If I could put a little less lead in the environment I would prefer to do so...
Where do you reckon that lead came from before it ended up in that copper jacket?
I see your point and personally I don't worry about the small amount of lead from the bullets I shoot. Lots of that is caught in the berms at the local range. And the amount that goes into the environment from hunting is miniscule.
But to answer your question, the lead originally came from a lead mine. Many of which were abandoned and were/are environmental disasters. Some ended up on the Superfund list, and many still aren't cleaned up. The ones that have been cleaned up have cost a lot of money.
Along with lead smelters and battery recyclers (also "where lead comes from"), lots of problems caused by lead contamination in the environment, and some of those ended up on the Superfund list too..
