空氣污染 Air Pollution
In the past few decades, our Earth has changed a lot, but to the bad direction. Among these changes, the air pollutions resulting from a huge number of automobiles and coal-burning is almost the severest. The severe air pollution alarms humans of the heavy load we have exerted on Earth by our insatiable production and usage of automobiles. However, with the deepening of urbanization, more cars are needed, which will make the air pollution worse. Therefore, the following actions should be taken. First, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. Second, try hard to develop possible transportation means, which are enviromental friendly. So that the citizens can reduce the dependence on cars. In short, our humans should take responsibilities for the air pollution and have to find ways to solve this problem.
在過(guò)去的幾十年中，我們的地球發(fā)生了很大變化，但是是往壞的方向。在這些變化中，大量汽車和煤燃燒產(chǎn)生的空氣污染是最為嚴(yán)重的。嚴(yán)重的空氣污染警告人類，我們無(wú)休止的的生產(chǎn)和使用汽車給我們的地球帶來(lái)了沉重的負(fù)荷。然而，隨著城市化的加深，汽車的需求量也越大，這會(huì)導(dǎo)致空氣污染更嚴(yán)重。因此，我們應(yīng)該采取以下行動(dòng)。首先，我們應(yīng)該運(yùn)用最尖端的技術(shù)，以新型能源作為化石燃料的替代品。其次，努力尋找可能的環(huán)境友好型交通方式。這樣城市居民就可以減少對(duì)汽車的依賴。簡(jiǎn)而言之，人類應(yīng)該承擔(dān)空氣污染的責(zé)任，尋找解決這一問(wèn)題的方法。
