sewing potholes on what was the francis scott key bridge and baltimore. in the blink of an eye they and the bridge plummeted into the water's beloved. divers are now searching for bodies, carefully maneuvering their way in the twisted labyrinth of iron and concrete. tonight, what we know about the investigation is shipped out of control, the bridge that stands no more. i broke off in berlin. this is the day the, this is no ordinary bridge. this is one of the cathedrals of american infrastructure wake up here, the bridge collapse when you're thinking how you think they'd have things that it's not been happening. there really is a few things that are scarier than a loss of power here. it's all that large. the main thing they gotta

do right now is get that shipping channel open is going to be a thorough investigation. it's going to be a long tragedy like this. you know, we learn from these mistakes also coming up the subterranean schools in ukraine. after the pandemic pushed lessons online, we looked at how war is now pushing the school. children to go underground is safe in the subway because there are explosions outside. and that was school could be destroyed at the browser. i mean, i would like to go back to school with a no more school, which is more from that and here which will to our viewers watching on tv as in the united states. and to all of you around the world, welcome, we begin the day with a shock of what we saw happen in real time, in the dark of night,

a collision of the waters and the massive bridge collapsing like a house of cards. on wednesday, us federal safety officers recovered the black box recorder from the cargo ship that struck the francis scott key bridge late tuesday night. in baltimore. they're looking for clues to why the best, the loss control ramping the bridge. just minutes after it had left port president joe biden as pledge federal funds to pay for the reconstruction of the bridge. baltimore is one of america's major ports. it's too early to predict the impact of this disaster on maritime commerce, but transportation secretary p booted you. he says, 8000 jobs are directly at risk. fully loaded, the davi is still stuck. nobody knows how long it will take to free the best off from the tons of steel that collapsed on it when the ship veered into one of the harbor bridges main pillars. for now, the accident is causing major problems in and around the port. with

a key bridge gone, a major audrey ray along the us, eastern seaboard, has been cut traffic will have to be rerouted for years to come, leading to clocked up streets in the greater washington dc area. but even worse, ship traffic in and out of port has also been stopped. the port of baltimore is one of the busiest into united states handling more than $52000000.00 tons of foreign cargo last year, contributing some $80000000000.00 to the countries foreign trade. it was access to the ports, blocked incoming vessel. so we'll have to rewrite those 2 nearby ports, including those in new york and new jersey. further north and virginia little further south. among the goods handled in baltimore steel and cars. the port has major role on role of facilities and it's the entry point for hundreds of thousands of cars per year. german automakers even have their own facilities inside the sprawling area. well, bmw volkswagen,

located at sparrows point just outside the main port. mercedes operates out of fairfield and won't be able to accept incoming vessels until further notice. us presence and fight. and let's to oversee a quick and strong response to the incident. and to ask the federal government for the funds needed to rebuild the bridge and port about the terrible on to for, to baltimore's, one of the nation's largest shipping house. it handles a record amount of cargo and last year it's also top port in america, both imports and exports of automobiles and light trucks. around 850000 vehicles. go through that port every single year. and we're going to get it up and running again as soon as possible. and local jobs are concerned in baltimore to we're looking at not having ships coming in for. no one knows how long at this point, you know, that's gonna affect the lives of, of longshoremen and stevedores. and the tug boat cruise um

that you know, potentially they are lose. they're going to lose income because there's no, there's no vessel traffic coming in or out of the port. bringing baltimore back. we'll take time for now. the focus is on investigating what exactly happened on the daily and the 1st place, and how to make bridges more safe to avoid similar accidents in the future. like correspondence, janelle do alone is covering the story for us in baltimore. she gave me an update on the investigation. since this happens, of course, there have been a lot of wild rumors are flying around from terrorism to cyber attacks. none of them grounded in evidence, a very important to stick to the facts here. as you mentioned earlier, the national transport and safety boards said that they had recovered the data recorder from the dalai, and that they're hoping to be able to use the contents of that reporter to piece

together a timeline of events. what exactly happened when and of course other they've also started interviewing the crew members of the dolly and i witnessed the event. we're also hearing that the single port in counter parts of the n t a c will also be traveling here to conduct an independent investigation. but i also want to highlight something that so transport secretary pete food, a judge adult said just now and every thing at the white house. he said that so a bridge of this age, it was of course, built in the 1970s would never have would start the impact of such a large of us. so. so really, what we're looking at here is a tail, perhaps of our older infrastructure colliding against modern commerce. and this is going to perhaps provide a moment of reckoning, especially given the role of this particular artery in logistics and commerce

