"At places distant from where you are, but also uncomfortably close," writes David Takacs, "a holocaust is under way. People are slashing, hacking, bulldozing, burning, poisoning, and otherwise destroying huge swaths of life on Earth at a furious pace." And a cadre of ecologists and conservation biologists has responded, vigorously promoting a new definition of nature: biodiversity --advocating it in Congress and on the Tonight Show; whispering it into the ears of foreign leaders redefining the boundaries of science and (...) politics, ethics and religion, nature and our ideas of nature. These scientists have infused the environmental movement with new focus and direction, but by engaging in such activities, they jeopardize the societal trust that allows them to be public spokespersons for nature in the first place. The Idea of Biodiversity analyzes what biodiversity represents to the biologists who operate in broader society on its behalf, drawing on in-depth interviews with the scientists most active today in the mission to preserve biodiversity, including Peter Raven, Thomas Lovejoy, Jane Lubchenco, and Paul Ehrlich. Takacs explores how and why these biologists shaped the concept of biodiversity and promoted it to society at large--examining their definitions of biodiversity their opinions about spirituality and its role in scientific work the notion of biodiversity as something of intrinsic value and their views on biophilia, E. O. Wilson's idea that humans are genetically predisposed to love nature. Takacs also looks at the work of twentieth-century forerunners of today's conservation biologists--Aldo Leopold, Charles S. Elton, Rachel Carson, David Ehrenfeld--and points out their contributions to the current debates. He takes readers to Costa Rica, where a group of scientists is using biodiversity to remake nature and society. And in an extended section, he profiles the thoughts and work of E. O. Wilson. "When I'm asked, 'should we save this species orthat species, or this place or that place?' the answer is always 'Yes!' with an exclamation point. Because it's obvious. And if you ask me to justify it, then I switch into a more cognitive consciousness and can start giving you reasons, economic reasons, aesthetic reasons. They're all dualistic, in a sense. But the feeling that underlies it is that 'yes!' And that 'yes!' comes out of the affirmation of being part of it all, being part of this whole evolutionary process. And agreeing with Arne Naess that each species, each entity, should be allowed to continue its evolution and to live out its destiny... just do its thing, as we say. Why not? And the 'why not?' is there's too many people."--Michael E. Soule, from an interview in The Idea of Biodiversity "An important contribution, a first distanced examination of a critical, modern topic by a scholarly, honest broker."--E. O. Wilson, Harvard University. (shrink)

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 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. (shrink)

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.

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.

Sahotra Sarkar’s Biodiversity and Environmental Philosophy is a welcome addition to the fields of environmental philosophy and the philosophy of science. First, his book has a rigorous and careful discussion of why we should preserve biodiversity. This is all the more important since much of environmental ethics has rested on normative claims which are unclear in meaning, appear unjustified at best and unjustifiable at worst, and are politically ineffective. Second, Sarkar is at home in the (...) science of conservation biology and offers important analyses of methodological issues in both ecology and conservation biology. Third, his book does not sustain what might be thought of as a “North American bias” but takes seriously environmental issues and perspectives from many different places like Australia and India. In this commentary, I raise worries and open questions that can be divided into four sections: (a) those concerning moral philosophy, (b) those concerning ecology and in particular whether we are in an extinction crisis, (c) how biodiversity is defined as a concept, and (d) what the aim and structure of conservation biology is. Ultimately, though my analysis is critical at some junctures, its purpose is to repay and hopefully improve on Sarkar’s rewarding analysis. Let me now turn from praise to criticism. (shrink)

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', '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. (shrink)

