Cellular systems, ecosystems, and civilizations are, at base, thermodynamic systems. ...The system uses energy, eventually releasing it as useless heat. ...there is one vital difference between natural systems and human systems: natural systems receive a fixed energy input that never varies. If we could set a strict limit on energy use, we could build a human system that is just as stable as an ecosystem.

What farmers should aim for is... higher margins using fewer inputs on less land, and a system that is sustainable.

To find our steady state and solve the sustainability puzzle, we need to abandon the relentless quest for dominance. We need to abandon our visions of progress as growth... Only progress in diversity, equality, and beauty can stand the test of time. We need to live within our limits.
