Without proper planning, tourism can cause problems. For example, too many tourists can crowd (挤满) public places that are also enjoyed by the local people. If tourists create too much traffic, the local people become unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy (经济). Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. It is a fact that tourism provides local people with a lot of chances to work, but at the same time it also means that other parts of the country’s economy may suffer. Many other industries will be badly affected.
On the other hand, if there is not enough tourism, people may lose jobs. Businesses may also lose money. It costs a great deal of money to build large hotels, airports, first - class roads, and other support facilities (设施) needed by tourist attractions. For example, an international - class hotel may cost as much as 50 thousand dollars per room to build. If the room is not used most of the time, the owners of the hotel will lose money.
Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the well - being (安乐) of the local people.