here. and that was our janelle develop their reporting from baltimore with the talk more about what happens when modern converse meets own infrastructure, enjoyed by man who designs and builds bridges around the world. he also gets involved when there's projects go wrong. david mackenzie is a senior director from the bridge consultancy firm covey in the u. k. it's good to have you are with us. you're the man to talk to tonight. let me just start by asking you what were your thoughts when you saw the video? like we did of this massive, massive bridge just following, you know, like like a set of lincoln locks. it was horrible. i could still have a way to describe it, you know, to somebody to be on that bridge. and so your thoughts go out to the 6 people who are missing presumed dead, which is a trash the actually tractor, that's the 1st floor. it's not something you see as an engineer is not something you have to come some place and sense of ever seeing this week. we plan for bridges, we make all sorts of studies around them,

but this is the bridge engineers was like that. as a layman, when, when i saw the video, what struck me 1st was, how quickly we're talking about a matter of seconds, an entire massive infrastructure project. this bridge was able to just be the more did you see a, as an engineer? did you see any of the structural deficiencies at play? know what you're seeing there is you see a bridge and bridges without design bridges to resist ship, in fact directly or just low impact. what we do is we provide protection system to protect the bridge. i can't, what happens is that it's failed. it is not stopped that ship forbidding that bridge wants to ship it. the bridge i'm afraid collapse was, was inevitable. it's a shipping back protection system that is completely fail to the bridge itself carries traffic and catastrophic. well. but it was never designed to resist that sort of impact. the shipping back system should have done that. and that's what's

failed in. what about the the, the guard rail is if you will, that were built around the pylons of the bridge, looking at them from above. it seems that they were very small compared to the bridge itself. should. should those guard rails should they have been bigger? with that have made a difference in this tragedy in this tragedy. now, what was required was you have it when you look and finally breaking down the rich . you can see that there's a pair all the cool dolphins. a big concrete blocks in the water is 2 up, 3 minutes to downstream and they to find the channel. so you can see them in the words they, those are the only thing you'll pick to them, but they are those look at the recent house. but then i have a side of the bridge and the idea of a slate to find the channel. and they should protect a ship from steering into the break. but clearly they were inadequate. a modeling bridge would have been the system for an underwater island system that i,

that deflects the rich back into the travel stops if meeting the bridge. oh, it uses the facts to assemble and makes the ship run the ground. so when shipped from the ground, they stopped very quick. so what happens is you could the powers of land g into a basically there's use you think the lift the ship up the on, and that's what's missing. and so with that in place that you can design, which is to resist large impacts from ships of that size, but that was missing. you know, this bridge was opened in 1977. and if you were going to design the new bridge it today to replace this, when would you do a carbon copy or what would be different? you know, i think what's gonna happen here is that the, when the pitch was designed, the design for the, the 19 sixty's built in the seventy's. and so it would have been designed with ships of batch of the size of the time in mind me. and so therefore we have ships than what a fraction of the size they on our slower and said that for the protection system,

they would have been sufficient for that purpose. but nowadays what we would do doing the replacement design for this bridge will have the child step further about . it will have a full break protection system in place which will probably be alive and type systems. but if any ship comes be able to essentially it runs the ground, so he can only go through the channel. and just to say it would be a longer span bridge. so the child should be set back much further now. and was sorry, level higher dropped as well to stop any ships to ship some good potential beginning are, which is obviously a risk as well. so that will be a significantly different bridge in that location. when it gets rebuilt, this is not the 1st incident. what needs to happen this year? similar incidents happened. i understand in china and argentina. and should we be looking at the infrastructure globally and considering just the scale of our global commerce and should infrastructure augmentations and re fittings be made

a priority now to yeah, i think you're looking at instruct around the world which is being built and they have for many years a design lives, but bridges are quite long there potentially have to reduce what we discussed in economic life span. so what you're looking at here is a bridge we ship, you know, from the face of the evidence. we see staring this in the face was not the 1st because, you know, the protection system was not up to modern ships that were traversing through the ridge. so, so what we need to look at romwell, the middle places is what are the risks association with our infrastructure? what is, what are the accidental things that could happen to them that we should protect against? well, i understand, well those risks are clearly shifting back to some of the highest risk items or bridges. we know that and as you mentioned, the cult lapses that are being quite a few historically of this type of incidents. and it's all about how do you protect