The concept of biodiversity has played a central role within conservation biology over the last thirty years. Precisely how it should be understood, however, is a matter of ongoing debate. In this paper we defend what we call a classic multidimensional conception of biodiversity. We begin by introducing two arguments for eliminating the concept of biodiversity from conservation biology, both of which have been put forward in a recent paper by Santana. The first argument is against the (...) concept’s scientific usefulness. The other is against its value as a target of conservation. We show that neither of these objections is successful against the classic multidimensional conception of biodiversity. Biodiversity thus understood is important from a scientific perspective, because it plays important explanatory roles within contemporary ecology. Moreover, although it does not encompass all valuable features of the natural world, this does not show that we should abandon it as a target of conservation. Instead, biodiversity should be conceived as one of many grounds of value associated with ecosystems. This is consistent with concluding that a central aim of conservationists should be to protect biodiversity. (shrink)

Biodiversity conservation as a practical discipline has been significantly transformed over the past twenty years. Given the extent to which humans influence not only biodiversity loss, but also geographical distribution, and ecological dynamics, there has been a shift in the study of conservation as a scientific discipline from a concern strictly with ecological and biological diversity measures to an interdisciplinary field, drawing upon the human sciences. We draw upon several case studies to argue for the importance of attention (...) to local stakeholders, culture, and community values, in conservation practice. (shrink)

This book explores the notion of endangerment which stands at the heart of a network of concepts, values and practices dealing with objects considered threatened by extinction, and with the procedures aimed at preserving them. It looks at some of the fundamental ways in which this process involves science, but also more than science: not only data and knowledge and institutions, but also affects and values. With a focus on endangerment sensibility, it encapsulates tensions between the normative and the utilitarian, (...) the natural and the cultural. (shrink)

One potentially extremely fruitful use of the tools of corpus analysis in the philosophy of science is to help us understand disputed terrains within the sciences that we study. For philosophers of biology, for instance, few controversies are as heated as those over the concepts we use in taxonomy to classify the living world, with the definition of ‘species’ perhaps most fundamental among them. As many understandings of biodiversity, in turn, involve counting the number of species present in (...) a given area, these taxonomic concepts thus become crucially implicated in our efforts in conservation biology and our response to climate change. In this chapter, we present a corpus of taxonomic journal papers, and illustrate how it might be used to make progress in the history and philosophy of taxonomy. What parts of the biological world do taxonomists most often study? Are these areas of focus related to other methodological commitments, or perhaps to their underlying conceptual disagreement? Are species that are more important to conservation, or economic concerns, or more important to local cultures, more or less likely to be the target of biological study? Corpus-based methods, we argue, are uniquely powerful for approaching questions such as these, and we hope that the case we present can serve as a fruitful example for others considering their implementation.

This paper analyzes the concept of biodiversity in conservation biology and assesses potential methods for its measurement.

Biodiversity is a key concept in the biological sciences. While it has its origin in conservation biology, it has become useful across multiple biological disciplines as a means to describe biological variation. It remains, however, unclear what particular biological units the concept refers to. There are currently multiple accounts of which biological features constitute biodiversity and how these are to be measured. In this paper, I draw from the species concept debate to argue for a set of desiderata (...) for the concept of “biodiversity” that is both principled and coheres with the concept’s use. Given these desiderata, this concept should be understood as referring to difference quantified in terms of the phylogenetic structure of lineages, also known as the ‘tree of life’. (shrink)

After wondering why environmental aestheticians tend to undervalue biodiversity as an indicator of nature’s well-being, I discovered that Philosophy and Science are in a face off regarding biodiversity’s utility. For the most part, philosophers meet science’s confidence regarding biodiversity with skepticism. Rather than get bogged down in technical disagreements between scientists and philosophers over the possibility of measuring and utilizing biodiversity, this paper sidesteps that conflict by turning to the relationship between biodiversity and cultural (...) engagement. By describing: the link between spoken languages and species diversity, the significance of cultural differences, the role of cities and remote communities in encouraging and safeguarding biodiverse habitats, and the heterogeneous nature of difference itself when determining biodiversity; I effectively demonstrate how human beings who value their own culture protect nature, which reveals the most important reason to value biodiversity. Biodiversity may be impossible to track, extremely difficult to measure, and shares no correlation with stability, yet no other yardstick indicates cultural proliferation. This paper surveys three ways in which biodiversity can serve as a bio-indicator for human cultural engagement, just as lichens are bio-indicators for air pollution, ozone depletion, and metal contamination.

