We can begin our discussion of ―population as global issue‖ with what most persons mean when they discuss ―the population problem‖:too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to ―a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes.‖

To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality.

Often, societies were in clear danger of extinction because death rates could exceed their bi
rthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.

Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.

This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more
