The International Day for the Preservation of the Ozone Layer
The International Day for the Preservation of the Ozone Layer , celebrated on September 16 , highlights the importance of protecting this gaseous layer in the Earth's stratosphere. It plays a vital role in absorbing ultraviolet radiation from the sun, protecting life on Earth from the harmful effects of this radiation. The date dates back to 1987, when the Montreal Protocol was signed, seeking to control and reduce the production of substances that cause ozone depletion, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Since then, the protocol has been crucial in protecting the ozone layer. Stratospheric ozone is essential for preventing health problems, such as skin cancer and cataracts, caused by exposure to ultraviolet radiation.
