to fish and they might just mtv ocean. hello and welcome. i'm so i think everybody and you are watching the world wildlife organization tells us that's over the scene . begin, 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 on the test. but not all hope is lost, that our efforts being made to preserve our moving ecosystem. so less dive right in . building and boston festivals and the safe investment was like, do go from job or they've been going julia, a must have delicacy on the dining table is the shoes sausage, which is also popularly known as each months box is much desired specimen of the freshwater fish is long as disappearing from the what to us in and around the states of less than one. and this is also the story with several of the species. so what our solution focused active is doing about that find out in most of the

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 cut up at the bottom of the so much have a thing here and been gold grew up eating fish and rice on it. not a big gully, simply can't imagine life without fish. well think about me, you could see that we've been go least 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 says tons of fish, every d. scott, in nearby regions by fissures likes. the numbers was he has been making the living from the a timothy the for 35 years now. but his daily gach 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 from should keep an eye out. we get around half of what we used to. i get 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 quantity. it was a time when you would cost you a net and catch as much as a $100.00 kilos officially every day, one for school know what the $10.00 this is the river road runs to some of the most densely inhabited areas in the wood road and bridge and for stuff 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 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 sea, and we do only having the sunlight north and not the fish or the fishes 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 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 and probably stop by your car. so you guys can do that. however, some like subordinate service, what 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 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, even for cleaning. dr. meant the zillow 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 who will be both on official people can now fish again and be a seeing fish girl to the full size. same of the middle model going to a dock or a single cell, but in a sort of split the knew 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, labor. well, after we clean the river, i helped make

a lot of harm, a complex got that, or do me a lot of money. so you might say, well, i wasn't alone. i know a, the other families who profited to anybody because southerners loved further develop. this child 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 breeze again. and locals have even reintroduced fish species that used to swim in these waters before the but the active as knows, this is only the beginning. well, so if i start from the amount of bit of a will send, my 1st recommendation would be dredging, which one i will do then beginning up of what the highest total chain cost. when john todd 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 survival over the plan. it won't find extinguishing

a plan. they don't need to go southern outside us with the nose that the road will fully divide. comedy 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, 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, that you 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, 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 shops, 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 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 the offshore race worldwide. samuel, 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 last 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 buyouts, or filter theaters, they filter water and sketch particles in that water. so feet are 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 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 an agricultural run of some

fertilizers and can cause toxic algo blooms at high levels. by them is also felt in more than just chemicals. pilot projects are using them to cream, leaks 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 bit 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 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, right. so the 1000000000 oyster project which aims to restore 1000000000 oysters to new york's harbor by 2035. as the oyster rece 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. all last race 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 waves that pass 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. in muscles inside it per 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 directions 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 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, people 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. 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 from muscles and oysters can be used in

a circular way. how much that who we can use now that we can use that said patsy. all tiny town extra. he uses the lift, the shells. it should lead me to penny composed of them as building material. the shells also sequestered carbon by balance, 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 bivalves. old shelves 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 of 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 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 eco system, will also benefit in people on shore. we can expect a ton of fish that hector, so boisterous, to be added to the brain environment through a restoration prices. so why 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, always true to 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,

the reading 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 fix stops. but 111 from the cost of somebody logo has taken it upon herself to spread. a van is about as 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 v. i could not say 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 $6.00 to $15.00, macy's 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 is less to fetish, a dizzy a cause. regularly 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 it doesn't mean 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, they haven't cut off and i thought they said that they've never eaten that face. and they're always hesitant to try while longer. the vendors alone said these beeches 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 them, i think that's what we've been buying for the past 2 years at the fish market. mila

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, we might have some buttons want everyone to know. we are going to buy fish, one of the fish, what we've done, 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 deemed but some try to via the types of should i do this experiment? if you spell that one, just one that really does y'all could not and hold her thoughts is work closely with local fishes to keep track of cutting, beating cycles, and the availability of certain species. and 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 a sustainable fish they should ensure that not only does it meet the criteria being production being caught from sustainable efficient and it should also be in season 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, 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 us. hey, use is especially 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 their research.

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 get uh, but kinda 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 vehicle here that ever since i was little, it's thrill heat. i mean the desktop mainly because data like this 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 post 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. it's been able find the product, the must continue more. it's worrying scale because rising temperatures caused the water to expand and with that, leaving the sea level to rise, heat loves i think those key, i almost know that we can see this on the beach is 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 them. this part of the lovely medical my m k i b 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 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 dealers have you don't see it, but i'm still on my data in an american trade magazine and compare them to their own findings. got about the 2 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. especially the arctic is effected, 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 that as it will meet 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. so, and 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. pasquale 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 tangle hall. and that

hasn't been sold once. was it any kind of seafood that you saw? plenty, all kinds of tries, but it's almost disappearing. now. do i have to? so 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 air conditioning systems best fight climate change. research as an engineers are

developing sustainable cooling models for private households and city districts. they applies tend to is old wisdom about wind and weather, and combine it with bold ideas to create something new. tomorrow today. next, on d. w. will illegal immigration to the usa determined ways the american dental election on the one hand, some voters, the strong, motivated histories and ignorance. on the other hand, there was a lot of solidarity and the willingness to support one another trumps wall. in the border crisis, flows into, oh is on d w the,

how many platforms can you handle single tenuously without having the feeling that it's just too much you might see me. how much can we do simultaneously? multitasking these, the modern because if we do too much, we paid it all wrong. we messed things up, risking brain damage. so let's stop this self sabotage, humans and multitasking watch now on youtube. v. w documentary on the long voyage through the ocean. another humpback whales with a comp time to answer the human soul met johnny. but now the and it says it comes out of whales.

most of the ocean conservation tend to do or are full base. what did they look like? how did our ancestors live? what did they eat? researches canal, glean information from even tiny fragments it? boom. dna sequencing an artificial intelligence, have grown as important to the discipline as shovels and brushes. the join us on a trip to an archaeological dig in southern front, which is especially rich and where you story excites that 9 more this time around on dw science. so welcome to tomorrow. today he's.
