i want is and what it represents, neither china nor the us are able to back down. and the rest of us are stuck watching the super power rivalry play out the dates around to fish, and they might just mtv ocean. hello and welcome. i'm sorry. got the body and you are watching the world why life organization tells us that would seem to be in people across the world rely on ceasing. and this isn't a very good sign because to see and the food i both understand. but not all hope is lost, that our efforts being made. the prism are moving equal system. so less dive right in. the morning and boston festivals in the state of investment was like do golf

food y'all, or they've been going. julia must have delicacy on the dining table is too selfish, which is also popularly known as each month's box. this much desire specimen of the freshwater fish is long as disappearing from the waters in around the state. the rest. and i'm, this is also the story with several of the species. so what else there's a full connective is doing about it. let's find out you must do something to the dozens of the ideas of fish in such a fresh catch. and a good bargain is a daily drawer for many in going 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. well, think about me. you could see that we've been goalies, get fish, or some kind of sea food can at least one mean almost every day. and in fact, it las pocket markets like these says tons of fish, every di,

got in nearby regions by fish shows like see them bits of us he has been making the living from the age. 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 water from shiki, but i'll be good around half of what we used to. i get lots, 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 for school, for the $10.00 difference. that runs to 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 body that the who studies be effective human action under the ecosystems, the chum of d, as in a dire state for somebody bought, it was the things thing in the upstream 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 to be coming. all are starting to legit call the duct all you, darlene lee? i'm sorry. 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 face or the fixtures. now mostly get the fish by beating them invisible. it isn't the knowledge that store fresh rainwater 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 the untreated sewage, as well as the primary causes for the growth of an invasion of aquatic plant, the water highest. and it reproduces fast and stops fish of oxygen. and what of the

mazda the we have got to the point that fishing is dying out. as a way of making the living people have migrated to put drugs on them by not doing our job to make ends meet, didn't call the 5. i think our school however, some likes about no service. what the sting on and doing the best to divide the time of the develop those wallet, just as an activist in his spare times and regularly leads low goods on water hyacinth cleanup drugs. some 8000 members of the fishing community have joined forces to clean clothes, kilometers on the liquid cleanings ivan 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 boat 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 we go from a deficient people can now fish again and we're seeing fish growth of that for the sites. so you want to move all the way into the into play a single cell,

but instead of split the new that to make this a long term success, she needed to find a sustainable be to handle the vegetation. they were removing from that of a so the set up a thief, let me compost fits to process the highest and waste mixing in easily available banana leaves and co done. 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. the well after we cleaned the river, i helped make a lot of our me complex. yeah. 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, what is so the sofas southerners love 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 of the are 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 then beginning up of what the highest chain costs when you all know, todd, remove all encroachments for for to the stop all pollutants from temple homes and markets, and lastly to see and have a long term plan for the river survival over the plan. it will think seclusion of plan. if i need to go southern, i said us what the knows that the road will fully divided, become at the 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 and fast on the environment where they live off and also

helping for the entire system together. like i said that you often find in fantasies as strong are also known as the engineers of the ecosystem. because they not only significantly modify 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 you may have found everywhere from the arctic to the antarctic, to the equator, the start out tiny, floating through the water. 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 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 i replaced, well, 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 wherever they grow, their busy cleaning. because the majority of buyouts, or filter theaters, they filled the water and sketch particles, things at the borders. so feed on those particles, surrogate cats of research to muscles or controlling eco system of the great lakes in the united states. you can imagine a muscle sitting at the bottom of the lake,

maybe in 200. if me those depths, you imagine that the want to call them to hundreds, meet us above that muscle. that 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 the 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 an 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 classics. 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 deal ization, they figured out the muscles that live up the bottom of the lake have this much effect on the biology was entirely in open ocean. it's a different story here. muscles and oysters can form re able to support whole eco systems. oysters are particularly good at this overtime. research has grow bigger and bigger, and they are very complex. katie motion. all right, so the 1000000000 oyster project which aims to restore 1000000000 oysters to new york harbor by 2035 as always, to rese 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 vented organisms will make their home and always 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 read, some of the energy is broken off and lost. meaning the ways that passed that re art is damaging near the shore. this protect 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. in muscles inside 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, i didn't have actions 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 thumbs themselves normally 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 feed and no antibiotics, they get everything they need from the water rope. chrome muscles have

