welcome, sick label, 3002 veterans who have fled that home and making a new life in switzerland. but the hurdles a great, the homesickness in kenya, a lake is following villages. but where does the water come from and how is it affecting life and the region and china delivery drivers, work long, stressful hours, very little money. how do they chose fancy a quick and tasty bite, but there's no way to go. the current pandemic casino boom and delivery services around the world. food curry, as rush around, bringing a plethora of meals to customers. the global food delivery sector is set to reach a 126000000000 dollars this year. by 2025, it will rise to more than $190000000000.00. the biggest market is china followed by

the us. but just the fraction of the money goes to those making the deliveries. they tend to low wages and work long days and nights. that lead many to take to the streets and colds, the better working conditions and an end to exploitation. you can call me wang and i prefer my real name not appear in this report. so when someone asked what i do for a living, i say i'm a food delivery guy. and other people have sundays off or they have vacation time. we don't have those privileges licensing, it's very stressful for you to come with the. it's not nice for me here. are you rarely the customer say thank you this. all right, perfect. and then there's that moment in the evening when i see how much i've actually earned. and so when invite us into his home in the

chinese capital he had to work until midnight the previous night. so we need them at 9 am. when he has to share a room and a bed with another migrant worker, they have no heating. when it reaches freezing temperatures outside, i don't have running water inside. when that happens, i have to go to public restrooms to brush my teeth and wash my face. i actually he pays the equivalent of 65 years a month for the roof that says he 7 year old migrant workers since every says his wife and 3 children back home. so only when i make 58 years a day, do i earn more than i did back home at the factory. but it's hard to recall. i swear all day long. you know, those are his job requires him to work at

a quick pace for the work determine how much time you put each trip they assign delivery sometimes they pay decency, but often they don't wanna do that. cause i said, i need more than 30 good orders a day. i don't, one's listed here are all bad. i get just $0.65 per delivery and he almost never ends more than 2 years per delivery. and when it comes to the strict delivery deadlines his teen life, i for sure, a cojet being late leads to pay deductions. so again, that's one of the current rule is that for every 5 to 10 minutes of being late, my pay is reduced by more than $0.60. now you don't already sweating profusely. this time it's because of time pressure on the water. i have to

wait here until the food is ready, made in a very stressful the afternoon as a stressful time for all of phasing. these no time tickets for yourself. oh, go out to eat. meals can be delivered for as little as the equivalent of 2 euros and $0.50. one has 10 deliveries now for being late. he could lose more money from deductions than he earned from the deliveries. the about 7000000 foods livery workers are employed in china. this recording is from the beginning of march 2021. it's a person, it's against the industries low wages. this is 10 go chung. he advocates working conditions on the 31 year old as the delivery worker himself. his online videos course our attention. they showed him providing a to his colleagues with communal dentists,

very organized and driver's 10 go, john united people who had previously been fighting on his respected by everyone then suddenly his online videos were nowhere to be found. at the end of march 2021 . he disappeared in our contact with him, was cut off. 2 weeks later, his parents received a message from the police station where he was being bused to wang, his 2, racing against the clock to deliver those 10 orders. the one who made all those deliveries for longer and i called the customers for my moped so it worked out now i'm really sweating. they're cheap labor and makes life comfortable for the emerging middle person. but mostly just

all i do is work. i don't even know what i do, who i can me if i had time to come with when your poor people look down on your view as incapable of them. that's a phenomenon here in beijing. so everything is all about money. the most commonly asked question is how much money did you earned last year? me? i hate myself for doing this job, but everything i do for my family. back in october, 1950 chinese troops invaded tibet and took control of the small mountain kingdom. over the ensuing decades, chinese authorities responded forcefully to any uprisings, including that of 1959. thousands of tibetans lost their lives. countless monasteries were destroyed. in 1959 to bet spiritual leader,

