i know the us or europe to control the technology that will shape the future of humanity, the small, it's new world, the a i race starts march 16th on dw, the dates around to fish, and they might just mtv ocean. hello and welcome. i'm sorry. got the body and you all are watching the world why life organization tells us that over 3000000 people across the world rely on cc. i'm this isn't a very good sign because to see i'm the food i vote on the tech. but not all hope is lost that our efforts being made because um i'm moving ecosystem. so less dive

right in. the building and boston festivals in the state of investment was like do golf foods all or they've been going. julia must have delicacy on the dining table is too selfish, which is also popularly known as each months box is much desired specimen of the specialist. the fish is long as disappearing from the what to us in and around the state. the rest and i'm, this is also the story with several other species. so what else there's a full can active is doing about it. let's find out. it must be sorting to the dozens of the ideas of fish in such a fresh catch. and a good bargain is a daily drawer 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 can't imagine life without fish. will think about me. 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 pocket pockets like these says tons of fish. every d scott in nearby regions by fishers likes the numbers of us. he has been making the living from the h. i'm at the end of a for 35 years now. but his daily gach is no longer what it used to be on the we was all before the 2 thousands we would find a lot to fish in these waters. since you keep an eye out, we get around half of what we used to. i can watch all kinds of fish and especially varieties of prone were found in abundance of the day. but it was even named after these prompt a final. it was a time when you would cost you a net and catch as much as a $100.00 kilos official every day. one 1st, you know, why pay a $10.00 fee? this is that a board runs through some of the most densely inhabited areas in the wood road and bridge and for stuck to and increased agricultural activity are all partly to blame

for joking that of a according to geographer, the budget that the who studies be effective human action under the ecosystems, the term of d, as in the dias, date of somebody bought it was the things thing in the upstream media. and when there is no fish order flew that evaluates whom would be only saw, devising the dollars to medias. and it has become an hour, so i'm going to let you call the duct identity. english. you don't even live me. it is $110.00 is arming 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 months 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 the untreated sewage is one of the primary causes for the growth of an invasive aquatic plant. the water

hyacinth. it reproduces fast and stops fish of oxygen into water mazda the we have got to the point. the fishing is dying out. as we is making the living . people have migrated to put charges on them by and are doing our job to make ends meet $35.00. if i buy a car, i think our school buses, however, some like subordinate service with the stain on and doing the best to divide the time with each of those who all are just as an activist in his spare times and regularly leads locals on water hyacinth clean up drugs, some 8000 members of the fishing community have joined forces to clean 12 kilometers on the cleanings or even 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 deficient. people can now fish again and we are seeing fish growth to the full size. so you

want to move all the way to a dock or a single cell button to satisfy the new that to make this a long term success. he needed to find a sustainable rate to handle the vegetation. they were moving from that of a so the setup ac fleming compost fits to process the water hyacinth waste. mixing in easily available banana, leaves and cold on each bit can produce up to 40 keyboards of organic fertilizer every month. it is sold to families in the region who use it instead of chemical fertilizers of labor. well, after we clean the river, i helped make a lot of our me complex in that or do me a lot of money. see my bill and i wasn't alone. i know 80 other families who profited to anybody because southerners loved for the day of of his childhood has proven infectious people from dozens of nearby villages have started their own clean up trays. spots of the time at the beginning to breathe again. and locals

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 todd, remove all encroachments for, for to the stop all the pollutants from temple homes and markets. and lastly i have a long term plan for the river, so they've already planned it, won't that extinguishing a plan? if i need to go southern, most of us with the nose that the road will fully devise. comedy is long, but already dozens of communities are 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? these a 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 in fantasies as strong are also known as the engineers of the ecosystem. because then not only significantly more to 5, but also for the 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 before the dinosaurs. and they are found everywhere from the arctic to the antarctic. to the equator, they start out tiny, floating through the water. the oysters and muscles attached themselves to an

underwater surface to gravel walk lambs 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 of shelby's race was insane. law. heidi all the way did her ph. d. on the history of oysters and muscles. we've had this extreme loss of a highly productive habitat. so many 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 loss because that's because they do some incredible stuff and all by hanging out in the water wherever they grow, they're busy cleaning because the majority of by valves are filter feeders, they filled the water and sketch particles ends at the borders. so feed those particles,

surrogate cats of research to 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 meters depths. you imagine that what i call them 200 is meet us above the muscle. that's the 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. in 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 ego 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 deal ization. they figured out the muscles that live at the bottom of the lake have this much effect on the biology of the entirely in 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 the searchers grow bigger and bigger and they are very complex. katie motion to work for the 1000000000 oyster project, which aims to restore 1000000000 oysters to new york 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, benton 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 phishing 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 read, some of the energy is broken off and lost. meaning the ways that passed that re aren't as damaging near the shore. this project 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 eco system benefits can

