lies oh spits, thanks to music. ah, he was the nazi's favorite conductor is morally degenerates to musicians under the swastika, a documentary about the sounds of power, inspiring story about survival of the home and go get the cellist. i was the only one what like look, music in nazi germany. watch now on youtube. d. w documentary. ah, ah, welcome to global 3, thousands. timely reminders, the experiences of hiroshima survivors of a clear warnings in the current age of global conflict. essential and scarce

drought written, california needs innovative solutions to curve. it's drinking water shortages and the eco wise danish island of borne home wants to go. climate neutral, easier said than done. it's been nearly 80 years since atomic bombs were dropped on hiroshima and nagasaki. killing more than 200000 people in 1945 and more in the years that followed due to radiation exposure. the attacks remain the only instances of nuclear weapons used in warfare. ah, according to estimates by slippery the international peace research institute, there are about 12700 nuclear warheads in the world's russia has the most followed by the u. s. and then after a gap, china and a few other countries asha and north korea keeps threatening

to use their arsenal. while japan's last survivors tell their tails if the horace of new p her attacks are those a something to do with guests are always welcoming till she go tuckers home. in hiroshima, japan, there's some one visiting her almost every day. this 84 year old has turned her apartment into a meeting place. to day her guests are in from the u. k. ah. huddle my nedley to scott. i survived g at the bombing heater soon. it wasn't easy for me to talk up, but i'm going to tell you today when tortuga tanika tells her story,

it's not only about the suffering she experienced as a 6 year old or how her entire world was destroyed. them 2nd space or how the dead and injured filled the streets. the meeting is also about how she learned to speak about those things. she processed her misery by turning it into works of art, the school girl and gulped him a cloud of dust like she was back then after the blast hit a bit of blue sky that gave her hope. the hiroshima survivor is a popular figure. she's one of the few remaining eye witnesses. she meets up often with her friend haruki yama gucci, a 29 year old woman who wants to preserve tortuga tonic us memories. she educates her students about piece touchy co. tanaka became a 1st grader on august 6th 1945. suddenly she saw an american

airplane, then a blinding light. she was 2 kilometers away from ground, 0 and suffered terrible burns mother had those did the phone and i on the way back home. there were lots of people walking towards me with terrible burn. it's scott enough that there were more around this area because there used to be a river here, little more the lives the cold below, sucked around. if you know most of them and i crouched down and died, mcclockey cynical and call them so to know the grow that in the 2nd there were bodies everywhere. the like till she called tanika was 6 years old. when she wandered through a desert of rubble, searching for her family home, she found what was left of it. through some miracle, her mother and her siblings survived. but many of her neighbors, friends and family, were never seen or heard from again. gotcha, and asked the son telling my story, used to be too painful,

but i don't want it to be that way any more. but now i'm able to combine those feelings with hope. when she was 70, she decided to go public with her stories. her hope was that humanity would learn from the catastrophe. she 1st had to understand how important to her personal testimonial was for posterity. now she's told her story to people from many different countries around the world. and she has stayed in contact with them till she co. tanaka even has friends in ukraine nearly 80 years after the bombing of hiroshima, the threat of nuclear weapons has returned with bologna city. nicholas, we talked during a video call got you. i think i did this you. i said there's nothing i can do. did i hardly have any money and i don't have any influence coming. i happened to get my friends said yes, that there is something you can do. he gets come. it's been in the horror and the atom bomb could go me talk to the whole world about that it has to do. there is

a monument, and here she must peace memorial park. but more must be done to keep the memory alive for a new generation before the g 74 meets him. hiroshima in may, the city will host a g 7 youth forum. pushy co tanika wants to shake things up with the simple message. anyone can make a contribution to peace. the 1st step is having friends in other countries. she wants all nuclear weapons to be outlawed, but she's no politician and doesn't want to force her memory on anyone. she captivates the audience with her authentic presentation in a need. if both of you said we should make friends around well, from what i can you give us any tips on how to do that? i wanted i she left from other to me. that'd be nice and well, all you really need is human warmth. it might surprise some people,

