Venice, Italy

Due to its distinctive and extensive network of interconnecting canals, Venice, Italy is also known as the Floating City or the City of Bridges. Venice remains one of the most unusual tourist destinations since there is only one major road, a few side streets, and a few minor bridges, lanes, and pedestrian trails.

But right now, Venice is dealing with a number of issues that put its long-term survival in jeopardy. The largest one is global warming since portions of it are already being submerged by rising sea levels. Floods are also becoming more regular and severe; in fact, one in 2019 managed to submerge almost 70% of the city.

According to a recent research, portions of the city are sinking alarmingly fast in addition to people drowning. They also discovered that several structures in the city are gradually leaning eastward, as if that weren't enough.
