Climate change and a low-carbon life
气候变化与低碳生活
There is no doubt that the world climate has been changing in recent years.
毫无疑问，近年来世界气候一直都在变化着。
Many people blame this change on gases such as carbon dioxide.
很多人把这种变化归咎于诸如二氧化碳的气体。
Animals and humans produce carbon dioxide when they breathe.
动物和人类在呼吸时会释放二氧化碳。
However, many other human activities also let off carbon gases.
然而，很多其他的人类活动也会释放出碳气体。
Anytime something is burnt, carbon is put into the atmosphere.
无论什么时候何时燃烧物品，碳都会被释放到大气层。
Cars and other vehicles burn petrol in their engines, and electrical power plants most often burns fuels such as coal and oil in order to produce electricity.
汽车和其他交通工具的发动机燃烧汽油，电力型的工厂经常燃烧煤和油等燃料来发电。
Therefore, the more petrol and electricity we consume, the more carbon we are letting off.
因此，我们消耗越多的汽油和电，释放的碳也就越多。
One thing we can all do to help solve this problem is to walk or use a bicycle when possible.
想要解决这个问题，我们都可以做到的一件事就是尽可能的步行或骑自行车。
Although we produce carbon when we breathe, the carbon we produce is much less than that produced by a car.
尽管我们呼吸时释放碳，但我们释放的碳量远不及一辆汽车所产生的含量。
Of course, there are times when we need to travel long distances.
当然，有时候我们需要走很长的距离。
In this case, public transport such as buses and the underground are always much better choices than a private car or a taxi.
遇到这样的情况，可以选择公共交通，比如公共汽车和地铁，这比选择私家车或打车好得多。
If you must drive a car, it is never good to travel alone--you should try to find other people to travel with you.
如果必须要开车的话，最好还是不要独自旅行—你应该找其他人一起旅游。
