Will man inhabit other planets?

If I may add, it's not that we need another space in case that the living space of the earth is too small, it's about self destruction or natural cataclysm. In theses cases, there is unlikely that human will survive, even if there are some in the oceans. The best way to save humans from extinction is to colonize another planet.

Are we really doomed as a species if mankind doesn't get his butt into space? Stephen Hawking has stated that colonisation of space would be the best way to ensure the survival of humans as a species. There's a site online about the Colonisation of Venus http://en.wikipedia.org/wiki/Colonization_of_Venus Though theoretically possible, it'd be very very expensive and time consuming, which suggest that it will not be done for many thousands of years, if ever. Certainly not in our lifetime. I don't think any one organisation could ever afford it. Earth is what, 3/5th ocean? I dare say it would be far easier and cheaper and desirable to settle either the surface of that water or even in the depths of it if somehow if we found there is not place enough for all of us on Earth I do believe that we'd better do something about the population we have now as no one wants to face up to the reality of what will happen if we don't.

No, sadly as much as I would like it to be the case, I don't think man will inhabit other planets in our life time. I am afraid we will all perish here. I would be one of the first to volunteer if they would accept me, but it doesn't look good. I hope it will happen for my children's generation.

Man will eventually die off if we don't move to another planet. Whether it be nuclear war, disease, asteroids, etc., the Earth will eventually become inhabitable. How long we have before life can't be maintained on Earth is the big question. A nuclear war could break out tomorrow, or it could be thousands of years before anything major happens.
