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)

Gene drives are potentially ontologically and morally disruptive technologies. The potential to shape evolutionary processes and to eradicate (e.g. malaria-transmitting or invasive) populations raises ontological questions about evolution, nature, and wilderness. The transformative promises and perils of gene drives also raise pressing ethical and political concerns. The aim of this article is to arrive at a better understanding of the gene drive debate by analysing how ontological and moral assumptions are coproduced in this debate. Combining philosophical analysis with a critical (...) reading of the gene drive literature and an ethnographic study of two leading research groups, the article explores the hypothesis that the development of and debate about gene drives are characterized by a particular intervention-oriented mode of coproduction. Based on the results of this exploration, we highlight the need for a broadening of the perspective on gene drives in which empirical, moral, and ontological concerns are addressed explicitly in their interplay rather than in (disciplinary) isolation from each other.

Gene drive technologies (GDTs) have been proposed as a potential new way to alleviate the burden of malaria, yet have also raised ethical questions. A central ethical question regarding GDTs relates to whether it is morally permissible to intentionally modify or eradicate mosquitoes in this way and how the inherent worth of humans and non-human organisms should be factored into determining this. Existing analyses of this matter have thus far generally relied on anthropocentric and zoocentric perspectives and rejected an individualist (...) biocentric outlook in which all living organisms are taken to matter morally for their own sake. In this paper, we reconsider the implications of taking a biocentric approach and highlight nuances that may not be evident at first glance. First, we shortly discuss biocentric perspectives in general, and then outline Paul Taylor’s biocentric theory of respect for nature. Second, we explore how conflicting claims towards different organisms should be prioritised from this perspective and subsequently apply this to the context of malaria control using GDTs. Our ethical analysis shows that this context invokes the principle of self-defence, which could override the pro tanto concerns that a biocentrist would have against modifying malaria mosquitoes in this way if certain conditions are met. At the same time, the case study of GDTs underlines the relevance of previously posed questions and criticism regarding the internal consistency of Taylor’s egalitarian biocentrism. (shrink)
