yes it IS a waste of food, in the fact that a lot of farmers that used to produce corn for human consumption now produce corn intended for ethanol which in turn makes what corn is left for consumption more expensive... or are you trying to say farmers didn't switch cropsIt’s a fact. They do use “feed corn” for ethanol. Meaning corn used to produce food for cattle, hogs, chickens, ducks whatever. And animal feed has increased substantially because of the use of corn for ethanol. So, guess who pays for the increase?
Also, and this is a local observation, many farmers here have switched from soybeans and cotton to corn for ethanol. Guess what that does to soy products and cotton products?
They switched from white, human-edible corn to yellow field corn.
