Great Barrier Reef Showing Signs of Recovery

Stretching more than 1,430 miles along Queenland’s coastline, the Great Barrier Reef is the longest coral reef in the world.

The Great Barrier Reef is big. Some parts of it died during the 2014-2017 bleaching events…

Coral bleaching occurs when coral experiences stress from heightened water temperatures or poor water quality.

In response, the coral ejects a photosynthetic algae called zooxanthellae, which removes the coral’s distinctive color.

If the stress conditions persist, the coral will die, the report says, but if conditions return to acceptable levels, some coral can reabsorb the substance and recover…

Some parts started recovering in the past few winter months…

The majority coral colonies on the inshore reefs have regained their color.
