Environmental Pollution
The things all around us are said to be our environment. It is a combination of land, water, air with the world of living beings and vegetations. There has been a wonderful balance in the environment created by Nature all down the ages, and this sustains life on earth. But man is the mostintelligent creature has tried to exploit Nature for his benefit. He has applied the inventive skill to make use of the resources in his own way. It has distributed the ecological balance leading to pollution. Our desire for using natural resources forour so-called progress and prosperity have made us destroy our environment causing great harm to our lithosphere, atmosphere, hydrosphere and biosphere We will certainly be in trouble in future. So, we should protect our environment at any cost.

General Effects of Pollution:Each and every component of environment is influenced by pollution in a number of ways.The impact of pollution on some biotic and abiotic components may be discussed as below:
(i) Effect on Plants:Photo-chemical smog’s, sulphur-dioxide (obtained from copper and lead smelter) and hydrogen fluoride (obtained from fertiliser manufacturing and aluminum reduction) cause injury to the plants and thereby reduce their growth and vegetation.In some cases, even when pollution levels have been not high enough to produce noticeable injury, the retardation in growth rate may occur.
(ii) Effect on Animals:Air pollutants cause eye and respiratory irritation in animals as well as in human beings. Water pollutants can endanger aquatic life killing millions of fishes and other animals every year. Sewage, toxic chemicals and diseased animals can make waterunfit for use by farm animals.
(iii) Effect on Human Beings:Human beings are probably the most concerned about the direct and indirect effects of pollution. Sufficiently high levels of pollutants are toxic or even lethal to every human being, although there is a wide range of sensitivities among the human population.
(iv) Effect on materials:Pollutants can cause deterioration of materials and constructions. Air pollutants like SO2and H2S04gas can corrode metals and building materials increasing the frequency of repair and replacement. Water pollutants, like suspended particles or dissolved inorganic compounds can also adversely affect pumps, industrial equipment’s and bridges.
