In the late 20th and early 21st century, social and economic sustainability and the mitigation of environmental destruction have been issues of key concern. Tourism is intensely affected, as this sector is among the most polluting and least sustainable activities. Repeated pandemics, including the Ebola, AIDS, SARS, MERS, and then COVID-19, have been destroying the economy all over the world and, not surprisingly, they hit tourism the hardest of all sectors, as mass travels accelerate the spread of contagious diseases. But tourism already encountered problems long before the pandemic. As excessive tourism and the resultant pollution had already increased in the past few decades, anti-tourism attitudes spread rapidly. The current health hazards could be used to transform the unsustainable, polluting tourism into an ecologically and socially sustainable activity. This article analyzes the options we have.
