the and on that note, that's all for now coming up next on the w. $900.00 special program. i'll be back with more will use at the top of the l. you can also stay up to date on our website . don't forget that to be found a d, w dot com. and you can also follow us on social's twitter word instagram handle is that the w b. 's panell? i'm anthony, how to in berlin? thanks for watching the the fight against the corona virus pandemic. how has the rate of infection in developing? what does the latest research information and contact the corona virus? because the 19th special next on dw, sometimes

a seed is all you need to allow big ideas to grow. we're bringing environmental conservation to life with learning like global ideas. we will show you how climate change and mental conservation is taking shape around the world and how we can all make a difference. knowledge grows through sharing, download it now for me . the notion, 3rd wave is sweeping across africa. more than a dozen nations are reporting the worst levels of infections. there are 25000 new cases a day on average. now, 3 times more than in may in uganda, hospitals are already reaching capacity and oxygen isn't short supply

the, the amount of voltage required at the moment for, for the fish is before you come, we will not be able to make the situation is becoming dire in many regions are we seeing a repeat of the indian tragedy in africa? welcome to our kirby $900.00 special. i'm going to jones ville in this and have you with us. now the world tell us organizations this, across the african continent, the number of cases and death increased by almost 40 percent in the past week. and the 3rd wave hasn't even picked yet. vaccines as we just heard, are in short supply, as is people's patients with the uncomfortable pandemic measures. the message shouldn't be new to anyone, one into half years into adobe pandemic wash your hands maintain social distance

where mosque. but the disaster management officers in cape town, they have observed that more and more people and not sticking to the rules. i pleaded in the really to consider the loved ones, even though they may be resistant to, to comply with people. but they must think of the family members in the loved ones because how they feel like getting dividers. they don't vertical, but they still pick the people i don't and potentially losing love to. i'm not wearing math in public as a criminal offense in south africa. yet many people don't, but mostly versus mosque and everything is for each people, you know what i mean because they have so a lot of money, they don't want to die bullet the eating us is tiring. it is especially for those who goes to school and like kids now they must go 2 days a week. like, it's all it's frustrating man, it's frustrating for a lot of people close to me died because i already joined the 2nd wave.

so i'm, what are you doing this way so far? the province of how ting around south africa? economic have you had this book has been hit particularly hard making up for more than 60 percent of the new infection. scientists expect strict lockdown rule soon, but will the 3rd way fits the entire country harder than the 2nd? no, we don't expect to in the, on the areas at listing the cost of provinces of south africa will be worse than the 2nd wave. why that is because the 2nd wave was very severe in the costco regions of south africa. and we also know from the science that we have done that people that got infected with that the variant had released a very high level antibodies. so we expect to see a kind of population immunity around because of the medical

field. did i get the data management team encouraging the elderly to sign up for what you recall and for more on the situation in africa, we talked to yap boom in cameroon. he's professor of microbiology and the africa representative for doctors without borders specialized in public health. my colleague terry martin had a chance to talk to him. professor bull, the backseat shortage is a problem for the whole african continent. 98 percent of people that remain unvaccinated. the w h o estimates that 225000000 doses are still needed is the continent at risk of being left behind the continent are really being left behind. we are now in 6 months the western country have we seen the vaccine and no, yeah, i totally forgot to ask them for some of the country that are exposed. so it is

true that all the country african don't be the same challenges, but you as soon africa, they are really into challenge. don't have the vaccine. why have you not valuable? globally a yesterday the w h o announced plans for setting up a backseat production hub. in south africa, how significant is this? how fast can i help fight the pandemic on the continent. i think of all it's worth it to have the facts being produced in the country. but for the 3rd wave, for these carrying outbreak going on a bit late, actually what we need is to have those 15 available even for even those who may be late for country life. again, africa was coming, keeping the heard because we've already something good for the upcoming way and also for the other disease. remember that we are going to produce those by not but

my also be important for all the disease for which you 40 by africa. ok. now we've seen the more transmissible delta variant of the corona virus ravaging through india and now rapidly spreading around the world. how worried are you about the impact it will have on the african continent? i think we are quite concerned because you see the country that are no quite the close for the test which is like, you know, bus, uganda. you can, you can see that people, lots of problems coming from which mean that's more exposed of having that's the bargain. when you look at the population, because you like the gun, the way we have actually put our research spent on fund bike because of the increased number of keys. you will have a large part of the population who are hobby or b c. i potential and diabetes. so we have the main concern of the high number of

