Japanese designers are now planning an offshore magacity that could house close to a million people. The design is a giant pyramid in which up to 24 80-story buildings could be suspended from the roof. People could zoom between the buildings in a network of tubes.
While the project itself looks awe inspiring, one of the biggest threats continues to be the tsunami risk.
Implications - With population growth occurring at a substantial rate, particularly in South East Asia and India, alternatives to city living are growing in numbers. The construction of these shelters, subcities and architecturally unique megacities that can house large numbers of people is a direct result of population growth occurring faster than resource production.
