  • Massive extinctions have occurred five times during the earth's history, the last one was the extinction of the dinosaurs, 65 million years ago. Scientists are calling what is occurring now, the sixth mass extinction. The loss of species is about losing the very web of life on Earth
  • Within the next 30 years as many as half of the species on the earth could die in one of the fastest mass extinctions in the planet's 4.5 billion years history.
  • There is also the loss of the genetic diversity within species, as well as the loss of diversity of different types of ecosystems ,which can contribute to or hasten whole species extinction.

  • "Every day, an estimated 100 plant and animal species are lost to deforestation" . . . "A conservative estimate of the current extinction rate indicates that about 27,000 species a year are being lost." National Wildlife Federation

  • The review, published in the journal Conservation Biology, highlights destruction and degradation of ecosystems as the main threat. In Australia, agriculture has altered or destroyed half of all woodland and forests. Around 70% of the remaining forest has been damaged by logging. Loss of habitats is behind 80% of threatened species, the report claims.
  • More than 2,500 invasive plant species have colonised Australia and New Zealand, competing for sunlight and nutrients. Many have been introduced by governments, horticulturists and hunters. In addition, the report says, average temperatures in Australia have increased, in line with climate change predictions, forcing some species towards Antarctica and others to higher, cooler ground.

      The species are dying at a alarming rate already and if we destroy the rain forest even more the web of life will be effected badly

  • A look at the botanical treasures, both known and undiscovered, that exist within tropical rainforests.
  • The abundant botanical resources of tropical forests have already provided tangible medical advances; yet only 1 percent of the known plant and animal species have been thoroughly examined for their medicinal potentials.
  • 20 or 25 percent of the world's plant species will be extinct by the year 2000.

  • Approximately 7,000 medical compounds prescribed by Western doctors are derived from plants
  • These drugs had an estimated retail value of US$43 billion in 1985
  • For maladies ranging from nagging headaches to lethal contagions such as malaria, rainforest medicines have provided modern society with a variety of cures and pain relievers.
  • • Quinine, an aid in the cure of malaria, is an alkaloid extracted from the bark of the cinchona tree found in Latin America and Africa. • From the deadly poisonous bark of various curare lianas, used by generations of indigenous peoples in Latin America, has been isolated the alkaloid d-turbocuarine, which is used to treat such diseases as multiple sclerosis, Parkinson's disease and other muscular disorders. It also permits tonsillectomies, eye, abdominal and other kinds of surgery due to its anesthetic qualities. • From Africa, Madagascar's rosy periwinkle provides two important anti-tumor agents. One provides for a 99 percent chance of remission in cases of lymphocytic leukemia. The other offers a life in remission to 58 percent of Hodgkin's Disease sufferers. In 1960, only 19 percent had a chance for survival. Commercial sales of drugs derived from this one plant are about US$160 million a year. • Without wild yams from Mexico and Guatemala, society would be without diosgenin and cortisone, the active ingredients in birth control pills. Until recently this plant provided the world with its entire supply of diosgenin.
  • Finally, rainforest plants provide aids for research.
  • testing agents for potentially harmful food and drug products
  • Tropical forests offer hope for safer contraceptives for both women and men. The exponential growth of world population clearly demonstrates the need for more reliable and effectiv
  • e birth control methods. Worldwide, approximately 4,000 plant species have been shown to offer contraceptive possibilities.
  • The chemical components of plants that medicine men use in healing rites could conceivably be building blocks for new drugs or even cures for such scourges as cancer or AIDS.

    Whenever people talk about deforestation, usually the things that spring to mind are negative thoughts brought on mostly by media hypes and environmentalist drives. People think about global warming, depletion of natural resources, and the casual extinction of indigenous fauna and flora. Yet people don't seem to realize that there are actually quite a few benefits of deforestation.

    By SYLVIA WESTALL Love your new dining room table ... but did you ask the salesman whether it's made from chopped up rainforest trees? A growing number of shoppers are doing just that when buying furniture because of concerns about the effects of shrinking rainforests on global warming and the extinction of rare species of flora and fauna that inhabit these forests.
