The Medea Hypothesis – Is Life on Earth Ultimately Self–Destructive?: Is Life on Earth Ultimately Self-Destructive? (Science Essentials)

"A provocative look at the history of our living planet. Ward offers a distinct perspective and argues strongly that the only intelligent choice is to manage ourselves and the environment. The Medea Hypothesis will cause anyone who cares about the environment to think differently."--Thomas E. Lovejoy, president of the H. John Heinz III Center for Science, Economics, and the Environment

"This book casts the environmental debate in a completely new and important light. Ward demolishes the comfortable illusion that nature will take care of us if we just let it. To survive in the long term, the Earth needs a management team--we humans have to take up the job."--Chris McKay, NASA Ames Research Center

"The Medea Hypothesis is provocative, extremely well-written, and very convincing."--Simon A. Levin, Princeton University

"For those comforted by the notion of a benevolent Gaia working to sustain life on the planet, Ward's Medea is a nightmare, one that has recurred many times in Earth's history and is coming again soon, unless we take action to combat the self-annihilating tendency of the biosphere."--Lee R. Kump, coauthor of Dire Predictions: Understanding Global Warming

"Serious and well written, The Medea Hypothesis is sure to generate controversy among the experts. I read it over a weekend and could hardly put it aside until I finished it."--Francisco J. Ayala, University of California, Irvine

"This is an important and significant contribution to the fields of geobiology and astrobiology because it offers a startling new interpretation of the nature of Darwinian evolution. Ward's conclusion is both troubling and provocative: life may be its own worst enemy. Like James Lovelock's Gaia hypothesis, Ward's Medea hypothesis is likely to be debated for the next thirty years."--Joseph L. Kirschvink, California Institute of Technology

"A provocative rethinking of the coevolution of life and its environment. Peter Ward mounts a sustained critique of optimizing/homeostatic Gaia, providing a lucid set of examples of significant positive feedbacks arising from life. This book will have a strong heuristic impact on future research."--David Schwartzman, author of Life, Temperature, and the Earth
