Protests in Spain will spread if European officials fail to address mass tourism's negative effect on the lives of residents, UNESCO's Peter Debrine told "Squawk Box Asia" on Monday.
He cited the banning of large cruise ships in Venice, Italy, in 2021 as an example.
"Cruise ships are no longer going through the Grand Canal."
Cruise ships now dock farther from Venice, which helps the structural and environmental integrity of the city.
But travelers also play a role in curbing mass tourism, said Debrine.
