阅读理解。 As everybody knows, tourism plays an important part in the development of a country's economy, the life of the nation and international cooperation. Individually, it can enlarge our personal perspective and knowledge, and make us feel good. However, tourism can also lead to pollution and the destruction of places of interest, which is difficult to avoid. Fortunately, 'Green Tourism' is now being promoted and developed all over the world. As time goes by, people will begin to realize the importance of these places of interest. 'Green Tourism' teaches people to love nature more and to consciously protect it by enjoying its beautiful scenery and learning more about it. 'Green Tourism' is the best kind of tourism as its purpose is to appreciate and research natural environments including wild plants and animals, and of course the cultures of many places. Compared with traditional tourism, the main characteristic (特色) of 'Green Tourism' is learning more about nature and people. Traditionally, people travel the world to amuse themselves and pass time pleasantly. But 'Green Tourists' are different. They travel because they are attracted by the characteristics of protected areas. They want to make good use of natural resources but not use them up. For example, they research the wildlife, the culture and the customs or a place so that they can learn more about the history and value of the area. In short, 'Green Tourism' has a purpose and a plan, but not to pollute or destroy our places of interest. 1. What would be the best title for the text? A. Green Tourism B.