people who may die already seeing some of the so called morbidity is playing a role there. and you say africa has already been left behind the pandemic of forces, by definition, a global problem. if we fail to tackle the pandemic properly in africa, what implications could that have for the rest of the world? you know, we are all inter if we don't stop there and then we can, africa will be rolling some new value in the entire western population. that's already seen the pfizer, the more then i all of our team, i some point those virus with combat. let me get back thing. so we are all together. maybe we look really relating to the printer and he's africa off of the me. there is no one who will be able to sleep. right. nobody's say, everyone say, professor yup, boom,

africa representative of the research branch of doctors without borders speaking to us from young cameron. thank you so much. again, again, the answer to this pandemic is vaccination. but there are exceptions, perhaps time for your questions. over to derek. call, my government says people who have the disease should get just one. do some faxing because more would be dangerous. is not true. the short answer is no. many, many people who've recovered from covered 19 has since received a double dose of vaccines because the recommendation of most health care authorities in most countries is that 2 doses is still as far as we know, the best way to ensure optimal protection. and all of those people are fine, so we know it isn't dangerous to get the full to dose regimen after recovering from

the disease. but there are a few studies that highlight the question of whether getting that 2nd shot for those people make sense. one in particular, that was published in the journal nature, back in april, it's received a lot of attention. the u. s. researchers involved discovered that antibody response in people who recovered from the disease that it's sword after they've got the 1st shot of a messenger r n. a vaccine tides that only seen after after 2 shots in someone who's never been infected. so although it won't hurt you to get a 2nd dose with vaccine after recovering from cobra. 19 many experts now think that it also won't have really a dramatic impact on how well you're protected. at some point, a kind of law of diminishing returns kicks where we're giving someone who recovered

more vaccine likely won't really improve their immune response much anymore because their body is already locked and loaded to fight off, sorry, covey to. that's prompted. for example, the french authorities to recommend that people who had cobit 19 already only get one shot because that's all the exports there, think is needed for good protection. that advice might change in the future, particularly in countries where vaccines are currently scarce. holding off on the 2nd shot in people who have the disease, could allow authorities to spread the limited vaccines. they have a lot further. me doug williams will be back again next week. no doubt about that. that's all from this covered. $900.00 special thanks for watching the news

. ah cruise

. ah, ah. this he's wanting to understand the world better. we need to take a closer look at the experience knowledge

to the secret to a perfectly fried, to take what give some national dishes, their distinctive character. they all of your favorite dishes with their small and big in our theory secrets 0, dw. oh, it's about billions. it's about power. it's about the foundation order. the new silk road. china wants to

expand its influence with this trade network also in europe. china is promises, it's foreigners, rich profit in europe, and there's a sharp warning you why wherever accepts money from the new super power will become dependent on in china's gateway. year starts july 1st on d, w. the patched forests and dying trees. germany is feeling the heat of climate change. what can be done to help plum trees like samples, the pan african green belt movement has along the way and can medical research be conducted without the oratory? my us and more coming up

the to tomorrow today, your science show on d. w. the mice on by far the most common and oratory animals especially bred for this purpose for around a century. without them many medical breakthroughs wouldn't have been possible. for instance, lab might have been used to study the immune system, as well as in cancer research and drug development. in the russian city of nova appears, a monument has even been erected in their honor. so there are no alternatives lab mice of to indispensable to scientific research does invaluable work at the max planck institute for molecular genetics in berlin.

it helps the scientists here gain insights into congenital malformations. today it's due to be inspected by professor stefan montrose and his team. at 1st glance, it looks just like any other regular mass. but then you notice that 4 of its toes are missing. it was also, we want to find out what causes this kind of developmental defect most. the mouse is a useful object of study because of how closely we can track its development, of course. but ultimately we're investigating a human disease and the human phenotype, as we call it. and it's about patients so exhibit similar developmental defects in leisure. and the researchers use genetic engineering to create the defect altering mass genes, so their offspring are born with abnormalities. the mice now have the same genetic

defect as professors patients at the shower to university hospital and they have, we can see how similar the changes are monday to side, completely different, which is a typical because the physical expression varies widely. you can see several thing is missing here. the other 2 are missing. on the other side, they're only partially developed and they're also partially fused or done by the medicine that under the system contains quite similar to what we see appear in the most amount of genetic comparisons of sick and healthy might help the scientists figure out the exact cause and frequency of the mouth formations. busy the max planck institute lab has its own facility for breathing. the animals. the 1st lubarski mice were breads in the early 20th century. they since been involved in various medical breakthroughs such as the development of insulin, antibiotics and cancer treatments like their counterparts in the wild.

