The Italian city of Venice is facing multiple tourism threats and many residents are overwhelmed and begging for visitor control.

The Venetian population is declining, with less than half of local residents than 60 years ago. Meanwhile, 25 to 30 million tourists are set to arrive this year alone.

Venice's problems are on high alert with the UNESCO, who will decide whether to put this floating city on the World Heritage endangered list by the end of the year.
