but a few rough you are connected to the world ah, experience our standing shopping and dining offers, enjoying our services. be our guest at frankfurt airport city, managed by from board. oh, i the this is d w. news and these are on top stories. italy has been crowned european champions at wembley stadium after beating england on penalties. italian fans rejoiced after a nail biting finish, which saw england missing 3 of their 5 shots. it's only the 2nd time if we have lifted the european championship trophy the 1st time they picked up, the price was $960.00 i me thousands and cubans and take it to the streets and the country's largest anti government protest in decades,

caribbean on and people are enduring, rising prices, shortages of food and medicine and record cove. it infection numbers he was president, has called on his support, has to mobilize to suppress the demonstration. me, british believe that richard branson has completed a maiden flight to the edge of space. france and 5 other crew might spend 60 minutes on board. the virgin galactic space plane soaring 80 kilometers above the surface, mission control says all went as planned. the fine aims to usher in a new era of private commercial space travel just like this for a minute before they w news from berlin. there's much more on our website. that's d w dot com ah, the

welcome global 3000 in northern canyon. a tenacious woman takes us termed the peace and women's right vietnam's prosperity. so does it been trust that chaos is the way to put the brakes on the test. the world is getting hotter because some people feeling the effect more than others. the me climate, justice, the time it justice now was that we're hearing more and more the climate justice linked to racial justice, social justice and intergenerational justice. these why we call not only for climate action, but climate just the most that good shape this century. exactly. does climate

change have to do with justice? all we all together. evidently know it in a forest fire, only some homes will be back to the ground. a mudslide, white thought one village at least and not the run. it's not just me. oh, are we asking the wrong questions in to understand climate justice, we need to understand climate injustice to cause of climate change and who's hurt by it? that 1st look at who's responsible for putting carbon dioxide into the atmosphere and heating the planet. imagine this grain of rice is one kind of carbon dioxide each year. the average passing in nigeria is less than one grain into the atmosphere that's in india, 2 grand and china, 7 grains, jeremy 10 grains in the us. 17 green. and one year, the average american troops 20 times more than the average nigeria. but the problem

with carbon is that it stays trapped in the atmosphere for centuries. so it's not just about how much we added here. it's about how much was piled up at the time since $850.00. that's up to about 1500 giga time. okay, so we want to follow that these rice bags on the table to show you how big that really is. but after doing the math, we realize we need 3000000 of them. historical emissions matter today because countries are arguing about how soon they have to cut the met emissions down to their big polluters like china, india, and brazil. look a lot less guilty when you consider that you recently become part of the problem i and in phase 2 caught the annual emissions, but that doesn't tell us anything about, you know, why or why we are in the current in 2020 recently,

to help countries responsible for pushing here to levels beyond the safety threshold that we crossed at 990. the study takes into account how many people live in the country, how much they emitted throughout history, and include the missions across the board of trade goods. the research shows that countries have out spent that carbon budgets buy a lot to global north of emitted 92 percent this year to push the planet be unsafe level asia, africa, the middle east and latin america have emitted just 8 percent. even a mass of a middle china is only just using it's carbon budget now. but if you live in a country that runs on top of the list, does that mean climate change is your fault personally? but some of your choices do still make a difference. because it's not just about where you live, but also how much you spend the weather, it just one percentage. it's twice as much of the course, 50 percent, and delete live all over the world. the unequal emissions. one big reason why climate activists shouting about justice. everyone already is

effected by the fact that price is just very different. but if we look at the people ruling germany and sitting at the decision table for the past decade, they have not responsibility for vitamin. i do now not live seem to heat the planet by the same amount, whether it comes from germany or kenya. the climate doesn't care about geography. well, geography cares about the climate. the 2nd part of climate injustice is that even the poor countries have done the least to change the climate. they're the ones getting hurt, the take heat waves and drops heat waves the becoming most, some variable across africa where drought, the even more punishing for crow. ah. then the storms

