so much different culture between here and their challenge in court if he. leaves. traditionalists think it was worth it for me to come to germany. or larcenous to work as a swimming instructor. our two children younger girls just rushed just to. watch your story take part. in for my greenstock. a warm welcomes a global three thousand. swimming with whale sharks is a thrill for tourists in the philippines but it's not so good for the big fish themselves. dangerous talks in the same german motel could that be possible we meet

the variance now fearing for their long term health. but we start in el salvador why gang violence has left many men behind bars yearning for a second chance at life. curbing immigration into the u.s. that's one of president trump's key concerns and he seeks support by describing potential whoreson arias this vision. has transformed once peaceful beautiful commuters who took bloodstains pilling feels. he's referring to m s thirteen a gang founded in los angeles by latin american immigrants thirty years ago the u.s. government had members deported back to their countries of origin like in el salvador there the gangs cornered the market some drug dealing prostitution and records hearing and donald trump fears that criminals like these. easily enter the u.s.

illegally in its struggle to get a handle on the situation el salvador's government has had thousands of gang members jailed. el salvador's prisons are full to bursting over them in a way that they're this man's nickname is. slang for vigilant he's been behind bars for ten years now after being jailed for murder at an angle jail was built to house three hundred inmates it's currently home to one thousand seven hundred twenty members of the m.s. thirty mg and murderous rapist six torsion ifs all cooped up together tattooed on their faces the name of their gang. the murders of the thirteen as my family it offers me protection and respect. some people look at us as if we were from outer space but in my eyes were quite normal we're like brothers who help each other out

. many of these men will never see the outside world again they live in their own world with its own rules. why you hear. of murder like everyone else here it's normal. not for me. salvador it is it's a traditional here. el salvador is one of the world's most dangerous countries seventy thousand gang members terrorized this tiny central american nation there are ten murders each day the state fights fire with fire. it's four thirty am in the capital san salvador the crack police unit the jag us around on the streets the situation in the capital is akin to a war zone. you cover us up front and here protect us from behind you. just a day earlier two of their colleagues were killed by gang members. we're going to

locations where police have come under fire and previous deployments. that's why we have to be prepared for anything and. the squad heads to the district of san has scinto which is controlled by the eighteen revolutionaries down the police's mission this morning is to track down gang members well to leone and his team frequently have to enter enemy territory. the state has lost its authority in all too many places. where there are neighborhoods where the walls are painted with the slogan watch listen remain silent. that's a clear message to the residents those who talk died. and today again the police meet with the wall of silence people here claim to know nothing about gang activities in the district the police need the locals help but the fear of revenge is great and there's nowhere to hide. live in fear

soon as you leave the neighborhood another going has you in its sights. the police is often accused of brutality to anyone with a tattoo often the sign of gang membership is treated as a suspect in the struggle for control both sides play hardball with. these sneakers hanging on telephone lines demarcated gangs territory the city is crisscrossed with borders many invisible if you don't respect them you could pay a very high price bus drivers live especially dangerously their routes across various gang territories making them open to extortion each gang wants its share. drive through all the zones anything can happen to you on the street. there's a lot of crime. the bodyguard serving cathelineau miranda follows him everywhere

the country's biggest bus operator refuses to follow the gangs rules he doesn't pay any protection money that makes him a target. he's already survived four attempted hits while on his company's premises . where you've been running the we have surveillance cameras everywhere and then over them. he spends twenty five thousand euros a month on security there are security cameras on his buses to each journey is monitored closely conditions like this a bad for business miranda believes that el salvador ms rid itself of its gangs if it is to have a future. i get to know that when you need to have courage to take on the gangs in el salvador we say that there's a lot of talk that few people have the backbone to really stand up to it all. before you set up a business here you have to consider the possibility of various things kidnapping

harassment extortion you're now. el salvador's gang problem as it roots in the united states in the one nine hundred eighty s. salvadorian immigrant set up criminal operations in los angeles. the u.s. deported the newly formed gangs back to el salvador. the government's only answer to the problem is putting gang members behind bars isolating them from the outside world the inmates aren't allowed visitors despite the tough conditions inside we don't witness any aggression here in charlotte in one go the prisoners sit together quietly. it's obvious that is the one giving the orders here like a proud prison governor he shows us prison activities bible studies handy crafts and painting courses with motifs depicting the stuff of dreams.

