Malthusian Theory

Malthusian Theory is the theory of exponential population and arithmetic food supply growth. The theory was proposed by Thomas Robert Malthus. He believed that a balance between population growth and food supply can be established through preventive and positive checks. In the absence of these 3 elements, there would inevitably be a demographic explosion, which, according to Malthus, had been underway since the Glorious Revolution in England (1688 -1689). Thus, the solution advocated by Malthus would be: In general, Malthusian Theory in general is a non-Quadrant ideology, although if put into practice it becomes an  authoritarian ideology, because of the "rules" mentioned above.
 * The moral subjection of delaying marriage;
 * The practice of chastity before marriage;
 * You only have the number of children you can support.

Classical Malthusianism
Malthusianism believes that population growth leads to a crisis when too high. For when the demand for necessitates (e.g., potatoes and bread) exceeds the ability to supply it, by virtue of having an unnecessary number of hungry mouths to feed, famine and civil unrest abounds. Thomas Malthus was writing before the industrial revolution disproved (or according to many simply delayed) his predictions. His theory reflects an early form of demand-side economics, as seen through his attacks on Say's Law which would later influence. WIP

Neo-Malthusianism
Neo-Malthusianism adapts concerns over excessive population growth to a modern, industrial society. Neo-Malthusians believe that high population density is harmful to human welfare, the environment, or both. A notable advocate of neo-Malthusianism is Henry Kissinger, who believed that excess population growth in the third world necessitated the global promotion of  feminism—especially  reproductive rights—to curb fertility rates.
