other just so you can you know isn't useful and doesn't but you say well we'll see if this is. in addition to sparing the environment a new vehicle can move it up to 7 kilometers an hour without using much manpower its ability to power itself is kinetic energy at its best and a big help for users. imagine us this on the ground by you are working you know how everything is pathetic why then vital meant to be. cream to achieve this quantized developed his electric rickshaw unlike noisy diesel truck trucks this version rolls through nairobi almost silently and without emissions it also carries fine of instead of 3 people you want to diversify the products that utilize what they cannot and in it it can be made it can be in buses while we will be able now to develop one of their major think more beautiful company. you know we can

talk about that it's produced sustainably since components of electric vehicles come from the region. and how about you if you're also doing your bit tell us about it visit our website also send us a tweet. hash tag doing your best. we share your stories. a lot of the things we use in our day to day life on live from oil wealthy and well still you will you feel was an adult and that is but with it and it's also fields from the. plastic for us in the real sense opining. and those are just a couple of examples it is a terrible problem scientists are looking for alternatives and sometimes come up with great ideas i've heard that there is a professor at mit who was doing. much of the things we've called.

this building is getting added thermal insulation and damp roofing from polystyrene for every year over 10000000 tons of the synthetic material are turned into everything from facade cladding to disposable bowls and cups 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 and since 2008. poor and his team have been looking into an environmentally friendly alternative pop corn. similar to polystyrene foam or in one consists of a mass of cavities filled with there are no. can see them when you go the piece of

popcorn and examine it under the microscope. that's what makes it so light. like the market research and his team have already used popcorn to create kitchen furniture they're showing manufacturers the range of potential applications for popcorn the 1st step is to turn it into a massive granules all the same size as 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 salt or chop wood of course so the taste is a bit boring and. the granules have been pressed together to form sheets or panels with plum proceeding providing the bonding agent as opposed to synthetic chemicals this makes the material compostable and even

suitable as animal fodder of the team pioneers in the field. but they also use a hot air gun to compare the thermal conductivity of polystyrene foam to that of popcorn and then measure the heat that penetrates through to the back in the case of polystyrene foam the sensor reads $28.00 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. or you can also use them as insulation for solid. material also performs better in the flammability test 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 mit . 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 the air pollution on serious

health issues it will be later that his white day many you know waiters call me to finding it will be a waste pouring machine. when these innovations help to counteract climate change then wait to see for yourself. we that corn husks aren't uncommon in ground out these days the current drought has lasted months and the increasingly extreme weather threatens the libel hood's of local farmers especially those in the eastern part of the country or no quote could be attributed it's apparent that climate change is real and increasingly dangerous the farming seasons that people are used to are not longer predictable at times it trains we're one expected drought well route instead of rain and it's confusing you can just farm and have hope over having harvest and what you were initially and when you haven't been a couple to lie you is one family who has been fortunate during these hard times have filled me a roof so she's been able to pump sufficient water to her crops. but they do so you

needed to power the pumps is expensive and the exhaust that is a meter to sends out contributes to a greenhouse effect the researchers and technology experts from around and start up are developed a solar powered irrigation system that they had to project was financed by a u.s. aid organization and they run the government they knew irrigation plant came at just the right time for 40 families from authorities in the district that god made agricultural more difficult and the cost of renting the diesel pumps nearly consumed the needs. we ended up spending much of what awnings on buying fuel while using the fuel pump into narrators ira for 2 of the those little left for our livelihood now we have gotten great of all those expenses we only need to replace someone to water the

plugs. of the kurdish just. due to the more affordable. edition promised cannot attend a larger areas of land and keep farming they used a much higher a series of. i did call a hole i was only have a sting 50 kilograms of bugs osogbo it sees on wood so let irrigation the yield volume has multiplied by 3 when i am considering expanding my farming even when i'm in a focus on the solar powered irrigation system should be up and running in all of the party districts in the country by the end over $20000.00 to me this tucked up that builds the sauna irrigation system has also developed a system to michele the temperature and moisture of the site since those calculate the exact amount of water needed by the plants. farmers i've been

notified by and up about when and how much they should what corrupts the plants need to get the optimal or what's being that's what we believe when they use this technology to improve their production. and it does been tested to be a success in the play which is why been doing. these pilot system is powered by solar energy us well now the farmers know exactly which plants need water and how much they need for the time being they improvising with plastic bottles which will soon be replaced by war to horses. it looks like technological advances will be key to all future that is all for today's show thank you all for being with us hope to see you again i think we'll be back with more exciting stories about nature and of course of a should i am signed a 3 no bill signing off in the compiler here in uganda.

