The Great Barrier Reef is the world's largest coral reef system, spanning approximately how many miles in the Coral Sea, off the coast of Queensland?

Made of more than 2,900 individual reefs and 900 islands, the Great Barrier Reef is the world's biggest of its kind and stretches over 1,400 miles off the coast of Queensland. As if that wasn't impressive enough, this natural wonder can actually be seen from outer space and is the world's largest single structure made by living organisms.
