Well, most people think that to promote tourism is a good thing for developing countries to get foreign currencies and so duely for national development and creation of jobs, in addition to income increase of peoples.
On the other hand, tourists are very egoistic for their curiosity sake and their quality of life standard.
Even some insist upon that they are promoting "Eco-Tourism", but with Big But, they do not understand the biodiversity nor what about of Eco-Tourism at all; they promot e destruction of Mother Nature which can not be cured by hundreds of years afterwards.
And those lovers of hiking from Europe walk over the virgin nature for their appetite, and they ask too much and they think they are contributing to local people of developing countries by their shoe trekking tours. However, is it so indeed?
Tourism in developing countries is promoted for Money's sake especially for the few upon Capitalism, and Eco-Tourism is not so easy thing to realize.
