HOME by Yann Arthus-Bertrand (Text Version Part I)
(My transcript version of this
awesome documentary “HOME” goes with a prayer for the filmmakers’
permission. Otherwise I shall be obliged to remove this on a short
notice. HOME, I believe, is the best environmental documentary I have
ever seen in years and this text version serves to share and extend the
movie from the “viewing” to the reading public and for all the world’s
enlightenment. I’ve decided to divide this in three parts so as not to
squeeze your vertical scroll bar too tight. And I would greatly
appreciate it if you would give me a piece of your mind by leaving a
comment. Now open your eyes..)
Listen
to me please. You’re like me, a homo sapiens, a wise human. Life, a
miracle of the universe appeared around four billion years ago and we
humans only 200 thousand years ago. Yet we have succeeded in disrupting
the balance that is so essential to life on Earth. Listen carefully to
this extraordinary story which is yours and decide what you want to do
with it. These are traces of our origins. At the beginning, our planet
was no more than a chaos of fire formed in the wake of its star. The
sun, a cloud of a good knitted dust particles similar to so many similar
clusters in the universe. Yet this was where the miracle of life
occurred.
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 bare 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. 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. There they
are-matter and water, water and matter, soft and hard combined, the
crucial alliance shared by every life-form on our planet. Minerals and
metals are even older than the Earth.
They
are stardust. They provide the Earth’s colors. Red from iron, black
from carbon, blue from copper, yellow from sulfur. Where do we come
from? Where did life first spark into being? 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 bacterias and their billions of descendants change 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 exist 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 350,000 square 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 a 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. They are a world of incessant
activity where microorganisms feed, dig, aerate and transform. They make
the humus, the fertile layer to which all life on land is linked.
What do we know about life on Earth? How
many species are we aware of? A 10th of them? A hundredth perhaps? What
do we know about he bonds that link them? The Earth is a miracle. Life
remains a mystery. Families of animals form united by customs and
rituals that survive today. Some adapt to the nature of their pasture,
and their pasture adapts to them. And both gained. The animal sates its
hunger and the tree can blossom again. In the great adventure of life on
Earth. Every species has a role to play, every species has its place.
None is futile or harmful. They all balance out. And that’s where you,
Homo Sapiens-“wise human”-enter the story. You benefit from a fabulous
four-billion-year-old legacy bequeathed by the Earth. You’re only
200,000 years old, but you have changed the face of the world. Despite
your vulnerability, you have taken possession of every habitat and
conquered swaths of territory like no other species before you. After
180,000 nomadic years, and thanks to a more clement climate, humans
settled down. They no longer depended on hunting for survival. They
chose to live in wet environments that abounded in fish, game and wild
plants. There, where land, water and life combine. Human genius inspired
them to build canoes, an invention that opened up new horizons and
turned humans into navigators.
Even today the majority of mankind lives
on the continents’ coastlines or the banks of rivers and lakes. The
first towns grew up less than 600 years ago. It was a considerable leap
in human history. Why towns? Because they allowed humans to defend
themselves more easily. They became social beings meeting and sharing
knowledge and crafts, blending their similarities and differences. In a
word, they became civilized. But the only energy at their disposal was
provided by nature and the strength of their bodies. It was the story of
humankind for thousands of years. It still is for one person in
four-over one and a half billion human beings, more than the combined
population of all the wealthy nations. Taking from the Earth only the
strictly necessary. For a long time, the relationship between humans and
the planet was evenly balanced. For a long time, the economy seemed
like a natural and equitable alliance. But life expectancy is short, and
hard labor takes its toll. The uncertainties of nature weigh on daily
life. Education is a rare privilege. Children are a family’s only asset,
as long as every extra pair of hands is a necessary contribution to its
subsistence. The Earth feeds people, clothes them and provides for
their daily needs. Everything comes from the Earth. Towns change
humanity’s nature as well as its destiny. The farmer becomes a
craftsman, trader or peddler. What the Earth gives the farmer, the city
dweller buys, sells or barters. Goods changed hands along with ideas.
Humanity’s genius is to have always had a sense of its weakness. Humans
tried to extend the frontiers of their territory, but they knew their
limits. The physical energy and strength with which nature had not
endowed them was found in the animals they domesticated to serve them.
But how can you conquer the world on an empty stomach?
