6:15 am
you're watching the news i'm told me all going but then next up is a documentary film about how the growing scott city of water is posing a threat to human lives you know while you can catch up with all the latest news and information on our website it's called thanks for joining us. love. to go beyond. the stories that matter to the. country. whatever it takes. to go running to cut explain further the good job you made for
6:16 am
mines. water is the foundation the source and the mechanisms of the government wife but also govern the whole bio system and the climate of the blue planet. around water is their trash. it's a miracle. somehow it's a miracle. i spend more than a $1000000.00 every year on electricity to pump water. for that we have a larger impact on the planet than ever before the climate the water and the land biodiversity the ocean city hall but. the cycle of water and being able to understand that this one of the most critical questions that we have
6:17 am
to deal with today in a changing climate and. it is dangerous hard to logical climate extremes that are going to be threatening a whole lot of different ecological and human values. and eventually we called ourselves those beasts for all you know why water it of course and before you realize it's due to water salt that's going to die. so we really have it in our hands bound. 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 it's the most wasted natural
6:18 am
resource reflecting man's attempts in short time on our. water is life. we measure it in drinking water but it's much more than that. water must be present in all of the planet systems for it to be a balance. you can think of water as her blood supply. flows through the landscape supplies nutrients to nature and plants. because. water is also the source of human life and society. and. if we manage the water as we do now where we use that polluted air and then
6:19 am
try to dispose of it with very serious consequences that system is not sustained. and that current system. we have 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. to a large degree formed as the earth to shape. it's a chemical compound of 2 hydrogen atoms and one oxygen as him it's
6:20 am
a simple compound but with very distinct qualities. water is one of the the universe's most unique materials it has completely unexpected unique properties we have it as a vapor we have it there as liquid water running down the rivers and lakes and in the oceans we have it as snow and ice in its coldest days. 97 percent of the planet's water sailin and found in the oceans the remaining 3 percent is fresh water 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.
6:21 am
with water something that we all take for granted until it's not there. we just take it for granted no wonder you go we're going to turn the tap in the hotel room or another city that there's going to be water there. i saw say that the majority of the people in the state don't know where their water comes from i just know the water bill comes. we don't understand the value of water north of the hydro sphere is crucial for the ecosystems that we depend upon and in the magic and that everything is created in the meeting between sun and water. the a 3 in. sort of the solar energy cleanse a sea water and produces fresh water. that's kept nature
6:22 am
is constantly cleansing water in the water cycle it's the rainwater is claim but unfortunately chemicals can be dissolved into it in the atmosphere. that it's out of. the amount of fresh water on the planet depends effectively on and that's the ration and transpiration because she has water evaporates it leaves behind all the salts in the pollutants that maybe in the oceans away from and it just goes up as water pure water but and so it regenerates freshwater. these things. on the sea on
6:23 am
a certain level in temperature water vapor condenses muesli into ice particles or snowflakes the form klutz. 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 it's been discovered that aerosols are needed. small ice and salt crystals which are the starting point for condensation. $1000000.00 of these cloud micro droplets need to be coalesced into each rain drop for it to be heavy enough and large enough to fall out of the under gravity and back to the lead. and so this new creation of these water droplets
6:24 am
it's a cane balancing process in nature. in driving rain. but there are other aerosols that are important for creating raindrops. bacteria. through the about peroration of trees specific bacteria end up in the atmosphere where they bind water vapor 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 that either goes into the oceans or it goes onto the land if it goes on to 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 and. if it
6:25 am
falls a snow then the beauty of that is that it stays. as a mountain reservoir of water and it doesn't move out of its system very quickly. so there's just this constant exchange of water moving across the surface under the surface into the atmosphere and then back down to the surface. when the rain falls down there becomes ground water and it goes slowly deeper than that it takes up minerals here and bravo we have ground water at about 18 major deep and about 200 meters deep it's coming from belgium and
6:26 am
it travels with the speed of about 20 meters per year since very slowly and it took about 10000 years 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 page may vary but most ground water reservoirs are ancient and were created long before humanity appeared on earth. and it's formed by rainfall that dissolves minerals and nutrients. it's the best in purest of all water and the most important water resource for us and the ecosystems. if you pump groundwater and in every year you're using that ground water without it
6:27 am
being replenished then the groundwater is going to decrease how far can a counterfeit how much water we pump air flow $2000000000.00 with a b. gallons a year. i spend more than a $1000000.00 every year on electricity to pump water through it's the land of the big acreage is. from farmland grows animal feed such as corn and grain on 14000 hectares. these cultivations are possible thanks to one of the world's largest systems of fossil groundwater being available every ogallala aquifer supplies 8 states and about 2 and a half 1000000 inhabitants with water. but the levels are dropping.
