You must have heard of the largest coral reef in the world- The Great Barrier Reef, but did you know that it is a threatened place? The turquoise blue water of this reef is home to some 1500 varieties of fish including some of the most amazing in the world. It covers an area of 1680 miles and is a spectacle to watch. Sadly, 50% of the reef has disappeared in the last 27 years due to global warming and coral bleaching. It is being estimated that the Great Barrier Reef would be irreversibly damaged by the year 2030.
