While oceans are vast, they represent a fragile resource that must be protected if we want to protect our livelihoods and our planet. Marine pollution has been a topic of concern for a long time, and it has recently attracted the attention of scientists, environmentalists, economists, politicians and journalists in mainstream media, . Besides providing food, transportation routes and other resources, the oceans serve as a heat absorbing sink which offsets the extreme heating effects of climate change, but only to a limited degree. Pollution in marine environments such as the oceans, poses a threat to coastal communities by affecting the fauna and flora in the environment and the health of the nearby population. This has a disruptive effect on the health and economy of these communities. Marine Pollution: Current Status, Impacts and Remedies emphasizes the limitations of marine resources that relevant environments provide. Readers will find chapters on methods to assess pollution as well as important information for identifying, measuring, and remediating various pollutants. The book also covers some known pollutants (heavy metals, organic pollutants, microplastics) and ways to manage these substances. Other issues covered in the book include problems caused by invasive species, and the ecological problems caused by pollutants which affect local fauna and flora. This book will prove to be a useful resource for students, researchers, and policymakers, who are working in environmental science, marine conservation and allied fields.
There is growing concern about the state of the world's oceans. The rapid growth of human populations in coastal regions has led to increasing dependence on marine resources. Beneficial features related to food supply and life style need to be balanced against the hazards presented by microbial pathogens, chemical pollutants, and toxic algal blooms. In this book, a group of experts from a range of backgrounds review the key aspects of the marine environment in relation to human health. An initial overview explains the need for integrating a range of disciplines, from physical oceanography and marine biology to molecular biology and epidemiology. Only by this approach can we hope to predict the consequences of environmental change and exploitation of natural resources upon our coastal ecosystems and, ultimately, on society and human health. Subsequent chapters then focus on more specialized topics. Firstly, waterborne pathogens are reviewed in detail and the microbial measures and policy implications important for protecting humans from exposure are described. Next, the consumption of contaminated seafood is considered along with its implications regarding the growth of aquaculture. Priority pollutants, emerging contaminants, and plastics are investigated as are the effects of climate change on pollution. Some phytoplankton produce biotoxins which accumulate in the flesh of filter-feeders such as bivalve molluscs. This creates a health risk when the shellfish are consumed by humans. The penultimate chapter, therefore, concentrates on harmful algal blooms (HABs) and the methodologies used to safeguard human health. The book concludes by proposing a holistic systems approach, such as Integrated Coastal Zone Management, to address the interconnected scientific challenges of increased human population pressure, pollution, over-exploitation of food resources, and the urgent need for effective public health solutions to be developed from politically and environmentally meaningful policies.
This book explores the increasing impacts on the world's oceans from coastal and offshore development, overfishing, a changing climate, natural events, and other sources that are straining the health of marine ecosystems and the Great lakes. Impacts to these intricately balanced environments include declining fish populations, degradation of coral reefs and other vital habitats, threats to rare or endangered species, and loss of artefacts and resources that represent the diverse cultural heritage of the United States. In the United States and around the world, marine protected areas (MPAs) are increasingly recognised as an important and promising management tool for mitigating or buffering some of these impacts. This book examines the use of MPAs as a way to restore and maintain healthy marine and Great Lakes environments by contributing to the overall protection of critical marine habitats and resources. This is an edited, excerpted and augmented edition of various government publications.
In Sustainable Ocean Resource Governance an international group of eminent authors offer perspectives on the legal interface between sustainable economic growth, effective marine resource management and urgent environmental protection of the sea by addressing three key issues: deep sea mining, marine energy generation, and seabed pipeline and cable systems. In light of the sectoral nature of current ocean governance and the existing patchwork of management arrangements for the oceans, this book gives insights in search for a coherent and consistent sustainability approach.
"This is a timely book... [It] should be mandatory reading..." -- Minnesota Star Tribune More severe storms and rising seas will inexorably push the American coastline inland with profound impact on communities, infrastructure, and natural systems. In A New Coast, Jeffrey Peterson draws a comprehensive picture of how storms and rising seas will change the coast. Peterson offers a clear-eyed assessment of how governments can work with the private sector and citizens to be better prepared for the coming coastal inundation. Drawing on four decades of experience at the Environmental Protection Agency and the United States Senate, Peterson presents the science behind predictions for coastal impacts. He explains how current policies fall short of what is needed to effectively prepare for these changes and how the Trump Administration has significantly weakened these efforts. While describing how and why the current policies exist, he builds a strong case for a bold, new approach, tackling difficult topics including: how to revise flood insurance and disaster assistance programs; when to step back from the coast rather than build protection structures; how to steer new development away from at-risk areas; and how to finance the transition to a new coast. Key challenges, including how to protect critical infrastructure, ecosystems, and disadvantaged populations, are examined. Ultimately, Peterson offers hope in the form of a framework of new national policies and programs to support local and state governments. He calls for engagement from the private sector and local and national leaders in a "campaign for a new coast." A New Coast is a compelling assessment of the dramatic changes that are coming to America's coast. Peterson offers insights and strategies for policymakers, planners, and business leaders preparing for the intensifying impacts of climate change along the coast.
