The ozone layer blocks some harmful rays which the sun gives off.(臭氧層阻隔了太陽發出的一些有害射線。)

Some raise their eyes heavenwards, launching weekly balloons to probe the ozone layer, watching with wonder the northern lights higher still.(有些人將目光投向天空，每周放出氣球探測臭氧層的變化，并觀看那更高之處的極光。)

Current research suggests, though, that any risk to the ozone layer is probably not sufficient reason to abandon the idea.(不過，目前的研究表明，任何對臭氧層的威脅都不足以成為拋棄這些設想的依據。)

As the ozone layer is depleted, more UV radiation reaches the Earth's surface.(當臭氧層消失時，更多的紫外線輻射到達地球表面。)

Scientists believe the sunburns are due to increasing levels of ultraviolet radiation resulting from the thinning ozone layer.(科學家們相信灼傷是因為臭氧層變薄，致使紫外線輻射等級增加而引起的。)

This is where the planet's ozone layer sits, filtering out ultraviolet radiation from the sun.(地球臭氧層位于平流層，過濾來自太陽的紫外線輻射。)

Climate change and the depleted ozone layer are among the starkest examples.(氣候變化和臭氧層耗減就是其中最明顯的例子。)

Altering the atmosphere could also weaken solar power and reverse years of work to close the hole in the ozone layer.(改變大氣也會削弱太陽能，并讓為關閉臭氧層空洞所做的多年努力付諸東流。)

Very expensive and would require some serious rocket building to enable so many launches, which could cause problems for the ozone layer.(這個方案十分昂貴，而且為了將這么多遮陽板發射到太空中，可能需要建造許多火箭，而這可能會破壞臭氧層。)

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，地球臭氧層的破壞會使紫外線傷害植物和動物，從而導致普遍的貧困進程。)