the dalai lama went into exile in durham in northern india. widespread restrictions mean tibetans can only freely practice their religion and culture outside of their homeland into itself. tensions between citizens and the chinese authorities. regular bounced of unrest most recently and south and date, and 2012. political repression has driven many tibetans to go into exile with little hope of returning home. the buddhist traditions of his forefathers are extremely important for tens in originally from tibet. he now lives in switzerland. he fled his homeland in 2013 and started a family here to hear in detroit life. and i would like to stay here in switzerland buying all i want to work as a care assistant and provide for my family. when for mind, if i just want to live

a normal life, i normal lives live in the living. tens in dreams that staying in this with the village and building up a new life here. we've changed his name to protect his identity. his wife also fled from tibet. the couple of broken old ties with the homeland. i was a fear of a kind of contact me mind for me that i have no contact with my family because i didn't want to call so many problems. my familiar with my family doesn't even know that i have 2 children, that it makes me very sad and i'm very homesick to the hungry. they've had 3 occasions for asylum, rejected this with authorities believe tens and came here. fire another safe country and say he should seek, assigned him there instead, without papers. he can't work, even though he trained as a care assistant in switzerland. but they've at least found friends here via fossil and down from them to be tried to help them through the tibet friendship

organisation seats. and it's help there's a support network, for example, where individuals can befriend refugees and help them with everyday challenges. size that so often many tibetan flying confidence in prayer and meditation and this buddhist monastery. and i was dr. north of fear. it provides the perfect setting, tens in love, this place. it reminds him of his youth when he lived in a monastery and was happy. honestly, it was wonderful. now, you get up early in the morning that make your bed have breakfast, play with your friends. for the speed in a caffrey life that ended when chinese security forces began harassing the monks, they initially tried to take a stand, didn't talk, stood and say on the authorities came every day, putting pressure on us and restricting our freedom and hobbies. so i put up posters

to protest and took part in demonstration. it's mock, he says, friends warned him that the police were looking for him. that when tens and fled the average, the mon street knows many similar stories. basically they have more full right to religious freedom. so that's maybe if you asking them against the government that you put in the jail. we wanted to talk to someone from the chinese embassy and ben. but our interview questions went on onset by ging views, tibetans who have fled to switzerland as opposition activists. china is focused on expanding it economic ties with switzerland. the 2 countries have had a free trade agreement since 2013 bilateral trade has grown steadily since then. for switzerland pursuing economic interest while standing up for human rights, the difficult balancing act, he now paid to name and china is becoming increasingly authoritarian and more

assertive of its economic interest and refugee policy listening. so switzerland needs to respond to that and by more coordinated in its approach at 14, not long ago tense in went to the chinese embassy himself. he needed papers to confirm he from tibet. i'm all i went to the chinese embassy just once to get an id like to hold, but they started arguing with me on the phone and i felt threatened to disprove the miserable the end to see refused to give him papers. he still feels at risk from china. this, with the authorities of not granted him asylum so far. and he doesn't know what will happen next. every year we humans produce a total of around $2000000000.00 tons of rubbish, according to the world bank by 2050. this figure will rise by 70 percent to

a shocking $3400000.00 tons per year. waste is literally everywhere. few areas of our planet remain unaffected. what can be done? for global ideas? we went to ginger in her room to find out how the economy is breathing new life into the desert that the these chickens are engaged in important work. they produce eggs like any other chickens, but with the help of their owner, they're also working wonders forming the desert. and this entire area of the city of ginger out into room is dry in the bowery. there's almost no rain, so it's hard to be suitable for farming. green plantation is flourishing mandarin trees, leading with fruit cover, an area of 30 square kilometers. it's all thanks to the chickens and their source

val, owner the most. we've been farming in the desert for many years. people thought we were crazy at 1st. obviously, you only normally grow fruit and good soil. but today we're producing record numbers of mandarins right here in the middle of the desert name and not enough. it's the chickens that have made the desert soil fertile 6000000 of them in all. at 1st, pasco, marcia was only planning to sell their eggs. but when he found himself ankle deep in excrement, he came up with an idea. why not use it as fertilizer? he adds all the leftover chicken to the birds feed on corn. they're quite picky. the this was, this is what's left over. yeah, we used to burn and up or throw it away. but now we use it to produce bio char. and

