always does everywhere in the industrialized world it's a part of our everyday life like this plastic bottle in my hand for example hundreds of billions of them are produced from crude oil every year many of them and more to recycle and end up in landfills it's all in our oceans it takes 400 years for each one to decompose into micro particles and even these micro particles remain on the planet for ever how do you change these what have you or 200 tips and solutions to this problem that's what we talk about to be alone welcome to equal india and some of that. despite increased environmental awareness a lot of the east still ends up in nature many a time in places where people go for the jewel of a relaxing story this is where blogging comes in

a trend that combines collecting the garbage and jockey or digitally from sweden blogging is a new form of equal freak this and india is not far behind in exploring it for the . dominant bevies on a mission he wants to get india as the streets of it is a monumental dos people throw away 25000 pounds of plastic waste of it but he has been gathering help for some time now. found thousands of allies across the country for 5 years they have been practicing trash them. but. it is a new word combining the swedish word lucky. lucky with jogging outdoor running it is catching on across the world in india it is the still early days for the blog movement. when you look at people like akbar sanitation.

coming to your pieces and cleaning up your street. what do we call them we call them got to. we have got to do well because of that but how do you message so i do mission statement we wanted to make cleaning up and the people. are winning . but. he seems to be on the right path is now well known as a success when you go from this person has organized 400 blog drones and 75 cities since 2019 at the end of the crash stricken to a city collection point. this is not a wonder. whenever we do some good thing so there is one particular. i think. would not be in my body and i am feeling very much in order to get this point of fame so i'm feeling really good and i definitely. do know is

one of the city in the state of maharashtra and quite a property of the birthplace of india's plug moved. river gone and funded the movement here has been with the group ever since support has gone. to towns and 400 members. a lot of people that don't really think a lot of. their job and you. have to take the bus the challenge and reach people there. so why do. basically. the notion of combining environmental activism with fitness to help people when vivek fired up their army of followers. but the bloggers are ambitious to don't just want to collect crush they want to do something with. a lot of cash

which we collect. so for the next week. we'll have you know. i didn't find a lot of last words. so we'd like to we're going we're going to get out of the great anger there is a company government. you don't really mean it would have been you well. selling the bottles opens up a source of income for these women. however blogging is only one way of getting close to nature. said he's researching the healing effect of foodland on the stressed out city dweller ecologist organizers full moon the strongest to the goods. no want to speaks out in the area of south dead there is nothing to be heard of the nearby megacity. airplanes.

not that will make it romanticized which i mean often people who are sort of associated the walk to be my attempt was use the silence and the sounds and just the feeling of being in a forest. that excitement that it gave people the sort of cats that attention and then talk of activism and again the naacp and about the fought us and the authorities and to make it fun and they just about. me to. rustling leaves. rushing brooks chirping birds don't know later high as mental equals spot the plague city slickers. my biggest takeaway has been the silence especially.

you know physical activity learning something new about the understanding issue and you know that this. is just. you know. indians are increasingly enthusiastic about environment and they mostly live in cities and graphs long ago that something has to be done the plastic all over the streets become. life which will take at least 450 years to break down the bloggers have no intention of reading that not. be clear. and just collecting garbage is of course not the only way to solve the waste

problem especially plastic waste instead a feasible alternative to plastic bottle plastics seem to be promising for now they're more by would be credible than any conventional plastics available to be a reporter look at some of these alternatives to find out if they could help one of the biggest problems facing. this is supposed to be the current state of the future . obviously not specifically in this because it looks like crap. what this this this. this is supposed to be the plastic the future looks like no more plastic feels like more plastic. acts like almost nothing but is made from slots it pollutes less than conventional petrol based plastics and in some cases is even biodegradable perfect right plastic pollution problems so well it's

