just because animals that are bred have instincts, it doesn't mean that they have the ability to survive. Think of a stray cat, most straty cats end dying because of lack of food. Chickens will probably have the same problem. \
Its in our nature to eat other animals, and although we don't need to to survive, there are lots of other more harmful things that we dont need to survive that we still use like cars. Killing animals for eating in my opinion isn't wrong in itself, i just think that it's unfortunate the process that the animals we eat go through to get on the dinner table.
As it is, the world is our resource for humans to live off of just like any other animal. The problem is that we are living off of the world in a way that is going to prevent other species ability to live, which i think, along with most people is wrong. Unfortunately, i dont think that at this point, we can really prevent this disaster. The world is growing at an incredible rate, and the resources are constantly getting chewed up.
Eventually, evolution will take its course, we will probably all die out because of war or starvation, and either become extinct or move off to other planets. The world will slowly decompose and more forms of life will arise and any evidence of humans will disappear. That's my one condolence when i think about us destory this world.
