And if you read this column (disclosure: I submitted it, not the author or any other connection) it's very clear that we can't maintain one planet, yet: https://news.ycombinator.com/item?id=17642191

I think the Mars hype might be a symptom of some sort of societal anxiety and recognition that we are 50-100 years out or less from an extraordinary and preventable tragedy.

This cannot be understated. For the resources we would throw away trying to build a self-sustaining Mars colony, as a lifeline for a few thousand people, after a one-in-fifty-million-years extinction event, we could probably prevent a climate catastrophe on Earth.

Not a hypothetical one-in-a-million-years climate catastrophe - but rather, one that we are right in the middle of.
