The la shadow of the 1970 to olympic massacre. Stuart september, 3rd on d. W. Ah. Nature depends on water. Without it, nature can no longer exist. The field horton, i owe much drought, can our ecosystem waters withstand base . If the Climate Change is over a relatively short time, whats inside, im and 14 is near. Im please. When it comes to Climate Change, we are only now just beginning to feel the effects youre ecosystems are already collapsing globally dark. Now we also have to worry about the worst of all possible endings, like dickie ended up with such a about 80 percent of the trace died and nothing can be done. Here we have a 300 percent over use of water. Im literally sitting on what was a boat ramp driving such an impact that we could kill the Colorado River side. Ill find it difficult. I can. No one can be without Drinking Water from with well certainly head it for a grave. Hodge, a logical catastrophe. Esteem lemons. We can say that a violent confrontation with nature awaits us with dental to them. We are used to an abundance of water, but that perception is changing quickly. Thanks to Climate Change. Ah, less water is leading to frequent water shortages. This series raises the question, what happens when the wells run dry . The town of mountains provide most of the Drinking Water in germanys vine mine region. Asked clarissa, as the former had of these buttons, water, authority, and ecologist, andrea asunder man, has studied the impact of extracting water from the town as mountains on the local nature, all over germany. The consequences of the drought are visible. As you can see, im walking troy floated through or used to be a street or carried water whole year round. That estate had cyclists, unusual. Standing on this with the ledge and euclid in lubbock gravel under fees. Eli carson mm doesnt at all. Its sad to see the stream like this it does, it just confirms we have known for a long time because i did the water extraction, interferes with the ecology with groundwater levels and also drains the landscape public. So why are rivers and streams drying up . We look for clues in a particularly hard hit region, water rich bavaria ziemen pies from the northern burg Water Management office searches for a pond that is a tributary to the peg nates river as little as you can so forced ends walk, you have to imagine that only a few years ago, this was all underwater watha. Our dissect what theres nothing here. Where did the water come from . And where did it go . The 2 experts are looking for the remnants of a spring. If i few of you can see that the water level used to reach above this plot or loss, ashton can. All right, incredibly, this is the also that not to of need our flock. Relative nature reacts relatively quickly to rainfall, immune gas, just like when youre water, your flowers and a yeah. Yeah, it will be sent to avi about what were talking about here. Thats how it looks underneath the surface via even through our official Monitoring System so that we can see that in recent years and let the levels have not recovered during the winter like they used to. But in v in tie in that, and thats a big concern, nick, or was his organ the, the arm through a series of us that ill skill often have the receive water used to flow from here and fill this context. Now the water table thats in the mountain behind us is even below they said, you see where the water used to gush out and what is also for the asking fitness. The debit. I woods. This area where the water used to flow through is completely dry. As you can see, i cannot, i have some images from earlier this year where you can still see some water here. Now its basically just a dried out cave. No animals could talk me to hulu, as is not needed. So on. The situation has never been as critical as in the last year seal and because of the consecutive dry, somers and springs with her eddie, the alley tom. Where does our ground water come from . At the Potsdam Institute for Climate Impact research fed hunterman analyzed as the german weather service, his records of precipitation and evaporation. How is the available water . The water supply changing . Is a quote, the door that this corridor between precipitation and evaporation sometimes is what les to becomes ground water and flows into the rivers. Does dust thus, not the water we can manage it. But as these are corridor, but we are seeing this corridor getting marrow submitted in yet the annual average of rainfall may remain unchanged if we have less water. If its sort of in top thus because our winters are getting sure. Still does this members warmer weather means more of operation as who and causing vegetation to grow for longer periods if it is an offer and winter is when the water tables and reservoirs replenished the from the phase where we dont have green vegetation. When does a phosphate, however, that phase is getting shorter of excess, meaning that the same amount of rain eventually leads to less water for humans and night. Josh, on the 20 not were over the past 50 years, global animal populations have declined by an average of 68 percent. And even though humans only make up 0. 