Video: People of the coral triangleThe Guardian
James Morgan of the WWF travels to the coral triangle – a 1.6bn acre stretch in south-east Asia that is the most biodiverse marine ecosystem in the world.
There he finds the Balau Laut, one of the last nomadic marine communities in the world, having their way of life threatened. This and depleting fish stocks is driving them to destructive fishing techniques, such as using dynamite and cyanide, maiming and killing Bajau fishermen and taking the world's epicentre of coral diversity to the point of almost irreversible damage
