g, several shapes 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 somebody, and you are watching equal in 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 i'm the food i vote on the test. but not all hope is lost, that our efforts being made. the prism are moving equal system. so let's dive right in. the morning and boston festivals and the safe 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 much desired specimen of the freshwater fish is long as disappearing from the what to us in around the states of less than one. and this is also the story with several other species. so what our solution, fulton, active is doing about it. let's find out a must 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 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. will think of, you could see that we've been go least eat fish or some kind of sea food can at least one mean almost every day. and in fact, the most pockets markets like these sell tons of fish. every

d. scott, in nearby regions by fissures likes these numbers was he has been making the living from the age. some of these have uh for 35 years now. but his daily catch is no longer, but it used to be on the we was all before 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 bron were found in abundance of the men will be done to do, but it was even named after these prompt a find out. 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 why they are lovely. this is the runs to 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 joking,

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 official order flew that he body term 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 sea. and we do only having the sunlight 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 highs and it reproduces fast and stops fish of oxygen into water mazda

the you have got to the point. the fishing is dying out. as we 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 however, some like subordinate service with the staying on and doing the best to divide the time with each of those who ologist is an activist in his spare times and regularly leads low goods on water, highest and clean up drives. some $8000.00 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 he goes on deficient. people can now fish again and we have seen fish girl to the full size. same on the middle. all the way to a tough place, you know, somebody in the service,

but the knew that to make this a long term success, she needed to find the sustainable way to handle the vegetation. they were removing from that of a so the setup ac fleming compost fits to process the water high since 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. later on, after we clean the river, i helped make a lot of room a 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 southerners loved further develop. his childhood has proven infectious people from dozens of nearby villages have started their own clean up trace spots at the time of the beginning to breathe again. and low goes 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 the hotel would remove all encroachments for for to the stop all pollutants from temples, homes and markets, and lastly posts, and have a long term plan for the river survival to go over the plan. it will think seclusion of plan if i need to go southern a service with the knows that the road will fully divide, 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 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 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 the 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 about i was then on shelby's price. what was his name was heidi either way. did her ph. d on the history of oysters and muscles? we've had this extreme loss of 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 loss because that's because they do some incredible stuff . and all the hanging out in the water wherever they grow, their busy cleaning. because the majority of buyouts or filter feeders, they filter water and sketch particles ends at the borders so few, those particles, surrogate caps of research. time muscles are 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 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. the 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 an agricultural run of some fertilizers and can cause toxic algo blooms at 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 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 of 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 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, right. so the 1000000000 oyster project, which aims to store 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 organisms. so hundreds of other species fish, crafts, little tiny, bended 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, as always to raise to join 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 sea grass, it's 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, i didn't have actions and attendance protected species, muscles are hung from ropes suspended in the water. the animals could become trapped in to what the ropes, properly anchored. it's extremely red. this happens the also trying to ensure that the muscle fox themselves cannot have an impact on the basic heavy test 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, beef is around a 100 kilograms per kilo. out of the water 5, i'll just go through a process called desperation. they're placing clean water to remove pollutants, dangers to human health. 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 production, waste products from muscles and oysters can be used in a circular way, almost. but who we can use now that we can use it, said patsy. all paid to extra. he uses the lift, the shells it shouldn't make any composed of them as building material. the shells also sequestered carbon by balance, 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 shows 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, and 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're a baby oysters. the cages are then moved into the harbor. as the oyster read, gross, it creates an ecosystem. well also benefit in people on shore. we can expect a ton of fish that had a voice to read, to be added to the brain environment of 3 or restoration devices. so one more

bible is generally main 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 superheroes filtering, sheltering, protecting and restoring. that's why we should be doing everything we can to put more of them in our waters of the value of meridian, especially as a 2nd, went to many fish on port taekwan's and the reading population is depleting waste products. so then it can be a process known as over fish. these phishing 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 sustainable 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 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 they, they can sell it for a value. the, the people are only eating a very few species. people are eating maybe 6 store for spin 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 goals and start those,

all those things. only the fish over a 100, they're catching people that only eating 6 to 50. so what happens to this, the rest in lester perish or did the drag, you know these signs by use of 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 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 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 do drive longer than those alone that needs beaches complained 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 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. the bigger of a fish. so annoyed sentiment to this what we've been bank of 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 and visibly it's closer to when you can see that you should have might have some partners want everyone to know. yeah, them to buy fish ones, the fish will give them like i def, i 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 going to uh, by the types of to should i do this experiment? if you spell that one, just one that really does you all could not unto the thoughts is 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 of 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 this pushing expeditions. and by scientists for this, 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 looking at about eunice noticed that the moment i use these special through monitors that you can lower into the c k. uh by kind of in the process,

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 see that main desktop mainly because data like this. it didn't exist when i was 15 or 20 years old and no, no idea that those 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. 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 arrive equal to the lives they take those guys down. most know that we can see this on the beach is like to spend the money a year, the half a meter narrower ingle. i verify that the beach here has trunk 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 the front 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 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 city?

i want them to go to cisco and as i used 50 is piano support 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 dealers have you don't get them access to all 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 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. as you know, there are regions we called hot spots and the mediterranean is one of them. you know, the new squalls, how the it has grown in importance 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. to the

full set past qual 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 wonderful. is it any kind of sea food that you saw? plenty, all kinds of tries, but it's almost disappearing. now. do i just know you can email us or he talk to me directly on my shoulders and i will see you next week and then take care. goodbye. the
