Human Population vs.

Environmental Problems

As best as you can determine the connection between Human Population &

Environmental Problems.

Warm-up Feb. 8th Entry 12Use the picture to write a definition and draw a picture to represent the word BIODIVERSITY

Biodiversity

Variation in the different species

that live in an ecosystem.

Depends largely upon the

variation of plant life, which

depends on the amount of

precipitation.

Sustainability

Wise use of earth’s resources to

provide the best for people AND

the environment both NOW and in

the FUTURE

More people Bubble Chart

As a group make a bubble chart with ALL of the possible effects of a growing population will have on the environment and society as a whole

MORE people might mean….

Warm-up Feb. 8th Entry #12

Use the words birth or death to fill in the blanks

In order for populations to INCREASE the ______ rate must exceed the _____ rate.

When populations decrease the _____ rate exceeds the ____ rate. Which population is growing faster?

How do you know?

Let’s think about this………

MORE people might mean….

UNIT 3 HUMAN IMPACT

Help!!!!!

Human Population GrowthToo many people = environmental problems!

What caused human population growth? Causes:

Agricultural Revolution- more food to support more people

Industrial Revolution- improvements in technology, and medicine, increased birth rate and decreased death rate

Urbanization – development of cities, economic and social development

Human population Growth: J curve

Effects of Human Population Growth Overcrowding Increase in pollution-

ALL environmental problems relate back to human overpopulation!

Decrease of Natural Resources: More people require more resources

Increase land use

Solution:

Zero Population Growth: birth rate = death rate; china offers tax incentives for having one child; education, birth control

Conservation: wise and careful use of resources Reduce: use less materials Reuse: use products more than once Recycle: return products to be reprocessed

Sustainability – ensuring the availability of

resources and a stable environment for future

generations.

What’s in a Histogram? Ages, percent of males and females in the populationWhat can a histogram reveal? An increasing, stable or decreasing population

Public Service Announcement Assignment

OBJECTIVE: You will create a “Call to

Action” public service advertisement using iMovie to address the issues that increased human population size has had on a specific environmental problems in North Carolina and the world. This will be a SHORT video delivering the FACTS and the changes need to solve the problem.

GUIDING QUESTION: What impact does human population size have on the environment?

Did you answer /address these questions

Clear Introduction and important background information about the topic

How has the overpopulation of humans contributed to this environmental problem?

What are the short-term effects for the environment/ecosystems if nothing is done to change human behavior? (locally and globally)

What are the long-term effects for the environment/ecosystems if nothing is done to change human behavior? (locally and globally)

What should people do to help stop this problem?

Speak clearly and able to be easily understood

Within your group there should be at LEAST ONE article summary related to global issues , one article summary related to a LOCAL issue.

Cite your source on the index card. Write a summary (in YOUR OWN words) on your card explaining the MAIN ideas of the article. (How does overpopulation of humans relate to this environmental issue?) Tape or paste these cards onto your bubble chart.

Air pollution Land use Climate change Migration/Immigration Deforestation Public health

Social security

Energy

Waste management

Food resources/Hunger

Water resources

Housing and homelessness

Economics

Resource use/Consumption

Endangered species

RESEARCH news articles and opinion pieces on human population trends and related environmental and social issues. See the topics below. Each person should sign up for ONE topic to research.

Warm-up Feb. 11th Entry #13

Ozone depletion Caused by CFC’s -

(chlorofluorocarbons) destroy ozone layer –this increases UV radiation exposure –which increases skin cancer and crop damage; IS NOT RELATED TO GLOBAL WARMING!!!

Global warming too much CO2 in atmosphere increases average global temperature this could cause flooding, climate change, stronger storms, rising sea levels

Global Warming: unnatural warming of the Earth

Cause: Excessive greenhouse gases (carbon dioxide CO2 and methane CH4) in the atmosphere trap heat, leading to an abnormal increase in earth’s surface temperature CO2 comes from burning

fossil fuels CH4 from landfills and

cow farts!

Effect: It’s like the earth has a fever!Have you seen the movie “ The Day After Tomorrow”? increase in temperature (2-4 degrees

Celsius), weather patterns will change worldwide, polar ice caps may melt, flooding coastal cities and contaminating drinking water with saltwater.

Ozone Depletion: Has nothing to do with global warming!

Cause: CFCs (chlorofluorocarbons), once used as refrigerants and in aerosol cans destroy ozone molecules in the upper atmosphere leading to thinning or a hole UV radiation

is NOT heat!!!!

Ozone depletion :

Effects:Harmful UV radiation reaches earth causing increased numbers of sunburns, skin cancer, cataracts (leading to blindness), and crop damage.

Group Global Warming Activity Each group has a different topic describing one

effect of global warming. In your folder you have:

A copy of an article for each person to read Each person will answer the questions on a separate

sheet of paper in complete sentences… in your OWN words.

