人口過快增長

　　everything grows in modern times, and it seems that nothing grows as quickly as population. population keeps growing, and grows rapidly, firstly because people's living standards keep going up, with better houses, better clothing, better food, secondly because people know how to preserve themselves so as to live longer, and thirdly

　　because they have modern medicine and medical care to ensure that usual diseases can be easily cured. there is another cause for the growth of population. few countries or governments have realised the importance of family planning. on the contrary, some encourage child-birth.

　　here are some examples of population growth from 1985 to (as anticipated).

　　lima had 5.7 million people in 1985 but there were 9.1 million by . tianjin used to have 7. 9 million in 1985. by its population reached 9. 7 million.  such cities as london, osaka, moscow, beijing, karachi, delhi, jakarta, seoul, and teheran are having a similar population growth. we would not be shocked if all other cities have this rate. but some cities, like calcutta, shanghai, new york, and sto paulo boost their population even more quickly than the above-mentioned cities. tokyo had 18.8 million in 1985. the year found 20.2 million tokyo citizens. mexico city had 17.3 million people in 1985, but as population specialists had predicted, that reached 25.8 million in !

　　the population problem is a universal concern nowadays. any government is a failure if it does nothing about its population growth.
