IceMan, your replies well said, that's what I was getting at. For every acre of feed corn grown for Ethanol is one less acre used for real food. Not to mention all the fresh water used and the oil required for fertizer, pesticides and transport.
There is a simple equation in the universe. Energy is never lost or gained, it's just transfered.
Cleaner burning ethonal fuel will be offset by the fossil fuels farm machinery will use, fertilizer, transportation, consumption of fresh water ect...
There is always something on the other side of the equation! People believe electric cars are the solution. Hate to break the news to you but if the pollution isn't coming out the tail pipe it's coming out the smoke stack of a coal plant. Wait a minute we can use Nuclear to get the electricity to charge our batteries....did anybody consider how we'd handle the extra thousands of tonnes of nuclear waste that would incure should every car in the US become electric?
There is only 1 way to reduce pullution in this world and that is to reduce the energy we use....and how do you reduce the energy we use.... cut it off at the source that consumes it...population control.
