The pollution
Environmental pollution is defined as the unfavorable alteration of our surroundings. It is by product of man’s activities through direct or indirect efforts of changes. These changes could be in the physical, chemical and biological characteristics of land, air or water that harmfully affect human life or any desirable living thing. Human population explosion, rapid industrialization, deforestation, unplanned urbanization, scientific and technological advancement etc. are the major causes of environmental pollution. Nearly 35 percent of India’s total land area is subjected to serious environmental pollution. Three fourths of the earth consists of water, yet there is a scarcity of potable water. In India, all the sources of water like rivers, lakes, ponds and wells have been polluted and are unfit for drinking. As a result of the increased use of fertilizers, the rivers, seas and oceans have become contaminated with harmful pollutants. It is estimated that more than 500 tons of mercury enters the ocean every year. Oil slicks, pollution caused by the flow of industrial waste, sewage and fertilizer have also threatened the aquatic life.
