34. The Christmas Island Coral Reef

Christmas Island is unique for more than just having millions of crabs invade the island during its mating season, it also homes one of the world’s most beautiful coral reefs. At least it did up until recently. In just ten months between 2015 and 2016, the reef was nearly completely wiped out.

The reason behind this was stress due to the heat brought on by global warming. The coral reef was described as being a ghost town by a University of Victoria biologist. They went on a one month scuba diving expedition and concluded that El Nino had killed the coral reef.
