An Ecologist's Perspective on Health

"Birth Ecology" is a term I coined to describe my approach to pregnancy, birth, the postpartum period, and beyond. Ecology is the scientific study of how different parts of a system fit together, including all the living and non-living factors. When one part of a system is damaged or changed, essentially all other parts of the system respond, and an ecologist's job is to figure out how (for a video explaining ecology, click here.) What affects one part of the system affects all parts of the system. And it’s no different for pregnancy and birth.

The human body IS an ecosystem. First of all, we are affected by many non-living components of our environment such as light levels, nutrition, hydration, and chemical exposure. Second of all, we are not one body. We have TRILLIONS of bacteria and viruses living in and on our bodies, which are key players in our immune system, metabolismnutrition, and even mental health! Not only that, but our social interactions with other humans play critical roles in our emotional and physical vitality. The mind (brain) is a body part- an organ that controls all the other organs of the body. Contrary to popular western thought, there is no separation between mind and body! Our mental health IS our physical health, which is why our emotions make us either resistant or prone to disease. We can also consider the continuity between past and future in terms of development. Experiences in early childhood, even in utero, influence how our brain, nervous system, and endocrine system develops. These systems regulate our temperaments, emotions, and mental states, and so define our strengths and weaknesses into adulthood. Finally, the mother-fetus duo are a two-person biological system, a symbiotic pair. The mother's emotional state affects her baby's physical state. Her microbes affect her infant's health. And all of these affect pregnancy outcomes, labor outcomes, postpartum outcomes, and beyond.

The human body is an ecosystem if ever there was one. Yet medical practitioners do not receive any training in ecology, and so rarely have the skills to view human health from this perspective. Instead, they specialize in single systems and may not be fully informed about how the different systems of our body, inside and out, affect each other. I think an ecological perspective is an essential perspective to have when considering a human and her health, and I'm excited to share it with you!

One of my favorite ecology stories is about a grass and a rose in the alpine tundra of Colorado. I just couldn’t help myself, I had to include here it at the end of the blog. It demonstrates how nothing inside a system is isolated. If you like this innovative, holistic way of solving parenting challenges, go to “Contact Me” or “My Services” and we can chat more.

An Ecological Story, The Grass and The Rose: The grass and rose once equally dominated the Colorado alpine tundra. But nitrogen pollution from Denver and Boulder has been causing the grass to overtake the rose, and the entire tundra. But why?

All plants host symbiotic fungi that help them survive. The rose relies nearly exclusively on a single kind of fungus that helps it survive freeze, fights off competitor plants, and helps it access nutrients in these cold soils where nutrient release from decomposition is frustratingly slow. The grass, however, has a diverse fungal community. Each fungus contributes only a small amount to the grasses survival, so if one fungus disappears, there are plenty other to fill in behind it.

Nitrogen pollution kills the rose’s fungal friend, which not only leaves the rose weak and dying, but also has consequences for the entire tundra. The rose maintains the balance between all the tundra plants because it keeps the grass from overgrowing. When removed, balance is lost and the grass overtakes the rest of the plant life, causing many plant species to disappear. This affects food supply for local animals who rely on seeds, leaves, and other resources from the many plants that are meant to be there. Conversely, if the grass is removed, the rose continues to peacefully co-exists with the remaining alpine plants.

Using ecology we see the whole picture- how humans, the soil, the fungi, the rose, the grass, the other plants, and the animals fit together, how they affect each other, and how changes in one part of the system affect other parts of the system.
