Global Warming 全球变暖问题Many nations are facing the problem of global warming.Global warming, I think, which is of great destroy to the environment, can make our earth hotter and hotter. So a closer attention should be paid at the issue.It is mainly caused by carbon dioxide, a heat-trapping gas or greenhouse gas.On the one hand, the main reason which makes the earth warm up is because of human activities, such as cutting down trees, driving cars and so on. On the other hand, the earth‟s atmosphere is steadily at an average 15 oC,….. during the industrial revolution, lots of factories formed, releasing more and more carbon dioxide. By means of trees can we get paper napkins and some wooden products; by means of plastic bags can we make shopping easily and conveniently. What‟s more, They are the human activities which we talk about, and thus global warming is more and more serious.As far as I know, Although the highest mountain in China is 8848 metres high, do you know the snow on the mountain has been melting? It is said that because it seldom snows in China, but I am sure that it does not hold water. The real fact is that we human beings do something harmful to the nature. Maybe it is angry and now it wants to revenge us.With rapid development, we must find some ways to solve such a serious problem. We should take some efficient actions to protect our environment. For instance, we can use bags made of cloth instead of using plastic bags. We can walk to school instead of going there by car or by bus. We should plant trees instead of cutting them down. If we did the small things by ourselves, we would not make our earth become warmer than before. We even can release some space mirrors into the Earth orbit to reflect sunlight back into the space. Scientists it is useful to paint the roads and roofs white.There is no doubt that global warming would be stopped in the near future. Development and the Environment环境与发展No doubt that the worsening environment has become the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion. Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say thatdeterioration of the quality of the environment threatens the existence of mankind itself. Some people are of the opinion that the environmental problem is the price we have to pay for economic development. But I do not think that this argument is valid. After all, what is the point of economic growth if people's lives are adversely affected by worsening environmental pollution?There is plenty of evidence to show that sustainable development can be achieved by balancing economic growth with protection of the environment. The key to achieving this is to make people aware of the seriousness of the problem. Both governments and ordinary citizens should join hands to make this world a better place to live in, not only for ourselves, but also for future generations.环境与发展不可否认的是环境恶化已成为当今世界上人们最担心的事了。
