7 percent the platform with, you know, or this channel, we are not afraid to happen delicate topic because population is growing fast. and young people clearly have the solutions. the future belongs to the 77 percent every weekend on d. w. as we struggle to win the daily rat race, kind of slow walk in the woods, help us relax. what is scientists say straw is just crop plant left of is. but is it really waste? definitely not. it has enormous potential. but we start with pamela plantations. i

say expand they eat into rain forests. are there any alternatives? welcome to this week's tomorrow to day d. w signs program. tom oil. no millions of pictures of rain forests are being wiped out to make way for the oil, palms that produce it. it's another assault on the global climate and on rain forest. well, as the deforested areas are replanted with the trees from which the precious oil is harvested, bad for the climate, but good to meet the ever increasing demand for palm oil is hidden in tens of thousands of consumer products. if you want to know why palm oil is in everything, you have to look back to the 1990 s. the food industry was in turmoil. research

revealed the horrors of trans fats. eating more of these trans fats meant more bad collateral and less goods. which lead to increased risk of heart attack. most vegetable oils are made up of unsaturated fence, but these are relatively unstable and liquid, the making them rubbish. ingredients for food like marjorie. to make these fats more versatile, they can be made more saturated. but this results in those harmful trans fats. talk to your buddy has a tough time of breaking down into the magic fat palm oil. one of the real amongst of pomo is it's highly saturated. what that means is that it's very stable, so it doesn't go runts. it's very easily pump. oil comes from the feet of this tree, which is imagined is to be named be oil palm. both the fruit flesh and the kernel can produce oil and palm oil provides

a healthy alternative to trans fat. it's relatively thick and solid. and so can be used in a wide range of foods with long shelf lives, without homes caused by trans fats. and that can't really be replicated with any ever oil over 68 percent upon oil is used for food. 27 percent is used for cosmetics, detergents, and other industrial products, and 5 percent to biofuel. this possibility has seen demand for palm oil increase almost 7 fold since 990 originate from west africa, 85 percent of the world's palm oil now originates in indonesia and malaysia. and according to the indonesian trade ministry, homo lifted millions from poverty. meanwhile, in malaysia is part of our culture part of identity. you know, our $50.00 note are in 15, has a oil on it. despite the plant incredible properties, there's

a catch. it only grows in the tropics, the location of the world, tropical rain forests. ready ready her growing appetite, the palm oil has meant deforestation in a single decade. forest totaling the size of israel being destroying rain price to displace indigenous peoples and labor abuses have been documented on palm oil plantation. deforestation destroys habitat, tooth threatening fringes from march and tigers, to, to be around the town, one of human closest relatives. but the rain forests problems don't end in the rain, promised patrons ecological, which wetlands, when that dried out to grow oil palm, they can catch by creating evolution and foaming surrounding region. deforestation is also a leading cause of climate change. the c o 2 absorbing powers of trees and soils

are last good amount of the deforestation for palm as it could be called caitlin areas. and pete lens are very a very unique ecosystem and very important. it's a very carbon rich ecosystem. so given the impact upon oil production, it's hardly surprising, but many want to avoid it entirely. but not so fast because the oil palm is an incredible over achiever. every square meter of pomona plantation typically produces this much oil from the same line diarrhea. you'd only get this much rate seed oil, and this much so we've been so replacing palm. oil would mean using more land. we'll palms. productivity is one reason the is often the cheapest vegetable oil that money can buy. the truth is, oil palm is the most efficient oil crop. we have an palm oil demand will

potentially double by 2051 way of meeting tomorrow's 1st for palm. oil would be to improve productivity research, the jasper, but better agriculture practices can boost indonesia as palm oil production by 60 percent on existing land. meaning we could increase production without destroying additional rein promised. yields could be boosted by tools. we already have from mechanization to better fertilizers, as well as know how like laying down palm front to slow apparation and protect soils from heavy rain, new and improved oil. palm trees could also help created to selective breeding or genetic engineering. for example, the wolf palm which stays shorter for longer, making it easier to harvest while more trees can be packed into less land. increased intensification could also have environmental drawbacks, but seems like

