A 3 minute video that explains about Ozone Depletion. How we cause them and how it affects us.

• Ozone layer absorbs 98% of damaging ultraviolet light.
• The main reason of ozone layer breakdown is the CFCs gases which are mostly found in refrigerants, aerosols and plastic products.
• The ozone depletion mostly affect in the northern hemisphere. As because of the cold temperature the CFCs affect more.
• In 1989 the Montreal protocol banned the production of ozone depleting substances.
•The CFCs in atmosphere would return to their natural state in 45 years and by then the ozone layer will shrink to smaller by 8 million sq. miles.
