Today is International Day for Preservation of Ozone Layer

In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer (resolution 49/114).
States were invited to devote the Day to promote activities in accordance with the objectives of the Protocol and its amendments. The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet.
The phaseout of controlled uses of ozone depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations, but have also contributed significantly to global efforts to address climate change; furthermore, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching the earth.
The theme for this year’s celebration is “Ozone Layer Protection: The Mission Goes On.” The Montreal Protocol has so far been successful in meeting some of its targets on phasing out ozone-depleting substances. As a result, the abundance of ozone-depleting substances in the atmosphere is declining and the ozone layer is expected to recover around the middle of this century. There are, however, some remaining challenges to the phase-out of ozone-depleting substances.
"Recent scientific findings reveal the importance of the Montreal Protocol. Without the Protocol and associated agreements, atmospheric levels of ozone-depleting substances could have increased ten-fold by 2050. Concerted action has prevented millions of cases of skin cancer," United Nations Secretary-General Ban Ki-moon said in his message for the Day.
