Water and the future of life on earth | DW Documentary

-Water is the foundation, the source
and the mechanisms that govern life but also govern the whole biosystem
and the climate of the blue planet. -Our groundwater is a treasure. It’s
a miracle. Somehow, it’s a miracle. -I spend more than a million dollars
a year on electricity to pump water. -We have a larger impact
on the planet than ever before. The climate, the water, the
land, biodiversity, the oceans. -The cycle of water, and being
able to understand that, is one of the most critical questions we have to
deal with today in a changing climate. -It is dangerous hydrological
climate extremes that are going to be threatening
ecological and human values. -Eventually, we cook ourselves,
as a frog in warm water. It cooks before it realizes that the water
is so hot, that it’s going to die. -So we really have it in our hands
now to understand. So that we can sustain the health
of the human population. Water is the foundation of all life as
we know it. But itís the most wasted natural resource, reflecting man’s
intense and short time on Earth. Water is life. We measure it in drinking water, but
itís much more than that. Water must be present in all of the planetís
systems for it to be in balance. -You can think of water as Earth’s blood
supply. It flows through the landscape supplying nutrients
to nature and plants. Water is also the source
of human life and society. -If we manage the water as we do now,
where we use it, pollute it and then try to dispose of it, with very serious
consequences… That system is not sustainable. Under that current system
of water use, we are running out of water. We are losing more and more
useful water. The association between the imbalance of the
water cycle and climate-related problems is bigger than
what most people are aware of. We are also not taking care of our
most important substance. We just regard it as any liquid. Still: water is
the very foundation of life itself. -Water was, to a large degree, formed
as the Earth took shape. It’s a chemical compound of two hydrogen atoms
and one oxygen atom. It’s a simple compound, but with
very distinct qualities. -Water is one of the universe’s
most unique materials. It has completely unexpected
and unique properties. -We have it as vapour. We have it as liquid
water in rivers, lakes and the oceans. We have it as snow and
ice in its coldest phase. Ninety-seven percent of the planetís
water is saline and is found in the oceans. The remaining three percent is
freshwater, of which more than half is contained in glaciers. Only about
one percent is available to us. Nevertheless we act as if
water is an endless resource. -Water is something that we all take for
granted until it’s not there. We just take it for granted youíre going to turn on
the tap in a hotel room or another city and there’s going to be water there. I saw
a study that the majority of people in the state don’t know where
their water comes from. They just know the
water bill when it comes. We don’t understand the value of
water. Nor that the hydrosphere is crucial for the ecosystems that we depend
upon. And the magic in that everything is created in the meeting
between sun and water. -Solar energy cleanses seawater and
produces freshwater. Nature is constantly cleansing water in the water cycle.
Rainwater is clean. But unfortunately chemicals can be dissolved
into it in the atmosphere. -The amount of freshwater on the planet
depends effectively on evaporation and transpiration. Because, you see, as water
evaporates, it leaves behind all the salts and the pollutants that may be
in the oceans. It just goes up as pure water vapour. So,
it regenerates freshwater. -At a certain level and temperature water
vapour condenses. Mostly into ice particles or snowflakes that form clouds.
When the clouds get heavy enough, to put it simply,
you get precipitation. Precipitation. Rain and snow that
falls in large volumes to hardly at all. For water molecules to form drops, itís
been discovered that aerosols are needed. Small ice and salt crystals which
are the starting point for condensation. -One million of these cloud microdroplets
need to be coalesced into each raindrop for it to be heavy enough and large
enough to fall out of the air under gravity and back to the land. This nucleation
of these water droplets is a key balancing process in
nature in driving rainfall. But there are other aerosols that are
important for creating raindrops. Bacteria. Through the evaporation of trees, specific
bacteria end up in the atmosphere where they bind water vapour and create
drops. The bacteria return to earth with the rain that they
themselves created. -We have precipitation that comes down
onto the surface of Earth, either into the oceans or it goes onto the land. If it goes
