Earth has been the perfect sanctuary for millions of years—a pale blue dot suspended in a cosmic void that is otherwise cold, silent, and hostile to life. However, as we look toward the deep future and the accelerating changes in our environment, a chilling question begins to haunt our species: How much longer will humans be able to survive on Earth? Our planet is a finite stage, and the biological clock of our civilization is ticking against the relentless backdrop of astronomical cycles and our own impact on the biosphere. From the inevitable brightening of the Sun to the depletion of life-sustaining resources, the window of habitability for our kind is not as eternal as it once seemed.
