climate change event hoffa story. faces wife leslie way for just one week. how much work can really do. we still have time to ask i'm going. to subscribe to use like this. i've spoken truly ungodly about a weave in the time that i've been courting. more than normal yet back to writer seth rogan is not alone celebrity or not pandemic pot smokers are on the rise according to a global survey of 55000 respondents boredom and loneliness of the most frequently cited reasons. 6 the same for consuming more alcohol take

a stranger before the coronavirus arrived 6 percent. to respond and strength alcohol on a daily basis that surged to over 30 percent during a pandemic. your health and well being are at stake plus there is the risk of covered 19 which increases for patients with substance use disorders that's according to analyses from electronic health records in the united states i totally understand though sometimes the pressure is just too much. fun at some point i caved in i couldn't carry on i couldn't stand it so i got something to drag us up thinking award deanna is addicted to alcohol she has done inpatient rehab and psychotherapy she had been off doing for a while when the pandemic hit and she hoped she could stay off it. her dog is a great comfort she also find support and alcoholics anonymous she used to attend

meetings regularly and felt part of a caring community my name had sought to tag a vendetta on katrina i had turned my life around things were good and i felt renewed hope and then came the pandemic and this new world these new contacts were suddenly gone contact with people i was very rough the alarm bells started to ring will it be able to go home i got more and more agitated and the cravings return of the talks on the come up during the 1st lockdown alcohol sales in germany rose sharply in spring 2020 sales of spirits were up 30 percent over the previous year surveys suggest a 3rd of the population has been drinking more during the pandemic. d'anna got through the 1st lockdown without resorting to drink but the isolation started to get to her and in october she had a relapse. and chapman klein a supply didn't just have a little drink and went straight for something stronger the kirk he wanted and i

drank the whole thing of course really fast it was gone in no time and then i woke up right here. a half then i started calling people full of shame admitting that it had happened i know from a self-help group that i can may and even must others and that i shouldn't hide away whole the relapse lasted for weeks and then she stopped drinking again that was quicker than usual she says because she had people to turn to this time several times a week she takes part in an online alcoholics anonymous session that may not be as good as face to face but deanna says virtual meetings really do give her strength and support and help her stay off the drink she also tries to stick to a daily routine to help her through the pandemic creative work helps her pass the time but given her history of dependency there is always a nagging anxiety as an economy and i'm frightened that if the pandemic just goes

on and on and the isolation i will have another relapse and i know that a relapse could kill me but so far so good deanna hasn't had a drink for more than 3 months. deputy of the german center for addiction issues christine joins us in your opinion which addictions are the pandemic exacerbating. you definitely see it shame on him. that this moron thank you my clock is slower in restaurants but reasons to really change people greet at home closer or if the person walking yes solve problems. of our own health of how correlates it's naked then last relationships are there for the next and so we see it cherish more people at home alone

and secure. daytime which wants us yeah very common. so we see here very very problem that can't be too. yeah through awful patterns. you know i was always told never never drink alone but you're telling me to a lot more people are doing this how many more people would you say are actually a risk of addictions during this pandemic. yes and we need what they tell us in the past we have such data for small women and more people. than before our crisis our last name even more slow we have some small others on via situation from 1st life and yes for trying to 20 this

is our our data and one needs while some need for others is there anything in that data that's also new to you or new types of patients who are receiving. there are more. patients and more. brought regulation of clients with the problems. there are a lot more people are barred from our financial issues one month or more later this month or the latest call so slow on. why they are so that shows the market will gain a lot more it's finishing off across the room and many names are. online like any gamblin this is more of brought variation of people who call us and slash us lucky to have one

positive out of this pandemic i guess is the fact that you can get counseling virtually no longer have to actually sit down face to face with someone which may be conducive to some situations or some people but which areas do you see being really tense or difficult to deal with when it comes to the counseling size of side of things. if this becomes more get you to write the work to such a help that small we need face to face contact this is mom uppermost. on how the face to face contact am really see more are very big problems in some other groups the house. yet many people who are sober since years wraps. all have to be very creative to send him home thank you thing with a touch of why why why is that face to face contact so important.

