What I don't quite get is that if we feel like we could figure out how to live on Mars, couldn't we relatively easily figure out how to live on a hot Earth?

- chris012543 10y agoThe idea is to be a multiplanetary species. Not leave Earth for Mars. Plus, it's just really fucking awesome. That alone is enough reason for it to be pursued imo. Exploring and doing cool new things is part of what makes life worth living.
- s3arch 10y agoWe have made our earth worse for habitat, in the name of doing "cool things" and "make life worth living". But still we can live here and find happiness, unlike Mars. Living in Mars and building cities there is wonderful. The project might even succeed completely. But people will find more "emptiness" in space than on earth.
- Pfhreak 10y ago> But still we can live here and find happiness, unlike Mars. This is a wholly unfounded statement.
- reacharavindh 10y agoMars will be our Earth's active backup, in case shit goes really bad here(or, quite possibly we make it really bad here).
- dv_dt 10y agoThat's a different and more uncertain reliability model for continued existence of the human species - at least for the probabilities I'd personally assign for the events required for getting to mars vs a serious effort at fighting climate change. (Especially given how weakly fighting climate change is supported among the two mainstream presidential candidates.)
- Pfhreak 10y agoI'm sure learning to sustainably live on a hostile planet will result in technology we can also use at home. And vice versa -- pushing for sustainability at home will lead to technologies we can use elsewhere.
- _rpd 10y agoHaving multiple independent biospheres reduces a lot of extinction level risks, not just catastrophic climate change risk.
