a reporter tracks down the arctics. major players with you see route begins a dangerous game. people overseas that yeah, we are here. we're patrolling the area now, the cards are being re, shuffles, has the best tattered russia is quite economic in the arctic. if you see something that looked like james bond, it has to do with the military. it starts december 23rd on d. w with humanity mocked a mild, stormed recently, when the global population hit 8000000000,

or the presence of ever more people on earth is a stream on nature. as communities compete with wildlife for food, water, and space. but maybe consider the advantages of preserving animal habitats and the dangers be faced if we don't. hello and welcome to eco, india. i'm son of that, a group. every day that a few will places left for y life to call home even in places where they are emblematic of a whole region. big the northern indian state of the british for years, it's official bird. the sawdust screen has been under intense pressure. now an extensive outreach program. let's put wetland conservation front and center with the local farming community is seeing population numbers take off. ah, it's 6 am on a monday morning and farmers in

a cedar than ali and ged are looking for nesting, sawdust, greens. they are part of a conservation organization and have been working to protect the clean population for over 10 years. cited screens are the only resident reading koreans in india and the world's tallest flying bird. knocked him yarn, sir darcy, licky. i get a torch in the night to check on the nest and eggs i protect them and make sure nobody harms these birds or tries to kill them. i take care of the tags and nest, so the birds are safe. i liked their presence here. walter taylor sat sightings used to be dead even here in that radish which is home to nearly 70 percent of india solder screens. and in a decade ago, if farmer saw the birds on their farm land, they would shoot them away. take their eggs or even kill them.

i've got some thou and the lie explained to other farmers that this is our steered birds. they don't cause us any harm. they don't eat much just a little to feed themselves, but there's no major lost to us out of the way. let them live in the redlands and coexist. elliton calibri 11 ransom the red headed side of the screen, which is all of $150.00 centimeters stall, on average. usually nests in natural inland wetlands or in fatty fields where the tall ice crop ensure that its eggs remain protected. using straws and grass from the surroundings, the birds build bigness. that can be 2 meters live. it's one reason why they're unbar below, with farmers who worry their craft will be destroyed. the contract helps explain why the solder screen is categorized as one of the bulls on the international union

for conservation of nature's list of species. according to the w, w, f. they are now only 15 to 20000 side of screens in india to date. some of the biggest threats and therefore not surprisingly are because of the way in which human beings are using the landscape and how to change the use of the landscape. so in my new products, for example, when right, and we was replaced by the cash crop. so you've been, we see that the number of cranes that exist in the, in that entire state in the area that had it, has it used quite a lot the queen's bedford habitat is that land for the she is home to some, 2200 square meters of wetlands and area twice the size of hong kong. but now some of these valuable ecosystems are being destroyed to make way for so i feel according to the non profit red lines, international, india has lost one, towed off its natural wetlands over the last decade. and if lines disappear,

the greens will do i shall hussein from the vine life of india points out another problem. garbage problem ya, big sickle cell. the problem is that this land was in its natural estate a few years ago. but in the meantime, it has been leave. the laser has converted the land into smaller bonds, as you see because he lives on a scope on scope neutral ship, which is probably several years ago. the vi life just of india launched a special conservation project to protect the greens habitat. those one of the aims of the project is to register unprotected wetlands as the wetlands funds, elation and management rules in order to protect them from exploitation. so far the project has a disturb 37 of the 51 identified wetlands in the region. meanwhile,

a group of more than 151 and years act as situs mithras or friends of the scientists, including the anaesthesia denali. the local community has also invested in protecting the board and its dad. as part of a state wide project, i'm going to call joe galia was invited screens and indicate that all think because, i mean if there are status screens, it means there's water, overt lance. and if there is water, then it said it j b. so it's an indicator of agriculture, so weak and with the local community to join us. and they did a lot of since 2013, more than 20000 pharma, one and tears across 10 districts of the for these have joined the project. they made up regularly to monitor water quality in the wetlands from i think it's on the check that be a temperature level high chlorine ammonia fluoride. what sort of an hard now

