Episode 1

Florida: America's Animal Paradise

Florida is famous for its beaches, blue water and year round sun – but it also has a surprising wild side. It is home to pine forests, coral reefs and the famous Everglades wetland, the largest sub-tropical wilderness in the US. Here, manatees swim in crystal clear rivers, baby alligators practice their hunting skills and miniature deer roam free. Every year, this state faces the full forces of nature - from wildfires to flooding and powerful hurricanes. And today, a growing human population and a cast of animal invaders are threatening this wild paradise. With the help of pioneering scientists, will Florida’s wildlife continue to weather the storm?
