Available in PDF, EPUB and Kindle. Book excerpt: A counterintuitive and compelling argument that existing laws already protect the entirety of our oceans—and a call to understand and enforce those protections. The world’s oceans face multiple threats: the effects of climate change, pollution, overfishing, plastic waste, and more. Confronted with the immensity of these challenges and of the oceans themselves, we might wonder what more can be done to stop their decline and better protect the sea and marine life. Such widespread environmental threats call for a simple but significant shift in reasoning to bring about long-overdue, elemental change in the way we use ocean resources. In Future Sea, ocean advocate and marine-policy researcher Deborah Rowan Wright provides the tools for that shift. Questioning the underlying philosophy of established ocean conservation approaches, Rowan Wright lays out a radical alternative: a bold and far-reaching strategy of 100 percent ocean protection that would put an end to destructive industrial activities, better safeguard marine biodiversity, and enable ocean wildlife to return and thrive along coasts and in seas around the globe. Future Sea is essentially concerned with the solutions and not the problems. Rowan Wright shines a light on existing international laws intended to keep marine environments safe that could underpin this new strategy. She gathers inspiring stories of communities and countries using ocean resources wisely, as well as of successful conservation projects, to build up a cautiously optimistic picture of the future for our oceans—counteracting all-too-prevalent reports of doom and gloom. A passionate, sweeping, and personal account, Future Sea not only argues for systemic change in how we manage what we do in the sea but also describes steps that anyone, from children to political leaders (or indeed, any reader of the book), can take toward safeguarding the oceans and their extraordinary wildlife.

Available in PDF, EPUB and Kindle. Book excerpt: Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.

Book excerpt: Nobel Prize winner Al Gore wrote of Deborah Cramer's previous book Great Waters, "I urge everyone to read this book, to act on its message, and to pass on its teachings." Now Cramer offers a groundbreaking book for an even more urgent time. Our lives depend on the sea. As gifted science writer Deborah Cramer makes clear in this extraordinary volume, the ocean has been earth's lifeline for more than three and a half billion years. Life began in the scalding inferno of deep-sea hot springs. The first cell, the first plant, and the first animal were all born in the sea. Climate changes wrought by the sea created evolutionary pathways for mammals and gave rise to our human ancestors some 200,000 years ago. The one, interconnected sea still sustains us. Invisible plants in the ocean's sunlit surface give us air to breathe. Rushing currents supply water to the atmosphere's protective greenhouse and rain to dry land. But as Cramer reveals in this sweeping look at earth's biography, the vital partnership between earth and the life it nourishes has recently been disrupted. Today, a single terrestrial species, man, has begun to alter the health of the sea itself. The mark of humans on the seas is now everywhere—from the fertile waters of continental shelves to the icy reaches of the poles, from the dazzling diversity of coral reefs to the porous edge of estuaries. Even the open ocean bears clear traces of our harmful ways. Scientists believe human impact may have already sparked a catastrophic event that could change the sea and the earth irrevocably: the sixth mass planetary extinction on a scale unseen since the demise of the dinosaurs 65 million years ago. But unlike the forces that caused previous extinctions, humankind can make a choice. We can choose the mark we wish to make and the legacy we leave behind. Written in the passionate tradition of Rachel Carson, Smithsonian Ocean is at once a book for our time and for the ages. Carson wrote: "One way to open your eyes is to ask yourself: What if I had never seen this before? What if I knew I would never see it again?" Cramer's powerful and inspiring message is equally a wake-up call: "We hold earth's life-giving waters—and our future—in our hands." Our lives depend on the sea.

This book was released on 2019-12-24 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the state of our knowledge on the interactions between climate change and marine biota. It focusses broadly on the environmental stressors during the Anthropocene period; when human activities started to have a significant global impact on earth's geological imprint and ecosystems. This period of rapid change is accompanied by rising carbon dioxide levels, increasing global temperatures, loss of oxygen in aquatic systems, and the fast release of pollutants into the environment among many other environmental stressors originating from large scale human activities, such as widespread overfishing.The Future of Marine Life in a Changing Ocean starts by providing the reader with a brief background on fundamental concepts in ocean science and climate. It then moves on to a brief description of recent changes in marine chemistry such as ocean acidification, a decline in oxygen levels in the oceans, ocean warming, and marine pollution, with some examples of shifts in ecosystem diversity. The chapters discuss these topics in the context of how a changing ocean impacts ecosystem health, the biological carbon pump, the sequestration of carbon dioxide from the surface ocean into the deep sea, and the perceived notion of the ocean's unlimited resilience to maintain its role as a 'carbon reservoir'. Topics include threats to marine diversity, ecosystem function, latitudinal shifts in productivity and diversity, and changes in global cycling of elements such as carbon. It concludes with an analysis of the impact of climate change on food security.Written for undergraduate and graduate students, and researchers in the natural and social sciences, this book provides a science background to study environmental change in marine ecosystems as well as a science framework to study policy, marine law and the economics of climate change. This book is an essential read for anyone hoping to understand key challenges facing our oceans.

