Why sustainable tourism term is difficult to define?

Sustainable tourism is difficult to define because it encompasses a wide range of practices and principles that can vary significantly based on cultural, environmental, and economic contexts. The term often integrates complex concepts such as conservation, community engagement, and responsible resource management, leading to differing interpretations among stakeholders. Additionally, the balance between environmental sustainability and economic viability can create competing priorities, making a universally accepted definition elusive. This complexity is further compounded by the evolving nature of tourism itself, influenced by changing consumer preferences and global challenges.
