Download or read book Coastal and Deep Ocean Pollution written by Andres Hugo Arias and published by CRC Press. This book was released on 2020-03-10 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the recent decades, social, political and academic endeavours have been made to improve environmental quality and reduce pollution. In particular, the ocean, sea and coastal areas show varying degrees of impact from the multiple human activities carried out in the terrestrial as well as in the aquatic environment. Ecology is a science which studies the relationship between organisms and the surrounding environment and in the modern era, the marine world is getting increasing attention. For centuries it has been the final reservoir of human garbage; later it became an oil farm with a concomitant increase of coastal population growth and unplanned growth of the fishing industry and the increasing use of sea routes for cargo transport and recreational uses (cruises). All this led to rising contamination with negative effects on biota and even human health. It is then imperative to know the current situation of the world's oceans: that is the main purpose of this book, to document at a glance the latest research in the field of ocean pollution.

Download or read book Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Download or read book Sustaining Wildlands written by Aaron J. Poe and published by University of Arizona Press. This book was released on 2017-11-14 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the Exxon Valdez oil tanker ran aground on Bligh Reef in Alaska in 1989 and spilled 11 million gallons of oil, it changed Prince William Sound forever. The catastrophe disrupted the region’s biological system, killing countless animals and poisoning habitats that to this day no longer support some of the local species. The effects have also profoundly altered the way people use this region. Nearly three decades later, changes in recreation use run counter to what was initially expected. Instead of avoiding Prince William Sound, tourists and visitors flock there. Economic revitalization efforts have resulted in increased wilderness access as new commercial enterprises offer nature tourism in remote bays and fjords. This increased visitation has caused concerns that the wilderness may again be threatened—not by oil but rather by the very humans seeking those wilderness experiences. In Sustaining Wildlands, scientists and managers, along with local community residents, address what has come to be a central paradox in public lands management: the need to accommodate increasing human use while reducing the environmental impact of those activities. This volume draws on diverse efforts and perspectives to dissect this paradox, offering an alternative approach where human use is central to sustaining wildlands and recovering a damaged ecosystem like Prince William Sound.

Book excerpt: Water is more important than ever before. It is increasingly controversial in direct proportion to its scarcity, demand, neglect, and commodification. There is no place on the planet where water is not, or will not be, of critical concern. Signs of Water brings together scholars and experts from five continents in an interdisciplinary exploration of the theoretical approaches, social and political issues, and anthropogenic hazards surrounding water in the twenty-first century. From the kitchen taps of Detroit, Michigan to the water-harvesting infrastructure of Tokyo, from the Upper Xingu Basin of Brazil to the Sunda Deep of the Java Trench, these essays flow through time and place to uncover the many issues surrounding water today. Asking key theoretical questions, exposing threats to vital water systems, and proposing paths forward, Signs of Water brims with histories, ontologies, and political struggles. Bringing together local experiences to tell a global story, it centers water as history, as politics, and as a human right.

Book excerpt: 2018 Foreword INDIES Book of the Year Awards Finalist in Nature The 2.1 million acres (equivalent to Yellowstone National Park) of the wilderness study area are coming under increasing threat by resource development Essays of personal explorations of the region by an award-winning writer are accompanied by dramatic images from an award-winning photographer The wilderness study area is home to the largest concentration of tidewater glaciers in America and hosts a vast diversity of terrestrial and aquatic mammals, birds, and fish It's been said that "a picture is worth a thousand words," and nowhere is that more true than on the pages ofA Wild Promise: Prince William Sound. The images of photographer Hugh Rose show you what this region holds--and what will be lost without protection from future resource development. Alongside Hugh's images are eloquent essays covering the natural and cultural history, people, and fragility of this region by noted Alaskan writer Debbie Miller. Alaska's famed Prince William Sound includes more than 3,000 shore land miles of bays, coves, and deep fjords topped by the ice-capped peaks of the Chugach Mountains. More than 1 million tourists visit the region annually, and small family-owned fishing boats, ecotourism, oyster farms, and guide services provide sustainable livelihoods for year-round Alaskan residents. Many Americans first came to know of Prince William Sound through the Exxon Valdez oil spill of 1989--a catastrophe with lingering long-term effects, such the collapse of the once abundant herring population, a critical fish in the marine food chain. InA Wild Promise, readers travel alongside Hugh and Debbie as they hike and kayak from Columbia Glacier to College Fiord, exploring the Nellie Juan-College Fjord Wilderness Study Area, a region set aside for study in 1980, to be followed--it was hoped--by permanent protection from Congress. After almost four decades of being in limbo as a designated wilderness study area, the fate of this spectacular, wild place is now in our hands. Its protection is a gift we can offer generations to come--a promiseof wilderness, beauty, and natural diversity that we can, indeed, keep.

Download or read book Haa L elk w H s Aan Saax written by Thomas F. Thornton and published by University of Washington Press. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Haa Leelk'w Has Aan' Saaxu / Our Grandparents' Names on the Land presents the results of a collaborative project with Native communities of Southeast Alaska to record indigenous geographic names. Documenting and analyzing more than 3,000 Tlingit, Haida, and other Native names on the land, it highlights their descriptive force and cultural significance. With community maps, tables, and photographs, this book will be invaluable for those seeking to understand Alaska Native geographic perspectives. As Tlingits from the Hoonah Indian Association explain in the book: "Long before Russian, French, Spanish, and British explorers mapped and named the mountains and bays of the Huna Tlingit homeland, we identified special places in our own vibrant, descriptive ways. Tlingit place names reflect important natural resources, ancestral stories, sacred places, and major geological and historic events. Our place names describe more than just inanimate locations for we perceive the mountains, glaciers, and streams to be as alive and aware as ourselves. Rather, they capture the history, emotions, and stories of our enduring relationship with a living, evolving landscape." "The new benchmark against which all future work will be measured." -Richard Dauenhauer, author of Russians in Tlingit America "Thomas Thornton and his Tlingit colleagues show how 'grandparents' names on the land' provide exquisite scaffolding for human ecologies in North America's far northwest--a moral universe inhabited by a community of beings in constant communication and exchange. This book will be a resource for the ages." -Julie Cruikshank, author of Do Glaciers Listen? Local Knowledge, Colonial Encounters, and Social Imagination "Restoring Tlingit placenames and their meanings will root our people back in place and decolonize the landscape, and Thornton has provided us with a fundamental tool to do exactly that. Sh t--oghaa xhat ditee--I am grateful." -Lance A. Twitchell, Xh'unei, University of Alaska Southeast Thomas F. Thornton is senior research fellow and director of the Environmental Change and Management Program at the Environmental Change Institute, School of Geography and the Environment, University of Oxford He is the author of Being and Place among the Tlingit.