Each person will draw and complete the graphic organizer on their own paper.

Each group will creatively display the information from their graphic organizer in the educreation app (take a picture of the graphic organizer and each person explains a portion)

Each person is expected to speak/talk about their topic. Hi this is _________ and I am going to explain _______.

**implications means consequences Cindy.kendrick@cms.k12.nc.us password is : students

Interpreting the graphic organizer

Cause (what is the reason for the situation)

Event (what is happening as a result of the cause)

Effects (the result) Implications (consequences) Solutions (how can we fix this problem)

Ticket Out the Door

1. What three events allowed for the fast growth of human population?

2. What type of curve does human population growth look like when graphed?

3. Is the Country pictured in the Histogram a stable or developing country?

4. What is the cause of Global Warming?

Acid rain http://www.youtube.com/watch?

v=7xd_0t55mUY

Warm-up Feb. 12th Entry #14

Seven students argued about what they thought were the major human causes of global warming. Here is what each of them thought:: Maria: acid rain Natalie: burning coal Tessa: the fuel we use in our cars Anita: toxic chemicals in air pollution Raul: the thinning of Earth’s ozone layer Van: the growing landfills Blaine: the CFC’s from refrigerators

Write out the causes that you agree with. Explain why you agree.

Acid Rain

Cause: emissions (sulfur and nitrous oxides from cars and factories react with oxygen and water)

Blue ridge spruce and acid rain

Acid Rain:

Effects: A lowered

pH disrupts aquatic

ecosystems,

makes soil less

fertile, harms plant

life, and damages

human property.

Water Quality

Cause: sediments, oil, fertilizers from land, illegal dumping, acid rain, raw sewage, heated water from power plants

Effect: Disease, habitat destruction

Group Global Warming Activity Each group has a different topic describing one effect

of global warming. In your folder you have:

A copy of an article for each person to read Each person will answer the questions on a separate

sheet of paper in complete sentences… in your OWN words.

Each person will draw and complete the graphic organizer on their own paper.

Use an iPad to take a picture of a NEAT and filled out picture of the graphic organizer.

Each group will PRESENT their information/findings to the class. This means EVERY person will EXPLAIN a part of the graphic organizer. This does not mean you will be READING what is on the picture but EXPLAINING based on information from the article.

**implications means consequences

Biomagnification

Pesticides and TOXIC CHEMICALS “move up the food chain”

Chemical contaminants are stored (bioaccumulation)in the CELLS of living organisms (they do not get broken down.

TOXIC CHEMICALS are

magnified in organisms higher up the food chain because predators accumulate pesticides in the bodies of their prey. http://www.youtube.com/watch?v=E5P-

UoKLxlA

Biomagnification Demonstration Small beakers

represent ALGAE Medium beakers

represent FISH Large beakers

represent EAGLE

Draw a food chain and include arrows pointing to the consumers

Label the trophic levels

As pesticides are passed from one to the next. Write down the NUMBER of pesticides in EACH organism

Let’s use PAC-Man for our example..

The dots represent pesticides (toxic chemicals) in the environment

WHO gets more? Pac-Man or Pinky?

What is BIODIVERSITY??

Biodiversity Loss/ Habitat Destruction

Causes: Deforestation: cutting down

forests for wood, and farming

Draining/filling wetlands Bioaccumulation:

Greatest accumulation in lower organisms in the food chain

Biomagnification Magnified greatest in

organims higher in the food chain

Endangerment/extinction: Endangered species are at risk of becoming extinct. Extinction refers to the loss of a particular species. http://www.youtube.com/watch?v=E5P-UoKLxlA

Technology

Satellites: track changes global temperature and the ozone layer

Ice Core Analysis: Measure gases (CO2) that were once in atmosphere

Census Data: http://ozonewatch.gsfc.nasa.gov/Scripts/big_image.php?date=2012-12-29&hem=S

Census Data:

Developing Stable

Ticket out the Door

1.What is biomagnification?2. What is bioaccumulation?3. What organisms are most affected by biomagnification?

ADD BIOMAGNIFICATION (with a definition) to your bubble chart

Station rotation: Read article summaries and take notes Watch video about global warming and take

notes

Go back to your original BUBBLE chart and ADD information in a DIFFERENT color or by STARRING the info so that I know it was added. You should add 5 NEW things to your chart .

Ticket Out the Door 1.What three events

allowed for the fast growth of human population?

2. Use the histogram to determine if the population is increasing or decreasing. Explain how you know.

3.Explain how Global warming and Ozone depletion are NOT related. How are they different??

Warm-up

Environmental

Problems

Overpopulation – cause of all environmental problems

Global warming – too much CO2 in atmosphere increases average global temperature ->flooding, climate change

Ozone depletion – CFC’s destroy ozone layer -> increase UV radiation exposure -> increases cancer and crop damage
