but also for the treating physicians and the medical system, etc, it's almost done. so minimizing false positives will be key to rolling out tests like these for wide scale uses a screening measure, a much larger study to see how gallery performs as a tool for early detection. is already underway in the u. k. and that's it for me and the news team for now up next is all doc film about the industrial x quotation of the ocean floor and the best mckinnon. and the news team will have another addition to the news for you at the top of the thanks for watching the prophets hearing, instead of response of the global business of asbestos. this is knowledge of the people that are in tongue deserve to be treated with any kind of courtesy by the governments of the world. the never ending story of asbestos

starts june 21st on d, w the the in the middle of the pacific ocean. an ambitious expedition has set taps to explore the deep sea going when no human has ever gone before. where a numerous deposits of minerals night dormant can humanity benefit from this on top, the source of wealth, the technology to harvest, it already exists. the 1st prototype of a deep sea collect to the treasured stones, this cold atanya. it's being tested at a depth of several 1000 meters, scientists and monitoring its deployments. because what is technically feasible

might actually destroy a delicate underwater wells. is it less the risk? this isn't them going to them. these are basically batteries in stone form. this is exactly what you need to build a battery. there's manganese nickel, cobalt and copper to conducts the electricity environmental protection organizations such as green piece one to prevent deep sea mining its own costs. the. it's the last cost of the planet that humans have yet to exploit for resources of the oceans in danger. the

making peace with nature is of the funding task of the century, preserving as restarting the ocean's ability to much of humanity and regulate all climates will be the defining challenges of these back at 71 percent of the surface is coverage by oceans. it's the neurologist habitat to on the planet the. the ocean says there's an important teach buffer and comp in sync. they observe about a quarter of mine made c o 2 emissions and thus mitigate the effects of climate change. the depth on need added on it or it's needs the oceans to survive. they regulate the climate they provide food,

they provide the oxygen, we bring more than 50 percent of it by the way and do things. but the world's oceans of suffering that ruthlessly being fished back the waste produced by an increasing the affluent society is becoming more president and the water virtually indestructible plastic waste in dangerous animals. and the habitats so called ocean dead zone. so guessing as a logic climate change is also causing sea levels to rise. never the last it's exploitation continues, sand and gravel of being dredged for uses building materials. at this point where we've lost 50 percent of our ocean, 50 percent of the wells and the fish that lived in the us. and when my grandfather 1st started scuba diving after the 2nd world war from disappeared. now we're

exploring that he was searched places the to still quite inaccessible. we know almost nothing of the pin on to the animal species living that the yet squared away there are results which know jill. some of the c beds they made of cobalt to nicole manganese and co pay, just the materials to meet the rapidly growing demand for batch we use as the well shifts away from fossil fuels. getting metals from our planet can be done without any environmental impact. so what we need to be thinking about is how do we make decisions that cause least harm to the planet that we're trying to protect? in june 2021, the united nations in new york was focusing attention on the highly threatening to

maureen habitats. the un proclaimed in ocean decades to advance the protection and sustainable development of the world's oceans. actress ended with a good as these challenges, so the top priorities for everyone. if you with welcome to the united decade open science together that has discovered the science we needs for the ocean, we want. thank you. mm. the, in march 2021 in the midst of the global corona virus. pandemic, special shipped was dr. the us pacific fleets, naval base in san diego, the vessel, the island pride was preparing to go to sea. its crew and the company and european scientists were going on a special mission the

as part of the mining impact program. there was such as we're heading out to examine what happens on the c bed during the world's 1st tests of us. 35 ton underwater harvesting machine called a poly metallic o manganese note, your collect to sign out. it's a big project. we want to analyze the environmental impacts of among denise and not you will collect on working in the deep sea and we have quite a few scientific groups on board. yeah. the test, this is the 1st test of it's kind of the way really close to the conditions you might expect from a deep sea mining operation. it's very important for the environmental analyses, parameters, understand it, that needs to be development, stand off the answer because that's what we're doing together with so many great

scientific groups here. a concentration of your scientific minds actually on the oil fall of some other take the we have all the technology is the marine research institute offer. we've got all sorts of equipment here, all very high tags. yes. i'm really looking forward to know that it's finally getting underway. all kinds of measuring and testing equipment we used during this expedition, including this giant boat land, which has already been in service for 25 years. the landing gear that's, that's right. but then not for the moon, but for lending on the sea fence. so very much like that we will draw, fits from the ship and most of the, with some different kinds of sensors. and then it's, it goes in free fall to 14 major steps. and then make a quiet landing on the sea. that's all we