that's the central element in our regenerate to fertilizer boscoe macias burns, the organic waste in a controlled process called paralysis. it's a centuries old method used by the indigenous peoples of the amazon bio charges rich nutrients, an ideal source of food for the trees. but then he adds the chicken excrement to, along with a few other ingredients, turning it all into fertilizer pellets. some of them he uses for the mandarin plantation. the rest he sells music, but this circular economy allows us to make everything efficient. it's really nothing new. it's actually the way that nature work sooner. listen, the principle is simple. resources are used in re, as long as possible, saving money and avoiding waste. unlike normal methods in the capital,

the german development agency g i. c is advising the pool of in this vironment ministry on how to encourage more businesses to move to a circular economy. the program is financed by the german government, international climate initiative. your practical level and i'm very grateful to be part of the project and, and for the opportunity to support an initiative like the law school, pull it up. well, yeah, it's just, it's a paradigm shift, a whole different way of thinking. you know, we need to provide help to ensure the shift will be successful. i do that. i mean, it's a good starting point for that is to talk to business owners. you've already made the change to learn from their experience like miro combo or what about kind of have a he's a chef in lima and buys all his vegetables from an organic farm on the menu today. fennel, atlanta,

the aroma of fennel is intense. delicious. he uses every part of the plant, including the bits, other ships, and normally throw away like the flowers. i'm going to take some of these flowers. they have a great aroma. chinese palm euro is founded an initiative called corey, which means treasure in the indigenous casual language. part of the idea is to train other ships to use food in its entirety. norma kong young that we founded cory with the aim of making peruvian cuisine more sustainable. optimizing our use of food and the aim is to avoid food waste and hunger in peru, he takes his freshly harvested vegetables to a local kitchen. the staff here are grateful for tips. they work as volunteers,

cooking for the needy. they can't afford to throw anything away, a meal here, costs one euro, but for those without an income, it's available for free. shows the cooking team a new recipe of fennel and beat root salad that uses every part of the vegetable. it's served with integrated made of fruit p. o and a kind of pepper corn made of dried papaya seeds. you can look at the fire, we can spin out the seeds wonderfully without losing anything. they thought normally the seeds and peel would land in the trash. here they end up in the sauce from the florida. the fennel flowers provide the finishing touch. the remaining medicine, one of the things on sample, i'm happy and grateful me the throwing a lot away before and now we use it and don't waste anything this yes or no,

showing others how it's done for moscow. mercy also wants to share his idea for fertilizer and see this form of circular economy take off elsewhere. if fruit can flourish in the desert, the possibilities are surely english. were bringing environmental conservation to life with learning packed by the local ideas. deutscher, fellows environmental theory show you how climate change and environmental conservation is taking shape around the world with teacher resources at the ready educators can start right away. knowledge sharing, download it now for free. the global ideas, learning east africa has been hard to explain. natural disasters after years of drought, low cuz destroyed harvest. heavy rains then flooded fields and villages and dismay

. the neary gong go. volcano erupted, displacing hundreds of thousands of people. repercussions were felt throughout the whole of the east african rich system, which stretches from the red sea to southeast in africa, is also home to kenya's lake nikoto. the once natural paradise is become a menace to local people and animals. lucy, me and says she used to walk along here when she was living near lake and crew. now she can only come by boat to the spot where her family's home once stood. the 54 year old has 3 adult children. last year, this area included farmland and the shore of lake. now young man cast their fishing nets here in the hope of finding anything of value. the lake has swallowed up the entire hon. nothing and lucy's life is as it was before

a bay. lemme due to the lake. no terror kept rising with what it all began in 2020 you might. then in march of last year, we had to move out because the water had reached a dangerous level. suddenly we were home and we raised poultry. but the chicken has died in the water. now i'm penniless and have nothing left to my name was the to me in one way. like now who is a paradise? it's in a fantastic location in the middle of the national park. that's the unesco world heritage site and it's just a 3 hour drive from kenyan capital nairobi. it was always popular with tourists, but for the past 7 years, the lake has grown steadily. the water level is now twice as high. lucy and her

