a global so this is a whole lot of climate problems to fix or is complement topics of pressure those channels. we've got new videos every friday tried to plan. it's a the dates around to fish and they might just mtv ocean hello and welcome. i'm so i think everybody and you all are watching the world why life organization tells us that's over the scene being people across the world rely on ceasing. and this isn't a very good sign because to see i'm the food i both understand. but not all hope is lost, that our efforts being made to prism are moving equal system. so less dive right in . the morning and boston festivals in the state of investment was like who got 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 is much desired specimen of the flash water. fish is long as disappearing from the water as 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 that find out in most, salting 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 it was a bringing 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 you could see that we've been goalies, get fish, or some kind of sea food can at least one me almost every day. and in fact the most

pockets markets like these sell tons of fish. every d scott, in nearby regions by fishers likes the numbers of us. he has been making the living from the a comedies of uh for 35 years now. but his daily catch is no longer, but it used to be on the we was uh before the 2 thousands we would find a lot of fish in these water. since you keep an eye out, we get around half of what we used to live your lot. all kinds of fish and especially varieties of pran were found in abundance, and most of the men will be down there too. but it was even named after these prompts 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, you know what the $10.00, this is the river road runs through some of the most densely inhabited areas in the woods 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 body,

that the who studies be effective human action under the ecosystems become a 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 flu, that e 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 our mean from the sea, and we do the 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 invasion of aquatic plant, the water hyacinth. it reproduces fast and stops fish of oxygen in the 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 going by and are doing our job to make ends meet $35.00. if i buy a car single school buses. however, some like subordinate service with the us being on and doing the best to divide the time and date of those who all are just as an activist in his spare time and regularly leads low goods on water hyacinth clean up traits some 8000 members of the fishing community have joined forces to clean clothes, kilometers of the cleanings i've been for. we're cleaning dr. mint. there's a little was able to see the sun for the 1st time in ages. no governor to boat 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 where we go from unofficial people can now fish again and we are seeing fish girl to the full size. so you want to move all the way into the into place, you know,

somebody to satisfy the new that to make this a long term success. she needed to find a sustainable way to handle the vegetation. they were moving from that of a so the set up a t 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. later on, after we clean the river, i helped make a lot of harm, a complex got that, or do me a lot of money. see my face and i wasn't alone. i know a, the other families who profited to southerners loved further develop. his childhood has proven infectious people from dozens of nearby villages have started their own teen up trays. spots of the time at 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 you, idaho toad remove all encroachments for for to the stop all pollutants from temple homes and markets, and lastly posts and have a long term plan for the river survival to go over the plan. it will finding things in the plan. if i need to go to southern assets with the nose 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, 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, we 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 buyouts. 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 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 off shelby's price. what was his main? well, heidi either way did her ph. d on the history of oysters and muscles. we've had this extreme loss of a highly productive habitat from 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, they're busy cleaning because the majority of buyouts are filter feeders. they filled the water and sketch particles and that water so feed those particles surrogate caps 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. if me those depths, you imagine that the want to call them to kind of 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. 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. these chemicals are present an agricultural run out from fertilizers and can cause toxic algo blooms of high levels. items also filtered 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. 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, the left of the bottom of the lake have this much effect on the biology. i was entirely in the 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, there's grow bigger and bigger and they are very complex. katie motion works with a 1000000000 oyster project which aims to store 1000000000 oysters to new york's harbor by 2030 thoughts 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 organized on. so hundreds of other species, fish, crafts, little tiny, antique organisms will make their home and always survey. these reese also support 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 by histories 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. but 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 interrogations in 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 the muscle fonts themselves in order 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 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 decoration. 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 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. but who we can use now, that we can use it said patsy. all tiny town extra 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 shells 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 because 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, will also benefit in people on sure we can expect a ton of fish that hector boisterous to be added to the brain environment through a 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, always true to the super heroes 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 unofficially, the 2nd ones too many fish are caught taekwan's and the reading population is depleting waste products. so then it can be a process known as the global efficient decisions that shows me also the developers fish or to their life cycles. and for dr. mcgee, and did use the availability of fixed on bus 111 from the poles to somebody, not who 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 efficient

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 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 markets that they can sell it for how you value the, the people out on the thing. 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 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 dogs

in start those, all those things, only the fish or what on it. 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 it doesn't mean now there are 30 minutes. a lot of people don't even know the names of most deficiencies. for example, they would never even know what the mean is. customers simply do not buy such treatment. if we try to sell them a fish, they haven't cut off the top, they say that they've never eaten that fish, and it always has

a do drive longer. then goes along that needs beach is complain 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 brands. 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 government to this, what we've been buying for the past. uh yes. as much as the push market, milan comes across the in season fish team who take him and what they call a fish walk. and basically it's closer to when you 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 both i'm well for

the most common my feelings are in, but i'm try to 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. 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 out and identify a sustainable fish, they should ensure that not only does it meet the good idea of 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,

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 salt 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 was upset about eunice. the moment i use these special through monitors that you can lower into the see get uh back on in the process. you have to around 5 minutes of one glass,

they flip over and display the temperature in the deep by now. get on the amount of time to elect them back to 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 the 13th in northeastern spring, weather permitting. he goes to see twice a week to document water temperatures in the mediterranean. is maybe that. me see, 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 thrill heat. i mean the desktop mainly because data like this, it didn't exist when i was 15 or 20 years old. then no, no idea that those facebook having reached his 1st measuring point posts up lower than 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 pretty cool, but then for a couple of the villas probably must continue more. it's worrying scale because rising temperatures caused the water to expand and without leaving the sea level to rise, he loves and take those key. i almost know that we can see this on the beach and i to spend the money here. 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 why they walk in city. i want them to hold as

difficult as i used piteous piano support on 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 past qual, 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 . 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 probe 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, 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 and do his bit to slow down global warming, the glen, able to generalize. we're not much, it's painful because it's not a natural process or something. you can see how everything's changing. i mean, 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. with all

the full set, pasquals has no children that helps 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 think of ordering fission to a fish dry, tangled haul, and that hasn't been sold once. what is it any time a sea food that you saw? plenty also advertise, but it's almost disappearing now. do as as know, you can email also. he talked to me directly on my case and i will see you next week and then take care. goodbye. the,
