A rain forest is the richest habitat on Earth. Exactly how many species rain forests contain is unknown, but it runs into millions. And new ones are discovered every week. There are some, like the clouded leopard, we still know virtually nothing about. Although they cover just seven percent of the world's land area, jungles play a vital role in the health of the planet . Jungles and rainforests are home to an incredible variety of species like preening birds, intelligent orangutans and remarkably ambitious ants.
The search for climate change solutions requires passion, resources and a sense of urgency -- three qualities Bill Gates clearly possesses. Bill has founded a start-up called TerraPower. After extensive computer modelling, the idea showed promise. Its new reactor greatly reduced the chance of human error. Fuelled by depleted uranium, the travelling wave reactor functions like a slow-burning candle and requires refuelling only once every decade. Bill and his team believed they had finally developed the ideal energy source, a reactor that was clean, efficient, and most importantly, safe.

Pavarotti is a riveting film that lifts the curtain on the icon who brought opera to the people. Ron Howard puts audiences front row center for an exploration of the voice, the man, the legend. Luciano Pavarotti gave his life to the music and a voice to the world. This cinematic event features history-making performances and intimate interviews, including never-before-seen footage and cutting-edge Dolby Atmos technology. Born in 1935 in Modena in a worker-class family, Luciano Pavarotti felt since his childhood the passion by opera due to his father, an amateur tenor. Blessed with a powerful voice and student of the most important Italy's opera teachers of those times, soon the name of Pavarotti turned in a reference of the genre, giving some of the most remembered live performances in the most important theaters across the world, meeting with politicians and world leaders as well as rock and pop singers to bring concerts for humanitarian causes, over-passing any limit when he was part of The Three Tenors with the too opera singers José Carreras and Plácido Domingo.
A deep sea diver is stranded on the seabed with 5 minutes of oxygen and no hope of rescue. With access to amazing archive this is the story of one man's impossible fight for survival. Chris Lemons were carrying out repairs 100m below the surface of the North Sea, supported by the vessel Bibby Topaz. The vessel's dynamic positioning system failed, causing it to snap the umbilical tether that provided Lemons oxygen, as well as hot water to heat his suit, power for his light, and a radio link to the surface. He was left with only the few minutes of breathable gas contained in the cylinders he wore on his back. For reasons that are unclear, Lemons survived for around 30 minutes while he was located by a remote underwater vehicle and then by Yuasa, who was able to pull him back onboard the diving bell. The documentary uses genuine footage and audio recorded at the time of the accident on the divers' radios and body cameras, supplemented with interviews of several of the individuals involved, as well as some reconstructed footage, to tell the story of the accident.
Everything that lives on land, animal or plant, depends on fresh water. Yet only part of it is within reach: Much of the planet's fresh water, is locked away, almost two-thirds of it lies frozen around the poles. Even away from the poles, much of the land's fresh water freezes each winter. The need for fresh water is as strong as ever. However, the supply is becoming increasingly unpredictable and uncertain for all manner of species. We are not alone in our need for water, but we have the ability to ensure the fresh waters of the world do flow, and we alone can determine how they are shared.