husband had moved to a hut just 5 or 6 square meters inside their old house, had several rooms their children are having to support them financially. see me didn't equal to an agent my new, but i'm not the only one whose house has been submerged. montgomery my to my neighbors have stuff at the same phase genie si fi. but in the room this life you can't cook probably come out. will know if you know when you, but you can't sleep properly because nothing. with the data breach several 100 others who lived on the banks of lake no who have had to move to emergency accommodation. this is once the main entrance to the national park, the number of tourists coming has also declined. this is the most point of the picture. and from here to the 100 meter, to the actual lake. so this is beginning of the woodland night has moved more than 3 kilometers. we joined joseph from the canyon wildlife service. the state agency

responsible for conservation. he's been observing the changing landscape with great concern. the level has gone up more than 5 meters. initially the lake level was about 4 meter, but now we measured in december to tell me to 10 metals, but now the lake level has gone back by half a meter. so it's about 9.5 meters. initially we had a few fresh water, but for example, we had about $117.00 africa. she goes, i forgot to see she got to see don't fish, and mainly found in fresh water system. it had serious consequences for the entire park. roads have had to be relocated, animals and birds are struggling to find in a food and suitable breeding grounds. for many of the flamingoes, for example, to leave. like nicole root is just one of several lakes in kenya's, great rift valley that had been effected. but what's behind these changes,

and could they to stabilize the entire ecosystem? experts are still debating the cause. environmental activist elizabeth, one yeah, believes there's no easy answer when we just said the level of water and it could be attributed to our complex and made it into fits of climate change. lenses change and geological factors. we tend to a number of social economic impacts and also hydro, under political impacts from the back to lucy and her husband, they say there's been very heavy rainfall in recent years. dear friend, victor ne, in do, has also had to move house. he and family used to live next door to lucy. now their neighbors again. victor lives with his wife and 4 children in a corrugated iron hut that he felt himself. he pays $20.00 rent a month to the church that owns the plot of land on the bottom we will. yeah. and

these, those, as you can see, it is very small and i will not even run till i talk to their management was in charge. be allowed to meet me at that time. so i realize that so much of the press i really do in my life, please still thinking so thank you. because when i see the way i was and see where i am and maybe count of where i would be that i see great, great loss for me and my entire family doing the end do struggles on day by day. he does his best for his family, but finds it hard to stay positive. lake coral continues to shimmer with all its beauty and attract tourists, albeit in smaller numbers. but the entire area has changed. meanwhile, the younger is deeply unhappy. she dreamed of enjoying her retirement by the lake.

now she faces an uncertain future. o 2 children. one giant problem would be jason how will climate change affect us and our children learn more at d, w dot com slash water. that's all from us that global 3000 this week. don't forget to send us your feedback, right? to global 3000 at d, w dot com and check out how facebook page t w. ideas bye for now. take care the the

the the, the the, the streaming services threatening our democracy with watching media scientists from germany is the algorithms used by netflix and co turning into mindless justified research isn't arguing about the future of television tomorrow today with next d w because far

away more in film with their violence trauma and that's the nation or the informative or spectacle. we take them on the 2016. 0 the how are we? can we carry effect climate change? i mean, one of our 4 station in the far as carbon dioxide emissions have risen again. young people all over the world are committed to climate protection.

