据联合国根据政府数据所作的保守估计,如果不给予计划生育以大量的支持,在下个世纪,世界人口将可能达140亿左右。1830年,这个地球上居住着10亿人,才过了一个世纪,人口就达到20亿;又过了30年(1960年),人口数突破30亿;再过了15年,40亿;而到1986年——仅过了11年,50亿。目前世界人口数为54亿,到1995年可能会达到60亿。
According to a conservative estimate made by the United Nations on the basis of government data, if we do not give much support to family planning, the world population will probably reach about 14 billion in the next century. In 1830, there lived 1 billion people on this earth. Only a century passed and the population reached 2 billion. In another 30 years (1960), the population exceeded 3 billion. In another 15 years and 4 billion, By 1986 - just over 11 years, 5 billion. The current world population is 5.4 billion and by 1995 it may reach 6 billion.
