Participatory deliberation, whereby diverse experts and publics collectively engage in decision‐making, can ensure a more informed and just decision by centering historically marginalized perspectives and engaging a spectrum of value systems. Broad and diverse participation is crucial for the equitable distribution of risks and benefits resulting from complex and uncertain decisions such as environmental gene editing. From an ethical position that gives intrinsic value to the nonhuman and recognizes the interconnectedness of species across generations, we argue that deliberation over environmental (...) gene editing must include the voice of nature and the voice of future generations. Inclusion of these key participant groups can encourage reflection on the human relationship with nature and help safeguard intergenerational equity of decisions reached. By drawing from the legal rights of nature movement, the Boardman River Dams Project, and methods for representative participation, we offer strategies for inclusion of nonhuman nature and future generations in deliberative processes about environmental gene editing and other crucial decisions about our shared environments.