it's a very special problem to keep on earth which you have who you are you have to talk . and face and. it's actually to raise our grants. some people like eggplants this is. how. you can contact with the faith what would you recommend then for people who are struggling right now having a difficult time and who have. turned to be types of solutions or what they think is is a solution but may not be. who who needs help with this market then. you can somehow unprofessional. oh yes father and this is the 1st the most important step to search and to talk.

you can talk to you later if you can talk to a hard one to someone you know to talk. to is this is the most important thing to do to take in stark to talk parking of marketing. what a lot and we are very very mind. you get if. if you it's and. yes this is other it's really the 1st big step thank you very much nice talking to you christine all the deputy head of the german center for addiction issues. and science careers one of derrick williams has been sent an interesting question that's been trending on social media from one of our generic you tube followers. does the vaccine make you infertile. since the start of the pandemic we've seen one corona virus meth after another so it's no wonder that vaccines have

spawned many more this one though that m.r. and a vaccines cause infertility in women is especially worrisome i think because it appears to be having a real impact on vaccine uptake among younger women. like a lot of fake news that gains traction the infertility myth uses science to distort rather than to clarify in this case it twists the scientific fact that m.r. and a vaccine strain the immune system to recognize the structure on the outer surface of the corona virus called the spike protein the disinform ation campaigns build on that with the claim that the spike protein resembles a protein found in the placenta that protects and nurtures a developing fetus that means the claim continues that an immune system primed to

detect spike proteins in order to attack and destroy the corona virus can also mistakenly attack and destroy a placenta causing women to either be infertile or to miscarry this is not true for a couple of fundamental reasons 1st the defense in the immune system react in a highly specific way to the proteins that they've been programmed to detect they have to because proteins are only made up of 20 different molecular building blocks called amino acids but our bodies can produce at least 20000 different proteins from them and possibly a whole lot more so of course there can be structural molecular overlap in many different proteins which is why. immune system has to be so specific and 2nd

is the fact that the placenta protein in question turns out not even to be very similar and molecular charms to the viruses spike protein so short and sweet there is 0 evidence that being vaccinated against coke at 19 affects a woman's fertility and anyway and actually a growing mound of evidence that it doesn't thanks for watching. these plants are true climate heroes. they store huge amounts of c o 25 of their genetically modified leaves. soon they could also enable higher deal which would help in the fight against a food shortage. in the green power in

a small town. come to morrow to do. the next on d w. films that touch our heart made with courage perseverance and talent. by young filmmakers we met years ago at the family on a. what are they doing now. against all odds barely knowledge talents revisited. points to a good. 30 minutes to w. . what is different on the islands of guinea-bissau no you. hear

women are in charge. of the archipelago has it a patriarchal system for centuries and. the rare form of society. women move differently than men. what do they do with their power to move. and how sustainable is this culture. of the good news of the rango starts marching on d w. greenhouse gases trash and heavy metals we humans are really hard on the us. but many industries have been roofing to hell of a drug and science is lending that hand. today we take a look at a few funded projects that are hoping to reduce c o 2 emissions for eliminate them in tiny.

welcome to this edition of tomorrow today the science show on d w. we accompany a telling reset the united arab emirates. the arab country in the arabian gulf was long known for its high energy consumption. but now it's not as attractions and glitzy megaprojects may be a thing of. the countries. and the climate crisis. could come to the rescue. greenhouses near abu dhabi in the united arab emirates the plants here can only survive in this arid environment because they're watered by an expensive irrigation

system and protected from the sun. climate change is already having a major impact here. genetically modified plants that are better adapted to the heat be part of the solution and even help slow down climate change. in his experiments trauma standard car from university has found a way to get tobacco plants to absorb more c o 2 which could help the greenhouse gas out of the atmosphere. he's collaborating with mohamed nasim a biologist who works in and abu dhabi so exciting to meet you. they have weekly meetings from one greenhouse to the next thousands of kilometers apart. they're hoping to modify plants to bind more c