but i've actually become friends at the grandson of president truman. he was the president who dropped the bomb. and one of the crew members of the bomber plane came to visit me at home, thought a machine on his heel. i know, lucia, she says even pooty should visit hiroshima as should all heads of state. this is the children's memorial, and hiroshi must piece park. many victims were young children just like georgia co . tanika was but stone memorials shouldn't bear the responsibility of remembering them. her rocky yamagata, she recorded trochi go tanaka accounts of her experience. now she can tell her story and enact at the locations that were bombed. done not conducting labor, but this money as i look at things in a sober fashion, a some of them all. i know have as my time on earth is very limited at this point going because i didn't know did, i won't be able to tell my story much longer so that this is one way that i can get

on. let's say they can do this. many people can no longer tell their story, so till she katana does it for them. that's her contribution to piece. wu, sir, is our planets. most valuable resource shortages can be fatal. we people, for example, can't survive more than 3 days without motor, but pollution, waste and depletion of natural resources, a causing voters scarcity. a situation made worse by climate change and population growth. to 1000000000 people worldwide have no access to clean drinking water or the u. s. state of california is partly solving it's supply problems by recycling with historically heavy snowfall and drain. since the end of last year. the outlook for california's water supply has drastically changed, but experts agree. it is far too early to consider the record breaking droughts to

be over. it would take more than a single wet year for ground water levels to substantially improve statewide. use water is still a precious resource. the challenge is to make this drinkable again, lance tuber dough isn't environmental engineer working for terminal island water reclamation planned in the los angeles area. it's part of one of the largest waste water treatment systems in the world. it's important that we make good use to recycle. the waste water in addition, are southern california doesn't want to have to rely on the other areas like the colorado and other areas where some of the water will come from. so we're trying to be independent and utilize the water that we have to it's most optimal ah level. oh, it is hard to imagine that this stinking sewage water can be treated and transformed

into a drinking water in less than 40 hours. saved drinking water is a central concern statewide. as nearly a 1000000 californians don't have access. that puts them at an increased risk of cancer, liver, and kidney problems. all mike has ruined, has been in the business since he left high school as a shift superintendent, and he walks us through the process of treating wastewater. or you start from the beginning. we have 2 main sewers that feed the treatment plan. and you're going to see the debris actually what we catch 1st. yeah. we do that. so it as an in p, the equipment down a c downstream. so we have cleaned the rough. we gotta clean up that we kinda clean those rags into debris with our upcoming sewer. anything that you flush down the toilet? anything that can go down to the sink, food waste papers,

rags you and found we were managed to begin with tori like toys come in and do you feel a fee like a break or something? yes. and, and thanksgiving we get more greece. yeah. so you're right after the course a store has been removed, a biological cleaning process begins. it's called primary treatment. the primary affluent comes in this way and it heaves these, these bases and the bacteria come here and you know, as it feeds on your galaxy command and you start, we start to work. he, she little bubbles that pop up now and then here. and when you see those little bubbles off, basically the transformation of the removing the ammonia out of the system. these are domes made out of allied rock material with fine pores through which air is pumped into the the microorganisms like fine bubbles.

they can have this level that way they can be, they can absorb the air more readily. they don't have to work this hard. so he want to make a good environment for the bugs. bacteria survive, you want to keep happening. and this because this is the heart of it, will basically taking what nature gives us. we're just making it much quicker during every shift water samples are tested to see how many solids have dropped down. some of these solids which are mainly made of bacteria, will be pumped back into the sewer to keep the biological process going. we house, we are kids compared, you know, i like to tell him that, you know, lay the bugs have done a lot of work for us. and they come in here. and basically we let them basically go to sleep. they want to go down and we're settle. all right. and so what happens when they go into this pop while they wake up?

and when they wait there, they want he fret. that's what i tell him. so they go on there. they are, they're hungry. they want to eat again so fast that so basically it's mess what's happening here. it's hard to imagine that it only took a couple of hours to change the stinky brown sewage water into this. what that mixture becomes like this. you see the clarity after more filtering and some treatment with chlorine. the water is basically good enough to be sent to rivers are used for agricultural or industrial purposes. but to make it safe to drink. a more advanced process is need it. after the conventional treatment to water receives advance treatment that consist of micro filtration, reverse osmosis and in advance oxidation process. during the micro filtration, the water is pumped at a high pressure group, semi permeable membranes. this where it moves the suspended solids in some viruses,

