Planetary Health has been defined as “the health of human civilisations and the natural systems on which they depend.” To fully appreciate this concept, we need to acknowledge the powerful impacts which humans are having on the environment around us. The changes we are forcing upon climate, land, water, and ecosystems are all having repercussions in a far greater way than anyone could have imagined at the turn of the 21st century. We are making survival increasingly difficult, not just for nature around us, but for us also.
