  1. Coral Reefs! 3/25/10 By:RobAn Williams
  2. No, not Christopher Reeve! Not to be confused with Chris Reeve… http://www.nirvanaclub.com/news/reeve.jpg
  3. Purpose <ul><li>Coral reefs contain 25% of all ocean fish </li></ul><ul><li>Most destruction to coral reefs is manmade (some is caused by hurricanes and storms.) </li></ul><ul><ul><li>More than a quarter of the earth’s coral reefs have been destroyed by humans. </li></ul></ul>
  4. Organization <ul><li>What are coral reefs </li></ul><ul><li>Organisms in reefs </li></ul><ul><li>Types of coral reefs </li></ul><ul><li>Coral reef biodiversity </li></ul><ul><li>Threats to coral reefs </li></ul><ul><li>Great Barrier Reef </li></ul><ul><li>Protection and Restoration </li></ul>
  5. What are coral Reefs?! <ul><li>Coral is a stony substance that is made of the skeletons of certain kinds of tiny sea animals called polyps. </li></ul><ul><li>Polyps produce limestone at their base, which makes coral hollow and acts as a hiding place when predators come. </li></ul><ul><li>Vary in shape, size and color. </li></ul><ul><li>Need warm water, sunlight, and clear, shallow water to survive. </li></ul>
  6. Organisms in Reefs <ul><li>Sponges, sea slugs, crustaceans, marine snails, sea stars, and fish. </li></ul>http://student.britannica.com/comptons/art/print?id=55468&articleTypeId=0
  7. Three Types of Coral Reefs… <ul><li>Fringing Reefs : Border shorelines of continents and islands in tropical seas. </li></ul><ul><li>Barrier Reefs : Form when land masses sink, and fringing reefs separate from shorelines. </li></ul><ul><li>Atoll Reefs : Surround a central lagoon. </li></ul>http://oceanservice.noaa.gov/education/kits/corals/media/coral05a_480.jpg
  8. Coral Reef Biodiversity <ul><li>Food source for coastal communities. </li></ul><ul><li>Sources of beach sand. </li></ul><ul><li>1 million species of marine life make up its ecosystem. </li></ul>http:// www.eco-asia.info/content/sites/default/files/images/tr-wakatobi-underwater.jpg
  9. Threats <ul><li>Overfishing </li></ul>http://www.grinningplanet.com/2005/06-07/fishing-cycle.gif
  10. Another Threat <ul><li>Pollution </li></ul><ul><ul><li>Enters through oil spills, acid rain, and hazardous waste, and exhaust from boats. </li></ul></ul><ul><ul><li>Kills reefs from poisons and heavy metals. </li></ul></ul><ul><ul><li>Enters the coral through polyps and kills them. </li></ul></ul>http://www.epd.gov.hk/epd/english/envir_education/envir_explorer/images/explorer_4_01.gif
  11. … MORE THREATS! <ul><li>Global Warming </li></ul><ul><ul><li>Heat created by global warming evaporates water leaving coral reefs above the water’s surface. </li></ul></ul><ul><ul><li>Once coral reefs are above water they cannot breathe, and die. </li></ul></ul>http://www.instablogsimages.com/images/2007/11/28/damaged-coral-reef_6697.jpg
  12. SO MANY THREATS! <ul><li>Coral Bleaching </li></ul><ul><li>Ocean Acidification </li></ul><ul><li>Coral Mining </li></ul><ul><li>Threatened Species </li></ul><ul><ul><li>Over 200 species (33%) are endangered . </li></ul></ul><ul><ul><li>10 years ago only 2% were endangered. </li></ul></ul><ul><ul><li>Warmer sea temperatures lead to sudden sicknesses. </li></ul></ul>http://pixdaus.com/single.php?id=29474
  13. Great Barrier Reef <ul><li>Largest coral reef in the world. </li></ul><ul><li>Made up of 3,000 coral reefs and 900 islands (1616 miles). </li></ul><ul><li>Off the coast of Queensland, Australia. </li></ul><ul><li>Home of many species of birds, whales, fish, sea turtles, and stingrays. </li></ul><ul><li>Large tourist area for scuba divers. </li></ul><ul><li>Native home to the Black Marlin. </li></ul>http://www.dianibeach.co.uk/Black_Marlin.jpg
  14. Conclusion <ul><li>Little ways to make a difference </li></ul><ul><ul><li>Conserve water </li></ul></ul><ul><ul><li>Reduce pollution </li></ul></ul><ul><ul><li>Use organic fertilizers </li></ul></ul><ul><ul><li>Practice save diving </li></ul></ul>
  15. MuLtIpLe ChOiCe QuEsTiOn <ul><li>Which type of coral reef surrounds a central lagoon? </li></ul><ul><li>A) Fringing reef </li></ul><ul><li>B) Barrier reef </li></ul><ul><li>C) Atoll reef </li></ul>
  16. C) Atoll reef
