system referee disallowed the colts. it watching the news live from berlin coming up next the w.'s technology shift with a look at whether official intelligence can save endangered species in fact that more news of the top of the hour and now on behalf of the whole same thanks so much for joining us. from. where i come from we had to fight for a free press and was born and raised in a military dictatorship with just one to the shadow and a few newspapers with official information as a journalist i have worked on the streets of many cancers and their problems are always the same core to social inequality a lack of the freedom of the press. corruption work on the floor to stay silent

when it comes to the fans of the human scene or my through folds who have decided to put their trust in us. my name is johnny carson and part. of you stream the video today i suddenly have and that's not good for the environment but i store a lot of data in the cloud instead of by the get out so that should reduce my environmental footprint or does it just how green is our digital lifestyle today also. did you know that every google search consumes electricity zero point three you want always to be precise. that's what a sixty watt lightbulb consumes in eighteen seconds it may not sound like much but

when you consider that google processes three point five billion search requests every day it adds up so should be do without google i can't imagine it to be honest even though it would save energy the internet is too much a part of my life offline alternatives do exist of course like going to an actual store instead of ordering online or using a good old fashioned map instead of a sadness. can we make the digital revolution more sustainable we spoke with environmental economist stephan longo in his book smart green world he tries to answer the question so what really is better for the environment. renting a d.v.d. or streaming a movie generally speaking watching a d.v.d. consumes less electricity because transmitting data from the cloud of energy but if you drive to the video store that increases the environmental burden. of them one by thoughts can make you drive more than twenty kilometers streaming is better less

than a d.v.d. is better if you walk to pick it up a d.v.d. is always better to file cabinets for the cameras. the rule of thumb here is that it's best to print lest unsafe paper. before only talking about files and documents the cloud is green or a paperless office is the way to go. or. purchasing things that if you market is more environmentally friendly online shopping consumes electricity and then those transportation packaging to you both of which result in significant c o two emissions. of all the things you can do online is sensible since it's a secondhand online market. buying used is better than buying a new one amazon what sorts of calls take a book or louisiana here it depends on your own habit the more books you read on instead of in a printed version the greater the environmental benefit. is the tipping point

comes between thirty and fifty books that's when a new reader becomes greener than paper. shopping mall or online shopping a brick and mortar store is still more environmentally friendly delivering individual consciousness to your doorstep isn't energy efficient. if it were working at full capacity online shopping could be more environmentally friendly ironically though when you shop online you're. raj with advertising which makes you consume even more. she's very easy to do streaming storing files in the cloud shopping online it will take just a few clicks but the fact is even an energy efficient process if you repeat it often enough and zapping creasing energy consumption so if you still isn't automatically green. digitalisation isn't going to increase distain ability automatically. we need to transform society and the economy to make it sustainable

and then see what positive role digitalisation complaining that. digitalization doesn't always make things more environmentally friendly so it's worth thinking about which solutions are more beneficial take sharing platforms for example the sharing economy is booming nowadays we can share cars bicycle apartments you name it and that called all of your for instance lets you share food that would otherwise be thrown away anyone can use it private individuals supermarkets and restaurants it's a clever use of mobile technology what are your thoughts on this stephanie. sharing economy is a great idea. digitalisation has been good for some things food sharing sort of thing. but it's important to realize that there are also some negative examples. so . there have been several studies on car sharing and they've concluded that people

tend to use car sharing instead of walking for taking the subway. so in reality it's like a substitute for buying a car. so caution erring may actually put more cars on the street and it doesn't seem to affect the number of new cars purchased and what about our buying habits when it comes to smartphones i'm already on my tan which does make me feel a little ashamed. and i'm just one of many people who always want the latest and best in these seven billion smartphones were manufactured between two thousand and seven and two thousand and seventeen at a high cost for the environment first the other raw materials smartphones use rare earth and precious metals from cobalt and the battery to india and the touchscreen they have to be mined and chemically processed all of which is environmentally damaging. companies invest heavily in advertising to get us to buy the latest devices as a result many smart phones are replaced even though they still work that's also

