Lorax Reflection

Throughout the video, you were presented with animated 'evidence' that you can use to answer the following questions.


What has happened to the biodiversity over the course of the video?

How does supply and demand affect the economics of this story?

What is the environmental impact on air, water, and land in the video?

What is the balance between need and want in this story?

Does this illustrate the Tragedy of the Commons, NIMBY, or both?

Why is the Lorax so unsuccessful at convincing people to change their economics?  Is there something that could have been done differently?

Can you think of examples in Iowa that illustrate this event happening?

This 'fable' has been praised as having an environmental wake-up call, as well as being a 'gloom-and-doom' scenario of environmental disaster.   Give three points that support each side of the argument.

Klamoth Basin Crisis


In this case study, students examine global water shortage problems in the context of the current Klamath Basin water crisis. Two main perspectives are addressed, agriculture and the environment, along with multiple other perspectives including Native Americans, hydroelectric dams, and the fishing industry. Students learn about and discuss competing interests for water and analyze and critique scientific data, maps, and graphs.


Important Note: Native Americans are considered sovereign citizens of BOTH their own tribe and the United States. So, negotiating with Native Americans means that they have the same rights and respect due to them (according to the Federal Code), as negotiating with a country like Great Britain or Saudi Arabia.


The Case to Consider


Power point overview


YOUR TASK Come up with a compromise that you feel deals with all the issues in a fair and equitable manner. Detail this viewpoint using Web 2.0 product and accompanying narrative, or a colored presentation with pertinent points. Your presentation must include a pie chart that divides the water available.


You must deal with:


  • fresh water shortages
  • the purpose of a wildlife refuge
  • Native American rights
  • fishing rights, including harvest, spawning, and various methods of capture
  • hydroelectric dams and their purposes
  • community needs
  • agricultural irrigation needs

Grading will be done using the rubric below.   Group size is a MAXIMUM of 2, individuals may work alone.

Your Carbon Footprint


You sit down to a lovely dinner featuring Fareway protein (chicken from North Carolina or beef from Texas), Idaho potatoes, green grapes (from Chile), green beans frozen from the last farmer's market, and bread and butter from Kwik Star (shipped in from Wisconsin). What is the carbon footprint of this meal?

Well, first we need to figure out what a carbon footprint is. Wikipedia can help. http://en.wikipedia.org/wiki/Carbon_footprint

You have 10 minutes to develop your logic.


Part 2:  Watch the video








    Questions for Reflection
  1. Do you really think it matters that America eats food with a large carbon footprint? Remember, the KCRG guys said yesterday that we all change the environment, but that a large group of people change it more than a small group of people.
  2. Would you be willing to can or freeze your food?
  3. Would you be willing to avoid buying fresh fruit that traveled outside the bounds of the US?
  4. Grocery prices are most affected by what factors: wages, packaging,or shipping costs?
  5. Farmers markets have become popular with a slogan of "buy fresh, buy local". Do you shop at these? Why or why not?
  6. Sometimes we can decrease our meal cost by substituting ONE item. Which would you pick in this meal?

Avoiding the Tragedy of the Commons with Your Own Population Plan

Today, you will pick a partner and you will work together. You need to pick a country from North America, South America, Africa, and Asia.

Write your country names on the board under your groups. Once you pick a country, no one else can have it. NO ONE MAY PICK THE US, INDIA, OR CHINA.

Enter the basic data you find at the Information Please Almanac or the CIA Factbook at this shared data sheet

Eight pillars for population stability (from your book)

  • family planning
  • health care
  • national population rules
  • improve the lives of women
  • educate the population
  • help men become better parents and should responsibility for birth control
  • stop consuming so many resources

Now, using the data gathered yesterday and the eight pillars of controlling population, think about the four countries you have. These four countries will need to have the same decisions made for each of them, and they may need to transfer resources or people from one country to another.

