What causes coral bleaching at the Great Barrier Reef.

Great Barrier Reef:

  • The Great Barrier Reef is the world’s largest coral reef system composed of over 2,900 individual reefs and 900 islands.

  • The Great Barrier Reef can be seen from outer space and is the world’s biggest single structure made by living organisms.
  • This reef structure is composed of and built by billions of tiny organisms, known as coral polyps.
  • It supports a wide diversity of life and was selected as a World Heritage Site in 1981.

What is coral bleaching?

  • Coral reefs are threatened by climate change.
  • When the sea surface temperature increases beyond a tolerable limit, they undergo a process of bleaching. Bleaching is when the corals expel a certain algae known as zooxanthellae, which lives in the tissues of the coral in a symbiotic relationship. 
  • About 90% of the energy of the coral is provided by the zooxanthellae which are endowed with chlorophyll
  • and other pigments.
  • They are responsible for the yellow or reddish brown colours of the host coral. The zooxanthellae can live as endosymbionts with jellyfish also.
  • When a coral bleaches, it does not die but comes pretty close to it. Some of the corals may survive the experience and recover once the sea surface temperature returns to normal levels.

 How does it affect the Great Barrier Reef?

  • Climate change was the greatest threat to the Reef.
  • Coastal development, land-based run-off and direct human use, such as activities like illegal fishing.
