Chapter 9Review and Recap

9.1– Studying Human PopulationsKey Questions:• Why would we study population in Environmental Science?• How do we study populations?• How and why has human population changed over time?• What factors do we consider when predicting future

population growth?• How do economic and social changes affect population

growth rates?

1:30-2:20

Key Questions:• What are the problems associated with population growth?• Are the proposed problems actually problems?• What solutions exist for such problems?• How effective are these proposed solutions?• How do population growth trends differ between developed and

developing countries?• What are the population projections for the next century?

• Discuss the following question as a class and write an answer on the board :

Why are we studying the human population?

1:30-2:20

•Discuss and Discover

We discussed all but the last two items on this timeline.Answer the following with a partner (5 min).• Why are these two items on the map?• What connection is there between population,

poverty, and a rise in urban living?1:30-2:20

• One more Timeline question:

1:30-2:20

• On your timeline worksheet, there are two more significant dates listed. Do some research as a class or search your brains and write/discuss why these dates are significant.

• Discuss the following question as a class and write an answer on the board :

How and why has human population changed over time?

1:30-2:20

• If time remains, share the results of your homework on CO2 Emissions vs. Population growth with a partner.

• After you have finished discussing (5 or so minutes), answer the following questions as a class:

1. Why was the Breathing Earth website created?

2. What kinds of things does it show?

3. Does it show a correlation between population and Carbon emissions? If so, what kind? Direct (as one increases the other increases) or Inverse (as one increases the other decreases)?

• Discussion Questions5. Do you think that simply changing birth rates will cause a nation to undergo further development?

Yes?No?

Why?

1:30-2:20

• Reflection Questions to Consider

• Read article about 1-child policy in China and write 1 page reflection answering the questions (you may write or type it): • Is/was it a good policy? • What are the economic ramifications of the policy? • What are the moral/emotional/psychological

ramifications of the policy?

You may conduct additional research online if you wish—Reflection is due Monday.

Solutions Pros Cons Absurd or Reasonable?

Example: Abortion- keep women from having the babies the conceive

Fewer people consuming resources, fewer unwanted children

Morally unacceptable (killing an innocent human being is always wrong)

? What do you think ?

Contraception

One-Child Policy

1:30-2:20

• Environmental Problems Satire• What issue or issues will you seek to solve?

• Of these issues, which are causes and which are effects? Or are they unrelated?

• Are there any solutions to these issues that would seem logical and fitting at first but would lead to disastrous ends?

• Is there anything that we are already doing to solve this problem that could get out of hand and become absurd if it continues along the same path?
