The Impact Of Marine Debris On Oceans The Environment Wildlife And Human Health

Plastics last for centuries in the natural environment and are found nearly everywhere on our planet. An estimated 8 million metric tons of plastic enter the oceans each year at a rate of about one garbage truck per minute, threatening biodiversity and accumulating in the seafood and in the water as discussed in chapter 1. Chapter 2 will examine the issues of man-made trash that is polluting the oceans, also known as marine debris. This marine debris can range from metals, glass, rubber, paper, textiles, and plastic.

This book describes how man-made litter, primarily plastic, has spread into the remotest parts of the oceans and covers all aspects of this pollution problem from the impacts on wildlife and human health to socio-economic and political issues. Marine litter is a prime threat to marine wildlife, habitats and food webs worldwide. The book illustrates how advanced technologies from deep-sea research, microbiology and mathematic modelling as well as classic beach litter counts by volunteers contributed to the broad awareness of marine litter as a problem of global significance. The authors summarise more than five decades of marine litter research, which receives growing attention after the recent discovery of great oceanic garbage patches and the ubiquity of microscopic plastic particles in marine organisms and habitats. In 16 chapters, authors from all over the world have created a universal view on the diverse field of marine litter pollution, the biological impacts, dedicated research activities, and the various national and international legislative efforts to combat this environmental problem. They recommend future research directions necessary for a comprehensive understanding of this environmental issue and the development of efficient management strategies. This book addresses scientists, and it provides a solid knowledge base for policy makers, NGOs, and the broader public.

Marine debris is a global pollution problem affecting marine life, maritime commerce and environmental quality. Scientists, policymakers and the public must be knowledgeable about the source, impact and control efforts if effective solutions are to be developed. Marine Debris addresses the origin of persistent solid waste in the ocean, from urban and rural discharges to waste from ships and the recreational use of oceans. The book identifies key issues from biological, technological, economic and legal perspectives, and gives a framework for controlling each of the main sources of marine debris.

This book discusses marine pathogens, pollution, and toxic algal blooms and their impact on coastal ecosystems and human health.

This book offers a detailed presentation of the principles and practice of life cycle impact assessment. As a volume of the LCA compendium, the book is structured according to the LCIA framework developed by the International Organisation for Standardisation (ISO)passing through the phases of definition or selection of impact categories, category indicators and characterisation models (Classification): calculation of category indicator results (Characterisation); calculating the magnitude of category indicator results relative to reference information (Normalisation); and converting indicator results of different impact categories by using numerical factors based on value-choices (Weighting). Chapter one offers a historical overview of the development of life cycle impact assessment and presents the boundary conditions and the general principles and constraints of characterisation modelling in LCA. The second chapter outlines the considerations underlying the selection of impact categories and the classification or assignment of inventory flows into these categories. Chapters three through thirteen exploreall the impact categories that are commonly included in LCIA, discussing the characteristics of each followed by a review of midpoint and endpoint characterisation methods, metrics, uncertainties and new developments, and a discussion of research needs. Chapter-length treatment is accorded to Climate Change; Stratospheric Ozone Depletion; Human Toxicity; Particulate Matter Formation; Photochemical Ozone Formation; Ecotoxicity; Acidification; Eutrophication; Land Use; Water Use; and Abiotic Resource Use. The final two chapters map out the optional LCIA steps of Normalisation and Weighting.

Marine litter is an ecological, economic, health and aesthetic problem. it is a complex and multi-dimensional challenge with significant implications For The marine and coastal environment, and human activities all over the world. The persistence of marine litter is the result of a lack of coordinated global and regional strategies, and deficiencies in the implementation and enforcement of existing programmes, regulations and standards at all levels - international, regional and national. The UNEP Global Initiative on Marine Litter provides a platform For The management of marine litter through the establishment of partnerships, cooperative arrangements and coordination of joint activities. it has succeeded in organizing and implementing regional activities on marine litter around the world. In addition to activities in 12 Regional Seas, UNEP commissioned preparation of several documents on specific topics, including UNEP/IOC Guidelines for monitoring of marine litter; Abandoned and lost fishing gear; and Marine litter and market-based instruments. This report provides an overview of the status of marine litter in UNEP's assisted Regional Seas, and highlights the amounts, main sources, impacts, and economics of marine litter, and discusses legislation, policies, compliance and enforcement mechanisms; institutional frameworks and stakeholder involvement; education and outreach strategies; monitoring programmes and research; mitigation activities among other aspects. it concludes that there is an urgent need to approach the issue of marine litter through better enforcement of laws and regulations, expanded outreach and educational campaigns And The employment of strong economic instruments and incentives. it proposes some general recommendations, based on the materials presented in the document, and specific recommendations for fourteen different issues regarding marine litter.

This report presents both short- and long-term approaches to the problem of marine plastic debris and micro plastics. It provides an overview of the latest science and experiences, identifies priority areas of action, and points out areas requiring more research. Improved waste management is urgently needed to reduce the flow of plastic into our oceans.
