they expand they eat into rain forests. are there any alternatives? welcome to this week's tomorrow to day d. w signs program. hum oil, no millions and heck, his rain forest subbing wiped out to make way for the oil palms that produce it. it's another assault on the global climate and on rain forest dwellers. 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 1990s. the food industry was in turmoil. as research revealed, the horrors of and fat 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 foods like marine to make these fats more versatile, they can be made more saturated. but this result 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 that it's highly saturated and what that means is that it's very stable, so it doesn't go rancid very easily. palm oil comes from the feet of this tree, which is imagined to be named the oil palm. both the fruit flesh and the kernel can produce oil and palm oil provides a healthy alternative to trans fats. it's relatively thick and solid and so can be

used in a wide range of foods with long shelf lives, without the 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 for biofuel. this possibility has seen demand for palm oil increase almost saturdays sold since 1990 of rich and e 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, our r n 15 has an 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 are growing appetite upon oil has meant deforestation in a single decade. forest totaling size of israel being lost destroying rain, promised to displace indigenous peoples and labor pieces have been documented on palm oil plantation. deforestation destroys habitat tooth, threatening pungent from march and tigers. to the around the town, one of human closest relatives. but the rain forests problems don't end in the rain promised caitlin's economic b, which wetland, 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 since the c o. 2 absorbing powers of trees and

soils are last good amount of the deforestation for palm has it could be called caitlin areas. and pete lens are very a very unique ecosystem and very important. it's a very carbon rich equal system. so given the impact of palm 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 oil palms. productivity is one reason is often the cheapest vegetable oil that money can buy. the truth is oil palm is the most efficient oil crop we have and palm oil demand will potentially double by 2050. 1 way of meeting tomorrow's 1st

palm oil would be to improve productivity research, the jest, but better agricultural practices can boost indonesia as palm oil production by 60 percent on existing land. meaning we could increase production without destroying additional rain promised. yields could be boosted by tools, we already have from mechanization to better fertilizers, as well as know how like lang 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 dwarf 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 what if we can make palm oil without the oil, palm tree, which can make the oil drop 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 the future is still years past 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 that also note about the oil palm tree which

uses so much more oil than other croaks that about how we produce palm oil and there are 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 her 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 factors are gone, the body normally relaxes again. however, when we are constantly being stressed out, we have to look for moments of relaxation. we are 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 said, yeah. hernandez montoya likes to play his drums to the point of exhaustion. he also writes that he then hence will the country side to recuperate. ah, amira skippy own in likes, wellness sessions by she can simply switch off to the world. ah, christina torres tends to prayer and silence to lower her stress levels. mm mm. i'm always to shower and take

a nap. ah, and lucy cannot a likes to go for 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 visa began a study to find out. first men assessed their state of well being from totally

refreshed to supers, stressed to didn't then a snapshot of their faces. afterwards some of the participants went for a walk in the forest and others strolled through 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 some kind of 2nd 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 in 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 it's once a 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. forest and that will end in nature. we experienced positive feelings, positive emotions, and ultimately these positive feelings, according to the theory lead to relaxation and stress reduction. yeah, of course, this only applies to places where you don't work in nature where it's everyday life for you. and as long as the natural surroundings aren't dangerous, the altima light, you know, twenties, but delicious. 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 jahan theresa 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 which ultimately suggest the digital environments can offer stress, reduction and recreation to whom beacon 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 fiscal fuel, hobbin and a twitter safe on. i'm to seen vixens than i mean 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 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, the other 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 a brick wall. 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. mm hm. and this ability of nature is even used therapeutically in the villa, lily therapy, village in the town whose mountains, people with addiction issues, can undergo various kinds of work therapies. one of them horticultural therapy. martin final cook 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 jump and down the unfettered means. i just drank alcohol in the evening, then it'll spiral down with my ticket. christiano oldish also took amphetamines and cannabis as well. has been, we are all my 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 1st, 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 linsmith francis. while i work with plans, it makes me mindful calm and concentrated, and concent hot soon. the healthy guy 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. a sense of anna to defend, the best thing would be if they could apply what they've experienced here in therapy to addiction citations. 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 ms to come to me 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, ah, it seems natural for most living creatures. but what about trees? peters sto essence from the us, sent us the following question. do trees sleep? ah, we all know human beings needs slate. 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 and fro red light. in each case, they found that the whole tree drops at night. ah, the cloud, so 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 i let is read, why and media, if you have a science 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 a thank you. hi, john, this is don. and from move from the world of science, visit our website, or china terms with deering, harvest thrashing, separates the grain from the stalks and leaves of crops. however, what's left of the isn't simply waste. it's a valuable role. material. stole is used as little animal husbandry, or is animal feed. a lot of things the use every day on

later stole. it's more than it appears to be obsessed lines. 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 sport 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 0 anita is it makes a lot of sense to replace fossil fuel products and bio plastic is our one possibility i'd but we will have difficulties in fully implementing this is because we will have to get back to the bio mass to limited cultivation space. you mustn't that on a deep 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 action law worked on the development of his machines for 3 years. the clincher, there are no chemicals used in the production. the strong panels are only steamed and pressed, and even that coating is just made of starch. just as online and for fun from the special thing about the land thought process is that without additives, and he says we confirm straw into stable shapes, be a cheese or other shapes with other methods you typically need to add 30 to 40 percent adhesive. lampart 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, does 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, correct 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 of taker smoothly. it's also technically possible, like however, and small increasing doses omby thing is all in total with all the straw that we have here in germany, i can,

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