Synopsis

“They deftly bring together findings from many disparate areas of science in a book that science buffs will find hard to put down.” —Publishers Weekly Science has worked hard to piece together the story of the evolution of our world up to this point, but only recently have we developed the understanding and the tools to describe the entire life cycle of our planet. Peter D. Ward and Donald Brownlee, a geologist and an astronomer respectively, are in the vanguard of the new field of astrobiology. Combining their knowledge of how the critical sustaining systems of our planet evolve through time with their understanding of how stars and solar systems grow and change throughout their own life cycles, the authors tell the story of the second half of Earth’s life. In this masterful melding of groundbreaking research and captivating, eloquent science writing, Ward and Brownlee provide a comprehensive portrait of Earth’s life cycle that allows us to understand and appreciate how the planet sustains itself today, and offers us a glimpse of our place in the cosmic order.

From The Life and Death of Planet Earth:

There's a difference between a human's life and the life of our planet. Ruth Ward, born in 1916, aged gracefully but never resembled her youth again. Hers was a one-way trip. Planets have a different trajectory-the Earth, for instance, appears to be on a round trip of sorts. If you fire a cannon straight up, the projectile climbs to a certain height, slows, stops, and then falls back to the ground. Our planet's trajectory is similar. It started as a very hot, oxygen-free world. Water, air, plants, solar energy and plate tectonics created the conditions for natural evolution, and many people assume that the cannonball of biological complexity is still arcing upward. We believe that the cannonball has already begun to drop, and that the Earth has already started a return to a hot world where life becomes less diverse, less complicated, and less abundant though time. The last life on Earth may look much like the first life-a single-celled bacterium, survivor and descendant of all that came before.
