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.focusing on four key natural forces - global weather systems distributing fresh water to all corners; marine currents delivering nutrients to the deepest reaches of the ocean; solar energy warming and electrifying everything it touches; and volcanic activity fertilising the earth's surface - huw cordey reveals to us new levels of this living world, a place populated with astonishing characters living remarkable lives. from arctic wolves prowling moonlit landscapes or wood frogs, frozen in winter and magically thawing back to life, to flamingos flying thousands of miles to a vast volcanic lake in africa to breed, we see time and again how animals are perfectly adapted to whatever the environment throws at them.packed with over 250 full-colour images, and including a foreword by alastair fothergill and stills from the bbc series' spectacular footage, a perfect planet is a stunning exploration of life on earth - life that is increasingly precious and rare.
