to farms and destroy sides. what is the legacy of this wide spread races, depression, today? history. we need to talk about here, the stories, shadows of german colonialism, the last things in life on 12 minutes. then why try to preserve them or hold onto them? hello and welcome. i'm sorry because the body and you'll watching so many aspects of life, nature and austin, rounding with all of us. and maybe even the generation oft it us like this ancient . but nature is precious and it is less present

where all the boxes that i solved drawing up. i remember watching hundreds of them as this locked out of the roof, sky, human activities and habitat last are a few among the many to that that but face to which have also led to a decline in the numbers. a young man from india as desolate stage. overall, just con is working with an organization to get these bugs back into the sky. the colorful guides are everywhere, and god just con in january, millions of people fly them to celebrate mother's son got the the him do festival, that mocks the start of the holiday season. what is beautiful to look at though? can be very dangerous for books. that's when we bring that up, but i at the steps in front of rescue mission a lawyer. that'd be up your budget as a bird is with you. right? to take a home loan because we had on the 20, the building the 23 at old is working with the truck shop and organization in

chapel that specializes in the rescue and rehabilitation of injured boards and the wildlife. they also good. we have received a bird if you call from month it'll at about 5 kilometers from here. they said that a bird collapsed in the night and it is not able to fly during the winter months when thousands of my v 3 boards flock here hoping that it finds himself responding to many more because he has been working as a rescue volunteer for 7 years and is experienced in dealing with literally patients like this one go by the video did come here from yesterday. it's a pigeon who that has a deep got in its wing. and what am i going to do it by a mind to chinese mondor is used to fly many of the guides here. it's a string that's quoted without a gloss,

despite the bad it to use persist evidence like so. she often encountered incidents of boarding duties involving guide strings. yes, i gave you what a lot of total and then less on any house in that it was a tide. you know, i don't this region and um, it was full strong full of that. you can see the, the, the, what it on this i have taken the present and i've done this in the study and i've kept some fluids for the basic and see what the morning. so thanks to the new game the morning and the, this part. thank you. using the, for the use of the more custom cannot be card sign festival, the board rescue was to receive between 700 to 800 calls, hoping that it has been trained to deal with birds hum, buy a glass quoted guide strings. i stabbed them, either them would you be as good as when i joined i always thought how to handle a bug or if a bird is what i can do with you. if it's the only thing that on the lock will

because it's in pain with the men, doesn't understand what's going on. but again, what we need to cover its eyes. we use those to whole data. what's up with all this is also thought to new. i learned to use hand to join the check the them to got the shows of the, the new building did update. despite the board rescuers efforts, not every board injured by guide strings can be saved. the animal rights group speed that india says this staple string means and kills pauses of birds and will lead the kite string their minds and now is so strong that even a adult thoughts are flying in. so it would just wouldn't break. and then that will cause these horrible traumatic injuries. i believe there's some research being done . and so what time of the day is less likely it's goes back to be in jw it. but because roger's dawn is a massive pathway from my grocery bags, which saying huge numbers into it. so i would just ask people to consider the knock on effect to flying kites. so this time of the it was witnessing such

a hot breaking incident that inspired rule had to establish the board rescue and due back in 2003, i got hit with 40 quotes and i was writing on my opinion on the board which fell right in front of me and i couldn't help the board and the board died. so that time i started thing like, i think the board will, you know, come back to life, but it didn't. so i was really upset and i thought something has to be done for this. this is what i taught then by next year we started the school work, the boards and not only access to building the site festival city goal to is also putting even populations under pressure. the expansion of the concrete jungle is encroaching upon natural habitats, leaving boards with limited space for nesting and feeding. a decent report on the state of india as boards found around 60 percent of species are in decline. the trend is concerning because birds play a vital role in particularly cities,

we have had project loss on areas are being developed. houses are being constructed, big buildings are being, be constructed and of our development, the practice of such that they're actually driving the birds of a very database, very helpful in cross $188.00 and uh uh, they help us and controlling the populations of the insect song, so best song. so there are many birds for example locusts. if you look at the low cost, the low cost school, the state, the entire fields because of the fees. if you have birds that the feed on low cost, the damage caused by the lo, locust, b, kentoria by the birds also structure, save it,

saved more than $13000.00 birds dislike in any hospital. the theme forest assess is the patient's boons and determines whether surgery is necessary. once recovered, the birds are set free again on the lease check. so generally it's on a lease yet, so we generally check more tied. the board is lying. is it able to port? it's going it's arch exhibiting, it's an actually videos this bird of prey has already covered well and is now ready to leave it on the child's shut up. it's always a moving moment for the board rescue was to see one of their patients spread its wings, antique to the skies. again, the around a quarter of the water soil is degraded. among other things, this means that it's lax critically new to you and so that we need to go off, which one of these nutrients is fox sports, a chemical elements that the was,

