Tourism (旅游业) is one of the world's largest industries. Many countries depend heavily on tourism as an important part of their economy (经济), while other countries-such as some of the smaller Caribbean island nations-are almost completely dependent on tourism.
Despite its economic advantages, tourism has disadvantages, too. While countries spend millions attracting tourists, they are also under the pressure that tourism brings.
One of the biggest problems is environmental. The building of roads and hotels can quickly destroy those very beautiful places. Development on wetlands, for example, influences wildlife; forests disappear as they are cleared to make way for buildings and to provide fuel (燃料). In addition, the tourist industry also puts a huge pressure on water people need. In dry Mediterranean areas, tourists use almost twice as much water as local people when swimming in the pool.
Tourism is also responsible for producing plenty of waste. Cruise ships in the Caribbean produce a lot of rubbish-more than 70, 000 tons each year. It even has an influence on places far away like the Himalayas, the word's highest mountain, which has more than 100 tons of rubbish sitting on it.
In spite of these problems, tourism can be good for communities and the environment. The park-entrance fees (费用) are paid for the protection of places of interest or the animals. What's more, tourism brings people closer to nature, and can give them a better understanding of the environment and the result of destroying it. This leads to pressure on local governments to protect these beautiful areas, and can result in the protection of endangered plants and animals. Also, it can provide people with more opportunities to find jobs in the tourist industry.
Although tourism has many advantages, it clearly has a bad influence as well. The challenge for local and national governments is to manage tourism so that communities can benefit economically, and yet at the same time, make sure that the tourist areas are kept for all to enjoy.
