I think the so called "science" behind the lead shot ban dealing with waterfowl is about as bogus as bad science gets. Terrible doomsday type stuff. Banning lead-shot has done nothing to bring back waterfowl populations in North America. The banning of Market Hunting helped, restrictive seasons have helped, but habitat management and habitat conditions are the number one reason for the rebound of waterfowl numbers. There are huge populations of waterfowl in other countries that allow shooting of waterfowl with lead...the difference is their habitat conditions are way better than ours. There are studies out now that challenge these findings when it somes to waterfowl and lead. I never understood why its illegal to field hunt ducks and geese and shoot them with lead when you can hunt the same field for upland game and shoot all the lead you want. Doesnt make much sense.
I was thinking....on game refuges, Federal WPA and WMA's, where the signs say "NON-TOX ONLY" why doesn't that include rifle bullets or shotgun slugs? UH-OH, opening a whole other can of worms there....
