One of the big reasons I support off world colonization is because that's probably the only way people will believe that the atmosphere is a thing. Similar to how people really didn't believe there was an "environment"[1] until "Earthrise" in 1968.

If they see "atmosphere" killing other people, all the time, on TV, because someone goofed the gas balance in the Muskdome, then they'll maybe crank up their critical thinking skills.
