Today I Learned:

• Ozone layer is a layer of (relatively) high concentration of ozone (O3) located in the atmosphere

• Ozone layer absorbs most of UV light emitted from the sun, whose radiation is harmful towards biological cells

• Ozone layer is damaged by the use of chlorofluorocarbons (CFCs) which are used mainly as refrigerant

• Ozone layer located in the South Pole receive more damage during September to October due to increasing amount of chlorine radicals, which are released by UV radiation from chemicals which production is catalyzed by the Polar Stratospheric Cloud (PSC) during winter
