the we may think our water supplies will last forever. but they won't lead when the rain is still slim starts march 20th on t.w. . welcome to global 3 thousands. now tourism and climate change have caused coral reefs in the dominican republic to die off could look barratry bred corals help restore them. tourism is big in cambodia too but chinese investors are the main beneficiaries locals are largely losing out. the 1st to go to a place that sees few tourists one area of south africa's cape town is in the grip

of gangs. it's been 26 years since apartheid ended and yet more than half of all south africans still live in poverty that's around 13000000 people unemployment is rife over 50 percent of young south africans a jobless with no prospects in sight some resorts to illegal activities south africa has one of the highest crime rates in the world violent crime in particular has increased steadily there over the past 10 years. the situation in cape town is especially troubling most tourists stick closely to the small bay area below table mountain the majority of locals however live in the cape flats. were out on patrol with the county guying near. the special task force comets gang crime in the poorer districts of the cape flats on the outskirts of cape town going

into the. the team drive to a building that's home to the leader of the corner glorious a notorious gallery. heavily armed officers stormed the building and turn the entire apartment upside down. they find large sums of cash 12800 south african round the equivalent of about 800 euros. that is now in steel. you understand is that you it will be an inquiry and. it's now your claim the money. the police also find drugs hidden in mailboxes outside the building they are packaged into small

bundles ready for sale. and that is what this one is about because she says this money she sells. that book is people money. for simple rules. the officers don't find any weapons but they suspect they're out on the street. more than a 1000000 people live in the cape flats. gangs have a hold on the area and the murder rate is one of the highest in the world. the army has been on patrol here since july 2900 but the death toll continues to rise. we're driving through gang territory a landscape that shaped by poverty drugs and violence there are

a few prospects for the young people growing up here many of whom join gangs at an early age. an intermediary puts is in touch with a gang we meet with a few members in lotus river what if. no one is forced to become a gangster so they say everyone is free to make their own decision so why did they become gangsters. and become a gang. well i grew up in the environment. now did i'm doing the same thing with those when i was in. the matter of fact way the 23 year old talks about murder is disturbing. if i get mad i will. go over there kill you shoot it. one must so worked.

hard and some murder are part of their lives says renee he too is just 23 years old . she's looking. out for. all of. them still. she was just the way to mono. and. it's a war but also kills innocent bystanders often children. people who happen to be in the wrong place at the wrong time. others are targeted if they thwart the gangs activities in some way. like after all andrew son our cargo. deal is apparently wanted to sell drugs outside his family's home after all tells us that her son tried to stop them one evening he said he needed to go out he left his phone at someone's house i'm wanted to pick it up. after remembers that it

was hard for him to say goodbye for suddenly the nice eyes were full of tears and he said i have to you know yet and i said please don't do it now don't go featured now the it is not ok and he said but i have to go free to my phone because i'm why did they my phone in it in the hands of somebody that i don't trust and if the in probably about 20 minutes after that some to came to say. average andrews chose not to feel better she set up a foundation in order to help others. everyone here shares the traumatic experience of having lost a son the stories are all unique but also tragically similar. to the poor showed me and also i think if you don't know what to do those in the moment.

the see. if you would still think that in the. subject. they don't think it would. do. it even if they did everything to me. that caught them in their heat and he was. so. some of the perpetrators are still at large i just hope and pray. they just as. well put all the children who's losing their lives in the cape. and i think. all the innocent all the small children babies. just as. the sun. was at this. after all andrew's world simply sit around and wait she set up

a soup kitchen funded by donations on her own money around 200 people come here every day. after all talks to the young people i'm trying to help them find a way out of the violence. we can save everyone all at once she says but maybe one after the other. in 2013 china announced its belts and road and it should save people so called the new silk road the aim is to expand trade links between asia africa and europe so far china has spent around 180000000000 euros on the project the final cost is estimated to reach about 900000000000 while the rest some concerns about china's expanding power many countries welcomed the cash injection individuals however i'm experiencing the downsides of chinese investment like in cambodia.