want to know. what's the impact this of the mining, which is a concern to many people also to myself, i think we need to talk to patients of sufficient stone. they're close to where this money is going to happen. so just so you know, better that's become better predicts what the in pennsylvania such as want to investigate fast well, industry is ready to dig this advertisement for the canadian mining enterprise. the metals company promises a simple solutions. energy from the sun and wind is replacing fossil fuels to power the transmission to a sustainable future. we need batteries to store this energy. batteries are made from metals such as cobalt, nickel, copper and man. denise. until now we've been mining the earth for them, digging deeper and wider for lower quality orse. nature disappears. humans suffer.

earth suffers. but there is another way of all that's needed a mutton ray box. but is it that simple? the canadian city of toronto is with simmons this semester lives. she's the head of sustainable se for the belgian mining company g. i saw them manganese. no geo. collectivism is getting a series of tests in the pacific as we are together globally. we are facing a climate crisis and i think, you know, there is this increasing recognition around the world that we need to do something and we need to do something now. so that's a big part of that is moving towards clean energy. so moving away from, from fossil fuels and what that means is that we're moving away from

a planet fuel on fossil fuels to one that is built on metals and minerals because clean metal technology is so metal intensive. so for these were materials have come from mines on land, located primarily in asia and africa. the work is often disruptive and tom sold to nature. the mines are often located in politically unstable countries, like the democratic republic of congo, where there's not much respect for human rights. the work is often stuff written dis, working conditions risking their lives sticking metals that fetched prices fall greater than the wages. the industry says, getting results is from the c bed will be far easier. we have options about where those metals can come from and, and we're exploring one which is going to the sea floor for them. and there's a lot of reasons why going to the sea floor intuitively seems to make some sense.

and one is, we don't need to remove that for us. and in some cases, tropical rain forests are being removed to get some nickel. we don't need to remove for us or are single traits. it gets to the metal that's on the sea floor, nor do we need to move mountains to get to the orbit or body. and people don't need to be relocated. so right away those, those reasons make a lot of sense. and of course, that doesn't mean that we can just dive to the deep sea and, and not do it thoughtfully. we also have to get the research done so that we understand how to proceed well minimizing our environmental footprint to come, that'd be deep sea results collection without causing new environmental problems. the island prides deposited from san diego for a 6 week expedition to find out expect patients for hi miss you own is this mission is to investigate the environmental impact of all this

. we know a lot about this marine habitats on the if it's ecology, do you the animal? is that and if that of on this but not necessarily what the impact will be one big equipment and machines on driving around on the seat that a me of us board and have them find on our objective is simply to attempt to finalize how and to mutually take measurements, so we can present these findings to the public and a scientific key balanced way younger some chocolate is no, it's fine. science industry and policy makers all watch the expedition closely. the findings could have far reaching consequences, as humans move towards the age of green technology. the crew and researches waived fed well as the san diego sky line was seated,

the boats went off into the night of to west some countries and companies would like to develop new sources for room materials as quickly as possible to make the ocean a source of mineral results of the capable today's 10 islands located around 600 kilometers of the west african coast. the country has half a 1000000 inhabitants, most of them to send it from form african slaves. once a colony of poach ago it gained independent same noise team, 75. the even though capes. that is considered one of the most prosperous countries in africa. the stand a loss of poverty. so many the see is the source of life. with

a look at the coast line and some places indicate something is wrong here, where they were once sandy beach is a now on the stove, the on of a go x for the conservation organization. loved to now she also takes people on choice. the nature has been most of the sleep exploited here. the women. what should truck go by loaded with sand from the show. this was just bought the sand and you resell to someone else. so they come here speak to the cents and then sell it to the market. is like a small business. he's not the really big company. so there are several books and not just only one a. and as you see dozens of so much st anymore. so you need to that they're still

exist if you'd be so the is a, against the low, it's would be then a big a descent. but the surveillance is very weak. that's the big problem. it's not allowed to big sense. although there is not civilians here, but it's good to be controlled on the road. but no one doesn't of the the, the 2 conservationists con, stunned to see how these people are re, legally stripping sand from beneath the feet. no, i mean i've got another truck is loaded this time with sand taken from the sea bed days ago. the sound is sold as

