The service sector, responsible for half of Ecuador's GDP and 45 percent of its labor force (1.9 million workers), embraces tourism, transportation, utilities, communications, parcel delivery, and financial services. Because of its beautiful geography, the diversity of its flora and fauna, and its cultural attractions, Ecuador is a popular destination for travelers and earns good profits from tourism. The other major economic force in the service industry is the informal work sector, which gives many people a means of income when formal employment is in short supply.