How will you:

  1. make certain that there is access to clean water
  2. everyone gets fed adequately
  3. there are enough workers to take care of the old
  4. there are enough workers that are skilled in the jobs available in society
  5. raise the longevity expectation
  6. lower the infant mortality
  7. make sure people are motivated to work
  8. keep political stability
  9. allow the resources to be used
  10. keep the religious groups and community values intact
  11. the populations of the four regions stay stable
You must create at least 3 artifacts and a presentation for others in the class.  This is due tomorrow at the end of class.   (artifacts include diagrams, a list of legislative rules, color-coded charts, etc.)

FIRST 20 MINUTES:   Finish the video



SECOND 40 MINUTES:    Read the case study on deer management.
Decide which of the role players in the scenario is the most reasonable, and detail why you believe this to be so.   Pick an area of the country where deer are plentiful (no more than 1/4 of a state) , and then another where deer are not plentiful.    Think about the biome that is represented by these two settings.

Use the 4 study questions found in the case study to help think about how you will manage deer herds in these two settings. (kill 'em, introduce tertiary predators, stop hunting, sterilize them, or a million other things.)   Create a comparison poster or digital artifact that shows me your understanding of the deer's role as a consumer, the links it has to the food web, and how the tragedy of the commons can be dealt with.

LAST 20 MINUTES:   Explain how aging the deer population can impact how we understand the dynamics of deer in a location by trying to understand the resources found here

Is the Tragedy of the Commons Avoidable.

First 20 minutes

A later paper is in the front chalk tray; called "Revisiting the Tragedy of the Commons".   Please read it.  As you do so, we need to ask ourselves if the three observations, or assumptions, at the beginning of the chapter are true.   If we could set these up, perhaps we could avoid a tragedy of the commons.


1) How likely is it that we can develop a series of judgments and values for the world that can be mutally agreed upon?


2) How do we communicate the judgments and values to the whole of humanity?


3) Who administers and corrects when the judgments and values are in disarray?


Think carefully about these statements.   You'll be using the opinions and answers to these questions on Friday.

3. Why focus on U.S. population dynamics in particular?
4. Why is there disagreement about the carrying capacity of the Earth?
5. What assumptions are used to determine sustainability?
6. How does an increasing global market influence sustainability of the planet?

Garden Reflection or Mind Map

So you have planned your garden, planted the seeds, and got ready to reap the harvest.
Then, the bugs came. The rains fell, or didn't. The soil varied depending on the location of your garden.

How would an unchecked population explosion affect your species diversity?

Rank each of your plants as needing a lot, a moderate, or a little water. To do this, think of the final product. Really juicy fruits or veggies need much more water than fibrous or grassy counterparts.

Would you prefer an organic or non-organic means to control your bug or weed population? Explain why.

Based on the size of the garden you planted (remember, you had a 60 x 80 foot area available), what strategies would use for weed control?

How much food do you anticipate raising? Estimate the number of people it would feed.

Would preserving the food using canning or freezing or drying be an attractive choice for you and your family? Why or why not?
===========

In this unit, we talked about water, agriculture, and the atmosphere. How do the concept maps shown in the original handout affect your garden? For each of these categories, you must provide at least five specific connections to your garden.
===========

For each of the subcategories, there were misconceptions listed. A misconception is a common idea that is WRONG, but widely accepted. Examine the misconceptions in your handout. At least one misconception from each category can be connected to your garden. Explain how.

Spring is in the Air, and the Gardens are coming



To start with, you'll need to head over to PlanGarden and get an account. You and another person need to create a MEDIUM size or larger garden with a diversity that includes at least 15 species of vegetables and 5 types of herbs. You must effectively utilize the space in your garden, but also remember that aesthetics is a value that is appreciated in the environment.

CHOOSE TO SHARE YOUR GARDEN. Only 2 people per project.

Dimensions of the garden: 60 x 80 You must plant at least one 60 foot row of each and make a digital or scaled drawing.

Make a table of the species you are planting:

Species | Plant Spacing | Seeds or Plants?| # of Plants | Days to Harvest


Now, layout your garden. Use companion species as needed or desired.

