Step 1: Concept Overview:
The problem pertains to a fundamental concept in demography and economics concerning the interplay between population expansion and the availability of resources.
Step 3: Detailed Explanation:
This principle was formulated by the English economist Thomas Robert Malthus in his 1798 publication, "An Essay on the Principle of Population". The central tenet, known as the Malthusian Theory of Population, posits:
\[\begin{array}{rl} \bullet & \text{Population Expansion: Unhindered, population growth follows a geometric progression (e.g., 2, 4, 8, 16, 32...).} \\ \bullet & \text{Resource Expansion: The supply of food and other resources increases at a slower, arithmetic rate (e.g., 1, 2, 3, 4, 5...).} \\ \end{array}\]Malthus contended that this imbalance would inevitably result in a crisis point (a "Malthusian catastrophe") where population exceeds resources, leading to widespread famine, disease, and conflict.
Step 4: Conclusion:
The theory was advanced by T. R. Malthus.
