sewage of the 77 percent every weekend on dw the, on the show, we often speak of pol critical nature. it is for also vice hello and welcome. i'm sorry because the body and you're watching equally and yeah, but it is our own on sustainable human activity. that is the biggest, perfect for awesome on it. so what can we, as individuals, do to save and preserve our ecosystems on today is episode. let's meet a few individuals who are dedicated to making a difference. we begin in the south of india and the town of orleans. it is an experiment in equal village with an international community which is known for its

massive reforestation initiative that started some 4 decades ago. today. a team of specialists gas for these green loans. uh, some people that 3 doctors trying to look off to each and every one of their patients they looked like number petered out with heavy chainsaws harnesses, fuel canisters and has but rather than selling trees these men on a mission to save. here in the south indian township of a row with every 3 guns. that's why a homegrown team of experts, then students green grinning branches. when i was young, my father had a friend who was starting to build 3 houses or so as a sample. they build one in our backyard. this such a different view and experience and you get to being up there and feeling the wind

blowing on you and feeling the breath of the tree. that's something i feel to this very day. bother you out for a color scares for our woods priest together to join us. so shown that the founder of maintenance company, pre k, they both grew up here and it says to communities, 34 decisions efforts done this one's about in region 2. a lot of green landscape, the transform mission in stairs and them a lot for nature, which that down into a profession, arborists or, or our board culture is it comes from the latin word arbor, which is tree. and so we're treat professionals. we are, i think how i see it is that we provide a bridge between nature and our urban environment in the last decade. the state of some and not who will or will is located as last toes of trees to psych

loans. these are growing most frequent due to human induced climate change, a pa, for the storm in 2011 greek have and resident a got their full cause is young and she was destroyed by the point of having defend her favorite treat. it was during the psych loan and the morning or the gal done, it was a completely destroyed. and i am going to the swimming pool to check a how is it? and i saw this tree who was called the key coating in 2. and i say it was very loud to you, you see that it's growth from 2011. and this is the, it was the same. it's less cold. lucky. we'll put that on there for me. and it's for me up so we can proceed. but to imagine we have 2 goods, this tree,

the damage. luckily, the expert a tree, get a solution, right? we did our research, we try and figure out what's the best way of going about it. and we finally settled on a bracing method that is quite popular. also in europe using threaded drugs, we actually, um, drilled through the entire tree with a really long drill bit. um and inserted a threaded rod. uh, crated some metal plates to basically a force that closer again. but even with the best efforts of boat, it's gone. save the victory that typically come into the picture once. it is already affected by it, less or damage. even though trees can be surprisingly adaptive in oven, and ones that are often susceptible to disease and root damage. the island let's go

is an auto. the base board is specialized in the management of urban trees. he advocates presenting mature trees in new building development. i am actually going and looking at the trees on the sides to look at sort of how long these trees each individual tree will be. therefore, i've taught them on a map so that it can be integrated in architects drawing. they're all 0 located. we're looking at their, their health looking at their condition, the structural condition. we're looking at how rare they are, how old they are, how long they are going to be there for how much longer they're going to be there for. and based on all of these factors, you can essentially grade them. this approach helps boost ebony green reads the villians through this process of changing climates such as drought, as well as to pollution and lots of biodiversity in the open nickel system. auto woods, cree doctors are always on the lookout for early warning signs of a stretch. here's another clear sign that this tree is dying back. these,

all these shoots are actually from the same tree. it's coming from the, from the roots. and these are stress shoots as the top of the tree, the canopy is dead. it needs to find a new source of energy. and so it's shooting out all these new epic one. make sure it's in a last ditch attempt to create a new kind of p for itself. 3 good dreams. a spawning arbor is the leasing them how to adapt assigned to the technique using different parts of the board on pop, the local conditions. it's june us so shall next. so that just new crops of practitioners will help us spread a sensitive a pro se claimant device beyond the tree tops of our old yard. and in the cities, millions of dogs, monkeys, and calls roam the streets with no access to the water or shed. these 3 suffered extreme, the events that are becoming more frequent because of human induced climate change . we met a woman named tony who was who just by that light,

that she decided to take action a step that benefits many times will find dynamos. city. excess space is with the main threatening point to sort of start the organization was there was a dog who had a disease broken 9 distemper and um, you know, just watching it um, die without getting any kind of relief. you know, that suffering should not be that it was the 92007. i had a job at that time. i was working with a healthcare company and i decided to create or hide it in my mind that i want to start an organization. you know, because there's only so much you can do under one of my name is i may have been telling me i'm on the founder and president all for ask your child to be addressed. i will call you myself and i'm going to ask your

