From the economical view point the Environmental Disruption (=ED) is regarded as one of the phenomena which show the lack of efficiency in the industrial activities of the modern society.
The present situation of the ED gives the very heavy load of social cost to the residents in the polluted areas. The real problem exists in the fact that industrial activities are responsible for the ED, while its victims are individual residents in the polluted areas and this fact is the very problem that we have to deal with in this thesis. It proves that the objective of private industrial activities does not function to maximize the social net product. This contradiction will be solved by establishing the rule to make those for its expense.
Certainly the Abatement cost will be increased by establishing this rule; however, the social cost will be cut down rapidly on the other hand. This relationship can also be applied to any industries that have a considerable responsibility for the ED from the view point of the national economic plan.
In short, as long as the private industrial activities keep operating without paying any consideration on environment security, it will cause the great loss in the national and/or international economical development.
