In this module we have seen that scientists disagree about the human carrying capacity of Earth. While some believe that we have exceeded human carrying capacity on Earth, others suggest that human ingenuity and innovation will allow an almost infinite increase in the carrying capacity for human existence. Many factors drive human population growth, including crude birth rate, crude death rate, and fertility rates. The age structure diagram is an important tool for evaluating the age composition of populations.
