Who cares about some Phillipino reefs, anyways? They've probably fished the *expletive deleted* thing out.
The reefs are an excellent source of tropical fish for the aquarium trade. They use cyanide to stun the fish, and then the cyanide settles on the reef and kills the coral.
Of course, if they can't afford the cyanide, they go the old fashioned route:
The coral reefs in the PI are probably in the worst shape of anywhere in the world.