pung sierra and says she doesn't want to get used to what sihanoukville has become . there's been dirt trash and construction waste everywhere for 3 years. she shows us where her fruit and vegetable shop used to be. it's now a restaurant the chinese owner was willing to pay $3.00 times as much rent as her. reception is a little frosty. my shop used to be here pantelis. the new owner doesn't understand any. he uses the translation app to try and communicate with her on the screen it says that his business isn't doing that well. it makes me sad this shop with my life i earn decent money here i could even save some now everything's changed. to we're not. punks house is still here surrounded by skyscrapers cranes and building sites she now runs

a small online shop from her smartphone she gets inquiries nearly every week from chinese buyers who want her plot of land but palin wants to stay here even though she feels completely surrounded. the building side scare me. there's constant shaking and noise. and i don't think the buildings are all that sturdy one of them collapse the other day i'm. a little remains of the once tranquil port town of c.n.n. the. chinese construction companies have transformed the place into a tourist magnet with hundreds of hotels and casinos. most of the workers come from china. a chinese supermarket chain has opened a branch here their product range is tailored to the needs of the chinese workers and most of the profits here end up in the hands of the chinese.

as night falls a sea of bright lights illuminates the city. more than 60 newly built casinos lurch chinese gamblers to cambodia gambling is illegal for cambodian citizens but we still meet plenty in the city center after all these casinos need a lot of staff. cambodians run the gambling tables and serve the gas some of them have managed to profit from the huge changes in their city. so i don't want to. speaking only in terms of money on have a slightly better life now a bit more income. maybe my family will even come here to play. there by i don't like the way things have developed here but as far as the money goes it's ok. the space to see in a film has been completely transformed by the gambling industry and chinese funded construction projects. but the provincial governor maintains that this is a boon to the area. so if they don't get by then it might be hard to imagine right

now but we will soon have a modern on magnificent city we're making the city a small city right at that moment there's a blackout the grid is overloaded again but the governor carries on regardless we have everything under control he says. here on the outskirts of the city is a small settlement for 50 families the government relocated people here who are getting in the way of the smart city project before they're forced resettlement they were all living on valuable plots of land in the city center. the land was taken from them and used for hotels and casinos. like me who mall prandial it's so unfair i feel helpless these people are so powerful. it's a huge injustice. this area here is totally deserted when i can keep

a few chickens but otherwise i can't earn any money i met. her husband is a motorbike taxi driver and now has a long journey to work he usually drives chinese tourists around. he takes us along and shows us where he and his family lived for 30 years. his 6 children grew up here it was a tight knit community the houses have now been torn down. city authorities revoked his right to live on the property. but. it's heartbreaking to stand here. are don't know what is more heavily sadness or anger. i'm just speechless. i was a soldier i worked hard for this long for this country but what they're doing here . is this the facts only gallo. that for song and others like him it's a bitter pill to swallow. this

weekend label ideas we had to one of the world's most popular tourist destinations the caribbean behind visitor numbers are taking a toll on the natural environment they are reported to have shalem bag went to the dominican republic to find out what's happening above and below the water he made some worrying discoveries but also met people who are working hard to 10 things around. the world one of the only not all finally some fish but they've worked for days for this whole the fishes have been doing this job the whole lot. here off the coast of punta cana in the east of the dominican republic i . know. a lot 8 of them now and they used to make good money doing this little bit of. that maybe one.

up with my life was better before things are getting harder and harder fishing isn't the same as it used to be here business is really bad. holiday at 1st glance this looks like a decent cottage but 10 years ago it would have been twice the size. the reason lies here the entire coast of the dominican republic is lined with coral reefs around 90 percent of them to be the dying or severely damaged. the water temperature is rising because of climate change this makes the corals weaker and more vulnerable to pollution and human activity. this is how everything looks about the surface. mass tourism.

the country attracts 6 and a half 1000000 visitors every year the tourism industry consumes huge amounts of resources and takes its toll on the wildlife here. i should add it and it's over that hardly anyone knows this but about 80 percent of the typical white sands of the caribbean are actually the white skeletons of coral . and if we don't have healthy reefs and we don't have healthy corals we're in danger of lose. and all these beautiful things even the white sands beneath these and that in the very places where tourism is the main source of income i last saw him as on their bodies muscle l.s.a.t. up in that one thing that us. marine biologist samantha mascot is working to preserve the reefs. in the lab she prefers corals for experimental purposes.

