Scientists Are Planning to Build Noah's Ark on the Moon
Courtney Linder
Humans, plants, and animals on Earth face the dual threats of climate change and asteroids someday striking the planet.
Scientists believe they can preserve all living things with a solar-powered lunar ark.
This compound inside the moon's lava tubes could store cryogenically frozen reproductive cells from 6.7 million species on Earth as a sort of insurance policy.
In 2013, a cataclysmic meteor the size of a six-story building broke apart above Chelyabinsk, Russia, and the resulting blast was stronger than a nuclear explosion. In 2068, astronomers believe a potentially hazardous "God of Chaos" asteroid could slam into Earth. Both events suggest humans—and every other animal and plant on Earth—are much more susceptible to total annihilation than we think.
