Why would you think that we send 7bn people into space? There should not have been 7bn people to start with. It just happened because somehow species tend to multiply until their environment can't sustain further growth. In space, it will be MUCH harder to sustain a population, as a result, the population there will be much smaller (think of maybe 100.000), at least in the early stages.

I agree that we should be able to save the earth. I think both are possible and also intertwined, because whatever our solution, it will likely require advanced capabilities to deploy technology into earth's orbit, be it large scale solar shielding, some atmosphere transformers, or whatever.

Still, repairing earth and creating space ships are two different things. We did not design earth, and the size of it makes it hard to control. It will be MUCH easier to sustain life in an underground lab (or space ship) than it is to repair earth. At least conceptually. But of course you have a point that we should not abandon most of the population for two reasons:

1. It's a bit cruel and probably only the worst of mankind will survive again, as it always did.

2. Project "Space" might turn out to be one hell of a disaster, since it's hard to predict how humans will fare in space. So we should have a backup plan.

If we can't avoid overpopulating a planet, how and why should we think will we avoid overpopulating Mars or Mini Ringworld?

Well if plan B in space is for only some, it's not saving humanity but is a "fuck you" to most of them. I think some pretty core human problems will show pretty damn quickly after that:

Once the remaining 6.9bn realise they're not invited to the party, that there is a definite plan for all the wealthy and politician types to piss off to Mars or some space station, the rest might very reasonably decide that's a tad unfair. Especially if their own future is some apocalyptic die off, perversely made worse by all those emissions from the thousands of rocket launches. They might sensibly think that instead of quietly waiting for the 4 horsemen to show up with their exit, better to go out by trashing all the supply rockets and bases of project space, and reach for petrol, pitchfork or assault rifle. Maybe one more emission laden launch to blow those entitled assholes out of orbit...

We haven't yet shown viability in any of the sealed biome experiments. Not once. The old Russian experiments back during their lunar programme got closest.

Hence me thinking much cheaper and simpler just to address the damn problem properly. :)