they have a natural curiosity and a rapid reproduction race. what makes them ideal test subjects or their genetic similarities to human? scientists use genetic scissors to alter a message genetic makeup by switching particular genes on or off, or introducing new genetic material. over the decades, the institute standard lab mazda spawn hundreds of new genetic lines, including mice with the predisposition for diabetes, obesity. mm hm. breast cancer, ah, the aim is to decipher the genetic causes of malformations and diseases that might have been key to a host of nobel prize winning research projects. the mice at the institute for molecular genetics are used for basic research, as are almost half of old test animals. the other half are used to develop drug treatments or vaccines. each animal experiment here has to be approved and deemed

essential for resolving scientific questions. but the moral dilemma remains, is it right for us to conduct tests on animals which result in pain distress and even death? currently is often no effective alternative stefan month lows. feeling a couple of weeks for a lot of tests can be done using cell coaches. these days, it's measuring the toxicity of various substances. for instance noir maybe covered when it comes to developing new drugs, you have to see what it does to an entire organism booked. and some of those effects are hard to predict. effect the hard to d, montgomery for years, and that's why there isn't really a viable alternative. you just under the tissues is a spin off developed at the berlin technical university. it's teams develop chips that could take the place of animals and drug trials that contain miniature versions of human organs. this is stamped by this is chip to which currently has

liver and bone marrow cells. we hope it will replace animal experiments in drug development. we also have chip for where we can test all organs and we're currently developing a chip for 10 organ sits in organic. the scientists isolate human cells, for example, from human blood, bone marrow, the intestines are the liver, and use them to make tiny organ emulators for drug testing. researcher louise old myers check into quality of liver cells that have been ordered by a customer for tests. ah, cookie item and labor. and right now i'm using a microscope to examine my liver cells, which i keep in different media. now on day 7, i'm looking at how they're doing and they look quite lively. and so i'm happy of the slide miss. the lab supervisor alexandra lawrence, shows us had the chip works. it has a micro pump that conveys

a blood like nutrient solution from one miniature, oregon to the next. this simulates processes that take place in the human body. ah, maybe it can. we can put some of the junk into chip and because we use human cells, we can gauge the effectiveness far better than an animal experiments better than an animal experiments. yes, this is more effective. the organ ship is placed in an incubator as a temperature of $37.00 degrees celsius. the start of hopes these chips will soon make drug trials and many other animal experiments redundant. but the multi organ ship won't be able to test the impact of genetic mutations. for that there's still no alternative to lab mice. ready ready i will let is read. why do you have a science question? you'd like us to send it in?

if we feature it on the show, you'll get a little surprise from us as a thank you. come on, just this leads to a question comes from veronica in mexico. why is learning to love yourself so important? feel health. take babies. what do they have to do to be loved? nothing with practically hard wired to find them lovable. but soon were expected to be great at school. then learned an amazing job that pays heaps of money. when to turn it off, we supposed to look fabulous to people make demands on us. we make demands on ourselves. we set our expectations, sky high thinking if we liked and admired, we'll feel good about ourselves. put up and that's a house, a cons when it comes to self esteem. a recent study says that young people tend to

be very critical of their appearance because they compare themselves to others, or believes that others find them ugly. ben or x in alcohol abuse, burn out and depression. many people who suffer from mental health issues also find it hard to love themselves. why? because something's missing. and that's a good relationship with ourselves. the relationship in which we're aware of our own needs and treat ourselves with loving care. loving yourself doesn't mean that you worship the ground. you walk on it's about accepting yourself as you are just like we accept the people we love the way they are was turned off. so how can we do that?

step one except how you feel and how you look, be okay with it right now in this very moment. therapists also recommend we reflect on the amazing things our bodies do for us every day. you might end up feeling something like gratitude. and in the moments which is a good step on the path to learning, to love yourself. ah, you can find more fascinating stories from the will to signs on our website and on twitter. the every year, millions of hector's of rain forests are lost in 2020, even more disappeared in the year before. many products contain tropical wood. but where is it from? labels on certified goods are supposed to make their origin more transparent. but does that make them green?

