Mood debuff from the game Rimworld where if you spend too long without going outside, you get a severe penalty.

In other words, being underground for long (or indefinite) periods would probably have a profoundly negative effect on people's moods.

Thank you

There's also water and air, just not anywhere close to the amounts we want.

Honestly making all our corporate bullshit buildings on other barren planets would be way better than acting like a cancer on the ecosystem on earth. If we manage to become space fairing, I hope they can restore earth and reduce our spread on it. We don't need concrete jungles.

Nah, we just need to crash Mercury into the surface of Venus, get the rotation sorted out and a moon going. After that, buildings.

Yep, yet it's my understanding that it'd be easier to colonize Venus than Mars. Venus is closer, Venus' gravity is similar to Earth's, the air is extremely dense which means balloons would be very effective, iirc Venus has more opportunities for inter-planetary transit, high-altitude temperatures (where the balloons would float) are more similar to Earth's, etc.

Yeah what would be the benefit to colonies Venus vs just living in space? Gravity?

That's why balloons! You can have sick blimps on Venus and IIRC you can capture atmospheric gasses to burn as fuel for them and to create water too.

Yeah but people and corporations would have to change and that's too difficult instead we should do something easy like colonize another planet. /s
