Wouldn’t it be enough for each couple to have only one child? The grand one-child policy in China shows it is not only not enough, but that there are unanticipated problems. Many other states lack the will, the means, or the control, so the world population continues to grow.

Reading Malthus’s book on Population and appreciating “the struggle for existence” described in it, Darwin was inspired in 1838 to think of the fundamental theory of the descent of the species: “it at once struck me that under these circumstances favorable variations would tend to be preserved and unfavorable ones to be destroyed. The result of this would be the formation of new species.”