a bit more complicated than that. so bioplastics you may have seen them in form of biodegradable plastic like this coffee cup so or cutlery and but not all bio plastics a biodegradable. bioplastics are called that because they're bio based meaning they derive from biomass like sugar cane potatoes. instead of petroleum big companies like coca-cola and done on have already started using bio bottles they're functionally identical and indistinguishable from petroleum based bt one of these bottles is bio based one is petroleum based and there's no way i can tell that i'm currently bioplastics only make up about one percent of all plastics but the market is growing the demand far exceeds the entire industries ability to supply right now this is really a forward she works for one of the world's biggest bioplastics manufacturers nature

works. like nature works are growing in large part thanks to consumers like us wanting more eco friendly products and compared to petrochemical based plastics it can be 2 thirds to 3 quarters less carbon per pound at the factory again this can vary depending on how where and what they're made but in general bioplastics production the myth less greenhouse gases. making them feel retic lee a more eco friendly alternative for making plastic out of biomass isn't a new idea one of the earliest manmade plastics was a bio plastic called poxon known today as celluloid which derives from solos found in plants 40 even produced a saudi being part. made out of you guessed it soybean derived bioplastics but eventually petrol based plastics took over they were easier to produce and more versatile and that demand only kept on growing however bioplastics are experiencing

a comeback and production is projected to grow significantly in the next years. but let's get into the tricky bit about bioplastics just because a plastic is bio based doesn't necessarily mean it turns back into soil. comes from the chemistry of if you can produce meat t.d.'s from sources they can. use this as. a chemist who has studied the biodegrade ability of plastics so let's talk about non-biodegradable plastics quick and easy chemistry explanation this is ethically derived from petrol which is formed into a long chain to become polyethylene or peat this carbon chain makes table and durable but also really hard to break up making it known biodegradable. this is

a bio based material in this case ethanol and alcohol you can make the exact same structure the exact same polyethylene out of it the leftover molecules become simple h 2 o. water there are many different processes but this is how a bio based plastic can be known biodegradable. remember the video from the beginning that was by you also a non biodegradable plastic it acts just like petrol based plastics and just like them can clog up and accumulate in marine animals actually about 45 percent of bioplastics produced today are not biodegradable ok so let's talk about the by the grain. of all plastic. for example this plastic which is poly lactic acid and it's designed so that it can almost entirely degrade into c o 2 and water similar to other biodegradable plastic.

like this this is made out of pollen lactic acid and it says compost of all calm possible means that it biodegrades in a specific amount of time in a specific condition this it's 3 months in an industrial composting facility you need to collect them when you need to send it to composting then only. ok if you don't collect and you just sink and then run and. you can create this same problem a few of. these in the converse in facilities depending on where you live are few and far between and many don't even take on possible plastics because they are so hard to distinguish from conventional ones on top of all of this the plant for the growing for bioplastics can have a big land water and carbon footprint diverting crops away from food sources and harming the environment with pesticides. some bioplastics companies are working

towards growing and using local sustainable crops or producing plastic from buy a waste instead. it's the consumer doesn't necessarily 'd know. what where the inputs are from bio plastic so it's really hard to. the consumer this is close who coauthored a study that looked at the land water and carbon footprint of bioplastics. and we felt you couldn't easily replace. 'd the plastic even just for a way where you want to use plastic because your requirements are so plain juice and water comes through so a lot of those they calculated that to. replace all plastic packaging with bioplastics we need more than half of the world's corn production. it's a. sad but it's true that doesn't mean that using bio classics never make sense

there are a few applications where would be better to switch from petrol based plastics number one being food related plastics for example this teabag back can contain plastic things coffee cups saws all food packaging in general because packaging that yeah has inside of it or as touch does not get recycled so the only in the best way to handle that type of product is through composting so replacing all of these conventional plastics with easily biodegradable for example or home compostable bioplastics could be a good idea. other examples are 4 wheels for agricultural use that can be plowed under the ground or fishing equipment which reportedly makes up 10 percent of all marine little replacing all petro based plastics with bio plastics is just not realistic and to be honest downright unnecessary one study estimates 40 percent of plastic produced is packaging

