What are facts about lagoons?

Lagoons are shallow bodies of water separated from larger bodies of water, such as oceans or seas, by barriers like sandbars, coral reefs, or islands. They often have brackish water, which is a mix of fresh and saltwater, supporting diverse ecosystems and wildlife. Lagoons can be found along Coastlines worldwide and play crucial roles in coastal protection, water filtration, and providing habitat for numerous species, including fish and migratory birds. Additionally, they are important for human activities such as fishing, tourism, and recreation.
