I bet Space Travel is going to play a major role in our later survival, the Earth will once become too small for it's population, a population which could already have consumed/destroyed much of Earth's resources.
Ha ha, doubt it. Even if it was we'd only move to another planet and destroy that.
Now Space Travel is like taking a walk around the block, you know where you're going, you've been there before and you'll be back in a quarter of an hour. What I mean is that the needs of life should be put into a spaceship, a small world, for it's passengers to survive a long way, so that even on board, astronauts are trained, childs are born, children are taught at schools, universities, high schools, markets, food should be produced, fuel shouldbe created, Oxigen should be created and the carbon dioxide should be removed(maybe by plants)and so many more things. Also don't forget about the animals, you need males and females of nearly every sort, and which animals are you going to take with you, and which you won't ? It could create a major problem in the food chain, because you can't put all animals in one box on that ship.
I don't have any faith in space travel, the things you see in star trek etc aren't possible, how can you "fly" through a vaccum?
I think if anything happens we should stay on earth and accept the consequences of our ignorance, arrogance and stupidity of ignoring how fools like George W only made us step back as a race, not forward.
