What are the disadvantages of developing tourism resources?

Man-made destruction of the ecological environment (I deeply feel that the influx of tourists has affected the original landscape and the living environment of animals and plants in Jiuzhaigou, Sichuan in recent years)

The demise of human civilization, especially the influx of urban residents and the erosion of foreign cultures, has destroyed the local human settlement culture and civilization, not only in kind, but also in spirit. (China's ancient towns are tragic tragedies)

It is unprofessional to think of these for the time being.
