Marisma

The video tutorial explores marshes, a type of wetland, and their significance. It describes three types of marshes: saltwater, freshwater tidal, and freshwater marshes, highlighting their unique characteristics, flora, and fauna. Saltwater marshes are influenced by ocean tides and host limited plant life but diverse animal species. Freshwater tidal marshes, though also affected by tides, lack saltwater, supporting more biodiversity. Freshwater marshes, the most diverse, are not connected to the ocean and are common in North America. Marshes play a crucial role in filtering pollution and reducing flooding, but many have been destroyed for urban development and agriculture.
