In this article I explore, from a philosophical perspective, what the responsibility for biodiversity means. Biodiversity is a peculiar thing because it consists of the variety of life in its all manifestations, that is, in all its forms, levels and combinations. Variation is a main characteristic of life on earth. Because of its vastness a collective has not only a right but also a duty to take responsibility for biodiversity conservation, and furthermore it has a prima facie duty to implement (...) those measures the accomplishment of this requires. This includes the appropriate legislative and policy means. My argument for collective responsibility is mainly based on contrafactual reasoning, that is, if a collective takes no responsibility for the conservation of biodiversity, then no one takes responsibility. Providing that species extinction is something we definitely want to avoid, collective responsibility is well founded. (shrink)

In this paper, I present a sample spiritual exercise—a contemporary form of the written practice that ancient philosophers used to shape their characters. The exercise, which develops the ancient practice of the examination of conscience, is on the sixth mass extinction and seeks to understand why the extinction appears as a moral wrong. It concludes by finding a vice in the moral character of the author and the author’s society. From a methodological standpoint, the purpose of spiritual exercises (...) is to create a habit of thoughtfulness in the writer, and by way of teaching, to suggest one to the reader. Such a habit is important, at least, because virtue is a habit. In other words, there can be no learning of virtue itself without habituation into it. Accordingly, I frame the sample spiritual exercise with a deliberately controversial objection to contemporary academic virtue ethics and with a justification for why the spiritual exercise is important for taking virtue ethically. And I end the paper with some further remarks explaining the form of the exercise and its relevance to doing philosophy. In this way, the paper makes and illustrates a methodological point about virtue ethics based on a meta-ethical assumption about virtue as a habit, and it does this by focusing on a pressing environmental problem in the twenty-first century.

This paper contributes to biodiversity and species extinction literature by examining the relationship between corporate accountability in terms of species protection and factors affecting such accountability from forward-thinking companies. We use triangulation of theories, namely deep ecology, legitimacy, and we introduce a new perspective to the stakeholder theory that considers species as a ‘stakeholder’. Using Poisson pseudo-maximum likelihood regression, we examine a sample of 200 Fortune Global companies over 3 years. Our results indicate significant positive relations (...) between ecologically conscious companies that are accountable for the protection of biodiversity and species extinction and external assurance, environmental performance, partnerships with socially responsible organizations and awards for sustainable activities. Our empirical results appear to be robust in controlling for possible endogeneities. Our findings contribute to the discussion on the concern of species loss and habitat destruction in the context of corporate accountability, especially in responding to the sixth mass extinction event and COVID-19 crisis. Our results can also guide the policymakers and stakeholders of the financial market in better decision making. (shrink)

Each year, over 200 million people are infected with the malaria parasite, nearly half a million of whom succumb to the disease. Emerging genetic technologies could, in theory, eliminate the burden of malaria throughout the world by intentionally eradicating the mosquitoes that transmit the disease. In this paper, we offer an ethical examination of the intentional eradication of Anopheles gambiae, the main malaria vector of sub-Saharan Africa. In our evaluation, we focus on two main considerations: the benefit of alleviating the (...) malaria burden, and the loss of value that would accompany the eradication of the species. We outline a typology of the different ways in which species are valued or could be valuable, then use that typology to appraise the value of the species in question. We argue that Anopheles gambiae has minor (and redundant) instrumental value, little final subjective value and no objective final value. (shrink)

This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely ‘extinction of populations and species is bad’. Illustrating such debates in environmental ethics, the guiding question for this review concerns why – or when – anthropogenic extinctions are bad or wrong, which also includes the question of when that might not be (...) the case (i.e. which extinctions are even desirable). After providing an explanation of the disciplinary perspective taken (section “Introduction”), the concept of extinction and its history within that literature are introduced (section “Understanding extinction”). Then, in section “Why (or when) might anthropogenic extinctions be morally problematic?”, different reasons for why anthropogenic extinctions might be morally problematic are presented based on the loss of species’ value, harm to nonhuman individuals, the loss of valuable biological variety and duties to future generations. This section concludes by also considering cases where anthropogenic extinctions might be justified. Section “How to respond to extinctions?” then addresses a selection of topics concerning risks and de-extinction technologies. Finally, the section on “Extinction studies” introduces other viewpoints on the ethics of extinction from the extinction studies literature, followed by the “Conclusion”. (shrink)