warmer. i mean, the hurricanes and typhoons carry more energy and unleash more rain and stronger winds across the tropics. and by 2050 sea levels will have risen so high. the floods which used to hit once a century was tricked many coastal cities every single year. the inequality, the climate change come to the hottest in a country like india, even though people have barely contributed to global warming. there among the most vulnerable india. coastal cities are facing unprecedented floods while it's rivers dry. up live in pharma, struggling to grow staples lake rights and weak the india either one of the most equitable countries in the world. and what we can see is that even if you take a city like when flood happened in the city, it's the poor that the most impacted. this says pile correct. a climate scientist who campaigns full time for climate justice. having grown up in

a country like india, i grew up with inequality all around me. and this is essentially what it comes down to. the world is very unequal and it's playing out in terms of climate change as well. but that inequality is found within rich countries to black and brown. people in countries like the u. s. for the u. k. a typically part white people. and that mean they have less money to spend on air conditioning to adapt to heat waves or flood insurance to rebuild up the storm. ah, how can we make it fair? well, police country confessed here to start removing that pollution from the atmosphere . then they could pay reparations using more than their fair share of the mission. ah, some countries and company know ready doing something similar by paying for countries to not drop down parts and instead countries but instead of using that saved carbon to attend to the climate day, they're using it as an excuse to keep on emitted. ah no primary reason

to be part of that discussion and time is that in particular is where we think about who is you know, we kind of divide up who is responsible for the kinds of changes and climate change with being an enterprise and but also the kinds of climate induce disaster that tells me reparations might sound radical, but rich countries already agreed to pay poor ones to adapt to climate change. imagine each of the piece, $1000000000.00 us dollars, rich countries promised a 100 of them. epm climate finance by 2020. but it's 2021 and they haven't popped up in 2018. they did 80000000000, but most of it was learned not granted. you can't based charity. sam found that the real aid was actually closer to 20000000000 yearly. we have not been meeting the kinds of part it did even global,

not countries set them. so that finance mechanism not meant back to solve the problem. another approach takes climate justice more literally holding polluters to account in court to deadly whilst i've taught reports in 201760 activists took 33 industrial countries to the european court of human rights. failing to cut their mission quickly, they argue that the countries are discriminating against young people who have to live with the consequences of climate change. the vatike to still pending, ah, in germany, in the middle and high court judges have ordered the government to up them. missions on cutting emission activists also want a case against royal dutch shell, forcing the company to pay for oil pollution and now demanding climate friendly investments to ah, so the, the basic legal argument for assigning responsibility is you know,

contribution to the problem. so how much do you emit? how much do you contribute to climate change, greenhouse gas emissions. and what is the possibility for contributing to the solution? the defendant talking about national courts don't have the right to roll on the climate because emissions and the impacts are global. but a new generation of activists are fighting for them to take exactly that responsibility and give them climate justice nearly 1400000000 cars in the world today. and by 2015, that numbers predicted to double in 2020 alone, 78000000 new cars rolled off the well to assembly lines. more cars means more land for more appellation, more noise and more congestion. and big city drive is already spent untold hours and traffic jams and all unseen series. we have to vietnam,

where the traffic has become truly monstrous. and it's not just the drivers who are suffering from the feeling of impatience is constant attention from the in on it affects my state of mind and my mood last the also frustrating and annoying. ah, it's an issue that just the local authorities major, heading off on not just the oda. sometimes the color of the noise

of the traffic jam monster is really annoying when it's dark black and makes unpleasant sound flow. it has ice and it looks scary. so the i bought a car in late 2013 and then i felt freedom and comfort. i felt happy. it's hard to find that feeling again

the number it out. it's all, it's true that for most vietnamese people, a car is a symbol of success while being heal. but after you've been driving for a while, the car becomes more of a tool and less of an asset guy at the time when you're somewhere

i'm and i'm a while. and in the building my personal observations with the data we've collected show that in the past 20 years of dealing with the traffic related problems in viet nam have been getting worse and worse. why no noise developing so quickly punching? why now? it's like a powerful magnet. why my challenge for major cities in vietnam right now is the transition from motor bikes to cause. and that will continue in the near future. in my victim, the mars occupy more of the road,

but they don't carry many people. and then, but now the job vietnamese people are very lazy when it comes to walking, the maximum distance we're willing to walk is about 300 meters mathematical in one name. i don't go if we want to promote public transport on and we need to pay attention to planning and design to make it easier for people to access it and why they're really nice people, especially in cities, are used to writing motorbike so even when their homes are very close to their offices, are schools alone? me turn in and i need to coordinate with schools to encourage children to rule out how to listen activities on

