The Florida Everglades represents a unique ecosystem not presently found anywhere else in the world. The subtropical wetland is the largest ecosystem in North America, a natural habitat for a diversity of species you won’t see anywhere else: countless aquatic birds; numerous endangered species such as the manatee, Florida panther, and American crocodile; and a slew of mammals that have been untouched other than by natural predators. It is the only place you’ll see an alligator and a crocodile in the same area. But at present, the Everglades faces many threats that could permanently change its landscape.
