Malé (Maldives) (CNN)Alongside the famed Great Barrier Reef, the Maldives is also home to some of the most enchanting and diverse coral reefs in the world, its crystal clear waters bursting with color and life.
Can the Maldives save its coral reefs?
However, since 2014 this tropical paradise has been struck by severe coral bleaching, affecting between 60 percent and 90 percent of its coral, depending on the area.
Corals become bleached when under stress because of changing conditions, such as rising sea water temperature. This causes the coral to expel the algae living in its tissues, turning white.
The coral is not dead, but it is starving, as the algae provide up to 80 percent of its nutrients. Prolonged higher temperatures can kill the corals completely, with a cascade of negative effects on the many species that depend on them, including the human communities that they support.
Bleaching episodes typically last one year, but the most recent has been going since 2014. Australia's Great Barrier Reef has also been affected, with more than two thirds of it experiencing "shocking" amounts of bleaching.
"In 2014 reefs around the world were hit with one of the worst coral bleaching events on record", said Thomas le Berre, a French coastal oceanographer who is responsible for some of the top environmental projects in the Maldives.
The previously vibrant corals, which help attract over one million tourists a year to the archipelago, have turned into a ghostly shadow of their former self.
Le Berre says part of the blame goes to El Niño, a cyclical weather event that takes place every few years resulting in warmer waters passing through the Pacific and Indian Ocean. Combined with global warming, it has seen water temperature reach new highs of 34 degrees in some area, causing the corals to go beyond their thermal limit, which results in bleaching and sometimes death.
