I disagree. We have evolved to this point because we are super predators and because we are inherently greedy and self-serving. I don't see that changing any time soon, although I do agree that is a laudable goal. Unfortunately, now we have the technology to wipe out everyone and everything very easily. I believe the threat of a nuclear war is not a matter of if, but when. It is in our best interests as a race to expand beyond this planet so when this does inevitably happen, we can learn from that mistake and try something different on our other worlds.