and to me, another tree is being cut down and one of the world's primeval forests, the wood harvested from them qualifies for certification by the forest stewardship council. even though old growth forests are crucial to the health of the planet, the se is an international organization committed to sustainable forest management . them also proclaims far for all forever. there is the man who to the birds, to make sure the forest is helpful. a lot of customers who buy f s c certified products, choose them because they believe it's for a good cause. it is actually true. nature conservation expert p. s. it has carried out a scientific analysis of the f. s fees, certification system, those f a c z goods did fill the f. a c label stands for word that has been

harvested in a variety of ways. it might come from huge, clear cutting in old growth forest. available from eucalyptus plantations in rain forest areas could be in a logical terms. it doesn't necessarily mean responsible forest management for those. so consumers shouldn't be led to expect that get pushed. the, the accuracy is made up of 3 chambers, each with an equal voice, but very different interests. indigenous peoples, environmental organizations, and the tim, the industry. ah, why do you logging companies have a say in the f s fees management criteria? we couldn't get an interview with the f s c global h q, but talk to the head of its german branch. this is kind of to see is not a conservation label. it's

a label that tries to take the realities of our world into account when it comes to generating this valuable resource would as a renewable raw material that entails maintaining ecological standards, while at the same time, respecting social concerns perspective from as far as the f. s. c is concerned that only works the lumber industry also has the same. and that's why even tropical timber from the peruvian rain forest can get the f. s the feel of approval. the stipulations include cutting down no more than one tree on an area. the size of a circle page every 20 years. that conservation group say that even selective logging is harmful. so the delicate rain forest ecosystem on that still is brazil. the wood harvested from these eucalyptus plantations is also f. s. c, certified. in return. the timber companies have to meet the various commitments, including preserving the last remaining old growth forests in the region. the

eucalyptus is native to australia is fast growth makes it popular. but plantations like this are harmful to the ecosystem. they reduce diversity and extract more from the soil than domestic trees. the timber is still f. s the certified because the industry has pledged to mitigate the negative impact me and in the science ecological standards. there are socialist use, such as indigenous land use, right and workplace safety. there are also environmental issues like safeguarding waterways and ground water and reducing pesticide use prostitute middle ends at sweden is also home to over the forests. the trees have mainly harvested by clear cutting between that they supply tends to be foreigners valuable than tropical woods. and that's why the focus here is on quantity, not quality areas that were until recently blanketed entries,

hundreds of years old. a stripped bare, ah, an old green forest clear cut, but even this timber is f s c certified. why? because s s the rules are designed to also take the host countries economic interests into accounts. in return the logon companies must meet ecological requirements that the f s c has deemed reasonable to determine whether the f s system helps protect forests, p s. e bush and his team travel to an old growth forest and russia. and for the certified, clear counting is also permitted in the candle screech and the research has compared areas with and without the fsd level. they found that clear cutting in line with f. s c criteria brings no ecological benefits and it has a serious impact on old growth forests. is in the,

in the region we're studying, we can say with relative certainty that the old growth forest will eventually be depleted the next inflation for leon. as done flayson, the areas left where the forest might be able to grow. again, giving them sides to its value, the land grows hotter and dryer. we may end up seeing less thing. damage to the ecosystem, initiated to go just this was the same. some scientists like p, f, e. bish and many conservation groups are opposed to any logging in old growth forests . they want the priority to be sustainability. the current f s c. rules don't meet that demand. that's why p e bay says that certification labeled onto enough to protect the forests in listen, we had to reduce wood consumption,

companies cutting down primeval forests in russia, paper, tissues, and toilet paper is completely unacceptable. was there so it will vote and sustainable forest management also means asking what the word is used for flushing old growth forest down the toilet is anything but green, even if the wood is certified in many parts of the world, the impact of deforestation can no longer be overlooked, it increases global warming and contributes to soil erosion and desertification. for more than 40 years, the green belt movement has been fighting to preserve forest. it was founded by kenyan scientist, one got him, a tiny w series, african ruth tells his story in a very special way. this is canyon biologist,

one gary my time during a visit to her home village and the 1900 seventy's. and she noticed that local women have very little firewood and water to cook with a situation that how they're thinking back to her own childhood back then, the surrounding hills were covered with forest and the stream slowed with water. the trees were later cut down to make way for a new farmland wreaking havoc on the ecosystem. one gary, my tie decided to take action by planting trees to prevent soil erosion. i keep the areas, water sources from drying up her work held revitalized the mountain region and benefit the entire country. oh my tie was a member of kenya's national council of women, and they also got on board in 1977, she founded the green belt movement tree planting. campaign went on to attract high

