Water Crisis

I am not a prophet who can predict the future. But in year 2010, we will have a water crisis. Forget about higher price of Petroleum and other energy sources. Human Being cannot live without water. Our ancestors survived for thousand years without the discovery of petroleum and other sources of modern energy.

So how are we going to resolve water crisis? Have we implement a proper water management system? What steps need to be taken? For the time being, do not waste water.
