Ecosystems rely on cyclical material flows.  Industries can can too, but don’t always do so.  Can an entire economic system be circular?

A forest recycles carbon dioxide and soil nutrients (Nitrogen, phosphorous, potassium, etc…).  The amount of these materials available in air, soil, and water remains relatively stable (changes slowly) over time

The rapid combustion of fossil fuels has increased CO2 by more than 30% and more than doubled the amount of biologically available nitrogen, causing rapid changes in climate, habitat, and biodiveristy.

The vehicle that you are driving today will be a source of numerous recyclable materials tomorrow.  80-90% of a car’s solid mass is recycled.
