With all the scientific discoveries, advanced technologies, and high-tech innovations, man oftentimes creates the very same instruments that curtail the life he treasures most. One culprit is pollution. History has recorded the details of its various effects to man, to other living creatures, and to the world. Pollution is the contamination of the environment by hazardous substances that can destroy the air man breathes, the water he drinks, and the land that provides his daily sustenance. Air pollution can be in the form of carbon monoxide which is emitted by smoke-belching vehicles, by pollutant factory wastes. It is also caused by open fires which give off chemicals and smoke by the burning of plastic wastes. Atmospheric nuclear test has also contributed its part in the pollution. Another potentially serious pollutant with its long term effects is carbon dioxide, large amount of which are discharged into the atmosphere by the burning of the fossil fuels. A continuous increase in the atmospheric carbon dioxide level is producing the so called ‘’green house’’ effect, which is increasing the average global temperature and may go on to cause catastrophic climatic changes. There are more to consider, such as the pesticides that destroys wild life and disturb the natural food chain; the use of spray nets, and other aerosols that contain chloroflorocarbons (CFCs) which is the very substance that...
