Every year in Tanzania, the dry season hits the Ruaha reserve hard. To survive, animal populations come down from the high plateaus to reach the Ruaha river, where a troupe of lionesses waits patiently, poised for combat

This investigation by Marie-Monique Robin makes the link between the proliferation of new viruses and the destruction of biodiversity and probes the scientists gathered around the issue of global health. To counter the multiplication of health crises, these specialists advocate the preservation of biodiversity as an antidote.

The "gravity" nightmare is becoming a reality: tons of rocket and satellite parts have been scattered into space over the past 60 years. The fragments collide with other objects, producing more and more scrap - a proliferation that has long since gotten out of control and poses an acute danger to rocket launches and space stations.

For the animal and plant world that lives there, the Kalahari is a region as grandiose as it is unforgiving. For a long time it was thought that only the law of the strongest could survive here. But a completely different strategy is needed: cooperation.

In the Southern Andes, a living being survives since 200 million years: the "Araucaria Araucana" with its incredible history, little known and forever linked to an Amerindian people of Chile: Pehuenches. This isolated community survived during centuries thanks to the Araucarias. A perfect harmony between man and nature, forever upset by the invasion of the Spanish colonists, the conflicts of territories and the increase of logging. Protected today, this sacred forests are the refuge of a unique and wild nature; but fires threaten this balance. What remain of these people and the link with this tree? What can they teach us about our environmental problems?

French author Sylvain Tesson pays tribute to the heroes of the Russian Revolution as he crosses the Pamir mountain range in Tajikistan, which boasts a multitude of peaks at more than 7,000m. They will have the occasion to look back on some of the major figures and events of the Revolution. Lenin Peak, Revolution Peak, Karl Marx Peak, and also the October Glacier and the Soviet Officer range – all names which evoke the Revolution in these remarkable yet little-known locations. He is accompanied by two friends, author and lover of all things Russian, Cédric Gras, and the former Soviet mountaineering instructor, Nicolay Taran. Along the way, the author and his traveling companions observe the traces left by the former USSR on daily life here, and they listen to the memories of the populations who live in the Pamirs, whether Kyrgyz nomads on the high plateaus or Ismailis in the valleys. For Sylvain Tesson, the journey will serve as a source of inspiration for his future writing.

Nature is an inexhaustible source of knowledge. After 3 billion years of evolution, it has created amazing mechanisms, even at a microscopic level, that allow plants and animals around us to protect themselves, to grow, to move or to face the attacks of the elements. This "nanoworld" questions our imagination with its beauty and intelligence. Scientists have finally managed to unravel its mysteries, thanks to photonics. Let’s take an unprecedented journey into this other dimension, in which nature-inspired solutions are found to meet the meet the ecological and climatic challenges that threaten us.

In the heart of southern France there is a fog-prone area where, according to legend, a bloodthirsty creature wreaked havoc 250 years ago. A rumor is spreading again in this legendary place, as eyewitnesses report an animal with large paws and a long tail that crosses roads in a single leap - powerful enough to tear down a horse and leave it mutilated in the pasture. Is the Beast of Gévaudan back? The animal photographer Bruno Loisel has a supposedly more rational explanation. The animal that fits the descriptions could be a cougar, but this species of big cat is only native to America. In order to learn the proper techniques for tracking down the puma, he travels to Canada, where he accompanies a team of researchers dedicated to studying the shy, almost invisible predator. Will Bruno be able to use his findings to solve the mystery of the new beast of Gévaudan?

It can’t be denied that our planet is burning and the NGOs seem overwhelmed by the number of catastrophic situations to be managed... As soon as one fire goes out, another one is lit on the other side of the world. While Greenpeace had obtained a moratorium on deforestation in the Amazon, Bolsonaro’s coming to power was enough to undo the long and patient work of the NGO. Now activists of a new kind are planning to file a complaint against the Brazilian dictator, in the name of nature. It is advocates and lawyers taking over; white-collar rangers whose clients are rivers, forests and wildlife. They militate for nature to be recognised as a legal entity, in order to file a complaint on its behalf and represent them in court. Indeed, they look for all the loopholes in the laws and attack the enemies of nature on their own ground.

Rather than learning France's history through its people, we explore its natural history. A two billion-year journey back in time to look at the country's geological heritage: a mountain chain becomes Brittany, lagoons where Paris now stands, ice from the Aiguille du Midi maps the routes of rivers flowing seawards.

For more than a decade, wildfires of unprecedented force have been devouring our lives, homes and forests at a steady pace. Each year, 350 million hectares of forest go up in smoke, the equivalent of six times the size of France. In the US, the fire season now lasts up to two months longer than a generation ago, and the surface burnt annually has multiplied by three. This film sets out on a gripping journey of investigation from Europe to the US, Canada, Brazil and Indonesia to follow the work of a global team of dedicated firefighters, scientists and fire experts as they investigate why our forests are going up in flames, and act on an unexpected discovery: if we want to save our forests, homes, health and our climate, we need to radically change our attitude towards fire and the way we fight wildfires.

1947. The rush to the poles marked the beginning of an incredible human adventure to discover the last-remaining unknown lands. In France, Paul-E?mile Victor persuaded the government to finance expeditions to explore the Arctic and Antarctic. For the pioneers the conditions were Dantean, all in the name of science.

In October 2010, two of France's top mountaineers, Christophe Dumarest and Yann Borgnet, fulfilled a mountaineer's dream: a six-day alpine-style ascent of Walter Bonatti's great routes through the Mont Blanc massif. Dumarest and Borgnet first climbed the north face of the Grandes Jorasses; they then climbed the Grand Capucin and the Pilier Rouge du Brouillard, completing their feat with the ascent of Mont Blanc. Their paragliding descent in Chamonix completes their feat with a touch of fun. The climbers and the director made the ethical choice not to use helicopters to shoot the film.

Writer Cédric Gras follows in the footsteps of Stalinist mountaineers in Kyrgyzstan. Pioneers of Central Asian exploration, they were first on the highest peaks of the Celestial Mountains. The film traces one of their expeditions to the Khan Tengri, which has become an amazing glacial trek.

Kenya, 2050. The reserve has dwindled to half its size, under pressure from farmers who have enlarged their territory at the expense of the animals. Among the latter, the last giraffe just died. To be able to admire this fabulous beast again, you’d have to go back to 2016, when it became clear that the biggest living land animal was threatened with extinction due to poaching and loss of habitat. Thanks to some spectacular images of this enchanted place with its abundant biodiversity, this film offers a new type of documentary experience, to understand how this symbol of the African continent could end up disappearing from the planet. By imagining its future, it reveals to us the reality of life in the wild and the daily life of this animal, few of which reach adulthood. We follow in the footsteps of Twiga's family, one of the last baby giraffes, who attends helplessly at the death of his mother. A heartfelt tribute to this mammal whose unique anatomy continues to fascinate.
