Coastal wetlands are areas where land meets the ocean, characterized by the presence of saltwater or brackish water. These ecosystems include marshes, swamps, and estuaries, providing vital habitats for various plant and animal species. They play a crucial role in filtering pollutants, protecting shorelines from erosion, and supporting biodiversity. These wetlands are essential for many human activities, such as fishing and recreation. They also act as natural buffers against storms and rising sea levels, helping to mitigate the impacts of climate change. Protecting coastal wetlands is important for maintaining ecological balance and supporting local economies.
