ABSTRACT
The purity of the air we breathe, the quality of the water we drink, and the beauty of the landscape around us are functions, to some degree, of the kind of control we exercise over the residuals generated by our production and consumption activities. That such residuals are an inevitable result of production and consumption activities has been explicated in a recent book by Kneese and others. 1 The "management" of such residuals is, therefore, a continuing process that will be with us so long as we live in towns and cities from which residuals are sufficient in quantity and quality to overwhelm the natural assimilative capacity of the ambient air, water, and land.
