We have navigated on The Great Barrier Reef

We have been on the boat and person told us the story of The Great Barrier Reef : 

The Great Barrier Reef is threatened by Global warming and the development of fossil fuels. The water temperature increases and makes huge bleaching on the reef corals bleached by 93% and killed for 22%. The north part is the most attacked. This is the longest ecosystem of the world, it does 2.300 kms long.  

The divers used to go snorkeling among turtles and color fishes.

We have been snorkeling too and we have seen the corals and a lot of marine animals...We have found this place very beautiful but all people have to pay attention because it is in real danger

This place is in the UNESCO world heritage since 1981.
