Comment: Isn't this a bit like closing the barn door after the livestock have made good their escape? I strongly doubt that a ban at this point would make a lot of difference in the long run with the damage having been done, and the enormous economic impact is not to be taken lightly. While it's blindly obvious that something needs to be done, an outright ban is a bit much.

MILWAUKEE -- A conservation group has proposed banning ocean freighters from the Great Lakes in an effort to halt the onslaught of invasive species.
Great Lakes United says shutting the St. Lawrence Seaway to seafaring ships is akin to closing a small factory that pollutes a town with its oversized smokestack. The freighters, it says, are bringing in invasive species that ravage native fisheries, ruin beaches and cost water-dependent industries billions of dollars.
At least 183 foreign organisms now thrive in the Great Lakes, and a new one is discovered about every six months. Research has shown that most arrive on overseas vessels that take in water in foreign ports.
