What’s the largest living structure on Earth? It is of course the Great Barrier Reef, composed of over 2,900 individual reefs and 900 islands reaching out for over 2,600 kilometers (1,600 miles) over an area of approximately 344,400 square kilometers (133,000 sq miles). The reef is located in the Coral Sea, off the coast of Queensland in north-east Australia. It is the product of billions of tiny organisms called polyps which squirt calcium carbonate during photosynthesis to form coral. Soft corals adhere to hard corals, algae and sponges coat the rocks, and every fissure is a creature's home. But this delicate coral colony is beginning to disintegrate, worn out by the effects of climate change, pollution and manmade disasters.