true for computers t.v.'s kitchen appliances that can hardly be considered green then there's energy consumption the more complex the device the more energy goes into making it and even surfing uses much more energy than you might think. that the factories of the digital a. vast amounts of data so that users can access it whenever they want with an extreme in a film using a search engine. in. transfer. of energy. if the internet were a country it would be the world's fifth or sixth biggest energy consumer. like. currency mining is especially energy intensive minus one when bitcoins computing power to keep the network operating running that power helps to complicate complex mathematical equations to verify financial transactions. being billed to mind

it to estimated that each transaction as much energy as a refrigerator freezer uses. video streaming is also an energy hog using ready accounts for sixty percent of data traffic and energy consumption that. in germany. as are currently increasing their power consumption by six percent a year for worldwide that figure is ten percent of its affairs unless we generate this energy from renewable resources for all contributing to climate change. around the world to the number of internet users continues to increase last year it rose by nine percent. what's going to do to save energy the internet of things all i would say for short could help the i.o.c. is a system that network smart devices a washing machine say well then only run when it gets enough power from your rooftop solar installation will be io t.

help or hurt the environment let's take a look. heating and cooling a building takes a lot of energy do light. it's estimated that tough that energy is wasted intelligence on io t. systems measure energy use with smart senses and send the data to the cloud. very analyzed to see how energy might be saved. that is the internet of things continues to grow it will transmit ever more data and that too consumes energy not all of this data delusion is useful to the cloud or data center intelligent gateways can help it that data flow to pass on only what's relevant which helps save energy. these smart windows generate electricity built in so cells transform light into power which you can even use to charge your smartphone and smart sensors in the windows respond to environmental influences in

order to help keep indoor temperatures pleasant while saving energy. so not even experts assured whether the internet of things will be an environmental boon it will depend on two things how much energy of the devices consume and how much data they transmit another new technology that could benefit. if the environment is artificial intelligence could i help save endangered species years and maybe help save our forests at the earth live forum hosted by microsoft berlin a i expose and environmental pioneers whether it can boost sustainability and arrived at some fascinating results. can process huge amounts of data in a short time that allows us to tackle projects that would otherwise be impossible. ai self cannot save our planet however i can tell you that without ai we will not

get there we cannot manage what we don't measure so we need to start by measuring earth resources so that we can little by little improve how we monitor model and ultimately manage earth resources for example the wild need project identifies and tracks wildlife populations photographs of animals or uploaded onto an open source platform for researchers and private citizens in ai system identifies each animal by its markings and other features and records of the location and time the image was captured that allows scientists to monitor migration patterns for example. and lets users trace the movements of an animal they photographed on their last holiday. the sylvia terra startup wants to use it to improve forest management in the united states the software assesses forces using satellite imagery recording species of the trees their height and the density of the forest this information allows for more efficient forest management biodiversity and helps ensure the water

supply. right now scientists that are focused on conservation and are spending thousands of hours just sit through images by using artificial intelligence you save the time why did you used to take one hundred days you can take all your couple of hours. and that time is now spent back in research instead of sitting through. most systems that seek to protect the environment are still in development. how effective they'll be remains to be seen. processing all that data takes a lot of energy. for a project to be worthwhile it will have to be effective enough to offset energy consumption. has one thing you can do use a search engine that pounds trees in directly of course it says they invest eighty

percent of their ad revenue and reforestation and conservation project for every forty five searches a tree is planted it calls it is a search engine mask and the results of powered by big now about you could you imagine only going online when you really need to watching a film on d.v.d. rather than streaming it and using your smartphone until it actually gives up the ghost could changing our digital lifestyle help save the planet changes like this just a drop in the bucket compared to what's truly needed tell us what you think on facebook or on d w dot com. and see a. three
