Great Barrier Reef Decline Analysis

Introduction The causes for the Great Barrier Reef decline in Australia has been affected by natural and human faults. The natural effects of the decline are; water temperature changes, movements of the Earth’s crust (tectonic plates) and the new spreads of coral disease (1). As well as the anthropogenic stress, spotted on marine debris pollution, radiation and overpopulation (4). To understand the causes of species, decline better in the Great Barrier Reef, this research will be a case study method analysis from different scientist perspectives to respond and supply an updated research on the Great Barrier Reef decline over-time. Moreover, the objective of this research is to attract the reader’s compassion and comprehension of what has …show more content…
About fifty-eight percent of the world’s reefs are potentially threatened by human activity - ranging from coastal development and destructive marine pollution. Scattered pieces of rubbish or remains or marine debris it’s known as the most dangerous hazard for marine ecosystem due to the unawareness of humans, our rubbish goes straight to the ocean coming from mostly animal agriculture, industries and tourism (6). According to the book “Threats to the Reef”, marine debris in developed areas, most debris comes from the land — rain and wind washes litter left by people into storm water drains or waterways. In less populated areas debris is transported on ocean currents from domestic and international sources, either accidentally washed or blown overboard of a vessel or intentionally dumped. Plastic is the most common type of marine debris found on beaches in the Great Barrier Reef and worldwide — it makes up between 50 to 90 per cent of all debris items recorded. Plastic does not decompose or break down, it only breaks up into smaller pieces. In fact, a single plastic bottle can break up into more than 10,000 pieces of micro plastic (11). Moreover, to the anthropogenic causes of the Great Barrier Reef decline another cause is radiation. Threats like hot-water discharges from power …show more content…
Due to the natural and human grounds, the Great Barrier Reef Committee kept the Great Barrier as a protected Park Authority later in 1988 after continuous studies leading to a human catastrophe’s event from oil drilling in 1927 that killed many species. Mining was banned and the remarkable biodiversity of the Great Barrier Reef and will be a concern to protect it forever (5). Furthermore, in April 2015, marine debris was removed along the Capricorn Coast helping reduce debris at the Great Barrier reef by local Livingstone Shire Council staff, local businesses and volunteers that joined together and removed 5.43 tons of debris. Volunteers covered more than 17 kilometers of coastline collecting fragmented hard plastics, rope, nets, boat hulls and tires. Later on in May 2015, the Gladstone Local Marino Advisory Group invited aspiring local video makers to capture the issue of marine debris. Followed by raising awareness activities about marine debris in September 2015. Then in October 2015, Reef Guardian School Future Leaders Eco Challenge focused on collecting more than 11.68 tons of debris from the Great Barrier Reef coastlines. (11) . The scientist, James Woodford gave a theoretical solution to solve radiation at the Great Barrier Reef stating, “For decades, scientists and conservationists have been warning that
