Life in the future In 2264, the global population will have reached the maximum level and there won't be enough space for people to settle in. If all of the lands are filled with humans, why not use the ocean as a residential place? In the ocean, people can live in a building that can act as a city. If the building is built like the lotte Tower in South Korea, there could be living spaces in addition to other infrastructures to accommodate human life. Therefore, in the future, this type of building would be constructed in the ocean because of the lack of living space.
