However, the question that the moon people asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Under ground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The Chunnel,a tunnel(隧道)connecting England and France, is now complete.
But what about underground cities? Japans Taisei Corporation is designing a network of underground systems, called Alice Cities.The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome(太阳能穹顶)would cover the whole city.
