    To the philosophical the  earth is eternal, while the human race -- presumptive  keeper of the world's history -- is a mere speck  in the rich stream of life. It is known that  nothing upon Earth is forever; geography, climate, and  plant and animal life are all subject to radical  change. On five occasions in the past, catastrophic  natural events have caused mass extinctions on  Earth. But today humans stand alone, in dubious  distinction, among Earth's species: Homo  Sapiens possesses the ability to destroy  entire species at will, to trigger the sixth  extinction in the history of life. In The Sixth  Extinction, Richard Leakey and Roger Lewin  consider how the grand sprawl of human life is  inexorably wreaking havoc around the world. The  authors of Origins and  Origins Reconsidered, unimpeachable  authorities on the human fossil record, turn their  attention to the most uncharted anthropological territory  of all: the future, and man's role in defining it.  According to Leakey and Lewin, man and his  surrounding species are end products of history and  chance. Now, however, humans have the unique  opportunity to recognize their influence on the global  ecosystem, and consciously steer the outcome in order  to avoid triggering an unimaginable upheaval.From the Hardcover edition.

    Buchmann, one of the world's leading authorities on bees and pollination, and Gary Paul Nabhan, award-winning writer and renowned crop ecologist, explore the vital but little-appreciated relationship between plants and the animals they depend on for reproduction -- bees, beetles, butterflies, hummingbirds, moths, bats, and countless other animals, some widely recognized and other almost unknown.Scenes from around the globe -- examining island flora and fauna on the Galapagos, counting bees in the Panamanian rain forest, witnessing an ancient honey-hunting ritual in Malaysia -- bring to life the hidden relationships between plants and animals, and demonstrate the ways in which human society affects and is affected by those relationships. Buchmann and Nabhan combine vignettes from the field with expository discussions of ecology, botany, and crop science to present a lively and fascinating account of the ecological and cultural context of plant-pollinator relationships.More than any other natural process, plant-pollinator relationships offer vivid examples of the connections between endangered species and threatened habitats. The authors explain how human-induced changes in pollinator populations -- caused by overuse of chemical pesticides, unbridled development, and conversion of natural areas into monocultural cropland-can have a ripple effect on disparate species, ultimately leading to a "cascade of linked extinctions."

    Eighty-seven at the time of writing and an internationally renowned figure, he vividly describes expeditions to almost every part of the subcontinent, including the old Princely States, Burma, Sikkim, Tibet, Bhutan and Afghanistan. As he tells of his life as motorcyclist, timber merchant, scientist, author and decorated celebrity, a picture also emerges of pre-independent India, of Maharajas and colonial administration.

    Why does the chestnut-sided warbler sing one song before dawn and another after sunrise? Why does the brown thrasher have a repertoire of two thousand songs when the chipping sparrow has only one? And how is the hermit thrush able to sing a duet with itself, producing two sounds simultaneously to create its beautiful, flutelike melody?Stap's lucid prose distills the complexities of the study of birdsong and unveils a remarkable discovery that sheds light on the mystery of mysteries: why young birds in the suborder oscines -- the "true songbirds" -- learn their songs but the closely related suboscines are born with their songs genetically encoded. As the story unfolds, Stap contemplates our enduring fascination with birdsong, from ancient pictographs and early Greek soothsayers, who knew that bird calls represented the voices of the gods, to the story of Mozart's pet starling.In a modern, noisy world, it is increasingly difficult to hear those voices of the gods. Exploring birdsong takes us to that rare place -- in danger of disappearing forever -- where one hears only the planet's oldest music.

    Settling in at a bonobo sanctuary in Congo's capital, Vanessa and her fiancé entered the world of a rare ape with whom we share 98.7 percent of our DNA. She soon discovered that many of the inhabitants of the sanctuary - ape and human alike - are refugees from unspeakable violence, yet bonobos live in a peaceful society in which females are in charge, war is nonexistent, and sex is as common and friendly as a handshake. A fascinating memoir of hope and adventure, Bonobo Handshake traces Vanessa's self-discovery as she finds herself falling deeply in love with her husband, the apes, and her new surroundings while probing life's greatest question: What ultimately makes us human? Courageous and extraordinary, this true story of revelation and transformation in a fragile corner of Africa is about looking past the differences between animals and ourselves, and finding in them the same extraordinary courage and will to survive. For Vanessa, it is about finding her own path as a writer and scientist, falling in love, and finding a home.

    She brought the world's attention to the need to preserve The Everglades. In the Afterword, Michael Grunwald tells us what has happened to them since then. Grunwald points out that in 1947 the government was in the midst of establishing the Everglades National Park and turning loose the Army Corps of Engineers to control floods--both of which seemed like saviors for the Glades. But neither turned out to be the answer. Working from the research he did for his book, The Swamp, Grunwald offers an account of what went wrong and the many attempts to fix it, beginning with Save Our Everglades, which Douglas declared was "not nearly enough." Grunwald then lays out the intricacies (and inanities) of the more recent and ongoing CERP, the hugely expensive Comprehensive Everglades Restoration Plan.

    Awarded a major grant to conduct an exhaustive study of the deteriorating environment of the Arctic by the Pew Charitable Trusts (the first time Pew has given such a grant to a journalist), Los Angeles Times environmental reporter Marla Cone traveled across the Arctic, from Greenland to the Aleutian Islands, to find out why the Arctic is toxic.Silent Snow is not only a scientific journey, but a personal one. Whether hunting giant bowhead whales with native Alaskans who are struggling to protect their livelihood, or tracking endangered polar bears in Norway, Cone reports with an insider's eye on the dangers of pollution to native peoples and ecosystems, how Arctic cultures are adapting to this pollution, and what solutions will prevent the crisis from getting worse.

    This groundbreaking book reveals how today's global businesses can be both environmentally responsible and highly profitable.

    In this edition, each chapter presents the topic clearly and distinctly. Detailed, high-level scientific data and terminology are not included because the author believes that true knowledge consists of working concepts rather than technical facility.

    Bird-eating snakes from Australia hitchhike to Hawaii in the landing gear of airliners; disruptive European zebra mussels, riding in ships' ballast water, are infiltrating aquatic ecosystems across the United States; parasitic flies from the U.S. prey on Darwin's finches in the Galapagos. Predatory American jellyfish in Russia; toxic Japanese plankton in Australia; Burmese pythons in the Everglades-biologists refer fearfully to "the homogenization of the world" as alien species jump from place to place and increasingly crowd native and endangered species out of existence. Never mind bulldozers and pesticides: the fastest-growing threat to biological diversity may be nature itself. "Out of Eden" is a journey through this strange and shifting landscape. The author tours the front lines of ecological invasion--in Hawaii, Tasmania, Guam, San Francisco; in lush rainforests, through underground lava tubes, on the deck of an Alaska-bound oil tanker--in the company of world-class scientists. Wry and reflective, animated and richly reported, "Out of Eden" is a search both for scientific answers and for ecological authenticity.
