In this chapter, we describe three areas within the broad field of ecogenomics or postgenomics: epigenetics, proteomics, and microbiomics. We argue that these fields challenge traditional bioethics in different ways. Since epigenetic, proteomic, and microbiomic data may contain phenotypical information, they may intensify discussions about consent, privacy, and return of results. But these fields also firmly position organisms, including human beings, as deeply entangled with their environments, as constituted by context, history, and experiences as much as genes. This yields (...) new insights into concepts of health and development. We discuss precision medicine as an example of a systemic approach to health. We argue that acknowledging the entanglement of organism and environment also means recognizing the importance of interdisciplinarity for bioethics and thinking together biomedical ethics and environmental ethics.
