Increasing wealth and reducing poverty: according to the official statistic reports of the World Tourism Organization, the tourism industry causes a 5-percent increase in the gross domestic product. In other words, almost 20-48% of the exports of some countries such as Tanzania and Samoa are related to tourism. Simply speaking, tourists import currency to the destination country and boost the local industries. Helping the preservation of the environment and wildlife: in essence, tourism is the voice of the wildlife and animals that are going extinct. When tourists visit the natural attractions of a country, the government will consider the reviving of those parts. For many years, the tourism industry has saved a wide range of animals and plants and prevented overhunting and illegal hunting. Getting familiar with other cultures: getting to know about other cultures is another advantage of tourism. This leads people to gradually become closer, cultural conflicts decrease, and even superstitions vanish to some extent. Tourists import their culture and take new cultures back to their home countries. This procedure can unite people and create peace all over the world, in case the cultural exchange is done properly. Increasing the domestic welfare: in many tourist countries, we witness that the welfare level of the local people has leveled up due to the improvement of tourism. This welfare includes services such as transportation, sanitary, etc. Besides, people spontaneously desire to preserve the natural, human, and historical sites of the local area.
