There’s something wrong with us.

We’ve risen to prominence on a world that’s positively “rippling with life,” as Carl Sagan described it. The more we study our planet, the more we find life eking out an existence in the most unlikely of places.

Yet we seem destined to drive many species to extinction, even though we see those extinctions coming from miles away.

As an indication of how serious the problem is, one group of researchers suggests we use the Moon—yes, the Moon—as a safe repository for Earth’s biodiversity.

A Distant Asteroid Collision Gave Earthly Biodiversity An Ancient Boost

About 466 million years ago, there was an asteroid collision in the asteroid belt between Mars and Jupiter. The collision caused the breakup of a major asteroid, creating a shower of dust throughout the inner Solar System. That event is called the Ordovician Meteor Event, and its dust caused an ice age here on Earth.

That ice age contributed to an enormous boost in biodiversity on ancient Earth.
