5.  Forest is an important source for satisfying people’s demands and
needs.
 Thus, undoubtedly people would try to exploit forest resource. This
process of exploiting forest is called DEFORESTATION.
 Deforestation is the process of clearing the forest by cutting down the
tress for fulfilling different demands.

6. What is Deforestation?What is Deforestation?
 The destruction of forests and trees.
 Has many harmful effects on the environment.
 Happening too quickly to recover.

10. Causes of DeforestationCauses of Deforestation
 Agriculture
 Logging
 Mining
 Dams

11. AgricultureAgriculture
 Leading cause of deforestation
 Farmers need land to grow crops and raise animals
 They remove forest land to make room for farms
 They use slash and burn to perform deforestation
 Slash and burn is cutting away and burning the forest

12. LoggingLogging
 Loggers cut down trees for their wood
 Logging is illegal in many areas, like National Parks
 The wood is used for many purposes, including paper production and as a
building material

13. MiningMining
 Miners search for materials like gold, copper, and
aluminum
 This clears the land, including the forest that occupies it
 Contaminates the ecosystem with runoff

14. DamsDams
 Generate hydroelectric energy
 Flood forests that are upstream
 Trees decay slowly when dams are built in
tropical waters, depriving the water of oxygen

15. RoadsRoads
 Building the roads themselves destroys trees in the way
 Provides access to a larger area of the forest for loggers,
miners, and farmers

17. Effects of DeforestationEffects of Deforestation
 Disrupts water cycle and carbon cycle
 Loss of biodiversity
 Soil Erosion
 Poor water quality
 Disrupts water cycle and carbon cycle
 Loss of biodiversity
 Soil Erosion
 Poor water quality

18. Water CycleWater Cycle
 If the trees are gone, there
will be less transpiration and
less water released into the
hydrologic cycle
 If the trees are gone, there
will be less transpiration and
less water released into the
hydrologic cycle

19. Carbon CycleCarbon Cycle
 If trees aren’t there, carbon
dioxide will accumulate and
contribute to the greenhouse
effect

dioxide will accumulate and
contribute to the greenhouse
effect

20. Loss of BiodiversityLoss of Biodiversity
 Rainforests contain over half of the world’s species
 Loss of trees -> loss of primary consumers -> loss of secondary consumers.
 When trees are removed, all rainforest life is affected

21. Soil ErosionSoil Erosion
 Soil erosion is when soil is removed by natural causes
 When trees are gone, their roots cannot hold the soil in
place
 Reduces soil’s capacity to hold water
 Makes agriculture difficult

22. Poor Water QualityPoor Water Quality
 Soil erosion lets dirt enter runoff, lowering water quality
 Makes for bad living conditions for fish
 A reduced amount of fish can cause ramifications all the way up the food
chain

24. AmazonAmazon
 World’s largest tropical rainforest
 Located in South America
 1/5 of the world’s plants and 1/10 of animals are found
here

25. Rainforests in AfricaRainforests in Africa
 World’s second largest rainforest
 Almost all of the forest on Madagascar is gone
 Madagascar too contains a large amount of
biodiversity that has been compromised

26. Rainforests in Southeast AsiaRainforests in Southeast Asia
 Indonesia is covered in rainforest
 Has been deforested just like the Amazon and in Africa
 It is hot and humid the whole year

Help?
How You Can
Help? Buying sustainably grown foods
 Buying environmentally friendly paper

29. Sustainably Grown FoodSustainably Grown Food
 This is food that was grown without negative effects like deforestation
 Only buying this type of food pressures businesses into producing it,
as they will produce what you buy

30. Environmentally Friendly PaperEnvironmentally Friendly Paper
 This could be recycled paper or paper made from bamboo
 Again, this pressures paper making companies into using
recycled paper and bamboo paper
