A jaguar fights to keep his river home in Brazil as the night brings both challenges and opportunities to hunt. Evening is falling in the world's greatest tropical wetland, Brazil's Pantanal. A stronghold for South America's most secretive big cat, the jaguar. And enjoying the last warmth of the day is a male known as Juru. At six years old and weighing over 100 kilos, he's amongst the largest, most powerful big cats in the Americas. This prime stretch of river has been his territory for two years. But tonight Juru's reign hangs in the balance. In a recent fight with a rival male, he badly injured his paw. It's left him weak and hungry. The coming days and nights will test him more than ever before. He'll need to summon the strength to defend his river.

For Charley Boorman and Ewan McGregor, their journey in the smooth Ecuadorian roads would most definitely have come as a relief after some rough terrain riding. Next up, they stop by one of the factories that make the famed Panama hats. One of the local producers explains that making them by hand takes roughly up to a month. At the other end, the crew on the Rivians make a dash for Central America where they have to ferry their trucks across as the Darién Gap blocks their path. On their way, they make a quick pitstop at one of the cacao factories to know more about cocoa production, one of the economic drivers of the country.

With a million species at risk of extinction, Sir David Attenborough explores how this crisis of biodiversity has consequences for us all, threatening food and water security, undermining our ability to control our climate and even putting us at greater risk of pandemic diseases.
Everything in the natural world is connected in networks that support the whole of life on earth, and we are losing many of the benefits that nature provides to us. The loss of insects is threatening the pollination of crops, while the loss of biodiversity in the soil also threatens plants growth.
Last year, a UN report identified the key drivers of biodiversity loss, including overfishing, climate change and pollution. But the single biggest driver of biodiversity loss is the destruction of natural habitats. Seventy-five per cent of Earth's land surface (where not covered by ice) has been changed by humans, much of it for agriculture, and as consumers we may unwittingly be contributing towards the loss of species through what we buy in the supermarket. Human activities like the trade in animals and the destruction of habitats drive the emergence of diseases. Disease ecologists believe that if we continue on this pathway, this year’s pandemic will not be a one-off event.

The film tells the story of the ill-fated Nazi Land Speed record attempts. This is a story of engineering excellence, Grand Prix racing, Nazi propaganda, celebrity, and an intense rivalry which would leave a speed record unbroken for 79 years and one of Nazi Germany's best racing drivers dead. During the rise of the Third Reich two German car manufacturers were ordered to build the most high performance vehicles the world had ever seen. What followed was a rivalry that would reap Grand Prix victories, international domination that was a propaganda coup, and provide world fame to its drivers who risked their lives smashing speed records that would stand for 79 years. All under the direct orders of the Fuhrer himself.
Bugatti and Alfa Romeo dominated racing before 1934. But the years from 1934 to 1939 were six tumultuous years in which Grand Prix racing was dominated by the German Auto Union, the arranged marriage of Audi, Horch, Wanderer, and DKW, and Mercedes-Benz teams and provided a spectacle of speed, sound and fury never previously attained and never since matched. There are few periods of racing that have excited as much interest, event attendance and sophistication of equipment as the era of the Silver Cars. They were so far ahead of their time that many of their accomplishments were not duplicated until Mercedes went racing again in the early 1950s. There is also something about men who faced the challenges of staying in a cockpit of a highly sophisticated machine capable of 200 mph with no safety systems. They were giants and among them were Italian Tazio Nuvolari and two greatest German pilots of the thirties, Rudolf Caracciola of Mercedes and Auto Union's Bernd Rosemeyer who duelled with faster, more innovative and sleeker machines, developed in wind tunnels.
This special documentary charts the rise of Nazi Germany's dominate 'Silver Arrow' Grand Prix and Speed Record cars of the 1930's. Leading motor racing and World War 2 experts James Holland, Richard Williams, Eberhard Reuss and Chris Routledge tell the story of the Nazi funded Auto Union and Mercedes Benz 'National Racing Cars'. Hitler's Supercars interweaves the rise of the Third Reich with the racing exploits it funded and what propaganda messages these racing cars where sending.

'Speed' investigates mankind's insatiable necessity to move faster and further; for pleasure, for work, to explore, to survive. From ancient outriggers, to modern bullet trains, to the interplanetary travel of tomorrow; This series is a thrilling joyride through the Science and History of travel.
'Across Continents:' Never in the history of humanity have so many of us been mobile, never has our demand for fast, efficient and safe transportation been so high, and never have we relied so heavily on technology to deliver. New innovations propel us into the world of self-driving cars and ultra high-speed trains.

For most of our history, we humans considered ourselves unique. But now, a new, artificial species might challenge our superiority. Mechanical beings have the potential to change everything. How we got them is a story of astonishing twists and amazing turns to achieve us the machine that may turn out to be the most revolutionary technology ever conceived--the robot.
Learn how robots were first conceptualized in ancient Rome and see how their use has evolved over the centuries, from the calculator to the Mars Lander. Then, take a sneak peek at what future robots will be able to do. Narrated by Patrick Stewart.
