why refresh it if you have nothing to say?

The reality is, water shortages is only one symptom of the real problem....too many people. There is a concept called "carrying capacity" , meaning how many people can an area support, given all the constraints. Once this is exceeded, natural laws will take over and correct the imbalance, and the laws don't care about who thinks they have 'rights'.

This happened in the cliff dwellings of the Anasazi indians a few hundred years ago, and it happened in the Sahara a few thousand years ago. We humans have the ability to control our population now, and plan for environmental problems....but somehow I doubt we will.
