Earth in Human Hands

“What if life isn’t something that happens *on* a planet, but is something that happens *to* a planet? What if the planet itself is alive?” Thus begins one of the many intriguing thought exercises in astrobiologist David Grinspoon’s new book, Earth in Human Hands (available Dec. 6, 2016). David has long been a friend of the show, in large part because he possesses a unique ability to bring the geologic imagination to life. His approach to the Anthropocene draws extensively from deep time and close observations of other planets to see what we might learn about our uncomfortable situation here on Earth. If the Anthropocene is part of the geologic time table (it is), and if the geologic time table is largely defined by life (it is), then does our current situation mean something much broader in terms of planetary evolution? David chats with GenAnthro producer Miles Traer about the new book, mind-bending perspectives on time, and why the Anthropocene hopefully marks the start, and not the end, of something quite spectacular.
