See this link http://www.iceagenow.com/US_Food_Supplies.htm. If a severe drought hits the Midwest on a scale like that of the 1930s, there is no slack in the food supplies and no storage to draw upon because dumbass politicians decided that taxpayers shouldn't fund the storage of grain and agribusinesses that do 99 percent of the farming with 1 percent of the population do not CARE.
