The video tutorial explores marshes, a type of wetland, and their significance. It covers three types of marshes: salt marshes, freshwater tidal marshes, and freshwater marshes. Salt marshes are influenced by ocean tides and host specific plants and animals. Freshwater tidal marshes, while also tidal, do not contain saltwater and support a wider variety of life. Freshwater marshes are the most diverse and common in North America. Marshes play a crucial role in filtering pollution and reducing flooding but face threats from urban development and agriculture.
