Ozone is a type of chemical element within which 3 atoms of oxygen mix to make one molecule of gas. It unremarkably isn’t found within the lower atmosphere. It exists within the layer between twenty and fifty kilometers on top of the surface.

The presence of gas is of singular importance as a result of it filters out the incoming ultraviolet (UV) radiation and therefore acts as a screen against ultraviolent radiation which will increase the incidence of carcinoma, cataracts, and different diseases of eyes.

It conjointly affects the body psychoanalytic process, that will increase the vulnerability of infectious diseases.

Increased ultraviolet illumination will seriously have an effect on plant and fish production.

Ozone Depletion
Ozone depletion refers to the sporting out or reduction of the number of gas within the layer. it had been initial known in Nineteen Seventies because of the appearance of supersonic craft, that fly within the lower layer and emit atomic number 7 oxides.

Ozone Depleting Substances
Ozone depleting substances area unit those substances that expend the layer.

It is found that the most important explanation for gas depletions is that the greenhouse gas (Chlorofluorocarbons) gases.

CFCs area unit used for a good vary of applications as well as refrigerant, foaming agents, plastic producing, fireplace termination agents, solvents for state change food, cleaners for electronic elements fine agent, solvents, aerosol, propellants, and therefore the production of foamed plastics.

Other gas depleting substances controlled by metropolis Protocol (discussed in a very later chapter) area unit.

Carbon tetrachloride (CCl4), methyl group chloroform (CH3CCl3)

Hydrobromofluorocarbons (HBFCs)

Hydrochlorofluorocarbons (HCFCs)

Methyl bromide (CH3Br)

Bromochloromethane (CH2BrCl)

There area unit serious consequences of gas depletion. Following area unit a number of the numerous consequences of gas depletion.

Plants and animals vary in their tolerance of ultraviolet rays. The ultraviolet rays harm deoxyribonucleic acid (the order in each living being). Crops like soybean area unit the worst affected.

Animals and humans even have custom-made to UVB radiation. just in case of depletion of the layer, there’s danger of skin cancer – a kind of carcinoma. The unwellness is currently nearly epidemic within the us.
