Warm-up

If you finished your quiz on Thursday...

• What are different ways that humans impact the planet?

If you did not finish your quiz on Thursday...

• ...then finish it (duh!)

Objective

• Analyze the relationship between consumerism, overpopulation, and the environment.

Unit notesSet up two pages in notebook as shown

below.Label one overpopulation and the other

consumerism.Description/Statistics Examples

Overpopulation

• What is it?• When the

population exceeds the amount of resources that are available.

• Critical thinking:• Is the world

overpopulated?

World Population

1. What is the graph showing?

2. What will the population be in 2050?

3. What factors have led to high population growth?

World Population Density

1. What is the graph showing?2. What regions have a high population density?3. What regions have a low population density?

Growth Rate

1. What is the graph showing?

2. What areas have high growth?

3. What areas have low growth?

4. How can this map be used to predict how the previous map will change in the future?

Consumerism

• What is it?• When natural

resources are used in excess of need

• Critical thinking:• What resources

do you “overconsume”?

Warm-up1. Why does the United States have the third largest population in the world but it is not considered overpopulated?

2. Why would it be easier for Africa to become overpopulated?

3. What are 3 countries that are responsible for consumerism?

Ecological Footprint

• Estimate consumption of resources• Ecological Footprint Calculator• Carbon Footprint Calculator• Water Footprint Calculator

Videos

Overpopulation

• Video• What is happening to the

time span between adding a billion people to the world population?

• What is a demographic transition?

• Why is the world population continuing to increase rapidly despite decreased growth rate

Consumerism

• Video• What is embodied energy?• How do Americans

compare to Indians in terms of energy usage?

• What are some of the problems with the “American” diet?

StatisticsConsumerism• Richest 20% consumes

86% of the resources

• Poorest 20% consumes 1.5% of the resources

• If everyone in the world lived like Americans, it would require the resources of 6 planet Earths to support society

• Graphs• From www.newscientist.com

• Tables• From United Nations

Overpopulation• World population

• 6,961,450,377

• 2012 = 7 billion• 2050 = 9.2 billion• World population

increases by 200,000 each day

• At 1% growth rate, a country’s population will double in 70 years

• By 2030, 4.9 billion people will live in large cities

Population pyramids

Can be used to predict future population growth

Fertility Rate(average number of children per woman)

DOL (Option A)• Write a short paragraph explaining how

population growth and use of resources impacts the environment

• Plan• Topic sentence• Describe overpopulation

• Impact on environment• Impact on environment

• Describe overconsumption• Impact on environment• Impact on environment

• Conclusion

DOL (Option B)

• List and describe 5 ways that overpopulation and consumerism impacts the environment.

Warm-up (Review)

• Make a Venn diagram (overlapping circles) • Compare and contrast overpopulation and

consumerism. • Place a minimum of 3 items in each

section of the diagram.

SampleVenn Diagram

Overpopulation and consumerism…

How do we fix it?

Essential Questions

1. What is China's One Child Policy?

2. What are the possible benefits of the policy?

3. What are the potential pitfalls of the policy?

4. What is your opinion of the policy?

Mini debate

• Opening statement (30 seconds)• Rebuttal 1 (30 seconds)• Rebuttal 2 (30 seconds)

Warm-up

Using your notes from yesterday, the article, and prior knowledge…

1. In your opinion, has China’s one-child policy been effective in reducing the negative impact of overpopulation? Explain.

2. Do you think that this policy should be implemented in all countries with a growth rate over 2%? Explain.

Solving the problem• Work with a partner and develop a solution

for overpopulation and a solution for consumerism.

• Your solutions should have the following characteristics:• Logical - reasonable; to be expected

• Realistic - based on what is real or practical

• Ethical - pertaining to right and wrong in conduct

• Affordable - believed to be within one's financial means

• Sustainable - able to be supported as with the basic necessities or sufficient funds

Evaluating Solutions

• Score 1 to 5 and explain reasoning.• What to look for:

• Logical - reasonable; to be expected

• Realistic - based on what is real or practical

• Ethical - pertaining to right and wrong in conduct

• Affordable - believed to be within one's financial means

• Sustainable - able to be supported as with the basic necessities or sufficient funds

Show what you knowDOL

• Score the following solutions to overpopulation and overconsumption on a scale of 1 to 5 and explain your reasoning. List the pros and cons of each.

1. American men and women are paid $50,000 by the federal government for waiting until the age of 30 to have children.

2. African women who do not have children by the age of 16 receive a free education and free apartment in a developed city such as Nairobi or Johannesburg.

Extension

• Carrying capacity is the maximum population that an environment can support.

• The world population is currently at 7 billion people.

• What do you think the carrying capacity of the Earth is for the human population? Explain.
