A very important world problem — in fact, I think it may be the most
important of all the great world problems which face us at the present time — is
the rapidly increasing pressure of population on the land. The
population of the world today is about 4,000,000,000. That is an enormous
number, yet it is known quite accurately, because there are very few parts of
the world which have not carried out a modem census. The
important thing is not so much the actual population of twenty million — about
six months’ increase in world population. Take Australia for example, there are
ten million people in Australia. So it takes the world about three months to add
to itself a population which peoples that vast country. Let us take our own
crowded country, England and Wales — forty-five to fifty million people. This is
just A. has a population of twenty million B. is a vast country that needs a bigger population C. constitutes one-fourth of the world’s population increase every year D. has a population that happens to be one-fourth of the yearly world increase

A very important world problem is the increasing number of people who actually inhabit this planet.The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.
So why is this huge increase in population taking place It is really due to the spread of the knowledge and practice of what is becoming known as “Death Control”. You have no doubt heard of the term” Birth Control”. ”Death Control” is something rather difficult. It recognizes the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind.
If we examine the amount of land available for this ever-increasing po A. Birth explosion. B. Birth Control C. Death Control. D. Technological innovations.

A very important world problem, if not the most serious of all the great world problems which affect us at the moment, is the increasing number of people who actually inhabit this planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.
In an early survey conducted in 1888, a billion and a half people inhabited the earth. Now, the population exceeds five billion and is growing fast--by the staggering figure of 90 million in 1988 alone. This means that the world must accommodate a new population roughly equal to that of the United States and Canada every three years! Even though the rate of growth has begun to slow down, most experts believe the population size will still pass eight billion during the next 50 years.
So why is this huge increase in population taking place It is really due to the spread of the knowledge and practice of what is beco A. on average, people now live to be over eighty B. we should recognize that people now live to between eighty and ninety on average C. nowadays it isn’t normal for people to die younger than eighty D. average life expectancy is increasingly being considered to be eighty or more
