The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). 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 labelled 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, dumping of dredging sludge and cyclic population outbreaks of the crown-of-thorns starfish.[10] 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 AUD$3 billion per year. In November 2014, Google launched Google Underwater Street View in 3D of the Great Barrier Reef.
A March 2016 report stated that coral bleaching was more widespread than previously thought, seriously affecting the northern parts of the reef as a result of warming ocean temperatures. In October 2016, Outside published an obituary for the reef; the article was criticized for being premature and hindering efforts to bolster the resilience of the reef. In March 2017, the journal Nature published a paper showing that huge sections of an 800-kilometre (500 mi) stretch in the northern part of the reef had died in the course of 2016 due to high water temperatures, an event that the authors put down to the effects of global climate change. The percentage of baby corals being born on the Great Barrier Reef dropped drastically in 2018 and scientists are describing it as the early stage of a "huge natural selection event unfolding". Many of the mature breeding adults died in the bleaching events of 2016-17 leading to low coral birth rates. The types of corals that reproduced also changed, leading to a "long-term reorganisation of the reef ecosystem if the...
Read moreVery natural and beautiful The Great Barrier Reef, located off the northeastern coast of Australia, is the world's largest coral reef system, stretching over 2,300 kilometers. Renowned for its stunning biodiversity, it comprises over 2,900 individual reefs and 900 islands. Home to a myriad of marine species, including colorful corals, fish, sharks, and turtles, the reef is a UNESCO World Heritage Site.
Unfortunately, the Great Barrier Reef faces numerous threats, primarily from climate change. Rising sea temperatures lead to coral bleaching, disrupting the delicate balance of the ecosystem. Human activities such as pollution, overfishing, and coastal development further exacerbate these challenges. Conservation efforts are underway to protect and preserve this natural wonder, including marine protected areas and sustainability initiatives. Despite ongoing concerns, the Great Barrier Reef remains a globally significant ecosystem, showcasing the importance of collective efforts to safeguard the planet's marine...
Read moreStretching for 2300 kilometres off the east coast of Australia, the Great Barrier Reef is one of nature's greatest marvels. It is officially the biggest structure made by living organisms and can be seen from even outer space!! Blessed with abundant marine flora and fauna, visitors are always enthralled by the sheer beauty of this unique ecosystem. Snorkelling and diving are some of the most popular activities here to get a first-hand experience of the marine life. Apart from the many reefs themselves, there are hundreds of tropical islands and golden sun-kissed beaches along the reef. These islands and beaches are the perfect setting for those who wish to take a break and bask under the sun. When you are looking for some time away from the beaches and the reef, take helicopter rides to truly experience the beauty of the region.