a carbon footprint and 0.25 kilograms per cubic. for comparison, beef is 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. how much that who we can use now that we can use it, said patsy. all tiny town extremely uses the lift, the shells it should lead me to any composed of them as building material. the shells also is the cost of carbon 5 ounce pull up 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 bibles, 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 shelves are cleaned and placed in cages besides their cages are put into shipping containers that we've converted into um, a, a way to set waste or 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 reef grows, it creates an ecosystem. well also benefit in people on shore. we can expect a ton of fish that had a boisterous to be added to the brain environment 3 or restoration prices. so why more bibles generally mean cleaner waters?

the positive impact of muscles and oysters can be double through circular uses for their shops. and of all of them, or easters of the superheroes filtering sheltering, protecting and restoring. so 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 on podcast ones and the reading population is depleting waste products. so then it can be a process known as a global efficient these solutions that shows me also the developers, and they gave you fish ortho, 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 as dangerous practice in short, 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 bees find by us marine conservation is the echo dot 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 they, they can sell it for a value. the, the people are only eating a very few species. people out eating maybe $6.00 to $15.00 spaces at the most in metro's, 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 about those and start those, all those things. only they add a bit of fish over

a 100. they're catching people that only eating 6 to 50. so what happens to the rest? the rest in lester perish? did the arkansas drag, 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 part on so 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 resume. now there are 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 by substrate, but if we try to sell them officially, they haven't cut off. and i thought they said that they've never eaten that face

and they're always hesitant to try longer. mendoza? no, i'm saying these beach is complain that customers often ask for fish that is out of season or hot to come by and look at what us. i uh, let me go for the grab the phones. uh but uh this fish then uh, probably the mattress for the freight. yeah, i don't they experiment with fish, man. not a good the bigger of a fish. so no experimenting this what we've been bank of the past. 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 visibly it's closer to what you should avoid might have in partners want 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 say 2 of by the types of to should i do this experiment? if can you spell that one? just one that really did you all could not unto the searches, work closely with local fishes to keep track of cut and beating 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 the give them the test to go all the night into. if i uh, sustainable they should, they should ensure that not only does it meet the criteria being production 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 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 contents of the mediterranean sea, collecting the data that is used by fishermen to strategize. that's pushing expeditions and by scientists for their research. and 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 will look sort of back, eunice. noticed that the moment i use these special through monitors that you can lower into the c k. uh by kind of new apple 6,

you have to around 5 minutes of wine glass. they flip over, you spend display the temperature in the deep by now. get on the amount of time to elect them back to that guy in this step, roughly half 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 spring 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 vehicle here that ever since i was little, it's through while i he's, i mean to this type of mainly because data like this didn't exist when i was 15 or 20 years old, then no, no idea that those based on 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 probable 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 arrive with the lives and take those key. i almost know that we can see this on the beach is to spend the money layer, the half a meter narrower ingle. i verify 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 lovely 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 at that by star work as closely connected to this data. and one thing, if we know a bit more about at all, like he does, we'd be better fishers for sure. who am i the walk in city?

i want them to quote us discovered, as i use piteous piano support at this deal. there are species of fish that can't 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 task well meticulously notes, the coordinates and measurements. then at the local tourist info office, he transfers the data to a website used by scientists. worldwide. dealers have you don't have access to all my data in an 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 connect them in 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 there are regions we called hot spots. and the mediterranean is one of them. you know that it will meet 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 can do his bit to slow down global warming, the glen, able to get away. it's painful because it's not a natural process or something. you can see how everything's changed and how the and how we're changing it and everything's interconnect apart. up the i'll even if only a small part becomes the stable on every things thrown out of balance. 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 tips or fish, dry tangle hall. and that hasn't been so strong once. was it any time a sea food that you saw? plenty, all kinds of tries, but it's almost disappearing. now. do at this know you can email us or he talk to me directly on my shoulder and i will see you next week and then take care. goodbye the
