Aug 4, 2025

Overview

This lecture examines the Malthusian Theory of Population, its historical impact on government policies, and ongoing debates about overpopulation.

Malthusian Theory of Population

  • Thomas Malthus argued that population grows faster than food production, leading to inevitable shortages.
  • He believed population increases geometrically (exponentially), while food supply increases arithmetically (linearly).
  • According to Malthus, unchecked population growth results in famine, disease, and conflict as natural checks.

Historical Impact and Policies

  • Malthusian ideas influenced laws and policies aimed at controlling population growth.
  • These policies sometimes caused hardship and suffering, including restrictive or coercive measures.
  • Neo-Malthusianism emerged later, advocating for birth control and family planning.

Current Relevance and Debates

  • The video questions whether overpopulation remains a problem in the modern world.
  • Advances in technology and agriculture have challenged Malthus’s predictions about food shortages.
  • There are ongoing discussions about sustainable development and responsible resource management.