o 2 and boost their yields that would be especially helpful in desert countries like the united. emirates. you've used. the desert is a real threat and just a few kilometers away from the university the government wants all professors to make a contribution to the fight against global warming. and farming lies stood it's abundantly clear that the amount of fertile land is shrinking as a god it is seeing carbon fixation is very important so that we can feed just as many people with less land. the scientists are hoping to supercharge plants to make them better at absorbing c o 2 during photosynthesis leaves consume carbon dioxide and release oxygen using the enzyme rw biscoe but it's not a faster efficient process so up to 50 percent of their conversion efficiency is

lost. to a standard car and just colleague i mean of and sort of are modulating the plant's metabolism to make it easier for their leaves to bind c o 2. they're working with bacteria and synthetic enzymes which are introduced into the plant cells the goal is to slow down foetal risk ration process and much c o 2 is released instead of stored a synthetic metabolic cycle will also give the process a boost. in. building 2 things into the plants this synthetic cycle enables them to fix e.o. to much better and it's quicker and a larger quantity is stored. the other has to do with photo respiration c o 2 is lost in this process and i can block this undesirable cycle by changing the

mix of enzymes so that c o 2 is either not released or is immediately recycled. so far these climate friendly plants only exist in the laboratory but carr and his doctoral student. have developed a computer model that shows what their super charged plants might one day be able to do. by passing photo respiration and modulating the metabolic network will keep carbon dioxide inside the plants instead of releasing it into the atmosphere plant's modified this way could bind 5 times as much c o 2. as a. in mathematical terms the model works that's a really important result that has come up with in her calculations. and that means that i can perfectly augment the blocking of c o 2 transporter with the synthetic cycles. and.

these computer simulations are being put to the test in abu dhabi the university greenhouses growing tomatoes and. will their supercharged plants have a higher yield and by more c o 2. genetically modified plants are permitted in the united arab emirates under highly controlled conditions one day supercharged plants might be grown in secure greenhouses and the technology might also be used in other applications. trees for example could be enhanced to store more c o 2. algae that grows in flooded sand pits near cement factories could be modified to bind more smokestack emissions. and golden rice which already boosts vitamin e.

might also become more climate friendly. this is an important moment in time where the c o 2 into. it's a still unstable year where new conditions have not yet been established as the ice free polar caps like the thawing of permafrost is that is why we need to research fully reversible and mild climate mitigation strategies so that we know which way to go when things get critical and say 10 years' times what. the scientists hope that green genetic engineering could help boost tromp yields and at the same time we do c o 2 emissions. if their research pays off supercharged crops to help solve 2 of our biggest problems. global hunger and global warming.

pulling greenhouse gases out of the atmosphere is one solution. but eliminating emissions would be even better. the steel industry is one of the dirtiest industries in the world the blast furnace is that he said with coal are a big part of the problem. might hydrogen be a green a solution a german still produce it is betting that it could. corpus germany's biggest steel producer and also its biggest c.e.o. to produce its factories pump out around $20000000.00 tons of carbon dioxide a year amounting to almost 3 percent of total c o 2 emissions in germany and the furnace is they used to play a big role in that. the theory is this is a blast furnace one with a conventional design that normally uses iron ore and coke as

a matter that will be. the 100 meter tall furnace is filled much like a pepper grinder a for. hand blows in hot air and coal dust at the bottom ion occurs naturally in oxidized form so the oxygen has to be extracted to obtain the pure metal that's where the coke or carbon comes in. the byproduct is carbon dioxide. as the gas rises the crude pig iron melts and flows to the bottom. to do sport based company wants to reduce those c o 2 emissions and eventually eliminate them. they're carrying out tests to see hydrogen could be used in the furnace instead of carbon. you have. currently completing the initial phase 1st you have to figure out a good way to get the hydrogen deep into the furnace office. but.

