Answer:

             Mangrove is a small tree that grows in coastal saline or brackish water in the tropics. They are among the planet’s best carbon scrubbers. The ecosystem created hosts a variety of species, including 174 species of marine megafauna. Mangrove swamps protect coastal areas from erosion, storm surge (especially during hurricanes), and tsunamis.

              Without mangroves we would all be diminished and many people would suffer. It’s a dismal scenario that includes coasts with barren, unproductive shores, collapsed fisheries, turbid, polluted water, little protection for communities from severe weather events and sea level rise and loss of many types of animals and plants. Losses of mangroves also release large amounts of carbon dioxide into the atmosphere, arising from destruction of their biomass and the release of the large carbon stocks held in their soils. This affects all of us on the planet as it contributes to global warming, further accelerating global climatic change.

                  We should restore mangroves not killing them. Without it, what will happen to us, to the world, especially those who live near the shores. That's why we have to protect mangrove swamps to prevent any loss in this world.