then the water gets pumped out in even higher pressure through the reverse osmosis membranes. and then the final step is the advance activation process. in this step, u, v. light, and also sodium. hypo chloride are used to create hydroxyl radicals, that destroy any remaining constituent of emerging concern and pharmaceuticals. by the end of 2024, this plant will be utilizing a 100 percent of the waste water. other plants throughout the city of los angeles will need 10 more years until 2035 to reach that goal. after less than 40 hours of treatment, sewage is recycled into safe drinking water. so just thinking back was, i saw a couple of hours ago. and this is how it looks like now. so i'll give it a try. ah,

perfect earth. germany's northern neighbor, denmark top to last year's global climate protection rankings. partly, thanks to it. some bishops, climate targets. denmark wants to cut it, c o, 2 emissions by 70 percent, by 2030. since early 2022. most of its electricity has come from renewables. the country sustainable future is already taking shape on the small island of porn home in the baltic sea. i know it looked like it right now, but this island might be the best island in europe and even the world. not because of its sandy beaches or its architecture or year round world weather. so cool. but because it's maybe the greenest island in the world, all the energy produced here is with the reuse

a lot of their waste and are reviving they're struggling economy by becoming more sustainable. but they're running into a lot of all to familiar, founding problems, problems that a lot of places around the world are trying to solve right now. so how did they become the greenest island? can they keep it up and what can we all learn from them? the 1st step was to rehearse waste. the common problem with islands is that waste can pile up quickly and can be expensive to ship out. many islands, especially those with lots of tourists like bali. i heavily polluted with plastic and other trash and burn a lot of it on the island. which used to be similar here to people already have to thought their household waste into fixed categories and they want to about to 12. and the waste that the recycling yard is divided into 40 categories

to make recycling easier and more efficient. powder people react basically when you're starting making more category. i wouldn't start at this sir. several years ago it was a not a fight, but our time was up for quite a while. he was not angry but you know, why was that? but now, you know, with mickey scott sense that they are supposed to show off the waist and we tell them a lot that it's not waste, it's resources looking beautiful. many businesses on bonham and also recycle their own ways so that it doesn't even have to make its way to the recycle like this fiber which is left over from producing rates either will because this directly from the from are you still have a little bit of waste leaves and stuff like that, which we are taking away also and that we are pressing into pellets. which way he

think is saving money. so no need to buy oil or gas or anything in this sustainable hotel. a lot of the furniture is made of wood that would have been thrown away shower water is we used to flush the toilet. and that doesn't mean bonham is completely waste free. some hazardous trash still gets lanfield, and about a quarter of it gets banned. the goal is to sought the waist so well that nothing has to be banned. at the latest by 2032. that when this plant will have to shut down because it will be too old, the 2nd step was to stop reducing their own energy and become less depend on electricity for elsewhere. islands especially, are often dependent on the mainland or even other countries, providing them with energy which can become expensive. up until a few decades ago, bonham's energy came from almost

a 100 percent fossil fuels. but not anymore. we have solar panels or photovoltaics . we have a bio gas system on bonham and of course also wind turbines on sure. some of the solar panels were developed, especially for bon home like lees, windowpane ones, many businesses and their organic waste to a bio gas facility where it's turned into energy. most of the remaining electricity and some of the heat on bonham is produced by burning wood chips. although wood is renewable banning it is one of the dirtiest ways of producing energy it emits a lot of c o 2. that's why bonham is planning to use less of it. another hitch was the same problem. a lot of other places have people are very, very fond of where that will live. i think we all off. and of course, this is us discussion always when you put a winter around to live, you can really see them. many islanders were against windmills in their back yard.

therefore our local politicians exit well, our factory is not to put up more winter elbows on shore. we will put off shore. i sadly enough, when for wind power, bonhams harbor is already full of offshore wind turbines, which are going to be installed a few kilometers off the coast. and on top of that, they face a well known problem. what to do when the wind stops blowing and the sun stopped shining, the energy produced in peak time needs to be stored for when none is generated. we're going to pull of a massive energy storage capacity here on molten salt. what does molten salt? it basically is salt and we will melt on putting in electricity. shoppers in electricity from the winter months when the arriving. and then we renewed, renewed energy didn't we just put water into that and creech steam. and then we produce heat and power. so therefore, we can contain a lot of energy for

