ethanol in the U.S.A. If you remove those subsidies, most farmers will go back to growing grain for food.
Yes, there is a problem. I think food crops will always be more economically viable than crops that are grown for ethanol. They will have to be pushed to the sidelines of agriculture. I agree with you that it's a problem.
I think the competition between food and ethanol, certainly in the U.S.A., is a problem that people are now talking about. It has to be resolved in some way.
