Book excerpt: 2013 Orion Book Award Winner 2013 Sigurd F. Olson Nature Writing Award Winner Ours is not a stable planet. It is prone to sudden, violent natural disasters and extremes of climate. In this exhilarating exploration of our globe, Craig Childs goes to where the apocalypse can be seen now. From the driest deserts of Chile, through the genetic wasteland of central Iowa, to the site of the drowned land bridge of the Bering Sea, he uncovers cataclysms that tell us what could be next: forthcoming ice ages, super volcanoes, and the conclusion of planetary life cycles. Childs delivers a sensual feast in his descriptions of the natural world, and undeniable science that reveals both the earth’s strengths and frailties. Bearing witness to the planet’s sweeping and perilous changes, he shows how we can alter the future, and how the world will live on, though humans may not survive to see it.
