My opinion

Actually, I think the tourism industry can drive the local economic development.

The tourism industry has always been said to be "industries without smokestacks , but "no smokestacks " doesn't necessarily mean "no pollution" or damage to the environment.

In fact, people in the process of traveling cause pollution to the local area, like  carbon dioxide emissions from airplanes or drop trash with abandon, even random to sculpt in historic sites.

The authorities need to introduce laws to clampdown on certain behaviour

and tourists should be self-discipline,

Although tourism can bring economic value, but the other side of the coin is that damage caused by tourists. If every tourist can travel with good quality and energy-saving carbon reduction methods, I don't think tourism is harmful, is a good way to improve the economy.
