How does the size of the human population change with time? As civilization advanced Section 5-3 human population growth. Explain why population growth rates differ in countries throughout the world. Section 5-2: Limits to Growth - Limiting Factors - Density Dependent and Density Independent Limiting factors are those factors that keep a population from growth exponentially. Why did the population grow slowly for most of human existence? Examples are woolly mammoths and saber-toothed tigers.
