Sustaining 20k people in Antarctica isn’t a problem people can’t solve, it just isn’t at all useful. Sustaining a colony on mars would be useful to mitigate planetary scale natural disasters. The problem is humans as we exist bow are not likely to either spend the resources necessary or take the risks necessary to colonize mars for a long term and uncertain risk mitigation. We can’t even get a large % of humans to stop buying SUVs with vastly excess horsepower to avoid ruining our planet in a relatively short time frame. The societal/political problems seem larger to me than the engineering ones, which are just a matter of effort.
