"Mars colonization is technically achievable within 30–50 years, but no economic model justifies it as a solution to Earth's resource scarcity or climate crisis. The cost-per-settler ($500 billion+ for a self-sustaining colony) dwarfs equivalent investment in terrestrial infrastructure, renewable energy, or adaptation."

"Whoever plants the flag first claims legal and resource rights under the Outer Space Treaty (1967), which explicitly forbids national appropriation but leaves enforcement toothless."

"Climate adaptation costs accelerate (estimated $300–400 billion annually by 2030)"

"We're not going to Mars to live."
