  1. Homework • Due for Wednesday (today): 211 starting at Population and Society 218 stopping at HIV / AIDS is exerting… • Due 218 starting at HIV / AIDS is exerting… to the end of the chapter. We will spent a fair amount of time on HIV / AIDS • Next week’s vocab Words 46-50: Quiz will be Saturday! • 46. Manipulative Experiment • 47. Correlation Experiment / Study • 48. Fauna • 49. Dr. Salk • 50. R Species vs K Species

  2. Do now • What is the connection between the Destiny Africa group and the topics we are discussing? Hint, where was the group from and what is the greatest issue in that region? • Group is from Uganda • The area is ground zero for HIV / AIDS

  3. Quick Review • What is IPAT? • Impact = Population x Affluence x Technology, sometimes add S for sensitivity, meaning development in a sensitive area. • Strong nations tend to have slow population growth. Why? • Demography? What is it?

  4. Population distribution • Humans are unevenly distributed around the globe • Unpopulated areas tend to be environmentally sensitive (high S value in the IPAT equation) • Vulnerable to humans (e.g., deserts, arid grasslands)

  5. Age structure affects population size • Age structure diagrams (population pyramids) show age structure • Wide base = many young: • High reproduction • Rapid population growth • Even age distribution: • Remains stable • Births = deaths

  6. Age structures: Canada vs. Madagascar Madagascar’s age structure is heavily weighted toward the young Canada’s age structure is balanced

  7. New Material • Transition Demographics – explain the chart below

  8. Reading to focus on • Why did Fertility Decline in Bangladesh decline? • Education of women: • Better opportunities • Greater chance of not living in poverty • Longer lives • Educating women reduces fertility rates, delays childbirth, and gives them a voice in reproductive decisions

  9. Empowering women reduces growth rates • Fertility rates drop when women gain access to contraceptives, family planning programs, and educational opportunities • Women with little power have unintended pregnancies • Two-thirds of the world’s illiterate are women

  10. Correlation of poverty and population • Poverty exacerbates population growth • Population growth exacerbates poverty • In 1960, 70% of all people lived in developing nations • As of 2010, 82% live in these nations • 99% of the next billion will be born in these nations

  11. Poverty & environmental degradation • Population growth in poor nations increases environmental degradation • Farming degrades soil in arid areas (Africa, China) • Poor people cut forests, deplete biodiversity, and hunt endangered species (e.g., great apes) Africa’s Sahel and western China are turning to desert

  12. Question • In the industrialized world, what is the greatest cause of death? • Heart Disease – directly related to poor diets (obesity). • What about in the 3rd World? • AIDS, why? • Is AIDS really an issue in the United States?
