The Unnatural History of the Sea
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 Ocean of 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.

Ocean of Life
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? And, 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; and, the oceans themselves absorb vast quantities of carbon dioxide. The life they support is now in the balance.
Coral Reef Conservation
Coral reefs are the 'rain forests' of the ocean, containing the highest diversity of marine organisms and facing the greatest threats from humans. As shallow-water coastal habitats, they support a wide range of economically and culturally important activities, from fishing to tourism. Their accessibility makes reefs vulnerable to local threats that include over-fishing, pollution and physical damage. Reefs also face global problems, such as climate change, which may be responsible for recent widespread coral mortality and increased frequency of hurricane damage. This book, first published in 2006, summarises the state of knowledge about the status of reefs, the problems they face, and potential solutions. The topics considered range from concerns about extinction of coral reef species to economic and social issues affecting the well-being of people who depend on reefs. The result is a multi-disciplinary perspective on problems and solutions to the coral reef crisis.
Reef Fisheries
Reef ecosystems extend throughout the tropics. Exploited by small-scale fishers, reefs supply food for millions of people, but, worldwide, there are growing worries about the productivity and current state of these ecosystems. Reef fish stocks display many features of fisheries elsewhere. However, habitat spatial complexity, biological diversity within and among species, ecosystem intricacy and variable means of exploitation make it hard to predict sustainable modes and levels of fishing.

Beyond the Catch
Drawing on archaeological and written sources, this collection of essays presents fascinating new interpretations in the history of the fisheries by highlighting the consequences of the northern fisheries through interdisciplinary approaches to various themes, including the environment, economy, politics, and society in the medieval and early modern periods.
Reef Life
'A ravishing, alarming account of these underwater palaces of wonder, and the existential threat they face from humanity and our warming climate ... Nature's throne rooms are thrown open by Roberts's prose' - The Spectator 'A vibrant memoir ... a fine introduction to the ecology of reefs and the existential threats they now face' - The Guardian 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 ba...