a long period of time. actually, how big is it going to be? it's going to be around to the top floor. so it's going to fill out this entire room. actually, humans. it won't be nearly enough to store all the excess energy, but if all goes well, the company building it wants to install more on a bigger scale. so the original plan was to run on a 100 percent renewables by 2025. is that going to happen? do you think? definitely not. definitely not. i think would we have, i think we will be very close in terms of our energy system on, on home we have to fix land based transportation not only of on home. i think that's appropriate problem. i think that is a problem in germany or in rest and model risk world actually like with this electric charging station that in the popular as people would have hoped. the around 20 charging station scattered across bonham, which is not a lot electric cars are still more expensive than gasoline ones. meaning it's a hard switch to make if you're not the richest regions. once more of them on the

street, there on home plans to use the car batteries to also store some excess energy which is already happening on a test basis with these electric cars that are owned by the islands municipality. another big problem is this very because it runs on marine diesel and as very dirty . there's some discussion about hydrogen oil, electric engines, which are cleaner, but it's still very early days. change can be slower than wanted, especially if you can't just throw money at a problem. i strongly agree that all people want to do the right thing and the most green thing, but they have to be able to afford it also at the same time. that's why a lot of the efforts here are co funded by you or governmental programs or are set up as experiments that companies collaborate on and invest money into. so of course, all of these efforts, so, mean the entire island is super green and the super eco friendly politics. dawning

technologies and missing fund can get in the way and delay program. but there's still a lot of things we can learn from this tiny island. experimenting away on the baltic sea, you can't just copy what was done here and pasted anywhere, but you can copy the core idea, which is makes a faint ability the easiest, most logical and cheapest way of doing things. and way this isn't the case yet. we need incentives, like wrapping up factors on fossil fuels, subsidizing electric transport, or investing an experimental project like this one. a global team with this week our global teen comes from mexico with you normally, my name is ayana alcott, harry hi. so betty emu and i live in cuernavaca,

mexico, making things. and i have a younger sister. she's 14 years old and she's in high school with me for 5 is. my dad is a lighting designer. and my mom is a professor of filmmaking. the next young the scene with the free period with on the 2nd on them i will study. when i grow up, i would like to be a director actor or movie producer thought equal to the thought of a scene. ah, you have to be on the opposite of the others to yet they didn't have the opportunity to study. their education ended after high school. instead, they have to start working at an early age just to make money to be able to locate

your studying is something i now have the privilege of doing that. something i appreciate and i'm grateful to them for that. how old are you tonight? good. i saw look at your site rather before you open it, it's been pretty relax, you looks good on this program for a while. it's been instructed by mindy for that as well. you could say that the big global problems that we currently have are insecurity. lack of education, food and access to water. a gender based violence is one of the worst rob ansolaski . but let's put it this way. one of the worst things, the greatest effect in general is disinformation. enjoy me, okay. must affect the ancient little is love is before with going on with him fully red. welcome wasn't with us. well, in my free time, i really like to play basketball, him. but you could say that it's one of my favorite pastimes. i absolutely love him

without ball or loss. you're not o'connor. and i also like to do anything related to films like watch movies or work on productions. i enjoy doing anything that's connected to that other innocent thought norman candle funding in and that's all from us that global 3000 this week. thanks for joining us. right to us at global $3000.00 at d. w dot com and visit us on face that to see you next time take care i ah with

who am i when you work as an architect that go all in or not at all women in architecture. why are they so invisible to the larger public? we decided to ask them versus, what is the poetry, the secret of a house i'm house,

shattering the glass ceiling women in architecture in 15 minutes on d w. a. d w. read list. well, this week's episode is all about the power of music. we're going to go around and see what the 4th of august when it comes to hip hop and it's affiliation with politics. we are here to empower people on the monday. you tell about africa with 90 minutes on d. w. ah, a current gee, more people than ever on the move worldwide in such

a better life. one of us as well as a committed god that a lot of people actually love the noun. is it a mac or a noun? the god bagley also condense, double pay this de nanda, donation one back sitting and find out about robina story in some migraines, reliable news for migrant. wherever they may be. time, once again, we're brain update because this orchestra called the brain continuously adapts itself. and so we ask a few astute questions. we can control our thoughts, which makes us very power. kind of like a superpower. oh, questions about life?

the universe were series. 40 to be is almost everything this week on d w. ah ah, this is the w news live from berlin, high risk operations to of actuate, thousands of foreign nationals from sudan, the german military and left over 300 people from cartoon where arrival forces are fighting st. battles. millions of residents remain trapped in the capitol. also coming up, speeding up ammunition supplies to you.
