People are building a new kind of city. This type of city will not be on land. It will float on the ocean.
The first floating city will be in French Polynesia. That is in the South Pacific Ocean. Construction will begin soon. The builders hope to finish it by 2020. To begin with, the first floating city will be the size of a soccer field. But it will grow. It will have homes and parks. There will also be schools, shops, and restaurants.
Why build floating cities? Floating cities are safe from flooding. As the sea rises, so will the cities. They can be moved to a new place. And they will let more people live near the ocean.
