The Coral Triangle is a 6 million square kilometer region that spans across 6 countries in south-east Asia and the Pacific, covering regions that are home to more than 500 coral reef species. It contains more coral reef species than any other place on the planet.Home to 76% (605) of the world's coral reef species and 37% (2,228) of the world's coral reef fish species, the Coral Triangle is the most biodiverse marine ecosystem on Earth and is known to directly support 120 million people that inhabit coastal regions throughout the area.

However, with the rapid expansion of human populations throughout the region along with coastal development, there is higher demand for fish (both to eat and to keep as pets) and more strain being put on this ancient ecosystem from increasing activity and pollution that both severely disrupts and permanently damages it.
