Over the last half billion years, there have been five major mass extinctions, when the diversity of life on Earth suddenly and dramatically contracted. Scientists are currently monitoring the sixth extinction, predicted to be the most devastating since the asteroid impact that wiped out the dinosaurs. This time around the cataclysm is us. In this book the author tells us why and how human beings have altered life on the planet in a way no species has before. She provides a moving account of the disappearances of various species occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up to Lyell and Darwin, and through the present day. The sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human. -- Publisher description.

For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: humans. Climate change is only the most visible of the modifications we've made--up until this point, inadvertently--to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence. Without minimizing the challenges of the next century, Grinspoon suggests that our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective. Our species has surmounted the threat of extinction before, thanks to our innate ingenuity and ability to adapt, and there's every reason to believe we can do so again. Our challenge now is to awaken to our role as a force of planetary change, and to grow into this task. We must become graceful planetary engineers, conscious shapers of our environment and caretakers of Earth's biosphere. This is a perspective that begs us to ask not just what future do we want to avoid, but what do we seek to build? What kind of world do we want? Are humans the worst thing or the best thing to ever happen to our planet? Today we stand at a pivotal juncture, and the answer will depend on the choices we make.

"Wake up! Act! A call to address global climate change from two masters of science fiction. Isaac Asimov and Frederik Pohl are among the greatest science fiction writers who ever lived. Their talent for envisioning the future, and their clarity in writing about that future, made their novels enduring classics. In Our angry Earth, they applied those skills to a careful survey of the state of Planet Earth and the probable effect of our carbon-burning culture on it. Their cleared-eyed call to action is as fresh and timely as it was twenty-five years ago, when this book was published. The new introduction and afterword by Kim Stanley Robinson bring the book completely up to date. Robinson is one of the greatest modern SF writers, author of the bestselling Mars trilogy, the New York Times bestselling 2312, and the current climate change-focused bestseller New York 2140. He has written fiction and nonfiction about climate change for the past thirty years. In 2008, Time named Robinson a "Hero of the Environment."--Page 4 of cover.

"From the author of Losing Earth, a deeply reported and beautifully told exploration of how we live in a post-natural world"--

Periods of great social change reveal a tension between the need for continuity and the need for innovation. To comprehend these changes as history and as guideposts to the future, Peter F. Drucker has, over a lifetime, pursued a discipline that he terms social ecology. The writings brought together in The Ecological Vision define the discipline as a sustained inquiry into the man-made environment and an active effort at maintaining equilibrium between change and conservation.

The authors highlight critical environmental problems and suggest national and international measures by which the problems can be alleviated

The Sixth Extinction is a haunting account of the age in which we live. Ecologists are calling it the Sixth Great Extinction, and the world isn't losing just its ecological legacy; also vanishing is a vast human legacy of languages and our ways of living, seeing, and knowing. Terry Glavin confirms that we are in the midst of a nearly unprecedented, catastrophic vanishing of animals, plants, and human cultures. He argues that the language of environmentalism is inadequate in describing the unraveling of the vast system in which all these extinctions are actually related. And he writes that we're no longer gaining knowledge with every generation. We're losing it. In the face of what he describes as a dark and gathering sameness upon the Earth, Glavin embarks on a global journey to meet the very things we're losing (a distinct species every ten minutes, a unique vegetable variety every six hours, an entire language every two weeks) and on the way encounters some of the world's wonderful, rare things: a human-sized salmon in Russia; a mysterious Sino-Tibetan song-language; a Malayan tiger, the last of its kind; and a strange tomato that tastes just like black cherry ice cream. And he finds hope in the most unlikely places---a macaw roost in Costa Rica; a small village in Ireland; a relic community of Norse whalers in the North Atlantic; the vault beneath the Royal Botanical Garden at Kew; and the throne room of the Angh of Longwa in the eastern Himalayas. A fresh narrative take on the usual doom and gloom environmentalism, The Sixth Extinction draws upon zoology, biology, ecology, anthropology, and mythology to share the joys hidden within the long human struggle to conserve the world's living things. Here, we find hope in what's left: the absolute and stunning beauty in the Earth's last cultures and creatures.

Responding to a reawakened concern about human activities that put the Earth at peril, this report examines the measures being taken to preserve the ecological balance of this planet. It explores the greenhouse effect, the erosion of soil and the spread of the world's deserts.
