Have you ever considered how much it costs to keep unlimited clean water flowing into your faucets at home? Or how much water goes into growing all the food that you eat? Can you imagine our supply of water running out?

These are topics we explored during our interview with Robert Glennon, Professor of Law and Public Policy at the University of Arizona and author of "Unquenchable: America's Water Crisis and What To Do About It". He is on a mission to hold government and individuals responsible for true stewardship of our greatest resource: water.
