In the boreal forests of Europe, a young brown bear clashes with wolves and tries to find a mate beneath the stars. On the edge of the Arctic Circle, lies an enchanted wilderness. In Europe's boreal forest, It's so far north that in winter, nights can last 20 hours. This woodland is home to a population of secretive bears that lives most of their lives in the dark. But now, using low-light cameras we can see their nighttime world as if it were day.

The last episode examines the fragile interdependence that exists between forests' wide variety of residents, including bald eagles, hunting dogs and Siberian tigers.
Over half of all the world's trees, evergreen and deciduous, stand in great assemblies. For many of us, they are places of mystery and darkness. They are key to our climate, and home to countless unique species. The boreal forest contains 750 billion trees, and it stores over 40 percent of the world's carbon, making it a vital element in the fight against climate change. In the past, we have destroyed them without hesitation. Yet, forests do have an astonishing ability to recover. If we choose to give forests time and space, they could reclothe the earth with much of the rich and varied communities of animals and plants of which we have, so recently, robbed it. A future with more forests is key to the resilience of our planet.

Nancy Silverton describes her life path involving both Los Angeles and Italy, her family and her obsession with bread. She was born in Sherman Oaks, CA in a family where going out to eat was considered a special treat. But when she entered college and found herself 'very attracted by a handsome man' who worked in a kitchen, she landed herself a job and a new passion.
These details, which all lead up to her stint at Wolfgang Puck’s celebrated LA restaurant Spago in 1982, are intercut with present-day scenes of Silverton working at Osteria Mozza.

What would happen if you ate nothing but fast food for an entire month? Filmmaker Morgan Spurlock does just that and embarks on the most perilous journey of his life. The rules? For 30 days he can't eat or drink anything that isn't on McDonald's menu; he must wolf three squares a day; he must consume everything on the menu at least once and supersize his meal if asked.
Spurlock also treks across the country interviewing a host of experts on fast food and an equal number of regular folk while chowing down at the Golden Arches. Spurlock's gruelling drive-through diet spirals him into a physical and emotional metamorphosis. Find out in 'Super Size Me' a look at the legal, financial and physical costs of America's hunger for fast food.

Every year grizzly bear families in North America depend for their survival on a spectacular natural event: the return of hundreds of millions of salmon from the Pacific Ocean to the mountain streams where they were born. The salmon travel thousands of miles to spawn and then die. The great run not only provides food for bears, but for killer whales, wolves, bald eagles, and even the forest itself. The question is: will the salmon return in time to keep hungry bears alive?
A mother grizzly and her cubs emerge from their den high in snowy Alaskan mountains. Filming from the air the team capture a TV first, following the bears as they negotiate a near vertical slope on their journey to the coast where they await the return of the salmon. Meanwhile, the salmon are making their way to the to river mouths where they must swim upstream and against the current. The programme reveals how they tackle the torrents and leap over waterfalls, a feat equivalent to a human jumping over a house. Dozens of hungry bears eagerly await the salmon that make it up river. In another TV first, underwater cameras record the ingenuity and fancy footwork they use to collect dead salmon from the bottom of deep pools.

The sixth and last episode of the series follows photographer Art Wolfe as he documents the world's cultures, including the Surma of Ethiopia and the masked mud men and Huli clans of Papua, New Guinea.