onto the land, then some of it percolates down into the ground. Some of it evaporates
back into the atmosphere. Some of it goes into the plants. Some of
it runs down the hill right away. If it falls as snow it stays as
a mountain reservoir of water. And it doesn’t move out
of its system very quickly. -So thereís just this constant exchange
of water moving across the surface, under the surface, into the atmosphere,
and back down onto the surface. -When the rain falls down, and it becomes
groundwater. It goes slowly deeper and takes up minerals. Here in Brabant we
have groundwater at about 80 meters deep and about 200 meters deep. It’s coming
from Belgium and it travels with a speed of 20 meters per year. Very slowly. It took
about 10,000 years for it to come from Belgium to here. We use it for
drinking water and to irrigate our crops. It’s also known as fossil water. Depending
on the bedrock, age may vary. But most groundwater reservoirs are
ancient and were created long before humanity
appeared on earth. Itís formed by rainfall that dissolves
minerals and nutrients. It’s the best and purest of all water. And the most important
water resource for us and the ecosystems. -If you pump groundwater and every
year you’re using it without it being replenished, then the groundwater is
going to decrease. How far can it go? -Do you know how much water we pump?
Two billion – with a îBî – gallons a year. -I spend more than a million dollars
every year on electricity to pump water. Itís the land of the big acreages. Frahm
Farmland grows animal feed such as corn and grain on 14,000 hectares. These
cultivations are possible thanks to one of the world’s largest systems of
fossil groundwater being available. Ogallala Aquifer supplies
eight states and about 2.5 million inhabitants with water.
But the levels are dropping. -Unfortunately we’ve pumped in this
area at least 30 percent of the aquifer. We’ve lowered it. As we do that, the
well is more pressed to give up the water. A lot of wells only pump half of what
they did when they were first developed. -There might be enough water for
50 to 70 years. Then it will be gone. Groundwater is being
overused all over the world. Large-scale operation and monoculture cost
water. Itís not only the farms in Kansas that consume. About 70 percent of the
planetís freshwater goes to cultivation and food production. Do the
large-scale monocultures drain the groundwater systems to
dangerously low levels? -Will the Ogallala Aquifer ever be
drained? It’s being drained right now. I’ve heard people use the word ‘mined’.
Because itís something thatís taken out of the ground and not put back. As if
we were mining gold or pumping oil. It’s a mining
operation. -Thousands of years were required
to create these groundwater supplies. And so pumping those out of there in
order to get back to the aquifer level that we had before we started pumping
them…It’s going to take a long time. -This creates enormous problems in
the next couple of decades. Because the agriculture that depends on
that water is designed to collapse. We extract more than what is replenished.
We’re draining the worldís most important water resources. But there is another, very
important water existing in environments that we hardly think of. The soil water:
a hidden resource found in the soil, which is essential for
life in the biosphere. -The soil which covers 29 percent or 13
billion hectares of land surface is really a big sponge. Depending on
the quality of that sponge, they can hold up to 50 percent
of their volume in water. -A significant amount of water is stored
within the soil sponge and as groundwater. It’s, in fact, more than the water that
we see in the form of rivers and lakes. In order for soil and cultivated land
to function and supply water it must be healthy and alive. Micro-organisms and
organic matter preserve water. In a time when rainfall is unpredictable,
this is extremely important. -The critical thing is that what happens
to every raindrop that falls on the earthís surface. Does it infiltrate and get
retained, in a form and location so that it’s valuable to plant growth? Or does it
run off, erode soils and biosystems and then get lost into the ocean? The
difference whether it infiltrates or runs off depends on the Earth’s soil
carbon sponge. Whether that sponge can have the porosity and the permeability to
absorb that water and then feed it into the deeper soil horizons – which
are our in-soil resevoirs – because it’s that water that governs
life in the biosystem. -The industrial form of farming
deforms the ability of soil to soak water. It loses the humus. You have a very compact
soil on top of that which is dry. Heavy rain or other precipitation is left on
the surface. The soil is hydrophobic. The soil sponge is leaving us. The groundwater
recharge is leaving us because of that. We’re flushing the vital component
