This document discusses tourism and its psychological and cultural impacts. It notes that mass tourism began growing rapidly in the 1970s due to various economic and social factors. Tourism now forms the basis of many economies worldwide. While tourism can promote peace and understanding, the interactions between tourists and locals are often superficial. Tourism experiences can be stressful and psychologically taxing for both tourists and hosts. While some tourists seek genuine cultural experiences, most encounters between tourists and locals are brief and commercial. Tourism impacts local cultures and economies in both positive and negative ways.
