time the day our peers and rivals, which one dear and gold, to help smart nature, the more likes watching on youtube dw documentary, the dates around to fish, and they might just mtv ocean. hello and welcome. i've solved radi and you are watching the world wide life organization tells us that would seem to be and people across the world rely on cc. i'm this isn't a very good sign because to see i'm the food i both understand. but not all hope is lost, that our efforts being made to prism our moving ecosystem. so less dive right in.

building and boston festivals and the safe investment was like who got from job wasn't been going. julia, a must have delicacy on the dining table is too selfish, which is also popularly known as each month's box is much desired specimen of the freshwater fish. as long as disappearing from the what to us in the states of less than one. and this is also the story with several of this piece. so what else there is a full can active is doing about it. let's find out a must to get that one over starting to the dozens of the ideas of fish in such a fresh catch. and a good bargain is a daily tor, for many in gold caught up at the bottom only so much. it was a bringing here in bring gold grew up eating fish and rice on it. now i've been gully simply gone to imagine life without fish. will think about that, you could see that we've been goalies, eat fish, or some kind of sea food,

can at least one me almost every day. and in fact, the most hockey markets like these sell tons of fish. every d. scott, in nearby regions by fissures likes the numbers of us he has been making the living from the it's some of these are the for 35 years now. but his daily gach is no longer, but it used to be i did leave us off before the 2 thousands. we would find a lot to fish in these waters. i'm sure people will be good around half of what be used to. i can watch all kinds of fish and especially varieties of prone were found in abundance, and most of them in would be done to do. but it was even named after these prompts a quantity. it was a time when you would cost you a net and catch as much as a $100.00 kilos official every day one for school, for the $10.00 difference. that it runs through some of the most densely inhabited areas in the wood road and bridge infrastructure. and increased agricultural

activity are all partly to blame for choking that of a according to geographer, the budget that the who studies the effect of human action under the ecosystems, the term of d as in the dyess deep or somebody bought it was the thing sitting in the office, the media, and when there is no fish order flew that he body term would be only saw, devising the dollars to medias and it has become an hour. so, i mean, it was, you call it, you don't really. you don't even live nice. it is one channel, so i mean from the sea and we do only having the satellite north and not the fish or the fishers now mostly get the fish by beating them invisible. it isn't the knowledge that store fresh rain water during the month. so meanwhile, the remaining flow in the time of the is under threat from growing riverbank settlements. animal and human beast often ends up directly in that of a untreated sewage is one of the primary causes for the growth of an invasion of aquatic plant. the water highs and it can be produced as fast and stops fish of

oxygen in the water mazda the you have got to the point that fishing is dying out. as we of making the living people have migrated to put charges on them by not doing our job to make ends meet. 6 5, i think our school however, some likes about no service with the stain on and doing the best to divide the time with each of those who ologist is an activist in his spare time and regularly leads low goods on water hyacinth cleanup drugs. some 8000 members of the fishing community have joined forces to clean 12 kilometers on the cleanings i've been for. we're cleaning dr. mint, there's a little was able to see the sun for the 1st time in ages. know governor to vote can move again. i get the motion of the just speaking about that with them because i want this is an amazing and unique experience for me when he goes on to the official people can now fish again and we are seeing fish grow to the full size.

see why the data points, you know, some button to satisfy the new that to make this a long term success. she needed to find the sustainable be to handle the vegetation . they were moving from the to the so the set up a t fleming compost fits to process the highest didn't waste mixing in easily available. the nano leaves and cold on each bit can produce up to 40 keyboards of organic for the lives of every month. it is sold to families in the region who use it instead of chemical fertilizers. later on, after we clean the river, i helped make a lot of our me complex. got that or do me a lot of money seem up there and i wasn't alone. i know a, the other families who profited to anybody because the southerners love further develop. his childhood has proven infectious people from dozens of nearby villages have started their own teen up trays. spots of the time at the beginning to breathe

again and locos have even reintroduced deficiencies that used to swim in these waters before. but the active us knows this is only the beginning. well, so if i start from the amount of that of a will send, my 1st recommendation would be dredging, which one i will do then beginning up of what the highest chain cost when you, idaho toad, remove all encroachments for, for to the stop all the pollutants from temple homes and markets, and lastly, have a long term plan for the river, so they've already planned. it, won't that extinction a plan? if i need to go southern assets with the nose that the road will fully divide, become a. d is long, but already dozens of communities reaping the benefit that's come with conserving the source of life and livelihoods in the region. have you ever heard of them keystone species visa species that have

