There are states where game wardens and other wildlife management types have to cull deer herds, etc by the THOUSANDS to avoid overpopulation. This is to prevent many things, not least of which would be people dying in car accidents hitting or attempting to avoid deer. Sometimes they collect the deer and distribute them to homeless shelters, etc... usually not. That's a tragic waste, IMHO.
At it's most practical... hunters fill a void left in the natural world when humans removed most of the predators (wolves, etc). Without hunting, you'd have obscenely large mass killings by wildlife officials to control explosive animal populations. Feral hogs are a BIG problem, and it unfortunately has gotten to a point where people actually have to go out and kill them by the hundreds... which I also find somewhat tragic. Wasn't there a drone story about people hunting hogs just a bit ago? Hogs just aren't thought of as good eating, so not enough hunters target them.
So... animals are going to die regardless. Wildlife officials generally try to balance permitting to the animal populations... so hunters do what the wildlife people otherwise would have to. Fees from hunting is a major component of funding for the parks department, too. So... lose hunting and you'd probably lose a lot more parks than we already have. (Then new farmers or developers would then eradicate or displace the animals)
Sure, there are drunken idiots that shoot at shadows and highway signs... but there's MANY more very responsible hunters out there who respect wildlife and the wild places they live in. The vast majority of hunters I know try to minimize suffering and work to maintain healthy animal populations.
Hunting makes you very aware of the outdoors and a much better steward of it than the unthinkingly blurting out "hurting animals is wrong", never contributing anything towards wildlife management, and then going to McDs to chow down on food from animals that are confined to areas barely large enough for them to stand in for a good part of their lives. That's better?
It's very distinctly obvious to anyone who spends time in both the country and the city that the vast majority of the people screaming about overly broad animals rights don't actually spend any time with wild animals at all. Their main conceptual interactions with wild animals are from their own pets or Disney cartoons, which are all heavily anthropomorphising. So, it's not all that surprising that they end up thinking that way. It's all a lie, though. Man is a predator, and it's entirely natural to be what you are. You can try to "rise above" our animal roots... that would make for an interesting conversation... but really what I see is much more "out of sight out of mind" BS. The casual person saying "hunting is wrong" consumes animal products that involve much more animal suffering than meat by way of hunting does.
I certainly plan to introduce my son to hunting when he's old enough... I just hope by the time that happens he hasn't been brainwashed into thinking it's wrong. I'm hard at work brainwashing him to think otherwise ;)
