2. WHILE YOU READ:
The population of the world has been increasing faster and faster. In 10,000 BC., there were probably only 10 million
people. In A.D. 1, there were 300 million. It took 1,750 years for the world population to reach 625 million. In 1850, only
100 years later, the population reach the figure of 1,300 million. In 1950, the figure had more than doubled to reach
2,510 million. In 1985, only 35 years later, there were 4,760 million people. In 2000, the world’s population was about
6,6 billion, and by 2015 it is expected to be over 7 billion.
Does the earth have enough resources to support this many people? Different scientists give different answers to this
question. Some say that there are enough resources to support 8 billion people. Other say that we must limit
population growth because our resources are limited. Only 10 percent of the earth’s land can be used for farming and
another 20 percent for raising animals. There is a limit to the water we can use. There are also limits to the amounts of
petroleum, iron, silver, gold, and other metals.
Research has show that the average Third World woman has more children than she wants. Among the women who do
not think they have too many children, half of them do not want any more. However, although millions of women want
to limit the size of their families, they know of no safe way to have fewer children. Safe birth – control methods for
family planning are not available to them. It is time governments and international organizations did something to help
them so that the world population growth can to decrease instead of continuing to increase.
