movie about water

I watched this movie over the weekend and I thought it was pretty interesting, everyone should check it out. It is a documentary that talks about how basically the world is running out of water. Water is becoming more of a valuable commodity rather than an abundant resource, and the world is now having to adapt to that. The movie is called "Blue Gold - World Water Wars". You can find it on Netflix, but I found it on youtube also, here is the link: http://www.youtube.com/watch?v=RjOn2THsQZg
