The word Ozone originates from the Greek word "ozein" meaning ‘to smell'. Ozone is a toxic, gaseous, bluish molecule which has a strong odour and contains three Oxygen atoms with the formula O3. The ozone is situated in the in the part of the atmosphere called the Stratosphere about 12-35 km above the Earth's surface [1]. Ozone is formed when an oxygen molecule (O2) in the stratosphere is broken into two oxygen atoms (O + O) due to it absorbing UV rays emitted by the Sun; this oxygen atom (O) then reacts with another oxygen molecule (O2) to produce an ozone molecule (O3).

[1]

Ozone either protects or harms organisms on Earth depending on the height at which it is found. In the high Stratosphere "good" ozone acts like a shield protecting Earth's flora and fauna against the Sun's ultraviolet (UV) radiation. An excess of UV radiation increases the risk of contracting forms of skin cancers or ocular diseases. It may also weaken the natural immunity of human beings and......