Take Home TEST (40 pts)

This activity is a one to two page paper, emailed to marciarpowellATgmailDOTcom by Wednesday, 2/23. Margins must be one inch, double-spaced, with a 10 or 12 point font.

You must also turn in the two highlighted articles that we used on Wednesday through Friday, 2/16-2/18


Based on the five pillars of sustainability, is there a way to grow bananas that is a social good (that is, it has limited toxicity, positive economic benefits, and avoids poverty traps)? You may structure the banana farm any way you wish--as a coop, a banana republic, a subsistence locale, or a small business with less than 20 workers.

Your answer should demonstrate a knowledge of the terms found in this unit. You opinion should be clear. Evidence from the articles on bananas should be quoted in " " One or two graphics to show me complicated concepts may be used.

GRADING RUBRIC

Opinion (0 to 8 points) Your opinion that bananas may or may not be grown sustainably is supported with at least three pieces of evidence from the reading.

Social Good (0 to 6 points) Whether growing bananas can be termed a social good or not will be considered, based on evidence presented.

Toxicity and Business Structure (0 to 6 points) What type of business structure is best for the worker, and how does that affect the toxicity to which the worker is exposed?

Economic Understanding (0 to 8 points) Each economic term used correctly will be considered for 1 point, to a maximum of 8 points.

Sustainability (0 to 6 points) Each pillar of sustainability identified will be considered for 2 points, to a maximum of six points.

Grammar (0 to 6 points) Grammatical structure, including an introduction, a conclusion, and complete sentences will be considered for a maximum of six points.

Toxicity Factors

Imagine you are detasseling and a toxic cloud is dumped upon you by a crop-duster who didn't realize you were there. Or you get sprayed by Roundup because the wind is variable and you are doing spray work on an open tractor in the field? What's an acceptable level of chemical risk? That's the question that you need to consider as we do the activity on Wednesday. Here are the concerns:

Human health and toxicity
  • · acute effects: symptoms that appear within 24 hours
  • · chronic effects: long-lasting symptoms as a result of exposure
  • · epidemiology: how diseases are controlled and transmitted from one individual to another
  • · transmissible disease: something that is contagious
  • · risk analysis: process of defining and identifying potential problems
  • · risk assessment: a step in risk management that tries to figure the probability of an event happening and the resulting
  • · risk management: the entire process of assessment and analysis






We will be studying the case of Ecotourism found here and here

Water Purification

You will be given a sample of water that needs purified for drinking on Tuesday.  This water must be cleaned using at least a 5 step process, and then presented to me in a clean pop bottle that is 20 oz in size.

You must bring your own materials for filtering....they will not be supplied, but are easily available at Walmart or other locations in Manchester.
==Create a poster that explains your process.

List at least 3 resources.

Groups are individual or groups of TWO.   Did you notice the size?  TWO.

==Questions to think about:

1.  How long per day would people need to devote to purification?   How would this compare to your own life?
2.  When should mechanical straining be done?  Why?
3.  After adding iodine or chlorine products, the water should stand for at least 30 minutes before drinking.   Why?
4.  What would the temperature of the water have on the effectiveness of the treatment in killing microorganisms?
5.  In our own culture, we often desire infusions of plant matter (spices, teas, coffees).   Why is this not the case for the water we were purifying?
6.  Finally, do you think a treatment  lagoon or septic system with a leach field, like those found here Iowa, will affect water quality in a positive, neutral, or negative way.  Explain your reasoning.

You can do this!

Social Good---How Individuals can change the world




Social Good is when people do something to help other people solve their OWN problems. So, rather than giving people bottled water, you give them a pump so they can pump their own water, and you train someone in the community on how to fix the pump. Or you give someone a chlorinator, or teach them basic hygiene.

There are dozens of organizations devoted to producing clean water across the world.


But social good is more than a local effort. It also involves influencing people with political or economic power. Dolphin-safe tuna boycotts or fur-protests can change society. How do you do that?


