Well, there's a problem with this, folks.
It's pretty well established that ethanol's less efficient than gasoline; for the record, I myself use 100% pure gasoline.
The primitives seem to think that if the grain and beans currently used for ethanol were used instead to feed the hungry, all would be okay. The primitives are wrong.
The reason grain and bean prices are so high right now is the demand for them in the manufacture of ethanol.
If there was no demand created by the ethanol industry, that does not necessarily mean farmers will keep growing grain and beans, this time to feed the hungry. Many of them might choose to grow nothing at all.
Ethanol's putting money into the wallets of farmers, but it doesn't follow that if such crops were converted for human consumption, that the farmers would grow it, or as much of it.
