What Factors Cause Ozone Depletion?
CFC's i.e. Chlorofluro carbons and other harmful substances are responsible for the high rate of ozone depletion. The ozone layer prevents most harmful Ultra Violet (UV) rays from passing through the Earth's atmosphere. This has generated worldwide concern leading to banning the production of CFCs as well as any related ozone depleting chemicals such as carbon tetrachloride and trichloroethane.
What Consequences Does It Have On The Life On Earth?
Ozone depletion has many harmful effects on living beings. The direct exposure to the UV rays increases the risks of skin cancer, damage to plants, harm to flora and fauna in water bodies.
What Steps Are Being Taken At The World Forum?
The Montreal Protocol on substances depleting the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16th, 1987 and came into force on January 1, 1989. It is believed that if the international agreement retains, the ozone layer would recover by 2050. As the treaty was signed on 16th September, the United Nations General Assembly voted to designate this day as "The World Ozone Day", to commemorate the signing of the Montreal Protocol Treaty.
