Importance Of Air Essay

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. Air plays a vital role in recycling one of Earth's most important substances: carbon. ... Animals and humans also release carbon dioxide into the air when they breathe. Through a process called photosynthesis, plants extract carbon dioxide from the air and use it to produce energy.

Carbon is important because you are a carbon-based life form and you need it to survive. Carbon sources include fossil fuel combustion, the decay of dead animals and volcanoes. Animals and humans also release carbon dioxide into the air when they breathe. Through a process called photosynthesis, plants extract carbon dioxide from the air and use it to produce energy. They also release oxygen during this process. When people and animals eat the plants, they ingest carbon and produce the energy they need to live. When they die, their bodies decompose, causing carbon to go back into the air as this endless cycle repeats itself. Lee,2017

The most obvious way humans use air is breathing it. Lungs take in oxygen from air and transfer it to the bloodstream for distribution to the rest of the body. Carbon dioxide is sent from the body back to the lungs where it is expelled from the body.

Air is vital to 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 Adenosine triphosphate (ATP). This biochemical generation of Adenosine triphosphate (ATP) is a basic requirement to sustain life on

So air which gets heated on earth surface rises up and cold air from sea surface moves on to the earth surface thus minimizing the rise in temperature. Earth’s atmosphere helps protect you from X-rays, cosmic rays and other particles that bombard the planet. Earth’s ozone layer helps reduce the amount of harmful ultraviolet radiation that reaches the surface. Air also reduces the possibility that meteorites and asteroids could level a city. Most space rocks vaporize in the air before they reach the ground, where they can cause destruction. Earth’s atmosphere also helps moderate temperatures so that its surface isn’t too hot or too cold to support life.