a better option than chopping down more vein forest. but even with moves to halt deforestation, and increase productivity, future palm oil demand might increase beyond what today's land can provide. so which if you can make palm oil without the oil, palm tree that the east, which can make little oil dropped inside the cell. now the real advantage of this is that we can replace palmer exactly. we can produce an oil, which is exactly the same. now chris says this oil won't ever compete with palm oil on price, but hopes it could still play a substantial role in the future. even if that future is still use, perhaps decades away, ultimately the problems with palm oil and there are lots of problems with palm oil on about the oil itself, which has amazing physical properties. they're also not about the oil palm tree

which produces so much more oil than other croaks that about how we produce palm oil. and plenty of ways to improve that. whether it's more capital monitoring, producing more oil on the plantations, we already have or producing extra oil using completely new techniques. but all of these approaches could end up increasing how much we pay for our products. given the costs to app and it and people, surely the price would be worth it. normal daily life can often put us under continuous stress, keeping us on edge all the time. fortunately, our body is a well designed to handle stress. fust, the sources of the stress or acknowledged, then it will brains send impulses to the body to produce the pomona which keep us

functioning physically last wonder, a high level of pressure. when the stress, the fact is gone, the body normally relaxes again. however, when we are constantly being stressed out, we have to look for moments of relaxation. we asked on d, w, social media channels, what you do to combat stress. sylvia renita has a passion for 2 kinds of relaxation, yoga and mountaineering. mm hm, said jo hernandez, montoya likes to play his drums to the point of exhaustion. he also writes that he then head for the country side to recuperate. ah, amira skippy own in mike's wellness sessions when she can simply switch off to the world. ah, christina, taurus tends to prayer and silence to lower her stress levels. mm mm. i'm always likes to shower and take

a nap and lucy tomato likes to vessel walks among trees. thanks. arising in, there's a do tend to nature can expect to find genuine peace. something scientists have not confirmed whether in the field or a forest in your garden or in a park. nature gives us the feeling that it's good for us. and studies show that people's moods actually improve, experiencing nature has a positive influence on our heart rate and blood pressure. but not everyone has their own garden or time for long daily trips. can even a short time in nature have a positive effect. a walk, for example, environmental psychologist, god, risa, began to study to find out. first, men assessed their state of well being from totally refreshed to super

stressed didn't then a snapshot of their faces. afterwards some of the participants went for a walk in the forest and others strolled to the city of landau for 20 minutes. after that, another snapshot and an assessment of their stress levels. the next day, the group switched places. the city walkers went through the forest and the forest walkers took to the city. how did the participants feel afterwards? which one of the 2 short walks reduce their stress levels and that kind of like a position would you like a finding of the study was that the men who walked around the city felt a bit more stressed afterwards than those who went for a walk in the forest, what's the end of the study went even further. women looked at the men's photos.

they weren't told about the walks did. they noticed that some of the faces looked more stressed at times and others more rested. the 1st band under stress or relaxed, pretty stressed. and the same man in the next photo, more relaxed, the more relaxed faces belonged to the men who walked through the woods. they came back much more stressed after a walk around the city. the women confirmed with the men experienced excellency community. so a 20 minute walk in the forest or a nature is enough, experiencing nature, even for short periods really helps reduce stress and to foster relaxation. well, hold on to long. how does experiencing nature reduce stress? one explanation is the stress recovery theory. humans have always been part of nature in our evolutionary history, nature has in short, our survival by providing food, water, and shelter. focus is nature has