The
invention of agriculture transformed the future of the wild animals
scavenging for food that were humankind. Agriculture turned their
history on end. Agriculture was their first great revolution. Developed
barely 8,000 to 10,000 years ago, it changed their relationship to
nature. It brought an end to the uncertainty of hunting and gathering.
It resulted in the first surpluses and gave birth to cities and
civilizations. For their agriculture humans harnessed the energy of
animal species and plant life, from which they at last extracted the
profits. The memory of thousands of years scrabbling for food faded.
They learned to adapt the grains that are the yeast of life to different
soils and climates. They learned to increase the yield and multiply the
number of varieties. Like every species on Earth, the principal daily
concern of all humans is to feed themselves and their family. When the
soil is less generous and water becomes scarce, humans deploy prodigous
efforts to mark a few arid acres with the imprint of their labor. Human
shaped the land with the patience and devotion that the Earth demands in
an almost sacrificial ritual performed over and over. Agriculture is
still the world’s most widespread occupation. Half of humankind tills
the soil over three-quarters of them by hand. Agriculture is like a
tradition handed down from generation to generation in sweat, graft and
toil because for humanity it is a prerequisite of survival. But after
relying on muscle power for so long, humankind found a way to tap into
the energy buried deep in the Earth. These flames are also from plants. A
pocket of sunlight. Pure energy-the energy of the sun-captured over
millions of years by millions of plants more than a hundred million
years ago. It’s coal. It’s gas. And above all, it’s oil.
And
this pocket of sunlight freed humans from their toil on the land. With
oil began the era of humans who break free of the shackles of time. With
oil, some of us acquired unprecedented comforts. And in 50 years, in a
single lifetime, the Earth has been more radically changed than by all
previous generation of humanity. Faster and faster. In the last 60
years, the Earth’s population has almost tripled, and over two billion
people have moved to the cities. Faster and faster. Shenzhen, in China,
with its hundreds of skyscrapers and millions of inhabitants, was just a
small fishing village barely 40 years ago. Faster and faster. In
Shanghai, 3,000 towers and skyscrapers have been built in 20 years.
Hundreds more are under construction. Today, over half of the world’s
seven billion inhabitants live in cities. New York. The world’s first megalopolis
is the symbol of the exploitation of the energy the Earth supplies to
human genius. The manpower of millions of immigrants, the energy of
coal, the unbridled power of oil. Electricity resulted in the invention
of elevators which in turn permitted the invention of skyscrapers. New
York ranks as the 16th-largest economy in the world. America was the
first to discover, exploit and harness the phenomenal revolutionary
power of black gold. With its help, a country of farmers became a
country of agricultural industrialists. Machines replaced men. A liter
of oil generates as much energy as 100 pairs of hands in 24 hours, but
worldwide only three percent of farmers have use of a tractor.
Nonetheless, their output dominates the planet. In the United States,
only three million farmers are left. They produce enough grain to feed
two billion people.
But most of that grain is not used to feed people. Here, and in all
other industrialized nations, it’s transformed into livestock feed or
bio-fuels. The pocket of sunshine’s energy chased away the specter of
drought that stalked farmland. No spring escapes the demands of
agriculture, which accounts for 70% of humanity’s water consumption. In
nature, everything is linked. The expansion of cultivated land and
single-crop farming encouraged the development of parasites. Pesticides,
another gift of the petrochemical revolution, exterminated them. Bad
harvests and famine became a distant memory. The biggest headache now
was what to do with the surpluses engendered by modern agriculture. But
toxic pesticides seeped into
the air, soil, plants, animals, rivers and oceans. They penetrated the
heart of cells similar to the mother cell that is shared by all forms of
life. Are they harmful to the humans that they released from hunger?
These farmers, in their yellow protective suits, probably have a good
idea.
The
new agriculture abolished the dependence on soils and seasons.
