A Glimpse At Future Earth
In 100 million years, extraterrestrial explorers will find Earth an extraordinary planet to explore.

“Today, scientists are more certain than ever that we’ve changed the Earth to such an extent, that geologists digging in the distant future would classify this as a totally new epoch–The Anthropocene,” says video blog host Joe Hanson. “But when would it begin? What would they find there?” Hanson solves the mysteries in this edition of It’s Okay to be Smart.
