The Great Barrier Reef is special because it is by far the largest reef in the world. It is consisted of around 2,900 individual reefs. The size of this reef is approximately as the size of Germany. There are over 900 islands that are stretched over 2,600 km along the the reef. The Great Barrier Reef is so marking and big, that even though it is below water it can actually be seen from space. The ecological importance of this reef is enormous as it is a home for thousands of species, with approximately 10% of all fish species in the world living in it. Because of its beauty and numerous attractions, the Great Barrier Reef is one of the most visited tourist destinations, and the Australian economy manages to generate between 5 and 6 billion Australian Dollars annually from it. Unfortunately, all of the human activity has been affecting this reef very negatively, and little by little part of it is dying out.
 
        
             
        
        
        
Ensuring the safety of the people after the earthquake struck would be the main priority. Make sure there would be no occurrence of tsunami before deploying rescue operations. I would immediately deploy all of the necessary health equipment and personnel to the affected areas. Rescue operations must be started also to save those who were trapped by debris. Also the removal of live electrical wires is really important.
