Who can provide some examples of environmental damage caused by the development of tourist areas?

/2005/06/08103930071.Xiagei Hot Spring in Shangri-La County, Yunnan Province is a typical geological landscape formed by modern hot springs. It is of great ornamental and scientific research value, and the spray (hot air) hole in the scenic spot is especially rare. However, in the process of tourism development, developers tried to turn the spray hole into a "sauna" place without knowing the geological structure and laws of the spray hole, which seriously damaged the rare tourism geological landscape. Another underground spring in this county, Tianshengqiao Caiquan, lost the natural conditions for the reappearance of Caiquan because of modern decoration. Some places in Shangri-La, a pure land in the southwest, are also doomed under the tide of tourism development. Many experts from "China Landscape Architecture Society" pointed out that in recent years, the dislocation development of some places has led to the artificialization, commercialization and urbanization of many national scenic spots, and some scenic spots are becoming playgrounds for eating, drinking and having fun, and the natural ecosystem has suffered unprecedented damage. For example, the Yulong Snow Mountain in Lijiang has set up three ropeways, each extending to the core area of the nature reserve. Among them, the Yulong Snow Mountain cableway with a total length of nearly 3,000 meters extends to the Snow Mountain with an altitude of 4,506 meters, carrying 426 passengers in one direction every hour. The construction and operation of these ropeways have brought ecological disasters to nature reserves. With the influx of tourists, ancient glaciers were destroyed and some glaciers began to melt. Alpine vegetation and wild flowers are trampled and destroyed by tourists; The number of wild animals has dropped sharply, and the rare animals that were planned at that time are hard to find now. The destruction speed of the ecological environment of Yulong Snow Mountain surprised experts all over the world. More seriously, some scenic spots were developed without planning.
