This book presents an argument that the environmental movement is a coalition of many groups working toward common objectives without common values. Norton believes this lack of unity causes unnecessary and divisive controversy and debate within the environmentalist community which impedes the development of effective and timely environmental management policies. The various participants in environmental debates see events so differently, and describe them in such diverse vocabularies, that the environmental movement, unlike other social action movements, lacks common theoretical principles. Norton's goal is to create a common language for discussing environmental issues as a first step towards a unified theory of environmental management. This book will be of a value to general readers with an interest in environmental and ecological issues; environmental planners and policy makers; conservation biologists, wildlife biologists; and ecologists.Norton, Bryan G. is the author of 'Toward Unity among Environmentalists', published 1994 under ISBN 9780195093971 and ISBN 0195093976.
