世界節(jié)假日博覽 第152期:臭氧層保護日

There is a special day to recognize the importance of the ozone layer. In 1995, the United Nations General Assembly decided September 16th is the International Day for the Preservation of the Ozone Layer. This is the date on which countries signed the Montreal Protocol on substances that deplete the Ozone Layer in 1987. The U.N. said it was urgent we consider the “need to preserve the ozone layer, which filters sunlight and prevents the adverse effects of ultraviolet radiation reaching the Earth's surface, thereby preserving life on the planet“. It Invited every country to devote this special day to promotion, at the national level, of concrete activities in accordance with the objectives and goals of the Montreal Protocol“.

世界上有專門一天來認識臭氧層的重要性。1995年，聯(lián)合國大會決定將9月16日設(shè)為臭氧層保護日。這一節(jié)日的時間與1987年關(guān)于消耗臭氧層物質(zhì)的蒙特利爾議定書的簽署日期相同。聯(lián)合國宣稱我們考慮臭氧層保護的事迫在眉睫，“因為臭氧層能過濾陽光，防止照到地球表面的紫外線輻射的負面影響，從而保護地球上的生命。”聯(lián)合國邀請每個國家在這特殊的一天有所表示，在國家層面上采取與蒙特利爾協(xié)議的目標(biāo)相關(guān)的具體行動。


The ozone layer is a layer in Earth's atmosphere that contains high concentrations of ozone (O₃). This layer absorbs up to 99 per cent of the sun's damaging ultra-violet (UV) rays. These rays contain radiation from the sun and can give us skin cancer. They also damage plant and marine life as well as warm the temperature of the Earth. The ozone layer surrounds the Earth roughly 25km above us. Many human activities are thinning the layer. In several places, there are large holes that let in pure UV light. The chemicals used in fridges, air conditioners, foam packaging and fire extinguishers rise into the atmosphere and attack the ozone. Ozone cover is dropping by roughly four per cent a decade.

臭氧層是地球大氣層中的一層,含有高濃度的臭氧（O₃)。臭氧層吸收了高達99%的破壞性紫外線輻射。這些來自太陽的紫外線輻射會導(dǎo)致皮膚癌，也會損害植物和海洋生物，同時使全球升溫。臭氧層在地球表層上空大約25km的位置。許多人類活動正削薄臭氧層。在幾個地方，甚至出現(xiàn)了臭氧漏洞，導(dǎo)致太陽直射。冰箱、空調(diào)、泡沫包裝和滅火器中的化學(xué)物質(zhì)泄漏到大氣中，使臭氧層受損。臭氧的覆蓋率以每十年大約4%的速度減少。
