Environment pollution implies the contamination of the surroundings. Any abnormal change of environment in chemical, physical and biological characteristics in environment is called environment pollution. Environment is the whole system of our existence. Our environment is becoming polluted everyday for several reasons. Human beings mainly pollute environment. Massive industrialization is an important cause of environment. Smoke from motor vehicles also pollutes environment. Serious environment pollution occurs in big cities because buses, trucks and cars play in the streets everyday and emit smoke. Mills and factories also pollute water. They throw their waste products into rivers and canals. By burning wood and melting pitch for road construction people make more smoke and pollute air. We use pesticide in our crop fields. It also pollutes our environment. Indiscriminate cutting of trees has also turned unbalanced environment. The ecological balance is being lost as a result of environment pollution. If we all desire to live a healthy and tranquillized life, we should make our environment clean and free from pollution. We should be all whole-heartedly in keeping our environment fit for habitation.
