information on our website to be found at d. w dot com. ah ah. ocean's a one of the most important and an elementary part of life on what they stabilize our climate system and spoke 50 times more greenhouse gases than the atmosphere. in fact, they are the most important goblin sink on our planet. they're also home to hundreds of thousands of marine species with saliva is crucial to our life or none on equal in yesterday. let's talk about what's being done to take care of fido shots. hello and welcome. i'm some of that uncle. for our 1st story, we don't go very far, just a few kilometers from here in will buy marine life and especially coral colonies.

sure. are threatened by pollution and environmental degradation. a collective of young marine activists is working to create awareness and safeguard the city's coastline. number is known for being india's financial cup of tea for its beat, friends, and densely populated discreet. but when the tides received from its shoreline, every day, the real part of the city you that only a few of its residents have ever seen. t this, this been things you can see. basically, these are, it's got suzanne once nicholas lyrics, okay. locally coil blocks in it. yeah. plenty of them are there. and one died in m this males where you can see it. for a deep petard is a city who teaches water sports on the side. he started coming out in 2018 book and

camera in hand to walk the shoreline. oh wow. where is it? place was, oh, maybe julie julie now because that by that he's not being involved and are distorted, pretty serendipitously for him. one day when i was scanning fisherman's name, i got to see you and see haws in fisherman's, nate, and dang it. stay a small animal lake 3 inches long. it was very close though. sure. i don't find it because from our shores, who are not even blame and i was laid sap at a so much of life every there quarters wanted to see vans spawn. yes, it's late. i bought it in 2018. put out his daughter documenting the cost to de dozens of volunteers walked with him and 4 other members of his group now called maureen life. mom,

by looking for vide live that has so far remained largely unseen. one member of the group song, mike uses photography to reveal the ecosystem. he has photographed new, the bronze coroner's sauntered octopuses in the starfish among other small to microscopic species. year the team has set up an organization called coastal conservation foundation. and along with other members like shown at mahdi, the goal is to secure legal protection for the species the document we have along with the wall for protecting light. we don't even know what exist till so we go from shore brochure during lot aides. what that does is basically builds a baseline formation of all the money and our city of the city. we really want other people to make use of the data that we're collecting. in fact, we will have a very fancy students. we're doing a dissertation, have use our data, and it has been used in news articles in the court. what we want is multiple people

to provide data to the database and what every stakeholder to make use of it, including the government and natalie's. while this community works above water, another resident of mom buy goes under 23 year old, a scuba diver, a we the boob has a similar love story with the ocean. and the idea for me was to go and explore what exactly alum miss fees of the ocean. i am not able to comprehend living in bon b, and i wanted to see mary in life. i wanted to see sharks, lan daddy's door, didn't lead all natural habitat bubner photographs, a coral reef, and the life around to just joke residence. what's down there? she then conduct workshops with locals, including fishing and other local communities. the hope is to mobilize people into standing up against pollution and see that god has been flowing into the ocean, destroying half dots. so i think for any community or for any individual to realize the importance of climate change, they really need to see what's happening. and because the oceans are so polluted in

bombay, they cannot seek oils down. they cannot see the marine life clearly and do, and you get more people about god, a life. what we do is we host workshops where we project beautiful images of gardens as well as many life and educate people that these things are there in the oceans. and they need to be protected because they are being threatened. so the and ideas the sped awareness to the level that they know that this beautiful movie life as a to you, i, nations actually impacting them and then therefore work towards saving it. the bit thread that all citizens groups are up against at the moment is a 1600000000 euro high. the project that is blown in this area. it was opposed in court, but the city authorities defended its viability and one, the case the court do has asked the city to cross look into coral life elsewhere, but people like google are concerned how that will affect the entire system because

don't survive. so go ahead as i the basic units off the median ford ecosystem, just lay plants on the basic unit of the land ecosystem and the land 14 surf. 5 potters die, the small officials are going to die as a result of that. and the larger fishes i'm going to die on the entire teen were born together and separately concerned citizens of them by our working in their own knishes to push the cause of by life and biodiversity in the city for my mission is to give the see if it's not being done right now, and i wanted to be done when we look at protection, when we look at the holidays, when you look at the location, it's done for thornton's leafy. why? because the ecological important whom, why i just lost me to make a lot of meaningful. have you studied a realism if you still feel that they are not important? and we're, we to decide what is important wanted. we may be limbo equal to someone read or

