Earth is destined for disaster. This is a good 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.
That’s why scientists at the University of Arizona are proposing a far-out concept that just might save us all: a 21st-century version of Noah’s Ark … on the moon.
This ark wouldn’t contain two of every animal, but rather, a repository of cryogenically frozen reproductive cells from 6.7 million species on our planet.
