In Chapter 2 we introduced a schematic describing the relationship between the​ natural and the economic systems. One side depicted (tasvirlamoq) the flow of mass and energy to​
the economic system, while the other depicted the flow of waste products back to the​ environment. In the last few chapters we dealt extensively with achieving a balanced​
set of mass and energy flows; now we examine how a balance can be achieved in the​ reverse flow of waste products back to the environment. Because the waste flows are​
inexorably intertwined with the flow of mass and energy into the economy, establishing a balance for waste flows will have feedback effects on the input flows as well.
