Answer: Environmental pollution refers to the pollution of natural conditions, land, air and water in which human beings, animals and plants live. There are various types of pollution in the environment. Air pollution, water pollution, sound pollution, arsenic pollution are some of them. Air is being polluted by the emission (wbM©Z nIqv) of harmful smoke. Mills and factories, vehicles with engines produce carbon dioxide, carbon monoxide and many other poisonous gases. By inhaling (wbk¦vm †bIqv) this polluted air, people suffer from various diseases. Water is polluted very easily. Human waste and industrial waste are greatly responsible for water pollution. Farmers use pesticides (KxUbvkK) and chemicals for producing crops. Floods and rain water wash these materials into ponds, rivers and other sources of water and by drinking this polluted water, people become sick. Again sound is polluted if it is above 70 decibel. Most of the vehicles use hydrolic horns which produce unbearable sound. Nowadays arsenic pollution is increasing alarmingly. If we don't take step to prevent these pollutions, our life on earth will be hellish (bviKxq). We should make everybody aware of the harmful effects of these pollutions. This is not all. Punishment should be given to those bad people who are directly involved with environmental pollution.
