"Cost of Everything" / "Ecosystem-Biosphere Metaphor"

I still want to develop my "cost of everything" economic theory in harmony with an "ecosystm/biosphere" metaphor. Hope you big brains want to help me. In short the basis is pretty basic: Think of each country as a biosphere that trades with other biospheres. First you have to understand people's priorities (e.g. on their own biosphere or all biospheres). Then get a systemic view of how many of a particular species (e.g. humans) you want to survive over time in that biosphere. Then you can solve for how many other items must exist in the biosphere to sustain that species. There's a lot more to it but I want to debate it verbally more before I write it all out.
