The Great Coral Barrier in Australia
The clock runs and the hours are counted for this great coral barrier, without urgent actions against global warming, it will be extinguished in its entirety. Australia, has a great natural biodiversity, among the species that forms it is the coral barrier, threatened by the bleaching that has made half of the corals of an extension of 2,300 square kilometers be lost in 30 years and, the same barrierRecovery is resisting because there are less mature corals and very few nascent corals, chemicals spotted in the sea are already inhibiting the growth of more.
The most worrying thing for scientists, experts on the subject, is that the greatest corals disappear, because that proportion took them years to reach it and with it great genetic information that they can transmit to the young of corals to help them with their resistance, ofdie or fragment the coral, this information will not go to the outbreaks, function as large carbon stores.
The coral is extremely sensitive to changes in temperature, light or nutrients and it is evident that they cannot be transferred to a part of the ecosystem where these changes are not so sudden, therefore they stress, which causes them to expel algae thatThey inhabit their tissues, leaving them completely white and unusable and unprotected by making them susceptible to choral’s own diseases. They also perform carbon absorption through a photosynthetic process, which cannot be done without its symbiotic algae.
This recent study published in the Journal Proceedings of the Royal Society B, disappearance of the Great Barrier of Coral from 1995 to 2017, in this period the corals endured cyclones and environmental catastrophes, in 2016 and 2017 the phenomenon of El Niño, wasThe one that most damage the barrier causing 4 mass bleaching and caused the epidemic of sea stars with crown of thorns, the major damage is located in the central and northern region.
If not to reduce carbon emissions, by the end of this century the great coral barrier will be complete. The Paris Agreement stipulates that the decrease must reach 1.5 – 2 ° C to still have a coral barrier, already 5 years of the agreements and there is no commitment for the countries within the agreement.
