Interplays between humans and wildlife are often problematic in the Florida Keys. For example, although it is harmful, people commonly provide drinking water to federally protected manatees in order to get close to the gentle marine mammals.

Meanwhile, exotic iguanas are a major pest to local property owners, especially gardeners.
