Tourism has the power to affect cultural change. Successful development of a resource can lead to numerous negative impacts. Among these are overdevelopment, assimilation, conflict, and artificial reconstruction. While presenting a culture to tourists may help preserve the culture, it can also dilute or even destroy it. The point is to promote tourism in the region so that it would both give incomes and create respect for the local tradition and culture.
There are also both negative and positive impacts of tourism on the local ecology. Tourism often grows into mass-tourism. It leads to the over consumption, pollution, and lack of resources. However, from the ecological point of view tourism is often more acceptable and preferable than any other industrial production, as it is environmentally friendlier. The problem is that it is not easy to change the traditional way of life of the local communities. It often creates pseudo conflicts. Undoubtedly in some regions or countries the alternative industries are even more harmful to the environment than tourism.
Besides that in many countries of Asia and the Pacific, for example in Cook Islands, Samoa and others, tourism is the main source of income or the friendliest to the environment. It is at least better than chopping down the forests or destroying coral reefs.