Existence value refers to the value humans ascribe to the existence of something, regard­less of whether it is or will be of any particular use to them. This existence value based on preference satisfaction should be taken into account in evaluating activities that come with a risk of species extinction. There are two main objections. The first is that on the preference satisfaction interpretation, the concept lacks moral importance because satisfying people’s preferences may involve no good or well-being (...) for them. However, existence value can be based on a restricted version of the preference satisfaction theory, which is not vulnerable to the skeptical arguments about the link between preference satisfaction and well-being. The second objection is that even if preference satisfaction can be linked to well-being, understanding existence value in terms of individual preference satisfaction is incoherent, because existence value reflects disinterested preferences that involve no benefits to the individual. However, the fact that existence value may involve disinterested preferences does not threaten the coherence of the concept, but suggests that it does not fit smoothly into the “utilitarian” or “welfarist” framework it is commonly considered within. A pluralistic normative approach based on prima facie duties can be an alternative to standard utilitarian-style approaches for considering existence value in concrete cases involving a risk of species extinction, such as through deep sea mining.

This book is about the philosophy of de-extinction. -/- CHAPTER 1 introduces the two main philosophical questions that are raised by the prospect of extinct species being brought back from the dead—namely, the ‘Authenticity Question’ and the ‘Ethical Question’. It distinguishes the many different types and methods of de-extinction. Finally, it examines the aims of wildlife conservation with a view to whether they are compatible with de-extinction, or not. -/- CHAPTER 2 examines three prime candidates for (...) de-extinction—namely, the aurochs, the woolly mammoth, and the passenger pigeon. It is about what these animals were like, why people want to resurrect them, and the methods by which their resurrections could be accomplished. -/- CHAPTER 3 is about the authenticity of de-extinct animals. Critics of de-extinction have offered many reasons for thinking that the products of de-extinction will be inauthentic. The bulk of the chapter is taken up with surveying their arguments. We attempt to show that none are convincing, and end the chapter by offering and defending two arguments in favour of the view that authentic de-extinctions are possible. -/- CHAPTER 4 surveys and critically evaluates all the main arguments both for and against de-extinction. It presents a qualified defence of the claim that conservationists should embrace de-extinction. It ends with a list of do’s and don’ts for conservationist de-extinction projects. (shrink)

“De-extinction” projects propose to re-create or “resurrect” extinct species. Perhaps the most common justification offered for these projects is that humans have an obligation to make restitution to species we have eradicated. There are three versions of this argument for de-extinction—one individualistic, one concerned with species, and one that emphasizes ecological restoration—and all three fail to provide a compelling case for species revival. A general critique of de-extinction can be sketched that highlights how (...) it can both facilitate inattentiveness to biological and ecological boundaries and foster a managerial mentality toward the natural world.

This paper offers a paleobiological perspective on the debate concerning the possible use of biotechnology to bring back extinct species. One lesson from paleobiology is that extinction selectivity matters in addition to extinction rates and extinction magnitude. Combining some of Darwin’s insights about artificial selection with the theory of species selection that paleobiologists developed in the 1970s and 1980s provides a useful context for thinking about de-extinction. Using recent work on the prioritization of candidate (...) species for de-extinction as a test case, the paper argues that de-extinction would be a form of artificial species selection in which humans influence which species persist vs. go extinct. This points to a serious gap in our ethical theory: Much work has been done to clarify the value of biological diversity, but we also need theoretical guidance for decisions that amount to species sorting, and that will shape the macroevolutionary future.

