This has to do with Asian carp, which are very close to getting into Lake Michigan. If that happens, it could effectively destroy the fishing industry in the Great Lakes. Last month, Michigan Attorney General Mike Cox sued, asking the court to close the locks connecting the already contaminated Chicago River with the lakes.
That lawsuit has been joined by Cox’s counterparts in Minnesota, New York, Ohio and Wisconsin. But it is being opposed by Illinois, and by the Obama Administration. The President is a political native of Illinois, and shipping industry interests in Chicago say closing the locks could cost the local economy $30 million in revenue, and inconvenience the entire region.
That, however, seems a small price to pay, given that many biologists think an Asian carp infestation could wipe out much of the Great Lakes‘ $7 billion dollar commercial and sport fishing industry, and do other ecological damage as well.
It is hard to exaggerate how great a threat Asian carp represent. There are two species, the Bighead carp, which can easily get up to a hundred pounds, and the Silver carp, which top out at half that size, but have another deadly feature.
They jump. Boaters and water skiers on the Mississippi have had jaws broken, equipment damaged, and faces lacerated by these appalling fish. But the bigger problem is what both kinds of carp do to the food supply. They suck it all up, consuming as much as a fifth of their body weight in plankton every day, starving out the other fish.
This all started years ago, when some fish farmers in Arkansas imported Asian carp and were raising them in outdoor fish farms. Then along came a flood, and they got into the Mississippi River. They’ve been working their way north ever since.
Six weeks ago, I reported here that an electric barrier on the Chicago Sanitary and Ship Canal that was supposed to stop the car had failed, more than likely because it was never turned on full-strength. This fall, an Army Corps of Engineers study found Asian carp DNA in the water within eight miles of Lake Michigan.
Closing the locks, at least for a time, seems to be the last realistic hope of stopping them. It is anyone’s guess how the high court will rule. It seems to be the first U.S. Supreme Court case in history where one state has sued another over invasive species.
More importantly, as Attorney General Cox says on his website, “the present situation presents a unique opportunity in the long and unfortunate history of invasive species entering the Great Lakes to prevent an invasion before it starts.”
Let’s hope that happens. There’s no guarantee the carp aren’t already in Lake Michigan, or that closing the locks will halt them forever. And, we should remember this too:
We could have done more to stop them a long time ago. Yesterday, Cameron Davis, a senior advisor to the U.S. Environmental Protection Agency, told a group of Michigan legislators that everyone had seen the Asian carp threat coming for many years.
Yet nobody did much about it.
Americans have a habit of waiting till one minute before midnight before addressing serious problems. One of these days, that’s going to be just a little too late.
