The State of the Great Lakes

The Great Lakes have suffered from a host of threats. Mercury, microplastics, nano plastics, sea lampreys, Asian carp, zebra mussels, and quagga mussels. How did those contaminants get there, and what are the challenges to getting rid of them? How much progress has been made since the environmental movement ramped up fifty years ago? And what’s causing the radically variable water levels in the lakes? Jim Hurley, the director of the UW Aquatic Sciences Center will give us some ideas about pinpointing the threats to the lakes and the status of efforts to restore or maintain their water quality.
