The last chapter explains how the 2010s became another lost decade in the fight against climate change – as the move to natural gas delayed a transition to more renewable sources of energy.
Engineer Tony Ingraffea, in the 1980s, helped develop a new technique for extracting gas and oil from shale rock, which ultimately became known as 'Fracking'. It was to unleash vast new reserves of fossil fuels and was promoted as a cleaner energy source. But Ingraffea explains how he later came to regret his work when he realized that gas could be even worse for climate change than coal and oil.
Dar-Lon Chang, a former ExxonMobil engineer, speaks for the first time on camera alleging that as the company increased its natural gas operations, it was not sufficiently monitoring methane leaks that were contributing to climate change. Now, after a year of unprecedented wildfires, drought and other climate-related disasters, multiple lawsuits are being brought in US courts in efforts to hold Big Oil legally accountable for the climate crisis.

Americans consider themselves a 'nation of immigrants,' but as the catastrophe of the Holocaust unfolded in Europe, the United States proved unwilling to open its doors to more than a fraction of the hundreds of thousands of desperate people seeking refuge.
Through riveting firsthand testimony of witnesses and survivors who as children endured persecution, violence and flight as their families tried to escape Hitler, this series delves deeply into the tragic human consequences of public indifference, bureaucratic red tape and restrictive quota laws in America. Did the nation fail to live up to its ideals? This is a history to be reckoned with.
In the first episode, a xenophobic backlash prompts Congress to restrict immigration. Hitler and the Nazis persecute German Jews, forcing many to seek refuge. Franklin D. Roosevelt is concerned by the growing crisis but is unable to coordinate a response.

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 mind boggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

This series is a searing indictment of Big Pharma and the political operatives and government regulations that enable over-production, reckless distribution and abuse of synthetic opiates. Exploring the origins, extent and fallout of one of the most devastating public health tragedies of our time, with half a million deaths from overdoses this century alone, the film reveals that America's opioid epidemic is not a public health crisis that came out of nowhere.
In the first part, a look at how Purdue Pharma worked with the FDA to get OxyContin approved for wider use, promoting the highly profitable pain medication's safety without sufficient evidence, and creating a campaign to redefine pain and how it's treated.

David Attenborough and the world-renowned scientist Johan Rockström examine Earth's biodiversity collapse. The film explains how humanity has pushed our planet beyond the boundaries that have kept it stable since the dawn of life, but also that this crisis can still be averted, thinking and acting with one unified purpose to ensure that Earth forever remains healthy and resilient.

Just outside Paris, inside a hi-tech vault, and encased in three vacuum-sealed bell jars, rests a small metallic cylinder about the diameter of a golf ball. It may not look like much, but it is one of the most important objects on the planet. It affects nearly every aspect of our lives including the food we eat, the cars we drive, even the medicines we take. It is the Kilogramme, the base unit of mass in the International System of Units. Yet over time, its mass has mysteriously eroded by the weight of an eyelash. A change that, unbeknownst to most, unleashed a crisis with potentially dire consequences.
The film follows the ensuing high-stakes, two-year race to redefine the weight of the world, and tells the story of one of the most important objects on the planet.