a regular basis. and children and parents can change that happening. don't look a little more. look at me. i don't know how i would have learned that when you cross the street you, you have to stay on the pedestrian crossing the law. and when you cross the street, you have to pay attention to the cars and cross at the right time. if i need to do the math up, my phrase in my colleagues often ask me when i'm going to buy a car. but it was, that would be my goal is to write a bicycle as much as possible. me for walking. well,

currently the sidewalks in vietnam art for pedestrians. that does it all. i know i just did my schedule and my committee to avoid rush hours with my choice and a lot of other people probably do that to you. but i the doctor, we have to keep promoting public transport and provide adequate and affordable accessibility with consistent quality. because everyone uses it, even wealthy people are willing to the mindset that we need to change and we need to learn to share with each other to the

last year that were more than 70 conflicts in sub saharan africa. most with island, some lead to open warfare. the reasons for our complex fighting often revolts around political power, land and resources. these conflicts will only grow worse with climate change as water and usable lungs grow ever more gas. of always conflicts requires cooperation between opposing parties. but keeping the peace can take grit and determination. the bush here in northern kenya has become almost a desert. the a one year old river reduced to little more than a trickle for years now. the area has had far too little rain shepherd up cooler, keeps his goats close to the water. at least there's something for the animals to graze on here. and he never strays far from his village. to la tyrese.

these days we fear for our safety. well, our neighbors, some poor community keep attacking us and to see what they kill and steal our livestock. he's coming to help deescalate the conflicts. habib teacher often reaches out to the shepherds along the river. she used to had the local nature conservancy and is well known in the region. disputes of water and grazing land have become frequent here. she negotiates with the shepherds in this area of the legal police are, while other women are in dialogue with nearby community. we have many meetings, these meetings, especially like local willis. i'm leading lake sarah. that is let me see. think so even though because we mother and we know the disadvantages under

different digits of the conflict. so we decided to sit with our young ones. those who are living in conflict, what hasn't been and that's what makes this unusual. women are taking the lead and making a difference. the canyon constitution upholds gender equality, but in practice, it's still the exception that kenyan branch of the environmental group t n. c is led by more nearer and younger. she says, can you needs more women leaders like you, but they're actually raising their voice is making decisions on how that can someone can be managed, especially for example, there's a conservancy that has to leave the facilities and they get conservation fees. these the issue or file sharing of those proceeds between the operations of the conservancy and percentage goes back to the communities so that it can, you know,

invest in education, health facilities and others. the t n. c runs 39 nature conservancy in kenya. it also finances, the one in hub b, but just community the conservancy is protect nature, offer job prospects and encourage women to play a greater role in society. how be returned each other benefited from the conservancy and is now helping others. i know she and other women in her village have built a culture center. they did a lot of the work themselves. the women rent out the home and the lodges to visitors and local people, which brings in money that's allowed them to set up a savings club. here the women give out loans to each other using income from the culture center subsidies from n g o z. as well as members own savings that might be routed each other leads the club. she's given loans of $250.00 to more than a 100 women,

mostly to finance small business ventures. duddy rover. got a loan from the savings club to invest in an electric motor for her cornmeal. now she can earn more money. like so many year. she's benefited from the nature conservancy. villainy luke? well, i want to see in the beginning the local community here was opposed to the establishment of a conservative rama. but how bieber lobbied for it so that women could benefit. she's very bray initially just one time she was even shot at i thought, but she was intimidated and just carried on with her work. i and i and they were very happy now idea johnny for years on have even doesn't want to talk about the threat. she's received, she'd rather focus on being a role model for the next generation. at the local school, she encourages children to give up,

even when they face opposition was the lucky girl and i don't allow yourself to be left behind and don't be shy all the time. during her time as head of the local nature conservancy, happy but at each secured funding for 2 more classrooms. here today, she's part of the council of elders and has arranged financial help for children from poor families to attend school. those who have prospects for the future she says, are less likely to engage in conflict. education is the same, can our life in a very low the slave because illiteracy, illiteracy, to nixa has been not stop list our standard for one. after getting education, you have a good job of handling some follow this uplifting just under and even additional education to everything is important. if not the vision i myself,

i cannot be a leader of my community. she loves her work, but as often rushed off her feet. she has 3 children and also cares for her sick husband. then she has 2 small shops that she opened with loans from the savings pub . thankfully, her eldest daughter is able to help out how people hopes her daughter will follow in her footsteps. and she certainly seems to have inherited her mother's passion for leadership. she already leads the local youth group. the was not going to that was the 17th this week we talk label, team in indonesia.

