Guiding Principles
(pg 2 of 2)

The four "laws" of ecology that Barry Commoner articulated in 1971 still embody basic tenets for an intelligent operating context:

2. Everything must go somewhere.
3. Nature knows best.
4. There is no such thing as a free lunch.

With these thoughts in mind, let us explore How Rivers Run.

(Commoner, 1971)
