Everyone needs somewhere to live and work. In cities it is cheaper to provide hospitals, schools and the roads and there are more jobs. But as cities become larger , space and the high cost of land become a problem. The answer in most cities has been to build up rather that out. But tall buildings can be a problem in parts of the world where there are earthquakes. As a result, some architects are thinking of going down. There are plans for huge underground cities of 100,000 people with offices, theatres, libraries, hotels, sports centres and a complete transport system. The first city will be built in this century, the main problem is whether people can live without seeing the sun and sky. One idea is that people will live on the surface but travel down into the ground for their work and entertainment. However, there are other solutions. For example, in the USA there is a university building that goes 35 metres underground. People in the building get some sunlight and a "view from out of the window" thanks to a system of mirrors. Another solution may be to create weather. For example, in Tokyo there is a television station that is two metres below the ground. On a rainy night, a special shower creates the sound of rain in the studio as well.
