Day 24

The Great barrier Reef:
   Stretching 2,300 kilometres along two-thirds of the Queensland coast, is enormous;
It’s the only living structure in the world that can be seen from space;
Home to about 1/3 of the world’s coral and nearly 5,000 marine and mammal species;
In 2012 Google launched the very first underwater ‘Street View’ on the Great Barrier Reef.
