"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. 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 journalist Anna Lenzer calls "the coming shock."

Susan and Anna join us in studio to discuss water: why we're limited, 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.
