pharaohs and so it is a way of showing respect people should understand that there is an incredibly important historically and also important now because this is part of egypt's economy. here is them is in fact one of egypt's main economic sectors with the pandemic halting global movement the country is eager to draw tourists back. the message is very important what good did the people through the butt end of the month is that egypt is safe we need people to come back. these kings and queens of ancient egypt have lain in wait for thousands of years but they may have to wait a little longer before tourists flock back. and a reminder of the top story this hour. germany's president frankfurter steinmeyer makes

a rare appeal for unity in his he's certain dress he says all the nation's strength is needed to overcome 3rd wave of coping. it's. also in germany thousands of coronavirus skeptics rallied against lockdowns restrictions and supporters of the so-called lateral thinkers movement marched in the southern city of stuttgart. and we will leave you now with some what must be called exile and images of easter celebrations around europe.

as. for the. warming. douglas well yes. the industry is controlling your

thoughts the great books of the 20th century. present day hoaxes. created memories. during ignorance starts may 3rd. according to my fitness track i've already taken $2628.00 steps today and i got 7 hours of deep sleep that's about average this devise can even determine my mood seriously but is that really a good thing how healthy is self optimization autopsy today on shift. do it get enough exercise to eat the right food have i had enough water today am i

relaxed enough according to a recent survey about 33 percent of the global population has already tried out digital health trackers the market for fitness wearables has tripled since 2017 and it looks set to grow much more say experts why are we so obsessed with south improvement and is there something wrong with this not according to a psychologist you wouldn't mongst off. principle. is a part of developing further which is one of the humans fundamental needs it's part of all of us but there is a different talk about self optimisation this entails reaching optimum capacity. and this is often linked to self value and status. we try to get fitter and it's better to improve bodies but what about our. well also apps and gadgets that contract mental well being and in these times of crisis many

are starting to use such trackers but how do they work i took a closer look. no question in the world. it's also what i've been asking myself for days now i've been using delio to track my mood in the morning at midday and in the evening i can choose from 5 emotions this morning i would say that i'm good. i tell delio what i'm doing feeling and translates this data into statistics. trick is available online they are almost like digital diaries a place to record and a cavity. evaluate this information and draw conclusions about psychological health . can't really analyze he uses. a person can have so many different emotions feelings are very complex and these apps

can simplify complex matters in such a way that they might end up being not useful. delio can only track my mood when i'm using it actively it doesn't know what happens in between and that information doesn't turn up and the statistics. i don't think was that useful for me personally but it could be helpful. to record one's daily activity in order to recognize certain patterns but to do so you already have to know yourself quite well. that take other factors into account quite a bit. that i'm in the office it's time for the next test feel response can measure the sweat on the user skin this information will be linked to mood related data. i will input my mood into the app now that's a joyous because i get to see my colleagues the respond money to some biometric

data on my blood pressure for example translates them into emotional pedants recognize them when i'm joyous in the future. i don't know how precise these measurements are but on the basis of my responses to questions about concrete situations be able to propose certain mindfulness exercises there are all kinds of variables such as these on the market now some claim that they can recognize a use emotions through their voice others detect and measure brain activity all these head bands wrist bands rings measure physical data and give advice on how to improve mental health some even say that they can help people to overcome depression but you did most of has some warning words in this regard. we should remember that we should never transfer responsibility for our own life and the psychological well being of our health to a digital app it can be helpful to use them but it's very important to use them responsibly and to be aware of the risks. after work i

like to switch off and this muse had been says it can help according to the makers it uses 7 senses to detect the brain's electrical activity which it then transforms into understandable experiences so they use it to wind down and meditate if i'm not calm i will hear sounds of a storm which will remind me to concentrate on my breathing if i'm feeling calm. i will hear light summer late. i can hear some very light rain some wind. and from time to time the earth chirping that indicates that i'm really relaxed right now over. what i'm talking when it's getting heavier and the rain very real truth so i think a bit of concentrated well. i would say that a new trick is going to help people to go about their everyday life and the more mindful way but it is important to not relinquish full control and to not take them

and the exercises they prescribe too seriously i doubt that such gadgets can really have users with serious mental health issues for now people can still decide themselves whether they want to use these quantified self apps and devices but what if they didn't have a choice what if their employers ordered them to use a mood tracker. lots of work multitasking and difficult exercises this is daily life at tiny a start up based in munich the founders vision of the future is one where employees only receive as much work as they can actually carry out the idea is that software should a lot their workload automatically so that the software can do this always have to wear a device that measures the polls all the time and there's a camera that films their faces the idea is to measure their stress levels and emotional states and then their workload can be calculated. it is one of the developers he says he's not interested in surveillance or storing data but in flow

