With the increase in population exponentially its is necessary for searching of other shelter alternatives.
Japanese technology firm Shimizu corporation has come with a new concept and designed to be a way of harnessing green technologies and creating carbon-neutral cities.
The Green Float concept involves a number of cells, each one kilometre wide, that house between 10,000 and 50,000 people.
Each individual cell would be free to float on the Pacific Ocean near the equator but could also be joined together with other cells to form larger towns and even cities, the Daily Mail reported here.
A group or modules, a collection of cells, would become a country in its own right.
The central towers would be surrounded by grassland and forests and be self-sufficient in terms of food, while livestock and other farming would take place in 'plains' also surrounding the tower - all built on a lattice of 7,000-tonne honeycomb pontoons.
The towers would be built from super-light alloys with the metal deriving from magnesium in seawater, the paper said.
The imaginative plan is designed to create a future carbon-neutral society and the Shimizu developers claim that living on cells in this way would cut carbon emissions by 40 percent.
