International Ozone Layer Protection Day
The origin of this day dates back to September 16, 1987, when the world-famous Montreal Protocol was signed. Its goal is to limit the long-term release of chemicals that destroy the ozone layer into the atmosphere. Thirty years after the signing of the Montreal Protocol, the gradual closing of the ozone hole has been observed. However, due to the chemical properties of the gases responsible for ozone depletion, it can be expected that their influence will continue for at least another 50 to 100 years.
