Like ecology, environmental science is multi- and interdisciplinary. The three major subdisciplines of environmental science are : Population, Resources, Environment. Of the above three major subdisciplines with environmental science, this book is more concerned with the third - the ecological effects of stressors, with particular reference to those associated with the activities of humans. A chapter deals with the use and abuse of biological resources and the emerging field of ecological economics. Some sections deal with environmental impact assessment; ecological monitoring; and the responsibilities of ecologists in environmental issues, environmental education, and the design of sustainable economic systems.

Ecology and Environment by R N Bhargava,V Rajaram,Keith Olson,Lynn Tiede Pdf
The alarming rise in greenhouse gas and pollution level which has resulted in serious environmental and ecological harm is the biggest concern today. It has not only made the lives of mankind miserable but also threatens their very existence. The survival of human beings on Earth depends on the availability of clean environment. The nature can be protected only when there is a good understanding of the ecology. For this, young people and the general public have to become aware of the underlying issues associated with maintaining a clean environment and protecting the nature. Ecology and Environment has delved in depth on the subject and brings a broad perspective of the various issues. Following the curriculum of University Grants Commission, the book covers different types of ecosystem on the earth. It deals with the effective and sustainable use of natural resources which includes water, forest, mineral resources in the ground and productive land. The book explains the population trends in the world and India, and how it is impacting the environment. The role of public participation in promoting environmental sustainability is explored too.
In Ecology without Nature, Timothy Morton argues that the chief stumbling block to environmental thinking is the image of nature itself. Ecological writers propose a new worldview, but their very zeal to preserve the natural world leads them away from the "nature" they revere. The problem is a symptom of the ecological catastrophe in which we are living. Morton sets out a seeming paradox: to have a properly ecological view, we must relinquish the idea of nature once and for all. Ecology without Nature investigates our ecological assumptions in a way that is provocative and deeply engaging. Ranging widely in eighteenth-century through contemporary philosophy, culture, and history, he explores the value of art in imagining environmental projects for the future. Morton develops a fresh vocabulary for reading "environmentality" in artistic form as well as content, and traces the contexts of ecological constructs through the history of capitalism. From John Clare to John Cage, from Kierkegaard to Kristeva, from The Lord of the Rings to electronic life forms, Ecology without Nature widens our view of ecological criticism, and deepens our understanding of ecology itself. Instead of trying to use an idea of nature to heal what society has damaged, Morton sets out a radical new form of ecological criticism: "dark ecology."

Ecology and Applied Environmental Science by Kimon Hadjibiros Pdf
Ecology and Applied Environmental Science addresses the impact of contemporary environmental problems by using the main principles of scientific ecology. It offers a brief yet comprehensive explanation of ecosystems based on energy, populations, and cycles of chemical elements. The book presents a variety of scientific ecological issues and uses these to examine a range of environmental problems while considering potential engineering, scientific, and managerial solutions. It takes an engineering approach and avoids excessive biological detail, while introducing ecology with a systemic approach. The book examines categories of organisms as well as the physical and chemical processes that affect them. It refers to the dynamics of populations and analysis of their major mutual influences, elaborates on the roles of primary production, limiting factors, energy flow, and circulation of chemical substances in the ecosystems, and presents the basic functions of aquatic ecosystems. The author considers important issues related to environmental degradation of forests, aquatic habitats, coastal zones, other natural landscapes, and urban areas, includes a survey of problems related to waste and toxic and radioactive substances, and presents the greenhouse effect and impacts from climate change. He discusses environmental management prospects and the potential for technological control of pollution from liquid, solid, and gaseous waste. He also highlights existing tools for environmental management, ecological and social aspects of biodiversity and landscape protection, and the contrast between development and environment in combination with ideas about sustainability.

Environmental Ecology: The Impacts of Pollution and Other Stresses on Ecosystem Structure and Function deals with environmental studies on the ecological impacts of anthropogenic stresses. The book discusses more particularly the ways that anthropogenic or natural influences affect the quality of the inorganic and biotic components of the biosphere, as well as the human environment. The text discusses the sources of air pollution, the different toxic elements (naturally occurring contamination or anthropogenic sources), and acidifying substances or "acid rain." The author also cites several studies that deal with the reclamation of acidified bodies of water. Another topic the author addresses is declining forest areas; he then cites several case studies of this occurrence, such as those by Fowells, 1965; Hepting, 1971; and Auclair, 1987. The text also investigates the ecological effects of oil pollution caused during the refining process and transportation. The author then examines the general response patterns to ecological stress. The text is intended for advanced students of environmental ecology and environmental science, as well as for ecologists, environmentalists, and urban planners and officials.
Critical Political Ecology brings political debate to the science of ecology. As political controversies multiply over the science underlying environmental debates, there is an increasing need to understand the relationship between environmental science and politics. In this timely and wide-ranging volume, Tim Forsyth uses an innovative approach to apply political analysis to ecology, and demonstrates how more politicised approaches to science can be used in environmental decision-making. Critical Political Ecology examines: *how social and political factors frame environmental science, and how science in turn shapes politics *how new thinking in philosophy and sociology of science can provide fresh insights into the biophysical causes and impacts of environmental problems *how policy and decision-makers can acknowledge the political influences on science and achieve more effective public participation and governance.
Earth's climate is changing, and by the end of the 21st century in Europe, average temperatures are likely to have risen by at least 2 °C, and more likely 4 °C with associated effects on patterns of precipitation and the frequency of extreme weather events. Attention among policy-makers is divided about how to minimise the change, how to mitigate its effects, how to maintain the natural resources on which societies depend and how to adapt human societies to the changes. Natural systems are still seen, through a long tradition of conservation management that is largely species-based, as amenable to adaptive management, and biodiversity, mostly perceived as the richness of plant and vertebrate communities, often forms a focus for planning. We argue that prediction of particular species changes will be possible only in a minority of cases but that prediction of trends in general structure and operation of four generic freshwater ecosystems (erosive rivers, depositional floodplain rivers, shallow lakes and deep lakes) in three broad zones of Europe (Mediterranean, Central and Arctic-Boreal) is practicable. Maintenance and rehabilitation of ecological structures and operations will inevitably and incidentally embrace restoration of appropriate levels of species biodiversity. Using expert judgement, based on an extensive literature, we have outlined, primarily for lay policy makers, the pristine features of these systems, their states under current human impacts, how these states are likely to alter with a warming of 2 °C to 4 °C and what might be done to mitigate this. We have avoided technical terms in the interests of communication, and although we have included full referencing as in academic papers, we have eliminated degrees of detail that could confuse broad policy-making.

