will you make for mines? i discover stories that can change your mind. just to click away. find out best documentary is on you to see the world before i'm ready to subscribe. now, to d. w documentary ah, with humanity mocked a mild storm recently. when the global population get it to 1000000000, or the presence of ever more people on earth is a stream on nature. as communities compete with wild life for food, water,

and space. but maybe consider the advantages of preserving animal habitats and the dangers we face. if we don't. hello and welcome to eco, india. i'm some of that. every day, there are fewer places left for why 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 that's put wetland conservation front and center with the local farming community is seeing population numbers take off. ah it's 6 am on monday morning. and farmers in a seated in ali and ged are looking for nesting, cyrus 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 hans 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 teller, said sightings, used to be read even here in that reddish, 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.

sometimes our lie explained to other farmers that this is our state, but they don't cause us any harm. they don't eat much just a little to feed themselves or not, but it is no major lost to us. hit the right, let them live in the wetlands and code of conduct. the youngest of the red headed side of the screen, which is all, was $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 this at outings. the birds build bigness that can be 2 meters light. it's one reason why they're unpopular with farmers who worry their craft will be destroyed. the contract helps explain why the thought a screen is categorized as vulnerable 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 a screens in india to date some of the biggest threats methodical. 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 manipulation, for example, when right, and we was replaced by the cash crop. so you've been, we see that the number of claims that exist in the, in that entire state in the area that has had, it has reduced quite a lot. the green specified habitat is that land depredations 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 3rd of natural wetlands over the last decade. and if the lines disappear,

the green will do. i shall hussein from the vine life of india points out another problem, garbage problem. big sickle cell. the problem is that this very 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 currently several years ago. the vi life just of india launched a special conservation project to protect the greens habitat. those, one of the names of the project is to register unprotected wetlands as far as the red line funds, evasion, 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 thought

a smith or friends of the scientists, including teddy adequacy to denali. the local community has also invested in protecting the board and it's dad. as part of a state wide project, i'm going to culture galia was invited screens and indicate that also because if there are screens, it means there's water over at lance. and if there is water, then it's so it's an indicator of agriculture. so we can with the local community to join us. and they did a lot of since 2013, more than 20000 pharma, one and 2 years across 10 districts of these have joined the project. they made up regularly to monitor water quality in the wetlands from i think it's sondra. what is the check? the period m preacher, oxygen levels are chlorine ammonia, fluoride, phosphorus, and hardness is asking a little while leaky water tissue shifted. whether sani joined the wetlands

projects 8 years ago and has witnessed a change, not just in human behavior, but also in the cranes that isn't with them at other one. so the sarah screens aren't threatened here any more. they are still at risk from cheaters and jackals, but not from human birth. within since the 1st census in 2013, when 600 side of screens were accounted in easton, author produce a reason where conservation efforts are still a relatively new development. the population has more than quadrupled the soda screen has also adapted. so the evidence seems to suggest that the grains have learned to figured out that there to retrieve does not have enough support for 2 birds to feed the chicks. and so they need a 3rd part of the helper it's adaptive behavior or death to the resilience of the

bird and tanks to therefore to from growing number of dedicated, wollen dears, 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 gems. 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, their pass, our in southern germany requires a 20 ton excavator, with a 150 horsepower. that sensing a stream runs 3 meadows before eventually feeding into the danube. one of the longest rivers in germany. biologist, marco done. it has been working in the region for several years,

many of the various waterways a 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 you while the water flows at a uniform speed on. and the bed consist of only sand and small pebbles were there aren't any larger stones or boulders on the gornstein in the face working for you. basically, there aren't any naturally occurring structures in the stream lead, provide variety and help stabilize. the bed is longer logging into this. 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. canada almost on this sort of situation is not good for wildlife fringes because

a lack of structural diversity in nature. it leaves wild life with less scope to find a suitable habitat too. 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 latrevia, you get some ideal habitat. it's when the material that's being re introduced gets mixed with the final pebbles and big rocks if like this one that protect against stronger currently wash dark restroom. all would of good crap contracting now and then nature itself gives the restoration efforts an unexpected boost. here's a melissa 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, there's 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 that also inhabit the waters. a perfect food chain. germany streams were one's home to thriving, fresh water poll muscle populations, unless it is here soon. 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 need young. it's a housing if working on captive breeding programs a currently the best way of boosting fresh water pal 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 living 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 then flows into the container with the host fish as well. the brook trout best flow from the river put in there from it, then gets their food in buffalo. hundreds of brook trout live in the tanks and they need the muscles to successfully complete their reproduction cycling these subtly 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 wicked. these have developed,

well that's in there, we'll be releasing them quite soon. the next on the most important is the shell links on there. 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 gravel. and can then cope well with the conditions in the water and live in the vessel gone switzerland. but before that can happen, more streams need to be restored and then muscle baths 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. i'm the water noise ever since the industrial revolution, human activity in and around marine embodiment has will bod of the seas with salt. as we discovered the effect on creatures, large and small, is disorienting and destructive. 2 2

ah, 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. and the way things are going, the underwater world is set to become one thing. even louder with devastating effects on marine life. oh kidding tis predator lloyd incense in their environment . so ruin findings had actually 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 is 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 fog. 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 when energy is generally a good thing. but installing offshore turbines creates a great deal of noise. in the north sea damage the hearing of porpoises driving them away from their feeding and breeding grounds. the entrance are most

lightly exceed pilots and they have to drive into the steep it by hammering or in pick pile driving. and this course underwater noise which is smallest, comparable as in 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 floor conditions, wind waves,

weather conditions current and so on. but thanks to ty, to 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 work 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 boils and creates the am 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 the 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 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 alls, old plankton larva, within a kilometer of the explosion dropped dead. they insure the health of the ecosystem here, one's on credibly 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 a good faith rapier arm off. whereas a virus eyes on land, you can put an egg underneath and panic 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 this green 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 reasons 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 helpful sort of values about the need to protect species. we met a new application officer in chennai was committed to doing just that. i me see that the green iguana sealer 30 threshing splash of cool water. a new born gavia called its mother and broke her heart global so that she can the madame crocodile bank sees the bees allows web users to get up close and personal with all these animals that are due in the southern indian state of not being them online. will encourage

visitors to drop by in person and learn more or less tell you when people come to the create, you gave them about the animals, how these animals live and eat. we give this information to the people that does 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 his ease. under protection. and my task record l bank was designed to help provide numbers with a breeding program at the beginning, the house, exclusively crocodiles nowadays its own too many other reptiles like turtles equinox and make it nick that people are particularly scared off. they are deemed to be dangerous. stuffy. john works closely with all the animals. tried to call 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 fees on educational well, she wants people to understand them. no, no more in india and the 50260000 people die because of sneak bite. hans, it is very important to spread awareness about snakes, but they didn't get that. stephanie jones received a b, a in lodging in time. and afterwards she did a masters in biology and conservation. in portland, she was recently elected to prevent outpatient in the international educators association role, which put her in dialogue with lose worldwide, who had who educated my main ambition and goal is to create a change in people's perspectives about animals. this exist 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 the importance of animals, of 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. the pandemic blog down presented the zoo and its employees with many telling 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, they keep those social media, but then helps it to find the table sponsors and ensure the protection of india injured. reptiles is you into the future planet. tribes on balance. as we've seen, to the, the ult 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 us in india and germany. good bye, and thanks for watching with

imagine how many pushed out in the world right now to climate change. if any, off the story, this is much less the way from just one week. how much less and really get we still have time to go. i'm going off
