The Great Barrier Reef, located on the eastern coast of the continent now generally referred to as “Australia,” first started forming sometime right around 25 million years ago. Throughout its long history it has continually been the biggest, or one of the biggest, living structures in the world — and has also been home to myriad numbers of other organisms and whole ecosystems.

This long life has seemingly been coming to an end over the last few decades, as a result of increasingly common and extensive bleaching events caused by warming seas (and other factors) and increasingly acidic waters.
