♪ ananchor: this week onglobobae island which is also a popular destination for cruise ships. how does that work? in kenya, thoutlook isis bleak for many y young people. but now some comic book heroes arcoming to e rescue! and ng us question one of our most important senses. can we still trust our eyes? we all have pictures in our heads. and they can be extremely

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. but images c can also be d decee -- and they y can be manipipul. now, even movingng images can e altered d -- making it possibleo eate extremely auththentic-looking "fake new" videos. fake trump: i've decided to resign from the office of the president. i've decided to resign from the office of the president. reporter: the next generation of fake news. on the lefeft, trump's face, bt hifafacialxpressssion and wowos arare actually being generatedy an a actor. leading animation software developers like e hao li are by perfecting the technology behind such high-resolution facial mapping. this customized photo booth utilizes 14,000 l.e.d. lighttoto create t these hyper-realistic

mapping. this customizimages.o booth 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 film 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.

reporter: specialized sosoftwae creates a template, which captures facial expressisions n 3-3-d. this mask can t then be manipulated as needed. it's even possibible 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 arere uploading to the internet, which people can use t to map the fae of one person onto s someone else's. so the possibility already exists to generate videos of people doing things that haven't happened in reality. reporter: scieisists in gegermy arare alsocrututinizg the e fa. a group of researchers from the fraunhofer institute for integrgrated circuitits are teag mpututers to read d human emotions.

while technology advances open up possibilities, they also give rise to unintended developments. jens-uwe: of course, first and foremost, you have to ask how these technologies are going to be applied. you have to o set clear boundars and esestablish rules that addrs what is permissible ethically and legally. so yes, we give a lot of consideration to the ethical, 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 voice mimicking software, you could make it seem 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 europe, so we can better ununderstand how such techchnols work. this will allow us t to predit what might be possiblele in te 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 technologies will be a part of everyday life over the next decacade. in t the near future we won't e able to say that "seeieing is bebelieving." fake trurump: nobody told me t would be this difficult to be president. anchor: manipulated videos spspread like wildfire on socil media networks. authenticity is the currency of our time. so trust us -- and follow us -- on dw global society! disease,r naturadisasters.e acc0 or me papares due to war, there werere almost 140 0 miln orphans worlrldwide. countless iraqi children witnessed horrific events during the bitter fighting and sisiegef the cityty of mosu

many have been left physicalaly and ememotionally trtraumatiz. they've lost their parents and are now w completely dependentn 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 rubble in mosul. this o orphanage is now their home. here, they're safe and can express their hopes. sabah: i want to work at a company. amwai: school principal. amnih: i want 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 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: the 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 wanants to raise them. but years of brarainwashing hae left their mark. faisal: they were taught what i.s. believes. now alali hates iraqi police ad soldiers. he sings i.s. songs. its ideology has shaped his thoughts. reporter: islamic state didn't just leave behind d destructionn 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 n not, tht dream reins a a drm. 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: kibera is the largest slsm in kenya's capitalal, nairobi. for severaral years, lococals e learned impoportanlife l lesns from an unlikely source -- a eeee comicook.k. it addresses issues relevant t people's e everyday lives,s, e widedespread joblelessness and unplanned d pregnancies,s, especially among younger women derrk: i it's about gogovernane and involving the youth. it's about sexual rereproducti. that is, notot just sex, b but seal repeproctioion as wholele. ananalso these issues about beg g a younentrtrepreur, entrepreneurshipip. so it acactually tacklkles the r issueses that affectct youth mof thtimeme.

elke: they now rch well ovover six million peopople. ththeir longer-term gogoal is to increase their online presence. rob: what else can the internet acrdo to create energy anandn. popoibilities r our millions of followers soso, we have some ideas, wewee developing fast. to say, can we take ththe prome of the "shshujaaz"ffecect an deliver r it bigger, f faster, betttter, quicker,r, cheaper, oe internet? at's what we worki o on. elke: more a and more peopoplee gegetting linene in bera t too- but for the moment, the d-d-fashioned cocomic ok continues s to inspire p peoplo share their r stors and d embre new ideas. anchor: today in global ideas, we visit a small island off the coast of mexico. every year, cruise ships take millions of passengers to cozumel.

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, bebecause it hasas so much nat, so m many spies,s, andhey hahae to be e protected. raraundo: i scoveredhihis beauty aa and the amazin world of scuba ding.g. i decid d to dit as s myob.

perla: f for me, cozumumel is a thousand yeaears of historory a world heritage. christian: cozumel lies on mexico's east coast.t. 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 whole island. it's's a source of income for everyone working here. we depend on the tourists. chriian: but thtouristhordes relh rainrest canopcoveringhe isla'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 want t to see the isisland's n attractition -- its ununique cl reefs. but t just how lonong they'll rn intatact is a concncern. cozumel l home to the world's secondarargestoral r rf. more than 500 spies s fish lilive he, somome reatened by valuablele treasure. according g to a study b by the german corporation for trtraction- itits unue cororal valuablelefs.easure. ainternatiol cooperion, tby the derioratn of cozum's coralreefsd ound 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 hard to make the people more coconscious abt that. and when i say peoeople, i men 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. ristian: diving instructor ymymundo rirezez is ll awaware corrof that relationship.l do 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 going to be dead the next day. that is the lack of education. you cannot touch anything. christian: this ignorance is upsetting g to raymundo.o. that's w why he only t takes sl groups down n at a time anand s ththem strict ininstruction. raymunundo: if you d don't conl your buouoyancy while didivingd yoyou get close e to the reef, you're g going to hit t the re- maybe with your hand b but may wi the tanank. yoyoand if you hithe c caleef, formation orhehe snges orrhe re- msomething wiwith your tanknk, s goining to be a bibig damag. chchstian: they will break off andidie. most t tourists fromom the shs spend onlyly half a day y on e islandnd. it's notot much time t to expere the cultlture. cozuzumel was a cecenter of mn religiouous culture. the mayor heherself is of f mn

take more e interest in n te islaland's culturere and hist. perla: due to cozumel's uniq geogphicical lation,n,e'll never r be able to a avoid all e cruisese ships. but we shohouldn't be afafraio seset down ruleses for the touo. if you're gogoing to destrtroye enenvironment, t then you can'nt comeme. can't comeme.t patronizr and if y you don't enrnrich ouru society, t then you're n not weo here. christian: i in the eveninings,n the harbor e empes, cozuzumel becomes tranquil -- but only for a few hours. the next cruise ships will soon be dockingere again.
