Pollution
The meaning of word pollution means to make things dirty. Accordingly the pollution of natural resources causes imbalance in the ecosystem. Currently we have been fatally surrounded by the major issue of environmental pollution. Pollution is the addition of any foreign or poisonous substances into the environment at very fast rate than the environment natural accommodation. The main causes of this social devil are the industrialization, deforestation and urbanization, the by-products of which causes contamination to the natural resources used by the living things on the earth as a routine of normal life.
Air pollution, water pollution and soil pollution are the most dangerous forms of pollution causing direct heath disorders to the human beings. We have no safe water to drink, pure air to inhale and pollution free land to crop. This widely spreading pollution need to be taken under control for the healthy survival of life on the planet in future. Different types of pollutants which are disturbing our natural ecosystem are gases (NO, SO2, CO2, CO, NO2), halogens (iodine, chlorine, bromine), deposited matters (dust, smog, grit), agrochemicals (insecticide, pesticides, herbicides), noise, photochemical oxidants (photochemical smog, peroxyacetyl nitrate, ozone, nitrogen oxides), organic compounds from industries (acetic acid, benzene, ether), radioactive materials (radium, thorium), some solid wastes (ash, garbage), etc.
Pollution is the big side effect of the industrialized societies of the modern world where industrial development and green house effect have adversely affected the ecosystem. Life supporting systems are speedily getting converted into the life destroying system because of the industrialization. Human greediness and misuse of freeness of doing anything lead them towards serious degradation and mismanagement of resources.
Earth is considered as the only planet suitable for the life existence in the whole universe. It gives us everything like air, water, land, plants, and sky for the healthy survival of the life. We cannot live here in the absence of all the basic components of life. In any case if the serious pollution problems occur, it causes hazardous to the life. Increasing number of vehicles on the roads and increasing demands of the usage of the petrol and diesel increases the risk of air pollution as petrol and diesel spread heavy amount of poisonous gases in the environment such as carbon monoxide, sulphur-dioxide, hydrocarbons, and many more gases are polluting the air. Now-a-days, a major threat to the life is due to the development of nuclear sciences.
The polluted air we breathe goes to our whole body and affect all the systems especially respiratory functions. It becomes the reason of origin of many diseases like cancer, respiratory problems, lungs disorders, bronchitis, asthma and many more. The increasing competitions of the nuclear experiments all over the world are creating the big threat of atmospheric balance destruction as this process releases lots of harmful chemicals, poisonous gases, and dust into the air which falls back again to the earth through acid rains and harms the growth of crops and life. This acid rain causes various harmful diseases to the human fraternity worldwide. Water pollution is increasing because of the direct drainage of industrial liquid wastes into the water of ocean, lakes, rivers, ponds and other water bodies. This water is used by the farmers in growing crops which we eat and disturb our physiological functioning.
