During the first 2 million or so years
of its history the human population was a minor element in the world ecosystem,
with at most 10 million members. In the New Stone Age, less than 10,000
years ago, the number of humans began to increase more rapidly. The rough
equilibrium maintained before Neolithic times gave way when the human population
developed agriculture and animal husbandry and no longer had to spread
out in search of game. With the abandonment of a hunting-gathering way
of life and the rise of permanent settlements and eventually cities, the
human population underwent dramatic growth.
By the beginning of the Christian
era it had reached 250 million, and by 1650, half a billion.
Growth of population during 20th century
was very rapid. In 1994 the total world population was estimated at about
5.6 billion people. It increased nearly by 4 billions of people during
past 100 years. The most significant world trend is that death rates are
currently falling in poor and rich countries alike, while birthrates remain
high in most poor countries and low in most rich ones.
Exceptions are the
generally higher death rates of Africa and the high birthrates of the rich
The most populous countries, in descending
order, are China, India, the United States, Indonesia, Brazil, and Russia.
The U.S. population totaled about 260.8 million in 1994.
In the 1990s about
4.1 million children were born annually in the United States, and more
than 2.1 million persons died yearly. The greater number of births is due
in part to a fertility rate that has increased by nearly 20 percent since
the mid-1980s. International immigration, both legal and illegal, is another
major element in U.S.
population growth. Legal immigration has recently
amounted to about 1 million per year; illegal immigration is thought to
be several hundred thousand. In China, the world’s most populous country,
the 1994 population was estimated at nearly 1.2 billion, more than double
the 1953 census population of 584 million in mainland China. China’s annual
increase has been estimated at 1.1 percent annually.
of more than 911.6 million people (1994 est.) is increasing faster than
that of China, and if present trends continue, it will soon catch up with
or surpass China. Since the disintegration of the USSR, Indonesia and Brazil
are now the fourth and fifth most populous countries, with 1994 estimated
populations of 199.7 million and 155.3 million, respectively.
Russia has about 147.8 million people (1994 est.). It has a negative natural
increase rate of – 0.2 percent, comparable to the low or negative rates
found throughout Europe. The arithmetic is simple.
Our oceans can supply
a limited amount of fish. Farm production is limited by the amount of available
land. Once human demand for food, energy, and other materials exceeds sustainable
levels, further increase in our population will mean that we each will
get less and less and less. Today I will tell you about the most populated
country in the world, China. Chinese population exceeds 1.1 billion people.
13% of people in China live in 52 major cities. City streets are often
overcrowded with people, bicycles, cars, buses and other types of transportation.
Most Chinese people live in the countryside. They plant rice and other
crops, catch fish, and do many other jobs. Although there many people who
live in the countryside, but work in cities. Chinese are very hard and
good working people.
Like you can see from the last paragraph, China is
off to a good start, but its fast-growing population can stop China from
achieving a high standard of living. China remains one of the worlds poorest
nations despite its enormous gains in industry and agriculture since 1950.
To control rapid population growth, the government launched a massive campaign
the mid-seventies to encourage young people to marry late and to have few
children. In 1980’s, the government called for a target family size of
three, and introduced many laws to limit number of children to one, in
special circumstances, two. These measures helped to slow population growth
dramatically. Nonetheless, China continues to have about 18 millions more
new mouths to feed each year – a heave drain to its resources.