of life away from ourselves. It comes down to impoverished soil that
has lost its capacity to infiltrate and its ability to hold water. At
the same time we drain and divert the water
from its natural cycle. We urbanize the planet through industrial
development and the soil horizon that was an important water reservoir is being
sealed under concrete and infrastructure. -Cities are growing and we are asphalting
the planet. We tarmac the farmland. We isolate farmland from the water cycle.
Drainage diverts surface water into rivers and lakes. And it’s often quite polluted.
Water from heavy rainfall has nowhere to go. It runs straight into
the sea. It isn’t put to use. It doesn’t replenish the
groundwater, it’s not a resource. -If we drain the water, we decrease
the wetland, we decrease the biodiversity, we decrease the water infiltration,
so we decrease the water cycle. We consume groundwater and create
hydrophobic soils. We isolate the soil under hardened lands, and the precipitation
is diverted. This means less water on the continents and declining
groundwater systems. And the consequences of
this are extensive. -Dehydration is the long-term
process of less and less water reaching the groundwater.
That makes it so trees and other plants can’t reach the
groundwater any more. -The impact is actually quite horrific.
Eventually we cook ourselves as a frog in warm water. It cooks before it realises
that the water is so hot that it is going to die. With every drop that
we flush away, less water is coming in. This is how desertification
comes in slowly but surely. -Different regions are experiencing already
significant aridification. Losing 20 to 30 percent of their rainfall and risk
turning more and more into deserts. -When nature withers from thirst, it gets
warmer. More solar energy, and neither water nor vegetation can help the cooling
of the soil. Our consumption and use of water resources thus have a direct impact
on global temperature and our climate. -It is water that in a sense governs
95 percent of the heat dynamics of the blue planet. For the last four
billion years it is water that has actually regulated the
climate. It’s the different water processes that
govern these dynamics. -Our research shows that it’s not just a
matter of climate change. Things we do at ground level have an impact. Intensified
farming to increase the yield per square meter; or if the acreage increases or we
use more water we increase transpiration. -Up to now we have been so focused
– exclusively almost – on the CO2 concentration in the atmosphere that
has obviously gone up abnormally. We have assumed that the CO2 rise – because it is
a greenhouse gas – has caused the planet to heat up. Certainly that is a key
contributing factor. But a far, far bigger factor has been the changes we have
been making to the Earth’s hydrology. Not only do we release previously-reserved
water that increases the amount of water vapor in the atmosphere, but we also
contribute to global warming by large-scale monocultivation and increasing
urbanization. We create islands of heat that
repulse clouds and rainfall. -If we have a green vegetated landscape
with transpiration cooling, the soils rarely get above 20 degrees centigrade even
in tropical regions. Conversely, where we have bare, exposed soil subject to the
incident solar radiation, especially soil that hasn’t got water…that soil, or
asphalt or concrete or that surface can often heat up to 60 degrees centigrade
or above. Which means a profoundly more infrared heat is radiated from
hot surfaces compared to cold surfaces. -Monocultures and industrial farming do
bring along this phenomenon of heat island. Because from one day to another a large
area is harvested. And from one day to another you switch on in the snap
of finger a nuclear power plant that’s radiating upwards. So this is how
the agriculture and the industrial form of agriculture
deforms the weather. -A warm atmosphere can contain more
water than a cold one. We can safely assume that hurricanes and
ensuing severe rainfall will become more frequent. And
they will intensify. We water the atmosphere with freshwater.
And with rising temperatures, the hydrological cycle is affected. It’s
difficult to observe, but imbalance contributes to weather processes
that affect every part of the planet. -It is dangerous, hydrological climate
extremes that are going to be impacting, intensifying and really threatening a
whole lot of different ecological and human values. These are hurricanes, storms,
floods, aridification, droughts, wildfires. And itís these hydrological
extremes that kill human beings. -The climatic effect on the water leads
to disastrous floods and droughts. The long-term effects can change the conditions
for a large number of societies on Earth. -Could these extremes be the norm in 50
