> Houses, heating, cooling make us resilient to outside temperature and weather changes Heating and cooling necessarily heat the exterior of the heated or cooled environment more than they do heat or cool the interior. As the temperature warms, you need to cool your interior space even more, pumping yet more heat into the surrounds. For one, all that energy has to come from somewhere. For two, hopefully you don’t drive the system beyond a point where your heating and cooling can keep up. > There are people working on plans to colonise Mars - while that might not be viable in the short term - we are talking about making an environment without an atmosphere suitable for life - and there's no reason why this shouldn't be achievable. Reducing reliance on systems such as plants requiring bees for pollination should be trivial in comparison. There is a huge, vast, expansive, unimaginably large, ridiculously wide chasm between “working on plans to colonize Mars” and “actually colonizing Mars.” In the meantime, we’ve got ~10 billion people dependent on the existing ecosystem we’ve got here. Keeping that global ecosystem healthy enough to support those people without massive die-offs or total chaos, without the benefit of any globally organized effort to speak of, is deeply and profoundly not trivial, probably much less trivial than supporting a very small population on another planet. Plus, even if we do manage to colonize another world without first learning how to maintain the one we have, what exactly is the end game? Hop from planet to planet, destroying any life we find or create along the way?