profile support in 1998 and a protected urban forest in the heart of nairobi was to be cut down for commercial development on gary, my tie was ag raged. she and other women from the green belt movement took their protests to construction site that side career a forest which had been set up an order to the president. daniel are up more, they spent months, mobilizing public support, other goods joined to protest. president moy refused to budge and sent in right police. the protest turned into violent confrontations. several protesters, including my tie, were injured. eventually, president more relented and ordered construction be stopped. and the activists made plans to restore the foreign lawyer when gary, my tie was convinced the planting trees helped secure people's livelihoods. in 2004,

she was awarded the nobel peace prize when one gary my tie dyed in 2011. she was honored with the state funeral and more and around the world. her legacy is a green belt movement whose message is gone, global. the in honor of one god, my time a tree was also planted in germany after head back then it was purely a symbolic gesture. but now germany too has a problem with drought and erosion in 2020 was classified as being the countries for drought in a row. cut, planting, trees, and farmers fields help save german agriculture. no time at all, it's

a couple 1000 trees, doesn't matter is $25.00 per bundle stick to real human as has big plans. she's hoping to see each of these cuttings grow into a fully grown tree in the middle of her parched fields from me. with the help of agricultural engineer, michel might. she'd already planted some poplar cuttings 2 months ago, but they didn't survive the spring time drought. a frustrating setback. it's unusual, this 50 percent failure rate right now as tough on what other that's happening that we've never seen that before. not even the extremely dry summers of 20182019. then in the spring, at least the ground was moist enough to force the skype that this is you can see me rush way that it's just too dry. it's like a sand bulk. was on the book for let's say it's not going to. so now we'll just

plan some deeper and using shoots that definitely reach down to the lower and moister layers of soil and enforced on boarding systems. and the dried out samplings will be replaced. that concept they're following is acro forestry, incorporating trees into farming systems, to mitigate the effects of drought to this part of ne, germany is among the triumph in the country. maria jimenez wants to be sure she's prepared for the likelihood of even dryer weather to come. then we'll ask you everything turns out as we hope the trees will help us to store water in the fields and flashing a confirmation by employment. work from the trees. sit down very deep roots and extract water from the lower layers of soil and with the evaporation. the entire area is cool down some wash q and that makes it more likely that the crops between them will thrive. the trees will also help create humorous and protect the soil

from erosion which also benefits the crops. agro forestry or a mix of agriculture and forestry is a promising concept in the fight against climate change. experts say that germany, for example, is likely to see not less rain, but 6 percent more. but in the winter, trees can help store that water for the summer when it's really needed. but agro forestry hasn't caught on widely yet, and part because it doesn't receive government funding concepts and when you are applying for assistance, you can get funding to plant trees on farmland. and if you plant too many trees, you'll lose your farm and status. there are all sorts of disincentives that discourage farmers from creating agri, forestry systems. everything we're doing here is possible because we're not farmers where outsiders have been fortunate enough to acquire some land land. because

maria hayman is, is an artist profession, but also manages this farm, just south of berlin, so far without state support in 2007 agro forestry was included in the european union's rural development program. but germany has an implemented it yet. in contrast to france, where the number of trees planted on farmland has increased significantly, studies have shown that 100 heck, tears of agro forestry land produced the same yield is 140 hector's of conventionally farmland. so adding trees does make fields more productive if the saplings take root and about the saplings do get stressed when there's a summer drives that could happen here if we don't get more rain. so we'll do a little poplar trees survive this summer. this time around. it's been 5 weeks since they planted the pump, our cuttings in the sandy soil,

south of berlin. so how are they doing they hadn't met in recent weeks. we've had more rain than in the last 2 years. a lot by our standards . but it's still not enough. the ground is still as dry as in a desert talk, but it was enough for the trees. almost all the new ones we added have growing leagues. they've been growing very nicely. decent allocation of ox. all that stands in the way of the young trees now is couched grass, but they don't use her besides, and instead do the weeding by hand poplars grow quickly, though these still need a few more years. but eventually, maria minnows hopes the poplars will provide her fields with much needed water and shade. even when there is no rain.

ah, that's all for today. he will be back next week with another edition of tomorrow today. until then, by, by the news . the news, the news,