it's a tricky process because hydrogen is a highly reactive element when it's combined with oxygen it forms a highly combustible gas oxy hydrogen. every 2 hours the steel workers tap off the fresh. samples are sent to the laboratory on site where the quality of the iron and other raw materials is checked. the hydrogen technique is also a new territory for the engineers here. and of course they have also being part of this transformation is a huge challenge it's not as easy as people might think that if we know injecting hydrogen into the furnace that means our tests also have to be changed to dust off the composition of the gases difference and we might have to change other parameters take. in the labs trial fantasies the engineers carry out test runs with

a variety of additives and gases. they need a huge amount of hydrogen which is also a major challenge. these blue cylinders supply just one of the furnace is 28 injection also lives are. at the moment we have 2 trucks delivering the hydrogen to us in rotation multiply that by 28 and you can see we have a crazy number of deliveries here it's not feasible over the long term which is why we're laying a pipeline. 130 kilometers south of this book is a company that knows all about pipelines and that's also investing in hydrogen production the shell rhineland refinery is the largest refinery in germany. shell is now building the world's largest electrolysis plant here on site the facility will use electricity from renewable sources to produce green hydrogen.

the coronavirus pandemic has slowed down construction work somewhat. but the water pipes are already in place. see if. it might just be water but it has to travel 700 meters we had to use some pipe rack with stainless steel it has to be heated to prevent freezing it's not just an ordinary part. of our national life. now it's on to the next stage the refinery direct is coming to the site to see how things are going. he's already making plans for the future. he just wakes up with a tape on fame mayor of what it is project has a capacity of 10 mega watch it's a start and we can learn from it we want to get the technology up and running to see if it scalable to 100 megawatts or more what we learn will help us move the

technology forward and that's what makes it so fascinating because fossils of all the spotlights article for city. hopes that one day it might be able to export its green hydrogen. the steelworks into sport also a promising customer they also have big plans in store. by 2050 at the latest to suncorp wants to use no coke at all in its furnace is. for that they'll need an all new blast furnace one that will be fed with iron ore pellets and hot hydrogen. instead of dirty c o 2 the byproduct would be h 2 o. water in the form of steam. and they want the furnace to be powered with thermal energy sourced from green electricity. they've already seen some promising results. possible through here but this is

what you've already managed is to shift the conversion of the hydrogen deep inside the furnace interior then the hydrogen doesn't just combust but extracts the oxygen from the iron ore leaving us with workable pig iron in the end. wasn't. pig iron produced with this method is higher in quality too when coke is used the pig iron contains unwanted by products like sulfur and phosphorus which have to be removed but that's not the case with hydrogen it's a truly clean fuel. germany did it in 2020. bangladesh did it almost 20 years ago. but the ban on plastic bags hasn't made much of a difference that get. out tentative slate from natural jute haven't caught on. now a scientist in baghdad may have found

a solution for that. this is a market at the edge of the bangladeshi capital dhaka. the fish section is very busy as all these. many species are on sale at the stalls. and everywhere single use plastic bags everybody uses the. u.s. genger has been selling fish here for 10 years. he knows that plastic bags are bad for the environment but he says his customers should take responsibility.

on the back and not bite us. these bags are everywhere and that's why we use them if we could get different ones we would use them people who shop at the market should bring their own bags or baskets but nobody does well of them myself. right beside the market is a lake it's very polluted and plastic trash is everywhere. disposable plastic bags have been banned in bangladesh since 2002 but the authorities don't enforce the ban. one reason is the lack of alternatives there are slight and cheap and easy to use as regular bags made of polyethylene. eco friendly jute bags are available for sale but they are rarely used bangladesh

is the 3rd biggest producer of jute in the world. the abundance of this resource inspired scientists mubarak ahmed khan to develop a biodegradable polymer derived from jud fibers and then bags made out of it. when i lived. in bangladesh called the golden 5 because that's why the prime minister gave up a product the name calling bag or sonali bag it's recyclable if you dissolve in water you can dry it and make something new with it but. the tsunami back went through a long period of development and testing before to change its present form ringback . if

a bag is burnt it doesn't release dangerous chemicals the way polyethylene does. raji waste you are the source materials for the batch they look as if they're made of regular plastic but they're not. like that i'm not the least put it 1st if we preach fraud to you to tell it's white you know should i pick on that cinemas if to put it then we extract cellulose from it but it may soon. be processed the cellulose to make it will to soluble approach him a bit again rather than he will but i don't normally do that i mean for me then we add a binding agent it's at them like that bind them out of them that yields the solution if they don't mr good at the solution to. a solution then it's from that solution we produce the box when you say there is methods to make them.

