Episode #455 from 21:39
Technosphere
Now I wonder if the technosphere also has a Gaian feedback or elements of a Gaian feedback? Such that the technosphere will also fight to some degree for homeostasis. Open question, I guess. Well, I'm glad you asked that question. Because that paper that David, and Sara, and I wrote, what we were arguing was is that over the history of a planet ... When life first forms, 3.8 billion years ago, it's thin on the ground. You've got the first species, these are all microbes. There are not enough of them to exert any kind of these Gaian feedbacks. We call that an immature biosphere. But then as time goes on, as life becomes more robust and it begins to exert these feedbacks keeping the planet in the place where it needs to be for life, we call that a mature biosphere. I'm sure later on, we're going to talk about definitions of life and such. There's this great term called autopoiesis that Francisco Varela, the Neurobiologist Francisco Varela came up with. He said, "One of the defining things about life is this property of autopoiesis," which means self-creating and self-maintaining. Life does not create the conditions which will destroy itself. It's always trying to keep itself in a place where it can stay alive. The biosphere, from this Gaian perspective, has been autopoietic for billions of years.
