Environmental pollution is a serious threat to the health and well- being of all living beings. Pollution means fouling of air, water and land by waste, smoke, chemicals etc. pollution is due to various reasons such as the growing such as the growing population, industries, use of fertilizers, the rise in the number of vehicles, etc. pollution is of three kinds- air pollution, water pollution, and land pollution.
This is the most dangerous kind of pollution and is very harmful not only to humans but all living things. It is generally due to the smoke given out by the factories, the fumes emitted by motor vehicles or the burning of fuels such as coal, petroleum. The radioactive particles discharged by nuclear weapons also pollute the atmosphere. All this causes great harm to mankind. Air pollution damages buildings and contaminates the atmosphere.
Water gets polluted by the chemical discharge from industries. For centuries, rivers, seas, and lakes have been used to dump the waste from industries. Human sewage is also dumped in rivers. Oil spilled into the sea from tankers also causes pollution. Contaminated water can pose serious threat to the health of living beings.
Land gets polluted by excessive use of chemicals, fertilizers and pesticides. Our household rubbish, such as rotten food, groceries, etc., also contributes to pollution of land and soil.