Developments in genetic engineering may soon allow biologists to clone organisms from extinct species. The process, dubbed “de-extinction,” has been publicized as a means to bring extinct species back to life. For theorists and philosophers of biology, the process also suggests a thought experiment for the ongoing “species problem”: given a species concept, would a clone be classified in the extinct species? Previous analyses have answered this question in the context of specific de-extinction (...) technologies or particular species concepts. The thought experiment is given more comprehensive treatment here. Given the products of three de-extinction technologies, twenty-two species concepts are “tested” to see which are consistent with the idea that species may be resurrected. The ensuing discussion considers whether or not de-extinction is a conceptually coherent research program and, if so, whether or not its development may contribute to a resolution of the species problem. Ultimately, theorists must face a choice: they may revise their commitments to species concepts or they may recognize de-extinction as a means to make progress in the species problem. (shrink)

T. J. Kasperbauer presents an analysis of the ethics of de-extinction that is fairly distinctive in its focus on the welfare of individual animals. But while he is right to express concerns about individual animal well-being, individualism may not be the most important lens through which to view this issue. If one examines more closely what is at issue in de-extinction technologies in relation to species, additional problems appear that cast doubt both on the legitimacy of de- (...) class='Hi'>extinction projects, and on the limited defense of them that Kasperbauer offers.

Most current techniques to deal with invasive species are ineffective or have highly damaging side effects. To this end suppression-drives based on clustered regularly inter-spaced short palindromic repeats (CRISPR/Cas9) have been touted as a potential silver bullet for the problem, allowing for a highly focused, humane and cost-effective means of removing a target species from an environment. Suppression-drives come with serious risks, however, such that the precautionary principle seems to warrant us not deploying this technology. The focus of (...) this paper is on one such risk – the danger of a suppression-drive escaping containment and wiping out the target species globally. Here, I argue that in most cases this risk is significant enough to warrant not using a gene-drive. In some cases, however, we can bypass the precautionary principle by using an approach that hinges on what I term the ‘Worst-Case Clause’. This clause, in turn, provides us with a litmus test that can be fruitfully used to determine what species are viable targets for suppression-drives in the wild. Using this metric in concert with other considerations, I suggest that only three species are currently possible viable targets – the European rabbit, ship rat and Caribbean Tree Frog. (shrink)

This paper offers an account of the property Feuerbach and Marx called “species-being,” the human being’s distinctive tendency to identify herself as a member of her species, and to think of the species as a “we.” It links the notion to Kant’s theory of rights, arguing that every claim of right commits the maker of that claim to something like world government, and therefore to the conception of humanity as a collective agent. It also links species-being (...) to the concept of practical identity, arguing that the conceptions under which we find our lives and actions valuable are ones according to which we make a positive contribution to the life of the species. It then argues that the resulting conception of humanity, together with certain considerations about the nature of the good, provides grounds for challenging the familiar claim that death is generally worse for human beings than for animals. On the other hand, because of species-being, the extinction of our species is a much worse prospect for human beings than for the other animals. (shrink)

In this paper, we discuss the following four alternative ways of understanding the outcomes of resurrection biology. Implications of each of the ways are discussed with respect to concepts of species and extinction. Replication: animals created by resurrection biology do not belong to the original species but are copies of it. The view is compatible with finality of extinction as well as with certain biological and ecological species concepts. Re-creation: animals created are members of the (...) original species but, despite their existence, the species remains extinct. The view is incompatible with all species concepts presented. Non-extinction: animals produced belong to the original species which actually never went extinct. The view may be consistent with phenetic and phylogenetic species concepts as well as with finality of extinction. According to literal resurrection, resurrection biology is successful in reversing extinction through the creation of new members of species that once went extinct. This view presupposes non-finality of extinction and it is compatible with phenetic species concepts. It is notable that no species or extinction concept is consistent with all possible views of resurrection biology nor is any view of resurrection biology consistent with all species or extinction concepts. Thus, one’s views regarding species and extinction determine which views one can adopt regarding resurrection biology and vice versa. (shrink)

I have three aims in this paper. First, to consider the temporal way in which we conceptualise extinction. Second, to argue that our colloquial notion of time is in certain ways inadequate so far as said consideration goes. And third, in light of a different model of temporality better suited to thinking about extinction, to ask: what do we do now?

T.J. Kasperbauer argues that the most pressing problem for de-extinction is that it implies significant suffering for sentient animals. Though it is true that de-extinction entails suffering for se...