6:28 am
unfortunately we've pumped in this area at least 30 percent of the awkward for say dryer we feel we have lowered it and as we do that the well is more pressed to give up the water and there's a lot of wells that are only half of what they did when they were 1st developed. the debt off the counter they get fair might be enough water for 50 to 70 years. and then it will be gone groundwater is being overused all over the world into. large scale operation and monoculture cost water. it's not only the farms in kansas that consume. about 70 percent of the planet's freshwater goes to cultivation and food production. to the large scale model cultures drain the groundwater systems to dangerously low levels.
6:29 am
of the ogallala aquifer ever be drained it is being drained right now i've heard people use the word mind because it's something that's taken out of this ground and not put back as if we were mining gold or pumping oil so mining operation. thousands of years were required to create these ground water supply and so pumping those out of there. in order to get back to the same awkward for level that we had before we started pumping them. and it's going to take a long time. and so this creates a numerous problems in the next couple decades to see agriculture that depends on them is designed to collapse.
6:30 am
we extract more than what is replenished. we're draining the world's most important water resources. but there is another very important water existing in environments that we hardly think of. the soil water. the hidden resource found in the soil which is essential for life in the biosphere. the u.s. soil which cover you know that 29 percent to 13000000000 take these are blends that as i really i spot on each and depending on the quality of that sponge they can hold up to 50 percent of the volume in water a. significant amount of water is actually stored within the sponge and as a ground water and as a matter for me it is more than the water that we just see the formal free verse
6:31 am
and like. in order for soil and cultivated land to function and supply water it must be healthy and alive. microorganisms in organic matter preserve water. in a time when rainfall is unpredictable this is extremely important for. the critical thing is what happens to every rain drop that falls on this earth because does it in for trades and get retained in a form and location where it's a valuable for plant growth or does it run off the road. systems and then get lost into the ocean and the difference whether it infiltrates or runs off depends on the soil caverns sponged whether that spans can have the perasso
6:32 am
city in the permian believe me to absorb that water and then feed it into the deepest sort of risings. in so reservoirs because it's that water that you haven't . life in the baathist. industry of formal farming before the ability of soil to hold water. it just loses me almost and you know very complex soil on top of that which is there i let's say you have a heavy rain or any form of frisbee station just sleeps on the surface because the soil will become cater for the fall the soil spine is leaving us and groundwater in charge he's leaving us because of that so we're just flushing the vital component of fly away from ourselves.
6:33 am
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 are been eyes the planet through industrial development and the soil horizon that was an important water reservoir is being sealed under concrete and infrastructure. if they haven't i think said so forward your cities are growing and we're asking the planet yet are you gonna be tarmac the farmland that we isolate farmland from
6:34 am
the water cycle to be able to be cut off greenish diverts surface water into reverse and leaks. and is often quite polluted. water from heavy rainfall has nowhere to go toward life or more got off the hook for that run straight into the sea. isn't pretty use. to me i mean it doesn't replenish the groundwater of a few or it's not a resource or go on and to go. to sea drink or to really decrease do with long we decrease the bill you do a city would decrease the water situation soup we decrease the want to cycle. we consume groundwater and create hydrophobic soils. we isolate the soil under harden plans and the precipitation is diverted. this means less water on the continents and declining groundwater systems and the consequences of this are
6:35 am
extensive. d.-r. duration is a long term process also less and less washoe reaching the groundwater that makes that for instance tweens and all our plants can't reach the groundwater anymore. and the impact through the desert surely quite horrific because adventure we call ourself 1st base for all the warm water you know we mean if coke's before you realize is there the water is so hot that it's going to die. there are a baby with washing away less water is coming in and he says how did the certification come here slowly but.
6:36 am
different regions are experiencing already significant river cation losing 20 to 30 percent of their rainfall and risk turning more and more into days. when nature withers from thirst it gets warmer. more solar energy and neither water nor digitization can help the cooling at the source. power consumption and use of water resources have a direct impact on global temperature and our climate. it is water that in the sense governs 95 percent of the heat dynamics of the blue planet and for the last 4000000000 years it is water that is actually regulated the climate. it's the different water processes that govern those dynamics. of being
6:37 am
a 2nd or forced me 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 pisk. or if the a creating increases all we use more was here we increase transpiration in the. door come out than have transferred home. up to now we've been so focused exclusively almost on the c o 2 concentrations the atmosphere that has obviously gone up abnormally now we have assumed the c o 2 rise because it is a green as. yes it's cause the planet to heat up and certainly that is a key contributing factor but a 55 big effect or has been the changes we've been making for years hydrology.
