This is just a left wing political ploy based on voodoo science like most of their tactics. The socialists* managed to get a trap & skeet operation shut down that overlooked Lake Michigan in Chicago when I was unfortunate enough to have to live there. They claimed the shot was poisoning the fish and waterfowl. After, unfortunately , the range shut down a study was done that determinted the lead had sunk 10 feet into the mud at the bottom of the lake. Environmental impact? NONE.
*What these left wing scum really didn't like was the fact that thousands of people driving on Lake Shore Drive were seeing dozens of people at a time peacefully enjoying the use of firearms. Fortunately shorty after that Jim Thompson, who was Governor at the time, grandfathered all other shooting facilities in the State.
Get out and vote this November!!
