People may worry about Venice disappearing under water, but the city has been battling that threat successfully for centuries. The battle it is losing is that of abandonment: Venice’s small neighborhoods and squares are abandoned. There are no people shopping no elderly smoking and chatting, no children playing ball.
The locals are leaving. Apartments are being purchased by foreigners and used only sparingly, boarded up for the rest of the year. In a city of no cars, the silence is deafening. The tourists drift around, but not through residential neighborhoods, and most of the tourists are here only for a day. The population is down by two-thirds over a couple of decades, and it continues to decline.
By the time water covers Venice, no one might notice—the people will long have been gone.
