Most scientists agree that if pollution due to hazardous substances and other environmental deterrents continue at their present rate., the result will be irreversible damage to the ecological cycles and balances in nature upon which all life depends. Scientists warn that fundamental, and perhaps drastic, changes in human behaviour will be required to avert an ecological crisis.

          The problems facing the environment are vast and diverse. Global warming, the continuous depletion of the ozone layer, and incessant destruction of our rain forests are just some of the problems that many scientists believe will reach a critical proportions in the coming decades.

           All of these problems are directly affected by the size of the human population and the rapid global indutrialization that unfortunately, has brought about an impact and subsequent risks to health and the environment.
