I see the logic but don't agree.

Even if Mars or another planet were to survive the destruction of Earth, a stand-alone colony or space station would be doomed. At best I think we're at least 100 years off for any long-term self-sustained space colony... and it's quite possible we'll be sidetracked significantly if the climate causes widespread migration and famine as expected.

If we can't solve exponentially simpler earth-based problems, then I think we have no business in expanding, and would be unlikely to succeed regardless.

I support space exploration and development, but putting more resources outward when we have so many inward problems feels like a fool's errand.

We can work on both, but one's a much more imminent danger.

Your mistake is to prioritize climate change over space exploration and not some other industry. Spending on space exploration is tiny compared to, for example, consumer electronics or entertainment. Imagine how much we can save if phone lifecycle is five years instead of two; or if video games playing time is reduced by half, etc. So many candidates, yet you choose to target space exploration, an industry that has historically been responsible for so many science and technology innovations.

I'm not targeting the industry, I'm assuming that nothing will change when it comes to the space industry's current funding. No one's going to gut consumer electronics for space, it will never happen.

Given the current low-level of funding we should be focusing on defense (climate reliance, threat detection) rather than colonization. I'd be over the moon if space industries were better funded to do both... but more often than not total funding as a percentage of GDP has been decreasing, not increasing.

We think alike - but IMHO that's going to happen only if we begin now. That's why we shouldn't hold off.

It's not like there's a single "we" that can keep attention at one thing at a time only. There are a lot of great engineers excited about space stuff, who don't care about ecology/whatever else at all. It makes sense to use their skills and enthusiasm while other engineers excited about that work on solving our Earth-bound problems.

Another point is - whatever helps us survive on Mars and the Moon will help us greatly to reduce harm done to Earth.

For sure, but there are also dangers other than climate change - war, asteroid impact, pandemics, rogue AI takeover... It's not that either Earth gets destroyed and the Martian colony will die anyways or nothing has happened and we don't need the backup.

Perhaps there will be another pandemic and the people on Earth will die off but the Martians survive. Perhaps asteroid impact will make Earth uninhabitable for 10-50 years but no more. Etc
