Chapters

• 00:00 - 02:00: Introduction and Earth's Early Atmosphere In the early days of Earth, slightly over four billion years ago, the planet was a fiery sphere heavily bombarded by elements in the solar system. Its primordial atmosphere was composed of dense gases, including methane.
• 02:00 - 05:00: Origins of Life and Humanity's Connection to the Ocean In the early days of Earth, the atmosphere was toxic and unbreathable, filled with ammonia. However, over millions of years, a series of events such as collisions, volcanic eruptions, and combustion processes released other gases trapped inside the planet. This led to the release of gases like nitrogen, water vapor, and carbon dioxide, primarily from active volcanoes, which began to shape the Earth's climate, setting the stage for the possibility of life.
• 05:00 - 08:00: Exploration of the Biodiversity Triangle and the Bajau People In this chapter, the importance of water vapor in the atmosphere is discussed, particularly focusing on how it facilitates the spread of oxygen. The exploration of biodiversity in the context of this natural process is also a key point in understanding the environmental dynamics that support diverse biological communities, with a special interest in the Bajau people.
• 08:00 - 13:00: Weather Monitoring in the Arctic The chapter titled "Weather Monitoring in the Arctic" explores the interconnectedness of mankind and the ocean, emphasizing our birthplace on this planet and its fragility. It highlights the vast blue planet, predominantly covered by water, and the billions of years and unique conditions required for human existence. The narrative warns that this delicate balance, which took eons to develop, is threatened by global warming, potentially leading to the disappearance of mankind. The ocean and humans are intricately linked, and their harmony is crucial to our survival.
• 13:00 - 21:00: Humboldt Current and Fishing in Peru The chapter titled 'Humboldt Current and Fishing in Peru' explores the significance of oceans in regulating Earth's climate. It highlights the journey of a team of scientists aboard Tara, who investigate the climatic origins off the coast of Peru, focusing on the giant squid fisheries. The narrative underscores how the ocean 'breathes' and the essential function it serves akin to a lung for the planet. The chapter sets a course for understanding this phenomenon, initiating the journey from the Arctic Ocean.
• 21:00 - 30:00: Tara Expedition and Plankton's Role in Climate Regulation The chapter discusses the Tara Expedition, focusing on its exploration near the island of Sulawesi and the Mikasa Strait, areas known for rich biodiversity. It highlights the lifestyle of the ocean's last nomads, the Bajau, who live in harmony with the sea, and introduces the concept of plankton's role in climate regulation.
• 30:00 - 42:00: Nomadic Life of the Bajau and Ocean's Breath The chapter 'Nomadic Life of the Bajau and Ocean's Breath' explores the connection between the Bajau community and the ocean. According to a legend, their ancestors were forced to become seafaring nomads due to a great flood that submerged their homeland. After seven days and nights adrift, they found a new paradise-like home where they have lived in harmony. Their lives are deeply attuned to the ocean and climate, as they constantly monitor changes in the sky, suggesting a deep cultural integration with their maritime environment.
• 42:00 - 56:00: Birds as Climate Indicators Expeditions in Greenland The chapter titled 'Birds as Climate Indicators Expeditions in Greenland' opens with a description of a routine practice by the Sauron clan. Each day, the clan leader and his son venture out to sea to fish, adhering to traditions that have been in place for generations. This activity is depicted as being deeply ingrained in their lifestyle and connected to the clan's cultural heritage. The narrative suggests a spirtual belief held by the clan that humanity was crafted by ancestral spirits, resulting in the formation of four distinct populations.
• 56:00 - 73:00: Threats to the Oceanic Ecosystem The chapter discusses the historical decision of the BA Jos people who chose to master the ocean over learning to write. This cultural choice is highlighted as a defining characteristic of their existence, as they have lived off the sea for generations. The focus remains on their fishing traditions and the deep-rooted connection with the ocean.

