1 Challenges of Overpopulation
By: Keondra Holland and Traci Witcher! 12 slides – 4 flashcards

2 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.

4 Flashcard

5 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 people’s continuing desire to have children. Religious opposition Some people feel population sizes shouldn’t 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 Earth’s Carrying capacity Future technology, such as increased use of solar power, may do it again.
