Stacey Dooley travels the world to uncover the hidden costs of the addiction to fast fashion. She sees for herself how toxic chemicals released by the garment industry pollute waterways that millions of people rely on. She witnesses the former Aral Sea, once one of the largest bodies of fresh water, now reduced almost entirely to dust. These are shocking discoveries likely to make you think twice about whether you really need those new clothes.
When you soar above Yellowstone, it's easy to see why it became the world's first national park in 1872. It's a place of staggering beauty and fragile creatures, of stunning granite peaks that pierce the sky and colorful springs that may hold secrets about the origins of life. This aerial voyage takes you over high elevation lakes, snaking canyons, sputtering hot geysers, and snow-covered landscapes. Explore Yellowstone's history of Native Americans, European explorers, and 10 million years of tectonic upheaval.

On 26 April 1986, reactor number four at the Chernobyl Nuclear Power Plant blew up. Forty-eight hours later the entire area was evacuated. Over the following months there were stories of mass graves and dire warnings of thousands of deaths from radiation exposure.
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.
This episode focuses on the Asia-Pacific side of The Pacific Rim of Fire, which stands as a living testament to the beauty and danger that powerful geologic forces can deliver. The Pacific Rim is home to half of the world's active volcanoes and ninety percent of the world's earthquakes, yet nearly 800 million people continue to live within its violent edge. Our journey begins in New Zealand, a land of volcanoes and earthquakes, where we find a 500-kilometre long slip-strike fault deep under the Pacific Ocean. Geologist Hamish Campbell will take us to the crater of White Island, the country’s most active volcano. Then we'll visit the country's southern island with John Youngson, to find out how New Zealand’s longest fault-line contributes to the gold industry. Finally in Japan, viewers will hike up to Mount Fuji – the iconic peak where science and legend converge, getting up-close and personal with a fault-line witnessing firsthand what it’s like to discover new ways of monitoring, and hopefully one day predicting, seismic activity onboard the world’s most advanced drilling vessels.
