world in the year 2000 and man's place therein will be determined by the
manner in which organized humanity confronts several major challenges.
If sufficiently successful, and mankind escapes the dark abysses of its own
making, then truly will the future belong to man, the only product of
biological evolution capable of controlling its own further destiny.
Social organizations, through their political leaders, will determine on
peace or war, on the use of conventional or nuclear weapons, on the
encouragement or discouragement of measures to limit the growth of
populations, on the degree of increase in food production, and on the con-
servation of a healthy environment or its continuing degradation.
These and lesser decisions will affect the composition of the human
species. Some major population groups will grow in numbers, others will de-
cline, relatively or absolutely, as they have in the past. Thus, in the seven-