Fertilizers produced unprecedented results on plots of land thus far
ignored. Crops adapted to soils and climates gave way to the most
productive varieties and the easiest to transport. And so in the last
century, three-quarters of the varieties developed by farmers over
thousands of years have been wiped out. As far as the eye can see
fertilizer below, plastic on top. The greenhouses of Almeria in Spain
are Europe’s vegetable garden. A city of uniformly sized vegetables
waits every day for the hundreds of trucks that will take them to the
continent’s supermarkets. The more a country develops, the more meat its
inhabitants consume. How can a growing worldwide demand be satisfied
without recourse to concentration camp-style cattle farms? Faster and
faster. Like
the life cycle of livestock which may never see a meadow manufacturing
meat faster than the animal has become a daily routine. In these vast
food lots, trampled by millions of cattle, not a blade of grass grows. A
fleet of trucks from every corner of the country brings in tons of
grains, soy meal and protein-rich granules that will become tons of
meat. The result is that it takes 100 liters of water to produce one
kilogram of potatoes, 4,000 for one kilo or rice and 13,000 for one kilo
of beef. Not to mention the oil guzzled in the production process and
transport.
Our agriculture has become oil-powered.
It feeds twice as many humans on Earth but has replaced diversity with
standardization. It has offered many of us comforts we could only dream
of, but it makes our way of life totally dependent on oil. This is the
new measure of time. Our world’s clock now beats to the rhythm of these
indefatigable machines tapping into the pocket of
sunlight. Their regularity reassures us. The tiniest hiccup throws us
into disarray. The whole planet is attentive to these metronomes of our
hopes and illusions. The same hopes and illusions that proliferate along
with our needs increasingly insatiable desires and profligacy. We know
that the end of cheap oil is imminent, but we refuse to believe it. For
many of us, the American dream is embodied by a legendary name: Los
Angeles.
In
this city that stretches over 100 kilometers, the number of cars is
almost equal to the number of inhabitants. Here energy puts on a
fantastic show every night. The day seem to be no more than the pale
reflection of nights that turn the city into a starry sky. Faster and
faster. Distances are no longer counted in miles but in minutes. The
automobile shapes new suburbs where every home is a castle, a safe
distance from the asphyxiated city centers, and where neat rows of
houses huddle round dead-end streets. The model of a lucky few countries
has become a universal dream preached by televisions all over the
world. Even here in Beijing is cloned, copied and reproduced in these
formatted houses that have wiped pagodas off the map.
The automobile has become the symbol of comfort and progress. If this
model were followed by every society, the planet wouldn’t have 900
million vehicles, as it does today, but five billion. Faster and faster.
The more the world develops, the greater its thirst for energy.
Everywhere, machines dig, bore and rip from the Earth the pieces of
stars buried in its depths since its creation: minerals.
In
the next 20 years, more ore will be extracted from the Earth than in
the whole of humanity’s history. As a privilege of power, 80% of this
mineral wealth is consumed by 20% of the world’s population. Before the
end of this century excessive mining will have exhausted nearly all the
planet’s reserves. Faster and faster. Shipyards churn out oil tankers,
container ships and gas tankers to cater for the demands of globalized
industrial production. Most consumer goods
travel thousands of kilometers from the country of production to the
country of consumption. Since 1950, the volume of international trade
has increased 20 times over. Ninety percent of trade goes by sea. 500
million containers are transported every year headed for the world’s
major hubs of consumption, such as Dubai.
Dubai
is one of the biggest construction sites in the world, a country where
the impossible becomes possible. Building artificial islands in the sea,
for example. Dubai has few natural resources, but with the money from
oil, it an bring millions of tons of material and people from all over
the world. It can build forests of skyscraper, each one taller than the
last, or even a ski slope in the middle of the desert. Dubai has no
farmland but it can import food. Dubai has no water but it can afford to
expend immense amounts of energy to desalinate seawater and build the
highest skyscrapers in the world. Dubai has endless sun but no solar
panels. It is the city of more is more, where the wildest dreams become
reality. Dubai is a sort of culmination of the Western model with its
800-meter high totem to total modernity that never fails to amaze the
world. Excessive? Perhaps. Dubai appears to have made its choice. It is
like the new beacon for all the world’s money. Nothing seems further
removed from nature than Dubai. Although nothing depends on nature more
than Dubai. The city merely follows the model of wealthy nations. We
haven’t understood that we’re depleting what nature provides.
What do we know of the marine world, of
which we see only the surface, and which covers three-quarters of the
planet? The ocean depths remain a secret. They contain thousands of
species whose existence remains a mystery to us. Since 1950, fishing
catches have increased fivefold, from 18 to 100 million metric tons a
year. Thousands of factory ships are emptying the oceans. Three-quarters
of fishing grounds are exhausted, depleted or in danger of being so.
