Millions of years ago huge forces ripped apart the Earth's crust creating seven spectacular continents. Over time, each continent developed its own remarkable wildlife.From the depths of the South American jungles to the frozen peaks of Asia, and from the cities of Europe to the vast plains of Africa - Seven Worlds, One Planet features extraordinary animal behaviour and untold wildlife stories from each continent. We discover how our seven worlds gave rise to the great diversity of life on Earth today, and reveal the challenges now faced by animals in a world shaped by us.SPECIAL FEATURESHighs and Lows of Wildlife Filmmaking McMurdo - Would you dive below the Antarctic ice?