a lot of which is avoidable if you kill those no civil court order to really 'd 'd . look all of that right i know it's hard sometimes i know it's less convenient sometimes i mess up all the time bioplastics can be better than conventional plastics but it has its costs it is not the perfect solution the only way to plastic pollution is to use less of it with a bio based on not. even if we try to reduce the amount of garbage we generate every day we are far away from a 0 waste planet some amount of waste is in ever to good especially in large cities waste management is a complex issue and if not done correctly it can have some grave and far reaching consequences our next report from russia will help us understand better. the fumes from the landfill start just being a horrendous lee. your eyes burn your throat hurts and you feel sick lyrics

it's as if someone's pouring water down my throat it makes me cough i can hardly breathe they say everything's alright but to emergency services have to talk to $25.00 times over the limit. up with them it's all because of the dumped here. by here julia feticide means about 500 meters from the house she was born in. the alice escape plan a field near the village a shop you know is one of the dozens all around the mega city of moscow is $32.00 hectares in the area for about $45.00 soccer pitches. only a few years ago the pit was some 30 metres deep say local residents now it's a hill rising about 20 metres high and it keeps getting bigger as to the populations health problems. if it is a haven us is that some days it's think so unbearably she couldn't open her apartment windows her children 8 year old delia and 7 year old cover slava started

feeling ill more often i think the point came when you here couldn't take it any more she moved away from her home village shop over 7 kilometers to the town of clinical one. that would the little ones always had something wrong with them one day the pediatrician told me their lungs were making rattling noise there i didn't have to think about it i started looking for an apartment hearing clean for us later after the movie went back to the same doctor an oh what i thought what a miracle the noises in their lungs were gone how come very simple we've moved away from the landfill. effect so he gave us case was no isolated one waste disposal is one of russia's most pressing issues greenpeace figures show less than 4 percent of waste being processed and only 2 percent going to incineration plants the rest goes straight into dumps ironically the country with the largest

land on earth can't find a space for the estimated 70000000 tonnes of waste its population produces annually moscow's landfills in particular are ticking time bombs many of them fail to meet. the official safety standards contaminated soil water and air over and over local residents opposed test it as here to congress but rarely have they seen in the results. julia fetzer either has joined the effort for clean air in her home region she and her fellow activists pooled their funds and bought a gas analyzer that measures radioactivity chlorine hydrogen sulfide ammonia and other politicians. who would have it up with them but will use this data to compile what we call him up of the stands for the whole area and then decide if you can go outside with the kids who are not meeting. their results are alarming the activists report them to the environmental agency regularly in 2017 the state

emergency services finally had to react and measure 25 times the maximum allowed for hydrogen sulfide activists took the matter to court but with no success our reporter contacted the landfill managers and the city of clinton but received no response. and so the offense really has to consult her detector before she takes all children outside to see what is the way analyze the air today would you know right now it's looking good so we can go visit grandma and shop over . julian fellowes so he is 67 year old mother tina. still lives in their home village. can you come and have some tea and sausage with. her grandchildren maija coming to visit even if only briefly her house to his perilously close to the landfill but she's not going to move away do you where

would i go who could i sell my house to with all that stench out there they're not exactly lining up and how could i live in the city i only get a pension of about $190.00 euros and i'd have to pay $130.00 euros to rent a one room apartment. they visit with grandma for a couple of hours you know if that is how he shows her kids her old pretty quickly before the win turns and the smell is unbearable again all her efforts to have something done about it have been for nothing but that's the one so i don't know how long we can keep on fighting this is we're too few and we're starting to feel helpless and desperate for more things to mcchord it's. a mountain of garbage keeps on growing and there are even plans to expand the landfill. when garbage ends up in landfills and is no longer to recycle it leads to wasted

role materials these raw materials have the potential to slow a new pope was what every fall may be a quiet some students in the netherlands proved to be true they demonstrated that you can make an electric car from gaap which. this car is literally rubbish complete trash. but we use a whole different kind of waste and also recycled waste but mostly on sort of waste as well luko is the brainchild of students from the i'm told in university of technology. fund and is the dutch teens project manager. so our system is built out of this material which is flex and the recycled beauty bottles and we have some other cool materials so that's what this actually and that's what we use in our interior as well and this is normally what you throw away in your home on sort of household waste is very often. their message is a simple 11 call it when it's recyclable material.

