    Coral Reefs Coral Reefs Presentation Transcript

    • Coral Reefs! 3/25/10 By:RobAn Williams
    • No, not Christopher Reeve! Not to be confused with Chris Reeve… http://www.nirvanaclub.com/news/reeve.jpg
    • Purpose
      • Coral reefs contain 25% of all ocean fish
      • Most destruction to coral reefs is manmade (some is caused by hurricanes and storms.)
        • More than a quarter of the earth’s coral reefs have been destroyed by humans.
    • Organization
      • What are coral reefs
      • Organisms in reefs
      • Types of coral reefs
      • Coral reef biodiversity
      • Threats to coral reefs
      • Great Barrier Reef
      • Protection and Restoration
    • What are coral Reefs?!
      • Coral is a stony substance that is made of the skeletons of certain kinds of tiny sea animals called polyps.
      • Polyps produce limestone at their base, which makes coral hollow and acts as a hiding place when predators come.
      • Vary in shape, size and color.
      • Need warm water, sunlight, and clear, shallow water to survive.
    • Organisms in Reefs
      • Sponges, sea slugs, crustaceans, marine snails, sea stars, and fish.

    • Three Types of Coral Reefs…
      • Fringing Reefs : Border shorelines of continents and islands in tropical seas.
      • Barrier Reefs : Form when land masses sink, and fringing reefs separate from shorelines.
      • Atoll Reefs : Surround a central lagoon.

    • Coral Reef Biodiversity
      • Food source for coastal communities.
      • Sources of beach sand.
      • 1 million species of marine life make up its ecosystem.

    • Threats
      • Overfishing

    • Another Threat
      • Pollution
        • Enters through oil spills, acid rain, and hazardous waste, and exhaust from boats.
        • Kills reefs from poisons and heavy metals.
        • Enters the coral through polyps and kills them.

    • … MORE THREATS!
      • Global Warming
        • Heat created by global warming evaporates water leaving coral reefs above the water’s surface.
        • Once coral reefs are above water they cannot breathe, and die.

    • SO MANY THREATS!
      • Coral Bleaching
      • Ocean Acidification
      • Coral Mining
      • Threatened Species
        • Over 200 species (33%) are endangered .
        • 10 years ago only 2% were endangered.
        • Warmer sea temperatures lead to sudden sicknesses.

    • Great Barrier Reef
      • Largest coral reef in the world.
      • Made up of 3,000 coral reefs and 900 islands (1616 miles).
      • Off the coast of Queensland, Australia.
      • Home of many species of birds, whales, fish, sea turtles, and stingrays.
      • Large tourist area for scuba divers.
      • Native home to the Black Marlin.

    • Conclusion
      • Little ways to make a difference
        • Conserve water
        • Reduce pollution
        • Use organic fertilizers
        • Practice save diving