also come from farms if they're sustainably managed. the muscles inside in the system is very beneficial, but most of the day works muscle farmers in south africa to make sure their operations are sustainable as possible sustainable fishing practices. uh, 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. this happens the also trying to ensure that their muscle fox themselves going to have an impact on the basic heavy tests that they will 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 amps go through a process called declaration. they're placing clean water to remove pollutants, dangers to human health. the 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 that said types of money to extra dd use as the lift the shells. it should lead me to penny composed of them as building material. the shells also sequester carbon by balance, pull it from the water, and use it to grow their shops crushed up the shows can be added to concrete instead of limestone. but the best use for the shelves is the simplest. growing

more by valves. 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. these are is, there cages are put into shipping containers that we've converted into a way to start 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 sure we can expect a ton of fish that had a boisterous to be added to the brain environment of 3 or restoration devices.

so are 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 and especially the 2nd one to many fish, encore, taekwan's, and the beating population is depleting waste products. so then it can be a process known as a global efficient. these fishing specials may also the developers, and they gave you fish or to their life cycles. and for dr. mcgee and did use the availability of fish stops. but one woman from the full seminar has taken it upon herself to spread a van. it's about this dangerous practice to ensure

a scene of the future for the fish and for the occupation of fishing 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 not 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 they, the people are only eating a very few species. people out eating maybe $6.00 to $15.00 me, she's at the most in metro's even if they're 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 in our talking with dollars in start those, all those things, only the little bit of fish over a 100. they're catching people that only eating 6 to 50. so what happens to this, the rest in lester perish, the dizzy arcada just regularly signs by use of the dead or dying fish showed on the beach. if they're still alive, like this, the sneak, she helps them back into the sea. but for the most part on so the dead fish is dumped back into the ocean at the time of depleting fish stocks and the area this is a waste fishes can ill afford it doesn't mean the 30 minutes. a lot of people don't even know the names of most efficiencies. for example, they would never even know what the mean is. customers simply do not buy such

treatment. if we try to sell them officially haven't cut off without a problem. they say that they've never eaten that fish, and it always has a duty to drive longer than those along that needs beach is complain that customers often ask for fish that is out of season or hot to come by and local. what us, i uh let me go for the crabs on the phones. uh but uh this fish then uh, probably the mattress for the freight. yeah, i don't. they extend an invitation to another good uh. take it off uh ish. so no experimenting. that's what we've been buying for the past. uh yes. as much as the push market milan comes across the in season for steam, who take him and what vehicle? a fish walk. and 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 the species and official freshman id. so usually will, some will for the most common my feelings are in but some like 2 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 of the phone. so this is the most of that we provide to people on i 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 criteria of being production being caught from sustainable efficient and it should also be in caesar. the vehicle is not as 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 or what says what gets measured gets managed a 70 to roy. man in spain has abided by this model for us. he uses his special devices to measure the temperature and the sized content of the mediterranean sea, collecting the data that is used by fishermen to strategize assessing expeditions and by scientists for that. he says 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 noticed that the moment i use these special through monitors that you can lower

into the c k. uh, but kinda in the process, you have to around 5 minutes of one glass. they flip over to spend display of 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 less 13 in northeastern spain. the weather permitting, he goes to see twice a week to document water temperatures in the mediterranean is maybe the receipts. 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 heat. i mean, it is time mainly because data like this didn't exist when i was 15 or 20 years old and no, 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 political funding 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 equal to the love's i think those key. i almost know that we can see this on the beach is like to spend the money a year. the half a meter narrower. i verified that the beach here has shrunk by 15 meters since 1990 . 3. 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. who am i the walk in the city? i want them to hold as difficult as i used 50 is piano supported on 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 squall meticulously notes. the coordinates and measurements then at the local tourist info office, he transfers the data to a website used by scientists worldwide is telling us have you don't get them access to all my data in an american trade magazine and compare them to their own findings that they see in the hour they said now they know their satellite instruments are working correctly. so delete this with you and then coordinate coming pasquals collection of years of data has also made an impression in barcelona. at the

institute of maureen sciences, researchers pro 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 as you know, there are regions we called hot spots and the mediterranean is one of them. you know that as it will meet the new pasquals, 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 generalize when of course it's painful because it's not a natural process or something. you can see how everything's changing, how the and how we're changing it and everything's interconnect just brought up.

the i'll, even if only a small part becomes the stable on every things thrown out of balance. to the full set, pasquals has no children, but hopes to find someone to carry on his legacy. still, he plans to keep going out to sea and conducting his measurements, for as long as he can, the to the next time you change the expression, tips of fish, dry tangle hall. and that hasn't been sold once. was it any kind of sea food that you saw? plenty, all kinds of tries, but it's almost disappearing. now. do that to so you can email us or he talk to me directly on my cell and i will see you next week and then take care goodbye. the
