Pollution pollutes our environment. It is injurious to health. There are various types of pollution. There are air pollution, land pollution, water pollution and sound pollution. The air is polluted by smoking from factories and gases given out by cars. The thoughtless cutting of trees also pollutes the air. As a result people suffer from several lung and heart diseases. People of the cities are the worst sufferers. The land is polluted by uncollected garbage, plastic packets and soap water. Water is polluted particularly by the untreated sewage and chemical wastes from factories and homes. As a result of this water pollution many aquatic animals and plants are killed. So people should be made aware of its danger. Sewage treatment plants must be set up along the courses of rivers. And dumping of garbage on the river banks should be banned. Sound is also polluted by the sounds of horns, loud speakers, micro phones etc. It affects heart patients and children. It disturbs the students at their studies. It deafens our sense of hearing. To tackle this types of problems we need to be alert and plant more trees.
