Tourism can create new jobs and improve the wealth of an area. Many developing countries are keen to develop tourism in order to become richer and to improve the quality of life for their people. However, when large numbers of visitors go to one place it is called mass tourism. This can have both positive and negative impacts on the area.
Tourism can create lots of different types of jobs. Most of these are tertiary jobs. This is because they involve providing a service to other people.
Some countries rely heavily on tourism and this can be a problem if tourists stop coming. Sometimes tourist numbers fall due to natural disasters such as floods or because of war or unrest. For example, some countries suffered from a fall in tourism after the 2004 Asian Tsunami and tourists were encouraged to leave Tunisia and Egypt during protests and unrest in 2011.
