David Grinspoon

Harvard Book Store welcomes award-winning author and astrobiologist DAVID GRINSPOON—author of Lonely Planets: The Natural Philosophy of Alien Life—for a discussion of his latest book, Earth in Human Hands: Shaping Our Planet's Future.

About Earth in Human Hands

For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: humans. Climate change is only the most visible of the modifications we've made—up until this point, inadvertently—to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence.

Without minimizing the challenges of the next century, Grinspoon suggests that our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective. Our species has surmounted the threat of extinction before, thanks to our innate ingenuity and ability to adapt, and there's every reason to believe we can do so again.

Our challenge now is to awaken to our role as a force of planetary change, and to grow into this task. We must become graceful planetary engineers, conscious shapers of our environment and caretakers of Earth's biosphere. This is a perspective that begs us to ask not just what future do we want to avoid, but what do we seek to build? What kind of world do we want? Are humans the worst thing or the best thing to ever happen to our planet? Today we stand at a pivotal juncture, and the answer will depend on the choices we make.

Praise

"In his wonderful writing style, Dr. Grinspoon spells it out: A single species is inducing more profound changes to our planet than any other organism in geologic history. It's us. If you have family and friends here on Earth, read this book. The Earth is in our hands." —Bill Nye "The Science Guy", New York Times bestselling author of Unstoppable: Harnessing Science to Change the World

"David Grinspoon has done it again: cracked open our universe with a scientific inquiry that is as inspiring and engaging as it is profound. Where others see inevitable catastrophe, Grinspoon sees historic opportunity. Grinspoon is a gifted storyteller and his narrative is the rare confluence of authoritative and thought-provoking science and rollicking fun. Earth in Human Hands is a must read for anyone interested in evolution, planetary science, the crisis of the environment, and human survival. Destined to be a classic." —Peter Heller, New York Times bestselling author of The Dog Stars and The Whale Warriors

"In a moving, personal journey, Grinspoon takes the reader from molten, planetary origins, past current crises like climate change, toward a destiny that our children may yet forge, standing on our shoulders." —David Brin, New York Times bestselling author of Earth and Existence
