This area of more than 2 million miles of marine landscape, the Coral Triangle is located in the western Pacific ocean and houses more than 75% of the world’s species of coral. This area is home to more than 600 species of live coral that build reefs, and 2,000 different types of reef fish. 

Since the 1950s, scientists have shown that the population of coral reefs has been cut in half, creating a dire situation for coral and other marine wildlife. Global climate change, pollution, overfishing, coral mining and other human activities have been the main culprits for the destruction of this important landscape of the ocean.

Coral Triangle Day is here to bring light to the need for everyone, all over the world, to pay more attention and support efforts to help save this amazing area of biodiversity.

History of Coral Triangle Day

The inaugural celebration of Coral Triangle Day took place in 2012 when it was founded through the efforts of the Coral Triangle Initiative on Coral Reefs, Fisheries, and Food Security (CTI-CFF). The event was purposefully set to take place one day after World Oceans Day to add impactful attention around the need to preserve and care for the world’s center for marine biodiversity. Coral Triangle Day is also part of a larger campaign called Oceans Need Action, which encourages those involved in the Coral Triangle region to address the issues of threats caused by humans.
