Humans are animals. The only difference is that we are intelligent (im not saying all other animals are stupid, some have desplayed incredible amounts of intelligence). We are structurally weak, soft skinned, and i bet we taste good also. We dont have claws, our teath are not incredibly sharp. The only form of natural defence we have is our brain, now we just need to get others to think
I would not press the button because there is no reason to. We are still evolving into a more perfect race. But we will not reach that stage untill we learn to conserve our resources.