concepts the manufacturing process is entirely natural unlike that for bags made from other plants. such as manual for the people of sugarcane. our bags are completely biodegradable compostable and water soluble water but they're also dependable and we can produce bags that last as long as customers need them to. protect. the pollution of the sea the land and the air is a big topic right now. to learn from our bags are a good environmentally friendly alternative. when i leave. the government backed pilot project to manufacture them proved a success. the challenge now is to develop large capacity machines and scale up production so that so nobly bags can be made available across the country.

and now it's time for your questions this time we've got one from south america. thank you hello my name is. and i'm from colombia and i have a question for tomorrow today why is plankton imposing for a. town. deal good question let's take a look at sea water one teaspoonful contains up to a 1000000 organisms viruses funky bacteria tiny algae and other creatures. all organisms carried along by the current accounts to this point even large ones like jellyfish but most are so small you need a microscope to see them. it's quite beautiful and when they multiply a lot you can even see that from space. plankton are extremely important for the

global ecosystem here it's 3 reasons why number one breathing without plankton we couldn't breathe. phytoplankton that is plant like plankton a photosynthetic their fuel by light energy from the sun and give off oxygen in the process the way trees do too but all in a fight a plankton release a lot more oxygen than trees do photosynthesis also involves the consumption of carbon dioxide so phytoplankton help combat climate change by pulling c o 2 from the environment number 2 eating plankton a key to the global food chain phytoplankton a region by 0 plankton that is tiny animals eat tiny plants fish and other larger aquatic creatures eat plankton even some of the biggest animals eat it like some species of whale. and a lot of what we eat was reared on plankton without them the entire food chain

would collapse. which brings us to number 3 building plankton are also the source of raw material what are these buildings have in common like instead. it's formed from the shells of dead microorganisms that gather on the sea floor. over a 1000000 years also deborah has cemented together into rock one cubic centimeter of chalk a kind of limestone is made up of hundreds of millions of tiny shells. just think how many there must be here. plankton may be very small but sometimes it's the little things that play a very big role. by the way the amount of plankton changes seasonally and in response to other factors

. but in some regions there's been a massive decline in the us and experts what can we do to brits. ect plant. one of. the biggest basher is reducing atmospheric carbon emissions. the 2nd is related to fish or ice the larger creatures plankton and fish are important for the mineral nutrient cycle. or for. if you take those creatures out of the system by overfishing for example then you also change the mineral nutrient cycles. then and. that also has a direct impact on phytoplankton because they need mineral nutrients to grow. in town as plankton greece and changed over time.

form land we used to base our approach to the oceans and what we knew about land ecosystems. not at 1st scientists focus primarily on how mineral nutrients are distributed in the ocean and how phytoplankton respond to these nutrients. but as you. but we are now discovering that the many interactions among the plankton might be more important. then that's the direction research is now going in. looking at the interactions which species are her together how they are distributed and that kind of thing. can best use interacts well the data shows that these interactions are very important one of the most important involves predation.

grazing pressure from playing tennis. if we look at these types of interactions in detail then of course rediscover coming. you know facets of trying to ecology. get done and there come on the traditional i have to settle for planting a quarter of a typical example diatonic. and there's mother with the fifty's car surges have examined the robustness of their salissa fied cell walls and which animals eat such creatures and how the structure of these shells offers protection from various predators and. the shoots given season for should know put up or down beat. it out what is right why are great but i'm a few. do you have a science question you'd like us to answer. send a date as a video text over oyster man if we featured on the show you'll get
