http://youtu.be/2bEIf3oV5Yw Historic Venice, with its canals and centuries-old buildings, has a unique charm, but fewer people call it home today for various reasons. The city faces challenges like rising sea levels and frequent flooding, making it a tough environment for residents. Additionally, the increasing number of tourists has driven up the cost of living, pushing many locals to the outskirts. The maintenance of historic structures is costly, and strict preservation regulations make renovations challenging. The population has dwindled, creating a delicate balance between preserving Venice's rich history and adapting to the modern challenges.