01 percent of earths bio mass, we are responsible for almost all the negative impacts on everything else. The zinc and beg institute in frankfort on mine has been researching biodiversity since 1817. What is the correlation between biodiversity and a dryer climate . The sphere tank on finance was to bunch to do what weve been able to show in our global study for us is that streams and rivers drying up at the surface have become the rule. Not the exception safety plus the 60 percent of all streams and rivers naturally go dry. Have i said, but when a stream that permanently carries water begins to dry up and there are obviously massive consequences again, oh, super both for the environment and for the availability of the quality of the water for us humans, im not as i certainly healthy for food but i can city quantity dispatch suspense, mention the consequences are becoming apparent in germanys, im mine region, a large part of the Drinking Water for the 5800000 People Living here comes from the town as mountains for more than a century. Millions of cubic meters of water have been pumped out of the ground every year. How does this plant operated by hassan vasa . One of the largest water suppliers in the region affect nature and st. Clair is the former head of the Water Authority in vs button, one of the largest Population Centers in the region. For years, claudia has documented the consequences of extracting Drinking Water on nature. Hinder, mia is im good vis or am the slots blocks or the hind me is an arm of the schwartzbar river that has gone dry scans a yard its dry throughout the year due to the water extraction that is located here above us, extra large months per extra for the next door, i think the consequences for nature serious the it is cotton progressively worse because of the drought in the last few years or not so can dominate. This is not so hot it north air for shaft. One of has in vos as customers, is the city of older ursula, near frankfort. Over ursula public utility supplies residents with Drinking Water, managing director, eula and tony and technical manager detect reddish, explain where the water comes from. Its given us cookie dom hawk totals come on for something about it to the extraction area in the town, as mountains, as a boston alysia dot com were extracting was a furnace passed up town was that the town was also an owl club. Thats the old back river to doctors, and the flow of the little box has to be at a certain level. I mean, for us to be able to use our water. Right. And the town us import us proposed amount of the whistle, bath river flows through the entire region and Drinking Water cant be taken out unless the awesome buff is carrying water. Andrea andermann from the thinkin Berg Institute has been observing the river for years. Eyes of isnt he understand from was about him so much that hes talking fed monkey standing at the pointed to it was about if it actually dries out during this m m m. Austins almost easier to imagine if you look at some pictures and that is in from, by a spirit. If that is, for example, is the few downstream him. And you can see that this channel, this gravel bed, is completely drying and once doth amounts because Drinking Water is being extracted from the upper reaches of the ocean. Batter back rougher and water that is extracted. There is what is missing loss and non via the fear it is all stella water for citizens or water for the river. Its a tough choice. And what are the consequences for the entire hind mine region, which gets much of its Drinking Water from the town us. Competition for water as a resource has already become a fact. And here in the heart of germany, the demand for human Drinking Water is competing directly with natures needs. Not only as plant life affected aquatic life is hurting to thus hot, ill always, melissa has an impact on the value of diversity. We are knocking certain species normally found here because they cant cope with it, which used to play with water them. And so i p here and for citizens within men are streams and rivers are among the most bio diverse habitats in the world. It cause im easily comparable to coral reason or tropical rain, florida certified only this diversity is under water. Them not immediately visible on the lands on them on is doing field work by the elizabeth river. Shes collecting samples at several locations to document the current biodiversity and for closer examination in the laboratory in dutch unseen through a seam puts in a leper hewn frisson in germany, closure only 70 percent of all streams and rivers. Whats are considered to be in good ecological condition, occlusions which means that 93 percent of water body assia are in poor condition. Im increasing the hub and this will be despite the european washer framework, director of beasts weighed thousands. The directors goal is to achieve good ecological status for all water bodies by 2027 as seen quickly. And we are now it just a 70 percent on moody. That means that its impossible to achieve this target oconnor, which i think the question care must be. Why to be formulate target a c live that we know from the outset or out of reach. And this with our current effort to see a misuse, an unsettling on t. V at the outset on the name and he said, see, late kindness, fuss as i have. What will thunder men find in todays samples . So to males, i shouldnt be more met one wedding, not necessarily more individuals with much more spc feeler. And for all, there are several types of nationalized contest lies, and beetles missing egan is still in that sense. We really have a rigidity, synopsis diversity here. Hot and few normally, there are many, many mosby funds on the body of water like this often is on the vessel. What are the consequences of such reduced species . Diversity for nature, the hook go that below his feel for the decline of biodiversity. One is the biggest challenge we face as humanity. On the one hand insights, one, something is lost and one, its lost forever one. And on the other hand its, we dont know what a 1020 answer or the 50 percent decline in this diversity. This of will mean for nature and ultimately through for us in the long run, long for a sticker thought. But human impact on our waters is not limited to just extracting Drinking Water. Ya does also have in the stair also what we are seeing here, mr. Ronald from the over little Waste Water Treatment Plant up vasa, its actually purified, waste water. Hes actually on logan downstream. This long we have a relatively high, isnt he just purified, waste water in the river when you so we have a very low jesus, no species composition. Not only after you still see that can cause humid deezen, but these are the towards the ones like com. Purified water sounds harmless, but it contains toxic residues from micro plastics to pharmaceuticals and pesticides discharged into our streams and rivers. Scientists and hanover, the