loss of bio diversity

  1. 1. HAS MANKIND CONSERVED BIO DIVERSITY???
  2. 3. WHAT IS BIO DIVERSITY?
  3. 4. This figure is called the Living Planet Index; it was compiled by the World Wildlife Fund in 2005, and is based on data for several groups of marine, freshwater, and terrestrial animal species. As you can see, abundance of all has declined since 1970 levels
  4. 5. THREATS TO BIO DIVERSITY?? <ul><li>DEFORESTATION </li></ul><ul><li>RAPID KILLING OF ANIMALS </li></ul><ul><li>GLOBAL WARMING </li></ul><ul><li>AND MAN </li></ul>
  5. 6. RAPID CUTTING OF FORESTS
  6. 7. Deforestation is the clearance of naturally occurring forests by the processes of logging and/or burning of trees in a forested area. There are several reasons deforestation occurs: trees or derived charcoal can be sold as a commodity and used by humans, while cleared land is used as pasture, plantations of commodities and human settlement. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity
  7. 8. 2 Clearing and burning vegetation 3 Constructing buildings 1 DENSE FORESTS
  8. 10. Animal cruelty is a worldwide problem rapidly growing in today's society. Animals are being beaten and starved everyday and millions of helpless animals die each year because of heartless owners .
  9. 11. ELEPHANTS and RHINOCEROS are widely killed all over the world for their tusks an skin They are on the edge of becoming extinct
  10. 12. DINASAURS MAMMOTH DODOS PANDAS RHINOCEROS POLAR BEAR ETC.
  11. 13. PICTURE OF GLACIERS 50 YEARS AGO PRESENT CONDITIONS OF GLACIERS
  12. 14. 1 Rainforests are experiencing biodiversity loss at rates greater than most other habitat types. The primary cause of rainforest loss is deforestation for timber, cattle grazing, and farming 2 Wetlands are another habitat being lost at great pace. Wetlands are very important to humans for a number of reasons, including storm mitigation and water filtration
  13. 15. 3 Coral reefs are extremely sensitive to changes in ocean temperature, and “coral bleaching” results when temperatures get too high; this phenomena will eventually kill corals if the temperature does not return to suitable levels SPECIES 4 Increased human use and pollution of the river degraded its habitat to the extent that it has been declared extinct The Golden Toad was a small, brightly colored toad .It has been extinct since 1989 Polar bears are one of the most well-known victims of climate change, because of global warming, they could be extinct by the end of this century.
  14. 16. Drowning of Earth because of melting Of glaciers THIS DAY IS NOT FAR
