Drivers, managers and team owners live life in the fast lane — both on and off the track — during this cutthroat new season of Formula 1 racing.
In the first episode, the 2021 Formula 1 season begins at the Bahrain Grand Prix, where drivers give it everything to take the first checkered flag of the year.

We routinely talk about healthy food and clean water, but how often do we spare a thought for what enters our lungs? The World Health Organization calls air pollution the silent killer. Air pollution is proven to shorten our lifetimes and it hits the vulnerable - children, the sick and the elderly - hardest of all.
Prince William, Sir David Attenborough and astronaut Naoko Yamazaki hear the personal stories of people who are directly affected by air pollution and show us incredible solutions.

David Attenborough takes a stark look at the facts surrounding Climate Change in today's world, detailing the dangers we are already having to deal with and future threats, but also the possibilities for potential solutions to this global threat and the radical political, social and cultural changes needed.
Interviews with some of the world’s leading climate scientists explore recent extreme weather conditions such as unprecedented storms and catastrophic wildfires. They also reveal what dangerous levels of climate change could mean for both human populations and the natural world in the future.

Today, the topic of climate change is a major part of daily life, yet 40 years ago it was virtually unheard of. Since then, Horizon have followed scientists as they have tried to unpick how the climate works and whether it is changing. Dr Helen Czerski delves into this unique archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history. It has been a constantly surprising journey of discovery that has revolutionised our understanding of climate, and seen scientists face unprecedented controversy and criticism.

Jeremy's restaurant opens in a matter of days, but it's all on the QT. Jeremy does not want the council to find out until just before it opens. Which is why Jeremy and Kaleb are laying pipes for water and electrics across a field in the dead of night. Pepper the heifer is still very much alive and is enjoying the company of Break Heart Maestro a lot.
Two days until Restaurant Opening Day, Jeremy informs the council and it's game on: Alan and his team of builders work at full throttle, Pip and her team of chefs do too, and the blend of excitement and panic is affecting everyone. The day itself arrives. Will the Diddly Squat Farm Restaurant sink or swim? Or will the council shut it down before the first steak hits the grill?

Every year, over a thousand climbers try to reach the summit of Mount Everest, with the annual record for successful attempts currently standing at 633. But of that number, nearly half were Sherpas - the mountain's unsung heroes. Yet the Sherpa community has remained secretive about their nation, culture and experiences living in the shadow of the world's highest mountain. Now, for the first time, they open the door into their world. Without the expertise of the Sherpas, only the hardiest and most skilful climbers would succeed. Every day they risk their lives for the safety of others, yet they seek neither glory nor reward, preferring to stay in the background. Following the stories of four such Sherpas - Phurba, Ngima, Ngima Tenji and Gelu - this film reveals the reality of their daily lives, not just up the mountain, but with their families after they return home.
