The final episode begins with a description of the extreme cold conditions that characterized the beginning of the Holocene period, and how species like the bison and the wolf adapted to survive in these hostile environments. We will witness the majesty of the woolly mammoth and the fierce cave lion, with a vivid reconstruction of their struggles for survival. We'll see the impact of climate change during this period, from the expansion of the deserts to the transformation of the tropical rainforests of Africa into grasslands, deeply affecting primates and other animals. It highlights how these changes forced primates to adapt to life on the ground, facing new challenges and predators.
A crucial turn occurred with the emergence of humans as dominant predators and their influence on the extinction of large mammals. The documentary describes humanity's transition from hunter-gatherers to farmers, a change that radically altered the landscape and biodiversity of the planet. Finally, it poses a reflection on the current challenges of climate change and the sixth mass extinction, inviting viewers to consider humanity's crucial role in shaping the future of the Earth.

In the boreal forests of Europe, a young brown bear clashes with wolves and tries to find a mate beneath the stars. On the edge of the Arctic Circle, lies an enchanted wilderness. In Europe's boreal forest, It's so far north that in winter, nights can last 20 hours. This woodland is home to a population of secretive bears that lives most of their lives in the dark. But now, using low-light cameras we can see their nighttime world as if it were day.

Enjoy this wonderful documentary from Disney Nature about a family of brown bears living in the coastal mountain ranges of Alaska." A brown bear mother named Sky gives birth to two cubs named Amber and Scout in her den on a mountain slope. When April comes the bears will be ready to leave the den. As the bears leave the oncoming summer brings with it a threat of avalanches. Fortunately the bears are able to avoid disaster. Upon reaching the lush valley below, the cubs meet the other bears, some of which pose a threat to the cubs; among these bears are Magnus, a big healthy male, and Chinook, an older male. The family works together to survive the spring, with Sky keeping the cubs safe from Tikaani, a pesky grey wolf...

Mercedes' W13 Is put to the test at pre-season tests at Bahrain with Lewis Hamilton and new teammate George Russell behind the wheel. However, the car exhibits an incredibly unpleasant drive with an excessive amount of porpoising. The team has noticed the issue and plans to work on it before further tests commence. However, for Mercedes, the issue seems to remain unfixed. Indeed, the issues are present coming to the races at Imola, Spain, and Monaco, before arriving at the Baku City Circuit for Azerbaijan. Lewis' back starts to exhibit pain as he goes down the straights of Baku as Max Verstappen takes home the victory with Lewis taking fourth. After the race, the team principals convene for a meeting, where Toto Wolff of Mercedes expresses his dismay and concern about the safety of the drivers.
The Silverstone round, which also coincided with Zhou Guanyu's big crash coming into Abbey, finishes with Lewis Hamilton taking third place and Carlos Sainz Jr. taking his first career victory in Formula One. Lewis, having questioned the possibilities of retirement following the 2021 season, announces he is here to stay with Mercedes.

(Click CC for subtitles) Rumors fly about whether an up-and-coming driver will join Hamilton on team Mercedes, potentially leaving Valtteri Bottas without a seat. Seemingly permanently stuck in the crisis of a one-year contract running out, this time Bottas has Mercedes golden boy George Russell breathing down his neck. The young Brit desperately wants Bottas’ seat, and things come to a head when the two collide at Imola. Scandalous.
Bottas can’t resist the inevitable though, and after Russell puts the F1 on the front row at Spa, whilst the Finn can only manage eighth, it looks to be all over. Thus follows a scene of Russell being told he has the Mercedes seat by Wolff in a scene which looks so staged it would make even cringe.

This episodes the nature of the cosmos on the micro and atomic scales, using the Ship of the Imagination to explore these realms. Tyson describes some of the micro-organism that live within a dew drop, demonstrating parameciums and tardigrades. He proceeds to discuss how plants use photosynthesis via their chloroplasts to convert sunlight into chemical reactions that convert carbon dioxide and water into oxygen and energy-rich sugars. Tyson then discusses the nature of molecules and atoms and how they relate to the evolution of species. He uses the example set forth by Charles Darwin postulating the existence of the long-tongued Morgan's sphinx moth based on the nature of the comet orchid with pollen far within the flower. He further demonstrates that scents from flowers are used to trigger olfactory centers in the brain, stimulating the mind to threats as to aid in the survival of the species. Tyson narrates how Greek philosophers Thales and Democritus postulated that all matter was made up of combinations of atoms in a large number of configurations, and describes how carbon forms the basic building block for life on earth due to its unique chemical nature. Tyson explains on the basic atomic structure of protons, neutrons, and electrons, and the nature of nuclear fusion that occurs in most stars. He then discusses the existence of neutrinos that are created by these nuclear processes in stars, and that detecting such sub-atomic particles which normally pass through matter require subterranean facilities like the Super-Kamiokande that were used to detect neutrinos from the supernova SN 1987A in the Large Magellanic Cloud before light from the explosion were observed due to their ability to pass through matter of the dying sun. Tyson compares how neutrinos were postulated by Wolfgang Pauli to account for the conservation of energy from nuclear reactions in the same manner as Darwin's postulate on the long-tongued moth. Tyson concludes by noting that there are neutrinos from the Big Bang still existing in the universe but due to the nature of light, there is a "wall of infinity" that cannot be observed beyond.
