Text 2 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.
