Australia’s Great Barrier Reef is currently experiencing its most severe bleaching event to date, according to the country’s reef authority. The Great Barrier Reef is known as the largest living structure in the world and is home to a wide range of coral and fish species. Aerial surveys conducted by scientists have revealed that around 730 out of the 1,000 reefs in the Great Barrier Reef have been affected by bleaching. This marks the fifth mass bleaching event in the past eight years. Bleaching occurs when coral expel microscopic algae, known as zooxanthellae, in order to survive. If the high temperatures continue, the coral can eventually turn white and die. Climate change is identified as the biggest threat to reefs worldwide. The Great Barrier Reef is an incredibly resilient ecosystem, but this summer has posed significant challenges. Experts warn that the recovery of the affected coral is uncertain. Despite investment in improving water quality, combating climate change, and protecting endangered species, the extent of the damage and future recovery remains uncertain.
