Thomas Malthus：An Essay on the Principle of Population, Excerpt 28

Taking the population of the world at any number, a thousand millions, for instance, the human species would increase in the ratio of--1, 2, 4, 8, 16, 32, 64, 128, 256, 512, etc. and subsistence as--1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. In two centuries and a quarter, the population would be to the means of subsistence as 512 to 10: in three centuries as 4096 to 13, and in two thousand years the difference would be almost incalculable, though the produce in that time would have increased to an immense extent.