''Biodiversity'' is all to often used as a buzz-word, with no clearly defined meaning, let alone a strict procedure to measure it. This article proposes a logical procedure, based on a similar approach in socio-economics (to measure income inequality). Every element in our logical procedure is known. Bringing it all together as presented is new, as far as we know.

Advances in biotechnology mean that it may soon be possible to recreate previously extinct species. This has led to an emerging debate within bioethics about whether we ought to reintroduce extinct species into our ecosystems. In this paper, we discuss the role that biodiversity could play in this debate. Many believe that biodiversity is a good that should be protected. We argue that if biodiversity is a good, then this suggests it should also be promoted, including by (...) reintroducing previously extinct species. We begin by outlining different ways in which biodiversity could be conceptualized, and then analyze various accounts of its value. We suggest no approach justifies an asymmetry between “protecting” biodiversity by conserving species alive today, and “creating” biodiversity by introducing previously extinct species. This suggests that if we have reasons stemming from biodiversity to protect species from extinction, we will have similar reasons to reintroduce previously extinct species. We close by asking whether arguments from biodiversity speak in favor of introducing some novel species into the ecosystem. (shrink)

This paper critically discusses two areas of Sahotra Sarkar’s recent work in environmental philosophy : biodiversity and conservation biology and roles for decision theory in incorporating values explicitly in the environmental policy process. I argue that Sarkar’s emphasis on the practices of conservation biologists, and especially the role of social and cultural values in the choice of biodiversity constituents, restricts his conception of biodiversity to particular practical conservation contexts. I argue that life scientists have many reasons (...) to measure many types of diversity, and that biodiversity metrics could be value-free. I argue that Sarkar’s emphasis on the limitations of normative decision theory is in tension with his statement that decision theory can “put science and ethics together.” I also challenge his claim that multi-criteria decision tools lacking axiomatic foundations in preference and utility theory are “without a rational basis,” by presenting a case of a simple “outranking” multi-criteria decision rule that can violate a basic normative requirement of preferences and ask whether there may nevertheless be contexts in which such a procedure might assist decision makers.

For several decades now, biologists have been developing digital databanks, which are remarkable scientific instruments allowing scientists to accelerate the development of biological knowledge. From the beginnings of the Human Genome Project (HGP) onwards, genetic databanks have been a major component of current biological knowledge, and biodiversity databanks have also been developed in the wake of the HGP. The purpose of this paper is to identify the specific features of biodiversity data and databanks, and to point out their (...) contribution to biodiversity knowledge. (shrink)

Recent work in the philosophy of biology has attempted to clarify and defend the use of the biodiversity concept in conservation science. I argue against these views, and give reasons to think that the biodiversity concept is a poor fit for the role we want it to play in conservation biology on both empirical and conceptual grounds. Against pluralists, who hold that biodiversity consists of distinct but correlated properties of natural systems, I argue that the supposed (...) correlations between these properties are not tight enough to warrant treating and measuring them as a bundle. I additionally argue that deflationary theories of biodiversity don’t go far enough, since a large proportion of what we value in the environment falls outside bounds of what could reasonably be called “diversity”. I suggest that in current scientific practice biodiversity is generally an unnecessary placeholder for biological value of all sorts, and that we are better off eliminating it from conservation biology, or at least drastically reducing its role.

