The Causes Of Deforestation

  1. 1. The Causes of Deforestation By: Nate Gould
  2. 2. What is deforestation? <ul><li>Deforestation is the process of clearing forests by…. </li></ul><ul><ul><li>Cutting down trees </li></ul></ul><ul><ul><li>Burning </li></ul></ul>
  3. 3. Methods <ul><li> </li></ul>Digital Maps
  4. 4. Economics <ul><li>120 households in Amerindian economies. </li></ul><ul><li>Factors were recorded such as </li></ul><ul><ul><li>Length of residence </li></ul></ul><ul><ul><li>Household wealth </li></ul></ul><ul><ul><li>Morbidity </li></ul></ul><ul><ul><li>Looking for a relationship between an areas wealth and rate of deforestation. </li></ul></ul>
  5. 5. Economics Cont… <ul><li>Keeping an eye on our natural resources </li></ul><ul><li>Used 1990 census and digital maps to determine cultivable land. </li></ul><ul><li>Tested: </li></ul><ul><ul><li>Soil quality </li></ul></ul><ul><ul><li>Precipitation </li></ul></ul><ul><ul><li>Infastructure </li></ul></ul><ul><ul><li>How much money are we losing by removing these natural resources? </li></ul></ul>
  6. 6. Carbon <ul><li>Seems to be a correlation between deforestation and lower amounts of carbon. </li></ul><ul><li>Carbon balance was watched over a two year period. </li></ul><ul><li>Found the balance of carbon between the atmosphere and the biosphere. </li></ul>
  7. 7. Results <ul><li>Found three main reasons for deforestation. </li></ul>Agriculture Wood use Roads
  8. 8. Agriculture <ul><li>Population Food </li></ul>As our population increases, we need more land to grow crops and food to feed the people. <ul><li> </li></ul>
  9. 9. Wood Use <ul><li>Wood is used for </li></ul><ul><li>-fuel </li></ul><ul><li>-exporting </li></ul><ul><li>Trees are being cut down before they have time to grow back. </li></ul>
  10. 10. Roads <ul><li>Roads are being built closer to forests. </li></ul><ul><li>Need more land for people to live </li></ul><ul><li>Need more roads to transport the products growing in the forests. </li></ul>Even in Michigan
  11. 11. How quick is deforestation happening?                                                                     Source: UNEP, 2007. Rapid Response Assessment: The Last Stand of the Orangutan Deforestation Trends in Borneo
  12. 12. Discussion <ul><li>We need more food (Agriculture) </li></ul><ul><li>We need more fuel and firewood (Wood) </li></ul><ul><li>We need more roads and areas to live (Roads) </li></ul> http://
  13. 13. What do we do? <ul><li>If we want to save the forests, we have to find alternate methods for </li></ul><ul><ul><li>Food </li></ul></ul><ul><ul><li>Fuel </li></ul></ul><ul><ul><li>Roads and housing </li></ul></ul>Build up Alternate fuel sources / /
