back to 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 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 daiichi 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 the 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 think adam is going it 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 neverland that. and if we don't have healthy reefs and we don't have healthy corals we're in danger of losing all these beautiful things even the white sands and that in the very places where tourism is the main source of income i last saw him as on then thought he must like i said laughing that's one thing that us. marine biologist samantha mascot is working to preserve the reefs. in the lab
she prints 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 you know it uses this disc like a prosthesis and the coral wraps itself around it as if it were its own skeleton and they're not going the distance of. 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 sound 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 i know grange of hotels in the country german grants also help to fund. the picking up people matter i think then we can see which
species are most resistant to hire a mo temperatures. or to low sunlight or to other parameters like an excess of nutrients for example 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've planted in the open sea. that whatever that 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. grit . 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 corals is precisely documented. the tentacles are literally nailed to the remaining $9000.00 corals have been attached to the reef site from about 70 percent of them have survived. it's a success for the team but they maintain that we should be acting proactively rather than reactively. about 25 percent of the world's marine life depends on coral reefs . let us the motorist out and we have 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 fossil for its thing than that and if we don't start recycling better. than all our work here won't make that much difference and that off oil out of our essay on basket of course. the team hopes to expand that work over the coming years they want to restore more reefs and extend marine protections. 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 they're slowly eroding. personal freedom despite such consensus 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 through 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 systems at the moment it's that your they can be used in stadiums stations and other public places at the moment the technology is very usefully is it 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 give thanks for the compliment and it says i'm a man 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 going to the best and it works in january 29000 a man walked into moscow's tretyakov gallery and stole a painting directly off the wall he was arrested soon afterwards thanks to facial recognition but not every. as for it papa is
a lawyer and an activist opposed to facial recognition. and one of the biggest in the state 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 set up with the boy in the sequel and 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 it's just like in china where only people opposed to the government are 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 a dumb. well good idea yes our message to them is stop going after us without a court order and without our agreement me 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's no good it's no wonder that she dismissed the case and then the. 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 live it's part of our launched an appeal and there are other concerned citizens like her. journalist undertake a gun sketch 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. that list was 80 pages long and included
a lot of people who looked 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. if the security it's important everyone is 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. 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
