Typically, we look at health in a human-only context. However, there is increasing recognition of the broader health concept that encompasses other species, our ecosystems and the integral ecological underpinnings of many drivers or protectors of health risks: At a planetary scale, ecosystems regulate the Earth system, making it and keeping liveable, while at the most intimate level, symbiotic microbial communities present in our gut and skin contribute to our nutrition, can help regulate our immune system, and prevent infections.