a positive connotation for us and that will end in nature. we experienced positive feelings, positive emotions, and ultimately these positive feelings, according to the theory laid to relaxation and stress reduction. of course, this only applies to place where you don't work in nature where it's everyday life for you, missile, and as long as the natural surroundings aren't dangerous the are of nozzle, i do not wish but to wallace. but how can you benefit if you just don't have time to walk around the park for 20 minutes or are too sick to even leave the apartment? is it possible to relax in an artificial landscape? jan hunter, he's a research that to some study. participants moved around in a virtual forest. the others walked through a real one. all of them, the virtual and the real forest walkers felt more relaxed, afterwards,

faucets and so which ultimately suggest that digital environments can offers stress reduction and recreation to whom beaten can. one explanation, the theory of attention restoration. in everyday life, we are constantly attentive, always oriented towards a goal. our brain cannot provide this goal oriented attention forever. at some point, we get exhausted in nature. we are attentive in a different way, not goal oriented, more effortless. the brain benefits from that, libya is a fuel hobbin and a 2 different items on the scene. vixen them. when nature makes us feel like we're a little bit away from it all, then we have this underwrite it attention of it. we experienced this fascination a theory, and we can re focus our attention again in the office. and at the end of the day that our research shows that nature does that for us to real nature, as well as virtual nature, neither to an attribute income nature has a positive effect on us. even if we're not out in nature ourselves,

we noticed that in another situation, when a person looks out a window in one hospital study, a group of patients looked at natural surroundings after surgery. the other group looked out at about was oh, the nature watchers needed less pain killers. they were less likely to be disgruntled or distressed. they had a better overall chance of recovery than the brick wall people and were able to go home a day earlier. now does that give us window to let the result means that just looking at nature or images of nature can have a healing effect on us. mm hm. and this ability of nature is even used therapeutically in the villa. lily therapy village in the town is mountains. people with addiction issues can undergo various kinds of work therapies. one of them horticultural therapy. martin found

a cool looks after the patients he wants to stabilize them so that they can manage their lives again independently to patients are participating in horticulture therapy today. 7 years i but has multiple drug addictions. at 1st she resorted to amphetamines. and amanda duncan down the uncertain means. i just drank alcohol in the evening, then it'll spiral down with one second. christiano oldish also took amphetamines and cannabis as well as been. we are all men here to get resources and solve my problems. because before my 1st way to solve problems was by taking drugs. i couldn't get my life together anymore. at least 3 hours a day. they work in and with nature, mostly in the park and in the forest. they also have to find their own project planet and implemented independently

after nearly 6 months of experiencing nature, the to came to a realization lensman francis while i work with plans, it makes me mindful calm and concentrated and constant hot soon. the hopefully in general, 1st of all, to breathe again to relax in nature and to be more mindful of oneself, amazon becoming calmer and more mindful all with nature's help. the brain seems to process natural structures such as trees, branches, and water, particularly easily. that makes people feel positive and reduces stress. mm. it helps both of them are the, shouldn't savannah to do. the best thing would be if they could apply what they've experienced here in therapy to addiction, cetaceans. so they don't turn to drugs. that means they got into nature instead, they go out into the forest and try to simply apply their skills and not take drugs on mr. clinton yet and intact to natural environment is good for our health.

perhaps that will motivate us to protect it. more life begins at night for many wild animals. others seize their activities. when the sun goes down, oh, it seems natural for nice living creatures. but what about trees? peter stone says from the us sent us the following question. do trees sleep ah. 2 we all know human beings needs slain. our inner body clock regulates when we feel tired following the earth's cycle of day and night. animals also have body clocks that set the rhythm for waking and sleeping. many flowers close their petals and hang their

heads at certain times of day. their resting periods also followed the rhythm of day and night. but what about trees? well, it was only a few years ago that scientists were finally able to answer that question with the help of laser scanners, from dusk till dawn, they scan trees with in for red light. in each case, they found that the whole tree drops at night. ah, the cloud millions of laser scanning points revealed that the position of the leaves and branches changed as the night progressed. they moved lower by as much as 10 centimeters in the morning they gradually returned to their original position. ah, but whether the trees like the animals around them are awakened by an inner body

