International Day for the Preservation of the Ozone Layer, September 16 This date commemorates the signing of the Montreal Protocol on September 16, 1987, one of the most successful environmental agreements in history, and invites us to reflect on the protection of this fragile layer of gas that shields us from the sun’s ultraviolet radiation and to continue actions for its recovery and the care of the planet. Happy celebration to all those working for the protection of the ozone layer, the reduction of harmful substances, and a more sustainable future for Earth! #InternationalDayForThePreservationOfTheOzoneLayer #OzoneLayer #MontrealProtocol #ProtectTheOzone #September16 #InternationalDays #oscarlaurag
