Importance of Estuaries

Estuaries are both a protective barrier and a filter. They prevent erosion and flooding inland. The sand bars dampen the impact of the waves while the shellfish and plants prevents the shore from washing away. The marshes and swamps take most of the wind and rain, it also helps hold onto water. The plants and fish help filter out the pollutants in the water.
