Great Barrier Reef Is Being Reshaped by Global Heating for Good, Except It’s Bad

 Picture a city, with complex architecture, gardens, buildings, roads, valleys, lots of crannies and nooks buzzing with life. The oceans have cities too. Perhaps not Atlantis, per se, but coral. Coral reefs are the cities of the marine ecosystem, constructed by animals that have a soft figure covered by a tough, hard exoskeleton. The Great Barrier Reef is the single biggest system of corals in the world. It’s been in plenty of warm water in the last several decades for a huge number of corals being ruined to coral bleaching’.

Corals are an intersection of numerous different marine towns, but these animals themselves depend on algae to endure. Algae reside in their tissues having symbiotic relationships with corals. When corals undergo bleaching, warming ocean waters kill the algae in reefs. This cuts corals away from 90% of their energy source that the algae provide, turning them white. Whilst the corals are not dead when they are bleached it does sufficient damage that some of the reef architecture can never be replenished or recovered as it was earlier. In a study published researchers have shown that infant corals moving to a once bleached coral reef has fallen, by 89 percent, when compared to the past.