You need to pick an issue of global importance to a subsistence family in a specific country and determine HOW you can develop a movement on a global front. Problems may include food security, access to medicine, access to child vaccines, access to health care, education, increased shelter (not water).

How do you:
develop a plan?
develop a relationship with the people who need help?
answer critics?

Who is providing:

the repair?
the training?
How do you deal with:
limited technology
hostile government?
funding?

Finally, remember that these people are poor--not stupid. They want a hand up, not a hand-out.

The Banana Problem



Apply the concepts from the basic economics lab of yesterday to the issue of bananas in the supermarket.  What does this mean?  It means you will learn about banana production, and then use each one of the words in the blog post below and apply it to the cultivation, harvest, sale, distribution, or environmental programs associated with bananas.  Here are 5 links to help you:

Basic Economics

You are helping a young middle schooler understand the basics of economics through a series of hands-on examples while you babysit and fix him/her lunch.   The materials you have available to you are a bag of mini-mms (in individual packages), paper plates, glass plates, a four cup pan, 2 mugs, silverware, 100 poker chips, a television, six packages of Easy Mac, eight bottles of water, one can of pop, dish soap, a towel, a marker, and two apples, a head of lettuce, and three dozen homemade chocolate chip cookies.  If you want, s/he may invite a friend to lunch.  The water in the house is off and the microwave is broken (but the stove works).


Your story can take the form of a series of cartoons, a mind-map, drawings, or a creative story.  No more than three people per group, please.  You will present this understanding to the class on Wednesday.

How do you explain:

  • economic good
  • economic need
  • economic want
  • market demand
  • basic nutrition
  • malnutrition
  • clean water
  • hunger
  • scarce resources
  • economic resource 
  • factor of production 
  • GDP (gross domestic product), 
  • non-renewable resource
  • internal costs
  • external benefits
  • external costs 
  • cost benefit analysis
  • pollution
  • recycling
  • social good
  • unemployment
  • employment

The Poverty Trap

Your goal:  To create your own idea of what a poverty trap is.

To start, read http://www.theglobalist.com/storyid.aspx?StoryId=5032  Each one of these poverty traps needs to be converted into a visual  flow chart.   Here's an example of one:


Now, in environmental science, we need to look at the world as a whole in terms of sustainability.   If individuals matter, we need to look at natural capital, solutions, tradeoffs, degradation and still consider the fact that individuals matter.   As such, we have to develop ways out of the poverty trap that are sustainable.

Use your pictures and see how they connect with this bigger picture of poverty by adding them on around this image (which is provided for you).   You will need to take a careful look at this to see the picture.

Write an essay response (3-6 paragraphs) on ways to dismantle poverty traps and post to your wiggio drop box for your group.

Inertia, Persistence and Resilience

(According to Wikipedia)


Resistance and inertia (persistence)

Resistance and inertia deal with a system's inherent response to some perturbation.
A perturbation is any externally imposed change in conditions, usually happening in a short time period. Resistance is a measure of how little the variable of interest changes in response to external pressures. Inertia (or persistence) implies that the living system is able to resist external fluctuations. In the context of changing ecosystems in post-glacial North America, E.C. Pielou remarked at the outset of her overview,
"It obviously takes considerable time for mature vegetation to become established on newly exposed ice scoured rocks or glacial till...it also takes considerable time for whole ecosystems to change, with their numerous interdependent plant species, the habitats these create, and the animals that live in the habitats. Therefore, climatically caused fluctuations in ecological communities are a damped, smoothed-out version of the climatic fluctuations that cause them."[3]

[edit]Resilience, elasticity and amplitude

Resilience is the tendency of a system to return to a previous state after a perturbation. Elasticity and amplitude are measures of resilience. Elasticity is the speed with which a system returns. Amplitude is a measure of how far a system can be moved from the previous state and still return. Ecology borrows the idea of neighborhood stability and a domain of attraction from dynamical systems theory.

