Just wanted to chime in and see what people's opinions are on this subject.
A good primer would be to watch this video of Prof. Machio Kaku:

My question is, will we ever get off this planet before it dies out? I mean, the Earth IS a dying planet. Will we ever get past type 1? Type 2?
I always imagine that as humans we can if we put our minds to it, but look at the state of affairs around us.....look at NASA's budget for crying out loud. Things like this make me feel that our future is not only uncertain but that we're basically screwed.
I have faith in human ingenuity but as a pessimist I know for a fact we're never getting off this planet, at least if things continue the way they are.
Oh, and we're considered a type 0.7 civilization on the Kardashev scale:

I have been so fascinated w/ cosmology lately that I think I will be going back to school to earn my degree in Space Sciences, just gotta find a good school (suggestions welcome).