6:38 am
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 model cultivation 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 under that landscape rarely get above 20 degrees centigrade even in tropical regions. converse lee where we have been exposed soil subject to the incident solar radiation space she's sold it hasn't got water that soil or as foetal concrete well that surface can often heat up to 60 degrees centigrade old.
6:39 am
which means a profoundly more info rich he just resigned you hated from hot surfaces compared to cold since. he monocultures an industry all. farming to bring along these phenomena of heat islands because from one day to another a large area is harvested and from one day to another he just switched on in a snap of a finger and you klar power plant that is there anything upwards to seize hold the i recall term and industry a form of a culture which forms the weather. and. a warm atmosphere can contain more water than a cold one and we can safely assume that hurricanes and in suing severe rainfall will become more frequent. in order and they will intensify.
6:40 am
the intensity of them cold enough there. we water the atmosphere with fresh water. 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 the hurricane these stones floods very difficult droughts wildfires and it's these
6:41 am
hydrological extremes that kill human beings. so that for backup what climatic effect on the water leads to disastrous floods and droughts capital for the long term effects can change the conditions for a large number of societies on earth that we have not. yet as the one you could these extremes be the norm in 15 years how are we going to handle them you know the. extreme will become the norm don't 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 ok
6:42 am
when. we get droughts and we get wet periods and it's and it's minor but if it comes 456 years of intense drought or as in the colorado river basin now we're in 18 years of drought we have 40000000 people in the state of california that are very strongly dependent on that water resource. where are they going to go if it goes to dry people don't survive those they have to. civilizations don't survive the.
6:43 am
lack of fresh water is a reality many parts of the world but that's 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. some of the suited all so he had a lot of goods are imported from regions where there is a shortage of water with. a lot of water flows from arid areas to areas where water resources are already plentiful so should. so have them the funds. tend to think of was as a local call so that trading goods means we have an impact on each other. in
6:44 am
everything. from bottom feeder team. everything contains water from textiles to cut flowers. our lifestyles are costly and we exhaust water stressed nations access and right to safe clean water. it's not only about products half of the food we consume is imported. now it's time for the 40 percent or 30 to 40 percent of all food stuffs are never consumed the nuclear ruined by poor storage or poor handling or just thrown away. if there are the equivalent to the us production of foodstuffs is just thrown away . and that means we're also wasting water on the you've got them that's that.
6:45 am
we consume large volumes of water through overproduction and discarded food. things that don't just waste resources but also generate pollution. you. know what surely affects our behavior because sooner or later after we faint we do use all. half and up and watch. the chemical footprints that we're finding in reverse and blake is definitely a reflection of the whole show and society in trucks with little interest when we're taking some boats near a city it's more dominated by ditto gyms and cultural small don't buy because suicides if you take it near a mining area you haven't chosen much of this in the us so we can truly see the human activities all driving the chemical footprint in the river.
6:46 am
of the agricultural use of water here in our state of kansas the majority would be for watering crops and one of the concerns as water filters through the soil and makes it all the way down to where they are for is water quality and the one big concern we have is leeching of nitrogen fertilizer. in this country we have a lot of livestock so we have a good mood of the problem with far too much when you are and we see that in our groundwater and also in the water in the kitchens and in the kennels. so i think an arbitration and bound would result show a problem fall by the 1st chain saw and. the nitrogen leeches down into the awful for which contaminates are for drinking it it isn't just irrigation water they can do that one of the big sources is the runoff from feedlots kansas is the largest meat packing state in the united states and there are areas around feedlots where
6:47 am
the drinking water is too contaminated to. it's 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. rocksmith than this but all those things for me and those here is an excellent solvent it absolves pollution so that it becomes part of the cycle. of there are all sorts of pollutants in different parts of the water system. so cleaning it up is energy and cost intensive. the question is how much of it can
6:48 am
we cleanse ounce come. you know you'll see it used for the pollutions are a big problem. there are many unrecorded issues we don't carry out tests everywhere in the city. we dilute the chemicals in the belief that the consequences will be smaller. but despite our efforts to minimize risks that effects of our usage of chemicals are extensive and already noticeable. the drugs that are in the service what are painkillers but pressure medicines diabetes left to cause all sorts of medicines we use daily antibiotics and while they have also different effects on the ecosystems in the water. our naive relationship to
6:49 am
chemicals and chemically manufactured products is unsustainable this makes large volumes of the available water on earth useless. and in addition we have plastic. trusting that it's often at the fence there are plastics in tap water and there are plastics even more often in bottled water give us we're drinking plastics provided each day per square metre indoors more than $300.00 plastic micro particles collect to leave a glass of water on the table and you'll be exposed to them with yes they're in the air water and food and it's experience the impact on humans has yet to be studied that is we're starting to understand the impact on animals and organisms but we don't yet know the full effects. yet men to be hoarding in but awesome lots of water pour ific then. plastic is everywhere and in
6:50 am
places where people often meet artificial turf small plastic fragments and granules make their way down the sewage systems. there's also the possibility that micro particles 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 bloodstream a strain. and surely this reflects on a says humans and our short intense time on earth.
