Creating new means to move water from one basin to another can negatively impact both ecology and economy. Rather than risk it, experts suggest big picture conservation efforts—in communities, agriculture, and public policy—are essential, even in water-rich regions like the Great Lakes. Jared Teutsch of the Great Lakes Conservation Alliance and Kate Sackman of EcoMyths will join us to discuss the complexity of water supply systems. (Photo: AP/Marcio Jose Sanchez)
