Mycket gott skick. Complete text of the original hardcover. Lovelock presents the theory that the earth is a living organism and draws expertly from chemistry, biology, geology, paleontology, physics, and meteorology that life has evolved not just by adapting to its surroundings but by taking control of them and remaking them into an immense life-sustaining organism.
