While the increasing levels of Carbon Dioxide in the Atmosphere is responsible for global worming, the effects of Chlorofluorocarbons ( CFC) compounds commonly known as the Freons and Bromofluorocarbons commonly known as the Halons are as disastrous as the Carbon Dioxide. CFCs and other contributory substances are commonly referred to as Ozone-Depleting Substances or ODS. Because of the photodisassociation process the Atomic Chlorine & Bromine separated from Freons & Halons are constantly released in to the earth’s atmosphere. These Atomic Chlorine & Bromine through the catalytic process are responsible for the depletion of the Ozone layer in the Earth’s atmosphere.
Most of us know that one of the constituents of sun light is Ultra Violet Rays. It is believed that Ultra Violet rays have the tendency to create a variety of biological disorders such as increase in the Skin Canncer, damages Protiens & DNA, Plants and Vegetation , and reduction of Plankton populations in the photic zones of the ocean. Since the ozone layer prevents most harmful wavelengths (270–315 nm) of Ultraviolet Light from passing through the Earth's atmosphere, it is therefore very essential that the Ozone layer in the Earth’s stratosphere remains protected. There is a worldwide concern about this leading to a special resolution passed by heads of states at Montreal which is known as the Montreal Protocol, banning the production of CFCs and halons as well as related ozone depleting chemicals.
While there is great effort in minimising the usages of Freons and other substances in Air Conditioning, Refrigeration & Aerosol industry, the use of CFCs in the developing world is hardly impacted. The alternative refrigerants developed which have much lower ozone depletion levels are not so popular because they are way too expensive and not accessible easily. What better options we have to this continuous abuse of the world’s atmosphere. How long we will be able to manage at this rate without a major impact and are we going to pass on the world full of life threatening dangers to our Future Generations …… JUST THINK ABOUT IT