Ecology Is Permanent Economy by George Alfred James Pdf
For decades, Sunderlal Bahuguna has been an environmental activist in his native India, well known for his efforts on behalf of the Himalayas and its people. In the 1970s, he was instrumental in the successful Chipko (or "hug") movement during which local people hugged trees to prevent logging for outside concerns. He was also a leader of the long opposition to the Tehri Dam. In both conflicts, the interests of outsiders threatened the interests of local people living relatively traditional lives. George Alfred James introduces Sunderlal Bahuguna's activism and philosophy in a work based on interviews with Bahuguna himself, his writings, and journalistic accounts. James writes that Bahuguna's work in the Indian independence movement and his admiration for the nonviolence of Gandhi has inspired a vision and mode of activism that deserves wider attention. It is a philosophy that does not try to win the conflict, but to win the opponent's heart.
From Environmental to Ecological Law by Kirsten Anker,Peter D. Burdon,Geoffrey Garver,Michelle Maloney,Carla Sbert Pdf
This book increases the visibility, clarity and understanding of ecological law. Ecological law is emerging as a field of law founded on systems thinking and the need to integrate ecological limits, such as planetary boundaries, into law. Presenting new thinking in the field, this book focuses on problem areas of contemporary law including environmental law, property law, trusts, legal theory and First Nations law and explains how ecological law provides solutions. Written by ecological law experts, it does this by 1) providing an overview of shortcomings of environmental law and other areas of contemporary law, 2) presenting specific examples of these shortcomings, 3) explaining what ecological law is and how it provides solutions to the shortcomings of contemporary law, and 4) showing how society can overcome some key challenges in the transition to ecological law. Drawing on a diverse range of case study examples including Indigenous law, ecological restoration and mining, this volume will be of great interest to students, scholars and policymakers of environmental and ecological law and governance, political science, environmental ethics and ecological and degrowth economics.

Canadian Countercultures and the Environment by Colin MacMillan Coates Pdf
"In Canadian historiography, there has been an increasing attention on the 1960s. Studies have focused mainly on the radical politics of the period but tended to downplay the extent to which much of the intellectual and social ferment continued into the 1970s and 1980s. This present collection, Canadian Countercultures and the Environment, makes an important contribution to a number of fields. As most of the papers deal with the 1970s and 1980s, they will add to our knowledge of this understudied period. Furthermore, the phenomenon of the counterculture has been the subject of very little academic focus to date. Most importantly, this collection will contribute a sustained analysis of the beginning of key environment debates in the 1970s and 1980s. Papers examine a range of issues related to broad environmental concerns, topics which emerged as key concerns in the context of Cold War military investments and experiments, the oil crisis of the 1970s, debates over gendered roles, and the increasing attention to urban pollution and pesticide use. No other publication dealing with this time period covers the range of environmental topics (activism, midwifery, organic farming, recycling, urban cycling, and communal living) included in this collection. Geographically, this collection covers a range of case studies from the Yukon to Atlantic Canada--it includes two urban examples, and, not surprisingly, places a good deal of emphasis on activities in British Columbia. From the most cursory glance at the history of those who moved "back-to-the-land, " it is clear that they engaged with environmental issues in ways that have had a long-term impact on Canadian society."--
Ecology and Ecosystem Conservation by Oswald J. Schmitz Pdf
Meeting today’s environmental challenges requires a new way of thinking about the intricate dependencies between humans and nature. Ecology and Ecosystem Conservation provides students and other readers with a basic understanding of the fundamental principles of ecological science and their applications, offering an essential overview of the way ecology can be used to devise strategies to conserve the health and functioning of ecosystems. The book begins by exploring the need for ecological science in understanding current environmental issues and briefly discussing what ecology is and isn’t. Subsequent chapters address critical issues in conservation and show how ecological science can be applied to them. The book explores questions such as: • What is the role of ecological science in decision making? • What factors govern the assembly of ecosystems and determine their response to various stressors? • How does Earth’s climate system function and determine the distribution of life on Earth? • What factors control the size of populations? • How does fragmentation of the landscape affect the persistence of species on the landscape? • How does biological diversity influence ecosystem processes? The book closes with a final chapter that addresses the need not only to understand ecological science, but to put that science into an ecosystem conservation ethics perspective.