Most
large fish have been fished out of existence since they have no time to
reproduce. We are destroying the cycle of a life that was given to us.
On the coastlines, signs of the exhaustion of stocks abound. First sign:
Colonies of sea mammals are getting smaller. Made vulnerable by
urbanization of the coasts and pollution, they now face a new threat:
famine. In their unequal battle against industrial fishing fleets, they
can’t find enough fish to feed their young. Second sign: Seabirds must
fly ever greater distances to find food. At the current rate, all fish
stocks are threatened with exhaustion. In Dakar, traditional net fishing
boomed in the years of plenty, but today, fish stocks are dwindling.
Fish is the staple diet of one in five
humans. Can we envision the inconceivable? Abandoned boats, seas devoid
of fish? We have forgotten that resources are scarce. 500 million humans
live in the world’s desert lands, more than the combined population of
Europe. They know the value of water. They know how to use it sparingly.
Here, they depend on wells replenished by fossil water,which
accumulated underground in the days when it rained on these deserts:
25,000 years ago. Fossil water also enables crops to be grown in the
desert to provide food for local populations. The field’s circular shape
derives
from the pipes that irrigate them around a central pivot. But there is a
heavy price to pay. Fossil water is a nonrenewable resource. In Saudi
Arabia, the dream of industrial farming in the desert has faded. As if
on a parchment map, the light spots on this patchwork show abandoned
plots. The irrigation equipment is still there. The energy to pump water
also. But the fossil water reserves are severely depleted. Israel
turned the desert into arable land. Even though these hothouses are now
irrigated drop by drop, water consumption continues to increase along
with exports. The once mighty river Jordan is now just a trickle. Its
water has flown to supermarkets all over the world in crates of fruit
and vegetables.
The Jordan’s fate is not unique. Across the planet, one major river in 10 no longer
flows into the sea for several months of the year. The Dead Sea derives
its name from its incredibly high salinity that makes all life
impossible. Deprived of the Jordan’s water, its level goes down by over
one meter per year. Its salinity is increasing. Evaporation, due to the
heat, produces these fine islands of salt evaporates beautiful but
sterile.
In Rajasthan, India. Udaipur is a miracle of water. The city was made possible by
a system of dams and channels that created an artificial lake. For its
architects, was water so precious that they dedicated a palace to it?
India risks being the country that suffers most from the lack of water
in the coming century. Massive irrigation has fed the growing population
and in the last 50 years 21 million wells have been dug. The victory
over famine has a downside, however. In many parts of the country, the
drill has to sink ever deeper to hit water. In western India, 30% of
wells have been abandoned. The underground aquifers are drying out. Vast
reservoirs will catch the monsoon rains to replenish the aquifers. In
dry season, women from local villages dig them with their bare hands.
(End of first part. Next..)
HOME (Text Version Part II)
(Continued from Part I )
Thousands
of kilometers away, 800 to 1,000 liters of water are consumed per
person per day. Las Vegas was built out of the desert. Millions of
people live there. Thousands more arrive every month. The inhabitants of
Las Vegas are among the biggest consumers of water in the world. Palm
Springs is another desert city with tropical vegetation and lush golf
courses. How long can this mirage continue to prosper? The Earth cannot
keep up. The Colorado River which brings water to these cities, is one
of those rivers that no longer reaches the sea. Even more alarmingly,
its flow is diminishing at source. Water levels in the catchment lakes
along its course are plummeting. Lake Powell took 17 years to reach
high-peak mark. Its level is now half of that. Water shortages could
affect nearly two billion people before 2025. Yet water is still
abundant in unspoiled regions of the planet, the wetlands.
These
wetlands are crucial to all life on Earth. They represent six percent
of the planet. Marshes are sponges that regulate the flow of water. They
absorb it in the wet season and release it in the dry season. The water
runs off the mountain peaks, carrying with it the seeds of the regions
it flows through. This process gives birth to unique landscapes, where
the diversity of species is unequaled in its richness. Under the calm
water lies a veritable factory where this ultimately linked richness and
diversity patiently filters the water and digests all the pollution.
Marshes are indispensable environments for the regeneration and
purification of water. These wetlands were always seen as unhealthy
expanses, unfit for human habitation. In our race to conquer more land,
we have reclaimed them as pasture for our livestock, or as land for
agriculture or building. In the last century, half of the world’s
marshes were drained. We know neither their richness nor their role.