what impact will use because change doesn't happen on it. don't use, make up your room, mind w. need for mines in times past people with gathered around a fire to tell each other story in recent decades that home entertainment has been replaced by a tv set. but now we're on the brink of a whole new media universe. ah, welcome to tomorrow. today you will science show d, w. the traditional or

linear television has a fixed schedule of films, series and document trace. but in the new media world, you can watch what you like when you like. at any time of the day will drive the number of subscribers to video on demand services is steadily increasing from 170000000. in 2015 to a projected 1000000000 plant by 2025 and the number of paid subscription to the big streaming services is also rising. another sign that spells the end of traditional tv. we want you to know how you watch movies, tv series and shows like tomorrow today, maybe online or in traditional star in front of the tv, or maybe some different way. i really need to put 3 rides. i prefer to watch tomorrow today on tv, because then other members of my family can watch along with watching shows

together is quality time with the whole family. like you can be posted. i live in new mexico and like to watch both free to view and pay tv, just my streaming subscriptions. the. sorry, how you doing ts, right? i mean much magazines like tomorrow to day on tv, but the films on tv are usually outdated as lots of commercials and are often repeat. now that the internet is available, i prefer to download and watch them later when i have time. now. so colorado doesn't watch free pay tv at all. he only watches online streaming. so what did media researchers have to say? once upon a time, there wasn't much to watch on tv. you really had to put your mind to it if you wanted to indulge in mindless channel surfing today,

things couldn't be more different. the age of video on demand and binge watching and what is it doing to us media researcher, marco's kalina, is extremely critical of the trend toward digital binge watching. he's written a book about it called stream land. ah, the author, the, the on demand video, i believe that netflix, amazon prime disney, apple tv and the like, threaten our democracy on monday card. there's permanent shopping us about the maturity and self determination. yet, when in the, from our tracking and filter bubbles effect to keep us from experiencing anything alien to us. but it's all about me. my taste. i like that supposedly. mine's not long ago, what we chose to have blaring from the one screen in the middle of our living rooms was a matter for negotiation among family members. these days,

linear tv is getting less and less viewing time. the 85 percent of young people in germany have access to a streaming service, endless series countless seasons, and after the cliff hanger, straight to the next episode. not a 2nd to wonder what may happen next. live in that man either because when we watch, we are watched by anonymous algorithms on the basis of our viewing behavior, we're categorized as a particular type of netflix persona. recommendations are then made to us. on the home page, we're only shown what's currently popular or the stuff that they want to become popular lead. it's all about sex, it'll danger. and here it's about the end of a world about crime in familiar topics that go down. well, we the majority of netflix viewers, and so netflix is tast populism is creating a new digital popular culture roy doing digital

a for school would have been netflix has taken the monitoring a viewing habits to a new level. it's their recipe for success. but will it really replace our former viewing habits? gant holland bagger. media researcher from my book says the trend isn't as worrying as some might think. of her sounds in there's a type of television where it doesn't matter at all and you wanted to reach that site one cc'd on task. another streaming services have built their business model around 1st. but on the other hand, i think there was always and still is a certain type of television that simply calls out to you. i want to see now next week it not any other time. those include formats like live sports broadcasting classes and for me and we live for watching football game from last week. nobody does that laugh kind this saturday night movie is also likely

to stick around for a while. this just something cosy and old school about it. and t v series that aim to solve real life crimes will only drive yours when there's still a chance of catching the suspects. in germany watching the tv detective series ta taught on a sunday night is still a ritual. the show still attract millions of viewers. the desktop ought to my interest in the board is still, you know, just perience through clever cross media coupling. in this case, twitter or twitter makes it possible to make this, we show what you could actually be, watch it anytime. as anyone demand on television event through twitter, it's an event tied to a viewing chart. in the past, prime time viewing was planned ahead. netflix users no longer have to think about

when a show was on. but this automated personalization of programming could have negative side effect fiddle to me with friend types of education as to the variance in the unfamiliar with material. i wouldn't usually see anyone helping with topics i wouldn't normally deal with that. i'm an educational against when i step away from myself and open myself up to something that doesn't just reinforce my worldview, that netflix does just operate with every 2nd to minute dreaming. wants to affirm my sense of self, my taste, world view, preferences, box me into my very own viewing. present me skipping this the things i'm pleasure driven consumers who wither away and their feel should become less able to comprehend the world's complexity. the once frowned upon. indiscriminate tv junkies suddenly appear almost like last heroes. out on an

