"River of Grass" is a term often used to describe the Everglades, a vast wetland ecosystem located in southern Florida. This unique area is characterized by slow-moving water flowing through sawgrass marshes, creating a habitat for diverse wildlife, including alligators, wading birds, and various fish species. The Everglades is recognized for its ecological significance and is a UNESCO World Heritage Site. The term was popularized by author Marjory Stoneman Douglas in her 1947 book titled "The Everglades: River of Grass." Douglas's work highlighted the importance of preserving this fragile environment and raised awareness about the threats it faces from urban development and pollution. Her advocacy played a crucial role in the conservation efforts for the Everglades.
