Probably someone has posted to this topic but I have not seen it so, here goes. I was listening to NPR yesturday and there was a piece on world struggles and they were saying that when it all shakes down the next world confrontaion will not be about food or fuel but about water. I have always wondered if water was finite. Means is there only just so much, has only ever been just so much and if that is the case. How about the big corporations buying up third world countries water supplies bottleing them and selling them to us so that those countries can make some money but then the farmers there can't grow food because the water table is so depleted. I just wonderedif any here have thought about this.
