What would happen to earth if humans vanished?

The point is that you don't have to hunt to maintain your sustenance though. I can imagine how hunting made you see your place within nature. I myself am a vegetarian so far in that I would only eat meat if I killed the animal I was consuming.

Even with convenience people can suffer. The more luxuries one has, the less meaning their life might have. To hunt to survive gives meaning to the struggle one endures. People actually like working though they might constantly complain about it. They need to keep occupied. Goes along with the whole money doesn't bring happiness scenario. One needs more than instant gratification to enjoy their life. Could that be why you felt better for have hunted?

Would a caged animal who receives regular meals have a more fulfilling life than one in the wild who has to work for their food? You can't compare many animals to humans in the same way. Many don't have as deep emotions as humans, or any at all for that matter. And as mentioned even fewer engage in sex purely for pleasure. (I think bonobos do as well.)

Even before humans became "civilized" and were as natural as one could be, they still hunted animals to extinction. Mammoths anyone? The point is that in this day in age humans can fix the mistakes they've made during their existence and try to live on this planet with nature instead of further destroying it. The Earth is but one rock with some living things on it which will eventually disappear all together...but it would be nice if the beings on it, humans and others, could maintain it in a manner until that day comes.