6:51 am
over the last 200 years that's the period that humans have really come to have an enormous influence on the earth system and industrialization itself is not all bad it's just how we capture what we're doing and understand how are influencing ourselves influencing our ecosystem influencing our water supply. biodiversity is like a pyramid at the top of the feeder i mean this is a place for human beings and if by you do as his does a spear human being this is pure too so it's very important to protect the bio diversity. and also there is a big connection with water clearly or decided to play a role or order good order true but also for the good lord in the future mission i didn't mark. and this area is so so important too to read you good to go by warming
6:52 am
so where in peoria and this kind of my writes about to get your cups you're 10 times more suited to being of gas than as a story it's very important to preserve this place to get you and to read you the bar room. we have to take cabin out of the air was basically put there for mad the good asian development and put that back into our soils to rebuild the sponge so we can rebuild. hydrology. 2 to 3 percent carbon added into the soil. can create these structural regeneration effects. add voids. into that sort of matrix and really reboot the system. through photosynthesis carbon can be bound in the soil but in nature transform
6:53 am
carbon dioxide into a rich soil with microorganisms 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 one defocus into this turns on you will see a significant drop in terms of the amount of carbon dioxide and get us here which goes down as defaulting to progresses through the summer and then when we had before and everything is harvested again you will see a significant increase in terms of the concentration of the carbon dioxide from the shoal the magni off impacted before posting to as s. on the amount of carbon dioxide to go up also here. soils are also fundamental because it's the only point of agency the only point of influence we humans have
6:54 am
on the it is climate hydrology and our future you see we can change the oceans gondry change the ice caps we can't really change the atmosphere we can to some extent but the real point of the agency is a sponge. there is clearly an over consumption of the water resources on the planet for consumption that affects 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.
6:55 am
we are not using the systems that nature provides is the lesson that nature provides us and once think we are bad night and we have lived the last century with delusions that we can fix things technologically good think the reality is coming that they are limits there is an imperative for regeneration and hopefully we will have the wisdom to now say hey this is work with nature it is get out of office roads and live a braise and live her hope to actually be generous these gods just. we should be more aware of the fact that our brown water is a treasure and use it with. respect as you treat a treasure some miracle. somehow it's a miracle that we are so used to me count see the miracle in.
6:56 am
some of the most ill and what society has to do now is monitor how we use our water resources. the source so that we avoid overheats and too much pollution of which would ruin the basis of our existence then for would be again existence. so we really have it in our hands now. to understand how these water supplies are changing these water forces as well as the interaction with the climate are changing so that we can sustain. the standard of living and. and. and the health of. the human population.
6:57 am
we are one. of us the water and nature. we need to rethink to stop polluting and draining and instead retain the water on the continents. because the carbon storage and think of cultivation methods that replenish the water in the soil in the ecosystems and in the ground water. 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 as spongers up in so reza was a i draw logy the cooling of the planet. nature will always be here out of
6:58 am
a nature can and will restore those by assistance the only question is will we hope or do that or less and do it by herself after we are gone. van. for europe's to have the market. in the middle east lessons have been taking place in that holman for several weeks now because the internet is drastic measures and exceptionally challenging times for teachers and students. become much when students learn during this time of the program. it's focused on the.
6:59 am
7:00 am
this is d.w. news life from the end of the world wide death toll from the corona virus was passed. 1000 and america's most populous state issued a stay at home order. just a moment we need to make tough decisions this is a moment where we need some straight talk and we need to tell people the truth. the order comes as the united states warns against all overseas travel. and the
