We need a fundamental shift to meeting basic human needs and improving efficiency rather than continuing to find new sources....the problem is......

Some skeptics have noted that global warming could have a fringe benefit -- more carbon dioxide seems to hasten plant growth, but that can't happen without water, or if the land gets too saline.
Overall, the problem is an unending demand, caused by soaring population and industrialization, splashing up against a finite supply. The water crisis is "definitely getting worse," says Rajawat. "The basic issue is the fact that water is renewable but finite, any place where the population grows, you'll have a diminished supply per person."
Rather than continually looking for another river to dam, Rajawat suggests working more intelligently with the existing supply. "We need a fundamental shift to meeting basic human needs and improving efficiency rather than continuing to find new sources. That's a no-win proposition. Every additional unit we take out of the natural environment causes environmental degradation. We need to do more with less through a focus on policy and institutions."
