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.

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.

The Negev , first published over a decade ago, told the story of some twenty years of study of southern Israel's desert. It synthesized the findings of botanists, geologists, soil scientists, agronomists, archaeologists, historians, and engineers and told how the applications of their work produced an agricultural surplus in this forbiddingly dry, hot region. , Now Michael Evenari has amplified the book with data from another decade of work. He describes the efforts at a new farm at Wadi Mashash, extends the weather data another ten years, presents further work on the adaptations of plants and animals to desert conditions, and takes a much deeper look at the historical precedents for the method of runoff agriculture, which has made the desert bloom.
