Coastal wetlands are ecosystems that serve many valuable functions; they are important sources of food and fresh water.
They provide valuable services, including water treatment and erosion control. Wetlands filter water and provide habitat for a number of animal and plant species. They also serve as recreational areas for various outdoor activities. Wetlands comprise large extensions of coastal land and are highly valuable because they protect coastal land from flooding and damage caused by natural phenomena, such as hurricanes and storms.
