"Mandating the Impossible (Not to Mention the Stupid)"

Here.

Excerpt (see the post for links):

The Congress is demanding 36 billion gallons of ethanol. Presumably, this is all from domestic sources because Congress has refused to drop the enormous tariffs on ethanol imports. But the entire corn harvest in 2004 of 11.8 billion bushels would make only 30 billion gallons of ethanol. So Congress wants us to put ALL of our food supply into our cars? Maybe we can tear down the Amazon rain forest to grow more.