Beneath important ethical questions about the impacts of de-extinct species on ecosystems and the potential harms to individual organisms lies a more fundamental assumption; namely, that the thing being "de-extinct-ed" is indeed a member of previously existing species. This is the ontological assumption: that genetic make-up of the individual is both a necessary and sufficient condition for species membership. Questioning this ontological assumption poses an even more critical challenge for de-extinction. Genes a member of a (...) class='Hi'>species do not make. They represent a mere necessary condition. Sufficiency entails a broad set of ecological connections, inside and out. In this commentary on Kasperbauer’s target article, I argue for the primacy of ontology in the ethical analysis of de-extinction. (shrink)

The idea that the phenomenon of morality and, consequently, our ability to distinguish between vice and virtue can be explained by sympathy has been challenged as a highly controversial hypothesis, since sympathy appears to be easily influenced by proximity and selective, and would therefore seem incompatible with the possibility of taking an impartial, objective point of view. We intend to show that even a sentimentalist moral perspective such as the ‘Humean’ one, which places empathy (or ‘sympathy’, as Hume calls it) (...) at the core of morality, is capable of accounting for and justifying moral responsibility to future generations. Moreover, if we consider things from a Humean perspective, it is immoral not only to harm future generations, but also not to care at all about the extinction of the human species. For in the former case, we perform actions that cause misery, pain and suffering, whilst in the latter, we are not at all concerned about the welfare (i.e., happiness) of possible people who may, in the near future, come into the world and have a life worth or very much worth living. That is, in both cases, we show no ability to empathize with the possible people who will or may be born tomorrow. (shrink)

The title of Beth Shapiro’s ‘How to Clone a Mammoth’ contains an implicature: it suggests that it is indeed possible to clone a mammoth, to bring extinct species back from the dead. But in fact Shapiro both denies this is possible, and denies there would be good reason to do it even if it were possible. The de-extinct ‘mammoths’ she speaks of are merely ecological proxies for mammoths—elephants re-engineered for cold-tolerance by the addition to their genomes of a few (...) mammoth genes. Shapiro’s denial that genuine species de-extinction is possible is based on her assumption that resurrected organisms would need to be perfectly indistinguishable from the creatures that died out. In this article I use the example of an extinct New Zealand wattlebird, the huia, to argue—contra Shapiro—that there are compelling reasons to resurrect certain species if it can be done. I then argue—again, contra Shapiro—that synthetically created organisms needn’t be perfectly indistinguishable from their genetic forebears in order for species de-extinction to be successful.

Authors sometimes treat the promise of de-extinction as a forgone conclusion. But if we take Kasperbauer’s approach and assess the moral acceptability of de-extinction by weighting benefits to species against the suffering of individuals, the promise of de-extinction deserves greater critical attention. Accepting de-extinct individuals as replacements for extinct predecessors assumes species are separate from environment and can be reduced to DNA. In this response to Kasperbauer’s essay, I examine how the acceptability of de-extinction (...) might shift if we instead view species as the persistence of processes—the successful know-how of living in relation to other unfolding processes.

Scientific and public discourses on the current mass extinction event tend to focus their attention on the decline of ‘species’ and ‘biodiversity’. Drawing on insights from the humanities, this article contends that the processes of extinction also produce a diverse range of subjects. Each of these subjects, it argues, raises specific ethical challenges and creates opportunities for cosmopolitical transformation. To explore this argument, the article engages with several subjects of extinction: ‘species’ and ‘biodiversity’; ‘humanity’; ‘unloved’ (...) subjects; and absent or non-relational subjects. In each case, it examines how attention to these subjects can highlight the exclusions and inequalities embedded in dominant discourses, and to identify possibilities for plural ethico-political responses to mass extinction.

De-extinction technology aims to bring extinct species back into existence, often with the goal of releasing created organisms into natural environments. In this paper, I argue that there are aesthetic reasons to avoid engaging in de-extinction and release projects, even if they pass moral permissibility criteria. The strength of these reasons depends on conclusions regarding species authenticity - a problem that arises at the intersection of de-extinction technology and the 'species problem' in the philosophy (...) of biology. Since species authenticity affects the perceived naturalness of 'natural' environments, and thus the aesthetic judgments thereof, I contend that there will be negative aesthetic consequences of de-extinction efforts that ought to be further explored before such projects move forward.

