      Deforestation in the tropical rainforest

      Lesson details

      Learning outcome

      I can explain the causes and changing rates of deforestation.

      Key learning points

      1. Tropical rainforests are threatened by deforestation.
      2. Rates of deforestation are changing.
      3. There are several causes of deforestation, such as commercial logging, agriculture and mineral resources.

      Keywords

      • Deforestation - large-scale removal or clearing of forests

      • Biodiversity - a measure of how many different species live in an ecosystem

      • Subsistence farmers - farmers that grow only enough food for themselves

      Common misconception

      Deforestation is primarily caused by small-scale farmers cutting down forests for subsistence farming.

      Deforestation is driven by large-scale commercial activities, such as industrial agriculture (like palm oil and soy), logging, and cattle ranching, which are often linked to global demand.

      Teacher tip

      The GIS lesson in this unit, 'Using GIS to visualise and analyse deforestation', gives pupils the opportunity to use GIS tools to engage with causes and impacts of deforestation.

      6 Questions

      Q1.
      Where are tropical rainforests located?

      north of the Tropic of Cancer
      south of the Tropic of Capricorn
      Correct answer: south of the Tropic of Cancer
      Correct answer: north of the Tropic of Capricorn

      Q2.
      Why are ecosystems important?

      they are all the same
      they exist only in rainforests
      Correct answer: they support a variety of life forms

      Q3.
      What is the climate like in a tropical rainforest?

      Correct answer: wet, with over 2000 mm of rainfall per year
      dry, with under 250 mm of rainfall per year
      Correct answer: warm, with an average daily temperature of 28°C
      cold, with an average temperature of 10°C

      Q4.
      Order the layers of the rainforest from the highest above ground to the lowest.

      1 - emergents
      2 - canopy
      3 - under canopy
      4 - shrub layer
      5 - ground level

      Q5.
      What is deforestation?

      large-scale planting of forest
      Correct answer: large-scale removal of forest
      working with the forest to meet human needs

      Q6.
      Tropical rainforests are hotspots as they are home to over 50% of the world’s plant and animal species.

      Correct Answer: biodiversity

      4 Questions

      Q1.
      Globally, tropical rainforests are threatened by .

      Correct Answer: deforestation

      Q2.
      Tropical rainforests are __________ hotspots as they are home to over 50% of the world’s plant and animal species.

      urbanisation
      Correct answer: biodiversity
      globalisation

      Q3.
      How is deforestation linked to climate change?

      1 - Rainforest plants remove carbon dioxide from the atmosphere.
      2 - Trees store masses of carbon for years: this reduces the greenhouse effect.
      3 - Deforestation reduces the amount of carbon taken by trees from the atmosphere.
      4 - Burning felled trees/letting them rot adds stored carbon back to the atmosphere.

      Q4.
      What kind of farming is used by subsistence farmers?

      cattle ranching
      Correct answer: slash-and-burn
      organic