audio visual stroll, they let themselves be captivated and make discoveries outside their usual areas of interest. having that conclusion, this type of home entertainment is far from over. this and other sounds in the us as we all know that television is the classic sit back and zone out media, the media where sometimes you don't even want to think about what i like to watch tonight. netflix has begun to take this on board and the streaming provider has begun offering linear programming and friends on a trial basis. for those who find it tedious to flip through the whole netflix catalogs in the network cut a local to carbon. ah. so announcing the death of television may be premature, streaming is likely to replace linear tv or even cinema. it's just

a different way of consuming media. a new facet of an existing landscape use from the media jungles to the labyrinth of lies beneath the 3. busy different forest found mainly in northern europe, siberia and north america. se make up around one 3rd of the woodlands. then there are rain, sorry. these are the forest 10 tropical and sub tropical areas on either side of the place in which both the world's greatest diversity of plants and animal species, deciduous or broadly mixed. foreign are found primarily in europe, eastern asia and north america. and it's in one such forest, but scientists have eat dropping on the secrets of the wood wide web.

the since ancient times, the forest has been a place of magic and i often feared by many of our ancestors. today we no longer see our shrinking woodlands as enchanted, but still we only understand a fraction of what goes on there. the one thing is sure their home to a vast array of helpers that are working hard to ensure the tree survive. in the fin fingers, nature park in switzerland, mckenna painter, and her team are on the trail of fund guy which thrive in force. soil in play, a very special world. when on here to also on be, if you remove a little layer forest floor, you can see these tiny white threads everywhere. i say there fungal threads hold hi fi. so the ones that are visible to the human eye or the white one,

the vice the thing. but there are much minor threads to piece together. they form an entire cluster in the forest floors full of fun guy, high feet full of full from from p. me there reach is truly incredible. filaments of a single fungus can spread over 100 square meters. once species alone can proliferate across the forest floor, and there are $1000.00 different species and total fund guy network under one, hector, a forest soil weighs about 6 tons, with a total length of a mind blowing 100000000 kilometers 1000 meters, the sun go hi fi my below just one square centimeter, a forest flor ah, with a fungal filaments meet the delicate tree roots. this is where the magic happens. the fungal filaments enveloped the roots. some even penetrate them. fungus

entree connect in the field from the chance again home fungus and the plant train was one another, asked of the fungus gets nutrients like nitrogen and phosphate from the soil, which it gives to the plant t. and in return, the fungus gets sugars from the plant, which the plant can produce with photos, synthesis. this is called micro rises symbiosis, the mutually benefit from one another, and couldn't survive without each other on the phone guy and tree roots together form a vast network in the forest, which some have dubbed the wood wide web. there has long been indications that phone guy and trees can exchange nutrients through this network. and the tree can also show new trends among themselves. it's a romantic notion, a kind of harmonious woodland coexistence a tree in the say, for example,

might benefit from the sugars of a fellow tree. and it's funny or spot for hungry young saplings. but doesn't really work like that. it's such a neighborliness essential for the forest survival that's what martina painter and her team want to find out in an experiment that's unusual and rather ingenious, they're planting seedlings in the shade of the forest. around some of the seedlings they place a membrane in the soil that's permeable to fun guy around the others in impermeable membrane. ah, they then administer traceable carbon dioxide to a nearby adult tree. to do this, the researchers wrap the trees crown with the plastic tarp and pump that c o 2 inside the trees, the photo synthesis to make sugar from it, which is also marked and can be tracked by the researchers.

