The Great Lakes do need to be protected from this Huge invasive danger. There is one good point brought up here. Why were these fish allowed in this country in the first place????? Drastic measures may be what is needed to stop the carp, but they need to happen now. Even if there were 10 sure fire ways to stop the carp, the bureaucrats would argue for 10 years about which method was best. It's all about $$$$$. There has been a lot of harm done to the GLs over the years. The GLs are the source of drinking water for numerous municipalities. These same municipalities spill billions of gallons of semi treated sewage into the GLs every time there is a major rain storm. Sure they get a slap on the wrist when this happens. Separating the sanitary and storm sewers is the answer to this dilema, but $$$$$ keep it from happening. Some big improvements have been made in the GLs water quality and fishery in the last few decades. I hope we don't start going the other way.
