All our surroundings including air, water, soil, trees, animals make up our environment. Three factors determine the severity of a pollutant: its chemical nature, the concentration, and persistence. When the normal relations among these elements of nature are disturbed, the ecological balance is hampered and it is called environmental pollution. It is a sorrowful matter that the main elements of the environment which are essential for all living beings are being polluted in many ways. The major kinds of pollution, usually classified by the environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution. The smoke from factories and motor vehicles contain harmful substances like carbon-monoxide and sulfur-dioxide. These have hampered the cleanliness of the air. Mills and factories set up by river-banks let out chemical wastes in the river water. These poisonous substances are destroying the plants and creatures of the water bodies. Pesticides and chemical fertilizers used in agriculture are also polluting water. When people drink this water or take a bath in the polluted water, they are attacked with stomach and skin diseases. Pollution introduced by light at night is becoming a global problem, more severe in urban centers, but nonetheless contaminating also large territories, far away from towns. Environment pollution may be controlled by taking different measures, we may increase aforestation. If trees are planted in large numbers, we can be benefited in different ways. Trees also increase rainfall and prevent air pollution. Laws should be passed to prevent factories from dumping wastes into rivers. Moreover, every conscious individual and institution should come forward to solve this problem for the sake of our existence.
