downloads to come back to you from super. to do. our very courses put into active exercises are available at d.f.w. dot com slash dot to land on facebook in the app store. learn german for free with devon you. hear today into tomorrow today the science show on d w. this time we had 2 small extra dorothea rag tag was released into the bombs 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 farm plantations . in indonesia the island of sumatra still has a tropical low land forest in the book pollution national park a team there is looking for a very special animal. we're on a mission to find dora she's here somewhere deep in the sumatran jungle. as want to just create a party or to steam release the orangutan into the wild equipped with a transmitter. 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. the fields 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 . but. the conservationists are keeping a close eye on dora right now they're worried because she appears to be losing weight. so very few things. i love. because. i don't know will. is calling. interact with. the well also but. smart. in the jungle. 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 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 . family has also found

a new home in the book it to go 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. rim bunny has lived in the wild for years right now she is 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 . if you are a problem. yes . this national park. means for the hills. and

one of the last remaining sanctuaries 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 only 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 dora and have. is unclear so. let's stay with our closest relatives for a moment how intelligent 8 that is the thrust of many scientific investigations around the world. one finding is that apes do as well on intelligence tests as young human children. but what is intelligence really. this is curt and this is cute curtain canuto at 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 kirk 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 look 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 overt. because in current school the children are given more individual attention. klute 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 in overall intelligence at 50 both are established in their careers court as a doctor and commute is a carpenter. they each followed a very different path in life but how much was determined by nature and how much by

nurture. when caught and entered their 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. got. my name as 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 applicant's 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 use your internation and your facial expressions and correlate all of that to success in a job. is a u.s. startup based in utah that specialized in video interviewing technology the program they offer is fed with the data of various people who'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. to find out more. institute of technology or mit the elite university is considered one of the birthplaces of artificial intelligence. constantly working on new ways of applying technology she directed anjana 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 than people do with artificial intelligence we can also be biased the process of recruiting so there are many ways in which a i can help. 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 are groomes are objective and true and scientific that's a marketing trick were being scored with secret formula is 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 employees 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 interview 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 manages in choosing new employees and i is a very powerful tool but it's not going the 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. part of you has yet to make any money with its functional 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 ask you on facebook what you think is being interviewed by robots powered but artificial intelligence. general for entering says that ai could be great at this time even hopes that someday he will be interviewed by artificial intelligence. she well could hear takes 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. hectic or stand by niggers also takes

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

take a deep 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 yorn 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 a giraffe your supposedly or have you been plays right until us. not only memel as your other vertebrates such as reptiles do too that's been definitively proven. and so has the fact that your name is contagious it's

a matter of empathy your name can have a social function and some scientists claim that the jury. 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. well. pull it out on its red white flag and if you. do you have a science question that you've always wanted answered it we're happy to help out and send it to us as a video text over smell if we answer it on the show will send you a little surprise as a thank you can i just ask. find as i did a dot com slash science drop us a line at d. w. undisclosed site take on facebook d w dot science.

what's the total amount of resources on the earth and how much. that is expressed in the ecological footprint with which a research organization keeps a count of productive surface areas around the globe what does it 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. 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 digital world. back in the analog arrow we talked about the impending advent of the paperless office. we believe that telecommuting would let us assume 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 a typo that's 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 digitalization 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 seems great like it should definitely lead to a reduction in resources. for the manufacture and distribution of digital devices

the infrastructure cables data set. and someone also we got a huge amount of energy. with his interdisciplinary research groups 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. and constantly use computing and storage

capacity in the cloud went out and advices open up a 3rd of the total power consumption is on the small phones of. those for the provision and transfer of data to the smart phone ins because overall power consumption and digital infrastructure is 10 times higher than in n. devices 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 calm and 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. many resources flowing to the production of a leave book if you take that into account and us 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. other women who have it out 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 a fish and save. about the 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 when offered. 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. eventually city centers won't be unnecessarily clogged with private cars but we aren't there yet. we also challenge is untaxed an unregulated cautioning 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 and then the communities that. 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 stop 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 a look at another issue is that every 8th package is returned if it's clothes every 2nd package so that's not so good for the environment so i've had loss you get to shop from the comfort of your own home at all times of the day or night that means people are not inclined to buy more. so what to do how can we deliver on the promise of sustainable digitalisation. the bottle of tums from what we need politicians to commit to transformative digitalisation in a way that contributes to sustainability the high ticket 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 battle
