Malthusianism means Thomas Robert Malthus's theory of population dynamics, according to which population increase inevitably comes up against the “natural limits” of food supply because population grows geometrically (1, 2, 4, 8, 16, . . .) while food supply grows arithmetically (1, 2, 3, 4, 5, . . .). Because of this dynamic, Malthus asserted that population must be constantly checked through preventive and positive checks which will significantly affect the rest of the sociocultural system.
