International Tourism

Cross-border travel and tourism are referred to as international travel. Due to globalization, tourism is becoming a well-liked pastime worldwide. Tourists are persons who "travel to and remain in places outside their typical surroundings for not more than one consecutive year for leisure, business, and other objectives", according to the World Tourism Organization. According to the World Health Organization (WHO), there may be up to 500,000 passengers traveling at once.

International tourism has significant negative effects on the environment, which are made worse in part by the issues brought on by air travel as well as other problems, such as wealthy visitors who bring lifestyles that put a strain on local infrastructure, such as water and waste systems, among other things. The World Tourism Organization reports that international tourism receipts were US$1.7 trillion in 2018, an increase in real terms of 4% over 2017. In 2019, there were 1.460 billion international tourist arrivals worldwide, with a growth of 3.7% as compared to 2018.