. is that this can be described as the perfect state between the feeling of being under challenge to board and the opposite which is being stressed and swamped that place in between when someone is challenged can cope with the task in hand have been used for flow. but do we really want a world in which software can. i get such a deep insight into an employee's emotional state the absolute select from the german research center for artificial intelligence things not. when they. don't want a situation in which such software leads to the surveillance of employees. with the result that someone might be fired if they don't perform adequately or if they're going through a rough patch personally and the system detects with subsequent negative consequences this has to be prevented. at this munich startup employees have to actively agree to be tracked but will this always be the case

these systems force people to share intimate information how is the data used and by whom. of course apps must collect data to quantify progress for example in health related research apple has collaborated with academics and published a variety of studies based on data collected by volunteers and their smart watches it might sound like a win win situation but i'm not so sure about giving that bunch of personal information to a private company. health ops and did his trackers collect dado when users are sleeping eating and exercising but they also gather other information for example regarding location users often have no idea what is done with their data benedict book now is a lawyer who says the terms of use are frequently formulated in a very vague way. and many companies are just connecting information and don't even know what they want to do with it but sooner or later there will be some kind of

commercial use for the data right now data is already being sold for targeted advertising to certain groups and individuals health insurance companies are also very interested in such data some of them are already offering cheaper rates to policyholders who agree to track their own health related data this is the this is great for those who are healthy it's not so great for those who are not in the end it leads to people being selected according to their risks to the super. user should think very carefully about the amount of personal information they're willing to divulge to some shops data protection is obviously a big issue but do the apps even do what they say they will all kinds of new fitness apps and gadgets flooding the market they're supposed to encourage users to exercise more without a trainer but do they really work. defense motion there's a wealth of research into the question of whether it makes a difference if

a person uses an app and tracks their activity or not and so far what it's shown is that it makes a huge difference to people's motivation many are more likely to commit themselves to their health and stick to it if they track their activity and see visible progress but it is not yet been proven that this actually makes an impact on health and whether users really do more exercise we just don't know that yet. let's listen in. addition some fitness apps can actually increase the risk of physical damage artificial intelligence and instruction videos can help people tailor physical activity to their own needs so that people are more likely to hurt themselves if they do the exercises wrongly and can't ask a real life instructor for advice. if a user wants to do something right there is a lot of work involved. will happen so it's an experience that i'm. so train is

made of flesh and blood still have an important role to play. and that doesn't just go for fitness apps even small devices can have huge drawbacks a friend of mine wanted to track all the stages obviously to optimize his sleeping pattern but he got so stressed out by the whole process that in the end he couldn't sleep at all and up might be helpful for some but not for others it's very important to find the one that's right for you this is what our expert says. is that individual or generous in is unique and not even the best dabs can map all the highly individualized elements that make a person and help them to develop an app make suggestions based on aggregated data so it can never be tailored precisely to just one individual basically no user should ever follow his gesture blindly but always ask whether it really makes sense

for them personally. however for a person in crisis any kind of support is better than none at all so even if it would make more sense to talk to a professional and out with at least give an indication of the direction somebody wants to move in and how they might want to develop so i would say use the apps but make sure you always question their advice. about. what about you have you used fitness apps and have they helped you reach your goals those on social media on d w dot com if you want to find out more about these gadgets check out our you tube channel by phone now and the.

improving the walled we all live in as well as drawing attention to the problems that i gently need solving well here are some of the topics coming up on the program. eco friendly transportation to knology made in africa an example from kenya. popcorn and why it's not just for eating as scientists in germany will be. on to the next of course of a shift in south africa is preparing young people to protect white life. but 1st a whip heads to namibia more than 20 percent of the country is on the course of asian management it is home to incredible variety over a rare and in danger of species of animal including the cheetahs the superfast cards need a very specific kind of environment to breed can't unmaintained be aborted temperature when it gets very caught the trouble is that they often live near

a rural communities and cause problems for people and their livestock now researchers hope for a way for farmers to drastically of course reduce their livestock losses without killing the beautiful big cards. a rare sight. in. the country has the largest free range in population of cheetahs in the world. but according to recent research still the numbers are little. in the population is threatened because it doesn't occur inside of national parks but on commercially used farmland there's obviously needs to conflict as the truth ok finally prey on livestock of the farms. to test population numbers across africa have dropped to less than $7000.00 worldwide as the habitat is lost to farmland and house and cost russian portion and illegal trading caps

