I agree with you that we need to change the way were living before we screw up Earth, but that's a process that can be run in parallel with space exploration. In theory many of the technologies used for colonizing other worlds could be useful for making our existence down here more sustainable, and vice versa. It's not like there is a finite amount of science points and we can allocate them all to one thing anyway.
