with different languages we fight for different things that's fine but we all stick up for freedom freedom of speech and freedom of press. given freedom of choice global news that matters w made for minds. here today into tomorrow today the science show on d w. this time we had 2 small extra dorothea rabbit tank was released into the wild was it a success. as a job applicant you may soon find yourself being vetted by artificial intelligence brave new world. like it or not our future is definitely digital

but is it also sustainable we look for answers here on tomorrow today. the rain forest is home to a huge number of plants and animals. the species diversity is astounding. but tropical forests are under threat from logging making way for fun plantations so in indonesia the island of sumatra still has a tropical lowland forest in the book national park a team that is looking for a very special animal. we're on a mission to find dora she's here somewhere deep in the sumatran jungle. is what i just pay to a party or to steam release the orangutan into the wild equipped with a transmitter. to me dora has been in the jungle for quite

a while now so we can no longer predict where she is we have 2000 square kilometers of forest here so it takes time but then suddenly you hear a rustling in the trees. of hundreds if you go through in the end doris curiosity gets the better of her and she appears. she's now 80 years old. 3 years ago she was released into the wild. but before that she'd been told all she needed to know to survive in the jungle how to climb how to build a nest and how to find food. these are things baby orangutans normally learn from their mothers but dora was an orphan she'd spent most of her life being kept illegally as a pet. as

a result she's very tame even after 3 years in the wild she readily takes to humans . the conservationists are keeping a close eye on dora right now they're worried because she appears to be losing weight. so you think if i love this. because. i don't i will. is calling. the well also but. smart. in the. pater priority has been working with orangutans for 17 years he and his team have released 170 into the wild so far. but

they'll need twice that number to produce a population that can survive on its own. our main aim is to protect lowland rainforest the orangutan is like our poster child the ambassador of the rainforest if you will and if we don't protect it we'll lose the. 80 percent of sumatra as rain forest has disappeared over the last 50 years that means the iranian towns natural habitat is disappearing none of them could survive in an oil palm or acacia plantation these monocultures are completely different from their natural habitat that's why it's so important that we preserve the remaining 20 percent of the rainforest. the focus now is on preserving the protected areas that already exist. it's too late for anything else. has also

found a new home in the book it to go pull national park where she's now living in the wild. all the orangutans in this nature reserve were born in captivity each one with its own story. for him bonnie has lived in the wild for years right now she's coming back to the center regularly to show off her young son raja. when you observe an orangutan you often see behaviors that are typical of human beings you can really see that we're closely related. each animal is an individual with a different face a different character and a different speed at which they learn new things they're like one big family.

veterinarian and honey how tante is going to check dora over. so not only has she been losing weight she's also been having difficulties climbing . probably because she was in a fight with another orangutan and is injured. and . probably. yes. the name of this national park. means. it's. just remaining forests and

one of the last remaining centuries for orangutans. survive here than tigers all the other animals will be automatically protected to you that's why it's so important to preserve what we have here. continue to observe. a release into the wild for at least 2 years the project will be considered a success if the animals have offspring. our hope is that the population here will become so large that survive on their own and reproduce so that there will be a new population. long term. perhaps when she's a few years old or. have a baby to show. helping to ensure that the orangutan population in some continues

to grow. but the problem is that for decades the rain forest in sumatra has been shrinking dramatically that is caused temperatures in the region to climb as an international research study has established what effects this will have. to fellow is unclear so. let's stay with our closest relatives for a moment how intelligent. that is thrust of many scientific investigations around the world. one finding is that 80 as well on intelligence tests as a young human children. but what is intelligence really. this is curt and this is cute curtain canuto are the same age and equally

intelligent. they inherited their intelligence it's in their genes researchers have already discovered more than $1000.00 genes involved in intelligence and they believe there are many more so well curtain can develop in similar ways in school at work and in life generally. when they're 3 years old curtin to take an i.q. test for toddlers does better than kurt why. parents spend a lot of time playing and speaking with them that nurtures logical thinking and spatial awareness. currents parents would rather spend time with their smartphones so he often has to play by himself. at this age knute is smarter genes only provide a foundation they need experiences in the real world to develop. a study of twins looked at the ratio in which genes nature and environment nurture influence a person's intelligence i q's and twins are more similar than they are between

