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?
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)
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
Age structures: Canada vs. Madagascar Madagascar’s age structure is heavily weighted toward the young Canada’s age structure is balanced
New Material • Transition Demographics – explain the chart below
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
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
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
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
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?
