Coral reef bleaching

Coral Reef Bleaching

By: Sarah Barash


What is coral reef bleaching

What is Coral Reef Bleaching?

  • Coral reef bleaching is caused by many factors but is basically when the coral is stressed and the coral expels the algae living in it


Why is coral important

Why Is Coral Important?

  • They shelter 25 percent of marine species

  • Protect shorelines

  • Support fishing industries

  • Tourist Attraction

  • Medical use

  • Biodiversity


Key terms

Key Terms

  • Zooxanthellae- a photosynthetic algae that lives in coral and gives the coral its color. The coral and zooxanthellae have a mutualism relationship

  • Sedimentation- particles mixing with water


How it is caused

How It Is Caused

  • Reduction of photosynthetic pigment concentrations in zooxanthealle

  • sea temperature (too hot)

  • Sedimentation

  • Foreign chemicals and nutrients (fertilizers, purchased dirt, etc.)

  • Freshwater

  • Overfishing


Areas that a re affected

Areas That Are Affected

  • Florida Keys

  • Caribbean

  • Gulf of Mexico

  • South Atlantic

  • Western Pacific


What will happen

What Will Happen?

  • Climate Change: the ocean will no longer be able to handle the carbon emissions in the ocean because the zooxanthealle will be gone

  • Ocean Acidification: the extra CO2 has already begun to decreasing the ocean’s pH level

  • Fishing Impact: the healthy coral acts as a home for many commercial fish

  • Pollution: can cause disease and change the trophic structure


Sediment

Sediment


Environmental impact

Environmental Impact

  • Trophic levels will be changed

  • Extreme human growth can cause over fishing bringing down biodiversity


How it affects the carbon cycle

How It Affects the Carbon Cycle


But you can help

But You Can Help!

  • Reduce Greenhouse Gases because scientists already predict a 1.8ºF raise in water temperature in the next century already due to the emissions

  • Reduce, Reuse, Recycle- be mindful of where your waste and runoff go!
