The Silver Menace, or Battle for the Great Lakes

Imported from Taiwan and brought to Arkansas as weed control agents three decades ago, Asian carp have become the poster children of potential threats to the Great Lakes. As the fish inch closer to invading Lake Michigan, regional and national politicians debate the financial consequences of coping with the invasive species. With the fate of multi-billion dollar a year industries on the line, the Obama administration has offered some fiscal support to quell the storm.

Meanwhile Michigan's Lt. Gov. has taken his case to the Supreme Court twice, hoping for sweeping action. The conflict ignites deep-rooted water debates, including resource rights, diversion legitimacy, and long-term conservation planning. As action remains slow and debates continue, the invasive species become increasingly more threatening to the region.
