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