years? How are we going to handle them? Extreme will become the norm. Donít we
already see it today? That environments change for the worse for all living
beings. What will our existence look like in the future? It seems
uncertain with a changing world view. -We can do okay when we get droughts and
wet periods and it’s minor. But if it comes four, five, or six years of intense
drought. Or, as in the Colorado River Basin now, we’re in 18 years of drought.
We have 40 million people in the state of California that are strongly dependent
on that water resource. Where are they going to go if it goes too dry? People
donít survive those, they have to move. Civilizations don’t
survive those. Lack of freshwater is a reality in many
parts of the world. But that is far away, not here. Water is also consumed through
direct consumption and as a commodity in our trading systems. It’s a
virtual, invisible water that hides primarily in products linked
to cultivation and agriculture. -A lot of goods are imported from
regions where thereís a shortage of water. A lot of water flows from
arid areas to areas where water resources
are already plentiful. -We tend to think of water as a
local resource. But trading goods means we have an impact on each
other. There’s water in everything. Everything contains water, from textiles
to cut flowers. Our lifestyles are costly. And we exhaust water-stressed nationsí
access and right to safe, clean water. It’s not only about products. Half
of the food we consume is imported. -Thirty to 40 percent of all foodstuffs are
never consumed. They’re ruined by poor storage or poor handling, or just thrown
away. The equivalent to the US production of foodstuffs is just thrown away. And
that means weíre also wasting water. We consume large volumes of water
through overproduction and discarded food. Things which donít just waste
resources but also generate pollution. -Our water reflects our behaviour.
Because sooner or later everything we do or use or have
ends up in the water. -The chemical footprint that weíre
finding in rivers and lakes is definitly a reflection of how society interacts with
water. When weíre taking samples near a city itís more dominated by detergents. In
an agricultural area itís more dominated by pesticides. Near a mining area you
have a lot of heavy metals. We can clearly see that human activities are driving
the chemical footprint in a river or lake. -Of the agricultural use of water in
Kansas, the majority would be for watering crops. One concern, as water filters
down to the aquifer, is water quality. The one big concern is
leaching of nitrogen fertilizer. -In this country we have a lot of
livestock, so we have a problem with far too much manure. We see that in our
groundwater and also in the ditches and the canals. I think nitrate in the groundwater
is a problem for biodiversity in the soil. -The nitrogen leaches down into the
aquifer which contaminates it for drinking. It’s not just irrigation water that can
do that. One of the big sources is run-off from feedlots. Kansas is the largest
meatpacking state in the United States. There are areas around feed lots where
the water is too contaminated to drink. Itís not just the fertilizers from the
meat industry that affect water resources negatively and pollute groundwater.
The water that naturally gives us minerals and nutrition also gives
us completely different substances. -Water is an excellent
solvent. It absorbs pollution so that it becomes
part of the cycle. -There are all sorts of pollutants in
different parts of the water system. Cleaning it up is energy and
cost -intensive. The question is: ‘How much of it
can we cleanse out?’ The pollutants are a big problem.
There are many unrecorded issues. We don’t carry out
tests everywhere. We dilute the chemicals in the belief
that the consequences will be smaller. But despite our efforts to
minimize risks, the effects of our usage of chemicals are
extensive and already noticeable. -The drugs in surface water are
painkillers, blood pressure medicines, diabetes and antiepileptics. All sorts
of medicines we use daily. Antibiotics. And they have different effects
on the ecosystems in the water. Our naive relationship to chemicals
and chemically manufactured products is unsustainable. This makes large volumes
of the available water on earth useless. And in addition
we have plastic. -There are plastics in tap water. There are
plastics even more often in bottled water. We’re drinking plastics. Each day,
per square meter indoors more than 300 plastic microparticles collect. Leave a
glass of water on the table, and you’ll be exposed to them. They’re in the air,
water and food. The impact on humans has yet to be studied. We’re starting
to understand the impact on animals and organisms. But
we don’t yet know the full effects. Plastic is everywhere. And in places where
