The population conference in Brasilia has now ended. One of the aims of the conference was for countries from each continent to look back at past experiences and to learn from them for the future. In Europe Population problems are different in different parts of the world. For example, in many European countries the population is getting older. The birth rate is very low because many young people have only one child or none at all. People are living longer, too. On average, men tire to 76 and women to 78. By 2050 around 25 % of the population of some European countries will be over 60 years old. This change has happened very fast within two generations. If governments had expected this change, they would have encouraged people to prepare more for old age. At the moment many old people are very lonely and often very poor. If people had expected to live so long, they would probably have saved more money for their retirement. In Africa In Africa, the problems of the future will be very different. There, the population is doubling every 24 years. Many families continue to have large numbers of children to look after older people and to help on the land. However, better medical services have increased life expectancy and more children survive to become adults. Research shows that the size of the family is connected with the standard of women’s education. If more girls had gone to school in the last 20 years, family size in Africa would probably not have continued to be so big. In Asia In contrast, the problem in Asia is not just population growth but also overcrowding in many cities. Traditionally, most people have lived in the countryside, but within the next 25 years more than 65% will live in cities. If Asian countries had expected this kind of change 20 years ago, they would have tried to provide more work and better education in the countryside. This is starting to happen now, but it may be too late. 56. What is the cause of African population problem? A. Low birth rate and increased life expectancy. B. More older people, more children. C.
