ah, listen carefully. don't know how with this to the girl. ah, feel the magic discovery of the world around you. subscribe to d w documentary on youtube. with options are one of the most important and an elementary foss with life on the

stabilizer climate system and spoke a few times more greenhouse gases than the atmosphere. in fact, they are the most important goblins sink on our planet. they're also home to hundreds of thousands of marine species with saliva is crucial to our life on, on, on equal india today. let's talk about what's being done to pick carol fuddle shots . hello and welcome. i'm some of that for our 1st story. we don't go very far, just a few kilometers from here in we'll bite 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 school . slide number is known for being india's financial copy for its beat fronts and densely populated discreet. but when the tides recede from its show line every day,

the real a part of the city that only a few of its residents have ever seen. clear this, this being things you can see basically a desire 8 gaps, lose of one from the inquiry, lyrics ok locally called roxanne it. yet plenty of them are there. and one died in m this males. so you can see it for a deep petard is a sin who teaches water sports on the side. he started coming out in 2018 book and cameron hand to walk the shoreline. oh wow. where is it? place was, oh, maybe julie julie. now because the color is not pink. yeah, awesome. and 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, in dangling style. small animal lay 3 inches long. it was very close to though. sure. i don't find it because from our shores, who are not even going. and i was legs that are a so much of life every there who is wanting to see vans spawn. yes, it's late. i thought i'm it in 2018, put out his daughter documenting the coast to de dozens of volunteers walked with him and 4 other members of his group now called marine life mom, by looking for vital life that has so far remained largely unseen. one member of the group signing night uses photography to reveal the ecosystem. he has photographed new the bronze corals, zante, it's octopuses and 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 rule for predicting light. we don't even know what exist till so we go from shore brochure during lot aids. 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 a little recollecting. in fact, we will have a ride from 2 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 for 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 scuba diving a we the book has a similar love story with the ocean. and the idea for me was to go and explore what exactly other mysteries of the ocean that i am not able to comprehend. living in

bombay and i wanted to see mary in life. i wanted to see sharks land at east or do the lead on 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 that has been flowing into the ocean destroying habitat. so i think for any community or for any individual to release 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 either the down. they cannot see the marine life clearly. and do you get more people about god, a life? what we do is we host workshops where we project beautiful images of god 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 be and ideas the stead awareness to the level i've been without this beautiful moody life as

a to you. i, nations actually impacting members, therefore work towards saving it. the big thread that all citizens groups are up against at the moment is a 1600000000 euro highway project that is blown in this area. it was supposed 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 nonconsent, how that will affect the entire system if the cause don't survive. so god as i the basic units off the median foreign ecosystem, just a plant 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, concern citizens of them by are working in their own knishes to push to cause

a vine life. and biodiversity in the city for my mission is to give the see if you it's not being done right now. and i wanted to be done when we look at protection, when we look at the holidays and when you look at the location, it's done for sort in 3 feet. why? because the ecological important. oh, why i just lost me to like a lot of mean. what have you studied? are we others? we still feel that they are not important. and wor, we'll decide what is important wanted. we maybe being a little 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 on bicycles. by drawing attention to the ready existence, the citizen warriors hoped on shore, valuable marine life can continue to fulfil its role in mom,

buys environment. now safeguarding marine life is very commendable and the need of the hour. but sometimes we're 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 how boats, copper and nickel their own was a known as transition metals. they're all around us and yet 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 is 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 over millions of years. metallic compounds dissolved by the sea water accumulate around those particles and grow about to send to me to every 1000000 years until that the size of potatoes or even cauliflower heads. the 1st of findings of pulling metallic not yours are 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. of the interest of

her economists 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 looked 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 moved 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 social 4. no, sir, you have glass on just and then the letter would like 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 very 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 to hear the main and pakistan in these areas. they biological active. i us own the top $5.00 to $10.00 centimeters of the future. 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 micro organisms and animals could be disturbed or destroyed by the machines. even the relatively modest research project altered the environment. 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 2 centuries if it can be covered on the mining could even disrupt

