Fact - Lead is poisonous to humans, animals, birds and fish.
Whether or not it's the sole culprit in cases of Condors that die of lead poisoning or not, there is little doubt that it plays a role and likely plays a role in other species as well. While California's overnight ban of all lead is a bit draconian, I'm confused as to why so many hunters, most self professed wildlife lovers, have such a problem with moving on to another substance that is less harmful to wildlife. When I'm out hunting, I very much enjoy all the wildlife I see and if my ammunition is hurting the very thing I enjoy, then I have no problem with using another type of bullet, even if it might cost a little more at first. If done gradually over time, once it becomes standard the price will come back down.
We moved past leaded gas, why can't we evolve past leaded ammunition?
