to see a wide spread races, depression, today, the screen we need to talk about here, the stories, shadows of german colonialism, 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 globe. rely on cc. i'm this isn't a very was fine because to see i'm the food i both on the test 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 westwood was like,

do go from job or have been going julia. a must have delicacy on the dining table is the 2 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 what i'm, this is also the story with several of this piece. so what else is a full connective is doing about it? let's find out in most, starting 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 of the so much have a ring here in been 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 fucking markets like these sell tons of fish. every

d. scott, in nearby regions by fissures likes, the numbers was he has been making the living from the age. some of these are the for 35 years now. but his daily catch is no longer what it used to be. on the we was on the for the 2 thousands we would find a lot of fish in these water. some should keep an eye out. we get around half of what we used to. i can watch all kinds of fish and especially varieties of pran were found in abundance of the men will be done to do, but it was even named after these prompt 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 1st to know what the $10.00 this is that runs through some of the most densely inhabited areas in the wood road and bridge and for stuck to an 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 chum 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 li live nice. it is $110.00 is amin from the c. 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 that of a 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 you have got to the point. the fishing is dying out as a is making the living. people have migrated to put drugs on them by and are doing our job to make ends meet the cost, think our school develop. however, some like subordinate service, what the staying 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 low goes on water, highest and clean up drives some 8000 members of the fishing community have joined forces to clean 12 kilometers of 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 doing that because i want, this is an amazing and unique experience for me. when we go, the official people can now fish again and we're seeing fish girl to the full size . same of the middle model going to a dock or a single cell 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 removing from that of a so the setup ac. so let me compost fits to process the highest and 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. 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 see months ago and i wasn't alone. i know 80 other families profited to anybody because southerners loved further develop. his childhood has proven infectious people from dozens of nearby villages have started their own clean up trays. lots of the time of the are 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, to see and have a long term plan for the river survival go very plan. it will finding things in a plan. they don't need to go southern no service with the nose that the road will fully devise. comedy is long, but already dozens of communities already being 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 these 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 gretel, 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 the auction race was a little 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 the hanging out in the water wherever they grow, they're busy cleaning because the majority of buyouts are filter feeders. they sold the water and sketch particles ends at the borders. so feed on those particles, surrogate cats of research, time muscles are controlling the 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 of these chemicals are present in agricultural, run out from fertilizers and can cause toxic alco blooms at high levels. by them is 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 excluded and feast, 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 an 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 i work for the 1000000000 oyster project, which aims to store 1000000000 oysters to new york's harbor by 2035. as the oyster wreaths 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 organized on so hundreds of other

species fish crafts behind the bended organisms will make their home and always survey. these reese, also support of the larger animals, a study of new zealand muscle rece found over 10 times as many fish near them and see horses have returned to the oysters in new york harbor. their benefits also extended beyond the structures themselves. as always, to raise to join is actually protecting the integrity of the role, the h. i. system. when a powerful wave comes in from the ocean and hits an oyster, reese, some of the energy is broken off and lost, meaning the ways that passed that re art is 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 the system is very beneficial. most of the day works muscle farmers inside of 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. this happens the also trying to ensure that their muscle fox themselves cannot 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 and 0.25 kilograms per cubic. for comparison pieces around a 100 kilograms per kilo. out of the water by valves go through a process called declaration. 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 each of fish, you could be consuming one credit card with micro plastic per week. and unlike other methods of food direction, waste products from muscles and oysters can be used in a circular way. how much but who we can use now that we can use it says types of all tiny town extra. he uses the lift the shelves. it should be mico kenny composed of them as building material. the shells also sequester carbons 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 by valves old shelves are often were 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 we're collecting oyster shell from new york carver restaurants. so we've collected almost 2000000 pounds of shell already. the shows are cleaned and placed in cages. resource or 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 they are babysitters. the cages are then moved into the harbor. as the oyster reef grows, 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 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. foresters 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 one to many fish on contract. once the reading population is depleting waste products. so then it can be a process known as over fish. 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 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 fixed, this waste 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 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 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 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 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 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 fish,

and they're always hesitant to try longer. miss mendoza alone send these beaches, complains that customers often ask for fish that is out of season or hot to come by and local. want us. i uh, let me go for the grab the bronze. 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 2 years at the fish market. miller comes across the in season fish team 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. one of the fish focuses on like, identify, are unique to the species and official freshman id. so usually both i'm will for

the most common my feelings are in, but i'm try to via the types of things. should i do this experiment? if you spell that one, just one that really did you all could not unto the searches, look 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 we give them the test to go off and identify a sustainable efficient they should ensure that not only does it meet the idea 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,

they shows and or what says what gets measured gets managed a 70 to your role as man in spain has abided by this model for your hey use is especially devices to measure the temperature and the sort of 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 will look sort of back, eunice, go to get a 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 one glass. they flip over, if you spend display of the temperature in the deep by now get on the amount of time to elect them back to that guy 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, 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 here. i mean, there is time mainly because data like this didn't exist when i was 15 or 20 years old and no, no idea that that was based on having reached his 1st measuring point. posts up lower is one of his devices. it shows that at a depth of 30 meters,

the water temperature is close to 16 degrees celsius. past well says the sea surface has warmed by full degrees since he began taking measurements. its political funding for the government village, whatever they 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 lovely pick those key. i almost know that we can see this on the beach. you'd like to spend the money a year, the half a meter narrower ingle. 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 p 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 brothers 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. the zillow last time we had an issue with them and so on. my data in an american trade magazine and compare them to their own findings. that of the, the, the, 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 probe how climate change effects plants and animals and humans.

the, 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 call 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 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 or heavy 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. with all

that money. for step past qual 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 next time you're think of ordering fission tips or fish dry, tangled 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 we have to? so you can email us or he talk to me directly on my case. and i will see you next week and then take care. goodbye the

the most is a video and audio production by d w. i hope that you will tune in floating away when it's 40 degrees celsius and the shade can be deadly. during times of climate change, i asked workers what was the most difficult part of their job? uniformly, they spoke about sheet being most difficult part of their jobs. men described it as a feeling of drowning feats. sky was melting and you couldn't breathe. how do rising temperatures change from different parts of the world? in february, march 15th on dw, the,
