> There are a huge number of humans on earth who spend their lives in urban centers and also never have those experiences.
Those people can and do at least go to parks.
A better analogy is that it would be like living in an underground bunker on Death Valley, with periodic excursions out to the desert, while wearing a spacesuit.
There are a few theories for getting magnetic poles going on Mars. With that, and some terraforming, and a whole lot of time, they could eventually have a breathable atmosphere.
Of course this will take many hundreds of years and need a bunch of new tech.
Anyway, for now, we can breathe the atmosphere when we go outside. That's not what it's like on Mars. I don't think I'd enjoy that.
