I think the difference is "perceived cost of the catastrophe". Many parties believe or choose to believe that all the damage done can be reversed, or it can't be that bad (which is very wrong, BTW) or, I'll die anyway, who cares.

For space, this perceived cost might be higher so, the limited number of parties might be more cautious.

Indeed I'm aware of The Tragedy of Commons, but from my view, space is a bit more nuanced.

Wish we were much more diligent about our planet though. We, humans, pillage it like all resources are infinite. Sad.