accuse the organization of falling for a kremlin smear campaign the review comes as a human rights group says one of only said carson ration may be slowly killing him . well earlier i spoke to amnesty international secretary-general agnes and asked what can be done to help the lexan of only. the 1st think that we need to send a clear message that the fact that alex i never really is now the high end. of the war of the prison does not mean that our attention is going to go away on the contrary we know that he is facing prison conditions that amounts to torture including to sleep deprived we know that alex sign of and he survived is one of the few person who survived poisoning by noted shock which he's 'd presenting tremendous challenges to his bloodied and to resolve and it requires specific care that is not receiving we know that he is of the truly detained

because of the position the as espoused and because of the fact that she's a vocal critic of president putin saw all this was reasoned it is incumbent upon all of us to stand up and to ensure that they are sorry teaser pressure understand ok do i tension is not our goal we were going to campaign for him we're going to do everything we can to ensure is freed and certainly immediately that you receive them in the correct harry he deserves i want to ask about amnesties role in that i note that you are new to this role the secretary general regardless back in february amnesty actually stripped election of all the of the title of prisoner of conscious of the status arguably when he needs it the most do you stand by that decision. no there is no standing by or not have been in the job for 6 days amnesty international has initiated as has been made public a process of review of the decisions he twill be made that the the outcome of that

pos really be made public when they're when it's finished which should be anytime soon but the key the key misses here is independently of the e.t.o. sanker says of an organisation such as honesty international the fact is as an organisation we can been equally so an exile of the moment as we we would. 2 months ago in needs to be freed in needs to be freed immediately in needs to be protected against torture and he needs to receive medical care we will not do anything more if if he was still prisoners of conscience that is our campaign it's our campaign for people like him. amnesty international chief i guess last making to us a little bit earlier well the rights group has also released its annual report detailing how the pandemic has worsened inequality and rights abuses in poland

activists are raising the alarm over the erosion of women's rights lawmakers there have approved a draft withdrawal from a european treaty seeking to end the violence against women known as the istanbul convention the measure could open the way to a total ban on abortion. when polish doctors told paulino that her unborn child hit new keep knees and would die upon birth she had few options as of january new legislation has come into effect allowing abortions only in cases of incest rape or a threat to a mother's life. is one of the very few women in poland who has since found a team of doctors willing to attest that giving birth was a threat to her health and her abortion went ahead. but the symbol had better be that. these people are heroes that they aren't afraid of the consequences of

this sick country that they live in. their brave. and they're here to help people and not to serve politicians. and women's rights are under even further threat in poland lawmakers have approved a draft law ordering the country to withdraw from the is turnbull convention on combat in violence against women paving the way for an alternative treaty that would ban abortion and gay marriage critics say the move would legalize domestic violence. that's up to theoretical what you decided just a moment ago is home violence permission this is a green light for torturers so this is a permission to terminate an international agreement which protects the victims of violence you said to the girl yesterday when you see adama your boss be it. one in

3 women has been a victim of physical or sexual violence a recent study finds the istanbul convention's primary task is to prevent violence against women but although the text of the convention has never changed populists in countries like poland turkey and hungry have been politicizing the convention for their own political agenda. in poland last year hundreds of thousands of women took to the streets against the new abortion and the curtailment of their rights those protests have continued despite the threat of covert and a heavy police presence. the scheme. i went to the protest together with all my friends because we knew we had to show we did not agree with what's going on. but none of us ever thought that just a few months later i will be in the situation. yep in the. city. as long as the situation for women in poland continues to deteriorate polina will

not stop fighting which she sees as restrictions on her p.c. rights. let's get around to some other stories making the news naipaul is experiencing its worst wildfires in almost a decade huge places have been raging across for some help himalayas a monitoring side ranked air polity in the capital come on do as the worst in the world international flights were delayed as they smoke blanketed the city. manned mars best known comedian has been arrested as part of a swap against opponents of february's military coup 7 our was taken from his home and young gone by police and soldiers he's been in and out of prison since he took part in an uprising against a previous military dictatorship at least 16 people are dead after 2 buses collided in northern mexico officials say all of the victims were minors aboard a minibus more than a dozen other people on a larger tourist bus were injured in the accident it was not immediately known what

caused the collision. brazil has reported more than 4000 new daily deaths from covered 9000 for the 1st time the nation's endemic death toll is now approaching 340002nd only to the u.s. experts say a local variant of the virus has caused the latest surge which is push the health care system to a breaking point right wing president charbel sonar oh has also opposed lock down measures as damaging to the economy but many of brazil's poorest citizens are crying out for help they say the government's pandemic response has failed them and without more aid many risk going hungry. these protest is a sending a message to their government brazil is hungry. here in sao paulo's largest openness residents say emergency aid doesn't go far enough i mean that is there though my fear is that my daughters will go hungry one of them still under 18.