that later be transferred to every. asset as we discover that a coral grows faster if it's divided up into small fragments rather than left in one big piece of a gas c s that i think that mine and my your it uses this disc like a purse the surface and the coral wraps itself around it as if it were its own skeleton and they're not going this thing with us and i know the corals can grow up to 10 centimeters a year using this method up to 4 times faster than they would in nature. the star for me is the alligator and some from them on a daily basis. it's usually several months before they're ready to be released into the sea. the lab is financed by a group of investors who are you know grange of hotels in the country german grants

also helped to fund that work. get the kick in a people matter i think then we can see which species are most resistant to higher low temperatures. or to low sunlight or to other parameters like an excess of nutrients or a camper when it's going to and. other species of coral require different breeding methods. several times a week samantha and her colleagues take a bite out to the coral gardens they planted in the open sea. they add up what i said we couldn't get the coral we're working with today it's called staghorn car and it used to be the. dominant species here. you know it's really sad when you think about it but we're transplanting coral in places that used to be covered in a. bag. with a hammer and some pliers and hand they plunge for me to spello the surface. of the corals they've planted a growing along a grid. once the tentacles

have reached 15 centimeters they can be broken off researches use them to help restore the destroyed reef. the groves of the carless precisely documented. the tentacles and literally nailed to the reef $9000.00 corals have been attached to the reefs i found about 70 percent of them have survived. it's a success for the team but they maintain that we should be acting productively rather than reactively. about 25 percent of the world's marine life depends on coral reefs . females let us that motorists out and we can restore the reef but if we don't change our mindset if we don't start using less

plastic if we don't start using detergents that contain less phosphate something than that and if we don't start recycling better. than all our work here won't make that much difference and that awful our authority on basket of. the team types to expand that work over the coming years they want to restore more reefs and extend marine protections i guess. but the continued growth of tourism will inevitably pose a challenge. as you might be. away from a to b. in many cities around the world chances are your movements are being tracked one study suggests that there are already are around 770000000 surveillance cameras in operation worldwide those in favor say cameras help lower crime rates as warned that they're slowly eroding our personal freedoms despite such concerns video

surveillance is on the rise by 2021 that could be as many as a 1000000000 such cameras installed across the globe. at this trade fair for security technology in moscow a major trend is making waves facial recognition many russian and chinese manufacturers are here. he recognized me who the digital doorman if you're verified you're in the camera scans the face and creates a biometric map that's compared to a previously compiled image at the next stand the salesman has a body kemah touch to his jacket which captures trade fair visitors without their knowledge it's something police could use to match against a database of suspects so who's using these systems says that the more they can be used in stadiums stations and other public places the more the technology is very

usefully is going allows you to filter out people at the entrance who pose a threat. but i like that shows it's under the picture there's all this information about me and 99 percent probability that i wear glasses for example. but only one percent probability that i'm happy. i'm estimated to be 30 years old devices thanks for the compliment and it says i'm a man. is my face is everywhere anyway if you ride the subway there are 20000 cameras installed so you'll definitely being filmed. if the police need to find you they could search through 20000 videos but it's much faster with this system is the best and it works in january 29000 a man walked into moscow structure called gallery and stole a painting directly off the wall he was arrested soon afterwards thanks to facial recognition but not everyone is for it papa is

a lawyer and an activist opposed to facial recognition. and they say they can find out the demi and i own are standing here and the exact location. of a square plus the time down to the 2nd at the foot of the cyclone but that's none with which we know for sure that facial recognition was involved in the arrests of activists at last year's protests in moscow really it's just like in china where only people opposed to the government arrested and believes that this surveillance video was used by the authorities for facial recognition it includes footage of her with a protest banner outside the russian parliament. was of them. well good idea yes our message to them is stop going after us without a court order and without our agreement you have no right to do that. is making use of her right to take the authorities to court. we're not permitted to film during

the 3 hour hearing although we can hear the judge's voice was. no good it's no wonder that she dismissed the case and. yeah right you're muslim but i'm not disappointed on the contrary it's reinforced my determination to fight . all the authorities admitted gathering data but the other side was nervous and got very irate. when you lose control like that you have to be hiding something that is a vital that this book is going to rise up over launched an appeal and there are other concerned citizens like her. journalist undertake a gonski wanted to find out whether the police can be trusted with facial recognition data and search the black market online on. myself access to the city spatial recognition system and got hold of

a hit list based on my face so. that list was 80 pages long and included a lot of people who look similar to him but there was no direct match with his own face some of the images were taken by cameras overbuilding entrances in russia that's becoming the norm. on security it's important everyone's worried about their safety nowadays. doesn't it bother you if the city knows everything. there is even without these cameras everyone knows everything anyway it comes to the internet. and that people could misuse this data and that gives me a bad feeling. somebody who wants to beat me up could find out when i get home and who with all who i visit i don't want. and popova are in a minority for most people in moscow it seems security is more important than personal

privacy. that's all from us that global 3000 this time we're back next week and in the meantime we'd love to hear from you right global 3000. fans check us out on facebook d w let me see you safe.
