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)

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)

Recent advances in synthetic biology have made it possible to revive extinct species of animals, a process known as ‘de-extinction’. This paper examines two reasons for supporting de-extinction: the potential for de-extinct species to play useful roles in ecosystems; and human valuing of certain de-extinct species. I focus on the particular case of passenger pigeons to argue that the most critical challenge for de-extinction is that it entails significant suffering for sentient individual animals. I also provide reasons to take existence (...) value, or valuing the mere the fact that a species exists, into consideration in debates over de-extinction. (shrink)

Mimicry is common among animals, plants, and other kingdoms of life. Humans in late capitalism, however, have devised an unique method of mimicking the signs that trigger evolutionarily-programmed instincts of their own species in order to manipulate them. Marketing and advertising are the most pervasive and sophisticated forms of known human mimicry, deliberately hijacking our instincts in order to select on the basis of one dimension only: profit. But marketing and advertising also strangely undermine their form of mimicry, deceiving both (...) the intended targets and the signaler simultaneously. Human forms of mimicry have the regular consequence of deceiving the imitator, reducing meta-cognitive awareness of the act and intentions surrounding such deception. Therefore, the deceiver in the end deceives himself as well as intended targets. Drawing on scholarship applying Niko Tinbergen’s ethological discovery of supernormal stimuli in animals to humans, this article analyzes sophisticated mass mimicry in contemporary culture, in both intended and unintended forms.

Assisted migration, an ecosystem engineering technology, is receiving increasing attention and significant support as a means to save biodiversity in a changing climate. Few substantive, or not obviously deficient, reasons have been offered for why pursuing this conservation goal via these means might be good. Some proponents of AM, including those who identify themselves as “pragmatists,” even suggest there is little need for such argument. We survey the principal reasons offered for AM, as well as reasons offered for not offering (...) reasons. As exemplified by the case for translocating whitebark pine, which may at first seem especially strong, we note the incongruence of framing the goal of AM in terms of “saving biodiversity,” neglect of some crucial moral questions, marginalization of normative and scientific context when AM is cast as the lesser of two evils in a “crisis,” doubtful validity and, in any case, marginal importance of arguments that AM projects ought to be undertaken, inconsistent use of scientific facts, and omission of science that counters sanguine assessments. All told—even in cases such as whitebark pine for which AM may seem most defensible—there is little reason to think that AM projects are good as means to “save biodiversity,” or good as means to other goals that have accreted into arguments for these projects.
