13.3 Challenges of Overpopulation
  • Objectives
  • Relate how overpopulation affects natural
    resources, energy demands, and biodiversity.
  • Hypothesize how the availability of resources
    affects population growth

3
Affects of Overpopulation
  • Rapid population growth directly affects the
    global ecosystem. Why?
  • An increase in population places a greater demand
    on
  • the space needed to sustain large numbers of
    people.
  • natural resources, such as minerals, fuels and
    food.

How Humans are Affected
  • Human health problems
  • More crowding
  • more contact among people
  • more illness
  • More disease related to
  • malnutrition,
  • poor hygiene and
  • lack of medical facilities

6
Controlling Population Size
  • Birth control
  • Large-scale efforts
  • to educate people
  • provide effective methods.
  • Many factors contribute to peoples continuing
    desire to have children.
  • Religious opposition
  • Some people feel population sizes shouldnt be
    controlled
  • In some countries birth rate has fallen below the
    rate of replacement

7
Is Technology the Answer
  • Advances in technology have the potential to
    increase the resources available to humans.
  • New sources of renewable energy,
  • New strains of crops developed through genetic
    engineering
  • Other scientific breakthrough
  • The agricultural and industrial revolutions both
    increased Earths Carrying capacity
  • Future technology, such as increased use of solar
    power, may do it again.
