The third planet from the sun is mankind's home - but how well do you know it? Its molten core, for instance, is hotter than the surface of the sun. Now, TIME presents an unrivaled portrait of Planet Earth: its violent history, its vast oceans, its constantly changing geology, its life-sheltering atmosphere, its fascinating life forms, and its imperiled climate. TIME joins scientists in the field, visits with indigenous people and consults with experts to report on the biggest story of this year and every year: Planet Earth. And we visit the Earth's extremes: the longest rivers, tallest mountains and driest deserts on the planet. This beautifully illustrated volume, featuring the work of award-winning photographers, presents a portrait of our wondrous planet--and of all the beings that call it home--that is revelatory, awe-inspiring and essential.
