    • Deforestation & Water Pollution
    • It is the permanent destruction of forests and woodlands for various purposes (eg. farming activies, setting up factories etc) What is Deforestation?
      • Deforestation destroys their habitat and drives them to extinction
      • Deforestation also results in loss of food as it brings about an imbalance in the eco-system
      • It also leads to an increase in the percentage of carbon dioxide in the air
      How does deforestation affect Animals
      • Example of an animal affected by deforestation:The Golden Lion Tamarin
      • Less than 3% of their original habitat remains today.
      • There are approximately 1500 left(500 in zoos).
      • Because of deforestation, their habitat has been fragmented into small unconnected areas,each only able to support a few tamarins thus breeding is affected leading to their endangerment.

      • Deforestation leads to a loss of food supply
      • Possible loss of medicines.
      • It could also lead to respiratory problems (as the percentage of carbon dioxide in the atmosphere has increased)
      • Various environmental hazards such as landslides and acid rain.
      • Causes greenhouse effect which causes global warming
      How does deforestation affect Humans
      • Deforestation causes top soil to be loosened because the roots of trees are no longer in the soil to hold the soil together
      • During rain, the top soil gets washed away and pollutes nearby water bodies
      How does deforestation cause water pollution
      • Oil spills, one of the most common forms of water pollution
        • Sea birds to die because their wings will be coated with oil that makes the feathers stick together and thus causing them the inability to fly
        • Poison the marine life
        • Prevents oxygen from dissolving into the water preventing aquatic plants from photosynthesizing and thus marine life which are dependent on plants for oxygen, food and shelter will in turn die.
      • Drinking polluted water could also cause deaths.
      • Water pollution caused by soil erosion
        • Makes water bodies muddy and thus prevent sunlight from reaching the aquatic plants,
        • These water plants cannot photosynthesize and will die
        • The aquatic animals which are dependent on the plants or food, oxygen and shelter will also die.
      How does Water Pollution affect life cyles of Plants and Animals
      • Drinking polluted water can cause typhoid and cholera
      • People swimming in dirty water can develop ear infections or other diseases.