is that a little fun to watch whether sonnet joined the wetlands projects 80 years ago and has witnessed a change not just in human behavior, but also in the greens. i'd rather the service k, it's aren't threaten here anymore. they're still at risk from cheaters and jackals, but not from the birth of the thing. since the 1st census in 2013, when 600 santa screens were accounted in eastern author for these a region where conservation efforts are still relatively new development, the population has more than quadrupled. the saddest grain has also adapted. so the evidence seems to suggest that be great, have learned to figured out that there that it really does not have enough food, but 2 birds to feed the chicks. and so they need a 3rd. but the headboard,

it's adaptive behavior or death to the resilience of the bird and tanks to therefore to from growing number of dedicated one and deers, but halves, it won't be long before the cause of the thought. a screen will be heard more often . the fresh water pearl muscle is a globally endangered species prized for their delicate gyms populations, have been decimated by hunters, agriculture, and water pollution conservationists in germany are working to boost their numbers . and as this next report from southern bavaria shows that can involve some pretty heavy machinery. restoring this stream net pass, our in southern germany, requires a 20 ton excavator with a 150 horsepower. but sensing a stream runs through meadows before eventually feeding into the danube. one of the longest rivers in germany. biologist, marco janet,

has been working in the region for several years. many of the various waterways are badly degraded when i was a young man and give us obstinate via this stretch of water has no structural variation. the i'm tunic, one of you can see that it's deborah doesn't vary while the water flows at a uniform speed on. and the bed consists of only sand and small pebbles. were there aren't any larger stones or boulders on the golden shiny face. fortunately for you, basically the round and he naturally occurring structures in the stream lead, provide variety and help stabilize the bed is longer valid and into this. so for decades, streams like this one were adjusted to suit agricultural needs. for example, by making sure the water flowed faster to make it easier to drain meadows and farm land in wet weather. kennedy,

i understand this sort of situation is not good for wildlife fringes because a lack of structural diversity in nature, leaves wildlife with less scope to find a suitable habitat to and so frankly, the excavator is helping to re introduce that structural diversity, distributing boulders, stones, and tree roots and leveling the banks. philly, i live lead zavion, you get some ideal habitants when the material that's being re introduced gets mixed with the fine of pebbles and big rocks if like this one that protect against it. stronger currently wash, darker, remove wood of good type contracts and now and then nature itself gives the restoration efforts an unexpected boost. he is a mom. listen, beaver dam. we are obviously not the only ones trying to reshape the stream. michael aquatic plants, insects, fish, crayfish, they will return to the stream which was restored several years ago. but according

to marco, done it the still no sign of any fresh water po muscles. it's an endangered species and nearly extinct due to harvesting and pollution. the muscles play a key role in the ecosystem because they help purify the water. they filter out tiny organic particles from the water. they taken this benefits of a species big and small, but also inhabit the waters. a perfect food chain. germany streams were one's home to thriving, fresh water pole muscle populations unless it is saturn, you can see the difference in size between a muscle that's at least 50 years old. and a young one that's about 8 years old from a breeding project. in recent years, they've both made their home here in the area said i didn't young yet. so i was like a 4th non captive breeding programs are currently the best way of boosting fresh water pell muscle populations. since most river habitats

a to degraded conditions in the breeding stations are ideal, and the muscle can flourish, the thick is then live through. the trick in the breeding program is to replicate the life cycle of the river pearl muscle, which is a bit complicated. it's got lockers, we keep mature muscles and wait for them to release their larvae into the water. the water in the crate them flows into the container with the host fish as well. the brook trout lived there. life on the river foot in bed from with the nets were full in buffalo. hundreds of brook trout live in the tanks and they need the mussels to successfully complete their reproduction. cycling these, settling mcgill's for about 9 months before falling off. they're not yet ready to be released into the wild. they spent the next few years in boxes with water flowing through them in a stream next to the breeding station. and a regularly monitored he hung vis. yeah. good and tickled these have developed.

