Energy and ecology: why societies really succeed and fail

A human society that aspires for long-term sustainability will want to live in accord with basic ecological principles: energy comes from the sun; all resources are constantly cycled such that there is no waste whatsoever; fertile soil is the foundation of terrestrial life; and a sustainable population of a given species is one that is maintained at or within the carrying capacity of the ecosystem.
