Corn prices have double do to corn ethanol demands. U.S. farmers are planting more corn. They aren't doing it organically. They're using nitrogen fertilizers. The runoff is increasing. Millions of pounds (210 estimate) is ending up in the Gulf of Mexico over a year. It adds hugely to a dead zone of 7,000 to 8,000-plus square miles. So the farmers make more money growing more expensive corn while the fishers in the Gulf lose more and more and the environment suffers more and more while ethanol is supposed to be better than gasoline. As we said long ago, corn-ethanol fuel is stupid.
That doesn't even say anything about how the corn isn't feeding hungry people and how hungry people can't afford corn food products so easily anymore. Corn tortillas have been a staple in Mexico for instance.
Also, the whole nitrogen fertilizer production cycle is itself fuel intensive.
There just isn't anything good to say about this whole system.
