Where Have All the Trees Gone?

• A Lesson on Recycling
• (with some math thrown in!)

3
Maybe if we didnt use so much paper for
homework, we wouldnt kill so many trees!
Mrs. E, why are these pictures of the forest
empty? There are no more trees in the forest.
What happened?
4

• Well, let me explain what is happening.
• First of all, the population of the world is
  increasing, which means more people are using
  more natural resources.
• Secondly, as we use these natural resources, we
  are not replenishing them, like in the case of
  the forest. We are not replanting the trees that
  have been cut down. We also are not conserving
  our resources. Many people think that these
  resources are infinite.but we know theyre
  not!!!
• So what can we do?
• How can we stop this abuse of our natural
  resources?

Lets Learn How We Can Help
Click on the following link to visit Recycle
City. Here you will find a lot of information
about how and what you can recycle. Let the
learning begin http//www.epa.gov/recyclecity/ma
inmap.htm

• Now that you have learned a lot about recycling,
  you should be able to answer the following
  questions.
• What does reduce mean? Define and give an example
  of how you can reduce the use of our natural
  resources in your home.
• What does reuse mean? Define and give an example
  of how you can reuse something to reduce the
  amount of trash you make.
• What does recycle mean? Define and give an
  example of at least 2 items that you can recycle
  and how this will help the environment.

• Lets see how many pounds of waste materials we
  recycle each year.
• Using the following statistics, determine the
  amount of waste material recycled every year.
  These are not actual statistics. For actual
  amounts, please visit the following website
  http//www.epa.gov/epaoswer/non-hw/muncpl/index.ht

• Americans use approximately 235,000 lbs. of paper
  each month. If 52 of this paper is recycled, how
  much paper still winds up in a landfill?
• Some drink manufacturers produce approximately
  198,325 lbs. of plastic each month to make soft
  drink bottles. If 31 of this plastic is
  recycled, how much still winds up in a landfill?
• Aluminum cans are not as popular as plastic
  bottles because they cannot be closed inbetween
  sips. Manufacturers, however, do turn 89,500 lbs.
  of aluminum into cans for drinks. If 45 of this
  aluminum is recycled, how much is dumped into the
  landfill?
• We all use refrigerators, washing machines,
  stoves, etc. But due to their size, it is very
  important that these appliances are recycled,
  because if theyre not, it will produce 415,600
  lbs. of waste in our landfills. If 67 of this
  material is recycled, how much will still be
  added to our landfills?

9
Okay, now that you have determined how much waste
material is dumped into our landfill each month,
lets view this data graphically. Using Microsoft
Excel, you are to choose either a line graph, bar
graph or pictograph to display your data. You may
visit the following website to review how to
create a graph in excel. http//www.internet4class
rooms.com/excel_create_chart.htm

10
Now lets learn about the different recycling
categories. Please visit the following website to
see how many different ways materials are
classified. http//www.oregon.gov/ENERGY/CONS/RCM/
docs/RecyclingCategories.doc

• Your next task is to classify items you recycle
  at home into the appropriate categories.
• First, list at least 20 different items that you
  can find in your home that can be recycled.
• Next, using Inspiration, create a chart showing
  how you will classify each of these items. Each
  column on the chart must list the recycling
  category. An example of a classification chart is
  shown below but remember, you are classifying
  recyclables, not animals.

Recycling is not an adult job. Children can make
a difference too! Your final task is to write a
letter to the mayor of Perth Amboy. As a student
in the Perth Amboy school system, you are well
aware of the fact that we do not have a recycling
program in our schools. You are to write a
friendly letter to Mayor Vas to convince him to
implement a recycling program in our schools and
to donate the money made from recycling back to
the school district to purchase necessary
supplies and equipment. Visit either of the
following websites to review how to write a
friendly letter. http//jc-schools.net/write/frien

Im gonna start by not doing my homework. Thatll
