If nature were in charge of creating an enduring human economy, she would surely apply the same principles she applies in natural systems. Her goal would be a global system of bioregional living economies that secure a healthy, happy, productive life for every person on the planet in symbiotic balance with the non-human systems on which we humans depend for breathable air, drinkable water, fertile soils, timber, fish, grasslands, and climate stability. Each bioregional economy would meet its own needs for energy, water, nutrients, and mineral resources through sustained local capture, circular flow, utilization, and repurposing. Decision making would be local and the system would organize from the bottom up. Diversity and redundancy would support local adaptation and resilience.
