Human Populations

What three factors can affect ANY population's growth rate?

• Birthrate, death rate, migration

• disease, predation, migration

• medicine, agriculture, industry

• life expectancy, sanitation, vaccines

How can population growth lead to more pollution?

• Too many people breathing causes too much carbon dioxide to enter the atmosphere

• The body heat generated by billions of people leads to an increase in global warming

• More people being born means more paper is needed to print birth certificates

• All people produce waste, so more people equals more waste

Human activities and natural events can have a large effect on populations, biodiversity and ecosystem processes. How does the growth of the human population into rural areas affect the environmental quality of the native ecosystem?

• Human population growth produces new resources that benefit the native ecosystems.

• Human population growth in rural areas help organisms evolve in order to survive in

  harsher urban environments.

• Human population growth in rural areas creates additional waste that is put back into the

  environment and lowers environmental quality.

• Human population growth in rural areas creates additional living areas for humans to

  populate, which would increase the value of the land.