• 40:30 - 41:00 now we never sleep on the ground everything on the ground bites us and itches especially when the night falls we're very scared at the forest there are things there that can strangle you if we're not back on the boat we're not at ease the forest demon can come out at any moment and suffocate us if we stay
• 41:00 - 41:30 there [Music] see spirits are good they warn us of any danger they look like lizards they swim up to us directly to the boats to warn us you're not allowed here it's better over there and if we treat each other badly there's a risk that the sea spirits will abandon us to keep our relationship good
• 41:30 - 42:00 we have to make offerings to the ocean and if we behave well nothing can happen to us [Music] luckily for the bad girl out by letting the watchful lizard steer them they're being guided by the sea and with it the currents the Sun and the plankton that are the origins of life on the other
• 42:00 - 42:30 side of the world spring has arrived early in a few weeks the snow will give way to sand the ice field is about to disappear the sea will gradually free itself from the ice and that's where Slava is heading with a strange fishing rod in his hand he's about to take the temperature of the Arctic Ocean
• 42:30 - 43:00 that or initial universe' so the temperature is minus 1.8 degrees on the top layer of the water the ice has lumps of nine to ten points and that's it job done before there was the ice field
• 43:00 - 43:30 last year it had practically disappeared whereas three four five years ago it stretched out two to three kilometers all throughout the Earth's history there have been similar changes warming's followed by Cooling's laura the sea it's my whole life I can't live without it
• 43:30 - 44:00 even if I retire I wouldn't be able to stay for long away from the sea you need to spend many years here to feel things it's hard to put into words and then without another word Slava turns and heads back on the Terra expedition boat Gabi Gorski continues his mission he's
• 44:00 - 44:30 getting ready to inspect the plankton who are at the origin of the climate more closely as small as they are if the plankton suffer our stress related to the rise in temperature that consequences could be fatal and it seems that a last-minute guest could already be threatening this fragile balance we have two specimens that are typical in these waters the co pods the little grains of rice and the amphipods with
• 44:30 - 45:00 the big eyes unfortunately there's also plastic floating on the surface bits of plastic [Music] Gusti a shock given that there has been life on this planet for we think nearly four billion years plastic has only existed for sixty years yet we've managed to pollute all of the waters from the north to the South Pole all the oceans nearly all of the rivers everywhere - diesel cell yeah I
• 45:00 - 45:30 sometimes tell students that is not worth throwing away your plastic bags just add some seasoning and eat it directly in any case it will find its way back onto your plates the facts young law is already on the image you can see the division and that will go back into the food chain up to the fish we know that but that's where I'm optimistic because I think everyone can
• 45:30 - 46:00 understand that including the politicians Danka and so make the effort to replace unnecessary plastic with biodegradable alternatives we know that plastic is dangerous for the food chain and for our health but it is dangerous for the climate as well by blocking the light or polluting the nutrients plastic disrupts the development of plankton jeopardizing the links that unite the sky mankind and
• 46:00 - 46:30 the sea Victor Silva doesn't want to accept this sad analysis only just returned from his successful giant squid fishing he's already left again this time with his wife and daughter he takes them to the Isla FACA where they can find at least 54 species of fish 32 species of mollusks mammals starfish and crustaceans and plenty of plankton of course and then away from prying eyes they spot an unusual colony which they
• 46:30 - 47:00 have to dock and climb up to observe go on darling a few sea lions are basking in the sunshine they're the main competition for the fishermen as they also eat the giant squid a few years ago local fishermen killed thousands of them with their oars but Victor disapproves and he has his reasons we wanted to come here
• 47:00 - 47:30 to show Bianca the diversity of marine wildlife he is special two currents merge and so there are sea lions penguins many different birds it's the first time that she's seen all these animals few fishermen think like that most only consider their own interests it's opportunism
• 47:30 - 48:00 I've been fishing for over 20 years and every day I see that the water temperature rises a little bit I'd like my voice to be heard because we have to know the damage that man is doing to the sea and marine life species are disappearing for example there are no more sardines here and in other parts of the world like off the coast of Spain there aren't as many fish as before we
• 48:00 - 48:30 need to wake up to this for our children our grandchildren that's my message we have to wake up the ocean is the climate's main regulator every living being depends on this fragile balance tomorrow's world depends on us waking it up
