The Everglades is a diverse ecosystem located in South Florida, but urbanization has created significant impacts that have altered the physical landscape of the region, resulting in a symbiotic between humans and nature. Based on geographic research, the original Everglades covered an area of ​​approximately 12,000 km2, and now, due to urbanization and agricultural growth in this subregion, the area of ​​the Everglades has been reduced to half its original size (Willard et al 1-2 ). The Everglades is actually a subregion of the southern coastal region of the United States. It is composed of a unique climate, divided into sub-provinces that create a diverse range of environments in which wildlife can thrive, but the impact of human modifications over decades has dramatically affected animal populations and changed the functionality and the physical landscape of its expanse. Despite differences in urbanization and wildlife, major cities and the Everglades ecosystem thrive and blend together to form the ever-changing landscape of the modern Everglades. The Everglades may also be known as the River of Grass due to its 80.5 kilometers (50 mi) wide circumference and 161 kilometers (100 mi) long span, with the source of fresh water coming from the lake Okeechobee just north (Tramontana and Johnson 1-2). The Everglades then continues to flow through southernmost sandbars, mangrove islands, and the Florida Keys before emptying into Florida Bay. This route creates a mix of salt, brackish and fresh waterways that include the marshes and marshes of this unique environment (Tramontana and Johnson 1-2).