rule material for the construction industry for use this back. breaking job has been the only way for people like maria to and a little money to the 80 piece ago side of it. that's very exhausting and tiring. sometimes there's even a dangerous drowning we found in the walton like this. it's dangerous so much. but if we don't do this, there is no other way for us to win money. you know, put that on the post office. would you need the conservationist think diane? ok some. are you the lodge on a lounge that years ago? the bay of leave it at the back row was a sandy beach covered with gainesville, mazda, 6 of them. nothing of that remains today. and i totally assessed the people digging

up to some to know what they doing here isn't right. i will 5. so when you walk through i've asked how much they had to do this kind of job, and that was shock because each truck is around $30.00 to $40.00 euros, and if they are desperate to sell even friends, 5 years they sell. and the job of we'll say at least around kind of thing to use a i even asked if they would like to change the job to do something else. they said, yes, it goes up. what can you see if the the

sand is being taken from the seas for use beaches and disappearing and not just in cape ready. the sand is gathered in small bouts or with a numerous industrial ships from many oceans. the impacts on devastating scientists and conservationists of low moon dive degradation of habitats for palm direct to the intellect we all consume directly or indirectly with sand or gravel that comes from the ocean's theme. this is also a very big problem in the construction industry worldwide because so much sand and gravel are being taken from beaches, including right off the coast. that entire eco systems are now changing. and biodiversity is suffering. an entire structures are being eroded um and last but not least, i organized maggio like groupings are work behind the scenes. people are forced to transport sound illegally, comfortable,

entire islands are now almost free of sand in order. it must be said to enable a construction boom in the globalized afterward west phone, which would actually have no future at all in this day and age, and it will help kind of. so this is an issue that is causing major problems in our scenes at the moment, but hardly anyone knows that probably middle high to the slice will call me month in india, africa, and all over the world, even in the north sea, sand is being dredged from sea beds, descriptions of sandy c shows no longer ring true. the, the, the suns typically makes up around one so just concrete, gigantic buildings,

and does it countries are also made of sand from the sea. because does it sound does on suitable for building the, even the sand for prestige projects such as the artificial islands of 2 by, comes from the sea for exploitation has the fatal consequences for coastal areas, microorganisms, and habitats all over the world. the meanwhile, the island pride has headed for an area of ocean known as the korean clipton zone between mexico until like the enormous quantities of pauline metallic nodules, an estimated 13000000000 towns lie on the sea. flo will it take so much

6 days for the islands prides to reach its destination. these devices held the keys to the expedition success. everything had to work. the tension was palpable. there was such as play music to help themselves relax. that is, i'm the one that's at t v 9. now this is what's called a d z nanda. and inside is a module like this, optical measuring device. so, so many electrodes all connected to it in a corner. they all these roads that we see here is a very small to the optically metro is the oxygen content in the center minutes or so the whole thing is low into the c panel. and then there was a motor on it that's program is before hand on the floor and we then use it to drive these roads into the settlement, talking and measure how much oxygen is the last of that really high attack, right? because it's definitely yeah, it's

a challenge for any device conditions. they're extreme. columbus has below the surface. the say that's not supposed to be a maximum. yes, it's just turned down that what we want to measure from the oxygen levels on the sea floor in the distribution by the produce different results when you bring them up all day in columbus in. and oxygen is something, as we know ourselves, that's essentially system how many organisms use oxygen. and we see that as an indicator of how much the system is was the toughest thing is that if you just the substrate a loss or remove it completely, you're taking away a layer that's being deposited of and many thousands of years we're active processes take place in a bind to stood it up, put, gotten rid of it, and civil and the last thing you saw. so you already have a chance to see now from the measurements. does that have an effect or does it look exactly the same as it did before? he died and although the island deprived,

