humans have been hunting since the dawn of man out of necessity. when humans were first around there were obviously no food stores for them to go out and buy some food. they had to hunt for it, and despite what you may think, they used the entire animal. everything, so nothing went to waste.

depending on which animals your hunting, some do have a chance. on the other hand, when your hunting deer, and your just sitting there with "bait" with a scoped gun aiming at their head, they don't really have a chance. you could say: "oh! they always could run away or not be so dumb." thats like blaming a fish being caught on its stupidity to bite a hook. bait is camolauged to looked like the real deal and the animal's instincts tell them it alright. so its not really fair.

true the conditions of most of meat processing plants for animals are cruel. horribly cruel, but at least the animals are being used for food and, hopefully, are going to waste. i don't know if you hunt for food or just for the sake of killing animals, but i think the later one is wrong. pointless killing for your own amusement.

also, just because you've been doing something your entire life doesn't make it right or justified. just because people have been doing something for years, again, doesn't make it right or justified.
