RESUMO
Many of humanity's most serious problems are global, intergenerational, and ecological, yet current institutions are poorly placed to confront such problems. In part, this institutional challenge reflects difficulties with our basic concepts and theories. Bioethics is a central area where such questions arise. Although some have argued for an environmentalized bioethics since its inception, biomedicine has thus far failed to embrace the challenge, and some accuse most bioethicists of being "asleep at the wheel" (Schenck and Churchill 2021). This paper discusses the basic ethical challenge, offers the "perfect moral storm" analysis, and explores one promising new concept for bioethics, planetary health, in light of that analysis. Drawing on the foundational report of the Rockefeller Foundation-Lancet Commission (Whitmee et al. 2015) and using climate change as the example, the author argues that planetary health has significant strengths but also some weaknesses, and that identifying both is helpful in charting a path forward for environmentalized bioethics.