people often meet, artifical turf, small plastic fragments and granules make
their way down the sewage systems. There is also the possibility that microparticles
attract and collect chemicals. What happened? The water cycle
is everywhere. Cleaning, filtering, drinking water, rainfall, climate balance.
But it has been downgraded to a consumable and a transport system for pollution.
The planet’s blood stream is draining. And surely this reflects on us as humans,
and our short and intense time on earth. -Over the last 200 years, that is the
period when humans have come to have an influence on the Earth’s system.
Industrialization itself is not all bad. It’s just how we capture what we’re
doing and understand how we’re influencing ourselves. Influencing our
ecosystem and our water supply. -Biodiversity is like a pyramid.
At the top there’s the human being. If biodiversity disappears, the human being
disappears too. It’s important to protect the biodiversity. Also, there’s a big
connection with water. All of this area plays a role in water capture. There’s
good water filtration by the peat moss. This area is important to reduce global
warming. A wet, peaty area can capture ten times more CO2 greenhouse
gas, than other soil. It’s very important to preserve this
place to reduce global warming. -We have to take carbon out of the
air. It was put there from our degradation of our landscape. We’ll put that back
into our soils to rebuild the sponge so we can rebuild the hydrology. Two to three
percent carbon added into the soil can create structural regeneration effects.
It can add voids and surfaces into that soil matrix and
really rebuild healthy soils. Through photosynthesis carbon can be
bound in the soil, letting nature transform carbon dioxide into a rich soil, with
micro-organisms that make the soil healthy and water-retaining. This way
the climate, the water balance, and our arable land will
be positively affected. -In the spring, when the photosynthesis
turns on you see a significant drop in terms of carbon dioxide in the atmosphere.
Which goes down as the photosynthisis progresses through the summer. When
we hit fall, and everything’s harvested again there’s an increase in the
concentration of carbon dioxide. This shows the magnitude of the impact
that photosynthesis has on the amount of carbon
dioxide in the atmosphere. -Soils are also fundamental because it’s
the only point of agency, the only point of influence we humans have on the
Earth’s climate, hydrology, and our future. We can’t change the oceans
or the ice caps. We can change the atmosphere to some extent but
the real point of agency is the sponge. There is clearly an overconsumption
of the water resources on the planet. A consumption that effects the climate,
the ecosystems, and everyone on Earth. We have to end the idea that freshwater
is infinite. And we have to understand the value of the hydrological
cycle as well as the solutions that nature has already
developed for the climate. -We are not using the systems and the
lesson that nature provides us. We think we’re above nature. We’ve lived the
last century with delusions that we can fix things technologically. The reality is
coming that there are limits. There is an imperative for regeneration. Hopefully
we will have the wisdom to now say: Let’s work with nature. Let’s
get our boot off her throat and let her breathe. Let’s help her to
actually regenerate these biosystems. -We should be more aware of the
fact that our groundwater is a treasure. And use it with respect, as you treat
a treasure. It’s a miracle. Somehow itís a miracle. But we are so used to it
that we can’t see the miracle any more. -What society has to do now is
monitor how we use our water resources. So that we avoid overuse
and too much pollution. Which would ruin the
basis of our existence. -We have it in our hands now to understand
how these water supplies are changing: these water fluxes as well as the
interaction with the climate are changing. So that we can sustain
the standard of living and the health of the
human population. We are one. Us, the water, and nature.
We need to rethink. To stop polluting and draining and instead, retain the water
on the continents. Be conscious of carbon storage, and think of cultivation methods
that replenish the water in the soil, in the ecosystems and in the groundwater.
We must think of photosynthesis and nature’s own climate control. But we
must also understand that balance in the water cycle is a fundamental
condition for our future. -Clearly, we have messed up the show.
We have degraded these lands, the sponges, our in-soil reservoirs, hydrology…
The cooling of the planet. Nature will always be here. Nature will restore
these biosystems. The only question is: Will we help her do that? Or let
her do it by herself after we are gone?

