"[ Vocalizing Continues ]" "Today, life- our life- is just a link in a chain of innumerable living beings... that have succeeded one another on Earth over nearly four billion years." "And even today, new volcanoes continue to sculpt our landscapes." "They offer a glimpse of what our Earth was like at its birth- molten rock surging from the depths, solidifying, cracking, blistering or spreading in a thin crust, before falling dormant for a time." "These wreaths of smoke curling from the bowels of the Earth... bear witness to the Earth's original atmosphere." "An atmosphere devoid of oxygen." "A dense atmosphere, thick with water vapor, full of carbon dioxide." "A furnace." "But the Earth had an exceptional future, offered to it by water" "At the right distance from the sun- not too far, not too near- the Earth was able to conserve water in liquid form." "Water vapor condensed and fell in torrential downpours on Earth, and rivers appeared." "The rivers shaped the surface of the Earth, cutting their channels, furrowing out valleys." "They ran toward the lowest places on the globe to form the oceans." "They tore minerals from the rocks, and gradually the freshwater of the oceans... became heavy with salt." "Water is a vital liquid." "It irrigated these sterile expanses." "The paths it traced are like the veins of a body, the branches of a tree, the vessels of the sap that it brought to the Earth." "[ Chorus Vocalizing ]" "Nearly four billion years later, somewhere on Earth can still be found these works of art, left by the volcanoes' ash, mixed with water from Iceland's glaciers."

"A miracle of time, primitive life-forms still exist in the globe's hot springs." "They give them their colors." "They're called archaeobacteria." "They all feed off the Earth's heat- all except the cyanobacteria, or blue-green algae." "They alone have the capacity to turn to the sun to capture its energy" "They are a vital ancestor of all yesterday's and today's plant species." "These tiny bacteria... and their billions of descendants... changed the destiny of our planet." "They transformed its atmosphere." "What happened to the carbon that poisoned the atmosphere?" "It's still here, imprisoned in the Earth's crust." "We can read this chapter of the Earth's history... nowhere better than on the walls of Colorado's Grand Canyon." "They reveal nearly two billion years of the Earth's history." "Once upon a time, the Grand Canyon was a sea inhabited by microorganisms." "They grew their shells by tapping into carbon from the atmosphere... dissolved in the ocean." "When they died, the shells sank... and accumulated on the seabed." "These strata are the product of those billions and billions of shells." "Thanks to them, the carbon drained from the atmosphere, and other life-forms could develop." "It is life that altered the atmosphere." "Plant life fed off the sun's energy, which enabled it to break apart the water molecule... and take the oxygen." "And oxygen filled the air." "The Earth's water cycle is a process of constant renewal." "Waterfalls, water vapor, clouds, rain, springs, rivers, seas, oceans, glaciers." "The cycle is never broken." "There's always the same quantity of water on Earth." "All the successive species on Earth have drunk the same water." "The astonishing matter that is water." "One of the most unstable of all." "It takes a liquid form as running water, gaseous as vapor... or solid as ice." "In Siberia, the frozen surfaces of the lakes in winter... contain the traces of the forces that water deploys when it freezes." "Lighter than water the ice floats, rather than sinking to the bottom." "It forms a protective mantle against the cold, under which life can go on." "The engine of life is linkage." "Everything is linked." "Nothing is self-sufficient." "Water and air are inseparable, united in life and for our life on Earth." "Thus, clouds form over the oceans and bring rain to the landmasses, whose rivers carry water back to the oceans." "Sharing is everything." "The green expanse peeking through the clouds is the source of oxygen in the air" "Seventy percent of this gas, without which our lungs cannot function, comes from the algae that tint the surface of the oceans." "Our Earth relies on a balance... in which every being has a role to play... and exists only through the existence of another being." "A subtle, fragile harmony that is easily shattered." "Thus, corals are born from the marriage of algae and shells." "The Great Barrier Reef, off the coast of Australia, stretches over 350,000square kilometers... and is home to 1,500 species of fish," "4,000 species of mollusks... and 400 species of coral." "The equilibrium of every ocean depends on these corals." "The Earth counts time in billions of years." "It took more than four billion years for it to make trees." "In the chain of species, trees are a pinnacle, a perfect living sculpture." "Trees defy gravity." "They are the only natural element in perpetual movement toward the sky." "They grow unhurriedly toward the sun that nourishes their foliage." "They have inherited from those minuscule cyanobacteria... the power to capture light's energy." "They store it and feed off it, turning it into wood and leaves, which then decompose into a mixture of water, mineral, vegetable and living matter." "And so, gradually, the soils that are indispensable to life are formed." "Soils are the factory of biodiversity."

"Monoculture is easy, productive and rapid." "For local people, it provides employment." "It is an agricultural industry." "Another example of massive deforestation is the eucalyptus." "Eucalyptus is used to make paper pulp." "Plantations are growing, as demand for paper has increased fivefold in 50 years." "Monocultures of trees are gaining ground all over the world." "But a monoculture is not a forest." "By definition, there is little diversity" "One forest does not replace another forest." "At the foot of these eucalyptus trees, nothing grows, because their leaves form a bed... that is toxic for most other plants." "They grow quickly but exhaust water reserves."

"Here in Siberia and elsewhere across the globe, it is so cold that the ground is constantly frozen." "It's known as permafrost." "Undents surface lies a climatic time bomb: methane, a greenhouse gas 20 times more powerful than carbon dioxide." "If the permafrost melts, the methane released... would cause the greenhouse effect to race out of control, with consequences no one can predict." "We would literally be in unknown territory." "Humanity has no more than 10 years to reverse the trend... and avoid crossing into this territory- life on Earth as we have never known it."
