One Health: Healing People by Healing the Planet

In recent years, scientists and policymakers have begun to recognize something our ancestors always knew: the health of people, animals, and the environment are inseparable. This understanding forms the foundation of the One Health approach — a movement that calls for doctors, ecologists, veterinarians, and public health experts to work together to protect life in all its forms.

At its core, One Health is simple: when ecosystems thrive, so do we. Restored forests filter air and water; biodiverse soils break down pollutants; microbes evolved in stable ecosystems help regulate disease and even inspire new medicines. Yet when we disrupt these systems — through deforestation, pollution, or overuse of antibiotics — we don’t just harm nature; we weaken our own defenses.

My research explores this intersection through a rewilding lens: asking whether regenerating ecosystems might harbor microbial communities with untapped medical potential. Could a rewilded forest or meadow — once degraded farmland — now nurture soil organisms that produce natural antibiotic compounds? This question embodies the One Health principle: by studying how nature heals itself, we may discover new ways to heal human disease.

But One Health goes beyond science. It’s also about leadership and collaboration. Restoring balance to our planet requires communities that bridge disciplines — where environmental scientists, physicians, and local leaders work side by side. In that spirit, my project brings together mentors from ecology, microbiology, and community health to show that innovation happens when we stop working in silos and start learning from the systems that sustain us.

As antibiotic resistance rises and ecosystems strain under human impact, the One Health approach reminds us that the most effective medicine may begin not in a lab — but in the soil beneath our feet.