the ocean's 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, stomach. seat yukon bars are banned 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. ah, under these christine waters lies a strange creature that's creating quite a stir. not only in the local fishing town of monta 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 a secret number plays the role of other ones in the seat, which means it helps to make the soil more fertile. and uh, this is good for the c glasses 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, looking for a strange officer as the thief has taken on the role of protecting the c cucumber because of its important ecological vote already a cali when 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 berlin are saved from the thread of bleaching when the coral reef is healthily 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 generation? this is what i'm really other with the threat to the sea. cucumbers began when

demand for them started soaring, mostly in china. dr. t cucumber, known as batch the mare is a popular delicacy and also considered an aphrodisiac. as a result, putting in india has increased 13 fold over the last 5 years with one i can larry, you'd wonder the loan will get more light. now, lots of young people are involved in the scribe when in big smugglers where misleading young people is saying that they would like only go to jail for $5.00 to $10.00 days. and then they come out on the and the case of detroit frequently. but 2 events campaigns conducted by the forest department and we have reiterated very much of that. and now this is a highly dangerous act. the punishment is similar to the crime of posting a tiger and an, or an elephant to lower punishment. get a gamma either equal on or punishment. les the gate to see cucumber is listed under the wildlife protection act as a scheduled one. species, which means the punishment could go from fines of to lactose peace,

about 2000 euros up to jail tank. 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. lou and again, whether anna got cancelled by the way, i once got caught on halting the told me that the punishment would be between 3 to 7 years imprisonment. case in 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 converse, get caught in on. natalie when it would take them out and returned them to the water nala, other than hung up and yellowed for that. you know, this hasn't been easy for the fishing community who have traditionally fish to proceed. cucumber for their own needs. the bow which came in 2001 has affected

their livelihood, would have been regular. i'm even a fishers. only fish will see cucumbers at certain bill. yes or not all you're running out of the good. a still survivor. there are divers from blue to cooper in the sun to damage with and they are all the stronger. i'm usually every now and again, they were allowed to catch. of course you can call us, they could sell got we wonder, groupon, our just or 2 years there, which would buy them a decent amount of food dollar. dana rang, i was up on the margin. it's a complex problem with the see cucumber in the middle of it all, it forest officers, lexitas. i 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 volunteers diverse 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 and the biggest salt water lagoon in europe. is a paradise for recreational fishing. but many fishermen use lead thinkers, they can end up on the sea 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 let me into it becomes part of the marine food chain. the small fish me

eaten by the bigger fish and so on, financial aid is passed from one to the other more quanto. finally, we as seafood consumers, wind up with that lead on our plate. ah, north plateau. some fishers are starting to use alternative sinkers 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, bruin 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 and without use and sport fishing and professional fishing. they bought the way big ha net loaded with lead sinkers, for example. it had category t my they,

they failed to remove the metals from the sea. the project relies on a vast network of volunteer divers, like phalanx, arleas haddocks. 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, do, and global, we're going to collect lead from the sea floor, the marine wave sent hooks from fishing. here you've only one, i will small pieces that settle on the bottom of it and get half buried. 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 had 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 have been distributed at diving sinners and yacht clubs along coast here. all divers can deposit pieces they've salvaged. uh huh. yeah, given everybody that was had global, we put the lead here government that them the association collects it and takes it to the companies. we have an agreement with us that they can recycle the metal so it can be used again in batteries. for example, admiral promo for what the dea has a diff. 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 organize photo exhibitions to raise awareness and reveal the underwater reality. it can also, they're not savvy sheet. people who don't dive can imagine what is under water honey, but they don't really know leak. 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, blue boom 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 defense 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 our entire team. good bye. and thanks for watching. ah ah, ah, with

who is the end of the pandemic in site. we show what it could look like. return to normal. and we visit those who are finding it difficult

with success in our weekly coping 19 special every thursday on d. w. ah, a mercy. when i arrived here, i slept with a single people in a room. 9th, in it was harsh. fair. i even got white hair is learning the german language help. yeah. a lot. this kids to me and great opportunity to interact with them. you want to know their story, my grants verifying and reliable information for my grants. a some people don't care about me because they don't see my beauty.

some people don't care about me because they think i have nothing to give. but 2000000000 people due to then i am every day at home, the food, their livelihood. but day by day i do. and so does everything i get to 1000000000 people care about me need me and now i need you. ah

ah ah, this is the w news live from berlin. dozens of russian missiles hit keys and other ukrainian cities. at least 11 people have been killed and dozens more injured. ukraine's president says russia is targeting.
