Helping the environment
帮助保护环境
Read this leaflet describing one way in which you can help the environment.
读这个传单，其描述了你能帮助保护环境的一条途径。
We are all aware of the many threats to the environment and the need to act in a responsible manner to protect the world which we all share.
我们都意识到环境所遭受的种种威胁，也意识到有必要以负责任的态度行动起来，保护我们共同拥有的世界。
Many people say that they are in favour of the 'green movement'.
很多人说他们有参加“绿色”运动。
However, it is often difficult to find anything practical which you can do to help, and you may feel that you cannot take any action to support the cause.
然而，要做一些力所能及的实事常常很难。你也许觉得自己采取不了任何行动来支持这个目标。
One thing you can do is to try to buy 'green' products.
但有一件事你可以做，就是尽量买绿色产品。
For example, let us consider the problem of the ozone layer.
比如，我们来考虑一下臭氧层的问题。
Around the Earth, there is a thin layer of ozone, a kind of gas protecting us from many of the harmful rays of the Sun.
在地球周围有一层薄薄的臭氧层，这种气体保护我们免遭很多有害太阳射线的照射。
A few years ago, scientists in the Antarctic became aware of holes growing in the ozone layer.
几年前，在南极的科学家首次意识到了臭氧层洞。
As these holes get bigger, harmful rays from the Sun are increasingly reaching us, causing crop damage and cancer.
随着这些洞不断变大，来自太阳的有害射线也就不断地照射到地球上，从而危害到庄稼，并引发皮肤癌。
This is a big problem in countries near the polar regions, like Australia, where skin cancer caused in part by ozone depletion is now considered a national epidemic.
这在靠近极地地区的国家是一个大问题，比如在澳大利亚，部分由于臭氧空洞而造成的皮肤癌现在被认为是一种全国范围内的流行病。
