Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that were also enjoyed by the inhabitants(居民)of a country. If tourists create too much traffic, the inhabitants will become unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help a country's economy(经济).It is important to think about the people of a destination(目的地)country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the wellbeing of local inhabitants. Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country’s economy will suffer. On the other hand, if there is not enough tourism, people will lose jobs. Businesses will also lose money. It costs a great deal of money to build large hotels, airports, broad roads, and other things needed by places of interest. For example, a five-star tourism hotel needs as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money. Building a hotel is just a beginning. There must be many support facilities(支撑设施)as well, including roads to get to the hotel, electricity ,and sewers to handle waste and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.
