A city without cars would be very strange, right? But Venice is such a city.
Venice is in the north-east of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.
Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 177 waterways and more than 400 bridges that can guide you where you want to go. People in Venice move from place to place by boat. They like to enjoy the scenery and the cool summer night while taking boat trips. They can talk to other people as they go along.
Venice grew out of small islands in saltwater lakes when some Italians escaped from a war over 1, 500 years ago, and built homes there.
Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences. One moment they walk across the Rialto Bridge, and there's nothing special but when they come back to the bridge an hour later, it's underwater and everyone is wearing rain shoes.
Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimetres. Another problem is the rising seawater. The temperature has risen over the years. This has made the ice of the Arctic Ocean (北冰洋) melt (融化).
Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.
Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy's biggest companies to build the MOST project, which was planned to be built under the seawater to stop the rising water. Anyway, this project is helping solve the problem.
