For environmental impacts, properly planned and controlled tourism can help achieve environmental conservation but, on the other hand, tourism can cause environmental deterioration. in addition, destination planners need to be aware of two related environmental concerns. One is the conservation of important environmental features and maintenance of the overall environmental quality of the area. The other is prevention, or at least minimization, of environmental problems that can result from tourism.
Turns to the local impact, Socio-cultural impacts of destination development have engendered much comment in recent years and made tourism a controversial issue in some places. All types of new development bring change and certain types of impact. Otherwise, tourism can be, directly and indirectly, support the costs of conservation and maintenance. That is particularly important in developing countries that have limited financial resources for conservation and often higher priorities in their development programs. Some major negative socio-cultural impacts can occur if tourism is not well guided or well planned. Such problems may include
overcrowding of amenity features and transportation, shopping, and community facilities to the extent that residents cannot conveniently use them, which leads to resentment of tourism