other siblings but when twins grow up in different environments the similarities between them also fade that reveals how much environment can affect intelligence. on an i.q. test of age 10 current has. overtaking knute because in court school the children are given more individual attention. on the other hand has to follow a rigid learning plan one that doesn't pay much attention to the interests and abilities of each child environment can also hinder the development of intelligence . by the time they start to think about a profession curtain knute are once again more strongly influenced by predisposition as you grow older genes play more of a role overall intelligence. at 50 both are established in their careers as a doctor and newt is a carpenter. they each followed a very different path in life but how much was determined by nature and how much by

nurture. one could. have various professions chances are they each had a conventional job interview but moves are afoot to transform the recruitment process particularly in larger companies. in future artificial intelligence may play a major role in selecting a candidate. a company looking for customer consultants office video interview the applicants. my name is i am passionate about individuals and people the questions are pretty recorded and applicants get to answer from the comfort of their own home what's unusual is the selection process a software program analyzes the voice on the applicants face the movement of the eyebrows the smile the data is then assessed using algorithms to decide who's best suited to the job. in the course of about

a 20 or 30 minute interview we can collect 100000 data points about your vote voice the vocabulary you share internation and your facial expressions and correlate all of that to success in the job. high if you. it's a u.s. startup thanks to new char that specialized in video interviewing technology the program they offer is fed with the data of various people you've been successful in a particular job the system is specifically designed for large corporations that often get thousands of job applications so the machine is really good at figuring out what. what type of person is going to be great for this job to find out more we've come to massachusetts institute of technology or mit the elite university is considered one of the birthplaces of artificial intelligence it's a i live or a tree is constantly working on new ways of looking line the technology that she directed daniela also believes ai could be helpful in recruitment. artificial

intelligence can look at many more candidates than humans do and artificial intelligence can compare those candidates across many more different axes then people do with artificial intelligence we can also the bias the process of recruiting so there are many ways in which ai can help its workers but not everyone is applauding mathematician and data scientist kathy o'neill is convinced an increasing number of institutions are placing too much faith in algorithms. they think algorithms are objective and true and scientific that's a marketing trick were being scored with secret formulas that we don't understand. the joke that often don't have systems of appeal. a lot can go wrong when we put blind faith. in big data. she says artificial intelligence turns biased

into written code so if a company has mainly employed middle aged white men and not many women or people of color the algorithm will automatically decide in the same way we put but. we want to make sure that that doesn't replicate itself in the interviewing process she would do a lot of testing and a lot of statistical analysis to make sure that isn't the case if we do see it we eliminate those characteristics from the model as well. so what does the future hold ai experts say they don't expect robots to be taking over recruitment any time soon they emphasize that artificial intelligence is merely designed to assist personnel managers in choosing new employees. a very powerful tool but it's not going to solve all of our problems just like it's not going to take down the world the important thing is to figure out. the match between where the technology needs and what the technology is capable off so my name is like part

of you has yet to make any money with its facial analysis and it's still unclear whether such technology will ever become mainstream but we may have to accept that artificial intelligence could soon play a greater role in the job market. we are still on facebook what you think is being interviewed by robots powered but artificial intelligence. general for entering or says that ai could be great at this time even hopes that someday he will be interviewed by artificial intelligence. so well i could hear tex an equally positive view he says it would make the selection process more rational based on logic rather than emotional preferences but charles is totally against an ai interviewer which he says is. ultimately man made he doesn't like the idea of being interviewed by what he calls a filthy robot. also takes

a critical view warning that ai is just a machine that can be hacked or interfered with. andromeda says that if the ai interviewer has an internet connection he try to get it to be his friend head of the interview. when we say artificial intelligence we often think of robots if they also be accepted by us humans in our everyday lives they'll have to learn about our habits. robot ever learn to you will. know rodriguez from columbia sent in a question about not in robots but in living creatures. all animals you are and why worry you look wide open jaws.

were taken breath then exhale slowly for an average of 6 seconds it could be due to fatigue. boredom. may be a way of dealing with painful emotions or equalizing pressure in the inner ear theories abound but it's still not clear why we yawn. nor why other animals your appeasement of threatening gesture there are lots of reasons and do animals well most mammals many of them can be seen doing it except giraffes whether in the wild or in zoos no one has ever seen your supposedly or have you please write and tell us. not only mammals. other vertebrates. reptiles do too that's been definitively proven. and so has the fact that your

meaning is contagious it's a matter of empathy you can have a social function and some scientists claim that the juror. is connected with intelligence the more nerve cells in that cerebral cortex the greater the length of it's your so primates are especially intelligent. if outlet is red white auburn but on the videotape. do you have a science question that you've always wanted answered we're happy to help out send it to us as a video text over smell if we answer it on the show we'll send you a little surprise as a thank you can i just ask. you find as i did on the dot com slash science paul drop us a line at g.w. underscores site tech on facebook d w dot science.

