Humanity can make short work of the oceans’ creatures. In 1741, hungry explorers discovered herds of Steller’s sea cow in the Bering Strait, and in less than thirty years, the amiable beast had been harpooned into extinction. It’s a classic story, but a key fact is often omitted. Bering Island was the last redoubt of a species that had been decimated by hunting and habitat loss years before the explorers set sail. As Callum M. Roberts reveals in The Unnatural History of the Sea, the oceans’ bounty didn’t disappear overnight. While today’s fishing industry is ruthlessly efficient, intense exploitation began not in the modern era, or even with the dawn of industrialization, but in the eleventh century in medieval Europe. Roberts explores this long and colorful history of commercial fishing, taking readers around the world and through the centuries to witness the transformation of the seas. Drawing on firsthand accounts of early explorers, pirates, merchants, fishers, and travelers, the book recreates the oceans of the past: waters teeming with whales, sea lions, sea otters, turtles, and giant fish. The abundance of marine life described by fifteenth century seafarers is almost unimaginable today, but Roberts both brings it alive and artfully traces its depletion. Collapsing fisheries, he shows, are simply the latest chapter in a long history of unfettered commercialization of the seas. The story does not end with an empty ocean. Instead, Roberts describes how we might restore the splendor and prosperity of the seas through smarter management of our resources and some simple restraint. From the coasts of Florida to New Zealand, marine reserves have fostered spectacular recovery of plants and animals to levels not seen in a century. They prove that history need not repeat itself: we can leave the oceans richer than we found them.

A Silent Spring for oceans, written by "the Rachel Carson of the fish world" (The New York Times) Who can forget the sense of wonder with which they discovered the creatures of the deep? In this vibrant hymn to the sea, Callum Roberts—one of the world’s foremost conservation biologists—leads readers on a fascinating tour of mankind’s relationship to the sea, from the earliest traces of water on earth to the oceans as we know them today. In the process, Roberts looks at how the taming of the oceans has shaped human civilization and affected marine life. We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

The Newfoundland and Labrador cod fishery was once the most successful commercial fishery in the world. When it collapsed in 1992, many pointed to failures in management, such as uncontrolled harvesting, as likely culprits. Managed Annihilation makes the case that the idea of natural resource management itself was the problem. The collapse occurred when the fisheries were state-managed and still, two decades later, there is no recovery in sight. Although the collapse raised doubts among policy-makers about their ability to understand and control nature, their ultimate goal of control through management has not wavered and has been transferred from wild fish to fishermen and farmed cod.

A three-thousand-year history of the Yellow River and the legacy of interactions between humans and the natural landscape From Neolithic times to the present day, the Yellow River and its watershed have both shaped and been shaped by human society. Using the Yellow River to illustrate the long-term effects of environmentally significant human activity, Ruth Mostern unravels the long history of the human relationship with water and soil and the consequences, at times disastrous, of ecological transformations that resulted from human decisions. As Mostern follows the Yellow River through three millennia of history, she underlines how governments consistently ignored the dynamic interrelationships of the river’s varied ecosystems—grasslands, riparian forests, wetlands, and deserts—and the ecological and cultural impacts of their policies. With an interdisciplinary approach informed by archival research and GIS (geographical information system) records, this groundbreaking volume provides unique insight into patterns, transformations, and devastating ruptures throughout ecological history and offers profound conclusions about the way we continue to affect the natural systems upon which we depend.

For such simple garments, hats have had a devastating impact on wildlife throughout their long history. Made of wild-caught mammal furs, decorated with feathers or whole stuffed birds, historically they have driven many species to near extinction. By the turn of the twentieth century, egrets, shot for their exuberant white neck plumes, had been decimated; the wild ostrich, killed for its feathers until the early 1900s, was all but extirpated; and vast numbers of birds of paradise from New Guinea and hummingbirds from the Americas were just some of the other birds killed to decorate ladies’ hats. At its peak, the hat trade was estimated to be killing 200 million birds a year. At the end of the nineteenth century, it was a trade valued at £20 million (over $25 million) a year at the London feather auctions. Weight for weight, exotic feathers were more valuable than gold. Today, while no wild birds are captured for feather decoration, some wild animals are still trapped and killed for hatmaking. A fascinating read, Hats will have you questioning the history of your headwear.

Throughout the four hundred thousand years that humanity has been collecting fossils, sea urchin fossils, or echinoids, have continually been among the most prized, from the Paleolithic era, when they decorated flint axes, to today, when paleobiologists study them for clues to the earth’s history. In The Star-Crossed Stone, Kenneth J. McNamara, an expert on fossil echinoids, takes readers on an incredible fossil hunt, with stops in history, paleontology, folklore, mythology, art, religion, and much more. Beginning with prehistoric times, when urchin fossils were used as jewelry, McNamara reveals how the fossil crept into the religious and cultural lives of societies around the world—the roots of the familiar five-pointed star, for example, can be traced to the pattern found on urchins. But McNamara’s vision is even broader than that: using our knowledge of early habits of fossil collecting, he explores the evolution of the human mind itself, drawing striking conclusions about humanity’s earliest appreciation of beauty and the first stirrings of artistic expression. Along the way, the fossil becomes a nexus through which we meet brilliant eccentrics and visionary archaeologists and develop new insights into topics as seemingly disparate as hieroglyphics, Beowulf, and even church organs. An idiosyncratic celebration of science, nature, and human ingenuity, The Star-Crossed Stone is as charming and unforgettable as the fossil at its heart.
