Did you stop and think about Fearless Felix's jump? From 24 miles high in an unlivable environment. Alien and cold. But as the crow flies about the same distance in a drive from Albuquerque to Los Lunas. Not far at all. Felix was not at a life sustaining altitude until his drop from near space was 88% complete.
And yet all of our lives depend on a thin veil of atmosphere that can only sustain life up to about 3 and a half miles. Yet we just keep pumping more crap into it. And the world leaders can not even bring themselves to deal with it because it might cut into profits for the fossil fuel crowd.
