The great barrier reef is the world s large coral reef system [1] [2] with more than 2,900 individual keys [3] and 900 islands covering an area of approximately 344,400 square kilometers (133,000). It covers an area of 2,300 km (1,400 mm). ). [4] [5] The mat is located in the Coral Sea off the coast of Queensland, Australia. The Great coral reef are often seen from space and is that the largest single structure within the world made from living organisms. []] This rock structure is made up of billions of small animals and is made up of what is known as coral polyps. []] It supports the range of life and was selected as a World Heritage Site in 1981. [1] [2] In 1997, CNN named it one of the Seven Natural Wonders of the World. [8] The Australian World Heritage Site added it to its list in 2007. [9] The Queensland National Trust named him Queensland's state icon in 2006. [10]

A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps limit the effects of human use such as fishing and tourism. Environmental pressures on the reef and its ecosystem include runoff, large-scale coral bleaching with climate change, dumping of dredging mud, and the spread of starfish populations with crust-off thorns. [11] The reef has lost more than half of its coral since 1985, according to a study published in October study published by the National Academy of Sciences in October 2012. The study confirmed that more than half of the reef's coral was found. Lost between 1995 and 2017, with the effects of broader events related to the 2020 interval still lingering. [12] [13]

The Great Barrier Reef has been known and used by the people of ancient Australia and the Torres Street Islander, and is an important part of the cultures and spirituality of local groups.  Tourism is a major economic activity for the region, generating more than 3 3 billion annually. [14] In November 2014, Google launched Google Underwater Street View in 3D in the Great Barrier Reef. [15]

A March 2016 2016 report found that coral bleaching was more widespread than previously thought, with warmer ocean temperatures seriously affecting the northern part of the reef. In October 2016, published a written publication for out rocks; [17] The article was criticized for being premature and hindering efforts to promote reef flexibility. [18] In March 2017, the journal Nature published an article stating that large sections of the 800 km (500 mi) long section of the northern part of the reef had collapsed during 2016 due to water temperatures. Had broken, this incident was presented by the authors. Minimize the effects of global climate change. [19] Baby coral births on the Great Barrier Reef have dropped significantly in 2018, and scientists are calling it the beginning of a "huge natural selection event." Many mature adults have died in the 2016-17 bleaching incidents, which has reduced coral rates. The re-emerging types of coral have also changed, leading to long-term reorganization of the reef ecosystem "if this trend continues." "[20]

The Great Barrier Reef Marine Park Act 1975 (Section 54) requires an outlook report every five years on reef health, pressure and future. The last report was published in 2019. [21]