A significant proportion of conservationists' work is directed towards efforts to save disappearing species. This relies upon the belief that species extinction is undesirable. When justifications are offered for this belief, they very often rest upon the assumption that extinction brought about by humans is different in kind from other forms of extinction. This paper examines this assumption and reveals that there is indeed good reason to suppose current anthropogenic extinctions to be different in kind (...) from extinctions brought about at other times or by other factors. Having considered – and rejected – quantity and rate of extinction as useful distinguishing factors, four alternative arguments are offered, each identifying a way in which anthropogenic extinction is significantly different from other forms of extinction, even mass extinction: (1) Humans are a different kind of natural cause from other causes of extinction; (2) Extinctions brought about by humans are uniquely persistent; (3) Anthropogenic extinctions are effectively random whereas past mass extinctions are rule-bound; (4) The impact of the current anthropogenic extinction event differs from the impact of other extinction events of the past, such that future recovery may not follow past patterns. Together, these four arguments suggest that the present-day extinction event brought about by humans may be unprecedented and that we cannot clearly extrapolate from past to present recovery from extinctions. Although insufficient as justification for the claim that present-day extinctions are undesirable, the arguments provide some ammunition for conservationists' conviction that species extinction – in which humans play an accelerating role – ought to be prevented.

Variation, adaptation, heredity and fitness, constraints and affordances, speciation, and extinction form the building blocks of the (Neo-)Darwinian research program, and several of these have been called “Darwinian principles.” Here, we suggest that caution should be taken in calling these principles Darwinian because of the important role played by reticulate evolutionary mechanisms and processes in also bringing about these phenomena. Reticulate mechanisms and processes include symbiosis, symbiogenesis, lateral gene transfer, infective heredity mediated by genetic and organismal mobility, and hybridization. (...) Because the “Darwinian principles” are brought about by both vertical and reticulate evolutionary mechanisms and processes, they should be understood as foundational for a more pluralistic theory of evolution, one that surpasses the classic scope of the Modern and the Neo-Darwinian Synthesis. Reticulate evolution moreover demonstrates that what conventional (Neo-)Darwinian theories treat as intra-species features of evolution frequently involve reticulate interactions between organisms from very different taxonomic categories. Variation, adaptation, heredity and fitness, constraints and affordances, speciation, and extinction therefore cannot be understood as “traits” or “properties” of genes, organisms, species, or ecosystems because the phenomena are irreducible to specific units and levels of an evolutionary hierarchy. Instead, these general principles of evolution need to be understood as common goods that come about through interactions between different units and levels of evolutionary hierarchies, and they are exherent rather than inherent properties of individuals.

This chapter commences with an account on the Zillo Beasts. The reawakening of extinct species, or "de‐extinction," has gained massive popular appeal. The chapter explains some facts before delving into the philosophical debate over de‐extinction. Philosophers sometimes use far‐fetched examples to answer the questions that are left after we agree on all the facts. These “thought experiments” are meant to show us what we really believe. What makes a duck a duck, a mammoth a mammoth, or a (...) Zillo Beast a Zillo Beast? This is called the species problem, and it is one of the oldest in the philosophy of biology. Essentialism is the view that permits us to say that the Zillo Beast's clone would be a member of the Zillo Beast species. The New Essentialists argue that essentialism can be compatible with natural selection if one looks beyond organisms' traits for species essences. (shrink)

Entrenched biases in favour of large, charismatic mammals, towards predators, towards terrestrial animals and towards species that have cultural importance can influence the selection of candidate species for de-extinction research. Often, the species with the highest existence value will also be the ones that raise the most serious animal welfare concerns.

“de-extinction” refers to the process of resurrecting extinct species by genetic methods. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. Although this recent “revival of the dead” raises deep ethical questions, the ethics of de-extinction has barely received philosophical treatment. Rather than seeking a verdict for or against de-extinction, this paper attempts an overview and some novel analyses of the main ethical considerations. Five dimensions of the ethics of de-extinction are (...) explored: (a) the possible contribution of de-extinction to promoting ecological values, (b) the deontological argument that we owe de-extinction to species we rendered extinct, (c) the question of “playing God” through de-extinction, (d) the utilitarian perspective, and (e) the role of aesthetic considerations in the ethics of de-extinction. A general feature arising from the paper’s discussion is that, due to de-extinction’s special character, it repeatedly tests the limits of our ethical notions. (shrink)

