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

• 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.
