Ozone present in the lower atmosphere is regarded as a pollutant and a greenhouse gas, that can contribute to global warming and climate change.

However, studies have pointed out that the lifespan of lower atmospheric ozone is quite less, compared to stratospheric ozone.

It is formed when oxygen molecules absorb ultraviolet photons, and undergo a chemical reaction known as photo dissociation or photolysis.

Ultraviolet radiations (UVR), are high energy electromagnetic waves emitted from the Sun.

UV radiation includes UV-A, the least dangerous form of UV radiation, UV-B, and UV-C, which is the most dangerous.

UV-C is unable to reach the Earth's surface due to stratospheric ozone's ability to absorb it.

The real threat comes from UV-B, which can enter the Earth's atmosphere, and has adverse effects.

Ozone layer depletion first captured the attention of the whole world in the latter half of 1970, and since then, a lot of research has been done to find its possible effects and causes.

At the same time, increase in the level of ozone in the lower atmosphere can enhance the ability of sunlight to synthesize vitamin D, which can be regarded as an important beneficial effect of ozone layer depletion.

Growing concern for ozone depletion led to the adoption of the Montreal Protocol in 1987, in order to reduce and control industrial emission of chlorofluorocarbons (CFCs).