Laws of Thermodynamics and it's relationship to population


http://mindbites.com/lesson/3969-biology-bioenergetics-the-laws-of-thermodynamics


Birth Rate, Death Rate, and Fertililty Rate

Calculation

1) Globally: Crude BR= 22, crude DR = 9. r = ?

2) More Developed countries (MDCs) crude BR = 11, crude DR = 10. r = ?

3) LDCs: crude BR = 25 crude DR = 9. r = ?

4) Determine the population change in a country which begins a year with 1 million people, has 1675 births, 450 deaths, 325 immigrants, 150 emigrants: N(1) =

5) Globally, over past 100 years, which has dropped more dramatically? BR or DR? Give three reasons why.

Words to Understand for Tuesday

As we take a look at these ideas of biomes and food webs, other vocabulary comes together. We need to look at this vocabulary in terms of the areas that we are studying.

For each of these, look at the link, and try to come up with a definition of your own. This WILL be handed in.

Law of tolerance

Range of tolerance

Energy flow

Limiting factor

Ecosystem

Terrestrial ecosystem

Aquatic ecosystem

Carrying Capacity

Niche

Biomes in Depth

Watch the video found here

OR

look at the site found here

OR

check out the information found on biomes in the previous post.

Compare a biome found in the continental US to a biome NOT found in the continental US. Make a poster or t-chart that lists similarities and differences in terms of temperature extremes (how hot and how cold), precipitation amounts, types of precipitation, and winds.

For each biome, find a relevant ecosystem and draw a food web with at least 12 pieces. You must include all components of an energy pyramid .

Based on this idea, what biome is richer in biodiversity? Why do you believe so? Can you suggest a calculation that estimates your point-of-view?

Energy Pyramids



These two pyramids are similar, but different.  What happens to the energy conversion rate as we move from a lower trophic level to an upper trophic level?

What implications does this have for an ecosystem if a disease hits a) the secondary consumer or b) one of the primary producers?   Speak in terms of diversity, please.

Unit 2: Activity 1



When a habitat is very diverse with a variety of different species, it is much healthier and more stable. One of the reasons for this is that disease doesn't spread as easily in a diverse community. If one species gets a disease, others of its kind are far enough away (due to the variety of other organisms) that disease is often stopped at the one or two individuals.




Based on this table, excerpted from http://www.accessexcellence.org/AE/ATG/data/released/0534-KathyParis/index.php, What is diversity and how is it figured?

Cape Wind: The challenge



Cape Wind is an offshore wind project that is proposed off of Nantucket Sound
It is also a NIMBY issues


Link 1


Pick a Person:

a) barista, making $20000/year
b) fisher, making $50000/year
c) homeowner, Wampanoag tribe member, and food stand operator, making $30,000/year
d) homeowner who uses the place as a second home
e) construction worker, making $70000/year
f) environmentalist, making $25000/year
g) energy executive, making $2,000,000/year


Pick a location

a) on the Sound
b) within 1/2 mile of the Sound
c) in an apartment
d) within 5 miles of the Sound

Pick a health issue

a) none
b) epilepsy

Pick an ethics viewpoint

a) sustainability for the world!
b) sustainability if it doesn't cost me money!
c) my way or the highway!
d) protect the animals!

Outline your profile on a sheet of paper. Each person in your group must have a different profile.

Do some research to come up with the rationale for why this might be a NIMBY project.


List 10 pros and 10 cons of the project.

Day 2


Have a discussion from the point of view of your profile. Use the pros and cons to discuss your ideas with another table.

Based on your profile, write a one page summary to explain your view for whether the project should go forward. These reasons for a pro or con choice must be supported by the evidence you gather (that is, does the evidence (not just the opinion) match your viewpoint. This is hard, because feelings don't sway a judicial decision--evidence does. Evidence usually takes the form of numerical data, financial impact, or the more nebulous 'cultural significance'



Each person will be individually graded. You may hand-write these or submit them in the drop box at wiggio.com
