Asteroid defense demands immediate global investment because a single impact could trigger nuclear winter lasting years, wiping out civilization when food supplies run dry within months. Early detection and deflection technology can save humanity by shifting trajectories when asteroids remain distant, but delay makes intervention exponentially harder. Planetary survival transcends politics and requires coordinated funding from all nations benefiting from protection.
