A number of influential biologists are currently pursuing efforts to restore previously extinct species. But for decades, philosophers of biology have regarded “de-extinction” as conceptually incoherent. Once a species is gone, it is gone forever. We argue that a range of metaphysical, biological, and ethical grounds for opposing de-extinction are at best inconclusive and that a pragmatic stance that allows for its possibility is more appealing.

This paper presents a way of classifying different forms of naturalness and unnaturalness. Three main forms of (un)naturalness are found as the following: history- based (un)naturalness, property-based (un)naturalness and relation-based (un)naturalness. Numerous subforms (and some subforms of the subforms) of each are presented. The subforms differ with respect to the entities that are found (un)natural, with respect to their all-inclusiveness, and whether (un)naturalness is seen as all-or-nothing affair, or a continuous gradient. This kind of conceptual analysis is needed, first, because (...) discussion concerning (un)naturalness is common in current bioethics and environmental ethics, and second, because the terms natural and unnatural are highly ambiguous. Thus, the lack of an exact definition of the type of (un)naturalness may lead into equivocation, other forms of bad argumentation, or at least vagueness. (shrink)

Artefacts are often regarded as being mere things that possess only instrumental value. In contrast, living entities (or some subset of them) are often regarded as possessing some form of intrinsic (or non-instrumental) value. Moreover, in some cases they are thought to possess such value precisely because they are natural (i.e., non-artefactual). However, living artefacts are certainly possible, and they may soon be actual. It is therefore necessary to consider whether such entities should be regarded as mere things (like most (...) non-living artefacts) or as possessing intrinsic value (like many, if not all) living entities. That is, it is necessary to determine whether artefactualness is a value-relevant property with respect to the intrinsic value of living things. (shrink)

Maintaining the coherence of the distinction between nature and artefact has long been central to environmental thinking. By building genomes from scratch out of 'bio-bricks', synthetic biology promises to create biotic artefacts markedly different from anything created thus far in biotechnology. These new biotic artefacts depart from a core principle of Darwinian natural selection – descent through modification – leaving them with no causal connection to historical evolutionary processes. This departure from the core principle of Darwinism presents a challenge to (...) the normative foundation of a number of leading positions in environmental ethics. As a result, environmental ethicists with a commitment to the normative significance of the historical evolutionary process may see synthetic biology as a moral 'line in the sand'. (shrink)

ABSTRACT Discourse analysis has been widely applied to the study of environmental communication, highlighting how language is used to reflect and affect our attitudes towards the natural world. The potential of discourse analysis to ‘reveal’ the values that people attribute to nature has recently been recognized in the context of environmental debates. This paper takes a new cross-disciplinary approach to the analysis of evaluation, combining a discourse approach and insights from environmental philosophy and environmental policy to address the following main (...) questions: Which values of nature may be embedded in discourse about nature? To what extent are these values represented in people’s narratives about trees and woodland in the U.K.? What are the implications of the findings for the critical analysis of evaluative discourse? What are the implications of the findings for environmental organizations? The analysis is applied to a sample of 514 woodland narratives collected by the U.K. charitable environmental organization Woodland Trust in 2016. The study highlights new critical perspectives that may be gained from the analysis of evaluative discourse and the importance of considering and fostering people’s affective relationship with the natural world in building a strong basis for environmental action.

Eric Katz in Zombie Arguments defends the thesis authenticity is indispensable to conservation. I agree. However, I argue authenticity appears in degrees and can be reclaimed by populations through their continuing evolutionary responses to the world. This means that interventions that diminish the value of a population through reducing their authenticity can be permitted in limited cases. When our actions retain the remaining authentic features in a threatened population we should allow such a diminishment as authenticity can be reclaimed in (...) time. (shrink)

In the 1920s and 1930s, an attempt was made to resurrect the aurochs (Bos primigenius primigenius), the extinct wild ancestor of contemporary domestic cattle. The back-bred species that was produced are called ‘Heck cattle’. I argue that the attempt to create the Heck cattle as a form of resurrected aurochs, and their subsequent use in rewilding projects (as in the Oostvaardersplassen in the Netherlands) is a prime example of the continuous human project of the domination of nature. The consideration of (...) domination as an extreme form of management serves as a critical lens on the policy of rewilding, similar to long-standing critiques of the policy of ecological restoration by this author. Rewilding projects do not re-create a ‘wild’ nature free from human intervention and activity. Rewilding is another form of the human management of natural processes to achieve anthropocentric goals. My examination of the Heck cattle in the rewilding process is intentionally provocative because there is a connection to Nazism. I will argue that policies of rewilding have historical antecedents (and parallels in philosophical meaning) to the Nazi plans for re-creating an authentic Aryan landscape in the lands of Eastern Europe. The case history of the Heck cattle projects illustrates the danger of pursuing radical forms of management of the natural world. (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.

This paper presents some of the most promising ways wild animals are currently being helped, as well as other ways of helping that may be implemented easily in the near future. They include measures to save animals affected by harmful weather events, wild animal vaccination programs, and projects aimed at reducing suffering among synanthropic animals. The paper then presents other ways of helping wild animals that, while noncontroversial, may reduce aggregate suffering at the ecosystem level. The paper argues that impracticability (...) and normative objections against reducing wild animal suffering fail against these ways of helping wild animals. (shrink)
