"We’re on a collision course with our finite supply of water," says Susan Leal, co-author of the new book Running Out of Water: The Looming Crisis and Solutions to Conserve Our Most Precious Resource. It’s not just that the supply is limited, she notes, it’s our growing population, increased personal use and climate change that are all playing into what Nation Institute Investigate Fund journalist Anna Lenzer calls "the coming shock."

Leal and Lenzer join us in studio to discuss water: why we have a limited supply, why privatization and drinking bottled water isn’t the solution and why the problem has a better chance of being solved when people work together rather than have decisions imposed by private corporations.