the rate from vehicles, from ships aging that bridge. and that's what's going to need to be looked at when d o, the condition that the structures. so i understand that there was nothing wrong with this bridge. it was up to code in every instance. so there was nothing so in a defect on this bridge. but, you know, clearly they should come back. protection system was not up to code. yeah, they were there is big spending on the us infrastructure in the pipeline. but that will, yeah, they couldn't help prevent what happened last night. that's the sure they've been mechanically, we appreciate your time and your analysis tonight. thank you. thank you. as well to the conflict in ukraine. now, where officials say a russian attack on the eastern city of harkey is killed at least one person in wounded several others. the ukrainian interior ministry reported that russian air strikes it at least 3 residential buildings and a school. the city's mayor says a medical facility was also damaged. the attack comes as keith calls for more air

defense systems from the west to combat a search in missile strikes and recent weeks. the war in ukraine has destroyed many schools in foot line areas, but a new initiative in hurricane few cranes. second largest city means nearly 2000 people is, can now attend lessons in new classrooms, built underground in metro stations. the bell signals the stalks of another day. everything here is as you'd expect, children exercise books, board and teacher. but there is one key difference. this school is subterranean, built within the cock is metro. russian missiles could strike the city. it's a moment's notice. so it's better for the children salon below ground. is safe in the subway because there are explosions outside. and that was school

could be destroyed at the phase 1st graders have 3 lessons in the metro station today, followed by 2 more at home online. once they've left all the classes, take the place. this rotation gives as many children as possible the opportunity to learn in the classroom. of course, the children and we take dismiss normal education very much by normal, i mean face to face communication. so when the opportunity arose, to learn here, we will very happy children, parents and teachers alike. alayna says that it felt strange to teach you at 1st, but she still got used to me. it's what do you mean young noise? them? there are many sounds down here besides the trains, but we don't react to those anymore. they don't bother us anymore. new schools have now been built within 5 of call keeps metro stations adapted from what were once technical rooms and passages ventilation and video. cameras have been installed

throughout while teachers are helped by classroom assistance. psychologists, administrators, some of this was pretty new for all of us. so use it had been difficult at times, but there were no unsolvable problems. there was only unwillingness to solve them. we had the desire to create all of this. more than 2200 students attend these metro schools. but there was still not enough space for everyone. more than a 100 schools in khaki, if have been damaged by showing many beyond repair the underground schools are being built across khaki if to accommodates most students. but the children dream of a time when attending such facilities will no longer be necessary. i would like to go back to school with a no more school, which is more from that than here, which for now at least these metro and schools are getting children a small tice that the structure they wants to click onto it

with birth rates dropping dramatically. in japan, a company there has an else that is stopping production of diapers for babies. it says demand is simply not there. instead, it's re focusing on the growing market diapers for adults, in fact, pampers where your parents have out sold diapers for your newborn. now for about a decade, it's a surprising piece of data that shines a light on a serious problem. the number of births in japan dropped to a new low last year with within twice as many deaths as new babies board. if things continue that wage appearance population could shrink by 30 percent over the next 45 years. my next guest tonight has been studying japan's futuristic solution to its demographic crisis. she's the author of the book robotic sapiens, japan because robots, gender family and the japanese nation which explores the role of robots and japanese culture and society. please to welcome to the day jennifer robertson,

she's a professor of anthropology and history of art at the university of michigan. so glad that we could connect tonight. and before we talk about solutions that let's just talk about the situation is it is just how serious. and i, i say it's a crisis because we, we are always talking about, we always want to see growth. but this, is it a crisis, a demographic crisis that japan is dealing with to, demographically, yes. in terms of the number of the younger people in japan as a, you know, in, in contrast to the number of older people in japan. and it's interesting to note that the height of the japanese is higher in 1940 the population was about 78000000 people, but most of them were young. and today the population is about a 123000000 people. and about 30 percent of the population is over $65.00 and this percentage grows to almost 80 to 90 percent in rural areas,

including the area of the latest earthquake in japan. and you should call a prefecture on the japan sea coast. yeah, so what you're saying is basically the demographic, the, the, the chart has flip flopped in in the past century and it's 6 sets of japanese governments that they tried and been unable to encourage you know, the people to get married and have more babies. a very good question. well, during the height of the pacific war, roughly 1932 to 1945 in japan, and the government withheld birth control and also allowed soldiers to take 2 weeks for a lo, so they could impregnate their wives to put it directly. today in democratic japan, they can't do that. and so they are trying all sorts of options that are giving more money to the families to have children. and the idea was loaded back during the administration of the late a former prime minister of

