Plans for the world's first floating city—set in the South Korean port city of Busan, the country's second-most populous city after the capital Seoul—were unveiled this week at the United Nations headquarters in New York City.

Known as "Oceanix Busan," the newly built community will serve as the "world's first prototype sustainable floating city," aiming to be "a flood-proof infrastructure that rises with the sea," supplying its own food, energy and water.