has made its way to the belgian license area. this is where it was due to join the ship belonging to the belgian mining company g. i saw the boat was the test baton. yeah. the well 1st machine prototypes are collecting manganese no deals, guns, and mayor. my god lends itself the cause of the items. however, a lot of manganese nodules here you can see on the map with a mark license serious at the international c, but authority for manganese naturals are the ones at the moment. these are all exploration licensed areas for companies or countries of acquired licenses, and are looking to see how many manganese nodules are located there, which parts of the area of homes mines in on your phone. it's now we're going to the belgian licensed area and the for business license as hell for the company, tsr and then ask. and then in 2 weeks courts will go to the german licensed area which is a bit. so twist that there's the stuff one for a new guest house person of contact ha flush, a name was also on board. he was responsible for communication between the

industrial vessel and the scientist says, the tests began in the belgian license area was as, as its own, a bit like the wild west areas of mount townhome, the sea bed, the 2nd nation. so companies are allowed to explore, such as the belgian company g. i saw here. they were already in the working area. this meeting was taking place on the high seas on the loading platform at the moment and the g stood petunia, able to dive to a depth of several 1000 meters. the

its 1st knife was being per pads. the technical challenge was for me to both the device not to manage the extreme prussia and to maneuver the program to rates independently connected to the ship by a supply line. only a stick has a human um, the gsr had been developing the put tanya as in many, is this. mona model was built a few years ago now atanya to was to face its 1st real test. if it passed with flying colors, the vessel could possibly become a message for commercial c bed mining in the future.

so for tanya, too is a state flor nodule called service and i think the easiest way to picture it is to think of a vacuum cleaner. so the vehicle's been designed to pick up nodules and leave as much sediment behind as possible and then bring them to basically collect them. and eventually that vehicle be collected to a riser which will bring the nodules to the surface. but baton, you too, was designed to collect the nodules and initially collected them and have been at the back of the vehicle. and then those modules were the positives away from the, the vehicles tracks and other points in the trial. atanya was now it's several times into the deep sea to test this new technology. it looks like something out of a science fiction movie. the

meanwhile, on the islands pride full small state in touch with his ds on colleagues on the industrial ship. and was brief to how to use the manganese known to collect to for the upcoming dive. so as sylvia is quite to the show, he had to pass this information onto the scientists said that the sensitive underwater and measuring instruments would not collide with baton. yeah, now is put tanya manganese, no jewel mining in the deep sea is technically feasible. the question still remains,

how great. so the environmental risks and all they was taking the, the back in tape the day on the largest island distant jago, the some of the former sandy beaches. and now, just byron stones, owners, the sound has been gathered up and sold stones mixed with gun homepage, dominate the base. this, it didn't, it marine scene has been severely damaged. the, the world's 3rd largest population of look ahead see test whole lives around cape sadie. today the animal is on the read list of endangered species. it's strictly protected, but the removal of the sand to stubs habitats vital. so that reproduction on the

vega into a conservation organization, a committed to protecting the titles on a it's shocking to see a females struggling over the hot stones and finding no place to lay her rags. yes, if used to be a sandy beach, but i didn't knew this place before. i saw some older people and locals would describe just the place of the sandy beach tassels return to the beach where they hatched to lay their eggs. usually it takes 20 years for the animals to reach sexual maturity. that much has changed into decades. yeah, the vatican said story because this is that, that's why it's a mess here, but there is no sense. so it came out, but unfortunately it has to be fun to see. it came this morning of august, the 7th day am the

the really says because a name on the deck has wound around here. maybe i've been going to use uh uh bye to mess and when it came out the that these house being completed by human being. so this is really said, so i think we have a you to, you try to restore this place to remote the, the conservation on a has a degree in marine biology. she spent time abroad and realized that something must urgently be done in her home country to protect the ocean's nature. she found it the nature conservation organization loved to know right here in 2013. but now

dozens of help us of working on projects on the beaches. things of really taking off are usually ones because the visions to be successful. we need people, locals. so we get that. so that, that like a special for the nature of the spaces and excites no such as it was more difficult, but now he sees it as, as science. and he just doesn't. she stopped to have the top community, the space, and also uh, which drives me via life. and then to and his approach is simple, financed by donations and tries to generate awareness by adding a bit of kind of for example, photo mosquito is the name of this fishing village on the by a doe in found no health bay. the fishing boats have beached on stones the signed loan ship to way and then walks through the

