What is the Great Barrier Reef?

What is the Great Barrier Reef? Thanks for asking! The Great Barrier Reef is planet Earth’s largest living structure. It has remarkably rich biodiversity, but is gradually disappearing due to pollution caused by humans. Tourists have been absent from the reef since the beginning of the Covid-19 pandemic. But paradoxically, this isn’t likely to help the situation. The reef is located in the sea off the coast of North-East Australian territory Queensland. Its surface area is larger than that of Italy and it can even be seen from space! In some places the corals can be found several miles underwater; in others just under the surface. According to the Great Barrier Reef Marine Park Authority, the diverse Reef ecosystem is home to 1625 species of fish, including 1400 coral reef species. Then you’ve got over 3000 species of molluscs, 630 species of echinoderm, 14 breeding species of sea snakes, 215 species of birds, six species of marine turtles, 30 species of whales and dolphins, 133 species of sharks and rays, and much more. Among them are many vulnerable and endangered species. Well it sounds like they won’t be there for much longer, if the situation is as bad as I understand? Indeed, the Great Barrier Reef is under threat. It’s estimated that up to half the corals have disappeared in the last few years. One of the biggest dangers to the reef is the crown-of-thorns starfish, which feeds on coral and has few predators. So why are they suddenly invading the Barrier Reef? And what about the tourism?
