a houses that daniel leaders can't construct far more than just buildings. he is the son of jewish holocaust survivors. how, what do you that i was able to bill to just present berlin is architecture, is a celebration of democracy and peace and architect of emotions. daniel starts december 25th on d. w. humanity mocked a mild, stormed recently when the global population hit 8000000000 on the presence of a lot 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, there are fewer places left for why life to call home, even in places where they are emblematic of a whole region. think 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 seen. population numbers take off. ah it's 6 am on a monday morning. and farmers in a seated in ali and ged are looking for nesting, sawdust, greens. they're 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 nurse 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 teller, said 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 farmers 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, but it's no major loss to us. hit the right, let them live in the wetlands and course they have color on the red headed side of the screen, which is all was 150 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 their surroundings. the birds build bigness. that can be 2 meters live. it's one reason why they're unpopular with farmers who worry their craft will be destroyed. the contract helps explain why the sod screen is categorized as one of the bulls on the international union for conservation of nature. lift off certain 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 british for example, when right then we were replaced by the cash crop. so you mean, we see that the number of claims that exist in the, in the entire state in the area that has been, had it, has it used quite a lot the cranes 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 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. ya. 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 natural 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 aim for the project is to register unprotected wetlands as far as the wetlands conservation and management rules in order to protect them from exploitation. so far the project has just stood. $37.00 of the $51.00 identified wetlands in the region. meanwhile, a group of more than 151 and years act as far as the mythos or friends of the

scientists, including cheddie, advocacy 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 side of screens, it means there's water over at lance. and if there is water, then it's 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 2 years across 10 districts of the for these have joined the project. they meet up regularly to monitor water quality in the wetlands from i think it's larry for august. the check, the period them preacher oxygen levels are chlorine ammonia, fluoride, phosphorus, and hardness is okay. a little quality 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. other other ones are the sarah screens aren't tritton here any more. they're still at risk from cheaters and jackals, but not from you. lambert, forth with him. since the 1st census in 2013, when 600 side of screens were counted in easton, author produce a region 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 barracka retrieves does not have enough food for 2 birds to feed the chicks. and so the needed 3rd blood of the headboard. it's

adaptive behavior or death to the resilience of the bird and tanks to therefore to from growing number of dedicated volunteers. but halves, it won't be long before the cause of the thought a screen will be heard more often. the fresh water boil muscle is a globally endangered species. priced 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. but 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. and 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 very rise. the water flows at a uniform speed. aunt and the bed consists of only sand and small pebbles. were there aren't any larger stones or boulders on the gornstein in the face. fortunately for you, basically, there aren't any naturally occurring structures in the stream that provide variety and help stabilize. the bed is longer logging 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. it leaves wild life 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, flew the olive. let's vivian you get some ideal habitat. it's 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 stronger currently wash dock, restroom order, good type contracts and now and then nature itself gives the restoration efforts an unexpected boost. here's a man to mrs. beaver dam. we are obviously not the only ones trying to reshape the stream. will aquatic plants, insects, fish, crayfish, they will return to the stream which was restored several years ago. but according to marco done it there still no sign of any fresh water pole 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 once home to thriving, fresh water poll muscle populations elicit, here's the afternoon. you can see the difference in size between the 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, most made their home here in the area that i need young. if the housing captive reading programs are currently the best way of boosting fresh water power muscle population. since most river habitats a 2 degraded conditions in the breeding stations are ideal and the muscle can

flourish, the thick is thin living. the trick in the breeding program is to replicate the life cycle of the rhythm muscle, which is a bit complicated if we keep mature muscles and wait for them to release the larvae into the water. the water in the crate then flows into the container with the host . fish is the brook trout. that's like some food in there. and we can get this thing off of the hundreds of brook trout live in the tanks and they need the muscles to successfully complete their reproduction cycle. 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 hums are saddled and trickled. these have developed well

this and there will be releasing them quite soon. the next on the most important is there, showing, showing that 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 in their social consequence. but before that can happen, more streams need to be restored. and then muscle baths complete their part in repairing the ecosystem. staying under water and to an invisible problem that severely impact why life in all of our oceans, under water noise. ever since the industrial revolution, human activity in and around marine involvement has lombardo, the seas with salt. as we discovered the effect on creatures, large and small, is disorienting and destructive

lu, the ocean is a symphony of sounds. at least where they can still be heard. we humans have made the see 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 kid creditor, lloyd incense in their environment. so really finding seduction ok. 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. underwater sound. waves traveled extremely fast and up to thousands of kilometers.

sound is essential for almost all marine animals from wales to jelly, fish, animals you sound to communicate, to navigate and define mating partners or prey. 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. it damage the hearing of porpoises driving them away from their feeding and breeding grounds. then agents are most

likely exceed pilots and they have to drive into the steep it by hammering or and 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, 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 ah, 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 my ship's 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 ah, but the loudest offenders 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.

oh, for days sometimes even weeks or months, these tubes fire out compressed air every 10 seconds. ah! with every blast, 2 thirds of oz, all plankton larva within a kilometer of the explosion, dropped dead. they insure the health of the ecosystem. here one go credibly wasteful. they're way too loud for what they need to do. ironically, 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 by a 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 may take the rip, your arm off, whereas a virus eyes i lamb, you can put an egg underneath a panic raw, great initial model, suggest that the impact on marine life would be just 10 percent of that of an

aragon. 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 to 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, and 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 to vanish about the need to perfect species. we met as though education officer in chin night with committee to doing just that. ah, fever, the green iguana sailors, i refreshing splash of cool water. a new born gavia called what it's my dog and broke or dial, taught global so, but she can madame crocodile bank sees the beans, allows web users to get up close and personal with all the animals that are in the southern and in the adults. not all being them on line will income 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 of those who was founded in 1976. our time when crocodiles had almost gone extent in india due to the trade in crocodile leather, the government pleased perkins received under protection. my dad's crocodile 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 to like turtles equinox and makes it nice that people are particularly scared off. they are deemed to be dangerous to feed on what clothes, leave it all the animals got 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 of how they express themselves or not, but that was really a big role in steph. he's always educational. well, she wants people to understand them. no more in india and the 50260000 people die because of sneak bite. hans, it is very important to spread awareness about snakes. 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 keisha in the international educators association, a role which put her in dialogue with lose ward. why i her who, who educated my mean 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. humans and animals are dependent on each other, setting the goal of as always, to make people understand how we can both going. with that, the pandemic logged down further entered the zoo and its employed with many children do 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 had those social media and then helps it to find the table sponsors and ensure the protection of endangered reptiles you into the future. our planet drives on balance, as we've seen, to the,

the alt 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
