Human activities have negative effects on the natural environment as mentioned in many reports. Could this situation be retrieved or just getting worse? Some people believe the human activities will definitely break the balance of the nature, not only in metropolis but also some rural areas. Shanxi is an inland province of China, which is famous for its abundant coal mine. However, after dozens of years' exploitation, the land is riddled with cavities by inordinate mining. The animals lose their home, the trees are cut down and the land itself cannot even hold the soil. In that case the problem seems to be insoluble. On the other hand, some examples demonstrate that the situation could be improved due to the efforts of people. The Thames River in England was once the most beautiful river of the world. But it is polluted due to the increasing of population in London and the industrialization. The birds and fished disappeared for many years and hence the river was considered to be a dead river. Finally, people realized the importance of keeping a sustainable relationship with the nature. Laws were made to control the emission of polluted or harmful water to river, and hundreds of sewage treatment plants were set up to purify the water. After 20 years' governance, the river was brought back to life. The fishes were back, the birds were back and people's smiles were back. So as people's awareness on protection of natural circumstances increased, more and more measures are adopted to protect the environment and deal with the problems that already occurred. And human activities will do less and less negative effects on plants and animal species as time goes by.
