  1. welcome to my science presentation.
  2. My name is Sumit and I'm from class 84 and
  3. today I will be talking about ocean acidification.
  4. Let's get on to our first question.
  5. Why is coral important?
  6. Coral reefs protect from storms and erosion, provide jobs for
  7. local communities and off offer opportunities for recreation.
  8. They're also a source of food and new medicines.
  9. Coral reefs are also considered cultural and important to some
  10. indigenous people around the world.
  11. What is coral medo?
  12. Yeah, Coral is made up of tiny creatures called polyps.
  13. Each polyp is a soft body politic, as thick as
  14. an echo.
  15. As you can see in the picture, Um, it is
  16. having a more zoomed in picture of the pubs, and
  17. that's how they look.
  18. What is happening to the coral warming waters.
  19. Pollution, ocean acidification, overfishing and physical destruction are destroying and
  20. killing our cultural reefs.
  21. What is the ocean acidification?
  22. What causes ocean acidification and what are the impacts?
  23. Ocean acidification is a decrease in the pH of the
  24. Earth's oceans.
  25. Also, carbon dioxide, which is produced from burning fossil fuels,
  26. is changing the fundamental chemistry of the oceans.
  27. Ocean acidification is caused by carbon dioxide gasses in the
  28. atmosphere dissolving into the ocean, causing the pH toured or
  29. making it more acidic.
  30. This may make it harder for coral and some plankton
  31. to share it to make their shows, which also make
  32. our existing shells to dissolve with shell fish in the
  33. ocean. Can't make their shelf.
  34. They will die or get affected.
  35. Are polluted by pollution.
  36. Ocean acidification may affect humans, too, because most of the
  37. shellfish we eat aren't allowed to make proper shells due
  38. to lack of calcium.
  39. And you know what happens if you can't make show
  40. they die or they get booted?
  41. What are dead zones?
  42. And what creates dead zones that Dillinger places in the
  43. world, where some linked to notions can't support the marine
  44. life living in it, causing all real life to die
  45. in the area?
  46. Dead zones are very low in oxygen, more hypoxic, which
  47. results in killing marine life in it that don't occur
  48. when a body of water gets take, gets or takes
  49. in too many nutrients.
  50. Some main nutrients are phosphorus and nitrogen.
  51. Nitrogen can cause over stimulation in the water, which makes
  52. things grow faster and clogs water intake.
  53. Phosphorus is an essential in plant life booking cars.
  54. You'd have eutrophication process to speed up if there is
  55. too much cause of it, causing reduction of dissolved oxygen
  56. in the water bonds.
  57. Human activities are the main cause of these dead zones
  58. because they're being footed with access nutrients from our human
  59. activities due to an easier access of nutrients.
  60. Dead zones mostly form dad dooms mostly formed near coastland.
  61. What is important to understand what is happening below the
  62. water, especially with regards to coral coral reefs, as you
  63. know, protect the coastlines from storms and erosion.
  64. But ocean acidification are destroying them basically.
  65. And that may cause harm to humans on marine life
  66. because it is basically kind of their home for many
  67. small fishes.
  68. And also what if a coral could make new medicines
  69. for some diseases in the world we have that would
  70. be helpful to what can we do to reduce or
  71. slow down ocean acidification?
  72. The most effective way to reduce ocean acidification is produce
  73. global warming so basically cut down on factors of global
  74. warming such as burning fossil fuels.
  75. If we think of preventing future global warming, we basically
  76. helping with the future ocean acidification.
  77. I'm basically saying that we will have less or should
  78. I certification?
  79. If we produce less carbon dioxide, which causes global warming?
  80. That's it for my science presentation today and bye for
  81. now.
