The problem here is that McCain is trying to say that Obama is a one trick pony when it comes to the energy debate.

No one is saying that we should replace gasoline with ethanol. It is something that can be used to add to the gasoline, spreading out the current supply, lessening the demand.

The problem on the McCain side is that once the wells are drilled the environmental damage is done and pretty much can't be undone. The wells sometimes come up dry, and it leaves us in the hands of people who have demonstrated a great ability to manipulate the market.

At least corn, hemp, soybeans, etc. can be grown and regrown to produce both oil and ethanol.

As far as the rest of the world starving, I'm trying to not be shallow about it but how is it that these folks survive in a nation/country/state/continent that apparently can't support it's population? Is it only the United States that can grow crops and feed itself as well as the rest of the world?

If so, along with the U.S. cutting back on it's consumption, shouldn't the rest of the world be putting pressure on the other countries that are heavy consumers of petroleum resources (China and India to name just two others) so that we don't have to use cellulosic ehtanol / bio-diesel?

Shouldn't the rest of the world be putting pressure on the oil rich nations to stop screwing with the world economy and food supply?
