Review by Sid Perkins
The world could end any number of ways — and in a sense it already has, many times, in mass extinctions that paved the way for new life.
Childs, a writer, recounts field trips to nine sites that today are suffering some of the same major environmental disruptions that afflicted Earth during those extinctions or that might trigger future die-offs — places that Childs describes as “the most desolate, phenomenal and downright strange parts of the world.”
