The world population is now passing the 4 billion mark, and at the present rate of increase it would double twice to about 15 billion by the year 2050. Yet there are those who say that it has already reached a ceiling and will do well to maintain its present level; that shortages of all kinds, especially of foodstuffs, will prevent further rise, even if birth control does not. Many individuals already born will be alive in the year 2050; it is hardly very informative to know that they will be accompanied on the earth by between 4 and 15 billion people. The following pages are an attempt to narrow the range.