village and she's proud. a lot has changed here in the last few months. the place has a new look what i can see in the south and doing the same thing. it was, it went away and as i can see, this is regarding the fishing and the books and the locals. they like it and we saw it as a positive way of make people more aware about the nature of conservation. so we saw the green, the faces about the local bi adversity, and we didn't stop yet. so we plan to do more. for instance, the global, the village in beautiful banking with rock, smoke people and so the local can associate this visit with uh, it was the reason i live in now. ocean flora and fauna decorate the facades of the houses. they are a constant reminder of the importance of preservation. the exact

to this famous marine explorer plays an important role is that the school visited by using fam in 1948 with 2 are the clinics. so don't know and the only speaker, so they came here best and equipment. they want the if you want to do some record to nevada. uh, the notion. so we decided to bring back to this family that was almost lost because the majority of the locals, we didn't even know who was jack. so and if, if she or she was around here, the check still was a legendary ocean. explore the french diving pioneer and still commentary. filmmaker introduced people to the underwater well like no other.

the hebrews images of the depths never seen before into the world's living means the crystal wanted to explode the unknown world under the sea, and called to the oceans to be protected. the . this is the french it and then took coast not far from the mouth and why rissa. the granddaughter of jack crystal and her family live nearby. after her father's death, alexandra cristo spent almost her entire childhood with her grandfather that left

smoke. she's very concerned about the state of the ocean's. i think if we continue with business as usual, where we're over fishing, we're booting, we are advancing with ideas like deep sea mining. we're going to see our ocean disappear, will continue to see a decline, and at a certain point you reach tipping points where you have exponential loss. and that's hard to come back from. you can't really come back from exponential loss, like we can put close it back in a bottle. you know that the damage is done. so once we reach those tipping points with the ocean, the damage will be done and we won't be able to reverse it. the next sondra says that her grandfather, to try to dive before she could look hon. lots of the ocean's is his legacy.

like him, she makes document trees, advocates for the preservation of marine environments, and look for ways to save the oceans the. she wishes she still has her grandfather at test site in addition to her husband, whose then now my grand father passed away 20 years ago and left a huge void in the world. not just for me and my family, but i think it felt like there was this huge cruise, so shaped hole in the universe after he died that no one himself. but what i realize is that every time someone tells me i grew up watching your grandfather, he really inspired me. i love the ocean now, and i want to do something to help protect it. we're finally at

a point in time where we can maybe 10 years ago, 20 years ago, we weren't, we didn't have the technologies, we didn't have the solution. we didn't have the urgency that we have today. and so my hope is that for everyone who loved him and loved his feelings and loved exploring the oceans with him, and that discovery and sense of on wonder that he brought my hope is that they will harness that and use that to create change. because that is the best legacy he could possibly have left us the on the cape that a islands on our entire group has help us to build the protection area for tattle clutches on one of the remaining sandy beaches. the educational signs show passes by the

importance of the oceans and the knife in them. the. this is where the tassels lay directs for weeks and then to know what she's over the catches of eggs that have been collected. here the organization ensures the baby test tools can hatch safely. we are checking which in this semester the, by now we have a 147 mess here. so the team was checking the box to the conservation for the people to have a job. so that someone in their family and also try

to have it in this fashion, the nature, the small steps, but they make a difference. the jack coastal would likely be happy to see these efforts to conserve marine wildlife the the, [000:00:00;00]

the endless expenses of bad move to stretch beyond the island, pride's helicopter platform. he is to to level the ships in the belgian license area in the clarion carpeting zone in the pacific ocean from the jack summers to your opinion. scientists watched as the belgian company g, a saw pine, the tickets, deep diving, high tech machine, from it ship the norman to energy the. now the research has many measuring instruments and senses and robots known as our fees were coming into play. no, at 4 and a half, columbus has down into the depths. they were positioned around the deployment area on the sea bed, wip atanya was making its way the

. the scientists wanted to know the impact that time you would have on nature. the control room is located on one of the lower decks of the island prides and the pilots was sitting staring at them on his, his hours as they controlled the robots on the deep sea floor. with there was an overwhelming feeling of being in a different love. the assistant station is as cost. it actually is a corner of the wells, the tweet bending now and everything was seeing him. nobody else was seen before. 7, actually, that's always exciting. scientific history was being made at that moment. 4 and

a half 1000 meters below the ship. extremely important research was taking place under extreme conditions the a special edition of conflict phone with 10 sebastian. this is a border crossing point from moldova into ukraine. premier is twice the current moment between ukraine and russia is roughly
