the human population on earth is expanding rapidly which goes hand in hand with the degradation of the environment at large measures. humanity's appetite for needs is disarranging the environment's natural equilibrium. production industries are venting smoke and discharging chemicals that are polluting water resources. the smoke that is emitted into the atmosphere holds detrimental gases such as carbon monoxide and sulphur dioxide. the high levels of pollution in the atmosphere form layers that are eventually absorbed into the atmosphere. organic compounds such as chlorofluorocarbons (cfc’s) have generated an unwanted opening in the ozone layer, which emits higher levels of ultraviolet radiation putting the globe at large threat.
