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 *** 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。炎炎英文培训网

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。

人口普查英语作文

The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleoecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one m illion B. C., followed the innovations of tool making and tool using. But when the new power from the use of tools has been exploited, the rate of world population growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when mankind began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These o episodes suggest that the third great change, the present rapid growth, which began in the West beeen 250 and 350 years ago, may also slow down when, or if, technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either way - contrary to popular belief in constant geometric growth - population can be expected in the long run to adjust to productivity. And when one takes this view, population growth is seen to represent economic progress and human triumph rather than social failure.

Progress in science and the improvement of living conditions have led m the rapidgrowth of the world population. Modern medical science, for example, has made it possible for babies to grow up healthily and for people to live longer.With improved living conditions, particularly in the countryside, people tend to have larger families. As a resuit, the world population has increased so rapidly that it has now exceeded 5 billion. But the overgrowth of population presents a threat to the existence of human society. A large population demands a great deal of food supply and shelter space. However,the limited productivity and scarce natural resources can hardly meet the needs of the ever-Increasing population. Thus in the long run, the overgrowth of the world population will only harm mankind.4ia英语作文网To guarantee the steady development of human society, mankind must realize the consequences resulting from a fast population growth and the importance of carrying out a family planning programme.

Li Ming's brother gave him a good gift:a beautiful new mobile phone.And there are a lot of funny games in it such as the Fruit Minja and Tom Cat. Li Ming likes it very much so he wants to take it to school.But his parents don't allow him.If he takes it to school,his parents won't give the mobile phone to him.

In my opinion,I think that it's bad for students to take the mobile phone to school.If students do this,they won't get good grades on their schoolwork.Anyway,it is also a waste of time.
