Final Project(BCA)- Estela Ria B. Espanilla BF

  1. 1. Deforestation
  2. 2. What is deforestation? <ul><li>Deforestation is the permanent destruction of indigenous forests and woodlands. The term does not include the removal of industrial forests such as plantations of gums or pines. </li></ul>
  3. 3. What are Forest and woodlands? <ul><li>In a forest the crowns of individual trees touch to form a single canopy. In a woodland, trees grow far apart, so that the canopy is open. </li></ul>
  4. 4. How does it happen? Used for Urban and Construction Purposes To Grow Crops
  5. 5. To Create Grazing Land Acid Rain
  6. 6. Mining Exploitation Wildfires
  7. 7. What are the Effects of Deforestation? <ul><li> Erosion of Soil </li></ul>When forest areas are cleared, it results in exposing the soil to the sun, making it very dry and eventually, infertile, due to volatile nutrients such as nitrogen being lost.
  8. 8. Disruption of the Water Cycle Trees contribute in a large way in maintaining the water cycle. They draw up water via their roots, which is then released into the atmosphere. A large part of the water that circulates in the ecosystem of rainforests, for instance, remains inside the plants. When these trees are cut down it results in the climate getting drier in that area.
  9. 9. Loss of Biodiversity Due to massive deforestation, about 50 to 100 species of animals are being lost each day. The outcome of which is the extinction of animals and plants on a massive scale.
  10. 10. Flooding One of the vital functions of forests is to absorb and store great amounts of water quickly when there are heavy rains. When forests are cut down, this regulation of the flow of water is disrupted, which leads to alternating periods of flood.
  11. 11. Climate Change When deforestation occurs, many of the trees are burnt or they are allowed to rot, which results in releasing the carbon that is stored in them as carbon dioxide. This, in turn, leads to greater concentrations of carbon dioxide in the atmosphere.
  12. 12. How to prevent deforestation: <ul><li>1. Plant trees and begin doing this in your yard. Trees also help in containing water in its roots. </li></ul><ul><li>2. Use recycled items such as books or pad paper, toilet paper, even shopping bags. If you can, do not waste any of these products so that no new raw material would be required to replace them. </li></ul>
  13. 13. 3. If you are a farmer try to rotate your crops. 4. Cut down only the mature trees. Do not kill baby trees. 5. Join environmental awareness groups that would help you be an advocate of reforestation. 6. Instead of using firewood, use coals to heat up your fireplaces during the winter season. Remember that it takes only a few hours to consume the firewood but it would take years to grow a single tree. Think twice before purchasing firewood again.
