Ocean deprivation

  1. 1. Oceanic Deprivation<br />By Morgan, Aly, Chad, and Alisha <br />
  2. 2. Coral Bleaching-Quick Facts<br /><ul><li>65% of The Great Barrier Reef has been affected by coral bleaching.
  3. 3. 40% of the worlds coral will be dead from coral bleaching by 2010.
  4. 4. Found along islands and live in nutrient poor water.
  5. 5. More than 1,000 different species thrive in coral reef.
  6. 6. If coral bleaching doesn’t slow down it will completely die out in 1-3 decades
  7. 7. They have an extremely high biodiversity and productivity.
  8. 8. Reasons for Coral Bleaching: 1.)Temperature 2.) UV Radiation 3.) Atmosphere Exposure 4.)Sedimentation 5.) Freshwater dilution.
  9. 9. GLOBAL WARMING!!!!</li></li></ul><li>What is Coral Bleaching?<br />Definition: the release of the symbiotic colored algae normally living within coral animals, which occurs when coral animals are stressed (by high temperatures, for example) and makes the coral appear whites.<br />Symbiotic Colored Algae: Zooxanthellae: Gives color and protection for the coral reef along with there ability to live and thrive. They assist the coral to produce nutrients. Without this their physical appearance would be clear.<br />
  10. 10. Coral from Space<br />
  11. 11. Normal vs. Bleached<br />
  12. 12. Global Warming<br />Definition: Depletion of the ozone layer and warming of the planet.<br />Causes: Factories, Trucks/Cars, Deforestation, ect.<br />They admit chlorine through industrial produced CFC’s of gas.<br />Raises temperature within the atmosphere and lets in ultraviolet rays from the sun. <br />CO2,CH4, CFC, NO cause infrared rays to get trapped in the atmosphere.<br />
  13. 13. Consequences of Global Warming<br />Ultraviolet rays that reach Earths surface cause coral bleaching.<br />The temperature increase causes coral bleaching.- As little of an increase of 1 degree Celsius can cause coral bleaching.<br />1,000 species could potentially lose their home.<br />Ice is melting- Polar bears have little habitat and a great loss of hunting grounds. Heat exhaustion is affecting them also. - They will go extinct within the wild within the next few decades.<br />
  14. 14. HELP!!!!!!!<br />
  15. 15. Ways to Help Prevent Global Warming<br /><ul><li>Green Energy: Wind, Solar, Geothermal Power!
  16. 16. The Government of the United States must take ACTION!
  17. 17. People Must Take ACTION!
  18. 18. Live more sustainably.
  19. 19. Shut off lights and electronics when not used.
  20. 20. Use clothes line instead of dryer.
  21. 21. Shut off water when not in use.
  22. 22. RECYCLE
  23. 23. Plant trees
  24. 24. Car pool
  25. 25. Educate Others.</li></li></ul><li>OCEAN POLLUTION<br />
  26. 26. Pollution Chain<br />80 % of marine pollution comes from land based activities.<br />Pollution deposits in the waters and estuaries<br />Build up there concentrations, become toxic<br />Become part of marine food chain<br />Don’t care till human casualties<br />
  27. 27. Where Else Does It Go<br />Doesn’t stop and stay in water<br />Many currents take it for a ride<br />Wind moves rubbish around real good<br />Washes ashore on coast line<br />Pollutes land to the sea, and back to the land<br />Never ending battle with an enemy that cant quit without human action<br />
  28. 28. Major Pollutants<br />
  29. 29. OIL<br />
  30. 30. Where does it come from<br />Only 2 % of hydro carbon pollution comes from tanker accident<br />11% is from natural sources (tar-sands, oil seeps)<br />13% comes from the atmosphere<br />24% comes from all forms of transport<br />50% comes from drains and rivers leading into the sea<br />- US National Science Foundation<br />
  31. 31. Seems small<br />Tankers accidents may only be 2%<br />But in 1967 <br /> - Torrey Canyon ran aground off the English channel<br /> - 106,000 tons of oil <br /> - smallest of tanker accident,<br />2% is not small<br />
  32. 32. A Very Big Accident<br />http://www.youtube.com/watch?v=G1U-iWUPOYA <br />
  33. 33. Exxon Valdez <br />20,000 barrels an hour<br />256,000 gallons afternoon<br />11 million gallons <br />Biggest Tanker Accident to happen on American waters<br />
  34. 34. Exxon Valdez<br /><ul><li>Covered 10,000 square miles
  35. 35. Connecticut, Rhode Island, and 25 Washington DC’s
  36. 36. Week goes, currents and winds take over
  37. 37. Pushes 90 miles from site into Alaskan Gulf
  38. 38. 600 miles away
  39. 39. +130,000 miles contaminated</li></li></ul><li>Exxon Valdez<br />Wild life<br />Quarter of a million sea birds<br />1000 sea otters<br />300 harbor seals<br />250 bald eagles<br />At least 20 orca<br />Billions of salmon and ruined many <br />

  45. 45. Recovery in Prince William Sound?<br />http://www.youtube.com/watch?v=MbjC9SMKClE<br />
  46. 46. Seems Big<br />Exxon Valdez horrible accident<br />1980 Norwuz Field Spill<br /> - Arabia 80 Million Gallons<br />1992 Fergana Valley Spill<br /> - Uzbekistan 80 Million Gallons<br />
  47. 47.
  48. 48.
  49. 49. Other forms of major pollution<br />Nuclear/Radioactive waste<br />Sewage<br />Munitions disposal<br />
  50. 50. WWFCNWorld Wildlife Fund Conservation Network<br /><ul><li>Cause: To help oceans from becoming overburdened and under-protected.
  51. 51. Main fights: Over fishing and Runoff Pollution
  52. 52. The Law of the Sea Treaty</li></li></ul><li>“The Law of the Sea Treaty”<br />Includes rules that govern airspace, subsoil, and sea beds.<br />158 Nations have joined this treaty since established in 1982, but the United States has failed to yet. Until we have, we will have no voting power in ratifying the future of our oceans.<br />The United States will suffer economically due to the new issue on the future Arctic Ocean. <br />
  53. 53. OVERFISHING<br />75% of Marine environment has been overfished. <br /> Without laws to protect the fish population from being overfished, 950 million people will lose their main source of protein.<br />Could cause us to lose large numbers of species and/or biodiversity within the ecosystem of the ocean.<br />Once you have affected the population of fish, you affect other species by depleting their food source and the ecosystems cycle of life.<br />
  54. 54. Pollution and Littering<br />Runoff- Septic tanks, car fuels, boats, chemicals from farms and ranches.<br />Littering- Garbage bags, balloons, plastic, cigarette filters.<br />OIL SPILLS!<br />
