This is when the industrial revolution started. The industrial revolution is a major event because that is when machines are introduced. This then lead to further machines and other technologies being produced, which contributes to the production of carbon dioxide that causes the corals to bleach. - 1760 (Encyclopaedia Britannica, 2017)

This is when The Great Barrier Reef was discovered by Captain James Cook. This is a major event because The Great Barrier Reef is the world's largest living coral reef system and is being polluted. - 1770 (Science NetLinks, 2017)

The Great Barrier Reef National Park was established. The park protects the Great Barrier Reef and organises the place for tourists. It has been protecting the reef system till this day. - 1975 (Great Barrier Reef Marine Park Authority, 2017)

This is when the first mass coral bleaching was recorded. It happened to the coral reefs around the world. Affecting the Caribbean seas, the far eastern Pacific oceans and the Great Barrier Reef. This also drew attention to the association between ocean temperature and bleaching. - early 1980's (John Veron, 2013)

This was another massive coral bleaching event. The area of this mass bleaching event was huge. It affected reefs in over 50 different countries throughout the Pacific and Indian Oceans, the Red Sea and the Caribbean oceans. - 1997/1998 (John Veron, 2013)

This was the 3rd mass coral bleaching event recorded. This time it affected a huge area again. Scientists have also found the connection between the increase in ocean water's temperature due to the El Nino. El Nino is one of the main reasons for the cause of the mass coral bleaching. Most mass coral bleaching affects many countries due to the El Nino. - 2001/2002 (John Veron, 2013)

This was another mass coral bleaching event. This year was a lot more special because it actually wasn't an El Nino year but there were still heaps of corals bleached. This made the scientist realise that us humans are polluting the ocean way too much and combined with global warming, coral bleaching isn't going to stop anytime soon. - 2006 (John Veron, 2013)
