This isn't the first mass extinction the planet has seen.
- gnarbarian 5y agoYep. This is why I am dead set on one of those tickets to Mars.
- dathos 5y agoYou have seen what Mars looks like right? That planet had way more potential for you to perish than this one
- SilverRed 5y agoIts crazy how everyone sees mars as some kind of safety rope when climate change goes bad. Surviving on mars would be 100x harder than the worst case scenario for life on earth.
- mjevans 5y agoMost of what would make it more survivable is the small quantity of other humans and the need for "exotic on earth" life support infrastructure already required. Though to be viable as a backup for our species the colony would have to be able to survive, as well as be genetically viable, completely solo. Such preparation might include a "seed" vault for both plants and life, as well as a Horizon Zero Dawn style repository of all human knowledge. BTW that would also be a great international education standard for children even without it's use in the Doomsday setting.
- bildung 5y agoIsn't the small quantity of humans exactly what makes it less survivable? The smaller the group, the more severe a single fault in the system. This is the way habitats ecosystems work anyway. A trivial example might be aquariums: the bigger the easier to maintain a healty equilibrium.
- mjevans 5y agoIf you have 1000000 people, there's a very high risk at least one is crazy or illogical with respect to survival. If you have a couple hundred really well examined people who all really wanted to be somewhere the odds are much better, and all the more so, that problems can be contained when identified.
- lolc 5y agoRomantic prepper fantasies. With a couple hundred people, the bus factor of a tech society is wildly negative. Meaning, you'd need miracle spawns of workers already trained to keep up with just maintenance. On Mars the whole thing would just collapse and people suffocate once the parts shipments from Earth were disrupted for a substantial period.
- rrobukef 5y agoGiven that mental illness is prevalent and that we misdiagnose mental illness at a rate >1%. There is a already high risk in a couple hundred people. Furthermore, some 500 healthy adults do not form a stable society. Being in a high risk environment will flare tempers, 500 is on the low side of genetic diversity, there are no children, there will be pregnancies...
- sfink 5y agoSo some form of meritocracy. Are there any instances in the history of the human race where that idea has worked? My impression is that it always fails due to corruption or incorrect evaluation metrics or some other fundamental flaw in the starry-eyed idea of separating "good" from "bad". In theory, it's perfectly straightforward to write a flawless, unexploitable large program in C. In practice, we get hacked by plugging something into a Lightning port.
- res0nat0r 5y agoExactly. It's crazy that so many folks are buying into the dream of moving off world successfully before the planet is uninhabitable. I think this is just tied to billionaire hero worship. We should be shaming them for wasting money vs. spending those billions to force real change on Earth to fix the climate situation here which will come due long before any off world living will be anywhere close to reality.
- chriswarbo 5y ago> We should be shaming them for wasting money vs. spending those billions to force real change on Earth to fix the climate situation here which will come due long before any off world living will be anywhere close to reality. That's a false dichotomy, and just as much of a fantasy utopia as the 'solve our problems by moving to Mars' crowd: - Space exploration and technology is an investment, not a waste. - Space technology is not in competition with climate fixes, it helps. The most obvious example is Earth observation satellites, which are monitoring vegetation, cloud cover, ocean height, atmospheric composition, natural gas flares, forest fires, volcanic emissions, etc. right now. More long-term, reducing launch costs (like SpaceX is attempting with Starship) would increase the viability of solutions like space-based solar (24/7 sunlight, no atmosphere or cloud attenuation, no limit on surface area, no competition with agriculture/housing/etc., much less material/structure thanks to micro-gravity, etc.) - Meanwhile there are billions being wasted on vanity projects (superyachts, palaces, etc.), and on actively harmful activities (the US war budget comes to mind), which are far more suitable targets than space tech. - Online comment threads aren't going to change the spending habits of billionaires. Sure, if someone's making bullshit claims online (like 'moving to Mars will avoid climate change' or 'we should fix the climate before spending money on space') then calling them out can be good (hello!); combatting misinformation can sway the public discourse, even if just a little bit. On the other hand, armchair philosophising between like-minded individuals achieves absolutely nothing. Finally, it's probably worth saying w.r.t. 'long before any off world living will be anywhere close to reality': off world living will never become reality if we (as a species) don't bother trying. Self-sustaining colonies on Mars, the Moon, etc. will probably take centuries, but only if we keep taking baby steps in that direction today. Before Falcon 9, the industry was pretty content to milk a few cash-cow rockets for inflated government contracts. Now re-usability is becoming expected (e.g. ULA's hand-waving platitudes about one day catching Vulcan's engines). Starship is a huge gamble, but I'm happy someone is trying it. The Human Landing System award from NASA is both encouraging (an experienced third-party doesn't think the gamble's odds are too bad), hilarious (the lunar gateway station would be dwarfed by its "landing module"), and hopefully a face-saving way for NASA to loosen its ties to SLS/Orion/etc. (forcing the "old guard" to up their game). We should absolutely call out these particular billionaires for their terrible labour practices, tax dodging, market manipulation tweets, monopolising, etc. We should also call out billionaires in general for not doing enough to help the climate emergency. We should also call out governments for allowing these tax-dodgers to wield such economic power in the first place. We should also call out governments for their lacklustre climate efforts. And so on. Yet criticising space investment is a nonsense strawman.
