Some nations think they must have more and more babies, more and more people, if they are to remain strong and free.
Actually, this is not so. Very often in history, small nations have conquered large ones. It’s not so much the size of the army as its organization and the technical level of its weapons. Thus, Greece took over Persia in the 300s B.C., Great Britain took over India in the 1700s, even though Persia and India had far bigger population than Greece and Great Britain.
If a nation wishes to avoid being dominated by its neighbors, its best chance is to raise its standard of living and its level of technology.This can be done best by not allowing its population to grow to such a point that it is sunk in misery and poverty. In fact, the worst way in which a nation can try to avoid being dominated by its neighbor is to increase its population to the point of misery and poverty.
If every nation tries to compete with its neighbors by raising its population, then the whole world will be sunk in misery and poverty. The nations will become weak in a disaster that will leave nothing behind that is worth dominating. No one will have gained anything. Everyone will have lost everything.
Once all this is understood, and people generally agree that population growth must not be allowed to continue, they must also come to understand how that growth can be stopped. Population grows because more people are being born than are dying. There are two ways, then, in which the growth can be stopped. You can increase the number of people who die until it matches the number of people who are being born. Or else you can decrease the number of people who are born until it matches the number of people who are dying.
The first method—increasing the death rate—is the usual way in which population is controlled in all species of living things other than ourselves, but we don’t want that, for disaster lies that way. The intelligent way is to reduce the birth rate. But how can the birth rate be reduced?
