she like to keep taking on the powers that be they risk everything, john dunbar, miss activists, journalists and politicians living in exile. they will in torture. they live for their mission. what drives them? people need to know what is happening. there are series guardians of truth. watch now on youtube, d. w documentary. ah, 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. according to estimates by slippery the international peace research institute, there are about 12700 nuclear warheads in the world. russia has the most, followed by the u. s. and then after a gap, china and a few other countries,

russia 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 china cars, 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. he doesn't. it wasn't easy for me to talk of him, 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 for 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 engulfed him, a cloud of dust like she was back then after the blast of my head. 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 treasure co 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, tuck enough that there were more around this area because there used to be a river here, little more the lives decal below sucker, unappealing. oh, south romana a, crouched down and died. mcclockey, cynical, and cargo. so to know the growth 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. unless good, 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 hold on a 2nd. 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 you 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 can come with us in the horror of the atom bomb could go me talk to the whole world about that it has to do with there's

a monument in hiroshima as peace memorial park. but more must be done to keep the memory alive for a new generation before the g 74 meets, and 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 the disconnect. oh, i thought 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 should laugh 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, i should visit hiroshima as should all heads of state. this is the children's memorial, and hiroshi must piece part. 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 is when they and 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, cuz i didn't know, did i won't be able to tell my story much longer zip code 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 plan. it's 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 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 state white. used 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 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, 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 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 get in the toilet. 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, the store has been removed. a biological cleaning process begins. it's called primary treatment. the primary affluent comes in this way and it eaves these, these basins 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 apps, basically the transformation of the removing the ammonia out of the system. these are domes made out of allied raw material with fine pores through which air is pumped into the the massages, like fine bubbles. they can have this bubble that way. they can be making the

absorb, the more readily. they don't have to work this hard. so he want to make a good environment for the bugs that carry the survive. you want to keep happening right? 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 sell our right. and so what happens when they go into this pop? while they wake up?

and when they wait there, they want, he. right? that's what i tell him. so they go on there, 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 consists of macro filtration, reverse osmosis, and it advance oxidation process. during the micro filtration, the water is pumped at a high pressure group, semi permeable membranes. this removes 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 advanced oxidation process. in this step, u, v. light and also sodium. hypo chloride are used to create hydroxyl radicals, that destroy any remaining constituents of emerging concern and pharmaceuticals. by the end of 2024, this plant will be utilizing a 100 percent of the waste water. other plans throughout the city of los angeles. we need 10 more years until 2035 to reach that goal. after less than 40 hours of treatment, sewage is recycled into safe drinking water. just thinking back what i saw a couple of hours ago. and didn't look like at all or algebra. flight

to germany is nor the neighbor denmark top to last year's global climate protection rankings. partly, thanks to it. some business 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 the 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, whether 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 ways and are reviving their struggling economy by becoming more sustainable. but they are running into a lot of all to familiar found in public 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 re if 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 barley, 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 up that 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 started making the category. i want to start this sir. several years ago. it was a not a fight, but i was there was something quite up. he was not angry but you know, why was that? but now, you know, with the mickey scott sense that they are supposed to show off the waist and we tell them a lot that it's not waste its resources looking beautiful. so many businesses on bonham and also recycled 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 rapes either will because this directly from the from are you still have a little bit in 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 and bonham and of course also wind turbines on some of the solar panels were developed, especially for bon home like lees, windowpane ones. many businesses send their organic ways 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 are. and of course, this is a discussion always when you put on wind turbines to live, you can really see them. many islanders were against windmills in their back yard.

therefore, our local politician actually said, well, our food is not to put up more wind troubles on shore. we will put off shore on there. sadly enough, when the wind power bonham's 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 stops shining, the energy produced in peak times needs to be stored for when none is generated. we're going to pull of a massive energy storage capacity here on low, consult. 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 that few, 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 hark switch to make if you're not the richest of regions. once more of them on

the streets, their own 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 thursday in the entire island is super green and the super eco friendly politics,

dawning technologies and missing fund can get in the way and delay progress. 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 sheet a 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. with this we call 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. a is. my dad is a lighting designer, and my mom is a professor of filmmaking. the next youngest in comes test. if we were in 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, april 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 in stood. 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, you know what other people you open it, it's been pretty relax, you looks good on this pro. lemme for a while. it's been him sucked blood movie 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. and the gender based violence is one of the worst rob ansolaski. but let's put it this way. one of the worst things with the greatest effect in general is disinformation you missed ok must affect the ancient little. is love is before with going on with him. fully rip. 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.

well, we'll start all over the last year. 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 i learned in thornton cancel the funding in and that's all from us at global 3000 this week. thanks for joining us. right to us at global 3000 at d, w dot com and visit us on face that to see you next time. take care ah, ah, [000:00:00;00]