All living matter is linked. Water, air, soil, trees. The world’s magic is right in front of our eyes. Trees
breathe groundwater into the atmosphere as light mist. They form a
canopy that alleviates the impact of heavy rains and protects the soil
from erosion. The forests provide the humidity that is necessary for
life. They are the mother and father of rain. The forests store carbon.
They contain more than all the Earth’s atmosphere. They are the
cornerstone of the climatic balance on which we all depend. Trees
provide a habitat for three-quarters of the planet’s biodiversity-that
is to say, of all life on Earth. Every year, we discover new species we
had no idea existed-insects, birds, mammals. These forests provide the
remedies that cure us. The substances secreted by these plants can be
recognized by our bodies. Our cells talk the same language. We are of
the same family.
Mangroves are forests that step out onto the sea. Like coral reefs, they are a nursery for
the oceans. Their roots entwine and form a shelter for the fish and
mollusks that come to breed. Mangroves protect the coasts from
hurricanes, tidal waves and erosion by the sea. Whole peoples depend on
them. Yet they were reduced by half during the 20th century. One of the
reasons for the ongoing disaster is these shrimp farms installed on the
mangroves’ rich waters. Ventilators aerate pools full of antibiotics to
prevent the asphyxiation of the shrimps, not that of the mangroves.
Since the 1960s, deforestation has
constantly gathered pace. Every year, 13 million hectares of tropical
forest an area the size of Illinois disappear in smoke and as lumber.
The world’s largest rain forest, the Amazon, has already been reduced by
20%. The forest gives way to cattle ranches or soybean farms.
Ninety-five percent of these soybeans are used to feed livestock
and poultry in Europe and Asia. And so, a forest is turned into meat.
When they burn, forests and their soils release huge quantities of
carbon, accounted for 20% of the greenhouse gases emitted across the
globe. Deforestation is one of the principal causes of global warming.
Thousands of species disappear forever. With them, one of the links in a
long chain of evolution snaps. The intelligence of the living matter
from which they came is lost forever.
Barely
20 years ago, Borneo, the fourth-largest island in the world, was
covered by a vast primary forest. At the current rate of deforestation,
it will have totally disappeared within 10 years. Living matter bonds
water, air, earth and the sun. In Borneo, this bond has been broken in
what was one of the Earth’s greatest reservoirs of biodiversity. This
catastrophe was provoked by the decision to produce palm oil, the most
consumed oil in the world, on Borneo. Palm oil not only caters to our
growing demand for food, but also cosmetics, detergents, and,
increasingly, alternative fuels. The forest diversity was replaced by a
single species-the oil palm. 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.
Soybeans, palm oil, eucalyptus
trees-deforestation destroys the essential to produce the superfluous.
But elsewhere, deforestation is a last resort to survive. Over two
billion people-almost a third of the world’s population-still depend on
charcoal.
In Haiti, one of the world’s poorest
countries, charcoal is one of the population’s main consumables. Once
the pearl of the Caribbean, Haiti can no longer feed its population
without foreign aid. On the hills of Haiti, only two percent of the
forests are left. Stripped bare, the soil no longer absorbs the
rainwater. With no vegetation and no roots to reinforce them, nothing
holds the soils back. The rainwater washes them down the hillsides as
far as the sea. Erosion
impoverishes the quality of the soils, reducing their suitability for
agriculture. In some parts of Madagascar, the erosion is spectacular.
Whole hillsides bear deep gashes hundreds of meters wide. Thin and
fragile, soil is made by living matter. With erosion, the fine layer of
humus, which took thousands of years to form, disappears.
Here’s one theory of the story of the
Rapa Nui, the inhabitants of the Easter Island, that could perhaps give
us a pause for thought. Living on the most isolated island in the world,
the Rapa Nui exploited their resources until there was nothing left.
Their civilization did not survive. On these lands stood the highest
palm trees in the world. They have disappeared. The Rapa Nui chopped
them all down for lumber. They then have to face widespread soil
erosion. The Rapa Nui could no longer go fishing. There were no trees to
build canoes. And yet the Rapa Nui formed one of the most brilliant
civilizations in the Pacific. Innovative farmers, sculptors, exceptional
navigators, they were caught in the vise of overpopulation and
dwindling resources. They experienced social unrest, revolts and famine.