ah, sure enough, the lab results show that sugars from the adult re travel to the seedlings and the fungus permeable membrane. but the roots of the seedlings didn't transport. the sugars further form and hardened us. these are to come up. we found is that the sugars stay in the roots in the michael rifle, fun guy, and a tiny amount in the very fine roots of the sampling. in a few cases, we also found the sugars a deeper in the root of the plant spare during the plot. when god can and we found none at all, and the needles also know if there is a sugar transfer here, it's only in tiny amounts. most of the sugars stay in the fungus and peeps. and what about the adult trees near the one that was pumped with c o 2? the researchers also found sugars with especially marked carbon on those trees

routes. but here again, the trees didn't absorb it. ah, so it seems that the transport of sugars from tree to tree by a fungal network does not play a significant ecological roles. nevertheless, a tree releases about a 1000 different substances into the soil. they could all play a role in the forest ecosystem, and the co existence of microorganisms fund guy and plan, ah, the trees probably communicate with each other with some of those substances. but little is known about how and when they might do this and what role the process might play in the forest ecosystem. nicole read so people to me, we already know quite a lot about the interaction between micro rice will phone guy and plant that off. we understand quite a lot about this exchanging but the interactions to take place from one tree to

another via fund guy. the research on this topic has only just begun stating on them on from the for sure. perhaps the forest can best be understood as a kind of super organism in which many factors are play. what really goes on in the wood wide web is still largely a mystery. a mystery that martina painter and her team hope to unravel. but for now, it's safe to say that the forest continues to keep many of the secrets to itself. by the way, not yet fund guy fossils discovered in the democratic republic of congo was found to be 250000000 years older than the previous record. hold on, scientists keep making sensational discoveries of other fossils to such as woody mamma's and of course dinosaurs looked at all the animals from that primeval era,

actually die out gothic book from colombia had a question about that. are animal species present today that survived the age of the dinosaurs? some 66000000 years ago, a 14 kilometer wide asteroid slammed into the earth, triggering a mass extinction. within seconds, the space rank vaporized across the earth. fires raged, and volcanoes erupt. it within a few days, the earth was blanketed in darkness. the deadly ice age that followed lasted for years. acid rain transformed the ocean's vegetation died. 3 quarters of all species were wiped out. today's reptiles may resemble many dinosaurs, but in most cases they have little in common with their forebears. unlike

crocodiles, a pre historic relative of the crocodile emerged 250000000 years ago, and crocodiles are ultimate survivors. they eat almost anything and can go for long periods without food. turtles are also one of the oldest living reptile group. the earliest known turtles swam the world's oceans 225000000 years ago and looked remarkably similar to those solitary, ancient creatures that exist today. to sting rays have roamed the oceans for even longer. these primordial creatures belong to the cartilage and fish, family and sharks. they were already among the top predators of the oceans in the age of the dinosaurs, the catastrophic consequences of the asteroid had little impact on shark biodiversity. horseshoe crabs haven't changed much in 150000000 years. that's because these living fossils can survive and water of

varying salt in this and warmth. birds evolved from a group of dinosaurs, survived, thanks to their feathers, chickens, and ostriches, are the closest living relatives of to run a source, rex. sounds improbable. just compare how they walk. if i was what is read, why do you have a question? you'd like us to send it in as a video, text or voice. if we feature it on the show, you'll get a little surprise from us as a thank you. come on the news . you can find more fascinating stories from the world of science on our website and on switch and i, but now it's time to take the plunge. in the mid 900 century research,

i still believe that the deep sea was the rest of life. today we know that the depths of teeming with an amazing diversity of species. and so far we've done the last 5 percent of the deep sea. but it's not just the ocean set him to fascinating across the creatures. they come to the border between germany, austria, and switzerland. and this underwater world is populated with some very interesting residents. the temperature is around freezing, but that isn't going to stop all bat thompson and tino de chair from taking a dip in the water. isn't it too cold? good. now you know it's grade. it's warmer in the water than out of it. what are you wearing to stop you freeze and hold on the, on the screen a she on russia. i'm wearing thermal underwear and a fleece. the understood over at a new

a well then then i got on event jacket to keep my upper body and kidneys warm. play tight tom open car put on to the new dentist and then a dry say to which is waterproof us at the feet pocketing. so only our faces are going to get wet for over a year, the 2 divers have been monitoring aquatic life in the depths of lake constance. there are not scientists, but photographers fascinated by what goes on in this murky underwater world live. and i want to show that the lake isn't as dark and dormant as people think this minute teeming light. and you just have to take a closer look. it was a sty risk. our aim is to capture these images and bring them to the light of day yona soap, replacing the name. the aim of today's expedition is to track down some tiny crustaceans known as mice. his for him, also known as a possum trim. there was

