Gaia by James Lovelock

In this classic work that continues to inspire many readers, Jim Lovelock puts forward his idea that the Earth functions as a single organism. Written for non-scientists, Gaia is a journey through time and space in search of evidence in support of a radically different model of our planet. In contrast to conventional belief that life is passive in the face of threats to its existence, the book explores the hypothesis that the Earth’s living matter influences
air, ocean, and rock to form a complex, self-regulating system that has the capacity to keep the Earth a fit place for life.
