An alarming decline in insect populations could devastate all life on earth. What's causing it, and can anything be done to stop it?
Insects are disappearing across the world. If we lost our pollinators, we would lose 80 to 90% of the plants on the planet. That is not an option. It's the ecosystems on this planet that keep humans alive. Scientists warn us that the insect apocalypse is entirely possible.

35 years after the Chernobyl disaster, Ben Fogle travels to the most radioactive place on Earth. He spends a week living alone inside the Chernobyl Exclusion Zone, gaining privileged access to the doomed Control Room 4 where the disaster first began to unfold.
'The planet faces unprecedented challenges - many of them, like Chernobyl, of our own making. What I've discovered in Chernobyl is that nature's reclaiming it. This is the greatest, accidental rewilding project of the globe. For me, the really exciting part of the Chernobyl story is the accidental hope that came from it. '

Leading authority on the Middle Ages, Professor Robert Bartlett, presents a series which examines the way we thought during medieval times. In the second episode, Bartlett unearths remarkable evidence of the complex passions of Medieval men and women. The Church preached hatred of the flesh, promoted the cult of virginity and condemned woman as the sinful heir to Eve. Yet this was the era that gave birth to the idea of romantic love.

The International Space Station is the ultimate extreme home. Costing $150 billion, it is the most expensive structure humans have ever built, in the most inhospitable environment known to man, with no air food or water. Assembled at 250 miles above the earth, it's an epic engineering challenge. We're going to take it apart and uncover what's going on inside the ISS.
Its superstructure secrets will help our species reach other planets and beyond. Using photo-real computer graphics, we take it apart to uncover the extraordinary innovations that enable it to support life in the deadly vacuum of space.

The most innovative area of human motion lies not on Earth, but with the exploration of space. Space is the most hostile environment we know. Navigating it involves crossing unprecedented distances. It's the greatest engineering challenge humanity has ever undertaken.
Meet the pioneers who've dreamed of reaching other worlds, pushing the boundaries of space exploration, and the private space entrepreneurs jostling to offer the tantalizing prospect of cheap, frequent travel beyond the atmosphere into Earth orbit.

An exploration of active volcanoes in Indonesia, Iceland, North Korea and Ethiopia, Herzog follows volcanologist and co-director Clive Oppenheimer, who hopes to minimize the volcanoes’ destructive impact. What is the Herzog’s quest? To gain an image of our origins and nature as a species. He finds that the volcano—mysterious, violent, and rapturously beautiful—instructs us that, "there is no single one that is not connected to a belief system".
