♪ chor: this week on "global 303000," wheadad to paradidise islaland which is also a populr destination for cruise ships. how does that work? in kenya, the outlook is bleak for many young people. but now some comic booook heros us question one of our moste! and newimportant senses.akg can we still trust our eyeyes? we all have pictures in our heads. and thecan be extmely

powerful. we process images 60,000 times more quickly than we do text. they arouse our emotions. they can move us, make us laugh, feel happy or sad. bubut images canan also be decee ---- and they cacan be manipuld now, e even movi i images can e altered ---- making it p possibo crcreate extremely authentic-looking "fake news" videos. fake trump: i've decided t to resign from the office of the president. i've decided to resign from the office of the esident. reporter: the next generation of fake news. on the left, trump's's face, bt his facialal expression and d s are actually beingng generatedy an actor. leading animation software developers like hao li are busy perfecting the technology behind such high-resolution facial mapping. this customized photo booth

utilizes 14,000 l.e.d.d. lightso create the hypyper-realiststic images. hao: here you can see cookie's screwed-up face that we just photographed. and you can see here, it's all rendered in 3-d. and what's really effective about this device is that it even shows the pores. we can zoom in here and see all the lines on his face. reporter: hao li's team of developers aren't interested in creating fake news. they're focused on creating new communication tools. their aim is to make it possible for anyone to create three-dimensional avatars for use in various applications. for instance, in the filmm industry. hao: i could generate a new video where my features are mapped onto someone else's. and of course i could also morph my face onto theirs, so i would actually look like them.

rereporter: specialized softwae eates a tetemplate, whichh cacaptures faciaial expressionn 3-d. this mask can then be mamanipulated as neeeeded. it's even possssible to use regular photos. however, there's no way to control how people may use it. hao: luckily, it hasn't been abused much to create fake news, but i have no doubt that will happen. there's already a lot of sosoftware that people are uploading to the internet, which people can use to map the face of one person onto someone else's. so the possibility already exists to generate videos of people doing things that haven't happppened in reality. repoporter: scientists in germy are e also scrutininizing the . a group of researchers from the fraunhofer institute for integratated circuits are teachg computerers to read huhuman

while technology advances open up possibilities, they also give rise to unintended developments. jens-uwe: of course, firirst ad foremost, you have to ask how these technologigies are goingo be a applied. you have to set clear boundaries and establish rules that address what is permissible ethically and legally. so yes, we give a lot of c consideration to the ethic, legal and social impact of our research. reporter: jens-uwe garbas and his team are working with programs similar to those in california. they hope to develop intelligent systems, which can detect, for example, when nursing home residents who can't speak are in pain. but other researchers demonstrate how this technology can be used for less benign purposes. by lip-syncing and superimposing their own facial expressions in real time, they're able to turn famous politicians into their puppets. with additional l voice mimickg software, you could d make it sm as if vladimir putin or donald

trump were declaring world war iii. since people tend to trust videos, that could lead to horrific consequences. if we can doctor them at will, it'll be harder to tell what's real and what's not. jens-uwe: it's important for us to research these subjects, in particular here in germany and eueurope, so we can better understand how such technologies work. this will l allow us to predit what m might be possssible ine future. if we don't, it'll be left in the hands of major corporations, like google and facebook. reporter: the potential dangers are already being acted upon. developers are devising software to detect whether videos are fake or not. hao: if videos go viral in the internet, you have to be very careful. the most important thing is that people understand what is possible now.

reporter: for better or worse, experts say that these technologiesdecade.e a part of ein the n near future we won't e able to say y that "seeing is believing."" fake trump: nobody told me it would be this difficult to be president. anchor: manipulated videos spread like wildfire on social media networks. authenticity is the currency of our time. so trust us -- and follow us -- on dw global society! ny children under 18 lose on or more parentdue to war disease, or natural disasters. according to unicef, in 2015 there were a almost 140 mimiln ororphans worldwdwide. countless iraqi children witnessed horrific events during the bibitter fighting and siegef the cicityf mosusul.

many h have been lefeft physicy and emototionally traumatized. they've lost t their parents ad are now w completely d dependen aid. reporter: mornings are the highlight of sukina mohammed's day. the children greet her with huge hugs. they're playful and happy now, but they share a sad past. these children were orphaned during the islamic state militant group's reign of terror. iraqi special forces recovered them from the rubbbble in mosu. this orphanage is now their home. here, they're safe and can express their hopes. sabah: i wanant to work at a companany. amwai: school principal. amnih: i want t to study at a university. i.s. wouldn't allow education for girls. reporter: sukina mohammed wants to give these children a chance to flourish. but the head of the orphanage says money and resources are a constant issue.

