We’re big believers in the ripple effect here: the notion that everything we do has an impact on the world, and that small actions can have big results. Another big believer of this idea is Daphne Miller, an Integrative Nutrition visiting teacher, holistic physician, and expert on the relationship between farms and our health.

In this interview, Dr. Miller explains why our health relies on the decisions farmers make on their farms (hint: your immune system plays a big role), and why our own decisions matter more than we might think. “We are a part of the ecosystem,” she says, “and so every choice that we make is going to be part of that larger feedback loop.”

After spending a career exploring the intersection of environment and health, she has strong feelings about the importance of nature in our daily lives, going so far as to assert that public lands should be part of our healthcare system. Do you agree with Dr. Miller’s statement that “it’s not just that we’re connected to nature, we are nature”? And what does the closeness of this relationship mean in terms of cities’ responsibilities to maintain public land, or our neighbors’ decisions to use pesticides on their grass? We want to hear what you think. Watch the video and let us know your opinion in the comments below!