Estimating whether the Earth’s biota is in the middle of a crisis relies heavily on comparisons between present and past data about biodiversity or biodiversity surrogates. Although the past is a crucial source of information to assess the severity of the current biodiversity crisis, substantive conceptual and methodological questions remain about how paleodiversity and biodiversity are to be properly compared. I argue that to justify claims of a current biodiversity crisis is harder than it appears. (...) More precisely, I claim that paleodiversity measurements are incommensurable with contemporary measurements, given the different ways that biodiversity is conceptualized and operationalized. I conclude by proposing three possible ways of overcoming this incommensurability problem. (shrink)

Jonathan Newman, Gary Varner, and Stefan Linquist’s Defending Biodiversity: Environmental Science and Ethics is a critical examination of a panoply of arguments for conserving biodiversity. Their discussion is extremely impressive though I think one can push back on some of their criticisms. In this essay, I consider their criticisms of the argument for conserving biodiversity based on ecosystem services; specifically, ecosystem functioning. In the end, I try to clarify and defend this argument against their criticisms.

A recent article by Burch-Brown and Archer provides compelling arguments that biodiversity is either a natural kind or a pragmatically-valid scientific entity. I call into question three of these arguments. The first argument contends that biodiversity is a Homeostatic Property Cluster. I respond that there is no plausible homeostatic mechanism that would make biodiversity an HPC natural kind. The second argument proposes that biodiversity is a multiply-realizable functional kind. I respond that there is no shared function (...) to ground this account. The final, and strongest, argument, is that biodiversity is an ineliminable explanans and explanandum in various subdisciplines of biology. I argue that once we look at the details of the relevant research, not only does biodiversity in a broad sense not function in explanatory roles, but we must eliminate biodiversity in favor of more specific concepts in order to make sense of the leading explanations in contemporary ecology and conservation science.

While the precipitous decline of biodiversity threatens life-sustaining processes and vast segments of the human population, concern about its loss remains extremely shallow. Nearly all motivational campaigns falsely assume that upon appreciating the relevant information, people will be sufficiently motivated to do something. But rational argumentation is doomed to fail, for there exists a motivational gap between a comprehension of the crisis and action taken based upon such knowledge. The origin of the gap lies neither in the quantity and (...) quality of information on the crisis, nor in the putative conflict between self-interest and morality. Instead, it lies in “remoteness conditions” which dissociate decision-makers from ecological damage and enfeeble incentive to correct it. The central remoteness conditions are spatial, temporal, and consequential. They can be eliminated by concretizing and particularizing earth others. While direct-experience, place-based educational programs satisfy the criteria, they are uncommon. There is also little opportunity for working adultsto engage in these sorts of activities. As such, the outlook for endangered species and humans in the developing world remains dire. (shrink)

Among the instrumental value defenses for biodiversity conservation is the argument that biodiversity is necessary to support ecosystem functioning. Lower levels of biodiversity yield lower levels of ecosystem functioning and hence the inference that we should conserve biodiversity. In our book Defending Biodiversity: Environmental Science and Ethics, we point out three problems with this inference. (1) The empirical support for such an inference derives from experiments conducted on a very small set of ecosystem types (mainly (...) grasslands and fresh water aquatic) and ecosystem functions (mainly nutrient uptake, biomass production, and decomposition rates). These experiments suffer from a number of largely unavoidable logistical constraints making the generality of their results questionable. (2) Even if the experimental results were unequivocal, their lack of external validity would still raise significant questions about how (if at all) these results apply to real world conservation problems. And (3) even if the experimental results were unequivocal and completely applicable to conservation problems, relying on such defenses implies other rational policy commitments that are at odds with other positions that environmentalists commonly take. Odenbaugh and I disagree largely about what inferences follow from these points rather than about the points themselves. I think that what follows is that if environmentalists want to use instrumental value defenses, then we need to accept that not all biodiversity is useful to us, and parts that are useful are not necessarily more useful than alternatives that might threaten biodiversity. I also think that the unpalatable implied commitments need to be taken seriously. This may mean that we environmentalists have to accept that biodiversity should not always be conserved, and that parts of the environmentalist agenda are little more than strong personal preferences that others need not respect. If environmentalists are willing to accept these conclusions, then there are no problems with relying on these instrumental value defenses, but I suspect that environmentalists are likely to be unhappy with such conclusions.

