Cleaning Up The Ozone Layer
清理臭氧層
The scientists are devoting all their time to this problem(solving ozone layer depletion) are going to be thrilled.
一些科學(xué)家花畢生的精力來解決臭氧層損耗的問題，他們將會感到很興奮。
The problem with the ozone layer is that when certain chemicals, like chlorofluorocarbons, reach the stratosphere, they break down into chlorine and bromine,which react with the ozone and destroy it.
科學(xué)家們認(rèn)為人類造成臭氧層破壞的主要原因是一些化學(xué)物質(zhì)，像氯氟碳，當(dāng)它們到達(dá)平流層后會分解成氯和溴，然后和臭氧發(fā)生化學(xué)反應(yīng)從而破壞臭氧層。
The plan is to somehow clean the stratosphere and get rid of these chemicals. For example, some scientists have suggested using giant lasers on top of mountains to basically break apart harmful chemicals before they reach the stratosphere.
他們計(jì)劃將這些化學(xué)物質(zhì)從平流層中清除。例如，有的科學(xué)家就建議在有害化學(xué)物質(zhì)到達(dá)平流層之前，使用山頂上的巨型激光束從根本上將它們分離。
However, research proves that this would be incredibly expensive, not to mention that the side effects aren’t clear. Scrubbing out the chemicals this way might end up causing serious environmental problems.
可是，調(diào)查研究研究表明這種方法的成本很高，更何況產(chǎn)生的副作用還不清楚。用這種方法清除化學(xué)物質(zhì)可能會導(dǎo)致嚴(yán)重的環(huán)境問題。
It would be much easier to stop releasing harmful chemicals into the atmosphere in the first place. One chlorinemolecule can break apart more than one hundred thousand ozonemolecules. Why not keep it from getting there at all? If we stopped releasing harmful chemicals today, the ozone layer would probably be back at full strength by 2050.
首先，停止向大氣中排放有害化學(xué)物質(zhì)是比較簡單易行的辦法。一個氯分子可以分解十萬多個臭氧分子。為什么不阻止氯到達(dá)臭氧層呢？如果我們現(xiàn)在停止排放有害化學(xué)物質(zhì)，也許到了2050年，臭氧層空洞就會消失了。