pause a federal challenge and because to test attack livestock they also get killed by farmers. scientists from germany's like nets institute have found a way to reduce that conflict to spend more than a decade studying chicest in namibia part of their study involves putting video collis on the animals and monitor indian movements the team or not is that the cheetahs always return to 7 areas of practice passed on from one generation to the next they visit these territories and mark read in the territory so we call this centers of the territories not a marquee trees are we call the communication hops because territorial males they used these trees and also the olders into region around so these territories are very stable now always there and even if the territory hold us does

appear die then the new will territory and hold us up all day exactly the same place this allows the scientists to identify areas where cheetahs complicate the then advice to farmers not to put a live stock in those places it's about 10 percent of the area that is highly dangerous because concentrations of the cheaters is very high and about. there is much less risky for the harm was that. the firm is that i've moved out of harm's way now that was far fewer i knew most of the big cuts. this simple adjustment reduced the livestock losses by more than 80 percent and that's off the conflict for the farmers and for the cheaters in many cases.

reducing the conflict between humans and money mouse means more survive and other benefits to these powerful pre-dates has helped keep the populations of the most under control thus preserve in a mental game india calendrical balance off. what incredible creatures and what a great idea to promote a peaceful coexistence between the well and the most and the humans on this report is about a really interesting bench in south africa it aims to help communities live alongside animals in the wild as well as a professional opportunities it is called the truck a company and the name suggests it trains disadvantaged rural people in the traditional skills of wildlife trucking. the city sunny and. looking for this special friends in the dense bushland of the level of north of

johannesburg. a group of rhinos is hidden somewhere here. this is the front to pen. spurs on the ground twisted twigs and droppings lead them to the animals. their professional track has. our ancestors were doing with tracking. for meat for hunting they do it they did they try they started we were just carrying on when they offered but in a different way because then they would do we need for food we we have do we need for the for the well not to. kill or to protect will track his play a critical role in keeping the animals in the reserves safe. south africa has

nearly 80 percent of the world's rhino population and has been hardest hit by poaching but since 2014 thanks to strict security measures reserves have half dry no killings from 1200 animals to about 600 in 29000. to keep his animals safe conservation manager had money does not only rely on devices. but then we do a lot of monitoring work especially on. conservation important species like. some of the big some so on we will utilize various forms of technology to try and track these animals and keep tabs on these animals but technology fell on you from time to time. and then we have to revert back to the basic tracking skills. this is the mara reserve is part of the great career a semi desert region with characteristic wildlife vegetation soil and climate

conditions the reserve is also one of 3 training grounds for a very unusual tracker cademy today is examination day little has to show his instructors he can track an antelope in the semi arrid crew by a. different one because even when richard is in front of a big plant. a good track reads the environment and develops an intuitive feeling for the ways and habits of animals droppings are just one of many signs they read. just finally label hung by to find his target hidden in the bushes. grew up in the area that night and one on. ours see in the most annoyed this mall is the ones who and then you know what i do because the new moniker i know everything the inside out is there for someone i was getting that

motivation of i want to go to the to to learn about those in the money everything the academy is an engine that office free training to $24.00 young rural people from various african countries each year realizing that only a few traditional trackers remained in southern africa onyx when he 1st started this school 10 years ago with the help of a private sponsor meanwhile the academy gets thousands of applications pay year. because to do for the benefit of conservation and for the benefit of an ancient culture and to improve the lives of the students that come through our program think it's a new attitude and it is proving successful rain was 94 percent of all graduates are employed and the track is on needed many iconic animals like crocodiles leopards and cheetahs remain critically endangered. after a long day of working and learning in the felt the pupils returned to the boarding house will suffer for many of them heard of the tractor academy through people from

their villages who went through the program and subsequently found work in the reserves they hope that they too will one day be a role model for their peers back home. well the one who will be on the vonage boom in solar energy in 2018 accounted for 2 percent of one white and look 50 use it and its share is growing fast experts say solar and wind are said to be the most sustainable sources of renewable energy in the solomon hemisphere the international renewable energy agency says that over the past because it costs for solar have dropped by 80 percent let us now go visit an energy provider that is building the biggest solar power in germany. these panels are pretty easy to install but there are thousands of them still to go

. in the countryside near berlin germany's biggest solar park is taking shape. in modules built on metal frames. 100. posts. 250 kilometers of cable. 150 fishers working on behalf of one of germany's biggest energy companies. we definitely have the potential to complete projects of this scale but rather than size it's the viability of the project that counts for you. this solar park is the size of $225.00 soccer pitches facilities in europe tend to be smaller because they compete with agriculture for the land but solar parts alone aren't enough here in germany there are 19000000 apartment buildings and houses the

loss of roof space. and an ideal place for solar panels. on entire industry has been built around installing. now adays the systems are very affordable and economical to run since you basically don't have any maintenance costs. have become so affordable to install that they quickly pay for themselves what is your what. mugshots owns a house with a rooftop solar system in many cases the system actually produces more energy than a household needs. as one of the things that makes it financially worthwhile is that the cost of heating your house or heating your water are pretty low.

