Download or read book The Praeger Handbook on Contemporary Issues in Native America written by Bruce E. Johansen and published by Bloomsbury Publishing USA. This book was released on 2007-04-30 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most Americans know very little about Native America. For many, most of their knowledge comes from an amalgam of three sources—a barely remembered required history class in elementary school, Hollywood movies, and debates in the news media over casinos or sports mascots. This two-volume set deals with these issues as well as with more important topics of concern to the future of Native Americans, including their health, their environment, their cultural heritage, their rights, and their economic sustainability. This two-volume set is one of few guides to Native American revival in our time. It includes detailed descriptions of efforts throughout North America regarding recovery of languages, trust funds, economic base, legal infrastructure, and agricultural systems. The set also includes personal profiles of individuals who have sparked renewal, from Sheila Watt-Cloutier, a leader among the Inuit whose people deal with toxic chemicals and global warming, to Ernest Benedict and Ray Fadden, who brought pride to Mohawk children long before the idea was popular. Also included are descriptions of struggles over Indian mascots, establishment of multicultural urban centers, and ravages of uranium mining among the Navajo. The set ends with a detailed development of contemporary themes in Native humor as a coping mechanism. Delving occasionally into historical context, this set includes valuable background information on present-day controversies that are often neglected by the news media. For example, the current struggles to recover Native American trust funds and languages both emerged from a cradle-to-grave control system developed by the U.S. and Canadian governments. These efforts are part of a much broader Native American effort to recover from pervasive poverty and reassert Native American economic independence. Is gambling an answer to poverty, the new buffalo, as some Native Americans have called it? The largest Native American casino to date has been the Pequots' Foxwoods, near Ledyard, Connecticut. In other places, such as the New York Oneidas' lands in Upstate New York, gambling has provided an enriched upper class the means to hire police to force anti-gambling traditionalists from their homes. Among the Mohawks at Akwesasne, people have died over the issue. This two-volume set brings together all of these struggles with the attention to detail they have always deserved and rarely received.

Download or read book Heavy Metals in the Marine Environment written by Robert W. Furness and published by CRC Press. This book was released on 2018-01-18 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.
Download or read book Environmental Racism in the United States and Canada written by Bruce E. Johansen and published by Bloomsbury Publishing USA. This book was released on 2020-04-14 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Flint, Michigan, to Standing Rock, North Dakota, minorities have found themselves losing the battle for clean resources and a healthy environment. This book provides a modern history of such environmental injustices in the United States and Canada. From the 19th-century extermination of the buffalo in the American West to Alaska's Project Chariot (a Cold War initiative that planned to use atomic bombs to blast out a harbor on Eskimo land) to the struggle for recovery and justice in Puerto Rico following Hurricane Maria in 2017, this book provides readers with an enhanced understanding of how poor and minority people are affected by natural and manmade environmental crises. Written for students as well as the general reader with an interest in social justice and environmental issues, this book traces the relationship between environmental discrimination, race, and class through a comprehensive case history of environmental injustices. Environmental Racism in the United States and Canada: Seeking Justice and Sustainability includes 50 such case studies that range from local to national to international crises.
Download or read book Anthropogenic Pollution of Aquatic Ecosystems written by Donat-P. Häder and published by Springer Nature. This book was released on 2021-09-30 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.
Download or read book Bioaccumulation in Marine Organisms written by J.M. Neff and published by Elsevier. This book was released on 2002-04-16 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large volumes of produced water are generated and discharged to the coastal and ocean waters worldwide from offshore oil and gas production facilities. There is concern that the chemicals in the produced water may harm marine ecosystems. This book summarizes the bioavailability and marine ecotoxicology of metal and organic contaminants that may occur in oil well produced water at concentrations significantly higher than those in ambient seawater. The contaminants of concern include arsenic, barium, cadmium, chromium, copper, lead, mercury, radium isotopes, zinc, monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, phenols, and bis(2-ethylhexyl)phthalate. The first part of the book is a detailed discussion of the chemical composition of produced water from offshore oil wells worldwide and its fates following discharge to the ocean. The remaining chapters of the book summarize the current scientific literature on the sources and distributions in the ocean of each of the contaminants of concern and their bioaccumulation and toxicity to marine organisms. This book will be of value to: environmental scientists in the oil and gas industry; marine toxicologists and ecological risk assessors in academia, government, and industry; government regulatory agencies concerned with marine environmental protection. The book advances the concept that bioavailability evaluation must be included in all ecological risk assessments and other environmental assessments of chemical contaminants in marine and freshwater ecosystems.

Download or read book A Little Less Arctic written by Steven H. Ferguson and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.
