The anti-fulfillment results of overpopulation—
The Course and Direction of Human Destiny.
Population density produces stress..., a formidible crop of neuroses and ill-health... squalor and deformity. Shall we become the world's guide, or its cancer?
Mass production reduces individual initiative... causing reductio ad absurdum.
Will mankind undertake the conscious direction of process of human evolution, including its own reproduction.
All of the space available (of earth)... will be taken up in less than 1000 years — a flick of man's time potential.
World Population and Human Destiny — Sir Julian Huxley, speaking before the Planned Parenthood Federation in New York on the occasion of the presentation to him of the Albert Lasker Award.
