I have long been thinking about problems like this.In both food and other shortages.Farmers growing grain for Ethanol instead of for food. The fact that we refuse to drill in places we know there is oil like offshore and places in Alaska. We have to balance conserving nature with the pressing need for oil. They say it's to expensive to drill for oil, Well look at the price on the gas pumps.It's time to start drilling and refining. Then maybe we can tell the Arabs where they can stick theirs. Our farmland is not being used in it's fullness. When I was a teenager, in the summertime every field was full of corn,oats, soybeans,peanuts, tomatoes,sweet potatoes and etc. Now in the farm areas you can drive for miles and see nothing but empty fields. Time to take an inventory of our priorities....
