Our only chance of long term survival, is not to remain inward looking on planet Earth, but to spread out into space.

I think the human race doesn't have a future if we don't go into space. We need to expand our horizons beyond planet Earth if we are to have a long-term future.

To give us room to explore the varieties of mind and body into which our genome can evolve, one planet is not enough.