a little miracle to stay in winter. the water is clear enough to see the aquatic life still active. at this time of year the 2 divers have gone on over a 1000 expeditions to the depths of lake constance together in all seasons. today they come across a catfish, one of the lakes, largest native predators they also encounter an eel, also native to these waters. but they also come across a number of invasive species like this north american spinal cheese crayfish, which is devouring vocal aquatic life. and zebra mussels, which have only existed in lake constance since the 1900 sixty's since then,

their population has exploded. finally, the divers find what they're looking for. mice. his shrimp native species now feed on these crustaceans, which arrived in late constance some 20 years ago. the invasive species also fascinate biologists it using his social that seen on the left has been researching the biodiversity of freshwater rivers and lakes and switzerland for 25 years. today, he and his colleague are collecting samples from the royce river. this, here is another intruder. the scientist is identifying more and more invasive species here in switzerland and in more lakes and rivers. does this, that was, this is a killer shrimp. it wasn't here 10 years ago. but now it's an almost every sample. it is also in like conduct board and it's been there a bit longer and it spread extensively. it's just like the quag ma,

so it was 1st discovered in lake constance 5 years ago since then it spread along the shores of the lake and also on its bed with significant consequences for the lakes ecosystem. to ask that, you know, at 1st we thought it wouldn't make much of an impact as just once the, the muscle would replace and others. but it wouldn't change the ecological balance . but it's turned out that this species can live in far deeper water and has completely altered the lake bed. the board on campus is no native muscle lives in that exact minish. it's not replacing anything sort of thing, but it's completely transforming that habitat. turning a sandy bed into a hard substrate when it might be endangered. as a result, we don't know yet apply just kind of know nissan. but this development clearly poses a threat, a growing threat, because once new species settled, they generally start to spread cedar and eventually it's as many other bases

now in lakes in switzerland were 1st found in like constantly the killer shrimp and the speaker muscle land. if they traveled here along the line and then spread across the country, what happened in like constance is a blueprint for what could happen in like service and elsewhere, and in opposition to the entire ecosystem of late constants is changing. that to photographers have also seen it with their own eyes. auto body, all had carl, if lay a few years ago, the floor of the lake was bare. box now was covered with a dense layer of mussel and hollins, per se. visually, it's very attractive us. we found my shrimp and tiny creatures between the muscles still a visa through shifted and what was going to happen next? vehicle today aquatic life in lake constance includes many invasive

species. well that hans and has published a book recording these encounters in waters close to home. and i think the guy who today, thanks for watching will be back next week with another edition of tomorrow today. until then, bye bye. ah, ah. the news . the news

the news, the news the all the dream, the clues, far away more in film with with their violence trauma and fascination. are they informative or spectacle? we take a look on the grid parts 20 was on the w. o. ah.

was young immigrants they know the police were stopped. they knew that the route is not a solution. they know their flight could be going back. not an option. peace ma, i'm on and they are stuck in the spanish border area. alongside other young people there waiting for a chance that will probably never come. shattered dreams starts june 18th on d. w. the in the,

in the book all really feels ah, jewish life in europe. ah, that's what film producer and journalist could minute are exploring. delving into history and the present. ah, some things are painful, many or surprising. everything is important because life is so much more than what you think, you know. i would never have thought that could be live. so i remind myself because i grew up in a completely different way. broad explorer and stickers. i jewish senior, the 2 part documentary start july 5th long d w. ah

ah, this is the w news coming to live from berlin. a son of relief from germany's political establishment after the far right fails to win a key state election. americans, conservatives fight off the challenge from the populace. alternative for germany party will bring you all the latest election reaction and what the result means for the national election in september. also coming up.
