There is certainly an argument to be made for expanding. Humanity's chances of continuing to exist for x number of years improve drastically the moment there is a stable, self-sufficient group of humans on a completely different planet. It would mean we can no longer be wiped out by any single planetary catastrophe.
I think Mars is a dead end, though. Someone posted on here a while back about the concept of Venus colonies, up in the upper atmosphere. Those sound awesome, and they lack a few of the problems we'd face trying to colonize Mars.

Yeah, they actually have them in Wolfenstein reboot.
I think the idea is that they're built in a reasonably survivable area of the atmosphere. The ground is bad, but a few miles up is manageable.
I'd have to look it up again though. Basically read about it in passing a few years ago.
Venus is also more Earth-like as well in regards to size and mass. I suppose the benefit of Mars is that you're closer to the asteroid belt.
Yeah I remember it pretty well. I didn't know that about wolfenstein though, that's cool.
There's a NASA report about it (scroll to the bottom and hit the little pdf link)
Kurzgesagt has a nice video recently on terraforming Venus. What they fail to mention is that it would never happen under capitalism.
