We’re Walking Ecosystems: Notes on Collaboration

Lately I’ve been thinking about collaboration. I envision a world where nations, geographic regions, cities, neighborhoods, and affinity groups find an ease and flow in working together.

Maybe it seems pie-in-the-sky, but we have a model for that kind of collaboration. It’s right here, as close as our own skin. Modern science now confirms that the human body is a collaboration in itself.

Some 90 percent of our cells are—get this—not human. They’re bacterial, or fungal, or even viral. Don’t be afraid! They mean us no harm. We’re their habitat. A walking community. A microbiome.

If we keep balance within the community of our cells—I’m talking happy bacteria and fungi here—we generally enjoy good health, and recover from illness more quickly.

This Brainscape article explains it all so well—the ecosystems within us, each with their own unique microorganisms. These wee “microbiota” do all kinds of things for us in exchange for giving them a suitable environment to thrive. They help with digestion, brain activity, and immune function, just for starters.

Most curiously, our mitochondria—an organelle within cells that is responsible for converting digested food into energy—contains DNA that is…not human. “These organelles came from outside of us, down a separate evolutionary path.”

At the microscopic level, human life depends on a symbiotic relationship.

From the article:

“When Charles Darwin wrote On the Origin of Species, the dominant theory soon came to be survival of the fittest: a rat race for domination and survival. But both of these examples — mitochondria and our internal biota — point toward another means by which life thrives and evolves: symbiosis.”

I find that fascinating, and also telling.

Of course, zoom in tighter on the cells of our body—and what are they? Whirling clouds of particles. There’s nothing solid to us.

We’re made of space, basically. Our lives reliant on organisms we have always vilified or at the very least, ignored.

Knowing that, is it possible to see the human community in a different way?
