　　Nowadays，world leaders are in Copenhagen talking about climate change. Who has such a strong power to gather them from busy work？It‘s our mother——the Earth that has told her kids to start to heal the environment for the pressing threats they are facing now.
　　It‘s commonly thought that lots of countries are blind to the protection of environment while developing the country. And as the quality of life has developed，many families have its own car. As a result，more and more CO2 has caused the earth to be a “Green House”。If no measure is taken，a large number of kids won’t see the lovely and beautiful snow in winter before long.
　　To my delight，some people have been concerned about the environment. The movie <<2012>> is just a good example. It took me 150 minutes to watch the movie. At the same time，I spent a long time considering the meaning which the movie wants to tell people. When the world is at an end，can anyone heal themselves？It‘s obvious that the answer is No. It’s commonly accepted that what the director wants to tell people is that we should take measures to beautify the environment at once or we‘ll die soon.
　　In a word，the environment pollution is a matter of life and death——a matter no country can afford to ignore. People all over the world are supposed to spare no effort to heal the world. Let‘s take action from here and now！
目前，世界各国领导人在哥本哈根讨论气候变化。谁有如此强大的力量把他们从繁忙的工作中召集过来呢？是我们的母亲——地球，告诉她的孩子们开始拯救环境因为他们现在面对的威胁。
人们通常认为，很多国家在发展的时候都没有保护环境。随着生活质量的发展，许多家庭拥有自己的汽车。因此，越来越多的二氧化碳使地球成为一个“温室”。如果不采取措施，大量的孩子们将不会在冬天的时候看到可爱的，美丽的雪。
让我高兴的是，一些人一直在关注环境。电影<< 2012 > >是一个很好的例子。我花了150分钟去看电影。在同一时间，我花了很长时间考虑那些电影想告诉人们的意义。当世界已经到达尽头，人们能治愈自己吗？很明显，答案是否定的。这是普遍接受的，导演想要告诉人们的是，我们应该采取措施来美化环境否则我们会死的很快。
总之，环境污染是一个生死攸关的问题——一个任何国家都不能忽视的问题。全世界的人都应该不遗余力地拯救世界。让我们从现在开始采取行动！
