The Great Barrier Reef is dying. As pollution and other man-made influences threaten the reef, which is not expected to survive past 2050, Australian scientists are taking measures to freeze the corals’ demise – literally. They hope to save the endangered species by freezing eggs and sperm from the coral, then fertilize and regrow the coral in the lab. As they enter the deep freeze, the Great Barrier Reef coral will become the latest in a large number of species stockpiled in cryogenic chambers in an attempt to reverse the advance towards extinction.
