The documentary series reveals the extraordinary riches and wonders of the Polar Regions that have kept people visiting them for thousands of years. Today, their survival relies on a combination of ancient wisdom and cutting-edge science. Most Arctic people live in Siberia, either in cities like Norilsk - the coldest city on earth - or out on the tundra, where tribes like the Dogan survive by herding reindeer, using them to drag their homes behind them. On the coast, traditional people still hunt walrus from open boats - it is dangerous work, but one big walrus will feed a family for weeks. Settlers are drawn to the Arctic by its abundant minerals; the Danish Armed Forces maintain their claim to Greenland's mineral wealth with an epic dog sled patrol, covering 2,000 miles through the winter. Above, the spectacular northern lights can disrupt power supplies so scientists monitor it constantly, firing rockets into it to release a cloud of glowing smoke 100 kilometres high. In contrast, Antarctica is so remote and cold that it was only a century ago that the first people explored the continent. Captain Scott's hut still stands as a memorial to these men. Science is now the only significant human activity allowed; robot submarines are sent deep beneath the ice in search of new life-forms, which may also be found in a labyrinth of ice caves high up on an active volcano. Above, colossal balloons are launched into the purest air on earth to detect cosmic rays. At the South Pole there is a research base designed to withstand the world's most extreme winters. Cut off from the outside world for six months, the base is totally self-sufficient, even boasting a greenhouse.

In this episode, Chris Packham tells the almost implausible story of how our world went from a barren rock with a sky of endless black, to the planet we know today, cloaked in the thin blue line of our life-sustaining atmosphere. When Earth first formed from clouds of dust and gas 4.6 billion years ago, it was - like so many other lifeless worlds in the universe - devoid of an atmosphere, an inhospitable rock floating in the black void of space. But as the young planet was pummelled by asteroids a period of extraordinary upheaval began. Over a two-billion-year period, the planet faced violent eruptions and a toxic orange haze, vast oceans of water in the sky and seas turning rusty red. Eventually, with the emergence of life and photosynthesis recalibrating the gases in our atmosphere, the stage was set for Earth to become the vibrant azure-skied planet we call home today.

Taking a ferry across the Strait of Gibraltar, Simon's first stop is Ceuta, a Spanish exclave surrounded by Morocco. This is one of the few land borders between Africa and the European Union. Simon joins the Spanish border police who check engines and even dashboards for stowaways trying to reach Europe. Migrant and refugees attempting to cross Ceuta's fortress border have quadrupled in the last year. Undaunted by Morocco's failure to issue a filming permit, Simon crosses the border as a tourist, tracking down a group of young migrants hiding out in a forest close to Ceuta. They have travelled thousands of miles, crossing the Sahara to get this far, and now they are just a 20-foot, razor wire fence away from their European dream. Crossing the Med to Spain, one the busiest shipping lanes in the world, Simon discovers huge numbers of dolphins and even giant whales surviving by dodging the ferries, container ships and oil tankers. Travelling along the arid southern Spanish coast, Simon takes to air to witness the sea of plastic that form over a hundred square miles of greenhouses. It is where much of our supermarket fruit and veg are grown, but as Simon discovers it is a massive industry built on the back of a low paid, migrant workforce. Following in the footsteps of four million Brits who make the journey every year, Simon travels to the Costa Blanca and its most famous resort, Benidorm. Derided by many, Simon is surprised to learn that high-rise Benidorm is now being hailed by experts as a model of sustainable tourism. The Mediterranean region attracts a third of world tourism and visitor numbers are predicted to rise to half a billion a year by the end of the next decade. Simon travels to a western corner of Corsica, a nature reserve that must be one of the most heavily protected bits of sea on earth, and one of the few places where tourists are actively discouraged from visiting. Lying on the beach, hiking in the mountains and watersport activities are all banned. The park's manager shows Simon the results, taking him for a dive in the fishiest place in the Med. In a sea where over ninety percent of fish stocks are over exploited, it is a beacon of hope in what is otherwise an uncertain future for the Mediterranean.

Eight days, three hours, 18 minutes, 35 seconds. That is the total duration of the most important and celebrated space mission ever flown - Apollo 11 - when humans first set foot on the moon. It was a journey that changed the way we think about our place in the universe. But we only saw a fraction of what happened - a handful of iconic stills and a few precious hours of movie footage. Now it is time to discover the full story. Previously classified cockpit audio, recorded by the astronauts themselves, gives a unique insight into their fears and excitement as they undertake the mission. And dramatic reconstruction brings those recordings to life, recreating the crucial scenes that were never filmed - the exhilarating launch, the first sight of the moon, the dramatic touchdown and nail-biting journey home. Original archive footage from the Apollo programme is combined with newly shot film and cinematic CGI to create the ultimate documentary of the ultimate human adventure.

For every pound we spend on food shopping, 77p goes to the supermarkets, giving them a huge influence over what we eat. But can we trust the supermarkets to tell us the truth about what we are buying and how it was produced? Or do their profits come first? In an experiment to discover the hidden truths about our everyday foods, Horizon has built the first ever truly 'honest supermarket'. Drawing on the latest scientific research and leading experts from across the UK, the team have built a supermarket where the products are labelled with the real story of how they are produced and their effect on us and the environment. We invite the British public to come in and discover the truth about their favourite foods. And in our on-site lab, new scientific discoveries reveal the food facts the supermarkets aren't telling you. Presented by Dr Hannah Fry and dietician Priya Tew, The Honest Supermarket takes a cold hard look at what's really going on with the food we eat. From new research that reveals you're likely to be ingesting plastic particles along with your bottled water to the lab tests that uncover the disturbing truth about just how old your 'fresh' supermarket fish really is… You'll never look at the food on your supermarket shelves in the same way again.
