From the Chicago Tribune:
Despite decades of efforts to restore and protect the Great Lakes, dozens of old power plants still are allowed to kill hundreds of millions of fish each year by sucking in massive amounts of water to cool their equipment.
Records obtained by the Tribune show that staggering numbers of fish die when pulled into the screens of water intake systems so powerful that most could fill an Olympic swimming pool in less than a minute. Billions more eggs, larvae and juvenile fish that are small enough to pass through the screens are cooked to death by intense heat and high pressure inside the coal, gas and nuclear plants. Read more.
