Chapter 6:  The Human Population and Its Impact


Section 1:  How Do Environmental Scientists Think about Human Population Growth?

​Concept 6-1:  
The continuing rapid growth of the human population and its impacts on natural capital raise questions about how long the human population can keep growing.

Section 2:  What Factors Influence the Size of the Human Population?

Concept 6-2A:  
Population size increases through births and immigration, and decreases through deaths and emigration.

Concept 6-2B:  The average number of children born to the women in a population (total fertility rate) is the key factor that determines population size.

Section 3:  How Does a Population's Age Structure Affect its Growth or Decline?

Concept 6-3:  The numbers of males and females in young, middle, and older age groups determine how fast a population grows or declines.

Section 4:  How Can We Slow Human Population Growth?

Concept 6-4:  
We can slow human population growth by reducing poverty, elevating the status of women, and encouraging family planning.
