Nowadays tourism is considered as one the world’s major economic drives. It boosts our economy, by creating thousands of jobs and businesses (6% to 7% of the total of all jobs in all countries). It also helps build the infrastructures of a country and enriches people’s cultures and widens their world view.

Inbound tourism accounts for 30% of the world's commercial services exports, generating at least $1.2 trillion income per year or $3.4 billion a day on average (as per official data in 2011). It is also estimated that the tourism industry is responsible for 5% of the world's GDP and 25% of Small countries' and islands' total annual GDP.

In the past couple of decades, more and more people have been able to afford to travel around the world due to a significant decrease in airlines and accommodations prices. Social media has had an impact on the overtourism as well, by giving ideas of places to visit and things to do and thus encouraging people to travel more.

According to an assessment by the UNWTO, the number of international tourists is expected to increase at least 3.3% (43million) every year from 2010 to 2030.

The number of overseas travelers from china went from 10.5 million in 2001 to 150 million in 2018 alone, globally speaking that number has increased from 25 million to 1.4 billion.

The growth in the number of tourists has led to an overcrowding of cities, and originating unsustainable property price increasing which has caused a lot of tension among locals. For instance, one year, roughly 32 million tourists visited Barcelona, a city with only 1.6 million residents. In a city council survey, it was said that tourism is Barcelona’s second major problem second to unemployment, bringing the city officials to think about a new legislation aimed at curbing tourism.