- Tade0 5y agoI found that what gets to people is how expensive obvious stuff like running water would be on Mars.
- gamblor956 5y agoAntarctica is more hospitable than Mars. The average temperature on Mars is -81 degrees F. The South Pole is generally -76 F during the Southern Winter. On top of that, Antarctica has a breathable atmosphere, and water. Mars does not have a breathable atmosphere, and if it has water, it does not have water in an easily accessible form. Mars also has 2.5x the radiation one would experience orbiting the Earth, or approximately 35x the radiation one would generally experience on Earth. We would literally have to destroy Earth before Mars becomes a more viable option for continued human existence.
- memorysafety 5y agoGood points. But dare you doubt human's destruction ability?.. Note also, that destroying just the thin tender habitable layer of Earth would suffice.
- nicoburns 5y ago> dare you doubt human's destruction ability?.. I don't doubt human's ability. Which is why I fight those who don't seem to care about preserving earth. Who seem to overlap quite strongly woth those who believe that other planets may provide a viable alternative. I don't doubt our ability to destroy earth, but I do doubt our ability to successfully live somewhere else.
- memorysafety 5y agoI might be a counterexample to your perceived overlap. 3 points: * It seems that, as a species, we have deep issues rooted in our tribal upbringing. Reaching a global actionable consensus seems as hard (if not harder) as colonizing another planet. The internet only catalyzes the "us vs they" thinking people struggle to get rid of. In one of its many incarnations, it's a nurture of horribly mistaken worldviews — and here I imply climate change denialism, in context. But also flat earth, etc. * Viewed independently from antropogenic climate change catastrophy -- living on another planet would be extraordinary achievement, would you disagree? Launching a "toy" helicopter is kinda cool, but... living? For some of our greatest ancestors, the coolest achievement has been building millenia-lasting megastructures. Our generations are building fusion testbeds, orbital telescopes & commsat constellations; why wouldn't, say, a giant Earth-shaped globe monument on Mars be great? Perhaps not a globe, yea... but a Statue Of Liberty? Dao temple maybe? A hammer-and-sickle impact crater giga-egraving? Whatever. * Both viewed together, rationally, Mars colonization is an option to escape extinction on Earth. Not a priority, sure; more like, a backup-of-backup-of-backup plan -- for when all else failed (see point 1). It's not like we can do it soon, either; advance preparations and long practice needed. I won't express any judgement of viability. I do see, however, how ambition and inter-tribe competition can drive this plan to a ready state (see point 2) -- sooner than fossil fuel combustion stops across the world.
- Xplune13 5y agoI always find these types of comments funny. I cannot think of any other reason on why a person would think that going to mars is a better option than lack of research on the planet and its habitability. On top of that, going to Mars isn't going to magically solve the problems. As I've said earlier in some past comment, going to Mars is just as good as moving the goalpost. What we have to do is change what we're currently doing to planet Earth rather that going someplace else and thinking that we've passed all the problems that are in our thinking. I'm all for space exploration, but saying "I'm going to Mars to run from any problems" is just laughable in my opinion.
- grey-area 5y agoThe reason for going to Mars is not to avoid mankind’s mistakes (e.g. global warming) but to avoid the great filter in whatever form it takes.
- Xplune13 5y agoYes, that's what I meant when I said I'm all for space exploration. But, most of the reasons to leave the planet Earth from us general public have been in the line of "I'm fed up with all this and that's why I have to go to the Mars to start anew" i.e. mostly running away from the problems or fed up of the system etc. That being said, in my opinion, we should definitely pay more attention to saving this planet rather than finding new ones and doing the same thing all over again.
- grey-area 5y agoI sincerely think we do pay more attention to this planet than Mars, e.g. many people advocating mars are also involved in electric cars and solar energy.
- AnIdiotOnTheNet 5y agoYeah, I agree. Mars is so utterly inhospitable that even the worst apocalypses the earth has ever seen (since it has cooled anyway) leave it orders of magnitude more hospitable. Going to mars and learning how to live there is certainly valuable, but it is definitely not a solution to earth's environmental problems.
- jefurii 5y agoSo what you're saying is you'd like to die a few months or possibly years later than everybody else, but on a different planet?
