The precautionary principle has its origins in debates about environmental policy, but is increasingly invoked in bioethical contexts. John Harris and Søren Holm argue that the principle should be rejected as incoherent, irrational, and representing a fundamental threat to scientific advance and technological progress. This article argues that while there are problems with standard formulations of the principle, Harris and Holm's rejection of all its forms is mistaken. In particular, they focus on strong versions of the principle and fail to (...) recognize that weaker forms, which may escape their criticisms, are both possible and advocated in the literature.

I begin with my impressions of a narrative of redemption that is caught up in the formation of new environmental, social, and political aspirations for the aftermath of the COVID-19 pandemic. I then reflect on, first, pre-pandemic scholarship on “biosecurity” and, second, taking up a variation of the syndemic approach to understanding the COVID-19 pandemic. I end by arguing that we should not expect to live with “new normals” for living in a post-COVID-19 world that leaves intact “old normals” that (...) have historically contributed to the rise of anthropogenic environmental harms and inegalitarian social arrangements in the world today.

Ecology is the study of the interactions of organisms and their environments. The methods of ecology fall roughly into three categories: descriptive surveys of patterns of species and resource distribution and abundance, theoretical modeling, and experimental manipulations. Ecological systems are “open” systems, and patterns and processes are products of a huge number of interacting forces. Ecology and the environmental sciences have made enormous advances since the mid-twentieth century in the understanding of ecological systems, as well as in the human impact (...) on the environment. Theory in ecology usually centers on the development of models. Environmental outcomes are uncertain and when making decisions under uncertainty, there are a variety of options available. One option is to carry out a cost benefit analysis based upon expected utilities and other is to adopt the precautionary principle. Uncertainty and under determination of theory by evidence is a fact of life in science. (shrink)
