Answer

  1. The Great Barrier Reef is one of UNESCO's World Heritage Sites and is the world's largest living structure, consisting of a vast collection of coral reefs.
  2. The Great Barrier Reef contains the largest collection of coral reefs, as well as 1,500 species of fish and 4,000 types of mollusks.
  3. Corals are actually a colony of thousands of very small invertebrate animals living very close together.
  4. In 2016, the Great Barrier Reef experienced severe coral bleaching, affecting two-thirds of the reef, particularly in the northern regions.
  5. Coral bleaches when water temperatures are a couple of degrees above the normal summer maximum for longer than two weeks.
  6. Besides coral bleaching, poor water quality and coastal development are identified as serious threats to the health of the reef. Additionally, tropical cyclones, like Cyclone Debbie in 2017, can physically damage parts of the coral reef.
  7. Scientists are tracking water temperature using satellite data to predict future coral bleaching. They share this information with experts in the Australian government to better understand and combat the effects of climate change on the Great Barrier Reef.
  8. The aims of UNESCO's 'in-danger' list are to inform the international community about the conditions threatening a natural wonder, such as the Great Barrier Reef, and to encourage governments to take action to protect the site.
  9. The Reef 2050 Long-Term Sustainability Plan is a plan released by the Australian government in response to UNESCO's concerns about the Great Barrier Reef. The plan, launched in March 2015, aims to protect the reef until 2050. The government is investing approximately $200 million over five years to ensure the improvement and preservation of the Great Barrier Reef for future generations.
