人口问题是与环境问题有密切的互为因果的联系,在一定社会发展阶段,一定地理环境和生产力水平条件下,人口增殖应保持在适当比例内.
The rapid growth in world population caused many problems.In particular,some over-population,economic growth in developed countries,affecting the country's economic development,social stability and people's living standards,many of the problems to human life.World population problems
In order to solve the problem of excessive population growth,the human must control their own,so that planned fertility,the population growth and socio-economic development compatible with the environment,resource coordination.
世界人口的迅猛增长引起了许多问题.特别是一些经济不发达国家的人口过度增长,影响了整个国家的经济发展、社会安定和人民生活水平的提高,给人类生活带来许多问题.人口数量问题困扰世界
为了解决人口增长过快的问题,人类必须控制自己,做到有计划地生育,使人口的增长与社会、经济的发展相适应,与环境、资源相协调.
In the 1970s,it was considered to account for the population at that time had lived on earth for 75% of the total population.The widely quoted statistics are too affected by the impact of the 20th century population explosion - the proportion of it is incredibly high.To get a more accurate result,we must determine when modern humans from the beginning,the birth rate is the number,and the history of how many people lived in the end.Generally believe that modern man is in the 50,000 years ago.We can imagine,does not limit the population was born,and life expectancy is very short,which resulted in a young population and higher fertility rates - every mother's health at around six to eight children.To the Middle Ages,the birth rate began to decline long.The record shows that since the 18th century,when the industrialized countries,the birth rate continues to decline.U.S.demographers Carl - Hao Po (CarlHaub) that,before the advent of agriculture,hunting in the way,the world's population is only about 5 million to 10 million.Light of the message,to the 1st century AD,according to the Roman,Chinese and Mediterranean off the census,the world's population has grown to 300 million.Application of this population a higher birth rate,we can estimate that so far a total of life on Earth over approximately 106 billion people.We now have 6.1 billion people,accounting for life on Earth has had a total population of 5.7%.In 1900,only 16 million people around the world,but developing countries rapid population growth led to the proliferation of the world's population,so we had a population proportion of the population of the Earth on the rise.
在20世纪70年代,有人认为,当时的人口要占地球上曾经生活过的总人口的75%.这一被广泛引用的统计结果过于受20世纪人口爆炸的影响——比例实在是高得令人难以置信.要想得到一个比较精确的结果,我们必须确定现代人类是从何时开始的,出生率是多少,以及历史上到底生活过多少人.普遍认为,现代人是在5万年前出现的.我们可以设想,当时是不会限制人口出生的,且人的寿命都很短,这就导致一个年轻的人口结构和较高的生育率——每个母亲大约会生6到8个孩子.到了中世纪,出生率开始长时间地下降.18世纪以后的记录表明,当时的工业化国家,出生率在持续下降. 美国人口学者卡尔－郝伯（CarlHaub）认为,在农业出现以前,在以狩猎为生的方式下,全世界的人口大约只有500万到1000万.科技之光消息,到了公元1世纪,根据当时罗马、中国和地中海地区的断断续续的人口普查,世界人口已增长至3亿.对这个人口应用一个较高的出生率,就可以估算出,迄今为止地球上总共生活过大约1060亿人.我们现在有61亿人,占地球上曾经生活过的总人口的5.7%.在1900年,全世界只有16亿人,但是发展中国家人口的快速增长导致世界人口的激增,所以我们现有人口占地球曾有人口的比例在上升.