we're only with $22.00 students and not all full time and we start from scratch so it's just from nothing till this and we have to think of all of ourselves and we don't nobody's ever build a car before. starting from scratch can sometimes be an advantage and help to focus inventive moments on the essentials. in just 18 months the students created a minor miracle a car fashioned from recycled waste. championing the cause of sustainability while at the same time for the ring their own potential. so that's very difficult of course but very awesome to do because you learn a lot about it so that's the upside of it so i opened up that was for you maybe i should look at 6 better is there there are more 6 smaller bags and can easily be

swapped for 4. if they're better resume c. so shocking to see it so clearly sitting in their system a sort of. versions are actually made out of coconut cyber or share recycle the. people's 1st formal business this way to game serial this is the core seat 2nd so they are very old school. that is cowered by 2 electric motors and the rear wheels. it's a dream come true to drive. it's a sporty looking little move with the top speed of around 90 kilometers and. fully charged it has a maximum range of 220 kilometers. we really hope that all the car companies a lot of companies start using race materials because you have you really want to

show that it's possible in many of the occasions and i think it will take some time but we are seeing you know it's more and more companies are starting to use it or bio based or race. in the interior and we want to show it's also possible to build a shetty out of it and hopefully in the coming here we also see that happening. behind tobin university of technology has a reputation for innovation and creative young minds to keep on plugging away instead of resting on their laurels in a previous project students looked at another future mobility option and entered the ultimate competition the world solar challenge in australia the state team went on to ski for top prize in the cruiser class for years in a row. the problem of producing too much we used is one of the biggest challenges of fossil

side to now and in the future so next time you reach for a plastic bottle be a very of the consequences of your choices we've shown you many solutions to be on equal. useful takeaways from each one of them i'll see you again next week with more such solutions as always until then from out and out of to even india and germany are good but. with a. little

. bit of. thanks but. it's a constant companion it. makes us feel. headaches dizziness and tonight is just some misses it can be caused by not the. line is that. and what can we do about it. in good shape. next.

month so for optimizing city that minimizes emissions separates waste and in the best case recycle sage. can these visions become reality they are urgently needed. in the city the living space of the future with room for everyone. 3. 160 minutes. formal or. sleep. cheerfully. it will suit me. to take you.

to discover how many. subscribe to. documentary to. lead. the following months ago from his new francisco flame sled stop. ok wouldn't it be great if you could silence noise just like that we all know this only works on t.v. let's face it if i would sit here every single day i would presumably be deathly.

sick in any case especially road traffic noise is a risk to your health and well being headaches dizziness and just some illnesses that can be caused by noise. a moment of quiet nothing but. blissful. unfortunately. our everyday lives are usually different when confronted with all sorts of noise 24 hours a day closing out isn't an option sounds become noise when they disturb us often when they're very loud but it's not just a question of volume psychologist daniel crystal says noise can't be described in purely physical terms. noise isn't an acoustic property it's a sensation but it is related to the acoustic properties of the sound. the louder the sound the more likely it is to bother me so it also depends on the situation.