normal. i will, i will, my, my in is to have a more holistic vision for our shoreline and our to dig the team house documented to were 500 to small and virtually invisible. a species along one bicycles by drawing attention to give ready existence, the citizen warriors hoped on shore, valuable marine life can continue to fulfil its roar and moon blazoned, wymond. now safeguarding marine life is very commendable and the need of the hour. but sometimes we are faced with difficult choices. for example, when extracting rare resources from the seat that could enable a more sustainable energy supply. manganese nodules are one such case. they contain valuable metals that can be used in batteries, e, carves,

and solar panels. but is the deep sea mining of these nod youth? environmentally friendly? let's find out. co, bolts, copper, and nickle their own was a known as transition metals. they're all around us. and yet a considered rare elements. we need them to make batteries, smartphone, laptops, electric cars, photovoltaic systems, and other types of power storage. the extractable amounts of copper, cobalt and nickel is very limited. these results is could soon be exhausted. that's especially true of cobalt. it's estimate said that the global demand for it could double by 2026. the largest cobalt reserves are in congo and australia, where it's often mind under a pooling working conditions. poly metallic nodules from the c bed could alleviate the problem. it's been estimated that they contain around

270000000 tons of nickel, 230000000 tons of copper and 50000000 tons of cobalt. oh, the nodules, a spread across large areas of the sea bed at a depth of between 3 and a half $1006.00 and a half 1000 meters. oh, in environments that have hardly been explored, poly metallic. no. jose grow very slowly and require a steady supply of oxygen, as well as a constant stream of arc take deep water. just how those no jewels grow is a pretty complex process. but put in simple terms. it all starts with minute organic particles like shell splinters or fragment of shocks. tooth i've a millions of years. metallic compounds dissolved by the sea water accumulate

around those particles and grow about a centimeter every 1000000 years. until that the size of potatoes, or even cauliflower heads. the process of findings of pulling metallic nadia oh actually done by the challenge expedition. 1874. that's been a long long time. and they, they just brought up a few with towards where they took sediment samples on the interest of her. because nomics started really in the, in the seventy's. people found out that these metrics are in there and that, that's where it sparked more awful exploration happens. oh, so scientists and not the only ones interested in poly metallic nor jewels. a lot of companies are also came to extract and exploit them. deep sea mining advocates say procuring the nodules from the sea is more sustainable than conventional mining . no forests are destroyed and no mining galleries have to be built. there would be

no child, labor or toxic fumes. the no jewels could simply be collected from the sea bed, at least theoretically. but one of the problems engineers are facing is the high pressure present in the deep sea. no machines have been able to harvest the nor jose on the sea bed in a commercially viable way. yet, machines that look like vacuum cleaners currently being tested. other prototypes are also in development. the biggest concern is the impact this technology could have on marine wild life because it won't just be sucking up no jewels as it moves along the sea bed. so who makes the rules that govern the deep sea? it say you an organization called the international c bed, all sorority in 1994,

the e u and a 167 countries signed a multilateral agreement that regulates deep sea mining. so far, the sea bed authority has only approved licenses to research the poly metallic nodules, not mine them. a german research project has been studying the effects of deep sea mining for several years. the g o ma research center on the max planck institute for marine micro biology participated in the project. they discovered that the nodules play an important role for the c bed foreigner by providing a vital habitat for ah, we saw that a lot of these manganese nodules harris all shed for no sir, you have glass upon just i'm looking literally for example, to live. so you have long stalks and then you have a spawn main main body on top. and they really grow attached to the nozzles and

they can hold a deep species. the research project simulated the effects of deep sea mining in an area of a few square kilometers of sea bed. the dimensions of large scale commercial, deep sea mining would be vastly different. we're talking about a 1000 so correct. let me just being destroyed here. the made him pakistan in these areas, but biological active as own the top $5.00 to $10.00 centimeters of the today are completely wiped out and destroyed together with a follow up and the and it kind of off re colonization or recovery of the system for the soft sediment will take hundreds to thousands of years. many deep sea microorganisms and animals could be disturbed or destroyed by the

