[Mr. Lucky]

Increased production doesn't result in increased cultivation, just the opposite.

My best corn ground came in at over 200 bushels per acre last year. The ground was cultivated far less to produce that crop than it was 75 years ago when my grandfather was happy with a yield of 25 bushels per acre.

And if we want to replace gasoline with ethanol, we'll have to get that 200 bushels per acre up to 800 or so, or we'll need a strain of corn that will yield four times the potential energy of what we have now.

Soil depletion would be inevitable.

Bio fuels simply cannot replace crude oil as a fuel.
