Nowadays, the world’s population has been exploding and dead risks have threatened the Earth. Therefore, human beings try to find and build ideal cities so that they can enjoy their comfortable life in peace and safety.
Sub Biosphere 2
Sub Biosphere 2, a self-sustainable underwater city, was designed by UK-based designer Phil Pauley. It is set up for tourism and oceanographic life sciences as well as plant and animal habitation. The unique underwater habitat can sustain all of its life support systems like air, water, food, electricity, and other resources through an innovative control of variant atmospheric pressures occurring at depth. Sub Biosphere is able to float on top of the water or submerge and travel along rails all the way to the ocean floor.
