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

we should fix earth because there isn't a planet B

You're hiding behind a truism. Yes, Earth is irreplaceable, but that's precisely why Mars colonization matters. Earth's problems aren't solved by abandoning space exploration, they're solved by redirecting resources and political will. We have both. The false binary you're positing, "fix Earth OR colonize Mars," assumes they compete for the same pool of funding. They don't. SpaceX's Mars ambitions cost billions, while climate solutions need trillions. Different magnitudes, different sources. More pointedly, a self-sustaining Mars colony creates redundancy for human civilization, ensuring no single planetary catastrophe ends us. That's not escapism, it's insurance. Why does hedging humanity's survival bet threaten your commitment to fixing Earth?
