Water is a huge problem. Even in the U.S. the southwest is already fighting over diminishing supplies of water, and global warming is only going to make that problem worse.
The irony of the situation is that states like Arizona and Texas, who stand to lose the most from climate change and environmental damage, are politically the most intransigent about taking the measures to avoid it. When water supplies start drying up, people in those states are going to feel the pain far sooner than the dirty hippies in Washington and Massachusetts (though total pandemonium in the southwest isn't going to be good for anybody).
Interesting, we were going down a similar path in Victoria, Australia with falling water supplies. They build a very expensive desalination plant. Now it has turned around with 3 or 4 wet years so we are about to have this plant come online and not needed in the foreseeable future.
Google Arizona v. California. It's the reason states like Arizona oppose 'environmental' legislation. Because it always seems like what's good for the 'environment' is whatever allows CA to steal more water for itself.