my name is gala ra, gender, and robinson. i'm 12 years old and from indonesia the me. my mother is a housewife, and my father is a photographer at a daily news agency. for the off of these media, the indonesian use to be honest, i don't like going to school. i find lessons quite difficult man. so i feel uncomfortable at school in

the benefit of that, when i grow up, i want to be a soccer player. i practice twice a week. but when there's additional training, it can be 3 or 4 times a week to be i wish the world would be safer from disasters in the future. and i wish the world could be more child friendly. but i also hope there'll be no more traffic jams. he's just on like the that so from us this week at global 3000, we'd love to hear your thoughts say right to us at global 3000 b, w dot com. we'll check out our facebook page, d, w global ideas. see you next time the

me the news me out. like you can take german robotics researchers are developing new systems to release stream on the body, neck and shoulders back. how does the ex though skeleton fair when tested tomorrow, today, the films

that touch our hearts made with courage, perseverance and talent. by young filmmakers we met years ago. what are they doing now? against all? barely not a talent. we visited. 16, w. o. y subscribed to d w books, you meet your favorite writer. my only objective when i write is to share it with a fine beautiful w books on youtube. president george w bush invited us to his summer home. we talked about the past and the special relationship to chancellor uncle who is not afraid to make

a decision was not afraid to lead the kind person with a lovely song. and that's the person i got to know needs clues, this interview with george w bush, july 14th at 1530 you t c on the w. ah. what's this b robots doing in the name of science? me and why is this little muscle disliked by fisherman? and research and how can an excess skeleton like heavy lifting all this i'm all coming up. the welcome to tomorrow today your science show on d,

w. i extra skeletons other fields of, of the animal kingdom anthropologist among us, have the heart external skeletons that protect them from the outside world. vertebrates by contrast, have an endo skeleton inside their body joint inspiration from nature recesses have been designing exoskeletons well. yes. they're often used in medical 17 and can also be put to good use to physically demanding the helmet. schmidt, university, and hamburg profess circle. but why not? and his team has spent the past 4 years testing picks a skeleton. these supportive structures relieve the strain on the body when bending or lifting is kind, we don't know of any universal exist skeleton model that supports several different

parts of her body at once. this is instead you have systems like that support individual areas in the team as if they might be the shoulder region like these 1st 3 or they help the band like the others. you see here? oh, some rigid supports made of metal passive models, an active one with an extra note how well suited the various systems off the use for the construction site, for example, is being tested in a special laboratory. doctoral student sure now is putting on a rigid fixer skeleton that she develops herself. it has a mentor that is designed to help assist the arms and back when lifting heavy objects biomechanics research with him. schubert places reflective mark is the pacific points that the cameras will record. the markets reveal the position of

each part of the body during movement. the cameras transfer the motion patterns to the computer. additional skin senses record the activity as collect muscle carries . the signals are also transferred to the computer. sion janet then begins lifting 10 kilogram boxes and moving them from left to right. the conduct this allows us to see how the system wouldn't believe the strain on a construction worker when lifting or moving heavy object to. but will also show us whether it changes the way a person moves. as mentioned, if an excess skeleton changes natural movement classes that could damage to join the time. so what to the measurement show? how did you commission, by measuring the muscle activity, we see a 25 to 30 percent reduction in the weight being carried during dynamic movement.

