Travel was not always as popular as it is today. In the past only wealthy people could travel to other countries. But in recent years, one person in ten visited a country far away from home. More people travel today because there is a growing middle class in many parts of the world. People now have more money for travel. Special airplane fares for tourists make travel less expensive and thus more attractive than ever before. One person does not travel for the same reason as another. However, most people enjoy seeing countries that are different from their own. They also like to meet new people and try new foods.