This article will explore a problem which is related to our moral obligations towards species. Although the re-creation of extinct animals has been discussed to some degree both in lay deliberations as well as by scientists, advocates tend to emphasize the technological and scientific value of such an endeavour, and the “coolness” factor, 32–33, 2013). This article will provide an argument in favour of re-creation based on normative considerations. The environmentalist community generally accepts that it is wrong to exterminate (...) species, for reasons beyond any instrumental value these species may have. It is often also claimed that humanity has a collective responsibility to either preserve or at least to not exterminate species. These two beliefs are here assumed to be correct. The argument presented here departs from and places these two ideas in a deontological framework, from which it is argued that when humanity causes the extinction of a species, this is a moral transgression, entailing a residual obligation. Such an obligation implies a positive duty to mitigate any harm caused by our moral failure. In light of recent scientific progress in the field of genetic engineering, it will be argued that humanity has a prima facie obligation to re-create species whose extinction mankind may have caused, also known as de-extinction.

Conservation biologists agree that humanity is on the verge of causing a mass extinction and that its primary driver is our immense and rapidly expanding global economy. We are replacing Earth’s ten million wild species with more of ourselves, our domesticated species, our economic support systems, and our trash. In the process, we are creating a duller, tamer, and more dangerous world. The moral case for reducing excessive human impacts on the biosphere is strong on both anthropocentric (...) and biocentric ethical grounds. The sine qua non for doing so is reducing human numbers and the size of our economies, while increasing the global acreage set aside in protected areas. We should take these steps as part of comprehensive efforts to create just and sustainable societies in which both humans and other species can flourish. (shrink)

In the life of any species, extinction is the final evolutionary process. It is a common one at present, as the world is entering a major extinction crisis. The pattern of extinction and threat is very non-random, with some taxa being more vulnerable than others. Explaining why some taxa are affected and some escape is a major goal of conservation biology. More ambitiously, a predictive model could, in principle, be built by integrating comparable studies of past (...) and present extinctions. We review progress towards both explanatory and predictive frameworks, comparing correlates of extinction in different groups at different times. Progress towards explanatory models for the current crisis is promising, at least in some well-studied taxa, but the development of a truly predictive model is hampered by the formidable difficulties of integrating studies of present and past extinctions.

Extinction is usually associated with the death of the last remaining individual of a species, taxon, or population of organisms. Here I ask the question of whether extinction might also be applied to cases where individuals of the relevant category remain alive. Global impacts in the Anthropocene suggest extinction may be broader than typically thought. Technologies available in the emerging ‘synthetic age’ alter taxa in ways that may appropriately be characterized as extinction. The core of (...) the more traditional account of extinction remains valuable. Losing the last few individuals of a taxon matters. But emerging types of loss may demand a broader understanding of extinction. This broader understanding could capture more of what humans are doing to the biosphere. (shrink)

The theme of human extinction is increasingly at the center of the current debate on moral philosophy and bioethics. We look at space missions and station construction projects capable of accommodating a large population and at the colonization of other planets with great hope. However, solutions are not excluded either, which for now certainly appear to be much more original. One of the most original projects involves launching a spacecraft containing cryopreserved human embryos, which, once they arrive at destination (...) on another planet, must be thawed and birthed by intelligent machines through artificial wombs (ectogenesis). In this paper, I do not intend to analyze whether the embryo space colonization project is indeed feasible. Instead, I will focus on examining the primary moral questions raised by the embryo space colonization project to determine whether, at least prima facie, it can be deemed morally acceptable. I will begin by discussing the objection advanced by Konrad Szocik (2021), according to which any embryo space colonization project is doomed to failure because it cannot offer the hoped-for solution to the problem of the extinction of the human species (second paragraph). In the third paragraph, then, I will ask whether embryo space colonization is able to ensure the people it brings into the world an adequate or at least the morally appropriate quality of life. Finally, in the fourth and last paragraph, I will examine the question of the morality of human reproduction that passes through the guidance and choice of intelligent machines. I will argue that to evaluate the morality of this project we should consider not only the interests and quality of life of the first people who could be born but also the interests of all possible subsequent generations.

