yes, the attacks on japan were the 1st and only use of atomic weapons during a war the international peace research institute estimates that there are around $13000.00 nuclear weapons world wide. russia owns most of them, then the u. s. and then with considerably fewer china, despite an overall reduction in nuclear warheads worldwide, the 9 nuclear powers are all upgrading their arsenals. while the strategic weapons like those dropped on japan, cause devastation and release wide ranging radiation. tactical devices, also known as many nukes, have less explosive yields, but allow full precision bombing, including on battlefields. regardless of the type nuclear weapons on deadly, as shown in this report from the u. s.

grandpas story told in newspaper clippings mill, reynolds is collecting them in an album with his grandson, ian and daughter am on misty field. he's been cutting it off a long time. now time is pressingly, fast bill has terminal cancer. doctors give him only a few months or so when i pass on and stuff that the arabic ish, my kids grandkids, lloyd hair versus know about ramp on there. cuz they don't really understand it. now they're too too young to understand. it is like a lot of things that don't mean a lot to him right now that maybe sometime will bill is a so called down winder, a victim of his own government's nuclear testing in the 1950s in 19 sixty's back when he was a child. the radioactive fallout traveled for hundreds of miles even coming down in

his idaho town. you and he was unaware of it until he was 1st diagnosed with cancer . he says, well, you're exposed to an atomic blast and i says a, what do you mean exposed to as an atomic blast? i said, i've never been anywhere around anything like that. and he says, you're down winder. and as to when i, when i start putting everything together and then i figured out my family history, then my mother lived to be the oldest of 5 children and she lived to be 40. so bill has been battling cancer for more than 10 years. now. his retirement savings have long since been depleted, spent on medications and medical bills. now he gets the most expensive drugs for free. he's never received any compensation from the government.

oh i'm, i'm mad as can be. it's the government. i mean, knowingly or unknowingly. it's the government did it. heck, regardless by the u. s. government detonated more than 1000 atomic bombs in the 1950s in 19 sixty's. most of them here in the nevada desert. often the wind blew north away from las vegas and the metropolis is of california. tort sparsely populated areas to the north and with it builds home in idaho. my bill's parents and other adults sometimes even climb the surrounding mountains to admire the mushroom cloud. as you see right there, where that tower is. there they go up. there they go. up on top of that bill certain heavily. they probably sitting at a beard lunch open. watch the the, the colors from the atomic explosion.

bills home town is in a valley in jam county. when radiation levels were measured in the late 19 ninety's . this area was the 3rd most contaminated in the united states. the fall out at that time settled on fruits, vegetables, and animals. dr. charla also sees with that did the people he's been bills oncologist ever since his 1st doctor retired. it was only a few years ago. the doctor charla moved to the area and he noticed the many cancer cases immediately. i had practiced in chicago for 5 years and i saw maybe 2 thyroid cancers and 5 years in either busy or very busy practice . and here, ah, my 1st 6 months i had 5 thyroid cancer's, which i thought was

a complete shot. pretty stable and bills case, the cancer is in his bones, blood, and prostate. among other places, the doctor can no longer cure him. he can only give him as much time as possible. a 10 hour drive further south is las vegas known for it shows and casinos, but it's also the home of the national atomic test museum visitors from all over the us come here to learn about the history of the development of the american atomic bomb. there's also an exhibition dedicated to the height that surrounded the then new technology in the 1950s. none of the visitors we speak to here are in favor of atomic bombs. but some do see their usefulness. if you don't have the capability to reduce the threat of responding, then can be taken over. so yes is a weapon that should never be used,

but you should have because others music i understand having because others have a you know, fighting bag. um, but i think overall they should be here because it's not good for anyone. bill is of the same opinion. he's already lost too many loved ones as a result of the nuclear tests. that's why it scares him when he watches the news these days. it's also why it's so important for him to tell his story until the end i want everybody to know the story because i want everybody to know how dangerous radiation is with this big conflict in the ukraine. and course, you know, i've said many times putin being away he is, you don't know if he's gonna decide days on after use a nuclear bomb in order to when is why or over there, just to say, hey, i won the war. that prospect torments bill,

especially when he thinks of his children and grandchildren, the atomic bomb, destroyed his life. it should not destroy their lives as well. forests are destroyed for farmland and soils and water are polluted and the climate is changing. nature is under pressure. every day, globally, $150.00 animal and plant species die out, scientists say we may be facing a 6th mass extinction. what can we do to stop pets? who calls this place home? some of its residents, we already know. but many other plants and animals are yet to be discovered. humans have only studied a small fraction of the estimated $8000000.00 species that exist. $1000000.00 of them are at risk of extinction. are the main reasons are disappearing,