machines. even the relatively modest research project altered the environment. we figured out that after more than 25 years, the most of the parameters that were analyzed didn't recover fully. so you can expect that even the pod that might recover that is independent of the nodules that there was definitely be gone. will needs decatur to center is if it can recover, told the mining could even disrupt the oceans, complex food chains. so is there any way to make deep sea mining sustainable that is not sustainable because it's not re growing. very simple as that. i think we can already make up all online society if we want to accept this impact or not. it's a dynamic. if the deep sea, no jewels are off limits,

where will we find enough of the metals we need to produce clean energy? first, we can reuse what we already have by taking precious metals out of batteries and all the devices. several companies are already optimizing the recycling process. and we can reduce our consumption and use the devices that contain these precious metals much longer. another treasure is being retrieved from the oceans. in india, a stomach seek yukon bars a band from being sold in india because they are considered to be critically endangered. but fortune still pre on them while they're so important and what's being done to protect them. let's find out under these christine waters lies a strange creature that creating quite a stir. not only in the local fishing town of monday,

upon one of the sudden most of india, but all the way into the mainland and beyond to neighboring china. to see cucumber, this one can go up to 30 centimeters long. conservationists have been trying to study the marine animals seek your con. birth are called the other ones of the see just like how are 2 arms out of farmers? friend, the are seeker, gamma plays the role of earthworms in the sleep, which means um it helps to make the soil more for tile. and this is good for the see grasses and also other associated organisms that live on the c c floor. i. and even though what a column above, over the last 4 years local forest ridge officer, esthetician has taken on the role of protecting the c cucumber because of its important ecological vote. already a color will the sea cucumbers. excreta is alkaline in nature,

and so it neutralizes the increasing acidity on the sea surface. and as it neutralizes the coral reefs underneath, below are saved from the thread of bleaching. cynthia, when the coral reef is healthy, fish cross crabs and other creatures tribe around. if any body, so only if the sea cucumber tribes of yellow sea will there be fish in the sea for our future generations formerly either with the threat to the sea, cucumbers began when demand for them started soaring, mostly in china, dry t cucumber, known as batch the mare is a popular delicacy and also considered an aphrodisiac. as a result, porting in india has increased 13 fold over the last 5 years for the one i can. lynette a youth on the alone will again, while right now, lots of young people are involved in scribe when in big smugglers where misleading young people is saying that they would like only go to jail for 5 to 10 days. and then they would come out and, and the case would be trots frequently,

but 2 events campaigns conducted by the forest department. and we have reiterated that much of data. this is a highly dangerous act. the punishment is similar to the crime of hosting a tiger. and landing, or an elephant to lower punishment. get a gamma i think equal on a punishment. les the good. the see cucumber is listed under the wildlife protection act as a schedule one species, which means the punishment could go from fines of to lack trapeze. about 2000 euros up to jail tang the forest officials petrol. this area checking for the contraband, and also teaching people in the villages about the consequences of getting caught. some farmer porters have learned their lesson. we spoke to one who wishes to remain anonymous. toyota grandmother and i got canceled by the way, i once got caught by the on halting the told me that the punishment would be between 3 to 7 years. imprisonment. guessing by the elders in my community decided that it was wrong to do the sound when it illegally. and then i'm so we decided

that we would stick to catching fish, or crab limone. they, even if you gumble get caught in or natalie when we take them out and returned them to them, what doc nala are there that the non gaap bethany load, or that you know, that this hasn't been easy for the fishing community who have traditionally fish to proceed cucumbers for their own needs. the bow which came in 2001 has affected their livelihood. would have been regular. i'm even officious on only fish will see cucumbers at certain bill. yes or not all you're wrong. there could still some volume of jeep val divers from blue to cooper in the sun. today. miss mann, the and they are all the stronger armies. georgia every now and again, they were allowed to catch. oh, see, carlos they could sell god. we wonder google our just or 2 years there, which would buy them a recent amount of food. la, la dana and all right, i was, i bought them origin. it's a complex problem with the seat you cumber in the middle of it all. it forest