it's my favorite bands playing a concert i won't mind it being really loud but if i want to sleep my favorite band hopefully won't be playing in my living room and an important factor is whether or not you have control. a sound that i can turn on and off is less likely to disturb me than something like street noise or aircraft noise because i can't control those . noises in our environment can especially become a problem when we're completely at sea it's no wonder that lots of people are affected by traffic noise and noise can cause illness even if we've become so used to a soundscape that we no longer consciously perceive it noises can still affect our health. for example scientists are studying the connections between noise pollution and mental illnesses such as anxiety and depression. and immense as to noise pollution is

a huge factor in stress especially if it persists for years off a gate we just completed a new study where we were able to show that noise pollution come predict the onset of anxiety and depression even 5 years later as well as insomnia for. but not everyone can choose where they live and work for many the only option is to cope with noise as best they can put it in fear. and i would advise people not to limit themselves because of concerns about noise but to continue with their activities and do the things they enjoy stress up to pawn that's an important way of reducing stress and then you can avoid the vicious circle of noise pollution and possible anxiety or depression it often. these days away seas of quiet are rare and therefore precious. the important thing is to seek them out. as the philosopher friedrich nietzsche remarked the greatest events are not all

noisiest but our stillest hours. and next spring at the technical university of berlin since january 2019 he works at the institute of fluid mechanics and technical accusatives researches noise information and how assessment among other things. hi hello was a theory of how i thought i see through as if you do what you doing here i measure that the level also your traffic noise at this very busy street yeah so it's quite noisy isn't it yeah as expected it's. much lower than 70 to be an average so it's very loud so it would be very appropriate to live here yes i would like to read through ok so what about if you go to something more quiet great ok. it's a very very busy street it's very noisy is there

a difference between noise and just sound yes there's a difference and. it's noise unwanted if you think it's inappropriate it details it's a noise and therefore it is a psychological phenomenon it is not the physical event it's in the printed auditory event this makes sound to unwanted noise sorry depends on my perception of what i do about this. yes yes and therefore it is difficult to measure if such a device unwanted noise because it is is your perception. a lot of engineers tried to reduce noise from cars but it's still noisy so so why is this there's a simple reason because we have so many cars on all of our roads so i think of it as a single car is quite then enough parsed but we have much more cars on the roads

a day out for the road traffic noise is quite high in our cities so but when you take a look at all the capitals in this well to me the cities are getting bigger and bigger and more mobility more mobility so can we do anything involved in noise there are some approaches to promote develop being in cities to reduce noise on the technical side but also to offer torque to places like parks green areas because we can observe that it is quite quite beneficial for the for the health and life satisfaction for people living in cities but be divided say well i love this noise here it's great it's a booming city and i like to watch all the cars and i like it here and there's still some made negative effects on me. i would say it helps if you have a positive thinking it and a positive attitude towards the noise over city then it might decrease to

a certain extent potential health effects but we can't close our all ears. we are always listening and therefore we cannot really adapt to noise it always stressed therefore you can't avoid any health related risk. even if you think that the the so nice all and even if i like the noise even feel like a lot but it's quite simple if you listen to loud music over a long time then of course you will. have hearing impairment often soldiers at its most exposure so let's 1st have a look at how our ears work and how they do this 24 seventh's. this is how dangerous prehistoric times when you shut your eyes for some while and rest i'm not even having it you're on the dinner menu from competing species. bums . that's all it takes despite sleep mode the ia is wide awake

it's registered the telltale sound and in a flash it transmits the signal to the controls and has a moment later the adrenal gland releases the stress hormones adrenalin and noradrenalin they activate the unarmed systems in all the important organ. the heart immediately steps on the gas to increase the body's oxygen supply. blood vessels constrict blood pressure braces digestion is now of minor importance it gets decathletes from the bloodstream maximum blood supply has to go to calls the body needed for survival right now the muscles a crucial. a rude awakening that at least the internal systems are already running at full speed so fight or flight in this case best to make a speech except. if you have this close but now it's time to replenish the lost

