The purpose of this paper is to propose a paradigm shift from "global nursing" toward "planetary nursing" to more effectively engage worldwide health initiatives, such as the United Nations 2030 Agenda for Sustainable Development. Such a shift expands the understanding of "health" from a phenomenon focused solely on humanity toward one of interdependent animal, environment, and overall planetary well-being, recalibrating the future roles and responsibilities of nursing accordingly. While there is limited data that discusses nursing-focused contributions to planetary health, the advancement of planetary nursing has been the focus of scholarly dialogue. Knowledge regarding the planet's systems, species, ecosystems, and myriad environmental dimensions must be integrated throughout nursing education to be translated to practice and social justice initiatives. As the profession deepens collaborations with international policymakers, nurses will become integral to advancing planetary health through social justice and health equity efforts.Nursing research must evolve to contribute to the goal of planetary health for the next generation and beyond. Ultimately, these authors call for a shift toward One Mind-One Health-One Planet to move the disciplinary stance from one of "global nursing" to a more expansive view of "planetary nursing" in alignment with initiatives to promote and sustain planetary health.

Nursing is well-positioned to make a paradigm shift from the procurement of human-and society-focused health and well-being toward the promotion of planetary resilience and sustainability. The Rockefeller Foundation-Lancet Commission on Planetary Health urges health care workers of the planet's dwindling capacity to sustain the growing human population, acknowledging planetary health "…is based on the understanding that human health and civilization depend on flourishing natural systems and the wise stewardship of those systems." 1(p1974) It is wellnoted that by integrating the planetary health agendas of our time into nursing curricula, 2 shifting our understanding of "health" from a humanbased phenomenon to one aligned with planetary thriving, 3 and promoting nursing-and midwifery-led research that is inclusive of planetary well-being, 4 the profession can fulfill its social contract with the communities it serves, from local to planetary. The purpose herein is to propose a paradigm shift from "global nursing," which has been used as a way to describe nursing's role in global health endeavors, toward "planetary nursing," which invites new and broader possibilities for nursing to engage worldwide health initiatives related to planetary health, such as the United Nations (UN) 2030 Agenda for Sustainable Development. 5 This concept of "planetar...