officers, lexitas, are able to protect the animals by keeping an eye out for poachers. the casa marine ecosystem has a better shot at surviving, and the local fishermen could get back their livelihoods or still areas of a sensitive ecosystems. fishing itself can have a negative impact on them. in spin, a group of wall into divers is trying to raise awareness about this problem and organize clean up expansions for the move metal and garbage from the c. shorts now did see horses, soft, corals, neptune grass, groupers and a wide variety of seaweed inhabit the mediterranean waters off more. seattle in southeastern spain, with 73 kilometers of coast in the biggest salt water lagoon in europe. it's a paradise for recreational fishing,

but many fishermen use lead thinkers. they can end up on the see bed where they pose a threat to marine life fung, i'm afraid castle them base. let's take the case of a fish feeding on algae growing on a piece of lead when that fish approaches and begins eating the algae. it also ingest, so lead amended. it becomes part of the marine food chain. the small fish me eaten by the bigger fish and so on. if you like me to let is pass from one to the other more until finally we as seafood consumers, wind up with that lead on our plate, ah unrest for plato. some fishers are starting to use alternative thinkers made of ceramic or think, but the un estimate some $640000.00 tons of fishing gear, including hazardous metals, still ends up in our oceans each year. to combat the problem, volunteers from hippocampus and organisation focused on the conservation of shorts

. now did see horses have launched the plume? boom project grumbling ish or ny there. boom boom is a project born after so many dives. eunice, where we saw so much rubbish made from metal whip as if he got from lead me that used in sport fishing and professional fishing. they bought the way big ha nets loaded with lead sinkers, for example. it had got a team ave debrel to remove the metals from the see. the project relies on a vast network of volunteer divers like fail x r i s head out. today he's joining a cleaning expedition, a couple of the puzzles, a seaside village in one of the most bio diverse areas in the mediterranean basin, balsamic. okay, global. we're going to collect lead from the sea floor, the marine wave sent hooks from fishing here. even even a little small pieces that settle on the bottom of it and get half buried that, oh,

let's see if we get lucky. with the help of metal detectors, divers can collect between $4.45 kilos of lead at each cleaning. the results are registered on a website that monitors their efforts since 2017, more than 14000 metal sinkers equivalent to one ton of lead have been removed from the mediterranean. but plume doesn't just remove the metal. it also contributes to the circular economy by giving it a 2nd life. thanks to public funds and private contributions. 200 containers had been distributed at diving sinners and yacht clubs along the coast. here all divers can deposit pieces they've salvaged. yeah, give a label to them what have bravo. we put the lead here government and then the

association collects it and takes it to the companies. we have an agreement with that they can recycle the metal so it can be used again in batteries. for example, hydro romo for what the dea has that if once the containers are full, the project coordinators bring them back to the heavy metals recovery center. to date, they've delivered more than 900 kilos for recycling. apart from lead other garbage such as plastic cans and glass is harming the marine ecosystem. normally, only divers see the damage 1st hand. so colombo members, also organized photo exhibitions to raise awareness and reveal the underwater reality. aiken, old, they're not shabby sheet. people who don't dive can imagine what is under water on it, but they don't really know week. so if we show them photos and explain to them the consequences of, of having garbage in the sea,

they become more aware. he dumped it. a shake on cynthia must in addition to encouraging the use of sustainable sinkers. global is working with governments to implement eco friendly marine policies. and it's appealing to all people to stop throwing trash into the see. ah, now it wouldn't be far fetched to save them the health of our planet depends on the health of its marine, life. life on earth began in our oceans, and it falls upon identity from to make sure we protect it. think about that and i'll see you again next week from what entirety. good bye. and thanks for watching . ah . with

in good shape. have you ever smelled a feeling with joy and st.

john to shop in your in good shape. now. oh d w. this 10 story pyramid made up of a 100 people. is a cadillac tradition known as a s l. what appears to be a breathtaking climbing exercise? actually it hears to a precise plan that his cells world championships, interrogation, not for the faint of heart oh, every day counts for us and for our planet.

global ideas is on its way to bring you more conservation. how do we make cds reader? how can we protect habitat, what to do with a ball our waste? we can make a difference by choosing smartness solutions over stains, said in our ways global ideas. the environmental series included $3000.00 on d, w, and online. and ah, we perceive our environment with our senses, but which sense we rely on most various studies show that culture and habitat implements which of our senses is most important for people in the english speaking world. it's site in iran.