a in 2006, 7 to introduce robots to the home. but that hasn't proved feasible at all. and i'm sure you're going to ask me, well, where are the robots injured pounds? yeah, that was going to just let our viewers. yeah. were, you know, we started by talking about diapers for adults and for older people. and now we're talking about the robot revolution that hasn't happened or has yet to happen as well. you know, there's a lot of mystification of robots in japan because i think japan is somehow right for the confusion of science fiction and real world actual tangible robots. and people tend to think that the japanese are sharing, you know, sidewalks, space and homes in the office places with robots. but that is really far from the case um, most of the robots you find, for example, in homes or small entertainment robots, or household security robots. the robots that are used in elder care facilities and

assisted living homes, take the shape of robot bath tubs or robots wheelchairs, and also possibly the most practical robot, the robot commode. but you know, many people have the idea that a japanese are being serviced by human wide robots which are not very practical at all. and i, i can't emphasize enough that humanoid robots are very expensive to build. there are quite fragile and they are not. and products, rather they are platforms for the generation of other industries, increasingly surveillance. and i hate to say this, the weapons uh, economy plus, i mean, we know if you've ever been in a nursing home, people who work there they, they have some serious muscles. i mean, you're lifting people all the time. i mean, and we haven't seen robots. do we that to successfully? why is japan pending and types of robots instead of just simply opening its borders

to immigration, like many countries in the west are due as well. it is in japan as always followed a practical solution to patently social problems and they pursue the course of uh, automation over replacement, integration after world war 2. however, the robot revolution have merged as imagine, back in the early years of this century. and so what's happening is that it's a lot easier to tweak a visa regulations, and these are criteria and to allow when more professional workers and also manual workers. now there is estimated in an estimated shortage of 60002270001 nurses in japan and uh, earlier in the century. nurses from the philippines and indonesia were recruited, but they have a pass, a really rigorous a language exam,

and many of them failed and got disappointed demoralized and ended up leaving. so what the government is doing now is working with chat g p t to create a translation services so that more for nurses will be able to communicate more efficiently with a japanese doctors and nurses. and of course their patients. that's interesting. i know back in 2007, former prime minister of a envision japan is a fully rubber tied society by 2025. you know, that is next year is artificial intelligence isn't going to see the rise of the robots next year or year to get as well. it depends what you mean by rise of the robot. some you for telling him a surveillance of weapons. absolutely. those are the most lucrative industries and nobody today in japan. but i, you know, obviously former prime minister and late prime minister abe's robotic vision was

pretty much straight, a science fiction and many job. and he said this is dated science fiction. you know, it's not feasible, it's not practical. but, uh, the, the, you know, the, the sensors whether they're touch or, or side sound that went into those initial robot experiments. we're all spun off into the mysteries that are far more lucrative today, including, you know, so the time is cars, drones, the japanese are now getting into the fighter plane mark. yeah, that's where i bought this specially surveillance on, you know, chat g p is, has been called a great uh, plagiarism machine and it is lawrence on data that is up to it, but it's also streaming data. so data today is capital and the some of these companies that are creating robots that provide translation services, for example, are also collecting that data and then simply them to parties. what i mean it's, it's fascinating when you think about it and it makes you wonder to if we're going

to see the, the singularity event happen this decade of the next decade. and if, if so, will the merge of machine and man will that make a difference? i mean, these are huge questions. fascinating. so glad we got to talk with you jennifer roberts and please come back as i have a feeling go be lots to talk about in the future. thank you very much for inviting me. it was a pleasure and i hope to come back. thank you. so today you can see use online and remember what ever happens between now and then tomorrow is another day we'll see you then in the,

into the conflict. so with the best in here at the munich security conference, as cynthia in security and conflict, providing the politicians on that side of the world reach this dangerous inflection point. my guess is we have the 2nd live experience of the highest levels in the us . nancy pelosi, well, who's come next don't this is not made of plastic. this bag

is made for me to pull. some is in bangladesh, it promises an economic boost. and so the load potential future without plastic but processing cubes is expensive, complex, and time consuming. so what's the load down on the golden natural flight? in 45 minutes on d, w, the old friends, new friends, can nature defend itself in case of an emergency? we cannot guarantee that we could protect munich draper, berlin, to face with russia's war against due to grace's military alliance spaces, new threats, would it really close ranks?

if it were a top european security basically depends to 90 percent on the us out to the hotel commentary. serious thoughts. april full on d w. the here at the munich security conference has plenty of security. i'm conflict to worry the politicians the next. but. so how's the world reach that dangerous inflection point? my guess this week has back age of experience with the highest political levels in the us. she's california congress, woman and former speaker of the house of representatives, nancy pelosi and gaza. the us as one that israel has killed 5 to many palestinians, but is jerusalem listening. how well funding for you crane clear the kind of block in the us congress and this president 5.
