Environment problems are very common issue around the world. For example, globe climate is becoming warmer and warmer. What's more, the ice in Antarctica is becoming less and less. Polar bears have less space to live in. Futhermore, air pollution and water pollution are very serious. Natural diseater oftten happened everywhere such as earthquake, mudslide, flood and so on. More and more species are disappering every day. People do care about the environment problems because they are often suffering from these problems. Some of them had very serious dieases, some of them had a big economy loss, even some lost their lives.

Of course, China can't be escaped from these problems. Water pollution and air pollution are also very serious. Beijing is not only the capital of China, but also it is currently very famous for its fog. Heavy traffic jams often happened, flights often delayed because of its fog. Some people said the name of fog capital should be given to Beijing rather than London. As we know,  PM 2.5 is very important index to check wheather the air is good or bad. If PM 2.5 is less 50, the air is good and healthy. But it is over 150, the air is unhealthy to the people. PM 2.5 of Beijing is often over 150, sometimes it over 500, very hazardous to people. Local people are very afraid of negative effects on their health. They have to wear masks during commuter time. Many people are going to leave Beijing when weatherman forecasts PM2.5 of Binjing is over 150. Furthermore, it was reported that over 80 percents of surface water has been contaminated, of couse, including our mother river - Yellow river and Yangtze river. In addition, over 60 percents of underground water have been contaminated in China. Some people are kidding nobody can guarantee the water we drink every day is safe in China.

Why did this serious situation happen? In my viewpoints, there are some reasons as follows. Firstly, human overused much more natual resources, but, in fact, they are limited, especially in China. Most of city governments would like to attract more and more investments, so many cities are the constructed sites. They didn't care about protectation of environmet at all. Secondly, people would like to drive their own cars when they are rich, buy their own cars and want to improve living quilties. So big cities are not only very heavy traffic jamed but also air pollution is very serious.

In conclusion, I think everyone has the social responsibility to protect our environment for ourselves. We should use less natual resourses as possible as we can not only in the work but also in the daily lives. In addition, we should take public transportation as often as we can. It not only can reduce the emission of carbon diocixde, but also is very good to make our bodies good.
