We're heading to Florida today to Everglades National Park, the largest tropical wilderness in the United States. The park was established in 1947 to defend a fragile ecosystem and covers about 20% of the entire Everglades wetland. But even with the park service's protection, the Everglades' features, primarily shallow freshwater pools, have suffered significantly due to human activity.
