A Scientist Audits the Earth (Paperback, 2nd Revised edition)

"Through a globe-circling tour of the planet, a conservation ecologist checks environmental statistics and reveals the importance of understanding where these numbers come from in order to evaluate current awareness of the planet's potential environmental peril."-Forecast Praise for the hardcover edition (published as The World According to Pimm) "Among ecologists who can apply their understanding of basic science to the modern human predicament, Stuart Pimm is one of the very best in the world today. He writes clearly, interestingly, and understandably. This book will interest literally everyone "-Jared Diamond, author of Guns, Germs, and Steel "A dazzling tour d'horizon of the twenty-first century environment. The author informs us of the approaching fate of the natural world (including our own species) with uncommon scientific authority, style, and wit."-Edward O. Wilson, Pellegrino University Professor, Emeritus, Harvard University "A born storyteller, Pimm takes us on a world tour to reveal how people are adversely affecting their environment-a tour de force in more than one sense."-Thomas E. Lovejoy, chief biodiversity advisor to the president of the World Bank Humans use 50 percent of the world's freshwater supply and consume 42 percent of its plant growth. We are liquidating animals and plants one hundred times faster than the natural rate of extinction. Such numbers should make it clear that our impact on the planet has been, and continues to be, extreme and detrimental. Yet even after decades of awareness of our environmental peril, there remains passionate disagreement over what the problems are and how they should be remedied. Much of the impasse stems from the fact that the problems are difficult to quantify. How do we assess the impact of habitat loss on various species, when we haven't even counted them all? And just what factors go into that 42 percent of biomass we are hungrily consuming? In this book, Stuart Pimm appoints himself "investment banker of the global, biological accounts," checking the environmental statistics gathered by tireless scientists in work that is always painstaking and often heartbreaking. With wit, passion, and candor, he reveals the importance of understanding where these numbers come from and what they mean. To do so, he takes the reader on a globe-circling tour of our beautiful, but weary, planet from the volcanic mountains and rainforests of Hawai'i to the boreal forests of Siberia. Stuart L. Pimm is Doris Duke Chair of Conservation Ecology at the Nicholas School of the Environment and Earth Sciences at Duke University. He is the author of more than 150 scientific papers, as well as three books, and numerous articles in publications such as New Scientist, The Sciences, Nature, and Science.
