‘One Health’ is an integrated approach to optimising the health of humans, animals and ecosystems. It is supported and promoted by major bodies like the UN Environment Programme (UNEP), World Health Organization (WHO) and others.

Yet, many argue that One Health has evolved to focus heavily on human health, without paying enough attention to the vital connection it has with the environment and ecosystems, on which all life depends.

What is ‘One Health’, and what role does the sustainability of the environment and ecosystems play within it? How can we move One Health away from being so focused on humans and instead take a more balanced, truly interconnected approach that values all parts of the system—people, animals, and the environment? What real-world challenges stand in the way, and what could we do to overcome them?"