Many did not survive the cataclysm. The real mystery of the Easter
Island is not how its strange statues got there. We know now. It’s why
the Rapa Nui didn’t react in time. It’s only one of a number of
theories, but it has particular relevance to us today.
Since 1950, the world’s population has
almost tripled. And since 1950, we have more fundamentally altered our
island, the Earth, than in all of our 200,000 year history. Nigeria is
the biggest oil exporter in Africa, and yet 70% of the population lives
under the poverty line. The wealth is there, but the country’s
inhabitants don’t have access to it. The same is true all over the
globe. Half the world’s poor live in resource-rich countries.
Our
mode of development has not fulfilled its promises. In 50 years, the
gap between rich and poor has grown wider than ever. Today, half of the
world’s wealth is in the hands of the richest two percent of the
population. Can such disparity be maintained? They’re the cause of
population movements whose scale we have yet to fully realize. The city
of Lagos had a population of 700,000 in 1960. That will rise to 16
million by 2025. Lagos is one of the fastest-growing megalopolises in
the world. The new arrivals are mostly farmers forced off the land for
economic or demographic reasons or because of the diminishing resources.
This is a radically new type of urban growth driven by the urge to
survive rather than to prosper. Every week, over a million people swell
the populations of the world’s cities.
One human being in six now lives in a
precarious, unhealthy, overpopulated environment, without access to
daily necessities, such as water, sanitation or electricity. Hunger is
spreading once more. It affects nearly one billion people.
All over the planet, the poorest scrabble to survive on scraps, while we continue
to dig for resources that we can no longer live without. We look
farther and farther afield, in previously unspoiled territory and in
regions that are increasingly difficult to exploit. We’re not changing
our model. Oil might run out? We can still extract oil from the tar
sands of Canada. The biggest trucks in the world move thousands of tons
of sand. The process of heating and separating bitumen from the sand
requires millions of cubic meters of water. Colossal
amounts of energy are needed. The pollution is catastrophic. The most
urgent priority, apparently, is to pick every pocket of sunlight. Our
oil tankers are getting bigger and bigger. Our energy requirements are
constantly increasing. We try to power growth like a bottomless oven
that demands more and more fuel.
It’s all about carbon. In a few decades,
the carbon that made our atmosphere a furnace, and that nature captured
over millions of years, allowing life to develop, will have largely been
pumped back out. The atmosphere is heating up. It would have been
inconceivable for a boat to be here just a few years ago.
Transport, industry, deforestation, agriculture. Our activities release
gigantic quantities of carbon dioxide. Without realizing it, molecule
by molecule, we have upset the Earth’s climatic balance. All eyes are on
the poles, where the effects of global warming are most visible. It’s
happening fast-very fast. The Northwest Passage that connects America,
Europe and Asia via the pole is opening up. The Arctic ice cap is
melting. Under the effect of global warming, the ice cap has lost 40% of
its thickness in 40 years. Its surface area in the summer shrinks year
by year. It could disappear before 2030. Some predictions suggest 2015.
Soon these waters will be free of ice several summer months a year. The
sunbeams that the ice sheet previously reflected back now penetrate the
dark water heating up. The warming process gathers pace. This ice
contains the records of our planet. The concentration
of carbon dioxide hasn’t been so high for several hundred thousand
years. Humanity has never lived in an atmosphere like this. Is excessive
exploitation of our resources threatening the lives of every species?
Climate change accentuates the threat. By 2050, a quarter of the Earth’s
species could be threatened with extinction. In these polar regions,
the balance of nature has already been disrupted.
Off the coast of Greenland, there are
more and more icebergs. Around the North Pole, the ice cap has lost 30%
of its surface area in 30 years. But as Greenland rapidly becomes
warmer, the freshwater of a whole continent flows into the salt water of
the oceans. Greenland’s ice contains 20% of the freshwater of the whole
planet. If it melts, sea levels will rise by nearly seven meters.