there's also my granddaughter and i think to myself well they go hungry and that was like most of them up until december the brazilian government provided those in need with around $1000.00 euros per month in 8 community centers like this one of been offering free meals but donations have dropped presidential year both scenarios administration is once again offering help but a more modest amount a community movement known as g. 10 is demanding more. for similar thoughts since in point perhaps the emergency a little of $23.00 euros is enough to buy a domestic gas cylinder 5 kilograms of rice and one kilogram of beans a family can't survive a month on that it's shameful brazil is a rich country and letting its population go hungry and the pandemic is still out of control brazil is a country in crisis and there's not much light on the horizon. let's get some

perspective on this now with simon clarke an associate professor in cellular microbiology at the university of reading in the u.k. welcome to d.w. you've written about the case numbers of the delta mainland brazil being partly attributed to the local variant they're called one can you tell us what makes this new taishan so dangerous. well it seems to spread quite quickly. and it also seems to be have such some sort of resistance to any tricks of state immunity there's also suggestions that some of the back seat on less effective as well so it seems to it really made it so bad a jump. but less sensitive than versions we've had before when it encounters enemy response which of course would sterilize the real me the infection i'm going on so in normal circumstances can you tell us more about the fact you mentioned that it could be partially resistant to the existing vaccines because

needless to say that is very troubling so what is the data actually say on that. well age that suggests that the antibodies that are produced in response to an infection as part of one's immunity normally. less effective the less able to bind on specific it's called. the virus and prevent it from attaching to intercept or on all cells and that made possible also the side that reduction all about one foot in part of the surface may mean that the white blood cells are less able to deal with the virus and destroying it. at the same time we have experts warning that the slower the vaccine roll out the more we can see more dangerous variance why is that. why because if you put of any microbe bit of bacterial virus there are a pressure. to evolve but you don't sort of hit it so that it wipes it

out then it will evolve when you get. a big stations which are resistant or partially resistant to the pressure that are being employed to the cause depression is being applied to them is the immune system is in response to the vaccine so that's why the vaccination these to be done as efficiently as possible we often hear about vaccines talked about as a light at the end of the tunnel perhaps and this goal of reaching herd immunity in the population but can that actually be achieved if the virus keeps evolving. well it makes it much more difficult because you're constantly playing catch up if you've got a vaccine that is only. has going to static you see to a new variant then of course the population is immune to which we're talking about we're going to do is less good it's less effective so it because you're constantly chasing an evolving virus that makes getting that herd immunity well under some

circumstances at least more or less impossible. all right thank you so much for those insights simon clark associate professor in seattle or microbiology at the university of reading though as we hear that appeal to speed up vaccinations the e.u. is medicines regulator is expected to present its findings over a possible link between the astra zeneca covered 1000 vaccine and rare blood clots last week germany suspended routine use of this vaccine and people under the age of 60 after 9 people die from these rare blood clots the a.m.a. has consistently said that benefits outweigh the risks here it is expected to release a new assessment of the drug in one hour's time. and let's go right to brussels our correspondent $1000000.00 is following the latest on this story for us good to see you we will as we said soon get an official update from the european medicines agency is there any indication what we can expect to hear so many what we know so

far is an e-mail fishel told an italian newspaper on tuesday that tea things there is a connection between these rare blood clots and the ester said it could exceed i mean we have to keep in mind that there's something i have to stress here that tens of millions of people have already got their 1st shot of the estrus in the comic scene and only dozens of people get only dozens of cases these rare blood clots occurred so it is rare but this official also said that ema does not yet know how exactly the scene might cause the side effects and 3 expect to confirm what this official told the newspaper yesterday and one possible recommendation could be to only allow this astra zeneca vaccine for older people because looking at the data has so far we know that mostly young people are affected most.
