Facts About The Great Barrier Reef Is Bleaching Due To Rising Sea Water Temperature

Great Barrier Reef
The great barrier reef is facing third bleaching event in previous five years. Generally the great barrier reef bleaches for one time in every five years. But eventually by increasing of global warming coral reefs have been suffering form of a large damage.

What Is Coral Reefs?
Coral are looking like broken rock but these are the one types of creatures which are formed by "polyps". Polyps have a sack like body with many tentacles. These polyps creatures are formed into rock like structure by gaining of calcium carbonate from sea water. Polyps and algea are symbiotic creatures when they found together then called it coral and when many corals are found in a specific region then that region known as coral reef. The algea absorb light from sun and subsequently feed to the polyps. Algae also provide their bright colours to coral so coral's outlooks is very colourful.

The great barrier reef is the world's largest coral reef which situated in Australia. Australian tourism department state that the great barrier reef's estimated value is 56 billion USD. This damage also affect on the Australia's economy because the great barrier reef provide 64,000 jobs and contribute 4.6 billion USD to australian economy.

Due to increasing of global warming sea water temperature also increased which is at risk of losing this world heritage site. The northern side of the great barrier reef faced bleaching two times in 2015 & 2017 so it is also effect on tourism industry because the northern reef coral's outlooks quality is very poor. So australian government agency overlooking the health quality of the coral reef to improving it.



Does Recover Coral Reef After Bleaching?
Coral reefs damaged by the increasing of temperature of sea water, after reduce sea water temperature it can recovered. When climates temperature increases that symbiotic algae will die, after died of algae corals are become foodless and colourless (become white) which impact on outlook quality of coral reef. Polyps creatures are facing the risk of starvation and disease but corals can recover after decreasing of sea water temperature and also growing the algae.


The Great Barrier Reef Facts

  1. The great barrier reef is the largest coral reef system in the world which are a about 344,000 square km.
  2. There are 2900 individuals reefs and 900 islands are stretching for 2300 km.
  3. The great barrier reef is created an amazing diversity for many species these are 6 species of trutles, 17 species of snakes and 30 species of whales.
  4. There are 10% of the world's total fish species are available within in the great barrier reef.
  5. The new coral are sat on the old corals. Some of old corals are existing from 20 million years ago.
