In ideal conditions, another process known as accretion should replace the displaced land by the same amount of sediment eroded from other areas. Lately, the erosion across the country has been worsening because of the rampant cutting of mangrove trees, which serve as natural protection for coastal areas. The plant is also known for its role in assisting the accretion process by trapping sediment; therefore, its absence has been preventing sedimentation from occurring. Acknowledging that re...