sukina: i am so sad that i can't really help them. i go to the government again and again and ask them for books and helpers. i beg them to make improvements and decisions. but nothing happens. reporter: this leaves children like adem in the lurch. the toddler was conceived when his father, an i.s. militant, raped his mother, a yazidi. women from the kurdish religious minority were systematically subjected to kidnapping and sexual assault under i.s. adem's mother has since returned to her husband and their three children, leaving adem here. sukina: his mother is yazidi. her religion forbids her to raise the children of muslims. that's why she gave her son to the orphanage -- and saved his life. reporter: ththe militants tore

apart families in mosul. shi'ite muslim children like ramira and ali were taken from their parents and given to i.s. supporters. after the city was freed, their uncle found them here at the orphanage. now he wants to raise themem. but years of braininwashing hae left their mark. faisal: they were taught what i.i.s. believes. now ali hates iraqi police and soldiers. he sings i.s. songs. its ideology h has shaped hihis thououghts. reporter: islamic state didn't just leave behind destruction in mosul. they sowed hatred in people's hearts. i.s. snipers even used children as bait. when iraqi soldiers came to rescue the children, they were ambushed. hamudi was used this way. he was dragged out of a

firefight by a dog as iraqi special forces closed in. the baby survived, but lost his arm. he's just eight months old, and no one knows what happened to his parents. sukina: most children can hold milk bottles at eight months. but he can't because he's missing an arm. he's often ill, and needs a lot of care. reporter: there are many such sad stories here at the orphanage. but at least now the children can laugh, sing -- and dream of a better future. anchor: many children and young adults around the world share that hope of a better future. in sub-saharan africa, more than 60% of the population is under 25. many of them long to have fulfilling work.

yet, more often than notththat dream remains s a dream. kenya has particularly high levels of youth unemployment -- around 20%, says the world bank. many young people move from rural areas to the cities, where they end up living in slums. elke: kikibera is the largest sm in kenyaya's capital, , nairo. for several l years, localals e lelearned portrtant life lesesso om an unlikely source -- a fr c comic bk. addresses issues relelevant to pepeople's everyryday lives, e widespspread joblessssness and unplanned prpregnancies, pecially among younger women. derrick: it't's abt governan and involving the youth. it's aboutut sexual reprproduc. ththat is, not jt t sex, but sexu r reproduction n as a who. and d also these i issues aboutt being a a young entrepepreneur, entrepepreneurship.. so it actually tackleses the mar issues that affe y youth most of the time.

but what does that mean for local wildlife? our reporter christian roman but what does that mean for travelled to cozumel to find our more about how people there are protecting their island paradise. jose: this island is my home. i'm very grateful that i get to meet so many people here -- tourists, ships' crews, people from around the world. christopher: cozumel is a great place to work as a biologist, becacause it has s so much nat, soanany species, a and they hae to be prprotected. raymymundo: i discovered thiss beauty area and the amazing world of scubaba diving. i decided toto do it as mymy .

perla: foror me, cozumelel is a ththousand yearsrs of history a rld hehetage. christian: cozumel lies on mexico's e east coast. the caribbean island is a favorite tourist destination. five million visitors come here every year. the harbor is large enough to handle seven cruise ships at any given time. when a ship's passengers disembark, it's like an invasion. jose nieto is in charge of harbor security. he's been on the island for 20 years, and witnessed how the harbor has been expanded to accommodate the giant cruise

liners. jose: tourism is essential for the e whole island. it's a source of income for everyone working here. we depend on thehe tourists. buthe tourt hoes rarelhead intthe raforest copy coveng the island's interior, half of which is a protected nature reserve. biologist christopher gonzalez wants to see the integrity of the rainforest maintained. but he's concerned the island is at a crossroads. christopher: i think this is the way cozumel used to be several years ago. but by now the truth is that the real cozumel is everything, and the tourists are part of the real cozumel now.

what we have to do now is to manage that reality, and the protected areas are part of that. christian: he'd like to see more visitors enjoying the natural wonders here -- for instance, on trekking tours, as long as they follow strict guidelines. however, most tourists usually wantnt to see the island's mai attractionon -- its s ique coral reefs. but jujust how long g they'll rn intactct is a concerern. cozumel is home to the world send largegestoral reef. morehan 500 species f fishliy extitition. it's a fragile parade e and a morehan 500 species f fishliy valuable t treasure. according toto a study by y the german corporation for atacaction -its s unue coralal res. inrnationacooperatn, the derioratioof cozum's coralreefsn around 70 million euros in income annually.

christopher: if we lose water quality, if we lose the clear of the water and we lose species, 12% of the people that come to cozumel won't come back. so we are working hahard to mae ththe people morore conscious t that. and when i say people, i mean tourists. but also the guides that go with the tourists. they're like our ambassadors. what the guides show, what is correct, the tourists will do that. chchstian: diving instructor raunundo ramez i is we awarere of that relationship. the conservation authorities know he's sticking to the rules, because he has to renew his tour guide license every year. -- two years. raymundo: el cielo nowadays is one of the most popular places in cozumel, because the water is turquoise, beautiful blue, only one and a half meters deep. and it's full of starfish.

and usually the people arrive in this place and take the starfish out of the water, take the selfie, and put it back. maybe the starfish is goining o be dead the next day. that is the lack of education. you cannot touch anything. christian: this ignorance is upseing totoaymundo. groups dowatat a te and d ves thathem stricinststruions.ll raymundo: if youonon't ctrol your buoncncy whe divivi, and you get clostoto theeef, you're going to t ththe ef -- mamaybe th yououhands, but mayb. sosomething withth your tank, s foatgoing g to be a big g damag. christian: they will bre o off andie.e. most touourists from t the shs spend only h half a day onon e island.. it's not m much time to o expere the culturure. cozumemel was a centnter of mn religious cuculture. ththe mayor hersrself is of mn
