We most certainly need to be looking toward getting Humans situated elsewhere. All our eggs are in one basket ATM. If a big rock where to get knocked out of it's orbit today, putting it on a collision course with Earth in say 30yrs time, would we be in a position to save ourselves ? Maybe, but maybe not. We know for a fact our time on this Planet (and in this Solar System for that matter) is limited by the lifespan of our own Sun. So eventually we need to be able to go to other Stars, etc, if we wish to continue. I believe the experience gained from going to live on the Moon and Mars is pretty much the only thing that is going to allow us to come up with the necessary technologies to eventually venture out of our Solar System. So I say bring on the Moon and Mars. Besides I for one can't wait to find out if there is/was life in our Solar System and beyond. I'm firmly betting there is.
