No one would deny that tourism is a booming business in China.The association could be both negative and positive and it is we who should decide.I think tourism will bring harm to environment.
The reason why people assume that tourism will bring no harm to environment is that they believe the tourism facilitating economic development is more important than the development of the environment.Yet this idea is not entirely true, as more econmic benefits may also lead to similarly harm to the environment.For example,Da Meisha in Shenzhen was the cleanest and most beautiful seaside I had ever seen. Nevertheless, with the development of tourism in Shenzhen, extensive numbers of people go to DaMeisha.  They boost tourism. Meanwhile,they bring tons of trash to DaMeisha.Hence,tourism will bring harm to the environment.
All in all,apart from tourism, the environment is similarily important to us.Thus tourism won't bring harm to the environment when it is developed reasonably.