In a world of massive extinctions where not all taxa can be saved, how ought biologists to decide their preservation priorities? When biologists make recommendations regarding conservation, should their analyses be based on scientific criteria, on public or lay criteria, on economic or some other criteria? As a first step in answering this question, we examine the issue of whether biologists ought to try to save the endangered Florida panther, a well known glamour taxon. To evaluate the merits of panther (...) preservation, we examine three important arguments of biologists who are skeptical about the desirability of panther preservation. These arguments are (1) that conservation dollars ought to be spent in more efficient ways than panther preservation; (2) that biologists and conservationists ought to work to preserve species before subspecies; and (3) that biologists and conservationists ought to work to save habitats before species or subspecies. We conclude that, although all three arguments are persuasive, none of them provides convincing grounds for foregoing panther preservation in favor of other, more scientifically significant conservation efforts. Our conclusion is based, in part, on the argument that biologists ought to employ ethical, as well as scientific, rationality in setting conservation priorities and that ethical rationality may provide persuasive grounds for preserving taxa that often are not viewed by biologists as of great importance.

The multifarious nature of biodiversity is considered in relation to difficulties of definite determination and managerial mandates for monitoring. At a micro scale there is some convergence with the concept of community, but the linkage is largely lost in the spectra of temporal scope, spatial scales, successional seres, and taxonomic trajectories. Practicality points to selecting suitable suites of indicators as surrogates for particular purposes. Domains of partial ordering on multiple indicators constitute comparable collectives, whereas different domains require recognition of (...) special situations. Theoretical treatise and practical process can proceed in parallel, with dialogue and cross-fertilization serving to invigorate and inspire; whereas compulsive concern for completeness and consistency can be counter-productive as well as unduly expensive. Inability to completely capture all aspects of biodiversity in one full formulation is interesting and integral to issues of biocomplexity. (shrink)

This paper examines philosophical debates about concepts of biodiversity, making the case for conceptual pluralism. Taking a pragmatist perspective, I argue that normative concepts of biodiversity and eco-centric concepts of biodiversity can serve different purposes. The former would help stress the values of local communities, which have often been neglected by both early scientific approaches to conservation, and by policy makers prioritizing the political or economic interests of specific groups. The latter would help build local research programs (...) independent of pressures from economic or political actors. I employ a case study on environmental research on walnut forests in Kyrgyzstan in support of my argument. Against tendencies to frame different understandings of biodiversity in terms of geographical areas, I propose an interpretation drawing on the philosophy of ecology. Adherence to environmental pragmatism enables a sufficiently complex picture of developing environmental research in the area, capturing issues about scientific framings and local understandings.

This article considers several of the most famous arguments for our being under a moral obligation to preserve species, and finds them all wanting. The most promising argument for preserving all varieties of species might seem to be an aesthetic one. Unfortunately, the suggestion that the moral basis for the preservation of species should be construed as similar to the moral basis for the preservation of a work of art seems to presume (what are now widely regarded as) erroneous conceptualizations (...) of "species". The article concludes by arguing that more promising approaches to how "species" ought to be conceptualized suggest that the preservation of species should be construed as of far greater aesthetic importance than is suggested by focusing upon the preservation of any single work of art. Hence, if we have a moral obligation to preserve a single artwork, then we have a far greater moral obligation to preserve species than has often been presumed. (shrink)

At the beginning of the twentieth century, the biologist Joseph Grinnell made a distinction between science and sentiment for producing fact-based generalizations on how to conserve biodiversity. We are inspired by Grinnellian science, which successfully produced a century-long impact on studying and conserving biodiversity that runs orthogonal to some familiar philosophical distinctions such as fact versus value, emotion versus reason and basic versus applied science. According to Grinnell, unlike sentiment-based generalizations, a fact-based generalization traces its diverse commitments and (...) thus becomes tractable for its audience. We argue that foregrounding tractability better explains Grinnell’s practice in the context of his time as well as in the context of current discourse among scientists over the political “biases” of biodiversity research and its problem of “reproducibility.”.