what's the total amount of resources on the earth and how much do we use that is expressed in the ecological footprint with which a research organization keeps a count of productive service areas around the globe what is the cost to produce food and clothing or dispose of waste or generate power. the countries shown here in green use fewer resources than they have the red countries have an ecological deficit or overshoot the united states for example acts as if it had 5 at its disposal on average the world's population is currently using up the resources of $1.00 so we need more sustainability and that is difficult even in a digitalized world. back in the analog arrow we talked about the impending advent of the paper. office. we believe that telecommuting would let us

soon all work from home making the world a greener place and computers have brought environmental benefits haven't they we no longer have to crumple up a sheet of paper after typing that something right. there are other digital age developments the internet now allows us to stream all kinds of content. even our cars are linked to the net but is that all help us to be more sustainable. at the institute for ecological economy research in berlin to learn from terry assist trying to find out how green digitalisation really is. many people believe digitalisation automatically reconciles environment and economics leads to savings if you think about how many devices a smart phone can replace it seems great like it should definitely lead to a reduction in resources but it's not that simple to him money factor and

distribution of the digital devices the infrastructure cables data centers and so on also eat up a huge amount of energy. with his interdisciplinary research group it's ontario's has for the 1st time modeled an eco balance sheet for digitalisation. his results are surprising. just one example the internet is a huge energy goes a lot it accounts for 8 percent of all german electricity use that's a lot of internet. so it's a significant factor. if the internet was a country it would be 3rd in terms of power consumption globally after china in the u.s. . smartphone obsession is a common condition nowadays. even here more energy is being used than you might think. constantly use computing and storage

capacity in the cloud when i enter vices open up a 3rd of the total power consumption is on the small phones of men 3rd suppose for the provision and transfer of data to the smart phone ins because our overall power consumption and digital infrastructure is 10 times higher than in end of isis and. so is the digital way of life ruining the environment it's hard to say. to compare let's look at an analog example the book. we used to have to chop down countless trees to make the paper on which to print them. now e-books have grown common reading material has been liberated from the paper page and is now downloaded directly the trees are left standing that's good for the environment isn't it. how many resources flowing to the production of an e-book in this if you take that into account at my desk but we don't actually start saving in

environmental terms until you read 30 to 60 books depending on how thick they are. so for people who are casual readers it isn't worth it. let's look at the home cinema in the old days we bought video cassettes and d.v.d.'s all that stuff had to be manufactured using energy and resources with streaming that can be avoided a clear cut advantage or at least you'd think so. in the old days you drive to the video store to borrow a film now you stream it instead so you save a 3rd of the energy a big step up in efficiency since. i got advice largely because it's become so quick and easy we're now watching more films than we ever did in the past that's called the rebound effect as things grow more convenient it encourages more consumption and that is of course not good for the environment. another thing that's changing is mobility it used to be everyone had

a car and used it without thinking twice. these days you can book a car share spontaneously when you really need it but eventually city centers won't be unnecessarily clogged with private cars but we aren't there yet. also a challenge is untaxed the non-regulated caution is not yet a significant contributor to changing traffic in cities when these free floating systems are used instead of public transport they actually compete with trams and buses instead of being sensibly integrated with each other so now the convenience as. you drive into town then you get on with your various shopping errands in the old fashioned way before driving home again. if we all stopped doing that and everyone with a good digital citizen shopped online that would surely bring environmental

advantages. it's not as if we get all our goods sent to was bundled up in one single package but it's another issue is that every aid package is returned so if it's clothes every 2nd package so that's not so good for the environment so i've had a loss you get the shot from the comfort of your own home at all times of the day or night that means people are now inclined to buy more goods. so what to do how can we deliver on the promise of sustainable digitalisation. the bottom the tons from what we need politicians to commit to transformative digitalisation in a way that contributes to sustainability of how to cut us that. so it's time for a coherent sustainable strategy the truly paperless office for example is still largely a dream. but we've made some progress at least the typewriters been retired but.
