2015年9月16日 臭氧層能夠吸收99%以上對人類有害的太陽紫外線，保護地球上的生命免遭有害紫外線的傷害，因此被譽為地球的保護傘。每年的9月16日是聯(lián)大設(shè)立的“保護臭氧層國際日”。潘基文秘書長為此發(fā)表致辭，對全球采取共同行動，大幅減少消耗臭氧層物質(zhì)的使用，并將在本世紀(jì)中期恢復(fù)臭氧層的努力表示贊賞。他同時期待即將在今年年底舉行的巴黎氣候峰會能夠為保護地球的環(huán)境做出更大的貢獻。
　　潘基文秘書長在致辭中指出，曾經(jīng)被廣泛使用的包括氯氟烴（CFC）在內(nèi)的消耗臭氧層物質(zhì)嚴(yán)重破環(huán)了保護人類免受有害紫外線傷害的臭氧層。經(jīng)過人類共同的努力，30年前通過的《保護臭氧層維也納公約》以及在此基礎(chǔ)上通過的進一步控制氯氟烴類物質(zhì)使用的《蒙特利爾議定書》，大幅減少了消耗臭氧層物質(zhì)的使用，使臭氧層走上了恢復(fù)之路，并防止了每年可能出現(xiàn)的數(shù)百萬起皮膚癌或白內(nèi)障。
　　臭氧層破壞是當(dāng)前面臨的全球性環(huán)境問題之一，自70年代以來一直受到世界各國的關(guān)注。在1985年發(fā)現(xiàn)“南極臭氧洞”后，國際社會于當(dāng)年在奧地利首都維也通過了《保護臭氧層維也納公約》，并在此基礎(chǔ)上，于1987年9月16日在加拿大蒙特利爾通過了《關(guān)于消耗臭氧層物質(zhì)的蒙特利爾議定書》，以進一步對氯氟烴類物質(zhì)的生產(chǎn)、使用和貿(mào)易進行控制。
　　16 September 2015 Ozone layer can absorb more than 99% solar ultraviolet that is harmful to humanity so to protect the livings on earth. For this reason， ozone layer is called "the umbrella of the earth". Annual 16 September is observed as the International Day for the Preservation of the Ozone Layer.United Nations Secretary-General Ban Ki-moon gave a speech to appreciate global community’s common action to lessen the use of ozone-depleting substances and the efforts for recovering ozone layer by the middle of this century. He also looked forward to the forthcoming Paris climate conference at the end of this year to make more contribution to environmental protection.
　　In the speech， Ban Ki-moon said that use of ozone-depleting substances such as chlorofluorocarbons （CFCs） had severely damaged the ozone layer that protects people from the sun’s harmful ultraviolet radiation. Through common effort， the Vienna Convention for the Protection of the Ozone Layer had been adopted 30 years ago. On the basis of former document， and the Montreal Protocol on Substances that Deplete the Ozone Layer was drafted. The practice of two documents helped largely reduced the use of substances that deplete the ozone layer， contribute to the recovery of ozone layer and prevent millions cases of skin cancer or cataract every year.
　　Ozone layer depletion is one of global environmental problems that we are facing and has got much attention from international community since 1970s. In 1985， on discovering Antarctic ozone hole， the international community formalized the Vienna Convention for the Protection of the Ozone Layer in capital of Austria， Vienna. Further on 16 September 1987， the Montreal Protocol on Substances that Deplete the Ozone Layer was drafted to control the production， use and trade on chlorofluorocarbons.
