I have read many papers during my career, but the opening of one particular article astonished me: “Humans are ecosystems containing trillions of micro-organisms...” I read, wide-eyed.1 Back in 2018, the idea that I was interacting with ecosystems every time I treated a patient was revelatory to me. As I reflected on the importance of biodiversity to microbiome health, I was transported back to memories of time spent in the Amazon rainforest as a student. The scent of petrichor in the air, leafcutter ants creating beautiful patterns on the ground, the cacophony of monkeys and birds…The reverence and awe such memories evoked seemed a world away from the sterile clinic in which I read the paper.
As doctors, we have been trained to see and treat individuals in isolation from their environment. To prioritise industrial standards such as specialisation, efficiency, control. While we must acknowledge the huge advances such processes have enabled, we cannot escape that “human as machine” and “healthcare as factory” are implicit metaphors within industrialised healthcare. Were people machines, then a healthcare system designed to “fix” broken parts would make sense. But if we have inadvertently designed a system based on mechanistic thinking to support the health of complex, interacting ecosystems, we can begin to understand why healthcare—for all its successes—is so deeply unsustainable. After reading this paper I began musing: if people are ecosystems, should we design an ecological approach to health?
From practitioners of sustainable agriculture, I learned that an ecological approach to health can be elegantly simple. We can begin by creating conditions for health to flourish. While counter-cultural for a healthcare system that is reactive by design, this accords with a vast body of evidence. We know our lifestyles, income, education, employment, social relationships, and the built and natural environment together have far greater influence on our health outcomes than healthcare.23 Enabling active travel offers a simple example of how investment in the wider determinants of health may support health, not only at an individual level, but also for the population and the planet both now and in the future.4 At present we pour ever more resources into managing the health consequences of unhealthy environments. And yet we could equally start by cultivating common conditions for thriving and ensuring everyone can access them.
This is precisely what we are attempting in East Surrey, UK. Growing Health Together is enabling healthcare professionals within each Primary Care Network (PCN) of East Surrey Place, to collaborate as equal partners with citizens, schools, local government, the third sector, and other organisations, to improve local access to conditions for health and wellbeing.5 Just as every part of an ecosystem contributes to the health of the whole, we look to ensure that all those living or working in our area who wish to, may both benefit from and contribute to the creation of healthier places, especially those whose voices have been marginalised in the past. We wish to facilitate, in the words of the writer adrienne maree brown, “ideas that come from, and work for, more people.”6 While it is still early days for our project, this approach has already resulted in a diversity of initiatives across our PCNs, reflecting the unique interests, needs, and capabilities within each place. In Smallfield, for example, self-organised health champions are running a plethora of wellbeing groups, from yoga, to singing, and art. A new active travel infrastructure is being designed to support active lifestyles while reducing local air pollution. In nearby Horley, nature-based health initiatives are being developed by and for carers, young people with disabilities, and many more. This list barely scratches the surface of the health-creating activity underway.7 Our place-based model of prevention and health creation does not intend to replace high quality clinical care.8 But rather to support the long term viability of kind and careful healthcare, accessible to all, on a healthy planet.9
On a good day, I can already see the ecosystem of mutual care supporting the health of my patients and as a practitioner, I too, feel supported. On other days the barriers that still separate so many in our society from the sources of health come into sharp focus. It is undeniable that industrialised society is destroying much of irreplaceable value to current and future health, from the biodiversity of ecosystems within and outside our bodies, to the stability of our climate.101112 But for me, despair for such harms has been replaced by hope that, together, we may and indeed must, care for the abundance with which we are still entrusted.13 As health professionals, I believe we would do well to learn from my Indigenous hosts in the Amazon: stewards of some of the most sublime, biodiverse places on earth.