But
there is no industry here. Greenland’s ice sheet suffers from
greenhouse gases emitted elsewhere on Earth. Our ecosystem doesn’t have
borders. Wherever we are, our actions have repercussions on the whole
Earth. The atmosphere of our planet is an indivisible whole. It is an
asset we share. On Greenland’s surface, lakes are appearing on the
landscape. The ice cap has begun to melt at a speed that even the most
pessimistic scientists did not envision 10 years ago. More and more of
these glacier-fed rivers are emerging together and burrowing through the
surface. It was thought the water would freeze in the depths of the
ice. On the contrary, it flows under the ice, carrying the ice sheet
into the sea, where it breaks into icebergs. As the freshwater of
Greenland’s ice sheet gradually seeps into the salt water of the oceans,
low-lying lands around the globe are threatened.
Sea levels are rising. Water expanding as
it gets warmer caused, in the 20th century alone, a rise of 20
centimeters. Everything becomes unstable. Coral reefs, for example, are
extremely sensitive to the slightest change in water temperature. Thirty
percent have disappeared. They are an essential link in the chain of
species. In the atmosphere, the major wind streams are changing
direction. Rain cycles are altered. The geography of climate is
modified. The inhabitants of low-lying islands here in the Maldives, for
example, are on the front
line. They are increasingly concerned. Some are already looking for
new, more hospitable lands. If sea levels continue to rise faster and
faster, what would major cities like Tokyo, the world’s most populous
city, do? Every year scientists’ predictions become more and more
alarming. Seventy percent of the world’s population lives on coastal
plains. Eleven of the 15 biggest cities stand on a coastline or river
estuary. As the seas rise, salt will invade the water table, depriving
inhabitants of drinking water. Migratory phenomena are inevitable. The
only uncertainty concerns their scale.
In Africa, Mount Kilimanjaro is
unrecognizable. Eighty percent of its glaciers have disappeared. In
summer, the rivers no longer flow. Local peoples are affected by the
lack of water. Even on the world’s highest peaks, in the heart of the
Himalayas, eternal snows and glaciers are receding. Yet these glaciers
play an essential role in the water cycle. They trap the water from the
monsoons as ice and release it in the summer when the snow melts. The
glaciers of the Himalayas are the source of all the great Asian
rivers-the Indus, Ganges, Mekong, Yangtze Kiang. Two billion people
depend on them for drinking water and to irrigate their crops as in
Bangladesh. On the delta of the Ganges and Brahmaputra, Bangladesh is
directly affected by the phenomena occurring in the Himalayas and at sea
level. This is one of the most populous and poorest countries in the
world. It is already hit by global warming. The combined impact of
increasingly dramatic floods and hurricanes could make a third of its
landmass disappear.

(Continued from part II)
When populations are subjected to these
devastating phenomena, they eventually move away. Wealthy countries will
not be spared. Droughts are occurring all over the planet. In
Australia, half of farmland is already affected. We are in the process
of compromising the climatic balance that has allowed us to develop over
12,000 years. More and more wildfires encroach on major cities. In
turn, they exacerbate global warming. As the trees burn, they release
carbon dioxide. The system that controls our climate has been severely
disrupted.
The
elements on which it relies have been disrupted. The clock of climate
change is ticking in these magnificent landscapes. Here in Siberia and
elsewhere across the globe it is so cold that the ground is constantly
frozen. It’s known as permafrost. Under its 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.
We have created phenomena we cannot control. Since our origins, water,
air and forms of life are intimately linked. But recently, we have
broken those links.Let’s face the facts.We must believe what we know. All that we have just seen is a reflection of human behavior. We have shaped the Earth in our image. We have very little time to change. How can this century carry the burden of nine billion human beings if we refuse to be called to account for everything we alone have done?
20% of the world’s population consumes 80% of its resources
The world spends 12 times more on military expenditures than on aid to developing countries.
