A problem the world solved
- Ozone depletion could have been a disaster.
- Instead, it became a rare environmental success story.
- The world noticed the danger and acted together.
- The ozone layer is now slowly healing.
一个世界解决了的问题
- 臭氧耗损本可能是一场灾难。
- 相反,它成为一个罕见的环境成功故事。
- 世界注意到了危险并共同行动。
- 臭氧层现在慢慢愈合。
The Montreal Protocol
- In 1987, nations signed the Montreal Protocol 蒙特利尔议定书.
- They agreed to phase out CFCs and similar chemicals.
- Almost every country in the world joined.
- It is one of the most successful treaties ever made.
蒙特利尔议定书
- 1987年,各国签署了蒙特利尔议定书(Montreal Protocol)。
- 它们同意逐步淘汰氯氟烃和类似的化学物质。
- 世界上几乎每个国家都加入了。
- 它是有史以来最成功的条约之一。
The Montreal Protocol was a global agreement to… · 蒙特利尔议定书是一个全球协议,旨在……
The Montreal Protocol (1987) had countries agree to phase out CFCs — a rare global success. · 蒙特利尔议定书(1987年)让各国同意逐步淘汰氯氟烃——一个罕见的全球成功。
Safer substitutes
- Industry developed substitutes 替代品 for CFCs.
- These new chemicals cool and spray without harming ozone.
- Old fridge and air-conditioner coolants are recycled safely.
- So daily life continued while the danger was removed.
更安全的替代品
- 工业界为氯氟烃开发了替代品(substitutes)。
- 这些新化学物质能制冷和喷雾而不伤害臭氧。
- 旧的冰箱和空调制冷剂被安全地回收。
- 所以日常生活继续,而危险被消除。
Helps or harms the ozone layer? · 帮助还是伤害臭氧层?
Sort each action by whether it helps the ozone layer recover or keeps harming it. · 按照每个行为是帮助臭氧层恢复还是继续伤害它,给它们分类。
To replace CFCs, industries switched to… · 为了替代氯氟烃,工业界转向……
Companies developed substitutes that cool and spray without harming the ozone layer. · 公司开发了替代品,能制冷和喷雾而不伤害臭氧层。
Because CFCs were banned, the ozone layer is slowly starting to . · 因为氯氟烃被禁,臭氧层慢慢开始。
With CFCs falling, the ozone layer is beginning to recover — proof that global action works. · 随着氯氟烃减少,臭氧层开始恢复——证明全球行动有效。
Slow but real recovery
- CFCs already in the air last for decades.
- So the ozone layer heals slowly, not overnight.
- But measurements show it is starting to recover 恢复.
- Scientists expect it to fully heal later this century.
缓慢但真实的恢复
- 已经在空气中的氯氟烃持续数十年。
- 所以臭氧层慢慢愈合,不是一夜之间。
- 但测量显示它开始恢复(recover)。
- 科学家预计它在本世纪晚些时候完全愈合。
The ozone layer recovers slowly because CFCs already released last for decades. · 臭氧层恢复缓慢,因为已经释放的氯氟烃持续数十年。
CFCs linger for decades, so even after the ban, recovery takes a long time. · 氯氟烃滞留数十年,所以即使在禁令之后,恢复也需要很长时间。
Select all · 所有 actions that help the ozone layer. · 选出帮助臭氧层的所有行为。
Banning CFCs, using substitutes, and recycling coolants all help. Releasing more CFCs harms. · 禁止氯氟烃、使用替代品和回收制冷剂都有帮助。释放更多氯氟烃有害。
Ozone recovery is the environmental movement's best proof that global cooperation works. The world identified a threat, agreed a binding treaty, replaced the harmful chemicals, and the problem is reversing. But note the lag: because CFCs linger for decades, recovery is slow even after the ban. Acting early matters — the longer a persistent pollutant is released, the longer the damage lasts.
臭氧恢复是环保运动关于全球合作有效的最好证明。世界识别了一个威胁,商定了一个有约束力的条约,替换了有害的化学物质,问题正在逆转。但注意这个滞后:因为氯氟烃滞留数十年,即使在禁令之后恢复也缓慢。及早行动很重要——一种持久的污染物被释放越久,损害持续越久。
Why it worked:
- Scientists proved CFCs were thinning the ozone layer, and the danger was clear.
- Nations signed the Montreal Protocol and industry switched to ozone-safe substitutes — fridges and sprays kept working.
- Decades later, satellite data shows the ozone hole shrinking and the layer starting to recover — a problem caught, agreed on, and reversed.
它为什么有效:
- 科学家证明氯氟烃在使臭氧层变薄,危险很清楚。
- 各国签署了蒙特利尔议定书,工业界转向臭氧安全的替代品——冰箱和喷雾继续工作。
- 数十年后,卫星数据显示臭氧洞缩小,臭氧层开始恢复——一个被抓住、被商定、被逆转的问题。
Ozone depletion was reversed by global action. The Montreal Protocol (1987) phased out CFCs worldwide, and industry switched to ozone-safe substitutes. Because CFCs linger for decades, the layer heals slowly, but it is now starting to recover — a rare success showing that international cooperation can fix a global problem.
臭氧耗损被全球行动逆转。蒙特利尔议定书(1987年)在全世界逐步淘汰氯氟烃,工业界转向臭氧安全的替代品。因为氯氟烃滞留数十年,臭氧层慢慢愈合,但它现在开始恢复——一个罕见的成功,显示国际合作能解决一个全球问题。
