>it'll become crowded really fast That means we'll have a lot of brainpower to figure out the space exploration thing. If anything, it's more ecological than taking multiple generations to do it, since you wouldn't waste time having to raise researchers over and over again because the previous generation has died. Also people would have more reason to care about the environment since it's their own life at stake.
