Why is tourism the fastest growing industry on planet?

While tourism is indeed an important and rapidly growing industry, stating that it's the fastest-growing industry is not accurate. Several other industries have observed higher growth rates in recent years. Economic sectors like technology, renewable energy, e-commerce, and the healthcare industry are often touted to have outpaced tourism in terms of growth.

For a more comprehensive understanding of the current situation, it's crucial to refer to the most up-to-date data and analysis provided by reputable sources such as the World Bank, International Monetary Fund (IMF), or industry-specific research organizations.
