What negative impact does tourism have on the economy and culture of Sanya, Hainan? I need a complete answer.

Tourism can promote the economic development of Sanya and improve the living standard of Hainan ... but the development of tourism will also bring some harm to Hainan's ecological environment. It would be great if it doesn't destroy the ecology, but development is always beneficial and eye-catching ... This is the performance of the ecological environment in interpersonal relationships, which is normal. We should learn to use it rationally and let nature be peaceful for mankind ~

Hope to adopt
