I highly recommend the film Blue Gold: World Water Wars. Take a look at the trailer.
"Corporate giants force developing countries to privatize their water supply for profit. Wall Street investors target desalination and mass bulk water export schemes. Corrupt governments use water for economic and political gain. Military control of water emerges and a new geo-political map and power structure forms, setting the stage for world water wars."
"We follow numerous worldwide examples of people fighting for their basic right to water, from court cases to violent revolutions to U.N. conventions to revised constitutions to local protests at grade schools. As Maude Barlow proclaims, “This is our revolution, this is our war”. A line is crossed as water becomes a commodity. Will we survive?"
