A masterwork of journalism . . . The theme is profound: Life does not simply exist on Earth; it is Earth . . . Jabr has the curiosity of a reporter, the mind of a scientist, and the lyricism of a poet . . . Popular science writing at its very best' – Kirkus Reviews, starred review A radically thought-provoking account of a major shift in how we understand our Earth, not simply as an inanimate planet on which life evolved, but rather as a planet that came to life. The notion of a living world is one of humanity’s oldest beliefs. Though once scorned by many scientists, the concept of Earth as a vast interconnected living system has gained acceptance in recent decades. Life not only adapts to its surroundings – it also shapes them in dramatic and enduring ways. Over billions of years, life transformed a lump of orbiting rock into our cosmic oasis, breathing oxygen into the atmosphere, concocting the modern oceans, and turning rock into fertile soil. Life is intertwined with Earth’s capacity to regulate its climate and maintain balance. Through compelling narrative, evocative descriptions, and lucid explanations, Ferris Jabr shows us how Earth became the world we’ve known, how it is rapidly becoming a very different world, and how we will determine what kind of Earth our descendants inherit for millennia to come. 'Jabr has an uncanny ability to explore and explain some of the greatest mysteries of the universe, and his sentences are both luscious and limpid. He is an exceptional new science writer, and this urgent book is poised to influence larger conversations about the environment.' – Jury of the Whiting Foundation Grants for Creative Non-Fiction
