If you watch this video, try to keep in mind what Carl was saying. We’re here, not somewhere else. We are tiny to the point of insignificance as far as the rest of the universe is concerned. And our pale blue dot is fragile.

Many times life has nearly been wiped from the surface of this tiny blue dot. One of the worst was the Permian Mass Extinction, which killed 95% of all species on the planet. If you haven’t heard of it, try watching this video from the BBC. This clip is the 5th of 5 parts of a show called “The Day the Earth Nearly Died”.
