  1. Populations Chapter 24 http://blue.census.gov/ipc/www/clock.html

  2. Human Population • We have seen factors that influence the growth of populations in general. • Next we will apply some of these to the human population.

  3. Fig. 24.22 Exponential growth in the human population

  4. G = r x N World Population: 2002 N = 6,228,394,430 r = 1.18 G = 73,915,261 http://www.census.gov/ipc/www/world.html

  5. Births - Deaths = r Changes in birthrates and death rates in Sri Lanka

  8. Examine the population demographics of these countries. • Sweden • Mexico • United States • Determine G, N and r • http://www.census.gov/ipc/www/idbsum.html

  9. Age structures of three nations Shrinking Growing Stable Are these growing, shrinking or stable populations?

  10. Your assignment • Create a single powerpoint slide containing • Data on your assigned variable for France, Tanzania and the United States (be sure to include units). • Explain the impact of curing heart disease and malaria on your variable – OR - • Explain the impact of population changes predicted for 2050 your variable. • The name of your group members. • Go to D2L and put them in the drop box.

  11. Pop. Pyramid http://www.census.gov/ipc/www/idbpyr.html N, r, and G http://www.census.gov/ipc/www/idbsum.html • Variable Predict • N, r, and G Impact of curing malaria and heart disease on variable • Life expectancy Impact of curing malaria and heart disease on variable • Kids/woman Impact of curing malaria and heart disease on variable • Infant Mortality Impact of curing malaria and heart disease on variable • Adult Mortality Impact of curing malaria and heart disease on variable • Immigration Emigration Impact of curing malaria and heart disease on variable • Ecological footprint Change of variable in 2050 vs. today • Water supply amt./quality Change of variable in 2050 vs. today • Population density Change of variable in 2050 vs. today • Land use Change of variable in 2050 vs. today • Wildness Change of variable in 2050 vs. today

  12. Heart Disease is the leading cause of death in developed countries. • 50% of all deaths in US and Europe, typically >50 years old. • Caused by obesity, poor diet, lack of exercise, diabetes, and genetic factors. Clot in Coronary Artery

  13. Malaria kills 2-3 million humans annually (90% of malaria deaths are in Subsaharan Africa) Caused by Plasmodium parasite and transmitted by mosquito Affects primarily children under age of five and pregnant women (Malaria kills an African child every 30 sec)

  14. Example: Life Expectancy for Tanzania, France, and United States Source: US Census Bureau By: I.M. Smart M.E. Too NOTE, THESE ARE NOT CORRECT ANSWERS, JUST EXAMPLES

  15. Next class period we will… • Present your slides in class and use them for discussion. • Discuss the impact of curing heart disease and malaria on some of these variables. • Discuss the impact of population changes predicted for 2050 on the other variables. • This is worth 5 points on the final exam.

  27. Fertility Rate Per WomanSource: US Census Bureau No impact for curing heart disease because the women are above childbearing age. No impact for curing malaria in the USA or France because they are developed countries. Increase in Tanzania because less children will be dying and pregnant women will have fewer complications.

  35. Ecological Footprint As the population increases over the next 45 years, the concentration of people per hectare will increase which results in a lower ecological footprint per capita.

  42. Land Use – percent of total land area available for: cultivated crops (arable land), permanent crops (Permanent), and other areas (Other) such as prairies, pastures, forests, and built-on lands. It is predicted that the population in Tanzania and the United States will almost double, while the growth rate of France is not nearly as high. Land Use By: Breann Sommer, Jens Hogberg, Lindsay Tietz, & James Bodah

  43. Wildness for Tanzania, France, and United States Tanzania will decrease because they are still a developing country. France will decrease slightly because they have used up most of their unprotected land. The USA will decrease because of our increasing population. Not all of the land will be used because the United States has one of the largest masses of preserved land. All of the countries will decrease in wildness because the world population has not reached its carrying capacity. By: Amy Yoel, Megan Brisch, Alison Smetana, Ethan Lor Source: www.nationmaster.com

  45. Examine the data you collected • For each variable, determine the impact of curing malaria and heart disease on that variable.

  46. In developed countries, what happens if we cure heart disease? • Population • Consumption • Quality of life No significant increase Increase Increases life expectancy, but will also increase heath costs and drain on resources

  47. In developing countries, what happens if we cure malaria? • Population • Consumption • Quality of life Significant increase Increase Increases life expectancy, but will also dramatically increase use of already scarce resources
