However, the costs, p e r tonne, of managing the solid waste stream are by far the highest. T h e higher cost reflects the fact that, until recently, the extrusion of waste gases was completely ignored, being left to the agency of shifting air masses. Water t r e a t m e n t has b e e n a significant cost for over 150 years in most Western cities, but even then it was the custom to discharge sewage, either after primary treatment, or even n o treatment at all, to the nearest water body. However, nature has n o force equivalent to mobile air masses or gravity driven hydrology, to remove solid wastes.