is running out of. so how do we replenish it? was the answer lies in our new rigs that you had. that's right. find out fail, says a center of bones, dna and seats, 8000000000 people, phosphorus and essential element that sustains all life on earth. it's also in your p more than that later. but the vast majority of it goes to making fertilizer. why? because without it, we wouldn't be able to grow enough food. the problem is that there's a finite amount and roughly 70 percent of it comes from one place. the visual problem is that we're wasting most of what's already there. every individual is just throwing away it left the bread every day. for countries like india, which is 90 percent dependent on imports, the dwindling access could be alarming. plus phosphorus is also causing some massive algy issues. but if the world's food security depends on it, what can we do about the potential shortage with alternatives to we have and cut our own p. save us. thanks to

a german scientist boiling hundreds of gallons of urine in 1669. we found foss for us, the 15th element, and a periodic table from doc to use, trying to find out how to make any right. what is phosphorus? all organisms need fast persist 10, essential nutrients and an essential component of life. this is barbara k manager. she's a renown so scientist based in scottsboro and canada. it's part of our team. hey, it's hard as far south was concerned past, let beds. it's part of our, our and i today roughly 80 percent of the girls, phosphorus is use for agriculture because that's a structural component of cells. it's essential for cell division implant development. without enough of it plants or stunted and don't yield as much, we've been increasingly using these chemical fertilizers on farms since the post world to period. together with crap engineering, it spread the green revolution. the sun, massive increases in crop yields,

especially in the global south and places like india, n 1916, a less than production was like, yeah, it will be the median since last year. i would really like to production with step $315.00. and so jason, i'd like to share yeah. as a scientist at the engine institute as swale science. definitely. they give it's good. i think before close that application because before it was there was no knowledge about the world wide fertilizer use increase 6 times from 1950 to 2000. so where do we get all of it from? so to answer that question, we 1st need to show you the worth long as conveyor belt system, which can be seen from space. it's transporting the raw material phosphate rock from the blue cross line across the western sahara desert. roughly 70 percent of the growth reserves are in the western sahara, heavily disputed territory currently controlled by morocco, which the un size has been unlawfully occupying the area of rebel army has been

fighting for its independence. the largest reserves are spread across north africa, followed by china, brazil, south africa, and saudi arabia. the scarcity mix prices extremely volatile during the global financial crisis in 2008 shortage and foster as fertilizer shop prices up 500 percent and field riots and places like india, kenya, edge area unpackaged on fussy rock is a non renewable resource. and we can substitute it integrates for getting some, some scientists of one that we're approaching peak phosphorus. barbara seems to think otherwise. iris child seventies. i remember carlisle and yet have we actually reached the cloud with as a crisis now because it becomes economically feasible to find alternatives. in fact, less than 20 percent of the phosphorus used in agriculture actually ends up in the food beat. that's partly because phosphate fertilizers, notoriously inefficient. it binds easily with other minerals in the soil, which makes it unavailable for a plant. when they get 950 of costs for this,

you apply to this. it was do get, don't, they didn't get this from what people do yet as to what our body, but maybe 80 percent of that would be best if you didn't inside. that's why the industry solution is to check more on to the soil, faster suppressed, relatively cheap, adding a bit as good as the marble guarantee profits. this accumulative phosphorus is called the legacy phosphate. how much phosphorus is lost in the, sorry, i'll also depends on the c o p h to set up. so i can work climates and it will bind to iron and aluminum to alkaline. it'll react with calcium. but this has consequences. the use of chemical fertilizers increases the run off of nutrients like nitrogen and phosphorus into bodies of water. if it's huge, if occasion, which kills of oxygen, it also causes mass of alco bloom's, which can be toxic and produced 1st warming nothing when they die. contaminated water is lagging through southwest providers. shores. and francisco bay area is

experiencing a toxic eligible. and it's not just the waste from agriculture at this rampant fos versus everywhere in our food or tap water. and so if we consume a lot of it, then that means it's essentially what's coming out is the same. this is janice, done a call. she's of research or the swedish university of agricultural sciences and also started a company that turns urine and feces into fertilizer. one out of 10 people are like that in the amount of nutrients that are in urine as enough to grow as 500 grams of weight. so basically it means you're, you're and you can be grow. you can be producing a loaf of bread every day. she and her colleagues designed a system that essentially boils down her ex grid and retains its nutrients towel with the urine diverting toilet these toilets can get expensive and it leaves the problem at the individual consumer the agenda. so she's been approached by building