there were more than some of us have discovered talents we didn't know we had you heard some guy might suddenly realize that he can paint. eldritch or wants to see. his family again which is why he wants to demonstrate the criminals and murderers can reform he has a message for el salvador's leaders that. we have changed please recognize that we need reintegration programs and work we shouldn't be treated as if we're scum forever we're human beings too. it sounds like a chance for dialogue but both sides are unwilling to make concessions. somehow gangs and government must come up with answers if they are to stop the spiral of violence. and now to europe where drinking water is of the very highest quality at least that's

what we're told european environmental austerities have conducted widespread testing and ninety eight point five percent of all samples met e.u. standards sounds good but that doesn't mean it's on contaminated as a result of excessive fertilizing nitrate has seeped into the groundwater in germany twenty eight percent of measuring stations report elevated levels of nitrates. sewage from the chemical industry contains a whole series of toxic substances including p f o a a chemical that makes clothing waterproof that may be linked to cancer in humans. on the surface is the essence of but varia it conservative and squeaky clean but if you look closer the region is tainted by something you can't see smell or grasp. edmund has lived here his whole life he

never thought twice about drinking water from the tap it was dubbed the purest in the region but that's conviction was shattered when he had his blood tested amid a widening scandal in the district of. loot my blood has over forty three micrograms of p.f. away per liter my wife has the same thing and not a day goes by when we don't talk about p.f. i way it's depressing tens of thousands of people here in the altitude district are affected not because of the. for the past three years concerned citizens have been meeting on a regular basis to pressure the authorities to lay everything on the table they feel district administrators have done too little and too late to inform the public

on a levels in the water for fund blame our it was a shock to find out he was contaminated you know organise you know my plasma was refused when i tried to donate to a blood bank we formed this group because we were not informed about the p.f. we contamination here in the district only after putting pressure on the authorities and we achieved a certain degree of transparency. but just how dangerous is p f o a a for humans it. is technical officer for chemical safety of the w h o's european center for environment and health care for a is a persistent and by accumulating substances so we thought i was shall harmful effects for human health it's classified by international agency for search of cancer like possibly carcinogenic for human health and despite of much more studies are needed to confirm the health effects now we have evidence that high

concentration of human blots relate to this or this fire or it functions disorders and represent active health disorders. even though many citizens knew nothing about it p.f. away has been saying for decades district administrators say they didn't warn citizens sooner because the concentration was always under the guideline value district environmental protection head says there was and is no cause for alarm is a site that's team up here for. ever since the authorities were made aware of p.f.a. in the late ninety's the district administration provided extensive information and regular updates to the citizens of alcatel in the meantime carbon filtration systems have been installed so that the entire population has access to p.f.a. way free drinking water. so that i think. was produced and used that gandalf chemical complex for over four decades until two thousand and

eight p. a freeway was in the air and the plants waste water which is channeled into the river it's the chemical ultimately seeped into the region soil and groundwater the u.s. company responsible three m. has agreed to pay for activated carbon filtration systems to purify the drinking water supply for the next fifty years but this doesn't fix the contamination of the soil and groundwater we asked three m. to comment three m. commissioned a detailed soil investigation it concluded that the most significant intake of p.f. away for people in the district is through consumption of drinking water. the state office for health and food safety was unable to detect any relevant concentrations from the food chain industry and authorities are currently discussing how best to manage the soil within the district. according to that twenty eighteen study over

one hundred ninety two square kilometers around the chemical park are contaminated however it concluded that the levels represented no endangerment organic farmer and there's been more fire and his wife have four young children they all have at least ten times too much p.f. away in their blood even his animals have tested positive for the chemical many familiar. my family and i moved here eight years ago at that point we had no p.f. away in our blood now were heavily contaminated stockpile lost it. this atmosphere of all that doesn't last the all i'm shocked by just how fast our levels got so high it can't be just from the water it's from our animals and the food we grow here false well for all that and leaves middle. of all the contaminated areas in the region the levels in the edging of forest almost a severe edward peter loves this forest but now he can't even collect mushrooms

here. this start with you first here is. the forest here is part of my high market it's been contaminated by p.f. i weigh both for us and for generations to come it'll probably take centuries before it's gone because when this in the coming near the animals are contaminated you can see the mushrooms you can't see it but a part of our high mart has been badly damaged with it. coming through. edmund has lost a part of his home to peter for way he hopes he won't lose his health to it away will be officially banned throughout the e.u. as of july twenty twenty but the full scale of the problem won't become clear for decades to come. we meet teenagers from around the

wells and quite simple i. am going to cheat. i. should say i'll be able teen comes from colombia. a young reality my son caught us contrast nobleness i'm sixteen. there we were and i live in the same paper why in the department of says i'm colombia along. with my house my siblings two sisters i'm two brothers one of the boys is my twin girls are four and eleven years old and say on your feet. my twin brother is sixteen like me and my brother is eighteen.