well they're sending, we'll be releasing them quite soon. the next on the most important is their shell length. i should be about one and a half to 2 centimeters long, because then they've survived the critical juvenile stage, which i spend in the crevices in the gravels has been bubbling and can then cope well with the conditions in the water. and the thing when you get a social consequence, but before that can happen, more streams need to be restored, and then muscle bads can play their part in repairing the ecosystem. staying under water and to an invisible problem that severely impacts why life in all of our oceans under water noise. ever since the industrial revolution, human activity in and around marine involvement has will model the seas with salt. as we discovered, the effect on creatures,

large and small is disorienting and destructive. 2 2 2 2 ah lou, the ocean is a symphony of sounds, at least where they can still be heard. we humans have made the sea noisier than ever before. lou and the way things are going, the underwater world is set to become one thing. even louder with devastating effects on marine life. so keeping to predator avoidance sense in their environment . so really finding are deducting the whole day. let's explore some smart ways of turning down the volume in the ocean and find out why this might also be good for the climate o. underwater sound. waves traveled extremely fast and up to thousands of kilometers.

sound is essential for almost all marine animals from whales to jelly, fish, animals you sound to communicate, to navigate and define mating partners or pray. but hearing what those creatures need to hear it's getting increasingly difficult. summary life is currently exposed to noise levels that can destroy their sense of hearing, literally render them deaf or kill them. it's like you're logging around in a thought that's a pretty serious effect to for animals that depend on sound so much. so why are the oceans becoming so noisy? one factor is offshore, wind, farms and wind energy is generally a good thing. but installing offshore turbines creates a great deal of noise in the north sea. it damage the hearing of porpoises

driving them away from their feeding and breeding grounds. and perform agents are most likely exceed pilots and they have to drive into the steep it by hammering or mpeg pile driving. and this course underwater noise which is smallest comparable. s and stopping aircraft. the sounds emitted by the pile structural elements smashing into the sea floor travel several kilometers from the source. but help is on the way compressed air flowing through tubes on the ocean floor round the piles creates bubbles that rise to the surface, forming a tight insulation curtain. fewer sound waves managed to penetrate the barrier leading to a 90 percent reduction in volume. this is how things sound without an air bubble curtain and this is with an air bubble curtain.

challenging issues that if to, to lift with feel for conditions, wind, waves, weather conditions, currents and so on. but thanks to tighter regulations, the curtains are now almost standard for construction off germany's north sea coast . and interest is also picking up in the us, the netherlands, and taiwan implementing bubble curtains cost just one percent or less of the total investment for an offshore wind farm. music loud, we're going in. so wind turbines are one thing, but there's a bigger problem. container ships international shipping is by far the main source of noise pollution in our oceans. the culprit and the potential solution is the ship's propeller. domestic pressure cooker is worked by controlling the steam pressure inside them, pushing up the temperature at which water boils. the resulting higher heat means

faster cooking. i ships propeller the opposite happens, not with food, but with water and effect called cavitation. so it, due to the fast motion of that propeller through the water. locally, the pressure is extremely low so that ambient temperature, the water boys and creates them bubbles, creates a vapor bubbles. and these bubbles grow. and these bubbles shrink and collapse. this generates noise levels comparable to a rock concert on dry land. the solution has the potential to be good news for the climate. and the profit margins of big shipping companies, essentially, fewer bubbles can mean lower fuel consumption. in 2017 denmark based mask retrofitted, the propellers and engines of 5 vessels, primarily to say fuel. but their sound emissions also dropped by 75 percent.

this add on device improves of vessels flow in the water, which according to its maker means less cavitation and fuel savings of up to 8 percent. but installation isn't cheap. and shipping, firms are rarely obliged to make. the changes with cargo price is currently very high. they prefer to keep ships in operation rather than investing in a retrofit for many ships. that could be savings possible, especially due to the fact that each ship needs to go to dr. dropping each say, each a 4 to 5 years to incentivize ship operators. the port of vancouver has cut port charges for certified quieter vessels by as much as half but the loudest defenders are seismic air guns. the fossil fuel industry uses them to locate new oil and gas fields in the ocean. their sound waves are as loud as a spacecraft and can be heard hundreds of kilometers from the source.

