I don't think that because the rich b-stards think that. I think that because I believe our species - regardless of race - has outgrown its environment. If I got this idea from somewhere else, it wasn't from Musk or Bezos or others like them. It might even have come from watching Star Trek or reading sci-fi.

We're like a virus or a cancer that will ultimately end up killing the host. Earth's biosphere in this instance.

The correct course of action is to destroy the infection or cut it out.

And if you want what's being cut out to survive afterwards, yes, you have a lot of work ahead of you before you do so to ensure its continued existence once it's somewhere else.

We need to consider what it would take to get every single one of us off this planet and living somewhere else.