the equipment paid for itself in just a few years. after that the electricity produced is essentially free. marks fathers' energy needs do exceed what he produces though that is because his family have 2 electric cars that need to be recharged. off. solar energy is expected to see significant growth in germany. by the time the last coal fired power station is switched off and 2038 there would have to be 5 times as many rooftop solar systems and parks as there are now to cover energy needs. solar energy would then account for a quarter of the country's power i would push. back to germany biggest solar park

project 10 years ago the operating company was one of the biggest nuclear power producers in the country. still run several coal fired plants but that will soon be a thing of the past. 39 and. these new energy sources will have to fill that gap they've become a central pillar in our portfolio. should be 12 we've seen growth in all new and renewable segments including wind both offshore and onshore as well as solar. these technologies will account for about half of our output by 2025 i need. the solar panels just keep on coming day in day as. talk so sustainable mobility tend to focus on the big cities in ways to reduce

traffic congestion and pollution and of course make life better on you give me basis on protecting you and what if you get off because well it's not so good do these optical you know they since it was developed you take. these handcuffs off in a way several 100 kilos and here in kenya's capital nairobi thanks alston's noise are another problem for day laborers. kind of quantize invention could make life easier it's an electric car constant goes faster and can carry more event in the system. is it a thicker. to sylvia charge where do you wish to kill it. if you go looking at the people who know them or is it just sort of leaving it up to you

doesn't use can doesn't tell you very well we'll see if this. in addition to sparing the environment the new vehicle can live up to 7 kilometers an hour without using much man town its ability to power itself is kinetic energy at its best and a big help for users. to. buy you are working. and everything is pathetic quite then. cream to achieve this quantized utilities electric rickshaw unlike noisy diesel took to this version rolls through nairobi almost silently and without emissions it also carries 5 instead of 3 people you want to diversify that's. what they cannot and immediately be made it can be in buses while we will be able now to divert up one of their major electric more beautiful company you know. on top of that it's

produced sustainably since all components of the electric vehicles come from the region. and how about you if you're also doing your bit tell us about it this is how websites all send us a tweet. hash tag doing your best. we share your story. a little the things we notice in our day to day life i made the point of nothing and was still was you he was modelled on was for the entire exhaust fumes from the cars and from class to class you know since all climbing high. i love i just examples he's a terrible. scientists are looking for alternatives and sometimes come up with great ideas. there is a professor at mit doing. the things we've called.

this building is getting added thermal insulation and damp roofing from polystyrene for every year of the 10000000 tons of the synthetic material turned into everything from facade cladding to disposable. and packaging. but one extremely useful the downside of the material is that it is essentially non-biodegradable and takes centuries to break down and as it does it releases miniscule particles into the ground and our water supplies. this man has a plan to replace the plastic pollutant since 2008. poor and his team have been looking into an environmentally friendly alternative pop corn. similar to polystyrene foam. consists of a mass of cavities filled with their poor. can see them when you dissect

a piece of popcorn and examine it under the microscope. that's what makes it so light. like the mark the researcher and his team have already used popcorn to create kitchen furniture there showing manufacturers the range of potential applications for popcorn the 1st step is to turn it into a massive granules all the same size the original maize is grown in germany well that is land intensive on the plus side the material will help to reduce fossil fuel consumption. and you can eat or it tastes a lot like popcorn except there's no sugar or chocolate of course so the taste is a bit boring. the granules of been pressed together to form sheets or panels with plant proceeding providing the bonding agent as opposed to synthetic chemicals this makes the material compostable and even

suitable as animal fodder of the team are pioneers in the field. they also use a hot air gun to compare the thermal conductivity of polystyrene phone to that of popcorn and then measure the heat that penetrates through to the back in the case of polystyrene foam the sensor reads 28 degrees celsius while the popcorn board is even better at absorbing the heat here the reading is under $25.00 degrees. houses with the panels in the walls or on the facades also or you can also use them as insulation for solid. material also performs better in the flammability test the polystyrene burns up at a frightening speed immediately beginning to melt and release toxic gases.

subjected to the same flame the panel of popcorn barely catches fire. only reason the poor is happy to pass on the fruits of years of research on the material. or he hopes to see environmentally friendly products made from popcorn replacing polystyrene foam on a large scale and the sooner the better. the 1st popcorn packaging is due to go on the market in the fall of 2021 and will hopefully help to reduce the world's growing mountains of plastic waste. and new technologies can certainly make our lives easier when the internal combustion engine was developed in the 19th century no one in margin of the air pollution on
