Importance Of Air In Human Life

Air consists of many gases like nitrogen, oxygen, inert gases in varying proportions. Besides it also has gases like hydrogen, carbon monoxide, carbon dioxide, sulfur dioxide, nitrous oxide etc. It is naturally clean and suitable for human and animal survival. But, due to industrialization there is rise in air pollution, which is not safe for breathe. So to avail clean air and keep up dust free breathing air condition and air filtration devices are used widely.

There are a number of importance of air as a basic requirement of human life. These include the following: supplying energy,conducting medium for sound, supporting water cycle, helping in pollination of crops maintainance of temparatute, power generation, production of rains,transportation, balancing the humidity, reduction of friction and creation of pressure.

Air is the essential supplier of energy: All living beings including plants & animals are dependent on air oxygen for generation of valuable life energy. Body cells take up oxygen from blood and generate energy from food in the form of ATP. This biochemical generation of ATP is a basic requirement to sustain life on earth. Air is a conducting medium for sound: We can hear sound of speech or cry or noise etc. only in the presence of air. This is because air is a good conductor of sound.