clock is still not clear. but what is clear is that trees do indeed appear to rest at certain times of the day. ah, if our blood is red, why and media? if you have a sized piston, send it to us by a video text oh voice message. if we answer on the show who give you a little surprise as the thank you. hi, john, this is don. and from move from the world of science, visit our website, or china with deering harvest. refreshing separates the grain from the stalks and leaves of crops. however, what's left out there isn't simply waste. it's a valuable role. material. stool is used as little animal husbandry or as

animal feel. a lot of things we use every day on later. still, it's more than it appears to be at 1st glance. strong. basically a waste product. what's left over after the green is harvested and threshed. but around the world, researchers are trying to find ways to turn this raw material into gold. plastic, for example, these products are not made from mineral oil, but from sustainable raw materials, turnips, corn, or wood, and yes straw to the advantage. they're much more climate friendly. this could open up new paths to environmental protection. also with packaging material, because online trading in particular produces vast amounts of waste. styrofoam is

a big problem. it's difficult to recycle and it's not biodegradable. and american company developed an alternative solution with fungal spores mixed with chopped straw there, filled into a mold, and then kept moist and warm for 5 days. the result is a grown packaging element. it's light and completely organic. after use the mushroom straw box simply and says compost in a few weeks, it will completely dissolve in file, it says a anita is it makes a lot of sense to replace fossil fuel products and bio plastic is our one possibility. i but we will have difficulties in fully implementing this is because we will have to get back to the biomass to limited cultivation space. you mustn't on the const inflation ah,

there are limits on how much straw can you sourced the ation. laura cuppa from near munich have developed insulating packaging for shipping food. it protects and insulates just as well as polystyrene, but can simply be disposed of in the garden. engineer, tomas ash and law worked on the development of his machines for 3 years. the clincher, there are no chemicals used in the production. the straw panels are only steamed and pressed, and even lit coating is just made of starch. just as on planning for fun from the special thing about the land tut process is that without additives are tases. we conform straw into stable shapes, be a cheese or other shapes. with other methods you typically need to add 30 to 40 percent adhesive laptop doesn't. with 0 tases pressed into huge bales straw can even be used to build houses. the bales are simply placed on top of

each other like large bricks. this ecological construction method was developed at the end of the 19th century and is be rediscovered today. a wooden construction even allow several floors. the compacted straw bales insulate against noise and heat and create a pleasant indoor climate. and once plastered with clay, thatched houses can even withstand a fire for around 90 minutes. there he collage go. there building material is cheap and free of pollutants. but straw can do much more. our cars may soon fill up with fuel made from straw instead of petroleum. that big advantage in contrast to other natural materials such as rapes eat straw, just not have to be cultivated specifically for fuel production in cause through a germany. a pilot plant is producing biodiesel from straw.

the institute of technology has found a way to make fuel from the cellulose in the straw. they call their fuel bio lake, the straws 1st chopped into small pieces and then heat it for a long time in the absence of air. the result is a bio crude oil that also smells better than its chemical counterpart. this thick mass is the basis for the straw diesel greenhouse gases or reduced by up to 90 percent according to the e. u. in the next 10 years, at least 0.5 percent of all cars should be using synthetic fuels made from residues from fields and forests. that would add up to $2000000.00 tons of fuel with a market volume of $2000000000.00 euros. this is all takers, mcglatian. it's also technically possible, like however, and small increasing doses. somebody is all in total with all the straw that we

have here in germany that we can cover maybe 10 percent of our fuel consumption. although the but at the moment we are below one percent far below one percent saint lou strong. it offers unimagined possibilities. but there is still a long way to go before we could spin gold from straw. that's it for now. he's doing this again for more insights into the world of science in next week's edition of tomorrow to day. until then take care and stay curious, but by ah, ah, with
