world go to school. ah, we ask why? and because education makes the world more just make up your own life. d. w. made for mines. ah ah, ah, welcome to global 3000 temples without tourists with covey restrictions, now lifted. many in cambodia, a desperate for visitors to return the big eats. insects a being used to fight invasive comes in south africa and nuclear testing in the u. s. radiation victims of fighting for compensation,

blue nuclear weapons, and one of humanity's most lethal inventions. 200000 people died instantly, following the atomic bombs dropped on hiroshima and nagasaki. in august 1945, many more lost their lives due to radiation over the following years. 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 tight nuclear weapons on deadly, as shown in this report from the u. s. grandpas story told, and newspaper clippings bill reynolds is collecting them in an album with his grandson in and daughter in law misty field. he's been putting it off a long time. now time is pressingly, fast bill has terminal cancer. doctors give him only a few months. when i pass on, instead of the arabic ish, my kids and grandkids lawyers have ashley know about grandpa on

this is they don't really understand it now they're too too young to understand. it is like a lot of things. it don't mean a lot to him. right. now that may be some time when will bill is a so called down winder, a victim of his own government's nuclear testing, and the 19 fifties and 19 sixty's back when he was a child. the radioactive fallout traveled for hundreds of miles even coming down in his idaho town. he was unaware of it until he was 1st diagnosed with cancer. he says, well, you are exposed to an atomic blast. and i said, what do you mean exposed to an atomic blast? i said, i've never been anywhere around anything like that. and he says, you're down winder and asked 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 47.

bill has been battling cancer for more than 10 years now. his retirement savings have long since been to pleaded 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. but the u. s. government debt made it more than 1000 atomic bombs in the 19 fifties and 19 sixty's. most of them here in the nevada desert. often the wind blew north away from las vegas and the metropolises of california tort sparsely populated areas to the north and with it builds home in

idaho bills. parents and other adults sometimes even climb the surrounding mountains to admire the mushroom cloud. you see right there where that tower is limited. there they go up there they go up on top of that set and have a probably sitting at a beard watching open. watch that 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 what that did to 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 practice in chicago for 5 years and i saw maybe 2 thyroid cancers and 5 years and 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 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. so 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. what you should have because others music i understand having because others have a you know, fighting bag. um, but i think overall they shouldn't 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

. ready 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 win his war 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 it?

who calls this place home? some of its residents, we already know. but many of the 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 are 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 that'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 in indonesia, there are an estimated $14000.00 de rang at 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 learned 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,

about 15 percent of the world's land area is protected. this has, among other things, helped to save elephants. the 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. but move, 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 problematic debase,

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. combat the plant has been difficult despite intense research. high is one of the world's morris to am problematic. aquatic leads. it's been presence. 8 on how to base madame since the 1970s. and it's a massive problem. and they've tried to remove it manually through herbicide applications. but it's still a massive problem. 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 hyacinths natural enemies. and they've made a big find that's only 4 millimeters in size. the income it 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 pests 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

. so remitted that in this facility by testing these candidates and sit on various plants species including native species and cropped plants. and we need to do this testing to make sure that the insects that we released 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't 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 scroll, the better it is for their little enemy. they can multiply here quickly.

o approach with releasing the plans up 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 up quickie. and that also just allows them to damage the. * ponds as soon as possible, so that the plans die and expand their growth over the damn water hyacinth 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 an economic one too many people at the damn live from tourism. each year columns of workers remove 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 . hyacinth 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 decomposed 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 to where we did frequence inundate of releases of the plans hopper. and we know they're here in high numbers because they dump around as i pick up of plans. and what they damage looked like is they caused the leaves to become brown. the leaves also, i'm recall on themselves. 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 dam 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 come back has yet to happen. and those whose livelihood depends on tourism

are becoming increasingly alarmed. the towers of uncle, what are mysterious and breathtaking, but they're also nearly deserted when it feels lonely to tour guide san san to before the pandemic. he guided groups of visitors around the landmark almost every morning. and even though tourists are allowed back into cambodia now, san saw him still looks lost in the centuries old sandstone temples. they lived to depend tourism industry. them makes income daily of from tourism yet. so when, when nobody come and people lose a job. yes. so that is the, the bad consequences, tourists currently have a lot of space among the stone figures. saw and 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 feared that may be in some time be below ali job yet, but up to now the stay, it needs to be in a good security of i'll a job that we can go on a bit of a conservation here. we feel very happy with this yet. when we drive to downtown cemetery. everyone here lived from tourism in some way says san swarm. each

year, before the pandemic around 3000000 tourists came pub street was a party mile full of night life. run now. it's only a shadow of its former self is popular for 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 people tell have been pills. this one is closed? ah, so i is still close. yeah. because nobody's ever. when still close, it would be more than 3 or $300.00 something. hotel,

stay 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. so 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 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 are masters m 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, let, if it's thought tough sometime my walk from there at the road where i leave them because they can drive most motos to get in today. close it upon i want 5 kilometers. get to the fonts. yeah. sometimes so exhausted, send, but if no choice, because we've, we need to do this. first of i oh, yeah, 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 that to the bank to lead by the need to say what the, what and can yet like 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
