At the heart of the US-Canada border sit The Great Lakes - the world's largest freshwater ecosystem, containing as much as one fifth of the planet's supply. Chapter 1: Source to Sea The water's journey from source to sea spans half a continent - 2,000 miles - and takes more than three centuries to complete. This first of three documentaries charts the feature and its surrounding flora and fauna, showing how beavers, wolves, loons, moose help shape this incredibly vast watershed. Chapter 2: The Big Freeze s winter descends on The Great Lakes, life must contend with the return of the ice that carved this immense watershed thousands of year ago. A polar vortex paralyses fish and ducks and attracts hundreds of bald eagles. Wolves hunt deer trapped by ice, but are manipulated by ravens. Chapter 3: Marvels and Mysteries The spring thaw in America's Great Lakes creates ice tsunamis. Photosynthetic salamanders, fishing wolves, deep-diving moose, baby rattlesnakes and colourful fish hunting mid-air all illustrate unique adaptations to to the warmer, brighter season.

Across the dunes of the Kalahari, a towering, 200-year-old tree extends its branches to the heavens. This camel thorn Acacia is a secret refuge for those in the know. Colonies of sociable weavers use its branches for their oversized nests. Oryx, kudu, and other herbivores feed on her ripened pods, helping soften the seeds for germination. As the rainy season descends, its branches become draped with golden flowers, a magnet for pollinating insects. For many, the Acacia is a 'tree of life.' It's a relationship as old as the Kalahari itself.

The endearing pangolin is a little-known scaly mammal. Found in Africa and Asia, these shy creatures have an unfortunate tagline - they are the most poached and illegally trafficked animals in the world. Based in Namibia, conservationist Maria Diekmann rescues and rehabilitates her local pangolins. In a bid to better understand the global issues they are facing, we follow Maria to Vietnam, Thailand and China into the very heart of the crisis, where demand for pangolin products is greatest. In what turns out to be an emotional journey, Maria joins forces with a Chinese megastar to build a campaign to bring awareness to the plight of an animal most people have never even heard of.

The Okavango Delta is one of the world's largest inland deltas - and supports a variety of life as rich as any you will see in Africa. Yet this lush wetland of islands and lagoons lies in the middle of the vast, featureless Kalahari Desert. This is the story of how it happens. Following groups of wildlife, including hippos, baboons, catfish, kingfishers, leopards, warthogs and elephants, the film reveals how the yearly flood transforms the landscape and impacts their lives. But more surprisingly, it reveals how, with the help of termites and hippos, the flood actually creates this extraordinary delta in the first place.
