Environmental Pollution and Global Issue (With special regard to air pollution)

Abstract

Environmental pollution is a serious problem of the present era, which is becoming more severe day by day. In fact, pollution is not the problem of any one country but a global problem, with which the entire world community is struggling. Increasing pollution has damaged the environment and made it unbalanced and its adverse effects are also being seen in many forms. The biggest threat due to pollution is to human health. The trends presented by the World Health Organization (WHO) show that in about half of the cities of the world, the amount of carbon monoxide has reached a level harmful from the health point of view, while lead has reached this dangerous level in one-third of the cities. All living beings depend on a balanced environment for their growth, development and wellorganized life. Generally, various components are present in the environment in a certain quantity and proportion and equilibrium is maintained between these various components. Under specific circumstances, the dominance of unwanted and harmful components increases in the environment. As a result, the environment becomes polluted and living beings have to suffer its adverse effects. We can also say it this way that when the purity of natural resources is affected in such a way that their life utility itself starts getting destroyed, then this process is called pollution. When any component of the environment such as air, water, land etc., mixes with any other unwanted substance and brings about a change in its physical, chemical and biological properties, then it is no longer usable or causes harm to health, then that effect and result is called pollution. The literal meaning of pollution is ‘to make dirty or unclean, to make impure’. The main cause of pollution is considered to be human activities. In the present research study, a detailed description of environmental pollution and global problem has been presented.
