Scientists recently found out that the Great Barrier Reef has lost corals since 1995. It is the most extensive system of reefs that are declining at a rapid rate. The probable reason for such a condition is the constant negative climate change. The bleaching events in 2016 and 2017 have led to the steepest corrosion of corals of all time. Unfortunately, it was not a lesson enough, and bleaching activities took place this year as well. Researchers worldwide are suggesting that the condition cannot worsen. Therefore, the only way to make it better is to control the emission of Greenhouse gases quickly.
Recently, a study in which scientists were analyzing the size and health of all coral colonies across the whole reef between 1995-2017. According to the final reports, over 50% drop in the population of corals of all species and sizes. Moreover, the conditions of the table-shaped and branching corals were worse. The underwater ecosystem is in massive danger. Justifying such a threat is that these corals were home to most marine life, including fishes. So, gradually these species are losing their home, leaving them exposed to much danger and pollution.
Great Barrier Reef has lost corals that can take decades to recover.
The struggle for corals to regenerate is enormous because most adult corals did not survive the torture. However, for the coral system to grow, there must be adult corals and new and colorful ones. According to scientists, the Great Barrier Reef is indeed showing quite some resilience. However, the hope of regeneration is quite faint, considering the scarcity of adult corals. Therefore, the breeding process will take a lot longer than usual. We have to wait for the baby corals to grow and reach the stage when they are fit to produce further generations.
According to the Reef Agency of Australia, the most massive threat to coral loss is human activities. These are the same activities that are generating pollution and leading to the warming of the climate. While bleaching activities do not seem to stop, researchers are relentlessly working to assess the level of damage. They are also trying to find any better options to protect further loss of the beautiful Great Barrier Reef. It is not just unique to Australia, but a World Heritage indeed.
