“Our essential connection with animals is ancient, and it runs deep. It extends from body to behavior, from psychology to society—forming the basis of our daily journey of survival. This calls for physicians and patients to think beyond the human bedside to barnyards, jungles, oceans, and skies. Because the fate of our world’s health doesn’t depend solely on how we humans fare. Rather it will be determined by how all the patients on the planet live, grow, get sick, and heal.”