a disproportionately large inbox on the environment where they live off and also helping for the entire system together? like i said, we often find these as strong are also known as the engineers of the ecosystem. because then not only significant team one to 5, but also really if you have it as part of the species by forming g, i'm been able to knock, they also help minimize the facts of climate. let's find out how this oyster and these muscles along with scallops. and clamps are by valves. ocean creatures with 2 attached shells. fossil records place their age over 500000000 years old. ready before the dinosaurs and they are found everywhere, from the arctic to the antarctic. to the equator, they start out tiny floating to the water. the oysters and muscles attach themselves to an underwater surface to grow. well,

clams buried themselves in sand. they come in all different shapes and sizes too. they used to be so plentiful that they were given out is free bar snacks. but over fishing cost populations to decrease by 5 percent off shelby's race worldwide. samuel, heidi, either way did her ph. d on the history of oysters and muscles. we've had this extreme loss of a highly productive habitat, cyber. the places in the world. and people didn't even know that it had happened. the more we learned about how valuable they are to ecosystems, the more devastating this last because that's because they do some incredible stuff and all by hanging out in the water. ringback wherever they grow, they're busy cleaning. because the majority of buyouts are filter feeders. they filter water and sketch particles, things at the border. so feed on those particles, surrogate cats of research,

time muscles or controlling ecosystem of the great lakes in the united states. you can imagine a muscle sitting at the bottom of the lake, maybe in 200 with me, those depths. you imagine that what i call them 200 meters above the muscle. that's single muscle can cycle that column of water in a couple of hours. they use whatever particles they need to grow and excrete the rest in a form that bacteria on the bottom can break down. as you can see on the left, the filter chemicals necessary for plants and animal growth, phosphorus, and nitrogen. these chemicals are present in agricultural, run out from fertilizers and can cause toxic algo blooms are high levels. items also felt in more than just chemicals. pilot projects are using them to clean lakes and oceans of micro plastics. tiny plastic particles, hard to see and collect the bivalves, absorb the small ones, and larger particles are excreted in feces, which can then be taken out of the water. so we can use these animals to clean up

polluted water. but in a closed environment, they can alter the whole eco system. that's what the researchers discovered in the great lakes. the muscles are native to this area and have cleared the water of nutrients to well. it was quite a realization they figured out the muscles that live at the bottom of the lake have this much effect on the biology of the entirely in the open ocean. it's a different story here. muscles and oysters conform rece able to support whole eco systems. oysters are particularly good at this overtime. researchers grow bigger and bigger and they are very complex. katie motion works for the 1000000000 oyster project which aims to restore 1000000000 oysters to new york's harbor by 2035. as the oyster reese grow ocean plants attached to them, which attracts small fish and other animals to become

a nursery and a feeding ground for all different kinds of organize. and so hundreds of other species, fish, crafts, little, tiny, antique organisms will make their home. and on the way survey these reese also support of the larger animals. a study of new zealand muscle. reeves found over 10 times as many fishing of them and see horses have returned to the oysters in new york harbor. their benefits also extend beyond the structures themselves. lowest rates of doing is actually protecting the integrity of the world a h. i. system. when a powerful wave comes in from the ocean and hits an oyster reef, some of the energy is broken off and lost, meaning the ways that passed that re art is damaging near the shore. this protects fragile coastal eco systems like c grasses, which function of the nurseries for ocean animals. and as carbon sinks, less wave energy also means less coastal erosion. and these ecosystem benefits can

also come from farms if they're sustainably managed. the muscles inside in the system is very beneficial. most of the day works muscle farmers in south africa to make sure their operations are sustainable as possible. sustainable fishing practices. for example, trying to ensure that the minimize co interrogations and attendance protected species, muscles are hung from ropes suspended in the water. the animals could become trapped in with the ropes properly anchored. it's extremely red that this happens. the also trying to ensure that their muscle fox themselves going to have an impact on the basic heavy tests that people paint over in a closed environment like this day, excuse me, from the muscles could cover the ocean floor. so platforms are rotated to make sure they don't overwhelm ecosystems 5, all farms require no feet and no antibiotics as they get everything they need from

the water rope. chrome muscles have a carbon footprint of 0.25 kilograms per cubic. for comparison pieces around a 100 kilograms per kilo. out of the water 5, i'll go through a process called desperation. they're placing clean water to remove pollutants, dangers to human health. a micro plastics are harder to remember, but even if you don't eat shell fish, you could be consuming one credit card with micro plastic per week. and unlike other methods of food production, waste products for muscles and oysters can be used in a circular way, almost who we can use now, that we can use it says types of have a town extremely uses the lift the shells as it should lead me to penny composed of them as building material. the shells also sequestered carbon by bounds, pull it from the water and use it to grow their shops. crushed up the shelves can be added to concrete instead of limestone. but the best use for the shelves is the

