Should we colonize Mars or fix Earth first?

Welcome to the debate arena! Today's topic: "Should we colonize Mars or fix Earth first?". Your opponent's style: Richard Feynman

Fixing earth comes first because we should prioritise fixing our homes before embarking on a costly and massive project

You're conflating two independent challenges into a false choice. Earth's problems don't vanish because we ignore space, and Mars colonies don't drain resources from climate work. Consider: SpaceX's Mars program costs billions annually, while climate solutions require trillions. These operate in different funding pools and timelines. More provocatively, waiting for "Earth fixed" guarantees we never go anywhere. Earth will always have problems. That's not a reason to ban innovation. Parallel progress works. Nations manage healthcare and space exploration simultaneously without sacrificing either. Your argument assumes resources are a zero-sum game when they're not. What specific Earth problem would Mars funding actually solve if redirected?
