James Lovelock proposes that all living species are components of that organism, as cells are components of the human body.

Gaia, in which James Lovelock puts forward his inspirational and controversial idea that the Earth functions as a single organism, with life influencing planetary processes to form a self-regulating system aiding its own survival, is now a classic work that continues to provoke heated scientific debate.

This classic work is reissued with a new preface by the author. Written for non-scientists the idea is put forward that life on Earth functions as a single organism.

Since James Lovelock's first book, Gaia, was published, much scientific work has confirmed his theory that the Earth and all living things are part of one great organism. The Ages of Gaia looks at this evidence in detail and has been updated and revised throughout in this second edition. In his discussion of scientific and environmental issues he sounds a warning of the damage man is doing to the health of the planet.

The creator of the Gaia theory--that the Earth is a living organism--applies the traditional medical disciplines to ecological problems and solutions; here are anatomy, biochemistry, metabolism, etc. Brightly illustrated with color (mostly stylized drawings) on nearly every page, to appeal to the general reader, armchair ecoterrorist, and science fiction fan. No bibliography. Annotation copyrighted by Book News, Inc., Portland, OR

A critical examination of James Lovelock's controversial Gaia hypothesis One of the enduring questions about our planet is how it has remained continuously habitable over vast stretches of geological time despite the fact that its atmosphere and climate are potentially unstable. James Lovelock's Gaia hypothesis posits that life itself has intervened in the regulation of the planetary environment in order to keep it stable and favorable for life. First proposed in the 1970s, Lovelock's hypothesis remains highly controversial and continues to provoke fierce debate. On Gaia undertakes the first in-depth investigation of the arguments put forward by Lovelock and others—and concludes that the evidence doesn't stack up in support of Gaia. Toby Tyrrell draws on the latest findings in fields as diverse as climate science, oceanography, atmospheric science, geology, ecology, and evolutionary biology. He takes readers to obscure corners of the natural world, from southern Africa where ancient rocks reveal that icebergs were once present near the equator, to mimics of cleaner fish on Indonesian reefs, to blind fish deep in Mexican caves. Tyrrell weaves these and many other intriguing observations into a comprehensive analysis of the major assertions and lines of argument underpinning Gaia, and finds that it is not a credible picture of how life and Earth interact. On Gaia reflects on the scientific evidence indicating that life and environment mutually affect each other, and proposes that feedbacks on Earth do not provide robust protection against the environment becoming uninhabitable—or against poor stewardship by us.

Examines the causes and effects of global warming and offers opinions from leading scientists about what can be done to help the Earth.
