The dinosaurs were killed during the Fifth Extinction — which scientists suspect was caused by an asteroid. Now, we are living through an epoch that many scientists describe as the Sixth Extinction, and this time, human activity is the culprit. As one scientist put it: We're the asteroid.
Elizabeth Kolbert is the author of the new book The Sixth Extinction. It begins with a history of the "big five" extinctions of the past, and goes on to explain how human behavior is creating a sixth one — including our use of fossil fuels and the effects of climate change.
This week sees the publication of The Counterfeit Agent, the 8th book in author Alex Berenson's thriller series featuring former military man and CIA recruit John Wells. Wells can kill with his bare hands, he likes to exorcise his demons in the dead of night, at breakneck speed on the back of a motorcycle — and by the way, he's converted to Islam (a plot point TV viewers are seeing on Homeland years after Berenson featured it). Even after leaving the CIA, Wells never really leaves his job.
