The Great Lakes hold 20 percent of the world’s fresh surface water. If climate change leads to increasingly severe droughts in places like California or Arizona, it’s easy to think those states might start eyeing the Great Lakes as a solution to their water woes.

He joins us to talk about the laws that protect the lakes and the court cases that are testing the strength of those protections. Photo: Flickr/Ken Lund
