up where 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 morning. family day at 1st glance this looks like a decent car. 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 have either died 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. amounts tourism.

the country attracts 6 and a half 1000000 visitors every year to tourism industry consumes huge amounts of resources and takes its toll on the wildlife. ironically it's destroying the things that many tourists come for in the 1st place. i should add in this a little over that hardly anyone knows the worst part about 80 percent of the typical white sands of the caribbean are actually the white skeletons of coral blanc that if the guy had not and if we don't have healthy reefs and we don't have healthy corals we're in danger of losing all these pitiful things even the white sands beneath and that in the very places where tourism is the main source of income i last saw him as on then what he had left 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 mining. uses this disc like a prosthesis and the coral wrapped itself around it as if it were its own skeleton i mean they're not going to sing with us tonight. the corals can grow up to 10 centimeters a year using this method up to 4 times faster than they would in nature. the stuff 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 lapis financed by a group of investors who are no grange of hotels in the country. german grants also

help to fund. 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 out 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 is called staghorn car and it used to be the dominant species here. so it's really sad when you think about it but we're transplanting coral in places that used to be covered in it. with a hammer and some pliers and hand they plunge 4 metres below the surface. grid . once the tentacles have reached

15 centimeters they can be broken off we said just use them to hope restore the destroyed reef. the growth of the carls is precisely documented. the tentacles are literally nailed to the remaining $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 that they maintain that we should be working per actively rather than reactively. about 25 percent of the world's marine life depends on coral reefs. thought this is the modest hour and we hammer store 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 phosphates thing than that and if we don't start recycling better. than all our work here won't make that much difference and that awful lot of our essay on bassett of. the team hopes to expand their work over the coming years they want to restore more reefs and extend marine protection science. but the continued growth of tourism will inevitably pose a challenge. as you make your way from a to b. in many cities around the world chances are your movements are being tracked one study suggests that there are already at around 770000000 surveillance cameras in operation worldwide those in favor say cameras help lower crime rates others warn that that slowly and. personal freedom despite such concerns video surveillance is

on the rise by 2021 that could be as many as a 1000000 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 as an extender 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 system at the moment it's that your they can be used in stadiums stations and other public places at the moment or technology is very useful but

a lot is you to filter out people at the entrance who pose a threat. but i like that shows it's a hero 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. and i'm estimated to be 30 years old and i think it's thanks for the compliment and it says i'm a man that what you're used to my face is everywhere anyway if you ride the subway there are 20000 cameras installed there so you'll definitely be filmed if the police need to find you they could search through 20000 videos but it's much faster with this system because 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 one of the biggest if 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 you met up with the boy at the cyclone but that's not me but if we know for sure that facial recognition was involved in the arrests of activists at last year's protests in moscow 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 this was a dumb. 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. and. it was no wonder she dismissed the case and then this but you're 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 national interest looks good allies the public are launched an appeal and there are other concerned citizens like her. journalist and baker gonski wanted to find out whether the police can be trusted with facial recognition data and search the black market online. myself access to the city's 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 over building entrances in russia that's becoming the norm. the 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's people could use use 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 out you know 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 dot com and check us out on facebook d w let me see you safe. the food.