simplest. growing more bivalves. old shells are often we used for farming, but can also go to restoration projects where the shellfish are left in the water instead of eating. these projects are springing up around the world from australia to new york city. this is where the oyster really shines every year and we're collecting oyster shell from new york carver restaurants. so we've collected almost 2000000 pounds or shell already. the shows are cleaned and placed in cages. we've always their cages are put into shipping containers that we've converted into a way to set oyster larva onto shell. add water from the harbor, then some larvae, and after a week their baby oysters the cages are then moved into the harbor. as the oyster re gross, it creates an ecosystem will also benefit in people on shore. we can expect a ton of fish that had the boisterous to be added to the brain environment through

a restoration prices. so one more bibles generally mean cleaner waters. the positive impact of muscles and oysters can be doubled through circular uses for their shops. and of all of them, wasters of the super heroes filtering, sheltering, protecting, and restoring. and that's why we should be doing everything we can to put more of them in our waters. the value of money unofficially, the 2nd ones too many fish are caught taekwan's and the reading population is depleting waste products. so then it can be a process known as the global efficient. these fishing specials may also the developers fish or to their life cycles. and for dr. mcgee and did use the availability of fix stops. but 111 from the poles to somebody, not who has taken it upon herself to spread a van is about this dangerous practice to ensure

a scene of the future for the fish. and for the occupation efficient children, the coastal communities of 10, a fishing net, stone up dozens of varieties of edible sea food, but only a small proportion of these find bios marine conservation is the vehicle that says this with tons of fish every day given that it's india, and it's a very bio diverse country. they're catching a lot of diverse fish. but in open markets, which are the primary target market. so they, they can sell it for a value the, the people out on the thing a very few species. people are eating maybe 6 store for spin spaces at the most in metro is even if they are close to the cities and all that. and what the fishermen not catching is close to a 100 different a bit of

a. so we're not talking about the endangered species, you're not talking with dollars in start those, all those things, only the fish or what a 100, they're catching people that only eating $6.00 to $15.00. so what happens to the rest? the rest is less to pettus did the drug, you know, these signs by use of the dead or dying fish showed on the beach if they're still alive, like the sea sneak, she helps them back into the sea. but for the most bought and sold, the dead fish is dumped back into the ocean at the time of the leading fish stocks in the area. this is a waste. fishes can ill afford 1000 me know the 30 minutes. a lot of people don't even know the names of most deficiencies . for example, they would never even know what the mean is. customers simply do not buy such

treatment. if we try to sell them efficient, they haven't cut off without a cop. they say that they've never eaten that fish and they're always has a do drive longer. then goes along that needs beach is complain that customers often ask for fish that is out of season or hot to come by and locally want us. i uh, let me go for the grab the brands. uh but uh this fish then uh, probably the mattress for the freight. yeah. i don't. they extend an invitation to another good. the bigger of a fish. so nice sentiment to this, what we've been buying for the past. yes. as much as the fish market milan comes across the in season for steam, who take him and what vehicle a fish walk in. basically, it's closer to when we can see that you should have might have and i think it's important for everyone to know. we are going to buy

fish ones, the fish will give them like i def, i are unique to species and official freshman id. so we used to be both, i'm will for the most common my feelings are in, but i'm try to of, by the types of to should i do this experiment if used for that one, just one that really does, he could not unto the searches, look closely with local fishes to keep track of cutting reading cycles and the availability of certain species. and so this is the most of that we provide to people on, on fish walks. so they can just look at this and identify which of the fish in season and when we give them the test to go out and identify sustainable fish, they should ensure that not only does it meet the, could i video be, but i shouldn't being caught from sustainable efficient and it should also be in caesar the be a could not, is confident that we created awareness and

a more adventure to spell it. consumers will develop a more diverse appetite. the bad use, the bounty of 10 ne shows and all the court says what gets measured gets managed a 70 to roy. man in spain has abided by this model for us. hey, use is especially devices to measure the temperature and the source content of the mediterranean sea, collecting the data that is used by fishermen to strategize. that's pushing expeditions and by scientists will there be such it's just after dawn. but jose pasquals is a man on a mission. he's heading out to see the 73 year old, collects weather data on land and in the water. i was upset about eunice. the moment i use these special through monitors that you can lower into the see get

