1·The destruction of Earth's ozone layer, for example, could contribute to the general process of impoverishment by allowing ultra-violet rays to harm plants and animals.
例如，地球臭氧层的破坏会使紫外线伤害植物和动物，从而导致普遍的贫瘠进程。
2·Like the ozone layer, the magnetosphere is important to life on Earth because it protects us from most of the harmful radiation and hot plasma from the Sun, deflecting it into space.
与臭氧层类似，磁层对地球生物至关重要，绝大多数来自太阳的有害射线和热等离子体都被地球磁层折射回太空，从而使我们免受伤害。
3·The damaged ozone layer can't start to heal until there is a significant reduction in chlorofluorocarbons, like Freon, that are still widely used in commerce and industry.
在像氟利昂这样仍然在商业和工业中被广泛使用的氯氟碳物质显著减少之前，被损害的臭氧层是不能开始恢复的。
4·Scientists have called for stricter controls on emissions of laughing gas, after discovering the common chemical poses a new threat to the recovering ozone layer.
在发现了笑气这种常见化学品对正在恢复的臭氧层构成新威胁之后，科学家们呼吁对笑气排放实行更为严格的管制。
5·Some raise their eyes heavenwards, launching weekly balloons to probe the ozone layer, watching with wonder the northern lights higher still.
有些人将目光投向天空，每周放出气球探测臭氧层的变化，并观看那更高之处的极光。
