The Environment Report: Interview: Asian Carp
"The US Supreme Court has turned down a request from Michigan and
other Great Lakes states. They
wanted the locks in a canal to
be closed immediately. That man-made
canal artificially connects the
Mississippi River system and the
Great Lakes. For now at least,
those locks will stay open to cargo
traffic. This fight is all about
a fish, a type of Asian Carp, that
many people don't want to get into
the Great Lakes..."