for days, sometimes even weeks or months, these tubes fire out compressed air every 10 seconds. with every blast, 2 thirds of all soul plankton larva, within a kilometer of the explosion, dropped dead. they insure the health of the ecosystem. air one's incredibly wasteful. they're way too loud for what they need to do. i rightly the fossil fuel industry is itself conducting research on more environmentally friendly methods for its surveys. one technique is called marine viber size, which generates the required signals via vibration instead of an explosion. the result is more of a constant hom, rather than a big sudden blast and air gun, so strong it could be, could rip your arm off, whereas a virus eyes on land, you can put an egg underneath and, and long great initial models suggested the impact on marine life would be just 10

percent of that of an air gone. the likes of exxon mobil total energies and shell may have their eye on another advantage. however, marine viper size can also map oil and gas in shallow waters. but doesn't this sound paradoxical, more sustainable methods to find more fossil fuels? we really should not be, we just should not be searching for oil and gas under the ocean anymore. we, you know, we really need to make the screen transition. that's the main solution. there are plenty of options for reducing marine noise pollution, but more progress is needed on the regulatory front. in 2011 germany introduced one of the world's 1st noise limits in place to protect north sea marine life. air bubble curtains are now standard, there in the industry is doing fine. taiwan is introducing a similar regulation. quieter is better for the environment, but without incentives or new laws,

the industry has few reason to change. the role of those in conservation is controversial, but some argue they play a valuable role in educating the public about animals and help foster values about the need to protect species. we met a new education officer in chennai was committed to doing just that. i me see that the green iguana see were 30 flashing splash of cool water. a new born gavia called its mother and broke her heart global a bunch again. the madame crocodile bank sees the bees allows web users to get a blues and personnel with all the animals that are in the southern indian. they

adults not being them on line income visitors to drop by in person and learn more about them unless you, when people come to the create, you gave them about the animals on how these animals live and eat. and we give this information to the people of those who was founded in 1976 a time when crocodiles had almost gone extent in india due to the trade in crocket . i leather, the government, please burton's disease under protection. and my das crocodile bank was designed to help provide numbers with a breeding program at the beginning, the new house, exclusively crawford, as nowadays, it's home to many other that i don't like turtles ego on us and make it snakes that people are particularly scared off. they are deemed to be dangerous. if he's on work closely with all the animals them, unless you don't mind,

it's not like they do not bite. if they bite, we have to endure it. animals cannot talk and biting is how they express themselves . i think that was a big role in on educational well, she wants people to understand them. no, no more in india, every year. 50260000 people die because of sneak bite. hans, it is very important to spread awareness about snakes, but they didn't get stephanie. john received a b, a in the lodging in thermal. afterwards, she did a master's in biology and conservation in portland. she was recently elected to prevent keisha in the international educators association, a role which put her in dialogue with those worldwide who ada, who educated my mean ambition and goal is to create a change in people's perspectives about animals. this exists because of that,

so that people will get curious about animals and get to learn more about them, that they will also learn about how to build a better future, where people and animals can co exist harmoniously. they can also learn about vein borton's of animals. humans and animals are dependent on each other, setting the goal of a way to make people understand how we can both going with that depend on make blog down for then it does all and it's employs with many jalen you with visitors, forced to stay home the lag income, but that obstacle helped it in a way. now companies and individuals can adopt animals and help finance their keep those social media and then helps it to find the table sponsors and ensure the protection of india injured you into the future.

our planet drives on balance. as we've seen, to the, the ot belongs to every living organism, not just human beings. the movie embodied this, the movie ensure the security of photo and species. think about that and i'll see you again next week from all of was in india and germany. good bye. and thanks for watching with
