The population of the world has been increasing faster and
faster. In 10,000 B.C., 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
one hundred years later, the population reached 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. Others 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.
