Learn about One Health
One Health is a collaborative, multisectoral, and transdisciplinary approach—working at the local, regional, national, and global levels—with the goal of achieving optimal health outcomes recognizing the interconnection between people, animals, plants, and their shared environment. The One Health approach is a holistic approach to advancing human well-being that recognizes that the health of people is closely connected to the health of animals and our shared environment: when we protect one, we protect all.
Why is One Health Important?
People, animals, and environments are interconnected so when you improve the health of one, you improve the health of the others. Humans interact with animals and plants through agriculture and food, outdoor recreation, and shared environments. Because people, animals, and plants share environments, they are all exposed to the same environmental factors.
One Health is a holistic approach that allows us to see the full picture and protect all pillars.
What is EPA's role in One Health?
EPA has long recognized the intricate, crucial, and interdependent links between people, animals, and their shared environments. Our researchers are working to develop ways to embrace the One Health approach as we work to safeguard the environment and protect public health. We are working with partners in the states, tribes, local communities, and public health organizations to use the One Health approach as a guide to meeting our shared missions.
