Title: Lesson 9 - The Cost of Ignoring Economics and Geography


1
Lesson 9 - The Cost of Ignoring Economics and
Geography
  • The impact of geography and economics on the
    environment.

2
The Cost of Ignoring Economics and Geography
  • Is it a good idea to breathe gases from the
    tailpipe of a car?
  • Gases and emissions from cars, factories, and
    other industrial sources can cause pollution and
    health problems in many large cities.

3
The Cost of Ignoring Economics and Geography
  • What natural forces can help reduce the effects
    of pollution in the air?

4
The Cost of Ignoring Economics and Geography
  • What are some other sources of pollution and
    waste that people put into the environment?

5
The Cost of Ignoring Economics and Geography
  • Waste is often put into our rivers, in part
    because water is another way to wash and diffuse
    waste. Much like the motion of the air by winds,
    the motion of water diffuses and dilutes waste so
    it is less concentrated. These physical processes
    of degradation or decomposition are the result of
    bacteria in the water that break waste down into
    less-harmful substances. As waste moves down a
    river, these processes reduce the impact of the
    waste on the surrounding environment.

6
The Cost of Ignoring Economics and Geography
  • How can we best control the amount of waste that
    is being released into the environment?
  • What are the issues we must consider when making
    our decisions?
  • Natural Processes
  • Costs

7
The Cost of Ignoring Economics and Geography
  • Dilution As waste flows further and further
    downstream, the water dilutes the waste so that
    it has a smaller impact on the environment.
  • Decomposition Organic waste will decompose over
    time and will have a smaller impact on the
    environment as it decomposes.

8
The Cost of Ignoring Economics and Geography
  • Flow Map
  • Points 1, 2, 3, and 4 are each 10 miles apart.
  • The river flows downstream toward Kleenville.
  • Each company uses the river to dispose of waste
    created during production.

9
The Cost of Ignoring Economics and Geography
  • Each company currently releases 8 units of waste
    into the river during production.
  • As waste flows downstream, it is diluted or
    decomposed by half every 10 miles.
  • How much waste reaches Kleenville from Acme?
  • 8 units (at the factory) 4 units (at point 2)
    2 units (at point 3) 1 unit (at point 4) 1
    unit reaches Kleenville.

10
The Cost of Ignoring Economics and Geography
  • How much waste reaches Kleenville from all the
    factories along the river if each releases 8
    units into the river?

11
The Cost of Ignoring Economics and Geography
  • The residents of Kleenville want to reduce the
    amount of pollution reaching their town by half
    because their river is smelly and the pollution
    could cause health problems for people who use
    water from the river to bathe, cook, drink, and
    swim.

12
The Cost of Ignoring Economics and Geography
  • How can the companies achieve this goal?
  • Would all of the options cost the companies the
    same amount?

The Cost of Ignoring Economics and Geography
  • How much would it cost for Acme to reduce its
    pollution to 4 units of waste?
  • 1 (1st Unit) 2 (2nd Unit) 3 (3rd Unit)
    4 (4th Unit) 10 to reduce waste to 4 units.
  • How much would it cost for each company to reduce
    its pollution to 4 units of waste?

15
The Cost of Ignoring Economics and Geography
  • What are some other options for reducing the
    total pollution reaching Kleenville to 5 Units?
  • What is the least costly combination of units of
    waste from each company to achieve the goal of 5
    units of pollution reaching Kleenville?

16
The Cost of Ignoring Economics and Geography
  • Why does the location where waste enters a river
    influence the impact of the waste downstream?
  • Appleville City Council is concerned about waste
    in the river, much of which comes from companies
    upstream from Appleville. What economic and
    geographic factors should the council members
    think about as they decide how much to clean up
    the waste in the river?

17
The Cost of Ignoring Economics and Geography
  • Can you think of any situation here in Oklahoma
    where there is pollution in a river that is
    similar to the pollution situation in Kleenville?

18
The Cost of Ignoring Economics and Geography
  • Oklahoma is currently negotiating with Arkansas
    to reduce the amount of phosphorous being
    released into the Illinois River and Oklahoma
    rivers and streams.
  • The phosphorous comes from the waste products
    from large poultry farms in northwest Arkansas.

19
Review Questions
  • Describe the situation with the Illinois River in
    your own words.
  • What do you think should be done about the
    pollution of the Illinois River?
  • Will dilution and decomposition take care of the
    problem without further action?

20
Review Questions
  • Which parties will be the most impacted by
    your solution?
  • What are the potential costs and benefits of your
    solution to the problem?
  • Do the benefits outweigh the costs?
