If we can send people for generations in space, we believe we can live sustainably. If we believe we can live sustainably, we should be able to do it here. We aren't doing it here, suggesting we're dreaming if we think we can do it elsewhere. Even if we aren't, the best we to show we can do it is to live sustainably. We're not. We could at least show we could live sustainably underwater or in Antarctica, but we can't, even with a world of resources and help, and they're easier than space. It seems the best way to make other planets possible is to live here sustainably. I suggest we devote the resources we're using on those problems (space travel) on this problem (sustainability on Earth), since it will also help those problems, if they're possible.
