This important collection focuses on the nature and importance of biodiversity. The concept is clarified and its intrinsic and instrumental value are discussed. Even though the term biodiversity was invented in the 1980s to promote the cause of species conservation, discussions on biological diversity go back to Plato. There are many controversies surrounding biodiversity and a few of them are examined here: What is worthy of protection or restoration and what is the acceptable level of costs? Is it permissible to kill sentient animals to promote native populations? Can species be reintroduced if they have disappeared a long time ago? How should the responsibilities for biodiversity be shared? This book will be of interest to philosophers of science and biologists, but also to anyone interested in conservation and the environment.

This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasising the conservation of biodiversity. Sahota Sarkar criticises attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and prediction in traditional ecology and how individual-based models and Geographic Information Systems (GIS) technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyses the consensus framework for conservation planning through adaptive management. He concludes with a discussion of directions for theoretical research in conservation biology and environmental philosophy.

Biological diversity - or ‘biodiversity’ - is the degree of variation of life within an ecosystem. It is a relatively new topic of study but has grown enormously in recent years. Because of its interdisciplinary nature the very concept of biodiversity is the subject of debate amongst philosophers, biologists, geographers and environmentalists. The Routledge Handbook of Philosophy of Biodiversity is an outstanding reference source to the key topics and debates in this exciting subject. Comprising twenty-three chapters by a team of international contributors the Handbook is divided into six parts: Historical and sociological contexts, focusing on the emergence of the term and early attempts to measure biodiversity What is biodiversity? How should biodiversity be defined? How can biodiversity include entities at the edge of its boundaries, including microbial diversity and genetically engineered organisms? Why protect biodiversity? What can traditional environmental ethics contribute to biodiversity? Topics covered include anthropocentrism, intrinsic value, and ethical controversies surrounding the economics of biodiversity Measurement and methodology: including decision-theory and conservation, the use of indicators for biodiversity, and the changing use of genetics in biodiversity conservation Social contexts and global justice: including conservation and community conflicts and biodiversity and cultural values Biodiversity and other environmental values: How does biodiversity relate to other values like ecological restoration or ecological sustainability? Essential reading for students and researchers in philosophy, environmental science and environmental studies, and conservation management, it will also be extremely useful to those studying biodiversity in subjects such as biology and geography.

This book examines the role of ethics and philosophy in biodiversity conservation. The objective of this book is two-fold: on the one hand it offers a detailed and systematic account of central normative concepts often used, but rarely explicated nor justified, within conservation biology. Such concepts include ‘values’ (both intrinsic, instrumental, and, more recently, relational), ‘rights’, and ‘duties’. The second objective is to emphasize to environmental philosophers and applied ethicists the many interesting decision-making challenges of biodiversity conservation. The book argues that a nuanced account of instrumental values provides a powerful tool for reasoning about the values of biodiversity. It also scrutinizes relational values, the concept of rights of nature, and risk, and show how moral philosophy proves indispensable for these concepts. Consequently, it engages with recent suggestions on normative aspects of biodiversity conservation, and show the need for moral philosophy in biodiversity conservation. The overriding aim of this book is to provide conservation biologists and policy-makers with a systematic overview of concepts and assessments of the reasons for reaching prescriptive conclusions about biodiversity conservation. This will prove instrumental in clarifying the role of applied ethics and a refined understanding of the tools it can provide. This title will be of interest to students and scholars of conservation biology, conservation policy, environmental ethics and environmental philosophy.

Introduces the philosophical issues which ecology poses about the biological world and the environmental sciences attempting to protect it.

In the life sciences, there is wide-ranging debate about biodiversity. While nearly everyone is in favor of biodiversity and its conservation, methods for its assessment vary enormously. So what exactly is biodiversity? Most theoretical work on the subject assumes it has something to do with species richness—with the number of species in a particular region—but in reality, it is much more than that. Arguing that we cannot make rational decisions about what it is to be protected without knowing what biodiversity is, James Maclaurin and Kim Sterelny offer in What Is Biodiversity? a theoretical and conceptual exploration of the biological world and how diversity is valued. Here, Maclaurin and Sterelny explore not only the origins of the concept of biodiversity, but also how that concept has been shaped by ecology and more recently by conservation biology. They explain the different types of biodiversity important in evolutionary theory, developmental biology, ecology, morphology and taxonomy and conclude that biological heritage is rich in not just one biodiversity but many. Maclaurin and Sterelny also explore the case for the conservation of these biodiversities using option value theory, a tool borrowed from economics. An erudite, provocative, timely, and creative attempt to answer a fundamental question, What Is Biodiversity? will become a foundational text in the life sciences and studies thereof.

Biodiversity may refer to the diversity of genes, species or ecosystems in general. These varying concepts of biodiversity occasionally lead to conflicts among researchers and policy makers, as each of them require a customized type of protection strategy. This book addresses the questions surrounding the merits of conserving an existing situation, evolutionary development or the intentional substitution of one genome, species or ecosystem for another. Any practical steps towards the protection of biodiversity demand a definition of that which is to be protected and, in turn, the motivations for protecting biodiversity. Is biodiversity a necessary model which is also useful, or does it carry intrinsic value? Debates like this are particularly complex when interested parties address it from different conceptual and moral perspectives. Comprised of three parts, each complemented by a short introductory paragraph, this collection presents a variety of approaches to this challenge. The chapters cover the perspectives of environmental scientists with expertise in evolutionary, environmental biology, systematic zoology and botany, as well as those of researchers with expertise in philosophy, ethics, politics, law and economics. This combination facilitates a truly interdisciplinary debate by highlighting hitherto unacknowledged implications that inform current academic and political debates on biodiversity and its protection. The book should be of interest to students and researchers of environment studies, biodiversity, environmental philosophy, ethics and management.