this means that the package being lifted effectively weighs 2 and a half to 3 kilograms less. and the optical measurements confirm that the skeleton does not impede natural movement sequences success next don't is an oratory that test system for tradespeople. it's a stuff working in partnership with the university equipment is tested in conditions that are as close as possible to real life. this project is all about heating, plumbing, and air conditioning. so the test is being done in a mockup, ball thread, over to that testing a fabric ex, there's gotten designed to support the bank. it's a passive system without noticing the back support works by redistributing the strain through the harness on. the test subject is strapped into an active support system, which is told by

a motor to support the children for join the x. the skeleton has a rigid structure that means extra weight, but once switched on, compressed air is used to operate. actuated, be allowed to harness, to support the shoulder area as needed. but you to, it's important that the harness doesn't hinder natural movement. the system is designed especially the job that involve holding a heavy powered soul above head height for several hours. in the x, we see that the extra skeleton can dramatically reduce the muscular activity needed for this kind of task. were seen, for example, of 50 to 70 percent reduction in the strain on the shoulder muscles as well. so when effect, we only have to do half the work we would normally do to complete the same task. the research is, make sure that the muscles are still doing some of the work as your blank garnished. we don't want the machine to do it all. we want to use the muscles,

so that will remain strong and capable to avoid the strain injuries and musculoskeletal complaints skeletons. the test phase here is almost complete. we've been in the lab, but when we reach the end of the test phase in the laboratory as and because we can simulate any more, we'll go into the workplace. and so we're very close to that because we want to find out what will help our end users most in real life and best in some work environments. skeletons already in breaking the youth. how god is a painter and decorator and uses a passive support system for many jobs. when other horses today i'm filling holes and smoothing the ceiling before painting. that means a lot of overhead work which puts a strain on my shoulders. and our son was, his employer invested in this skeleton. the system doesn't have a motor but uses the bodies of energy when they know it. and if he flows into the

funder on the back, which isn't charged when the res, sunday gets the energy back back in the sensation of a floating. oh me. i think it will buoyant in water. power has been using this system for over a year before the strain on my arms and shoulders back to the test phase. i didn't want to give it back. i was going to the company, her kid out 6 teams of painted with the devices. and they all say it makes a real difference. digitalization is transforming society at a rapid pace. that's why it's vital for young people around the world to become familiar with computing and i t so that one day they can help shape the future.

inheriting his insurance had a young age is key. project stocks a lot of about an invention that's turning computer programming into child play. this oversized be, is a big hit at this preschool. it's not toys, but a hi tech tool designed to prepare children for the digital age and introduce them to basic programming skill classic music. and i enjoy using it. it challenges the kids and promotes logical thinking later on to the how to plan what to do to the end which command to enter into the be bought to program it for korea. and it's really challenging a great toy, who the ordinance of the fun tool was developed and engineered by an educational

research group in switzerland. it includes a roll up game board and the be bought. the board has target fields such as flowers and honey and obstacles to avoid the children give the be bought a series of commands such as turn right or straight ahead. if they get the programming right, they'll see the destination, the the for them, it's challenging, but not too hard. children in this preschool love playing with the be bought. but how effective is it for teaching young children, basic programming skills? professor l smith down from the switch federal institute of technology and study. and that question also on board is pedro, how do magic founder of the educational lab that created begin to understand? how can i to show like how our main motivation is ensuring equal opportunities for

math teaching i t and schools from an early age ensures that all children are given exposure and access. cannot instagram that for lindsey, since we live, it's live to the family. dennis boys who tend to be enrolled and computer classes and to get the 1st computer on your computer course and committed and socially disadvantaged children also tend to miss out to have enough talent around $8000.00 children have already had hands on experience with the be bought playsets, they combine a simple electronic tool, but the board game format over the familiar to young children. but what do experts say? can a digital be teach children how to program? and what exactly are the basics they're learning here? the doctor who are those appeals include putting things in the right sequence of developing optimization strategies and working towards a goal, sometimes incorporating additional factors. that's what we looked at, prove her study confirmed that young children are capable of learning the basics of

computer programming. although the bod, he's not the be all solution. the why had 2 important hypotheses. first, we wanted to find out whether children learn as much playing on their own as they do when given instructions. and that was not the case. the children need guidance. or despite the 2nd hypothesis was that the electronic be bought doesn't always produce better results. some things could be taught better using a regular board game that turned out to be the case. yet we couldn't opt out. you don't necessarily meet digital tools to teach children digital thinking, but be able to have some advantages, like providing feedback in a playful way. plus schools and preschools in switzerland can borrow them for free . so that will be buzzing around this preschool again soon. the now to this week's view question,

