Paper 2: human impacts on environment

  • deforestation
    Deforestation is the process of clearing trees, usually on a large scale. This is often done to make way for building or agriculture.
  • environmental effects of deforestation?
    Environmental effects of deforestation include:
    • Extinction of species
    • Soil erosion
    • Leaching
    • Flooding
    • Disruption of the carbon cycle
    • Disruption of the water cycle
  • soil erosion 

    Soil erosion is the process by which soil is removed from its original location, e.g. by rainwater or wind.
  • deforestation impact on water cycle 

    Deforestation can disrupt the water cycle. The removal of trees reduces water vapour entering the atmosphere by transpiration, reducing cloud formation and therefore reducing rainfall.
  • deforestation impact on CO2 concentration

    Deforestation increases atmospheric carbon dioxide concentration. This is because living trees absorb carbon dioxide during photosynthesis; removal of these trees therefore reduces the rate at which carbon dioxide is removed from the atmosphere.
