Anon25 [30]

The mangroves trees help in holding the soil in place, they help in absorbing the energy of waves, and they help in filtering water and better the quality of it.  

Mangroves are a kind of estuarine or coastal wetland, featured by the existence of salt amended shrubs and trees, which develops beside the coast in subtropical or tropical latitudes all around the world. Several of the mangroves forests can be determined by their dense tangle of prop roots, which make the trees seem to be standing on stilts above the water.  

The mangroves safeguard the shorelines from destructing hurricane, storms, winds, and floods. They help in inhibiting erosion by stabilizing the sediments with their tangled root infrastructure. They sustain the clarity and quality of water, trapping the sediments and filtering pollutants arising from land.
