Holy shit.
I've never been alive in a time when every human has been on Earth. That's crazy to think about...

Space is a priority so we can ignore climate change. Rockets put our many many plane flights worth of pollution, elon musk has done over 30,000 of them (mostly for StarLink). Quite a few ended up just dumping raw pollution and parts into the ocean.
No price is paid but by the environment.
Rockets are launched so infrequently that their effect is negligible compared to other sources of pollution. They're definitely still a problem (debris falling on populated areas is a concern), but the aviation industry burns a rocket launch worth of fuel a few times per minute.

Well, technically speaking, we all are in space.

Can be at rest in your own reference frame without falling to earth?
From your own reference frame, wouldn't earth be falling to you? Because then this'd apply to everyone, always.

Are you saying that people jumping ARE on earth? Because I disagree.
They're clearly not "jumping" they're pushing the earth away

By 2030, everyone will most likely be back on Earth again when the ISS gets decommissioned

I mean 30,000 feet is 9km. The Kármán line is 100km. The ISS is at an average altitude of 400km.
It's a bit like saying people in planes don't count as flying because then people on trampolines should count.
Also people who live in a basement, or cave, or underground complex of some kind, or who are currently caving, ... they also aren't 'on' Earth, they're 'in the Earth', ... and people currently in submersibles, under the water line, well they're not on the surface, they're in or under the ocean or w/e, by this grammatical level of pedantry.

This planet ain’t big enough for the two of us.

China will still have an operational station. Probably.

If you like pedantry, people have definitely flown in vehicles and even jumped.

China has their own ISS.

Are you saying that people jumping ARE on earth? Because I disagree.
Are there enough trampolines on earth that we could reasonably expect that at any time there is at least one person in the upper part of their jump on a trampoline?

Hmm, I think this logic kinda fails because if astronauts are "not on earth", then neither are air travelers.
Astronauts orbiting earth are just couple kilometers higher altitude
Spent a moment thinking about this and I think there's an implied definition for what "on earth" means that we intuitively accept but don't ever really need to state.
If your projected free-fall trajectory both forward and backward in time intersects with the surface of the earth then you are "on earth".
Standing on the ground? Intersects twice.
Thrown rock? Intersects twice.
Person in an airplane? Intersects twice.
ISS? No intersection.
Incoming impact meteor? One intersection. -

2012 is still pending just waiting for us all to be gathered up so as to not have any loose ends.
