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.

The Unnatural History of the Sea

A vibrant tribute to the sea by a leading conservation biologist traces the human race's relationship to the ocean, identifying the consequences of modern fishing, pollution and climate change on marine life while making urgent recommendations for reversing damage.

Reef Life is a marine science memoir - the story of how Britain's pre-eminent marine conservation scientist, fell in love with coral reefs. Callum Roberts begins as a young university student who had never been abroad, spending a summer helping to map the unknown reefs of Saudi Arabia. From the moment he first cleared his goggles, he's never looked back, moving on to survey Sharm al-Sheikh, and from there diving and researching all over the world, including the Australia's imperilled Great Barrier Reef and the more resilient reefs of the Caribbean, in a thirty-year career. His stories are astonishing, lyrical and laced with a wonderful wry humour - and they allow us privileged access to, and understanding of, the science of our oceans and reefs. Reading this book will also commit readers to support of Callum's goal to get marine reserve status for ten percent of the world's ocean.

Reef Life

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.

An Underwater Memoir

Our seas are host to an extraordinary variety of plant and animal life, but much of it remains mysterious and great imagery is surprisingly hard to find. Alex Mustard is one of the world's leading underwater photographers and his images are so crisp and immediate that the animals seem to swim out of the water towards you. This beautiful book gathers together a selection of his award-winning images and a number of new ones to create a vivid picture of the seas and oceans and the animals that inhabit them, each chapter accompanied by a 1500 word essay and extended captions written by leading natural history writer, Professor Callum Roberts. The text addresses the issue of change in the oceans along with tales of oceanography, marine life and human history in the seas and aims to help the reader to get to know the oceans, understand how marine animals live their lives and how they have, are and may well adapt to change.

That part of the Indian Ocean bordering Saudi Arabia is a rich mosaic of coastal and marine ecosystems, both natural and man-made. Among these are coral reefs, mangroves, tidal flats, seagrasses, and other hard and soft substrata. Some ecosystems are relatively simple, while others such as the coral reefs are highly complex and among the most diverse in the Indian Ocean. The region divides into several large, semi-enclosed water bodies whose different physical characteristics result in distinct habitats. The overall aridity, extremes of water temperature, and often very high salinities have produced some of the most extreme marine climates on Earth. This book summarizes the available information on the region, then reviews the processes shaping the various marine and coastal systems. It relates patterns in marine assemblages to the strong environmental gradients and biogeographic barriers in the region. Finally, the book considers the human dimension. Some of the world's poorest and richest nations border these seas, making diverse claims on fisheries and other natural resources. The 1991 Gulf War is only the most recent of a range of impacts affecting the region. Approaches for resolving the increasing resource use conflicts are described. This volume will be of immense value to research workers, students of marine biology, and environmental managers in general, as well as to those with a particular interest in this part of the world. One of the few published works on this unique and diverse region Serves as a basic introduction to the area Provides a detailed analysis of ecosystem function Discusses human pollution and its effects

In this revelatory book, Callum Roberts uses his lifetime's experience working with the oceans to show why they are the most mysterious places on earth, their depths still largely unexplored. In The Ocean of Life we get a panoramic tour beneath the seas: Why do currents circulate the way do? Where exactly do they go? How has the chemistry of the oceans changed? How polluted are we making them? Above all, Roberts reveals the richness of their life, and how it has altered over the centuries. The oceans are now under unprecedented threat. Not only does Roberts show how we are fishing our oceans to extinction, crucially, he explains how this directly affects our lives on land. Ninety-five percent of habitable space on earth lies in the oceans, and marine plants produce half the world's oxygen; the oceans themselves absorb vast quantities of carbon dioxide. The life they support is now in the balance. The Ocean of Life should galvanise debate worldwide. Roberts shows how we can arrest and reverse the damage we are doing. Tantalisingly, it is within our grasp to restore the life of the oceans. There is still time.

Ocean of Life

A superb visual celebration of life within and beneath the world's seas and oceans.
