air is everywhere. air has many components on earth. the components are very important for the balance of air on earth. air forms a blanket around the earth ,this blanket of air and gases is known as atmosphere. the percentile of air is as following: Nitrogen 78%
Oxygen 21%
Carbon-dioxide 0.03%
left over percent is other gases like argon, ozone, neon etc
oxygen is important for humans and animals to burn food present in their body. nitrogen is important for the plants as nitrogen is must in soil for fertile land to grow plants.carbon- dioxide is important for the respiration of plants and plants in return give oxygen for the respiration of humans. thus we can understand the importance of air.
pollution is caused by humans for our uses and selfishness. there are many types of pollution like air pollution, water pollution, land pollution, electronic pollution, medical pollution, nuclear pollution.
