| Abstract: | This study presents a model of two interactive pollutants in which the natural rate of regeneration of each pollutant is affected by the quantity of the other pollutant present in the atmosphere. The behavior of pollution accumulations in the natural unintervened system is characterized. With human intervention, it is shown that while a sustainable environment can be obtained, a deteriorating environment may also arise. There is a unique continuous boundary beyond which the environment is non-revitalizable. |