the book has run 220000 glaciers. my suffering research study phone. they've been using almost 270000000 tons of ice a year. that mel for to now accounts for about a 5th of the rising level to level the survey was based on half a 1000000 previously i'm use satellite for think about lumber. had a question about the what would happen if all the earth placed is melted? one result, a human driven climate change is the place is around the world melting. in many places where a century ago, there was a thick sheet of ice. now there's only debris, massive areas of reflective surface have been lost. normally the bright surface of the ice reflects the sun's rays back into the atmosphere, but now the earth dissolves more of the sun's energy,

which hates the earth's surface. the heat is then released which causes atmosphere at temperatures to rise, which in turn intensifies the greenhouse effect. this continues relatively soon. they will be nose lacy is left on the planet. scientists say that all of the 400 remaining is on iceland, for example, could disappear within the next 200 years. in 2019 a memorial plot was installed on iceland to commemorate the 1st glazier losses to the climate crisis there. by one estimate, if all the seals on earth melted sea levels would rise by around 66 meters areas of land would become uninhabitable. even a smaller rise in sea level would lead to devastating flooding.

but rising sea levels is just one problem. out of many, most of the world's fresh water supply is stored in light is an estimated 70 percent of it is contained in the antarctic ice sheet is disappear, drinking water would become increasingly scans. global warming continues. climate models showed that within 5000 years, there may be no great left in any way. if the, if i read why do you have a science question, you'd like us to send it in as a video text over them. if we feature it on the show, you'll get a little surprise from us as a thank you. come on just the news. you can find more fascinating stories from the world of science on our website and on twitter the

today's nations list during the last ice age and the constantly shifting. their motion is dependent on the gradient of the slope, the structure of the ice, the temperature, and other factors in the else in europe, there are thousands of places including the mighty rhone, lation. it's a magnet for tourists, eager to explore its ice grotto. and it's also a huge troll for scientists. the researchers on the rone glacier in the swiss alps are investigating a fascinating phenomenon, how glaciers move, and how they slowly but surely slide into valleys below. in other words, the glaciers dynamics, an issue of global importance. the blue biology lavonne says practice it's relevant globally because practically all glaciers,

including their own pleasure slide and the biggest i sheets out large glaciers where the sliding is incredibly important and the way they slide determines whether or not these glaciers move forward, hold back or remain stable of the so we'll see, you know, if we don't understand how glaciers move, we can make predictions for the future. how the glaciers will behave and weather and how the res sea levels are high, made a speech and staying less than the glacier bed is drawn down toward the valley by gravity. a little like flowing honey. when the ice flows over the valley floor, it can run into hurdles such as protruding bedrock. oh, when the stress within the ice becomes too great, it sometimes released in abrupt shocks, much like an earthquake. these ice quakes that occur across the surface can be measured with highly sensitive fiber optic cables. they're an important indicator

of glacial motion. glitzy ologist, fabi on votter has laid one such cable here. didn't cause shown visits, and this cable allows us to the hundreds of meters down the mountain and we can then measure the tremors that come from within the glacier. nikita carbon of measuring the ice quake across the entire breadth of the glacier is critical to understanding its motion. a computer analysis shows all the rumbling going on inside the glacier. doesn't be a real time. it's coming in now record seismic vibrations that we measure in the cable. you can carbon lessons in my than what we're most interested in is the glacier bed. that's the center of the glaciers dynamic. com. did you nami, an glitch when a glacier produces a lot of milk dice and has a very weak bed?

because water is accumulated there, then it can begin to slide like puts at. this sliding process occurs all over the world. enclosures with the bed isn't frozen. that's where the glaciers dynamics come from in dot com to exempt unami get through. the glaciers motion also depends on the water inside the glacier. using this portable radar setup, researchers can detect that water. the dynamics are also influenced by melt water. water on the surface of the glacier, it makes its way inside through cracks and holes. progressive down to the glacier bed, then flows toward the glaciers and or snout. the glacier starts to slide more quickly here because the water acts as a lubricant by reducing friction. alpine glaciers like here at the source of the wrong river flight 200 meters at most each year. by

