On the radio program Big Picture Science, David Grinspoon recently joined a discussion about the impacts of humankind on planet Earth. Right now, the Earth is in a geological epoch known as the Holocene. However, some scientists believe we have moved into a new epoch dubbed the ‘Anthropocene,’ or the age of man.

David Grinspoon is a senior scientist at the Planetary Science Institute in Tucson, Arizona, and was the first Baruch S. Blumberg NASA-Library of Congress Chair in Astrobiology. During his time as chair, Grinspoon studied the Anthropocene, an era in which human activities are becoming a defining characteristic of the physical nature and functioning of Earth.
