There's an editorial in last Tuesday's Milwaukee Journal Sentinel calling for the closure of the St. Lawrence Seaway in order to prevent ocean-bound ships from transporting new invasive species into the Great Lakes. The reasoning behind the idea is that freighters should be banned from the Seaway until the shipping industry can prove that appropriate measures are being taken to avoid introducing ballast invaders to the region. The Journal Sentinel also published an in-depth two part article on the subject last week.
Got an opinion on this? The MJS is looking for letters to the editor on the subject - details are at the end of the editorial.
