This document discusses the impacts of tourism on destinations. It provides the example of Bali in the 1980s, which experienced negative impacts as its exotic culture and beautiful beaches initially attracted many tourists. However, overtourism led to changed culture and dirty beaches, which resulted in fewer tourists visiting. The document stresses that tourism must be managed sustainably to reduce negative impacts and conserve resources for future use, otherwise destinations risk destroying their attractiveness and losing the benefits of tourism. Sustainable tourism involves careful management of resources so they are not depleted and enough remains for future generations. Local communities, visitors, tour operators, and planning authorities all have roles in conserving destinations to ensure sustainable tourism.
