2. The “Underwater Amazon”

Up until recently, the coral reefs off of the Indonesian coast of Raja Ampat, known as the “Underwater Amazon” were regarded as some of the most spectacular reefs the world had to offer. But that all changed in the most devastating way in 2017.

In March of that year, a British cruise ship accidentally crashed into the Underwater Amazon when it veered off of its usual route. The crash caused 1,600 square meters of the reef to be damaged. Experts say that it could take 100 years for the reef to rebuild, so it could be a while before anyone can take a tour of this breathtaking reef in all its pre-impact glory.
