Not sure where you get the idea that humans are the only ones who use weapons (or tools, in general). Ravens and otters use rocks to crack open shells of mollusks, and gorillas have even been observed throwing dirt (as in, to blind) and rocks (not small ones, mind you) at other animals, competing males, and even humans (which can be deadly). Chimpanzees have also been known to make spears and even hoard arsenals of weapons, and also use these spears to hunt.
So you say I shouldn't refer to animals I've killed as "harvested", but then say it should only be done for food. It isn't a term of disrespect, but an acknowledgement that these animals ARE killed for food. I cannot think of a hunter I've ever known who didn't eat what they killed. Hunters utilize more of that meat than anything you get from the butcher shop, which throws away "scraps" that most hunters would gladly use.
Something to think about, as well, is that most (deer) hunters only take one animal a year, and that animal's meat sustains them and their family for months. Think about how many chicken nuggets, cheeseburgers, and other meat products you've eaten in your life. How many animals died for those meals? Was it a fair way for them to die? Did they die in the wild, or in a meat factory where they were fed ground up meat (of the same animal) in their slop they were forced to eat?
Hmm, and what of spiders and their webs? What of snakes and their paralizing venom? What of the eagle that swoops down and snatches the unsuspecting fish? Successful hunters don't expend more energy than they consume. If they did, they wouldn't last long as a species. There's a reason that humans stopped running after animals in favor of growing their crops and using bows and their wits.
I agree that it isn't right to kill for fur or trophy exclusively, as it seems disrespectful to me, but not all people do this. In fact, the fur trade is in decline as synthetic fur grows in popularity and reduces in price.
I agree that the natural way coyotes and wolves select their prey is beneficial to the species of their prey as a whole, but unfortunately that isn't the way things work anymore with the way humans have screwed up the balance of nature. If, for example, wolves or coyotes go unchecked and overkill the deer population, a disease can pass through that community of deer and wipe out the rest of them. Similar situations have happened in the past, and if unchecked, can absolutely lead to mass extinctions (there's already a lot of worry in regards to antelope herds).
Unfortunately, as people grow on population, their impact on the balance of nature will only strain it more.
Edit: just so folks know, I'm talking about USA when I describe people's impact on nature.
