I don't know how much corn is grown under irrigation. I do know that widespread water shortages could become a much bigger issue than oil shortages.

Canadian moonbats have been ringing alarm bells for decades about large-scale shipments of water to the U.S. The politics around any move toward a Continental water strategy would be messy, to say the least.

You could pipe water from Alaska of course -- but, that would take some energy. Similarly, you could get into large-scale desalination -- but that's also an energy hog. It would clearly make little sense to use energy to create water for irrigation of land -- in order to grow energy crops.

My guess is that LESS than 1% of the corn in the 4 major corn growing states is grown under irrigation.

Iowa, Illinois, Ohio and Indiana are primarily dry land farming states. There are a few exceptions along the Mississippi river where the soil is sandy and won't hold moisture.

So to suggest that growing corn will deplete the aquafers is simply NOT the case in the major corn growing states.