habitats pollution, poaching and climate change. species a dying out at a rate and scale, never seen before. it's dangerous for ecosystems and therefore for us humans too. but how successful are retents to stop this mass loss of life? let's take a look at zeus some see themselves as conservationists, and many animals that live that aw, endangered species or no longer exist in the wild. a tool like push of our skis horses. they were bred in captivity and re introduced to their former home of mongolia. today's wild population of a few 100 descends from just 12 animals. and yet genetically, they are surprisingly diverse. so there's a good chance that this species will survive long time. but these success stories a few and far between animal conservationists estimate the only 20 species have

been saved by zeus. then there are rescue centers on sumatra and indonesia. there are an estimated $14000.00 durango times left at the beginning of the last century. there were about 6 times as many of the great apes have disappeared along with rain forests which have been cleared for palm oil plantations. many baby rang tangs have been captured and kept as pets in the jungle school they learn to survive in what few protected rain forests there were left. so far, nearly 200 animals have been rescued and re introduced into the wild here species can also be protected through regulation. fish numbers are decreasing in our oceans. small boats operating along coastline ins report catching far, few fish,

pollution and over fishing are the main reasons. fishing quote is are an attempt to give endangered species time to reproduce. and sustainable methods such as nets with mash large enough to spare, small of fish are intended to protect stalks around 30 percent of edible fish species are over fish and 60 percent are on the brink. one of the biggest problems here is that conservation agreements are not adequately enforced. and that leads us to the role of protected areas. to day to about 15 percent of the world's land area is protected. this has, among other things, helped to save elephants that are hunted for ivory and whose populations have been decimated. ranges here trying to protect them against poachers. other animals are also safer from human intervention in these reserves. but in some

reserves, elephants, for example, have reproduced so much that their numbers have actually become a problem. they require more food and space than there is and destroy trees, fields and even villages, or movie, there's been been a good one possible solution is to increase the size of such reserves. and in general, to foster intact ecosystems in which nature regulates itself. perhaps we humans need to learn to see nature not as something to be exploited, but as something that we are part of or oh, what do you recount? signal crayfish, and false acacia having common. they are all invasive species brought over from their original habitats into new ecosystems, either on purpose, so by accident,

through travel or trade. for example, in global ideas, we look at the havoc such invasive species can cause. this week we had to south africa where water hyacinth native to south america has developed into a green plague. but there is a remedy. a green mass where open water should be for decades. the problem out how to best put down in northern south africa has been growing exponentially. the lake is overgrown with water hyacinth, a plant from south america. now clogging bodies of water throughout africa, the invasive plant grows extremely fast. the ecological consequences are dramatic, combating the plant has been difficult despite intense research. is one of the

world's largest am problematic. aquatic leads. it's been presence. 8 on how to pittsburgh dam since the 1970s. and it's a massive problem, and they've tried to remove it manually, do herbicide applications, but it stole a massive problem am and because it can cover up to 40 percent of the damn survey. researchers in south africa have been trying to control the invasive planned for years well sealed off from the environment. scientists are looking for the water hyacinth natural enemies. and they've made a big find that's only 4 millimeters in size. the income he was water hyacinth grasshopper is also a native of south america. the insects reproduce just as rapidly as the water hyacinths. and the little guys have a big appetite in as much as is

a challenge to read miss a plant hopa. we have been successful, we keep every record of insect that is coming out of this facility. just over 10 years, we have released over a 1000000 in states. oh, in this vicinity. last year we have about over $200000.00 that we have released throughout the country. the procedure is not without its dangers. there are examples world wide of species used for this purpose becoming pest themselves. lengthy testing procedures are in place to prevent that. one of the major concerns we haven't, biological control is that in sick that me release could feed another plant species to remediate that in this facility by testing this candidate in 6 on various plants species including nature species and crop plants. and we need to do this testing to make sure that the insects that we release odd will be co host specific. this testing is very thorough and sometimes can take years. it's important for this because once an insect is released,

we can get them back. the tests for the water hyacinth locust are finally complete . the bugs are now being collected and packed for transport together with a leaf of their favorite food. they're on their way to the hot to be sport dam. rosalie smith, of the center for biological control, sees to it herself that the insects reached their destination. the denser the water hyacinth scro, the better it is for their little enemy. they can multiply here quickly. o approach with releasing the plan top is is using them as a green herbicide, sir, as many as releases as possible early in the summer. and that allows their populations to build a quickie. and that will say just allows them to damage the. * ponds as soon as possible, so that the plans try and expand their growth over the damn water high is since

