Quote by Thomas Malthus
Population, when unchecked, goes on doubling itself every 25 years or increases in a geometrical ratio.
Summary
This quote, often attributed to economist Thomas Robert Malthus, suggests that if the growth of a population is not controlled, it will continue to double in size every 25 years. The phrase "increases in a geometrical ratio" refers to exponential growth, where each generation gives rise to a larger number of offspring compared to the previous one. Malthus's statement highlights the potential consequences of unchecked population growth if there are no interventions to manage resources and provide for the growing population's needs.
