A few years ago, my wife inherited a share in a piece of farm land in Kansas. It was willed to a group of cousins, one of whom actually farms the land. She receives a yearly check for her share of the proceeds (a nominal amount, true, but much better than a boil on the butt!). Along with the check, she gets a lot of agricultural bulletins. The following is an excerpt:

"The Ogallala Aquifer of the central United States is one of the world's great aquifers, but in places it is being rapidly depleted for growing municipal use, and continuing agricultural use. This huge aquifer, which underlies portions of eight states, contain primarily fossil water from the time of the last glaciation. Annual recharge, in the more arid portions of the aquifer, is estimated to total only about ten percent of annual withdrawals."

What happens to our food supply if the aquifers used to irrigate agricultural land all go bye-bye?
