Jim Pinkerton agrees with Stephen Hawking, that we need to get some of our earthly eggs into other baskets.

A commonly held public fallacy that seems to be coming out on this topic is the sentiment that we need to sort ourselves out here on Earth before seeding space with our destructive tendencies. However the biological determinist argument goes something like; nature created us in its own brutal image and only by getting out of this environment and into space can we hope to evolve out of our murderous ways.

Another common fallacy that kind of follows from this is the let the human race die out so that something better can come along. Of course the biological determinism argument would infer that the second coming of intelligence on Earth will be unlikely to be any better than humanity and perhaps even worse due to the more highly evolved and intense competition it will likely have to overcome to get there.

Has there been any public debunking of such fallacies? It seems a common view incurring little direct response.
