Sustainable tourism refers to tourism that meets the needs of present tourists and host communities while protecting and enhancing opportunities for future generations. It seeks to maintain a balance among economic development, environmental conservation, and socio-cultural well-being. From the perspective of Tourism Anthropology, sustainable tourism is particularly concerned with the relationship between tourists and host communities, the preservation of local cultures, and the responsible use of natural and cultural resources. Sustainable tourism involves the responsible management of tourism activities so that they do not damage the ecological and cultural foundations on which tourism depends. It promotes the conservation of biodiversity, efficient use of natural resources, reduction of pollution, and protection of landscapes and wildlife. At the same time, it encourages local communities to participate in tourism planning and benefit economically from tourism. An important feature of sustainable tourism is environmental sustainability. Tourism can cause deforestation, waste generation, water scarcity, habitat destruction, and pollution when it is poorly managed. Sustainable tourism attempts to minimize these impacts through eco-friendly accommodation, waste management, renewable energy, water conservation, controlled visitor numbers, and responsible transportation. For example, ecotourism in the Periyar Tiger Reserve in Kerala encourages nature-based tourism while supporting wildlife conservation