companies interested in installing them in new houses. and her company already has a partnership with swedish public toilet frontal firms. if we were to pre circulate of our year end and we could actually replaced 8 percent of the global demand of foster. unfortunately, household p is just a small fraction involved in nutritious waste on earth. there's also phosphorus and sludge and industrial wastewater. not to mention the newer from livestock and dairy farming, one of the most scalable solutions is to figure out how to get all of that out and reuse it right now, so its treatment plans to get the water cleaner, get it. we're not looking at it as extracting we as are serenity is mining resources, but why not the industry? so figuring out how to improve existing technologies to make large scale removal economically viable. there's also been advancements and methods of extracting phosphorus from animal manure. there's no shark technologies, it's just right now,

it's still more cost effective to ship product from that it is to try to get it from all these other sources. we can also start earlier in the process and health plans absorb more phosphorous. recent research has shown that certain types of fund guy induct syria could be used in the future to improve crossfield and soil health in find j. did these other estimates group of funds a bit of like very good uh, fox sort of categories and it can extend that high cm scab inch. uh uh for us, for those from videos. it's not just an old scientist. they're still researching how these microbes could be used for large scale farming. however, transitioning to such organic agriculture takes time and could result in your bosses. risk. farmers are hesitant to take with the legislation could help move the market along. the you recently legalize the scale of phosphorus recovered from slides as fertilizer, and is working on laws that will require more of us for us to be removed from

wastewater. space is actually quite easy to recycle. the government of the 2nd says, hey, you have to recycle 15 percent of that process. that's been your wastewater. and then innovations finally have a chance to come to light it and start the implement. frankly, the cost of it is going to drive a lot of innovation when it was chief thought value that's i add up to best a kept at that. maybe i'm to stop mr. conf general, but based type stuff. i technician that fits there for talking about it and maybe it will trigger the p revolution dump. the odds are not just a problem, wiley exist, but they continue. it'll be a problem even yours after they're gone, broke 6 substances legion to the ground. i'm almost completely destroyed, but there is a group of women in the southern individual summit lotto, we're not just cleaning up these dump yards, but also reclaiming the land and turning it into something beautiful.

until a few years ago, this was just about in wasteland. now it's a beautiful garden. we are in a residential area impede, i'm either on the eastern edge of gwen but dude in southern india, the garden was created by danny moody moving, come on. she moved to the area so that her daughter is good study here to find the balance of the money and not in these places exactly opposite my house. it was just used as a dump yard just uh, when i asked people about it. and they said it had been like this for 36 or 37 years ago cuz they even found it quite scary to walk past the spot. and a lot of the good buy am, although you do qual, i'm thinking of money on this one. the one who most inspired her to address the problem was her mental c r. so i mean, not to the former c, e o of gwen, but it was b s, g college. he supported her idea right from the start but they

within order, but within 20 days he passed away in the state of his words urging me to change this place seemed my determination to know what i know and to turn in her 1st step was to do some research, it soon became clear that the land was a so called reservation owned by the state. such it is often live raised and quickly become a dumping ground. duncan, i wonder if people start dumping garbage some that it's hard to stop them. so many what against me. okay. did randomly let me go to iris valid beaten long. they were just waiting for me to face, but i took it as a challenge to go to challenging out on the a, danny moody moving komatt phased a lot of that data before she could get permission to redesign the area. after that, it took just a few months to transform the wasteland into a garden and her neighbors love it. the less but thing

the one plus about the garden is that the flowers have drag different but ideas off butterfly on the good maybe. but also there are 6, that's not a bit better. so the kid slow coming here, they call it the duck box. this box stands out as everything is integrated here because of the matter. it's entirely different from other children's boxes of a tube and spot thing either on the model autumn initially. before you go to see what displace would become either block or whatever. okay, let me run it to name of henry is determination and hardware cuz changed it into a beautiful garden and then the one of my kids come to put on. yeah. there are many on use reserve areas including but do that belong to the state that embody move and come on has now been commissioned to turn them into box to any other than the sites in the modem. any residential areas in going but don't have fox that are not maintained people in those areas who didn't read for cooperation. so in jews or even some strangers to take action,

presidents to join forces and change the place that would benefit that entire. so that would be a lot of the, let me use logical ones then embody moving composite daughters have finished the studies she, most of it again, her hope is that local residues will then continue to maintain the garden from a garbage dump. let's head to one of the most scenic cities in the world, which has been celebrated in hollywood bollywood and was sent him off for decades. the romantic city of wenus, but as the world heats, unless she has met the future of this, the d seems shaky. more and more of the city is sinking, each bossing the and it is becoming a big challenge to keep the city afloat. venice has fascinated the world for over 1600 years. and for just as long people have been scared of floods or worried that the city could sink into the sea. this is the latest attempt to

