The helicopter pilot was flying just low enough over the Great Barrier Reef (GBR) in Australia for me to enjoy a good view of the area.
There are about 900 islets in the GBR, but the azure, glistening coral reefs were our main focus that day. This was the planet’s largest tropical coral reef system, a Unesco natural heritage site under full protection and preservation.