contrast the huge ice sheets in greenland move up to 7000 meters a year 35 times faster. but the laws, the flow they follow are the same. so the information gleaned in the out could also help scientists better understand the glaciers of greenland animals and even shots have always migrated to foreign ecosystems. the european stoney has spread to north america. south africa and new zealand posting is threat kim, date of birth species. the asian come to europe and north america, largely due to the exotic head trade and sport fishing. the cane toad has laid all the way towards, crania, originally introduced to control crop, has now taken its toll on domestic animals and in europe. autonomy is

causing massive problems in its new habitat. the depths of lake constance are no home to a creature originally from the black sea. this is it's fascinating and terrified, as when there aggravating and annoying that we're not really sure what they're doing here. the quantity muscle, if disrupting the ecosystem of lake constants, an important source of drinking water and biodiversity coast of booth and echo is a commercial fisherman whose halls have been declining over the years. and his fishing nets are increasingly clogged with clog muscles, emotions, and dash off country. they've got very sharp edges and depend if you're unlucky and dredge up a lot of shells and one catch in the entire net is covered with these tiny hold. of course that reduces your cash cut,

and the congo muscles are too small to eat the loose and there are no use at all. really. the clunk of muscle was 1st discovered here in 2016, the probably migrated by, latching onto the homes of boats as store ways for the scientists at the institute of link research and long and hawk in germany. much about the muscles remains a mystery through close monitoring between 1st want to find out exactly where they're colonizing the lake and how quickly they're spreading. if i, if, if we're going to a relatively deep spot now to take samples of water depth of around 180 meters, him on. it's a location where we found clog muscles in the past before the program muscles don't usually live in such deep water. is often find the log in now they seem to be able to survive on the food supply down there and grow in the low temperatures

their tune up and suddenly the clouds gather and the wind picks up a change of plans. the boat has to turn back, the researcher is designed to lower the sieve to collect samples and shallower waters. it's dragged along the bottom of the lake like a sled, collecting everything in its path over a distance of 50 meters. the meanwhile, is looking in water samples, set off for now seeing muscle larvae and winter to which used to be the case of quote, muscles reproducing even in winter, explains why they've spread and colonized the entire lake so quickly as you can see it here, all around the lake dens populations of $500.00 to a 1000 specimens per square meter. this is where the muscle has already taken hold fish from oscar pipes. they're also affecting drinking water supplies because they

close up the lakes extraction pipes. the concrete walls of the waterworks are covered in clusters of mussels. ah, the facility had to hire for additional people to keep them clean. the for invasion was already a growing problem last year. it's been almost an incredible amount so much more than we used to catch. all i see now is quite a muscle. they all have this round belly. meanwhile, they pose a threat to the entire ecosystem because it's all got the sauce is a very big and real concern comes from the fact that there are a filter feeders on. they get their food from open water from feeding on plankton and if they too much plankton, there's nothing left over for the other creatures that rely on them. especially

white fish, which are the main catches for the lakes, commercial fishermen, the. i don't to help them fish for the fish goes off, and my hope is for the muscles to be controlled naturally by a parasite or disease which would level out their number sanford, room ball. i live in the delicate balance of nature has been upset. researchers at the university of constance are also hoping the link can handle itself. biologist, who is on and lim, knowledge as a whole topped, have anchored cages at different temper. ah, i want to use the cage if you compare abundance matters inside and outside of the katy's to seeds are influence of water burst. muscles. waterfall might help reduce the muscle population in 2002 scientists using the same

experimental setup, found that coots, parents, and push are dogs that spend the winter. it may constance fed on muscle. they fed unsee bro muscles, which are about the same size as clog muscles, down to a depth of about 7 meters. letting shines into this winter is an idea for our experiments because we're having a very mild winter. so does not a lot of the diving birds from northern europe don't need to come to like constance to feel free to came back at the lab and lung an organ tossed and zanna balance team is analyzing samples from the morning expedition. the clog muscles are sorted and counted according to size and age. there's a lot of the very smallest muscles here when it's given the amount of young muscles and watching the level increase. i can't help it worry what it will be like in a few years. piano, the clunk, muscle invasion doesn't seem to have reached its peak. the tiny mollusks will

probably continue to plainly constance for some time to come on that. so for today, we'll be back next week with another exciting addition tomorrow today, until then, by, by the lose lose, lose. lose the
