Running Out of Water May 16, 2011

We've grown accustomed to using water with abandon, yet only 3 percent of all our water is drinkable. By this decade's end, when the world population is predicted to reach 8 billion, we will face severe shortages. Harvard professor Peter Rogers and former general manager of the San Francisco Utilities Commission Susan Leal will present a sobering perspective on the water crisis--why it's happening, where it's likely to strike, and what puts the worst strain on our supply. They will then discuss new technologies that can help revolutionize our consumption of water with examples from different areas of the world.
