The Problem of Human Population
      people on earth. But today on the same planet we have about more than 5,000 million people, a figure 13 times as big as that of 1,000 years ago. We can see from the above graph that human population had been incrcasing almost all the time. The Industrial and Agriealtmal Revolution which began in 1650 contributcd a little to the growth of population. Then the emergence of modern medicine in 1850, which greatly Iowered the deathrate, caused the popolatlon to increase rapidly.
      During the past half ccntury, the world's population has been increasing at a fantastie speed, and we are now faced with the so-called problem of "population explosion". With more and more people coming into this world, human beings are now confronted with the danger of food shortages because the land on which man can grow grains remains the same. If not controlled,the population of the world will amount to 7,000 million in the year 2,000.
      To solve the problem of the "population explosion", or in other words, to save man kind, it is extremely necessary to practise birth control in some areas of the world.
人口问题
      据估计1000年前地球上的人口不到4亿。但足,如今在同一个地球上约有50多亿人口,这是1000年前的13倍。从上图可以看出,人口几乎年年都在增长。1650年开始的工农业革命对人口增长起了推动作用。接着在1850年出现的现代医学,大大降低了死亡率,使人口急剧增长。
     在过去的半个世纪,世界人口增长突飞猛进,我们现在正面临着所谓“人口爆炸”问题。随着越来越多人来到这个世界,人类现在正面临着食品不足的问题,因为人类种庄稼的土地仍然是那么多。如果不加控制,世界人口到2000年将增加到70亿。
     为了解决“人口爆炸”问题,或者说为了拯救人类,极有必要在世界的一些地区实行人口控制。
