The left uses environmental issues as a weapon for their cause. When it doesn't fit their cause it doesn't matter to them. As a sportsman (true environmentalist) I see wildlife as important all the time. As it relates to the original post of this thread, birds dying unnecessarily is a bad thing everywhere that it happens. I agree that it is "more bad" as it relates to the amount of birds that die due to green energy, by sheer volume. That doesn't mean that I shouldn't care about other things that effect birds, ie lead. I don't think it is a good idea to dump toxic waste into a river. That doesn't mean I am against mining.
Unfortunately there has been some sportsmen that have the attitude that they don't care about consequences of things they do because it is not as bad as the things others do. This attitude is is what makes us look bad and the left will use it to convince the people in the middle to join them against sportsmen.
There should never be a ban on lead ammunition. I have never changed my mind on that.
