International travel makes people more prejudiced rather than broad-minded, Why will that happened? With the tendency that a rising number of people travel to other country for knowing more culture and people ,both of native inhabitant and tourist have been more prejudiced to each other .This essay will look at some reason of this trend and put forward some potential solution. Obviously, the best immediate reason why native resident have some tension to tourist is tourist may unknowingly show disrespect for local culture,for example,some people behave improperly in a religious place or even offend local people ;on the other hand,local youngsters may be attracted by the culture or lifestyle brought by tourist; this may be regarded as threat to local culture. Admittedly, there are also main reason why tourists become prejudiced to local culture , habit and people .A plenty of tourists themselves tend to generalise what they have seen or heard and develop biased view on local people or culture, e.g. they will think some certain practice are not civilised, or barbarian, inferior to their own civilisation . The possible solution are always under discussion at personal and government level, some people think that travel agencies should take the responsibility of guiding tourists about the essential of custom or tradition of the destination country, The other people suggest tourists themselves should do some research before going to some place and help protect local culture and environment, for example,they travel there by taking green transportation
