Brazil's Emerald Oasis

Brazil's massive Pantanal is a land of extreme contrasts, ruled by dramatic cycles of torrential rain and arid heat. At the peak of the dry season, the floodplains bake and a searing struggle for life begins. However, there is an oasis that stubbornly refuses to disappear, a mysterious place that serves as a sanctuary for a host of animals and a hunting ground for predators. This is the story of Rebel Lake, where secretive tapirs bathe, wading birds take their pick of the fish-filled pools, and mighty jaguars hungrily prowl its banks.
