After more thought, I realize I was mistaken in arguing that we should simply bar ocean-going ships from the Great Lakes to keep exotic species out. What we should do is bar saltwater ships and block the Chicago Sanitary and Ship Canal, plugging the lakes at both ends.
Otherwise, we risk losing a $5 billion annual sport and commercial fishery and who-knows-what in tourism and biological diversity so that a handful of industries can save a few bucks.