Book excerpt: One of Library Journal’s 10 Best Books of 2015 Following his acclaimed Atlantic and The Men Who United the States, New York Times bestselling author Simon Winchester offers an enthralling biography of the Pacific Ocean and its role in the modern world, exploring our relationship with this imposing force of nature. As the Mediterranean shaped the classical world, and the Atlantic connected Europe to the New World, the Pacific Ocean defines our tomorrow. With China on the rise, so, too, are the American cities of the West coast, including Seattle, San Francisco, and the long cluster of towns down the Silicon Valley. Today, the Pacific is ascendant. Its geological history has long transformed us—tremendous earthquakes, volcanoes, and tsunamis—but its human history, from a Western perspective, is quite young, beginning with Magellan’s sixteenth-century circumnavigation. It is a natural wonder whose most fascinating history is currently being made. In telling the story of the Pacific, Simon Winchester takes us from the Bering Strait to Cape Horn, the Yangtze River to the Panama Canal, and to the many small islands and archipelagos that lie in between. He observes the fall of a dictator in Manila, visits aboriginals in northern Queensland, and is jailed in Tierra del Fuego, the land at the end of the world. His journey encompasses a trip down the Alaska Highway, a stop at the isolated Pitcairn Islands, a trek across South Korea and a glimpse of its mysterious northern neighbor. Winchester’s personal experience is vast and his storytelling second to none. And his historical understanding of the region is formidable, making Pacific a paean to this magnificent sea of beauty, myth, and imagination that is transforming our lives.

Book excerpt: Containing 97 percent of Earth's water supply, the ocean plays a huge role in regulating global temperatures, supporting plant and animal life, and contributing to the livelihoods of millions of people. But in spite of all this, the ocean remains drastically unexplored, and the details of its impact on human lives aren't fully understood. Scientists from around the world are realizing that to address issues plaguing the ocean, such as dead zones, coral bleaching, and climate change, we need to better understand this incredible, unique feature of our planet. With a range of impressive, cutting-edge technologies at their disposal, oceanographers have set out to measure, sample, and analyze at every turn. Every day, mysteries about the ocean are being solved, and every day, new questions come to light. The more scientists learn, the better they are able to answer these new questions. What lies in the deep? And who is at the forefront of these exciting discoveries? The scientists and research included in this book shed light on the most pressing issues currently facing oceanographers and point us in the right direction to solving these challenges.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the scientific and popular media have been bombarded by gloom and doom stories of the future of fisheries, the status of fish stocks, and the impact of fishing on marine ecosystems. Dozens of certification and labeling schemes have emerged to advise consumers on what seafood is sustainable. In recent years, an opposing narrative has emerged emphasizing the success of fisheries management in many places, the increasing abundance of fish stocks in those places, and the prescription for sustainable fisheries. However, there has been no comprehensive survey of what really constitutes sustainability in fisheries, fish stock status, success and failures of management, and consideration of the impacts of fishing on marine ecosystems. This book will explore very different perspectives on sustainability, and bring together the data from a large number of studies to show where fish stocks are increasing, where they are declining, the consequences of alternative fisheries management regimes, and what is known about a range of fisheries issues such as the impacts of trawling on marine ecosystems. Ocean Recovery is aimed principally at a general audience that is already interested in fisheries but seeks both a deeper understanding of what is known about specific issues and an impartial presentation of all the data rather than selected examples used to justify a particular perspective or agenda. It will also appeal to the scientific community eager to know more about marine fisheries and fishing data, and serve as the basis for graduate seminars on the sustainability of natural resources.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have been marked by the decline or collapse of one fishery after another around the world, from swordfish in the North Atlantic to orange roughy in the South Pacific. While the effects of a collapse on local economies and fishing-dependent communities have generated much discussion, little attention has been paid to its impacts on the overall health of the ocean's ecosystems. In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean presents the first empirical assessment of the status of ecosystems in the North Atlantic ocean. Drawing on a wide range of studies including original research conducted for this volume, the authors analyze 14 large marine ecosystems to provide an indisputable picture of an ocean whose ecology has been dramatically altered, resulting in a phenomenon described by the authors as "fishing down the food web." The book: provides a snapshot of the past health of the North Atlantic and compares it to its present status presents a rigorous scientific assessment based on the key criteria of fisheries catches, biomass, and trophic level considers the factors that have led to the current situation describes the policy options available for halting the decline offers recommendations for restoring the North Atlantic An original and powerful series of maps and charts illustrate where the effects of overfishing are the most pronounced and highlight the interactions among various factors contributing to the overall decline of the North Atlantic's ecosystems. This is the first in a series of assessments by the world's leading marine scientists, entitled "The State of the World's Oceans." In a Perfect Ocean: The State of Fisheries and Ecosystems in the North Atlantic Ocean is a landmark study, the first of its kind to make a comprehensive, ecosystem-based assessment of the North Atlantic Ocean, and will be essential reading for policymakers at the state, national, and international level concerned with fisheries management, as well for scientists, researchers, and activists concerned with marine issues or fishing and the fisheries industry.