protect venice. 78 metal barriers that can be raised to separate the sea from the laguna. the system is called mos at signalfx triple symbol. if we hadn't had mos, the dentist would have been irreparably destroyed on november 22nd over 2022. it was the 2nd highest flood in history called, but nothing happened. we were able to protect the lagoon and venice of del, provide long ebony, so, or elizabeth to spits has already given the order to raise the barriers over 50 times, less to compare, search, see, and she's having to do with increasingly frequently. so the jeanette authority the most that we now know that mostly is a flexible instrument that does not always have to be opened and nor at the same time, sec danville. so today we know much more about the blacks and winds. so we're in a position to act again for flooding that out within 50 has the most a system only partially to guarantee the exchange of water between the sea. the

goons come very easy to go for the amount of them. does that mean venice can be saved? climate experts predict that the sea level could rise by 60 centimeters by the end of the century. the oceanographer gate arc when the keys and says that most it is just buying time. the most house and his moves enough to see fence game, a man, yes. at the moment seen so definitely in the next 1020 or 30 years. but if the sea level rises by 50 centimeters, and it will have to be used 300 to 400 times pass once a day 1st, i mean it won't manage to shop and moves, it won't be able to cool as a structure. but nor will the lagoon manage it because it meets the exchange of water. uh, did i won't it? but often house gosh, marco single vinny from the venice institute of marine sciences is researching the lagoons ecosystem. he says the frequency with which most

a is being used has not yet had any major consequences. but this could change if the lagoon is separated from the sea more frequently and for longer periods of time of the remainder of the time. okay, so um it's a sort of st. couldn't be that at some point we'll have to decide whether it makes sense to maintain the lagoon as a salt water lagoon or not that room for see the long closures interrupt the cycle between the sea and the lagoon. which is fundamental for venice, and we're also open to them. you know, it's what creates the lagoon floors open, which determines what plants and animals can live there. advocate. we're going to face talk decisions because they could understand the future whether to save the lagoon or the city the nations would ideally keep both the san marco is the lowest point of venice and the 1st applied work is currently under way to raise the square

the i'm going to my buddy now were raised to a $110.00 centimeters in the square would no longer be under water because it would manage up to a 110 centimeter with like flooding. and that over a $110.00 centimeters come and most of system would close, you may never read them. so in other words, there will be no more flooding on the san marcos. he believes we need to have faith that people often forget that venice has sunk 30 centimeters in the past 150 years . too much ground water has been pumped from the cities aquifers. but ground water could also help save the city from disaster response that it's not on the water. the stream pump coat is pumped up by the end in venice could rise by 30 centimeters again. to start asking, you'd be the exact, the 30 centimeters that we've lost in the past a 150 years. so the one i'm going to, let's move it up so we will be going back the button, the starting at 0 again, so to speak, for most of us are he says that venice,

as we know it cannot last forever. in any case. at some point the lagoon will have to be separated from the sea and the venetians will be forced to decide what kind of buy those cannot be rescued. we have to decide what to save some vent investments. there is only one, ben and, and it keeps my, i'm been in a difficult decision. one venetians hope they will never have to make or was without doing this. like i said at the beginning of this episode, some things are just too precious to. let's cool. what is threatening the nature around you when? what do you think can be done to preserve it? let us know. you can email us or reach out to me directly on my social media handles. i will see you next week until then. take care. good bye. so most gosh,

the, the, the,

the, the islands along the river are home to the challenges of bangladesh. every 6 months they're landed by title way. or the funny does actually be the last few. but peter, we don't funny. the latest populated stuff to do is give you the most a never ending cycle of destruction and rebuilding the in 15 minutes on d. w. they are abducted with promises, vacation,

ukrainian, children, but they find no safety in russia. the rest of the cation, the children are forced to live with new families. under moscow's watchful lines, stolen by russian snows. in 90 minutes on d. w. the west page. now i know i might just do it and i'm hoping dw newport fast thank strength. the mills join us as we travel around your and facing the history of every day of that. and that's something right around the wells. but no need to talk to that just to

subscribe already. listen to paul. gosh, that will take you along to the right to kid jackie is changing 6 years ago. we said it can't get anyone else to, but it does guardians of truth. this time, excel gen liz, turned into our meets the voices of the 3 turkey alter as the other one had to flee into exile. i knew the police would search my house. courageous people are trying to stem the turkish governments all sort of tammy and cools. of some kids, but really it's a crime is addressed in the past of trying to teach this phone civility for his action. what about freedom of the price and freedom of expression. guardians of tree tops, march 2nd on d, w. the

. this is the, the news coming to line from berlin. un security council moves to force and in to the fighting and guns up. but the us blocks the resolution calling for an immediate truce as china and other nations criticize us. me to washington proposes its own ceasefire resolution for the 1st time. also coming up the death of this event alex into buying the prompt to you leaders to consider new steps to punish the kremlin. we look at the previous whether previous sanctions or slowing rushes economy and honoring the giants of the sill.
