How does tourism destroy the environment?

Everyone wants to go on a holiday to scenic places. As a result, more and more hotels, roads, and airfields are built in and around tourist spots. A huge amount of water is required in the hotels to provide hygiene and catering services to tourists. A lot of waste water and garbage are also produced in the process. Tourists often litter the places they visit with polythene and leftover food without thinking about the damage they are causing to the environment.
