Wild ChroniclesSeason 3, Episode 31 of 42
News from Nature - With a combined mass surpassing that of all humans, krill is a dietary staple of many marine species. But overfishing threatens to endanger local populations of this marine manna in Antarctica. Wild Chronicles joins scientists from around the world as they research how changes in the Antarctic krill populations are affecting marine ecosystems. Stories from the Wild - In the Duba Plains of Botswana, National Geographic Explorers-in-Residence Dereck and Beverly Joubert begin another day filming a handful of the 20,000 lions left in the world. The couple has been capturing shots of bush animals for the past 27 years in central Africa's most remote camps and expansive plains. Battling seasonal floods, migratory crossings and malaria, the Jouberts aim to deliver a message of conservation as they bring viewers closer to the heart and soul of Africa. GeoCast - The Northwest Hawaiian Islands are under attack...by garbage. Few people have ever set foot on this remote archipelago, but human influence is still felt here as man-made debris regularly washes ashore, threatening to take over a place where wildlife has long reigned. On the Brazilian plains, two small farmers are paying it forward by passing on sustainable agriculture skills to other families. Recognized as National Geographic Emerging Explorers for their efforts, Cid Simoes and Paola Segura operate an Earth-friendly business that teaches rural farmers how to grow crops without depleting natural resources - and how to make a better profit while saving the planet at the same time. The Sahel is a region of cultural, geographic and religious divides - a vast North African area running across both arid and tropical climates. Turmoil here is deep, and the U.S. government is responding to its many conflicts. Images of the Sahel, born of harsh contrasts, show the slow strengthening of the region as schools are rebuilt and civil tensions move towards peace.
