Accompanying a major 5-part BBC series presented by David Attenborough and produced by the team behind Planet Earth and Blue Planet, this volume is an exploration of the unique conditions that make life on Earth possible, and how our wildlife is perfectly adapted to its environment. There is no place like home. The conditions of Earth are not just good for life, they are perfect. Everything about our planet - its size, its distance from the Sun, its spin and tilt, its moon - is perfectly suited to our existence, and our planet's forces serve to nurture its spectacular biodiversity. 'A Perfect Planet' shows in stunning detail how Earth has always been more than the sum of its parts. Unlike any other astronomical body, it is a living world.
