- Climate change, ecological degradation and global inequalities are symptoms of an eco-social polycrisis that threatens global health and health equity. This polycrisis is deeply rooted in Western value systems. These can be described as anthropocentric and individualistic and support the prevailing neoliberal economic model.

If Planetary Health and One Health stay grounded in Western value systems, an extensive conceptual engagement might be problematic for bioethics. Instead of turning to Western concepts of health, bioethics should engage deeply with Indigenous and non-Western ways of knowing and critically reflect on its own role in inadvertently maintaining the status quo.…