cap of lower saxony are currently investigating the impact on ground water pool. This is warehouse hylas team comes in. Hanovers Environmental Agency has been taking a hard look at groundwater over a long period of time. When that link vasa v at yahoo are Drinking Water is mainly fed by ground water off times. Any adverse effect on the ground water will eventually also affect our Drinking Water. Buffalo, new national. The researchers 1st collect a water sample. They use fishing line to lower the receptacle 20 meters into the monitoring point, and then fill it up with ground water. Storage of the thrust of his machine from the water will be chemically analyzed and his capture to listen to you. You little bit lower it down to the bottom of this grown water, should alpha so low its almost all know that weve collected the washer. We can begin the chemical examination. The ground water will 1st be screened for residues in the laboratory. And then experts will look for living organisms. The vision shaft vickers, we have recently been using more scientific methods only a few more, which allows us to look for different kinds of micro organisms him. If they were to find species that would normally only be found on the surface, it would be evidence of surface water mixing with ground water with the underwater camera sinks deeper and deeper into the ground Water Monitoring point, looking for micro organisms. But a more detailed examination is necessary to the water samples from hanover. I have been sent to the university of Copeland Landau for analysis water ecologist, hands yoga and hahn and his team will take a microscopic look at the samples. Ah, this one is quite interesting. Were the scientists suspicion is confirmed when a small, almost transparent creature appears under the lens, is, will look up as any man concerning him, vice doth. The secret, sir . Always an indication of surface water infiltration that is in this sample also contains freshwater copper pods, which a typical organisms found on the surface. Leslie hill, if you find those in samples from groundwater or Drinking Water reservoir think, but you notice something is coming in from above past liquid levy. The most of all mine. But are these findings really cause for concern yet . And if so, why . Of a lot of that is seeping out as neither Drinking Water nor fresh water from the springs us on to a great extent its waste water from treatment plants. It puts it in the rhine river. It is about 50 percent 80 percent in the neck. A river and sometimes close to a 100 percent in smaller streams of buffer waste water flowing in streams and seeping into groundwater, obviously poses a risk to quality testing the chemical composition of the water samples from hanover led to some equally disturbing findings that didnt oversee min erm infiltration bon wanted substances can also be found in the locations in hanover affected or influenced by surface water pharmaceuticals. For example, to buy so far the concentration is very low in there, but detectable nevertheless on although its the dish i wanna respond. Vic in different areas that we are assuming this will get worse in the coming years and decades for 2nd read an american study from earlier this year when i showed that a considerable part of the waters, the especially in the west, had been contaminated infinitely. There are many pollutants and, and the situation is most critical in areas where surface irrigation is used for agriculture. Duction are renowned. Hydrologist is claims. The impact on america, the west coast. Im j family at a. Im the executive director of the Global Institute for what a security at the university of saskatchewan. Im a hydrologist. I havent been down there in a while and to see how things have changed. How things have dried out. Since, since i left california in 2018, really incredible from nowhere is the impact of wastewater on nature, more evident than in the imperial irrigation district. One of the largest agricultural areas in north america, its man made. And in the middle of a desert, you really need to get out at these agricultural regions to really understand their vast expense. Thats true in the central valley. Its true in its true in the imperial irrigation district, you get out there and these fields just stretch and stretch and stretch for miles and miles. And thats when you realize just how much water is being spread over the surface to green up the desert. The imperial irrigation district spreads 3. 00 trillion leaders of water per year in the region. Meanwhile, 40000000 local people face water shortages and nature is drying up. The runoff from all the agricultural fields gets channelled into rivers and is delivered to the south and see which is internally draining. Which means thats it. Its like the dead sea. The run off that goes into is full of fertilizer and pesticides, so the water itself is toxic. I dont actually know if it can be saved. I dont know what it would take to save it. The salton sea is the largest fresh water lake in california. It used to be a vacation resort to day, very little can live here anymore. Yeah, im literally sitting on what was a boat where the lake is seeping away and evaluating the salton sea has been been a tragedy. As the waters have receded. Its created dust that blows into as far as, as the city of los angeles, creating air quality issues to begin with. And then there is the increased solidity of the water. So youve got a, a number of, of tragic issues that have arisen where there were once parks and recreation facilities there noun, baron beach lands at best. I remember when i 1st came to the salt and see a few years ago, the water levels were literally thousands of feet closer than they are today. And it just is a startling thing to see me. Humans have consumed the water for farming in the desert, while poisoning the water, that nature needs to survive. In the long run, the consequence of this dying nature will be a loss of human habitat timescales, at which were talking about here. T
