The Great Barrier Reef survived five near-death events for more than 30 millennia

An international study that explored the evolution of the Great Barrier Reef in Australia revealed that the world's largest reef system has suffered up to five near-death experiences in the past 30,000 years.

During this period, the reef witnessed all kinds of problems such as abrupt changes in the environment, increase and decrease in sea levels and badociated temperatures, and an increase in sediments.

Although all these problems threatened the reef, the 10-year study revealed that it remained more resistant to environmental changes than previously thought and highly sensitive to sedimentary changes and water quality.
