If we were to invest in building a underwater 'Sealab' on the bottom of some ocean floor, say at least 100m water deep, what kind of cataclysmic event could destroy it.
A few dozen of the underwater sea-colonies seams the most practical safety net for humanity that we can do today.
I completely for exploring and colonizing space, but we still haven't mapped our own oceans fully. And sadly, I don't think my generation, or even the next few will be any closer to being able to get ourselves off this rock.
If you are looking to build 'Arks' for humanity, i'd put my money on the ocean floor.

Maybe a sinking ship landing on the dome might be a problem. Or depth charges dropped during war. It would be considerably more difficult to destroy a colony on Mars through physical intervention, intentional or not.
... hacking in and opening all airlocks and evicting all oxygen, like fire suppression systems, on the other hand...
