This essay explores ways to extend the concept of planetary health in the context of the major planetary evolutionary transition humans are embedded in. I argue that planetary health can be naturally extended to a fully planetary scale, including geo- bio- techno- and noo-spheres issues. I show the need and importance for ethics and governance to become global, and I give some examples of physiological and psychological health issues from a planetary perspective.