5,000 people a day die because of dirty drinking water
1 billion people have no access to safe drinking water
Nearly 1 billion people are going hungry
Over 50% of grain traded around the world is used for animal feed or bio fuels
40% of arable land has suffered long-term damage
Every year, 13 millions hectares of forest disappear
One mammal in 4, one bird in 8, one amphibian in 3 are threatened with extinction
Species are dying out at a rhythm 1,000 times faster than the natural rate
Three quarters of fishing grounds are exhausted, depleted or in dangerous decline
The average temperature of the last 15 years have been the highest ever recorded
The ice cap is 40% thinner than 40 years ago
There may be at least 200 million climate refugees by 2050
The cost of our actions is high. Others pay the price without having
been actively involved. I have seen refugee camps as big as cities
sprawling in the desert. How many men, women and children will be left
by the wayside tomorrow. Must we always build walls to break the chain
of human solidarity, to separate peoples and protect the happiness of
some from the misery of others?It’s too late to be a pessimist. I know that a single human can knock down every wall. It’s too late to be a pessimist. Worldwide, four children out of five attend school. Never has learning been given to so many human beings. Everyone, from richest to poorest, can make a contribution. Lesotho, one of the world’s poorest countries, is proportionally the one that invests most in its people’s education. Qatar, one of the world’s richest states has opened its doors to the best universities. Culture, education, research and innovation are inexhaustible resources. In the face of misery and suffering, millions of N.G.O’s prove that solidarity between peoples is stronger than the selfishness of nations. In Bangladesh, a man thought the unthinkable and founded a bank that lends only to the poor. In barely 30 years, it has changed the lives of 150 million people around the world. Antarctica is a continent with immense natural resources that no country can claim for itself, a natural reserve devoted to peace and science. A treaty signed by 49 states has made it a treasure shared by all humanity. It’s too late to be a pessimist. Governments have acted to protect nearly two percent of the world’s territorial waters. It’s not much but it’s two times more than 10 years ago. The first natural parks were created just over a century ago. They cover over 13% of the continents. They create spaces where human activity is in step with the preservation of species, soils and landscapes.
This harmony between humans and nature can become the rule, no longer the exception. In the United States, New York has realized what nature does for us. These forests and lakes supply all the drinking water the city needs. In South Korea, the forests have been devastated by war. Thanks to a national reforestation program, they once more cover 65% of the country. More than 75% of paper is recycled. Costa Rica has made a choice between military spending and the conservation of its lands. The country no longer has an army. It prefers to devote its resources to education, ecotourism and the protection of its primary forest. Gabon is one of the world’s leading producers of wood. It enforces selective logging. Not more than one tree every hectare. Its forests are one of the country’s most important economic resources but they have the time to regenerate. Programs exist that guarantee sustainable forest management. They must become mandatory. For consumers and producers, justice is an opportunity to be seized. When trade is fair, when both buyer and seller benefit, everybody can prosper and earn a decent living. How can there be justice and equity between people whose only tools are their hands and those who harvest their crops with a machine and state subsidies?
Let’s be responsible consumers. Think about what we buy. It’s too late to be a pessimist. I have seen agriculture on a human scale. It can feed the whole planet if meat production doesn’t take the food out of the people’s mouths. I have seen fishermen who take care of what they catch and care for the riches of the ocean. I have seen houses producing their own energy. 5,000 people live in the world’s first ever eco-friendly district in Freiburg, Germany. Other cities partner the project. Mumbai is the thousandth to join them.
The government of New Zealand, Iceland, Austria, Sweden and other nations have made the development of renewable energy sources a top priority. I know that 80% of the energy we consume comes from fossil energy sources. Every week, two new coal-fired generating plants are built in China alone. But I have also seen, in Denmark, a prototype of a coal-fired plant that releases its carbon into the soil rather than the air. A solution for the future? Nobody knows yet. I have seen in Iceland an electricity plant powered by the Earth’s heat-geothermal power. I have seen a sea snake lying on the swell to absorb the energy of the waves and produce electricity. I have seen wind farms off the coast of Denmark that produce 20% of the country’s electricity. The U.S.A., China, India, Germany and Spain are the biggest investors in renewable energy. They have already created over two and a half million jobs. Where on Earth doesn’t the wind blow? I have seen desert expanses baking in the sun.
Everything on Earth is linked and the Earth is linked to the sun, its original energy source. Can humans not imitate plants and capture its energy? In one hour, the sun gives the Earth the same amount of energy as that consumed by all humanity in one year. As long as the Earth exists, the sun’s energy will be inexhaustible. All we have to do is stop drilling the Earth and start looking to the sky. All we have to do is learn to cultivate the sun. All these experiments are only examples that they testify to a new awareness. They lay down markers for a new human adventure based on moderation, intelligence and sharing.
It’s time to come together. What’s important is not what’s gone, but what remains. We still have half the world’s forests, thousands of rivers, lakes and glaciers and thousands of thriving species. We know that the solutions are there today. We all have the power to change. So what are we waiting for?
IT’S UP TO US TO WRITE WHAT HAPPENS NEXT
TOGETHER
