At over 2000 kilometers long The Great Barrier Reef is the largest living structure on Earth.
The reef is located in the Coral Sea, off the coast of Queensland, Australia.
The Great Barrier Reef can be seen from outer space and is the world’s biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labeled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland.
A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such as fishing and tourism. Other environmental pressures on the reef and its ecosystem include runoff, climate change accompanied by mass coral bleaching, and cyclic population outbreaks of the crown-of-thorns starfish. According to a study published in October 2012 by the Proceedings of the National Academy of Sciences, the reef has lost more than half its coral cover since 1985.
The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples, and is an important part of local groups’ cultures and spirituality. The reef is a very popular destination for tourists, especially in the Whitsunday Islands and Cairns regions. Tourism is an important economic activity for the region, generating over $3 billion per year.
In November 2014, Google launched Google Underwater Street View in 3D of the Great Barrier Reef.
]]>Two large kangaroos were filmed brutally battling it out in the suburbs of New South Wales, in a bouncy brawl lasting more than five minutes.
The incredible clip, filmed on the Central Coast, shows the two animals throwing vicious punches and using their long tails for support as they repeatedly kick each other.
The fight begins in the street, beside a parked car, but winds onto front lawns and into home driveways.
Who won? You be the judge.
