Ben Fogle and Victoria Pendleton are guided by professional mountaineer Kenton Cool, a veteran of twelve Everest summits. As they head up the mountain, into the notorious "death zone", physical exhaustion, extreme conditions and misfortune will test the pair to their limits, 65 years after Edmund Hillary and Tenzing Norgay became the first climbers known to have reached the summit. Since that day in 1953, more than 4000 people have successfully climbed Everest but nearly 300 climbers have died on her icy slopes. As Ben and Victoria begin their expedition and face their fears, they know Everest will be life-changing.

One man has seen more of the natural world than any other. This unique feature documentary is his witness statement. Having spent decades traveling the globe and producing some of the most memorable documentaries of all time, few people know the natural world quite like David Attenborough. That’s why he’s so concerned about the issue of climate change, which will threaten humanity’s very survival unless urgent action is taken to halt the damage it has already caused. Attenborough’s latest offering, A Life On Our Planet, is a reflective piece, looking back on his 94 years on Earth and sending a desperate appeal for help in securing its future.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.
