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)

Biological conservation practices and approaches take many forms. Conservation projects do not only differ in their aims and methods, but also concerning their conceptual and normative background assumptions and their underlying motivations and objectives. We draw on philosophical distinctions from the ethics of conservation to explain variances of different positions on conservation projects along six dimensions: (1) conservation ideals, (2) intervention intuitions, (3) the moral considerability of nonhuman beings, (4) environmental values, (5) views on nature and (6) human roles in (...) nature. The result is a map of the moral landscape of biological conservation, on which these six dimensions are layered. This map functions as a heuristic tool to understand conceptual and normative foundations of specific conservation projects, which we will illustrate with four paradigmatic examples: the Pisavaara Strict Nature Reserve, Predator Free New Zealand, the Oostvaardersplassen Nature Reserve and the Great Green Wall Project. With this map as a heuristic tool, we aim to conceptually illuminate disagreement and clarify misunderstandings between representatives of different environmental protection strategies and to show that the same project can be supported (or criticised) on different grounds.

This paper argues that the Lockean proviso can be utilized as a relevant principle of justice for food security under global climate change. Since reducing GHG emissions is key to enhancing food security, we suggest a global food security scheme that systematically allots, among all people, access to GHG sinks in food systems impacted by global climate change. For consideration of the scheme, it is important to have a principle of justice. Furthermore, it should incorporate the value of fairness. A (...) relevant principle of climate justice for food security should meet the following criteria: (1) the parties concerned under the scheme are states; (2) fairness does not undermine the requirement that the basic needs of all people must be met; (3) when determining fair burdens, a fair distribution of the rights to use GHG sinks should be sensitive both to each state’s responsibility for its GHG emissions and to (4) each state’s effort to reduce such emissions. With them in mind, first, we argue that the Lockean proviso can provide legitimate guidance for each state. Second, the Lockean proviso reasonably enjoins that a state has a right to a food system that secures its citizens’ basic needs, and a duty to meet the basic needs of other people. Third, the Lockean proviso can be deployed as a principle of both global justice and intergenerational justice for food security. Finally, the Lockean proviso enables us to count the reduction of GHG emissions by each state as “the fruits of its labors”. (shrink)

While in the humanities and social sciences at large we can observe posthumanist developments that engage with the microbiome, microbes are still not a major topic of discussion within environmental ethics. That the environmental ethics literature has not engaged extensively with this topic is surprising considering the range of theoretical challenges (and opportunities) it poses for environmental theorising. So, this paper is ‘looking through the microscope’ from an environmental ethics angle in order to see how these little beings challenge what (...) we consider to be ethically relevant and how we conduct moral theorising. Especially interesting is how a focus on microbes can simultaneously support and challenge individualist biocentric intuitions and theories, which attribute moral standing to (some) microbes. Accordingly, the main aim of this paper is to lay out crucial aspects of these challenges and present some initial arguments about why not all of them pose a serious threat to biocentric theorising—including biocentric theories of interspecies justice. The three challenges discussed are (1) the moral significance challenge, (2) the self-defence predicament, and (3) undermining individualist biocentric intuitions. (shrink)

Treves et al.’sarticleis an important contribution to an emerging interdisciplinary literature onwhat constitutes a viable and just response to the current biodiversity crisis. Mycommentary addresses three interrelated themes: (1) overcoming divisions, (2) hierarchies of moral worth and (3) ‘multispecies justice’inthe broader contextof justice.
