1 Do Now: By now you are aware that the human population is still growing rapidly around the world. Can our planet handle this growth? Do we need to slow population growth? Can we? Explain your answer using data and examples to back it up!

2 Aim: How Can We Slow Human Population Growth? We can slow human population growth by reducing poverty, elevating the status of women, and encouraging family planning.

3 As Countries Develop, Their Populations Tend to Grow More Slowly Demographic transition – First death rates decline – Then birth rates decline Four stages 1. Preindustrial 2.Transitional 3.Industrial 4.Postindustrial

4 Fig. 6-17, p. 140 Four Stages of the Demographic Transition

5 Fig. 6-17, p. 140 Stage 1 Preindustrial Stage 2 Transitional Stage 3 Industrial Stage 4 Postindustrial Population grows very slowly because of a high birth rate (to compensate for high infant mortality) and a high death rate Population grows rapidly because birth rates are high and death rates drop because of improved food production and health Population growth slows as both birth and death rates drop because of improved Population growth levels off and then declines as birth rates equal and then fall below death rates 80 70 60 Total population 50 Birth rate 40 30 20 Death rate Birth rate and death rate (number per 1,000 per year) 10 0 LowIncreasingVery highDecreasingLowZeroNegative Growth rate over time food production, health, and education

10 Empowering Women Can Slow Population Growth Factors that decrease total fertility rates: – Education – Paying jobs – Ability to control fertility Women – Do most of the domestic work and child care – Provide unpaid health care – 2/3 of all work for 10% of world’s income – Discriminated against legally and culturally

11 Fig. 6-20, p. 141 Burkina Faso Women Hauling Fuelwood

12 Promote Family Planning Family planning in less-developed countries – Responsible for a 55% drop in TFRs – Financial benefits: money spent on family planning saves far more in health, education costs Two problems 1.42% pregnancies unplanned, 26% end with abortion 2.Many couples do not have access to family planning

13 Read A Loud Case Study: Slowing Population growth in India

14 Case Study: Slowing Population Growth in India 1.2 billion people, most populous country by2015 Problems – Poverty – Malnutrition – Environmental degradation Bias toward having male children Poor couples want many children Only 48% of couples use family planning

15 Do you understand how we can slow population growth?

16 Pause…Think…Write Based on population size and resource use per person is the U.S. more overpopulated than China or India? Explain giving support from the case study.

17 Movie Clip: Slowing human population growth in India

18 Summary Our numbers expand but Earth’s natural systems do not. Lester Brown

19 Three Big Ideas 1.The human population is increasing rapidly and may soon bump up against environmental limits. 2.Even if population growth were not a serious problem, the increasing use of resources per person is expanding the overall human ecological footprint and putting a strain on the earth’s resources.

20 Three Big Ideas 3.We can slow population growth by reducing poverty through economic development, elevating the status of women, and encouraging family planning.
