In 1994, United Nations declared September 16 was "the international day for the preservation of the ozone layer" or "Ozone Day". September 16 is the date when the Montreal protocol, related to substances that deplete the ozone layer, was signed, back in 1987. On this occasion, the United Nations Environment Programme (UNEP) broadcasts a short film explaining the history and the science of the ozone layer and actions undertaken to fight this major environmental threat and its drawbacks on the ozone layer and Earth climatic system.
