Daniels Coral Reefs Daniel Tate

  1. 1. Dangers of Pollution and the Coral Reefs By: Daniel Tate
  2. 2. Did you know? <ul><li>That the warmth of the water can effect the coral reef. </li></ul><ul><li>The quality of water plays a big role, because it can reduce growth and can smother the coral polyps. </li></ul><ul><li>Industry is one of the top water polluters. </li></ul><ul><li>Cities also dump their raw waste in the sea which can clog the pores of the reef. </li></ul>
  3. 3. Also… <ul><li>Tankers spill into the sea causing the pores of a coral reef to get clogged. </li></ul><ul><li>Individual people that live on the river or on the beach dump garbage into the river or ocean and cause pollution of the reefs. </li></ul><ul><li>Traps, nets, and other fishing tools can destroy the coral reefs if they get tangled. </li></ul>
  4. 4. <<<BUT>>> <ul><li>Some things can be very healthy for the coral reefs. </li></ul><ul><li>If the wastes of humans are treated they can serve as a fertilizer for the coral reefs. </li></ul>
  5. 5. Interesting Facts and History <ul><li>The reefs are made of thousands of grouped colonies. </li></ul><ul><li>The reefs may die if they are not in water about 68-75 degrees Fahrenheit. </li></ul><ul><li>They need shallow and subtropical seas to live. </li></ul><ul><li>Coral reefs have developed over 2,000 years. </li></ul>
  6. 6. More Facts About the Reefs <ul><li>The United States Navy and the Japanese Navy fought a battle on the Coral Sea in the Pacific Ocean. </li></ul><ul><li>They are in the Phylum Cnidaria and their class is Anthozoa. </li></ul><ul><li>Coral reefs grow at an average .5-3 inches a year. </li></ul>
  7. 7. Diseases of the Coral Reefs <ul><li>There are 3 different types of bands of diseases. </li></ul><ul><li>The Black band affects brain and Star coral and moved like a wildfire throughout the reefs leaving a white skeleton behind. </li></ul><ul><li>The yellow band affects Boulder Star coral and resembles bleaching. </li></ul><ul><li>The white band destroyed 95% of the Elkhorn coral. </li></ul>
  8. 8. Other Diseases and What Cause them <ul><li>Climate change hurt the reefs and cause bleaching. </li></ul><ul><li>Bleaching is when stress affects little microscopic animals that provide color for the reefs. This is also known as zooxanthellae. </li></ul><ul><li>Bleaching has effected some of the Great Barrier Reef in Australia. </li></ul>
  9. 9. Different Types of Pollution <ul><li>Freshwater is loaded with silt, nitrogen, and phosphorus. </li></ul><ul><li>These materials in the freshwater can block the sunlight, therefore stopping photosynthesis and killing the reef. </li></ul><ul><li>Overabundance of freshwater has a lot of nutrients and can overload the reefs also causing death. </li></ul>
  10. 10. Other Types of Pollution <ul><li>Cutting down trees and deforestation also cause unhealthy environments for coral reefs. </li></ul><ul><li>Topsoil is washed into the coastal seas and block out sunlight that the reefs need. </li></ul><ul><li>Beach rebuilding washes sand and other pore-blocking particles out to the reefs. </li></ul>
  11. 11. Future of the Reefs <ul><li>The reefs are devastated by warm waters and global warming. </li></ul><ul><li>In 30 years, if there is nothing done about the climate, then ALL coral reefs WILL be destroyed from global warming. </li></ul><ul><li>An increase of about 1-2 degrees can kill coral reefs. </li></ul>
  12. 12. Us Too? <ul><li>If the coral reefs die, then we are also effected. </li></ul><ul><li>The economy will plummet because of the tourists not coming anymore. </li></ul><ul><li>14 of the oceans’ marine life live in the reefs. </li></ul><ul><li>This dramatically reduces the amount of seafood bought around the world. </li></ul>
  13. 13. Our Responsibility <ul><li>It is our responsibility to stop global warming and to protect the coral reefs that have been growing over thousands of years. </li></ul><ul><li>We also need to find another way to get rid of our wastes instead of dumping them into the oceans and rivers. </li></ul><ul><li>The world can band together to stop the destruction of the coral reefs. </li></ul>