In the midst of only the 6th mass extinction in the Earth's history, we must rethink how we teach evolution to prevent natural selection from being incorrectly used as a biological justification for inaction in the face of today's human‐caused mass extinction crisis. Pundits, policy makers, and the general public regularly identify the extinction of endangered species as natural selection at work, rather than attributing modern‐day extinction to the sudden catastrophic bad luck of human caused (...) environmental change, a phenomenon distinct from natural selection. In this natural selection framing, the inability of species to survive in human altered environments is the normal progression of “survival of the fittest” and conservation measures designed to protect species is human interference with natural selection. Paradoxically, this erroneous framing of extinction as the normal course of natural selection ignores humanity's exceptional role in causing today's mass extinction crisis. Our examination of this issue in U.S. college students indicates that it arises from misunderstanding the role of extinction in the history of life, leading us to recommend a greater teaching emphasis on the distinction between extinction and natural selection, and on past mass extinction events.

: Whether or not extinction caused by human activities is natural depends on which sense of the term 'natural' is under consideration. Given one sense of that term which has some grip on the popular imagination, it is. This suggests that at a minimum environmentalists should be very careful about invoking 'the natural' and related concepts such as 'acting naturally' when they propose moral principles. I argue here for the stronger claim that the 'natural' is either redundant and serves (...) to obscure more than it brings to light, or that it is bound up with a picture of the world which is false, and so theoretically useless. Thus 'the natural' can do no useful theoretical work in a completely developed environmental ethic. (shrink)

De-extinction raises anew ontological and epistemological problems that have engaged environmental philosophers for decades. This essay re-examines these issues to provide a fuller understanding—and a critique—of de-extinction. One of my claims is that de-extinction as a philosophical problem merely recycles old issues and debates in the field (hence, “zombie” arguments). De-extinction is a project that arises out of the assertion of human domination of the natural world. Thus the acceptance of de-extinction as an environmental policy (...) is an expression of a human-nature relationship that disvalues the natural world and subjugates nature completely to the interests of humanity.

Decades of globally coordinated work in conservation have failed to slow the loss of biodiversity. To do better—even if that means nothing more than failing less spectacularly—bolder thinking is necessary. One of the first possible conservation applications of synthetic biology to be debated is the use of genetic tools to resurrect once‐extinct species. Since the currency of conservation is biodiversity and the discipline of conservation biology was formed around the prevention of species extinctions, the prospect of reversing extinctions (...) might have been expected to generate unreserved enthusiasm. But it was not universal acclaim that greeted the coming‐out party for “de‐extinction” that was the TEDx conference and accompanying National Geographic feature in 2013. Why the concern, the skepticism, even the hostility among many conservationists about the idea of restoring lost species? And how does this professional concern relate to public perception and support for conservation? This essay explores the barriers to the acceptance of risky new genomic‐based conservation tools by considering five key areas and associated questions that could be addressed in relation to any new conservation tool. I illustrate these using the specific example of de‐extinction, and in doing so, I consider whether de‐extinction would necessarily be the best first point of engagement between conservation biology and synthetic biology.

Although episodes of captive breeding for display and acclimatization purposes date back to the 19th century, systematic breeding for species conservation first became the central mission for European zoological gardens in the interwar period. While most scholars explain this shift as a result of a decline in the global trade of exotic animals, my analysis points to the simultaneous renewed interest in native endangered and extinct species as a catalyst for captive breeding experiments. This article considers the role (...) of zoos in one of the earliest de-extinction projects, namely the breeding back of the Eurasian wild horse. By investigating two breeding programs, those initiated by Tadeusz Vetulani in Poland and the Heck brothers in Germany, my analysis reveals not only the political stakes, but also the different methods employed in these attempts to resurrect the tarpan. More specifically, I explore how scientific ideas about heredity and hybridization, as well as understandings of the porous boundary between domestic and wild horses, paved the way for selective breeding to be mobilized as a means of bringing back the extinct species. This ambitious goal reinvigorated the scientific function of the zoo by making it an experimental ground for undoing extinction, and laid the groundwork for its future role in the emergent wildlife conservation movement. In addition to mapping out knowledge exchange between zoologists, geneticists, and paleontologists, this article traces the circulation of specimens between natural history museums, zoos, and wildlife reserves to underscore the material dimension of ex situ conservation practices.

