Deforestation


► Deforestation  is
  defined as the loss of
  forests that occurs
  when people cut down
  trees.
Why do people cut down trees?

Use wood for building

               ► Use   wood for fuel
Why do people cut down trees?
               ► Toclear land for
                farming
Why do people cut down trees?
► Small farms to feed
 families
   Often formed by “slash
    and burn”
     ► Slash   -Cut down the
       trees
     ► Burn the trees to clear
       the land for farming
   Generally cut down only
    small areas at a time
Why do people cut down trees?
                      ► Plantations
                         Clear large areas to
                          plant crops

Reasons for Deforestation




   What is the major cause of deforestation?
Amount of Deforestation Has
        Increased Over Time
► Why?
► Better   tools
   From stone axes to
    chainsaws
Amount of Deforestation Has
        Increased Over Time
► Why?
► More   People
   More people to feed
    means we need more
    and larger farms
   So people cut down
    more trees
Where is Most Deforestation
        Occurring?
Where is Most Deforestation
        Occurring?




 Which country has the highest rate of deforestation?
Where is Most Deforestation
               Occurring?
► Today,  most deforestation is occurring in tropical
  regions.
► Tropical rainforests are found in tropical
  rainforests
    Most deforestation in tropical rainforests
Results of Deforestation




► Clear   cutting- cutting down all trees in an area
Clear Cutting
► Loss   of all habitat for wildlife
   If animals have no place to live then it is
    possible that they will all die
► Habitat
        loss is the leading cause of species
 becoming extinct.
The number of birds in Brazil is
 predicted to decrease in the future as
the amount of deforestation increases.
Habitat Loss and Extinction




► Many species on the earth are at risk of
 extinction caused by deforestation
Clear Cutting
► Soil   erosion
    Without plant roots to
     hold the soil in place
     soil particles are easily
     eroded away by water
     when it rains.
    When soil is lost the
     soil is not as good for
     farming.
Clear Cutting
       ► Soil erosion causes
         siltation
           Eroded soil particles
            end up in rivers
                ► Rivers   become muddy
                     Harms the animals
                      and plants that live in
                      the river
           Rivers carry eroded
            particles into the
            ocean
                ► Siltcan damage coral
                  reefs
Deforestation in Malaysia
Deforestation in Malaysia




► Tropical Rainforests are found in Malaysia
► Rates of deforestation in Malaysia are some of the
  highest in the world
Deforestation in Malaysia
Logs are transported by floating
       them in the river

                ► These  logs can
                  sometimes escape to
                  the sea and damage
                  coral reefs when they
                  are washed ashore by
                  storms.
Reasons for Deforestation in
                Malaysia
► Trees   are cut in Malaysia for
     Lumber
     Fuel
     To clear land for agriculture
Oil Palm Plantations
Forest cut to plant oil palm
        plantation
Oil Palm
    ► Thefruits of oil palm
     are used to produce oil
       Used in cooking
       Used as fuel
           ► Palm oil can be added to
            gasoline and used to
            drive your car
               biofuel
Oil Palm Plantations in Malaysia
► Deforestation   to clear
  land for oil palm
  plantations
   Habitat loss
   Erosion
The amount of undisturbed forest
has been decreasing rapidly in the
    last sixty years in Borneo

                           map shaded in

                           undamaged
                           forest
Habitat Loss and Extinction in
          Malaysia
               ► The Four Most
                 Endagered Terrestrial
                 Species in Malaysia
                      Tiger
                      Asian rhinoceros
                      Asian elephant
                      Orangutan

               ► Allare at risk because
                 of habitat loss caused
                 by deforestation
Deforestation in West Texas?
► Today  we think of deforestation as being a
  problem that is occurring in the tropical
  regions.
► Do you think that deforestation has
  occurred in West Texas?
Deforestation in West Texas
► Sand   shinnery oak
   Quercus havardii

   Short (1 – 1.5 meters
    tall)
   Spread by underground
    branches
     ► Individuals   plants can be
         100m x 70m in size
         (that’s one of the largest
         individual plants in the
         world!!)
Deforestation in West Texas
              ►   Before the white settlers
                  reached the high plains, 5
                  – 7 million acres of sand
                  shinnery oak was spread
                  across the high plains of
                  New Mexico, Texas, and
                  Oklahoma
              ►   It was the largest oak
                  forest in area in the United
                  States
              ►   (About the size of the
                  state of Maryland)
Deforestation in West Texas
► Todaymost of the sand shinnery oak has
 been destroyed
   Removed by
    ►chopping down the trees and digging up the roots
    ►Poisoning with herbicide
        poisons that kill plants
Deforestation in West Texas
              ► Sand
                   shinnery oak was
               removed
                 To grow pasture
                   ► Cattle   don’t like to eat
                       the oak leaves so they
                       cut down the trees and
                       plant grass instead
                 To grow cotton
Deforestation in West Texas
► Deforestation
              has caused the loss of what
 once was the largest oak forest in the US!!

► Who knew that deforestation was important
 on the prairie in West Texas!!
Habitat loss has harmed some of the
 species that lived in the shin oak
               habitat

Deforestation
► Do   you
   Live in a house built with wood?
   Burn wood in your fireplace?
   Eat food grown on farms?
   Eat food or drink milk that comes from
    pastures?
   Ride in a car powered by gasoline?
Deforestation
► If you answered yes to any of these
  questions then you have probably benefited
  from the results of deforestation
Deforestation
► Are   you sad when
     Trees are cut?
     When species go extinct?
     The soil washes away?
     When rivers become full of silt?
     When fish die in silty rivers?
     When coral reefs are destroyed by silt
Deforestation
► Ifyou answered yes to any of these
  questions then you have probably been
  harmed by deforestation.
Is deforestation good or bad?
► This   is a complex question
     Deforestation both helps and harms us
     Different people have different opinions about
      this
       ►Who might favor deforestation?
       ►Who might be against deforestation?
