The hortage of houing in big citie i one of the mot eriou problem of modern living. Increaing number of people are finding it difficult to conduct normal family and work dutie becaue they either have nowhere to live or their houe are inadequate. Thi i a problem that require an urgent olution becaue it lead to ocial unret and economic inefficiency.
Some people ugget that the olution to the problem i to build more high-rie apartment, other are in favor of underground houing area. I prefer the firt idea, becaue it i cheaper to build above ground than below. Beide, people prefer to live in the open air and ee the unhine.
The econd idea i not practical. One reaon for thi i that it i dangerou to contruct living place under treet and building. Another reaon i that it would take too much time to carry out, and in the meantime the number of people waiting for houe would increae, thu making the problem wore.