energy. after a short delay the stress hormone cortisol is also taking effect fat from the body's deposits is being made been iced. in the liver should a is manufactured and released into the blood. coaches allman shows that we don't run out of fuel when fleeing from danger it's an ingenious survival strategy for emergencies. but ever since we traded life in the wilderness for roads houses and traffic there's been a problem the alarm system that protected us by peds from saber tooth tigers for thousands of years now seems to have run its course. even though modern sources of noise can be annoying they rarely signal life threatening danger. but our gnome systems still react in the same way beware of saber tooth tigers to prepare for a fight or flight. a certain stress hormones are released unnoticed during sleep and

particular cortisol levels a permanently elevated when this continuous noise we get into a fight or flight mode of blood pressure goes up and energy is quickly made available in the blood. even if it isn't needed. in the long term that can cause health problems too high levels of sugar and liquids in the blood and hypertension can be precursors to cardiovascular disease sic windows are the only permanent solution to help us sleep soundly and to give our in a a gnome system some rest. even in our modern well there are some loud noises that are somewhat outdated warning system should respond to. when it comes to distinguishing between annoying and life threatening sounds. human evolution still has a long way to go. we've got something

listen closely. andrea garcia is getting ready for bed but 1st he setting up a gadget that will measure the noise levels in his room because it's going to be a noisy night while he's asleep he will be exposed to the noise of airplanes flying overhead. tonight it will be turkey plains tomorrow night 16. andre tries to sleep as best he can. he's in for a restless night. people who live near airports have to put up with a lot of noise often until late at night and then again from early in the morning we're. almost mental has spent 7 years studying what noise does to our bodies the cardiologist is especially interested in the noise of airplanes at night which many

people struggle with. the idea of studying aircraft noise at night is based on major studies that have shown clear link between insufficient or interrupted sleep and a greater risk of cardiovascular conditions so heart attacks strokes cardiac arrhythmias or cardiac insufficiency. could too much noise be the cause the next morning andrea garcia goes to the clinic to be examined the doctors use ultrasound to evaluate the blood flow through his arteries that will show how elastic they are as a result of his poor night's sleep his arteries are less flexible. because andrea was healthy his body will repair the damage but that isn't the case with everyone. when somebody say i have coronary heart disease for example and i'm exposed to aircraft noise at night then the condition of my arteries deteriorates on the phone then i have to assume that this noise related deterioration of my arteries will

lead to more heart attacks or cardiac arrhythmias heart failure and so on as for how to use them. so how come noise affects our blood vessels. that's something thomas mental has been investigating in mice when the rodents are exposed to the sound of airplanes their bodies produce more stress hormones they also suffer inflammation of the arteries because free radicals seen here in brown are formed in their cells. that you see in those. 200 garcia has now had a 2nd night of aircraft noise again he has not slept well. the cardiologist want to know whether his body has got used to the noise in which case his arteries all to be a little more flexible this time and less affected by his lack of sleep but the ultrasound shows the opposite to happen here i was confronted with.

we've discovered that once an individual has had exposure to noise at night the deterioration of the arteries is considerably worse the following night stick up in other words your blood vessels don't get used to the noise the damage inflicted on them is actually more pronounced. studies have shown that aircraft noise at nice not only damages blood vessels but also the brain causing it to age faster the doctors have discovered that memory and the ability to learn are impaired as a result. mice exposed to aircraft noise in this study for example were less able to remember where their rescue platform was in the water. the results of the study can be transferred to humans. we can start speaking of the point is we know that children who live near airports develop a learning ability and memory more slowly and we can get one for our research results explain the cause of this phenomenon very well. people constantly

exposed to noise at night are at increased risk of high blood pressure atrial fibrillation strokes and heart attacks depression can be another resulting factor the scientists are now working on a drug designed to reduce the harmful effects of noise in the body. even though getting a peaceful night's sleep on a regular basis would of course be the best medicine. well i do love my headphones i have to admit and many young people are wearing headphones all over the day this is a problem. this is a problem in fact that we have several young person's already showing some kind of hearing loss and this might be due to.