form dense mats that drift across the lake. when they collide, their underwater routes become entangled and block out any light. gradually, a huge dense carpet of plans forms. they can completely over gro bay areas, which is not only an ecological problem, but in economic one too many people at the damn live from tourism. each year columns of workers removed the plants from the water with long rakes. it's a slow and laborious process that only works on smaller waters in huge areas like this though, the tiny helpers have to step in. the traces of their work can be seen on the water hyacinths leaves. holes and brown areas testify to the success of the organic pest control. the nibbled on and dead plans dropped to the ground and slowly decompose under water. you can also see them from space. within 2 years,

the growth on the dam has decreased from 40 to just 5 percent. this is a site where we did frequence inundate of releases of the plans hopper am. and we know they're here in high numbers because they down for round as i pick up of plants and wipe their damage, looked like as they caused their leaves to become brown. the leaves also, i'm recall on themselves am and so the plans in the sites is heavily damaged and that's basically what we would like for the rest of how to be as put them in the evening light. the success of the operation can be seen particularly well. swarms of grasshoppers fly over the water hyacinths. nevertheless, the plant will probably never really disappear. it spreads too quickly. even so large open water areas have re emerged on the heart of baseboard, dams,

since their introduction. this promising result could lead to the grasshoppers being used on other infested waters. empty beach is deserted, hotels, abandoned restaurants for more than 2 years. global tourism has been knocked sideways. according to the u. n. the pandemic has put around 120000000 jobs in tourism at risk. although evermore borders are reopening, the big comeback has yet to happen. and those whose livelihood depends on tourism are becoming increasingly alarmed. the towers of uncle what on the serious and breathtaking, but they're also nearly deserted when it feels lonely to tour guide san san to bang. before the pandemic, he guided groups of visitors around the landmark almost every morning. and even

though tourist are allowed back into cambodia now, tom saw him still looks lost in the center. his old samstone temples. they live to depend tourism industry. them makes income daily of from tourism. yeah. so when, when nobody come and people lose a job. yeah. so that is the, the bad consequences, tourists currently have a lot of space among the stone figures. so i saw him thinks more visitors could be lured back with special deals. but there's one noisy group right in the middle of cambodia, national monument tapping and hammering louis. so 4 and his team of restores are working to maintain uncle what for the past 25 years, the team has received funding from germany throughout the pandemic. these so called

temple doctors have continued to clean and seal the masonry at the beginning. we also feel that may be in some time v below ali job yet. but up to now the stay it needs to be in a good security of elijah that we can go on a bit of a conservation here. we feel very happy with this yet. we drive to downtown cemetery. everyone here lives from tourism in some way says san san. each year before the pandemic around 3000000 tourists came pub street was a party mile full of night life. i rush, run now. it's only a shadow of its former cell is popular before many shops. bars and hotels had to

shut their doors and this one as though they thought al, beautiful as well. so those are the rates people, then they come to stay here as all, but nobody's in there. nobody now in there. how many? how many people tell have been close this one as close as well? so i think it's still close. yeah, because nobody's ever in still close. it would be more than 3. sam ah, 300 something. hotel is still close. it's just not worth it yet. meanwhile, the government has invested millions to build dozens of new asphalt roads. cambodia is clearly setting its hopes on mass tourism sandstorm, hopes things pick up soon. this beautiful backdrop is the perfect setting for a wedding video shoot. i would here here in this

restaurant we me david p o from the local tourism association. but it's, it's not really he owns a hotel in the city alarming, but prefers to not show it to us in its current dreary state our way. but does the city really yarn for the days of mass tourism again before or you cannot really pick and choose who wants to come? the only thing you can do is manage how they come and how they live together with other markets. and yes, of course, my master's them exists everywhere. it exists in europe in venice, in paris, in berlin. and why should it not exist here? it will exist here. regardless of what happens, sandstorm throws out a fishing net. it might look idyllic, but it's not a relaxing hobby. during the pandemic,

many westerners rediscovered their love of nature. but here in cambodia, the 43 year old has to fish. if he wants to eat. that is, it's thought tough sometime my walk from there at the road where i leave them because they can drive most motos to get into the close it upon i walk 5 kilometers . get to the pants debt, sometimes so exhausted, send. but if no choice, because v v v need to do this. fuss of, i why? he bought this house before the pandemic with his work as a tourist guide and his wife's hotel job paying off alone was no problem. but now he can only find odd jobs. in addition, the prices for petrol and food have risen a lot. during the pandemic these days dinner is more often than not. a disappointment. sandstorm has to fight back his tears. when come could we

come, i'll come up. so we don't have the and all the money to pay the loan back to the bank. the lead by the need to say what the, what and can life in something like that in the situation is desperate for san san, his wife and many other cambodians. that's why they dream night after night about the tourists coming back and they're needed badly here. the sooner the better in and that ssl from us at global 3000 this week. drop us a line with your comments, global 3000 at d, w dot com and we are on facebook t d w global ideas. bye for now. take can ah,
