flocking to different destinations over the country, air travel, car travel and train travel are adding to the planet’s pollution crisis and this is becoming a serious problem. Tourism development must accompany a sharp rise in traffic; however, we have to admit that the scenes of packed vehicles around the tourist attractions are not a pleasant view, let alone the exhaust fumes emitted. Besides, in some mountainous areas, in order to attract the tourists, trees are cut down to build the roads and hotels to facilitate people’s exploration of scenic spots, which itself serve as the evidence of negative effects imposed on the local environment. In addition, some tourists’ lack of awareness of environmental protection leads to damage on a large scale, from the garbage spread around to the animals scared away or even killed by the tourists, which badly damages the balance of the natural environment. In short, to develop tourism at the cost of environment is proved wrong beyond doubt. Thus, we need to find a balance between satisfying the needs of tourists and reducing to a minimum the damage tourism causes.
