TAKKU: Why is it dark here?
RINO: The sea water is very muddy. We can’t see around well.
PRESENTER: Takku and Rino stared to see well in the dark and glazed sea. Then, they found chunks like whitish bones spreading endlessly at the bottom of the sea. All of a sudden, Uuta uttered a loud voice.
UUTA: Probably they are.....
MONET: Yes, that’s right. They are the same corals as what you have seen earlier.
PRESENTER: It was Dakuwaka who replied Takku’s question in a sad voice.
DAKUWAKA: These are dead corals.
TAKKU: Dakuwaka, why are they dead?
DAKUWAKA: Well, there are various reasons. Firstly, coastal mangroves were cut down and mountain soil and mud flowed down into the sea, and the soil and mud prevented the sunlight to reach the bottom of the sea. And so, corals are dead without the sunlight.
PRESENTER: This time, Rino asked a question.
RINO: But why the mangroves were cut down?