In the 1970s, the position that species are natural kinds characterized by essences came to be challenged, and was replaced by the view that species are individuals. To date, this remains the dominant position, at least among biologists, despite influential arguments that species can be construed as homeostatic property cluster kinds (employing a revised notion of essence). Recent philosophical discussions have broadened the scope by articulating a neo-Aristotelian essentialism for species, developing a post-essentialist account of human (...) nature, and scrutinizing temporal persistence conditions for species in the light of species de-extinction efforts. Yet most such current discussions concerning species have not relied on the notion of an essence, which also parallels recent accounts of natural kinds in the philosophy of science. (shrink)

The phenomenon of species extinction raises more and more concern among ecologists facing the actual crisis of biodiversity. Scientific investigations of the causes and effects of extinction must be completed by a philosophical analysis of the concept of extinction that aims to clarify the meanings of the term ‘extinction’ and to analyse modalities, criteria and degrees of extinction. We will focus our attention on the apparent paradox of the possible ‘resurrection’ of species in (...) the near future with the help of genetic biotechnology and cloning techniques. The ontological background of the extinction concept is analysed in relation to the idea of species as classes. We will also show that there is no simple analogy between death and species extinction, and develop a conceptualist and dualistic system of supra-individual entities , supported by an instrumentalist approach to genetic manipulations which transform species into interactive kinds, which can go extinct and be recreated.

The thylacine was a shy and elusive nonhuman animal who survived in small numbers on the island of Tasmania, Australia, when European settlers arrived in 1803. After a deliberate campaign of eradication, the species disappeared 130 years later. Visual and verbal constructions in the nineteenth century labeled the thylacine a ferocious predator, but photographs of individuals in British and American zoos that were used to illustrate early twentieth-century zoological works presented a very different impression of the animal. The publication (...) of these photographs, however, had little effect on the relentless progress of extermination. This essay focuses on the relationship between photographs of thylacines and the process of extinction, between images and words, and between pictures of dead animals and live ones. The procedures, claims, and limitations of photography are crucial to the messages generated by these images and to the role they played in the representation of the species. This essay explains why the medium of photography and pleas for preservation could not save the thylacine. (shrink)

Extinction deeply colors the way we think about conservation and the role of humans in nature. It is easy to overlook how recently, in fact, it has entered our consciousness. Only in the last two centuries has science sought to critically study life's origins, development, and diversification. Only in the last several generations have we identified and calibrated life's five major extinction events and speculated on their causes and effects. And only in recent decades have we come to (...) appreciate the still‐unfolding fate of life's diversity under the increasing influence of humanity. The story of extinction has continually changed as this monumental process of interdisciplinary synthesis and imagination has unfolded. Geology, paleontology, taxonomy, biogeography, and evolutionary biology have allowed us to comprehend the deep temporal and broad spatial dynamics of the extinction story. Archaeology, cultural anthropology, and environmental and economic history have illuminated the role of humans in altering the trajectory of species, landscapes, and ecosystems over the millennia. Ecology, genetics, population biology, and conservation biology have revealed the more recent patterns in life's vulnerability and resilience. As a phenomenon, extinction is as old as life itself. As a story shaping our consciousness, values, and intentions, it is still new. And it is uncomfortable. (shrink)

The paper explores the contact between the literary notion of the end of the world as depicted in H.G. Wells’s science fiction novel _The Time Machine_ and the concept of extinction, in the sense developed by the French naturalist Georges Cuvier, who at the turn of the 19 th century formulated a thesis about the structure of the world with a built-in end. The time traveller in Wells’s novel is driven into the distant future by an obsessive desire to (...) know the fate of the world. He encounters it on the shores of an already dead sea, where he is greeted by the image of a dying world, unmoving in the dull red light of a never-setting sun. Cuvier, on the other hand, encounters the end of the world as a reader of traces of history as told by nature through its layering and piling up. Within these layers, Cuvier recognises moments of repetitive interruptions that have left behind not only whole species and genera, but also entire worlds in the great natural history. The key question, then, is the status of the end within the proposed mechanism of return and repetition. (shrink)
