Air is present everywhere around us. Our earth is suitable to live in for plants, animals and man as there is air. Air is an important component of the environment. We cannot see air with our naked eyes, but we can feel it. Moving air is called wind. It is refreshing when a cool breeze blows gently on a hot summer day. All animals and plants need air to survive. Because like the animals, the plants also respire. Inhaled air should be fresh. Polluted air is harmful for both animals and plants. Our bodies get badly affected when polluted air is inhaled. Plants can make polluted air fresh. Air becomes polluted because of different causes. We should be aware/concerned about the causes of air pollution.
