Transcript of "3 J Zach And Shaun Deforestation Presentation"

  1. 1. Deforestation & Water Pollution
  2. 2. It is the permanent destruction of forests and woodlands for various purposes (eg. farming activies, setting up factories etc) What is Deforestation?
  3. 3. <ul><li>Deforestation destroys their habitat and drives them to extinction </li></ul><ul><li>Deforestation also results in loss of food as it brings about an imbalance in the eco-system </li></ul><ul><li>It also leads to an increase in the percentage of carbon dioxide in the air </li></ul>How does deforestation affect Animals
  4. 4. <ul><li>Example of an animal affected by deforestation:The Golden Lion Tamarin </li></ul><ul><li>Less than 3% of their original habitat remains today. </li></ul><ul><li>There are approximately 1500 left(500 in zoos). </li></ul><ul><li>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. </li></ul>Golden Lion Tamarin
  5. 5. <ul><li>Deforestation leads to a loss of food supply </li></ul><ul><li>Possible loss of medicines. </li></ul><ul><li>It could also lead to respiratory problems (as the percentage of carbon dioxide in the atmosphere has increased) </li></ul><ul><li>Various environmental hazards such as landslides and acid rain. </li></ul><ul><li>Causes greenhouse effect which causes global warming </li></ul>How does deforestation affect Humans
  6. 6. <ul><li>Deforestation causes top soil to be loosened because the roots of trees are no longer in the soil to hold the soil together </li></ul><ul><li>During rain, the top soil gets washed away and pollutes nearby water bodies </li></ul>How does deforestation cause water pollution
  7. 7. <ul><li>Oil spills, one of the most common forms of water pollution </li></ul><ul><ul><li>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 </li></ul></ul><ul><ul><li>Poison the marine life </li></ul></ul><ul><ul><li>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. </li></ul></ul><ul><li>Drinking polluted water could also cause deaths. </li></ul><ul><li>Water pollution caused by soil erosion </li></ul><ul><ul><li>Makes water bodies muddy and thus prevent sunlight from reaching the aquatic plants, </li></ul></ul><ul><ul><li>These water plants cannot photosynthesize and will die </li></ul></ul><ul><ul><li>The aquatic animals which are dependent on the plants or food, oxygen and shelter will also die. </li></ul></ul>How does Water Pollution affect life cyles of Plants and Animals
  8. 8. <ul><li>Drinking polluted water can cause typhoid and cholera </li></ul><ul><li>People swimming in dirty water can develop ear infections or other diseases. </li></ul>How does Water Pollution affect Humans
