Tourism brings in large amounts of income in payment for goods and services available, accounting for 30% of the world's exports of services, and 6% of overall exports of goods and services. It also creates opportunities for employment in the service sector of the economy, associated with tourism. These service industries include transportation services, such as airlines, cruise ships, and taxicabs; hospitality services, such as accommodations, including hotels and resorts; and entertainment venues, such as amusement parks, casinos, shopping malls, music venues, and theatres.
