If government knew how, I should like to see it check, not multiply, the population. When it reaches its true law of action, every man that is born will be hailed as essential. – Ralph Waldo Emerson

The purpose of population is not ultimately peopling earth. It is to fill heaven. – Graham D. Leonard

The hungry world cannot be fed until and unless the growth of its resources and the growth of its population come into balance. Each man and woman-and each nation –must make decisions of conscience and policy in the face of this great problem. – Lyndon B. Johnson

Population, when unchecked, increases in a geometrical ratio. – Thomas Robert Malthus
