I say you don't have a clue. Food grade corn is not used to make ethanol. The price paid to the farmer for food grade corn is 70cents to 90cents above the price paid for #2 yellow corn (which is what ethanol is made from when corn is used). There will not be a shortage of food grade corn for this very reason. That and the fact that there aren't that many more ethanol plants on-line now than 5 years ago. The number of corn acres has been increasing for the last 2 years. Carryout (grain left in storage) hasn't changed. The price paid to the farmer/rancher for live cattle is nearly the same as it was in the late '80's and early '90's when the price of corn was less than $3 per bushel. Explain that to me.
BTW Dick tater, what would YOU do to increase fuel production? Would you allow more exploration and recovery of oil/natural gas from our own country? What are you doing to try to produce a form of fuel to power vehicles? Get off your high horse. Lead, follow, or get out of the way!
EDIT: Using corn for ethanol is just a first step. Ethanol producers realize there are better sources. Using corn to get plants up and going is simply the easiest way to start. When other sources become economically feasible, plants will switch over, But, understand, that some crops will not grow throughout the entire country. Corn will.
