Ironically, during this same period, mangroves have disappeared with alarming speed. Hundreds of thousands of acres of lush wetlands have been cleared to make room for artificial ponds that are densely stocked with shrimp. Coastal wetlands protect the shoreline from erosion by acting as a buffer against wave action as in the case of coastal mangroves. Mangroves slow the tidal movement of water, allowing sediment to be deposited as the tide comes in so they build their own environment.