in. the world is a wondrous place both on land and in the sea and humans are hungry for knowledge of so what's the world's biggest fish whale sharks these gentle giants can weigh up to twelve tons and the largest ever measured was fourteen meters long and while they're free to swim the seven seas a coastal town in the philippines has discovered a way to get them to stick around. just before five in the morning jose the fisherman and all slop heads toward the sea to mysterious giants of the deep waiting for him like shadows. he knows

they'll be there. they come every day as they've been doing for the past six years when the story began. to. feel that. we look after the whale sharks and make sure they get food that doesn't harm them and we depend on the whale sharks for our living. the whale sharks have changed everything in us law posthaste life and the lives of all the other villagers. but it's the creatures themselves that have experienced the real change . usually the world's largest known fish travel the oceans in search of crystal. clear. every day after morning prayers here in the southern philippines something happens that nature never planned for. in the past the fishermen view the whale sharks as rivals that depleted their already slim catch whale sharks were also hunted for customers in china. i don't know but it became let you know

they were only interested in their fence they said they can sell shark fans at a high price but we don't do that it's for a good shot when the sharks get untangled in our nuts we free them. we are in a lot of money thanks to the. tourists come to see the sharks and we live all down . for the whale sharks it must seem like a feast one hundred kilos of crilly day more if necessary salmon eventually move on but there are always one or two cruising about sucking up what the fisherman toss in their direction from dawn to noon. no none. in the past we were told that we weren't allowed to feed the whale sharks. but why shouldn't it be a law that we look after them and the cruel that we give them doesn't contain anything toxic we'd have given them poisoned they wouldn't have returned. and then

the hordes of tourists wouldn't have come either hunted elsewhere in these huge fish have found devoted fans. of course there are certain rules such as the four need or safety zone but people often get far too close to the large creature. perhaps because far too many people now come to see them. that. the number of visitors has increased six fold since twenty twelve turning a flip into one of the biggest tourist attractions in the philippines i know there are a fascination exerted by these gentle giants is simply too strong to resist. it's big now and it sides stick the big peter. like it's a good thing tourism and you know i mean so i don't think it's about so i'm not

sure if they're hurt but i don't think they should be fit. for your figurative not . also that they can roam around and do. anyway late i mean by the case with. every day and the question resurfaces is this relationship between man and beast really a healthy and sustainable one. we noticed injuries fresh wounds on a well shark's fin. what might have caused that. we show the images to marine biologist. he's been researching whale sharks for years and wants to ensure their survival. has to be a feller. i don't i don't specially look how clean cut is that's not something knowing audie or in a very sharp direct cut is he able to survive he might be able to survive luckily he still has to be. in there but he's definitely going to have to waste

a lot more energy than he comes to getting. for the whale shark expert it's clear that there's a connection between the feeding of these huge fish and their injuries. if a whale shark is trained up mean suit then it is not completely unreasonable to think that they could see another boat which is not one of the regular feeding boats and go after it resulting in an injury. and i was lucky everyone says that they want to protect the whale sharks but at the end of the day big business takes precedence over the welfare of the big fish. the fishing village is now bursting at the seams the boat trips alone bring an around four million euros a year. and would be anything but. i don't know young the funding but you know

what if they don't feed these well shocks. will go away again. then everything will go back to how it used to be not the. no one wants that particularly not jose who's now the proud owner of a karaoke machine he's also built a house. he's grateful to the whale sharks and for every day that they come along on monday i earn much more than i did before how about it then i earned eight euros a week. now and a second or an up to two hundred fifty baht and we only work until noon we finish at one pm. a lot of things have improved. but there's no happy ending for the whale sharks. ultimately they are the ones who will pay the price for the close encounter with humankind.

and here's what's cooking fun next week the demand for chicken is growing in ghana so it's being imported from europe and the u.s. consumers want lots of it understood cheap as possible of course for concern for local poultry farmers. that's all from global three thousand this time don't forget to write to us global three thousand and calm and check out on new facebook page d w women.
