How the mangroves are affected by us?

We destroy them to make plain lands for the settlement, business, agriculture and aquaculture purposes.

[Strange! They themselves are providing us with good quantities of food fishes and other edible organisms. They also provide shelter for many juvenile food fish, shrimp, crab and other invertebrates. They maintain the fishery-balance so as to provide enough sea-protein for us. But what have we done to them? We have killed them with our greed, expecting more delicacies.]

We cut them for timber, fuel, charcoal and to make boats.

We are too generous and careless in dumping pollutants and wastes in the mangrove areas.
