About six billion people live in the world today. If all these people were distributed evenly over the earth, there would be about seventy-seven people living on each square mile of land. This is not the case, however. Some areas are very crowded, while others are almost empty. The three most heavily populated parts of the world are East Asia, South Asia, and Europe.
The world’s population is about twice as it was only fifty years ago. Larger food supplies and better medical care help to explain this increase. In the past, large numbers of babies were born each year, but many children died of hunger or disease before they became adults. Today, people are not having any more children than before, but more children are living to become adults and to have families of their own. It is mainly for this reason the world’s population has been growing so rapidly. If it goes on at its present rate, world population will probably double again within only thirty-five years.
The rapid growth of population is a serious problem for all the people of the world. Each year, human beings are using larger and larger amounts of the earth’s resources. Many exports believe that population growth must slow down if people everywhere are to have an opportunity to meet their needs.
