I think it is about laws of thermodynamics. Go for the most concentrated
accumulation of energy, whether it is light, heat, nitrogen as in
manure, water from within a watershed....and recycle it through
successive systems of usage and successive cycles of reuse and
recycling, eliminating errors in the wastestream.
