deforestation

• • Deforestation= the clearing of trees (usually large scale)
  • If trees r replaced by replanting = sustainable practise
  • Generally the trees r cleared for the land to be used in a different way (building, grazing for cattle, planting of monocultures eg palm oil plantations) -> NOT sustainable
  • Earth’s surface covered by trees decreases, it causes neg effects on enviro, example of habitat destruction
  • Undesirable effects include:

  1. Extinction of species
  2. Soil erosion
  3. Which leads to leaching
  4. Flooding
  5. Increase of carbon dioxide in the atmosphere
  6. Disturbance of water cycle
