A valuable and unique contribution both to environmental ethics and public policy analysis of the preservation of species question. Norton provides a critical overview of the range of thought on the issue, presents a new and comprehensive rationale for preservation of both species and ecosystems, and addresses policy issues. Originally published in 1988. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

For all persons seriously concerned about the destruction of natural environments in the contemporary world, this book presents a comprehensive rationale for preserving wild species and ecosystems. Bryan G. Norton appeals most centrally to "transformative value," the power of human contacts with wild species to transform and uplift the human spirit. Until now species preservationists have found a theoretical basis for their policies in the "demand" value of wild species for fulfilling certain narrowly defined human needs or in controversial and badly understood proposals about the "intrinsic" values of species. This work examines such rationales and diverges from them by pointing to new sources of value for wild species: they have worth because they can transform human values. Because of the central role of biological diversity in environmental concerns, the book also provides a fresh perspective on environmental ethics more generally. Why Preserve Natural Variety? is sponsored by the Center for Philosophy and Public Policy at the University of Maryland, as was The Preservation of Species: The Value of Biological Diversity, which was edited by Professor Norton.

Nearly 700 species of plants may become extinct by the year 2000. Faced with this overwhelming prospect, plant conservationists must take advantage of every technique available. This unique work summarizes our current knowledge of the genetics and population biology of rare plants, and integrates it with practical conservation recommendations. It features discussions on the distribution and significance of genetic variation, management and evaluation of rare plant germplasm, and conservation strategies for genetic diversity. Case studies focusing on specific problems offer important insights for today's challenges in rare plant conservation.

Presupposing no prior knowledge of philosophy, John Benson introduces the fundamentals of environmental ethics by asking whether a concern with human well-being is an adequate basis for environmental ethics. He encourages the reader to explore this question, considering techniques used to value the environment and critically examining 'light green' to 'deep green' environmentalism. Each chapter is linked to a reading from a key thinker such as J.S. Mill and E.O. Wilson. Key features include activities and exercises, enabling readers to monitor their progress throughout the book, chapter summaries and guides to further reading.

It is vital that we adopt interdisciplinary approaches such as ecological economics to gain an understanding of the values that determine human interaction with, and use and abuse of, the environment. This book is a model of applied ecological economics. It presents an accessible introduction to the subject while at the same time broadening its theoretical basis by introducing a post-positivist, participatory method. The theoretical framework is applied to case studies in biodiversity conservation, drawn from around the world and a range of different ecosystems. The book is a suitable textbook for students of ecological economics and an ideal introduction for scientists and environmentalists needing to understand the role of economics in ecology and conservation.

What is intrinsic value? What is the origin of value? Are people always superior to nature? This book is a philosophical analysis of the human relationship to the non-human world. It is a pioneering study of the philosophy of nature-conservation in relation to the discussion of intrinsic value. Vilkka develops a naturalistic or naturocentric theory of value that is based on ethical extensionism and pluralism. Vilkka analyzes natural values and environmental attitudes: zoocentrism, biocentrism, and ecocentrism. This book forms a taxonomy for nature having intrinsic value. The theory of intrinsic value is based on naturocentric and naturogenic values. The book questions the thesis of weak anthropocentrism that denies the existence of naturogenic values. In Vilkka's theory, animals and nature are the origin of value. She defends the existence of zoogenic and biogenic values in the non-human world and discusses the possibility of ecogenic value, nature as a whole having value independent of human or animal minds. Vilkka analyzes the goodness and rights of nature, the problem of priorities, and ecological humanism. A naturocentric recommendation is that the well-being of animals and nature should have priority over human values at least in some real decision contexts. Ecological humanism recommends an attitude of respect for people, animals, and nature. The book includes an extensive glossary, index, and bibliography.
