Cities on the ocean, which are populated by thousands or even millions of people – it is possible and it is the dream of the future. 71 percent of the Earth’s surface is covered by water – while the oceans hold about 96.5 percent of all the water on Earth.
This means that it is very likeable that in the future we will be building houses and even complete cities in the middle of the oceans.
Yes – there are a lot of challenges and it would take some time, but the researchers from www.seasteading.org are certain that it is possible and they have started a floating city project which will finish in 2020.