uh back on in the process, you have to around 5 minutes of one glass. they flip over to spend display the temperature in the deep by now get on the amount of time to elect them. but i do like a, in this temperature for the past fall knows all about the sea and how to measure it for over half a century. the topography for and son of a fisher has pursued his hobby of the coast of the 13th in northeastern spring, weather permitting. he goes to see twice a week to document water temperatures in the mediterranean. is maybe that. me see, it's my life. that's my place. it's almost like a drug, a miracle here that ever since i was little, it's through while i hear that main desktop mainly because data like this didn't exist when i was 15 or 20 years old then. oh no idea that those they start having reached his 1st measuring point posts up lowers one of his devices. it shows

that at a depth of 30 meters, the water temperature is close to 16 degrees celsius. pascal says the sea surface has warmed by full degrees since he began taking measurements is but it will bind in for a couple of the must continue more, it's worrying escape because rising temperatures caused the water to expand. and with that, leaving the sea level to rise, he loves and take those key. i sound most new sounds like we can see this on the beach and i to spend the money here, the half a meter narrower ingle. i verify that the beach here has shrunk by 15 meters since 1993. did say that those was made out to go along with the temperature pascal measures the water, salt content, which has all the one on them. this part of the medical my m k. i the one of the pieces and put it providing vital info that fisherman, like a sophomore you have come to rely on and i still feel them. we had that lifestyle work as closely connected to this data. and one thing if we knew

a bit more about at all like he does, we'd be better fishers for sure why they walk in and say to you, i want them to quote as difficult as i used 50 is piano support. this deal. there are species of fish that can cope with the rising temperatures by myself, sort of the others that are used to warmer water, you know, now come up nor that from more southern areas like a style. and of course, the morales posts up past qual, meticulously notes, the coordinates and measurements. then at the local tourist info office, he transfers the data to a website used by scientists worldwide. the deal on our side of you is to get them access to all my data in american trade magazine and compare them to their own findings. got about this in the hour. they said now they know their satellite instruments are working correctly. so delete this with you and then correct. i mean pasquals collection of years of data has also made an impression in barcelona. at

the institute of maureen sciences, researchers probe how climate change effects plants and animals and humans especially the arctic is affected, says oceanographer jordy slot, but so is the mediterranean. and other than that, we're observing bigger changes on the water surface than in other seas around the world. and there are regions we called hot spots. and the mediterranean is one of them. you know, the new squalls, how the it has grown and important in this era of climate change, which is why it's his mission to keep taking measurements and do his bit to slow down global warming the glen, able to get away. so, and it's painful because it's not a natural process or something, you can see how everything's changed or how the and how we're changing it and

everything is interconnected. part of the i'll even if only a small part becomes the stable on every things thrown out of balance. with all the full set, pasquals has no children, but hopes to find someone to carry on his legacy. still, she plans to keep going out to sea and conducting his measurements, for as long as he can the next time you think of ordering fission to a fish dry, tangled hall, and that hasn't been so once was at any time a sea food that you saw plenty alt advertise, but it's almost disappearing now. do as as know, you can email also. he talked to me directly on my case, and i will see you next week and then take care. goodbye the

the, the

ice cold. jessica needs an expedition ventures onto places that no one has to why is the ice melting more rapidly? in the ice fields. and past the 1st few minutes, d, w, now we are being chased and they are falling out of people that we have to be very

fast check. when you have reception please, we might have the zip code for environmental as are on the run from the to the mass . yeah. the illegal simba trade is a 1000000000 dollar business with no regard for people or nature in 75 minutes on d w the the good i wish i could have done more to save. you just click away, find the best document on you to really see the world as he's never seen it before,

the drive now to dw, talking into the race as long begun later, when we look back, we recognized at all, that's the moment when everything change. it's all about tillman and in the age of artificial intelligence, in 5 years is going to literally be china. the us, or who will control the technology that will shape the future of humanity. we may only find out, you know what the harms and, and malign uses as a weapon against democracy or when it is too small. it's new world z a i race starts march 16th on dw, the

. this is dana winters long from berlin. nikki haley drops out of the us presidential race. the former south carolina governor ends her band for the white house after losses to donald trump and into his day's primaries. that doesn't mean shall endorse the only republican now less than the race. also coming up as the 0 pain, assembly plant near berlin grinds to a halt. police plane are sent a far left relative group claims to be behind the attempt. and will these huge puppies put you out of a job. we talked to an a, an expert who explains how a new form of artificial intelligence is pushing the envelope and performing task,

but entertain us.
