Rainforest powerpoint[1]

  1. 1. Where Have All the Rainforests Gone?
  2. 2. Losing Earth’s Greatest Biological Treasure <ul><li>Rainforests once covered 14% of the Earth’s surface </li></ul><ul><li>Now they cover a mere 6% </li></ul>
  3. 3. <ul><li>One-half acres of rainforest are lost every second. </li></ul>
  4. 4. <ul><li>One hectare (2.47 acres) may contain over 750 types of trees and 1500 species of higher plants. </li></ul>
  5. 5. <ul><li>Rainforests are being destroyed for the value of timber. </li></ul>
  6. 6. <ul><li>Agricultural demands and cattle ranching are another cause for deforestation </li></ul>
  7. 7. <ul><li>The United Nation's Food and Agriculture Organization estimates that '1.5 billion of the 2 billion people worldwide who rely on fuel wood for cooking and heating are overcutting forests'. This problem is worst in drier regions of the tropics. Solutions will probably involve a return to local peoples' control of the forests they depend on. </li></ul>
  8. 8. What About the Ecosystem? <ul><li>Nearly half of the world’s species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation. </li></ul>
  9. 9. <ul><li>Experts estimate that we are losing 137 plant, animal and insect species every single day. </li></ul><ul><li>That is 50,000 species a year. </li></ul>
  10. 10. <ul><li>Most rainforests are cleared by chainsaws, bulldozers and fires for it’s timber value, followed by farming and ranching operations. </li></ul>
  11. 11. <ul><li>There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. </li></ul><ul><li>Today there are less than 200,000. </li></ul>
  12. 12. <ul><li>The Amazon Rainforest alone produces 20% of the world’s oxygen, earning the name “Lungs of our Planet” </li></ul>
  13. 13. The Rainforest and Medicine <ul><li>25% of western pharmaceuticals are derived from rainforest ingredients. </li></ul><ul><li>Less than 1% of these tropical trees and plants have been tested by scientists. </li></ul>
  14. 14. <ul><li>Currently 121 prescription drugs currently sold worldwide come from plant-derived sources. </li></ul>
  15. 15. <ul><li>The U.S. National Cancer Institute has identified 3,000 plants that are active against cancer cell. </li></ul><ul><li>70% of these plants are found in the rainforest. </li></ul>
  16. 16. <ul><li>Vincristine, extracted from the rainforest plant, Periwinkle, is one of the world’s most powerful anticancer drugs. </li></ul><ul><li>It has dramatically increased the survival rate for acute childhood leukemia since it’s discovery. </li></ul>
  17. 17. Rainforest Action <ul><li>Experts agree that by leaving the rainforests intact the rainforest has more economic value than if they were cut down to make grazing land for cattle, or timber. </li></ul>
  18. 18. <ul><li>Land converted to cattle operations yields the owner $60 per acre. </li></ul><ul><li>Land harvested for timber is worth $400 per acre. </li></ul><ul><li>If these renewable and sustainable resources are harvested, the land will yield the land owner $2,400 per acre. </li></ul>
  19. 19. <ul><li>If managed properly, the rainforest can provide the world’s need for these natural resources on a perpetual basis. </li></ul>
  20. 20. Solutions for Saving Our Rainforests <ul><li>Timber Labeling: the FSC </li></ul><ul><li>Addressing the Problem of Landlessness </li></ul><ul><li>Poverty, Debt and Inequality </li></ul><ul><li>Population </li></ul><ul><li>Returning Power to Local Communities: </li></ul><ul><li>Ending the Use of Tropical Timber: </li></ul>
  21. 21. Timber Labeling: the FSC
  22. 22. Addressing the Problem of Landlessness <ul><li>Poor farmers opening up rainforest land for subsistence farming are the agents of more rainforest loss than any other single factor. </li></ul><ul><li>Industrialized countries can help ease the pressures by reducing their demand for cash crops grown in the tropics and by ceasing to give financial aid to development projects. </li></ul>
  23. 23. Poverty, Debt and Inequality <ul><li>More than $1300 billion is owed by the third world to rich countries </li></ul><ul><li>To repay the huge amounts owed, these countries have to sacrifice their environment, as well as health and education </li></ul>
  24. 24. Population <ul><li>There can be no lasting solutions to this or any other global environmental calamity until the problem of overpopulation is successfully confronted. </li></ul>
  25. 25. <ul><li>Solving the problem of overpopulation will involve: more widespread acceptance of the importance of replacement reproduction (no more than two children per couple), equality for women, education, particularly for women and cheap and available contraception. </li></ul>
  26. 26. Returning Power to Local Communities <ul><li>Ecological degradation is characteristically linked to the disempowerment of local communities. </li></ul><ul><li>control over land use is taken from the people who live on the land in question and given to centralized governments . </li></ul><ul><li>This means that control is no longer in the hands of those who have a vested interest in maintaining the land. </li></ul><ul><li>It is in the hands of those who gain from its exploitation. This process needs to be reversed and power given back to local communities. </li></ul>
  27. 27. Ending the Use of Tropical Timber <ul><li>Tropical timber is used in many ways, and in all cases, there are suitable alternatives available. </li></ul><ul><li>In Australia and other rich countries, rainforest groups provide information on the environmental impact of using tropical timber, and on how these timbers can be avoided. </li></ul>