    So many verses in the Quran, Allah has mentioned and emphasized the importance of water, as the source of life and HIS mercy too. And in some areas, HE presents a rhetoric question of: What if I withheld it from pouring? I cannot present all the verses, but if anyone is interested go do research on verses of Quran that mentions about water. However, I applaud this video and channel. Exemplary work you undertake. In one verse of the Quran, Allah tells us NOT to destroy the good Earth after perfect creation of all systems. In fact one of the reasons of our creation is to be custodians.

    The Matrix, Agent Smith: Every mammal on this planet instinctively develops a natural equilibrium with their surrounding environment, but you humans do not. You move to another area, and you multiply, and you multiply, until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet. You are a plague.

  46. Gemcitysoles

  47. Mark IT Geek

    Somebody needs to figure out how to do mass-scale, cheap, effective ocean water desalination. I know plenty of people and companies are working on it… hopefully, they have some unforseen breakthrough, and it becomes possible, soon. Imagine being able to pump billions of gallons, thru this desalination planet, and then inland, to anywhere more water is needed. It would be an incredible achievement for humanity. Then, there would be an endless supply of good, clean water for every imaginable purpose.

    I'm watching this in Australia, at the moment it is raining (Drought Bushfires, & flood are synonymous in Australia) at the moment our storage dams are nearly full. BTW the Climate has always changed, I hope you're NOT going to build up to a push for a carbon tax?? The "Grave danger" at the moment is Corona virus. Just watched a bit more, Sadly I was correct in my suspicions. Just another doomsday cult, wake up to yourselfs hydrological BS. ! Stay safe.

  53. David Heinzen

    This video is a waste of time. We already know all this from first freaking grade. Why do you people keep sugar coating whats being done to this planet. You guys got to get a clue!! Most of the damage that is being done to the planet can not be repaired by a bunch of hand holding, kumbiya bullshit. The old guy with the green teeth is just a joke, wheel his ass back to the home.

  54. Niklas

    Are some of these clips from a swedish documentary or did you interview them for this one? 🙂
    Nice doc aswell. we HAVE to take care about our water, its more important than anything else

  55. Robustus

    Does our species do anything beneficial?


    This is why Covid19 was made, and there is going to be another one coming soon because this planet is over populated, time to cull the masses.

    Earth temperatures were remarkably stable and constant during the Holocene period until humans began mining fossil fuels and using them as a source of energy for the industrialization of the planet. The Holocene equilibrium has been destroyed by CO2 emissions, a fact which the scientists in this documentary evaded, deliberately, it seems to me. The hydrologist from Australia was especially culpable. He attributes the problem of the disappearance of the reserves of ground water and the degradation of the soil, to pollution arising from unsustainable agricultural practices, etc. He may be an excellent microbiologist but he his understanding is seriously out of alignment with the reality of the science of CO2 emissions as the principle source of global warming. It is wishful thinking on his part to plead for restoration of the hydrological cycle, while conveniently avoiding the thorny question of the status quo with regards to fossil fuel emissions. Water is a great subject for a documentary, and although this one is well done, it is deeply flawed at the same time.

    I wonder what is wrong with me that I have more compassion for the animals who have no part of this destruction of the world than I do for the humans who are causing most of it?

    When the Dinosaurs and huge vegitation grew, it Never rained a drop!

    I seriously think we should strap Pres. Trump down to a chair, tape his eyes open, and make him watch documentaries like this. He really has no idea of what is actually going on on the planet as a whole. His denial of events is clearly a result of a sheltered rich family life, with no regards for any one other than himself. What a waste of a presidential appointment.

  79. Michael Pearce

    Do you actually believe that spraying chemicals into the atmosphere for global dimming isn't going to effect the amount of evaporation that takes place. Those particles that holds a water in the clouds. Could that be part of the reason for the heavy rains that cause flooding?

    There are several ways the human race might go extinct: climate change, loss of usable groundwater, loss of insects for fertilizing crops, global temperature too high to grow food to scale, a deadly virus or bacteria coming from the melting permafrost, or nuclear annihilation. The interesting thing is all of these paths of possible extinction scenarios seem to be converging on a point in the not too distant future. The end is not going to be pretty.

  82. Mr x

    As a last thought my friends, do we now live on a disposable planet,? How can we even thing of terraforming another planet to suit our needs when we fail to take care of the one we now live on? Perhaps we are becoming the scourge of the universe, by using up any and all natural resources we can find to perpetuate an unsustainable life style. Disposable earth, now that is a concept for any major corporation. With the far right leading the way, we may be well on our way to solving our population problem with pollution and over use of limited resources.

    Thing is. Yes there is not enough fresh water. But ocean water can be turned into drinkable water. It's just about that man made thing called money. Ruins everything.