specialist. i'm a born and brought home by going and that's it. all i saw it on me were dogs and gotten but you know, sort of those are the 1st one uh that i started to, to ask you of the, in 2014, when the snow at their band was enforced. nobody talked of the aftermath of what's going to happen with that. so suddenly you'll have a whole lot of can't do that job binding and eating. gloster, getting into the accidents. so that's when we started doing more lodge on the move up in 2007. when i started it was literally nobody providing emergency services or any kind of on the move 3 or either a screen and on

a move on for you. or you bringing the animal into the rescue center because it needs additional help. so it's good for here where it's undergoes. do you have the dish and then is it didn't the introduce back to the right and or the touch situation you kind of respond to is you know, a conflict situation where you're trying to make a good mitigate or conflict that's happening. know that for example, could be um, you know, maybe a leopard made a live stop kids and people are angry, you know about it and you're trying to mitigate that the after eventually activities are focused on community awareness education. the big guy has a couple of friends trying to uh do word for it and it moves into what. what do you see today is the 1st responders you see,

do you have the data as you see of at city department? the organization is um, completely funded by donations only i think we're at a point red incidence ohio simply because of so many changes in a night and i environment the one of the visions that i have is to develop a network of remote squads. um, and this basically means to provide employment to locate papers who are passionate about friends are going to have a died conserving, why life and skimming them a quick thing. them the, it's about keeping you know why life wide. it's about sending them back to the why

we're not as you the and the best part is when you would use them back out. they don't even go on and look at the ition of expanding in many countries, including india. it is also one of the fastest growing sources of greenhouse gas emissions. it generates avenue and android. what does that mean? we stopped? well, that seems relative. but as far as who can walk on electricity, then why contact me? my call is i just need as to go back to the skies region to find that it won't surprise you do here. is that how we fly today needs to change? ition makes up for on 3 percent of global emissions. and okay, that really doesn't sound so bad, but by 2050 that numbers projected to rise to over 8 times, but, and there are no real ways to fly pollution fee. so what is, why are you,

what is the most promising solution? so a vision for you sion, a biofuels, a more broadly sustainable aviation fuels that mostly made from non petroleum products like bio mass. so again, you can basically just swap the fossil fuels and heal for biofuels. i'll make a blend, but we need so much of it. the scaling up is very hot on the line to be used for other purposes, like drawing fluids or saving far. and then there's also hydrogen that shrink on this. especially hydrogen made sustainably, a lot of prototypes are being tested. electric plans are a 3rd option, and they can make a really compelling case here why we never, we, we run off hydro power or wind power. so then to consider we have is this sustainable renewal. so for us that's, that's the demo sustainable we can do right now for the, for us, this is you on know, but as going of a, the issue and one of the only people flying airplanes every day. when an a v,

as in school, in sweden, where future pilots are being chained and flying electric lands. the paper streaming bell as they fly here, it doesn't mean much electricity. it takes around an hour and a half to charge, which has been slide 45 minutes, but the result of 30 percent patchy is mostly used for pilot training or private key. she left the airport has a one mega, what charging station, which is enough to charge a small fleet of electric plans at the same time. so i get faster to get in. so ask 1st, it's easier. i'm ready. all right, let's go the fast. this is a super light plane, but it can only go to people with no have luggage to go. any bigger

e plans are faced with a big problem. heavy batteries blowing, 747 to fly from say, london to it's done with batteries. will need to be based much heavier than a full time. this just going to work, since this wouldn't be 10 times heavier than the heaviest payload ever lifted. when you're storing energy, you need a very high level of energy density. that's good garry, head of the apples program of the u. s. department of energy use national renewable energy lab or and petroleum and petroleum related products or petroleum. dr. products like biofuels have a really high energy density when compared to the energy density of traditional fuel batteries. they have very poorly coming in at only 2 percent. but conventional aircraft, we fly and today i've been is for jeff fuels. it all started with the design off and the 1950s. they've been propeller plans the most popular at the time. and still,

by an end to it looks like this. the performance characteristics between those 2 aircraft where the turban was slightly faster, but it could go as far. and, you know, you got marginal gains by doing that. and then 5 years later, they figured out for different sizes, for different configurations, all of a sudden it makes sense to use these because of now how like you can make a circle. overtime this though bye and or cuban wing design became vastly more efficient. ok, a window of theories. today's deadline has been almost 50 percent less fuel passenger kilometer. then they did 50 years old with the help of better engines improve aerodynamics and a lot of other open, invisible changes. but the thing is, this design has peaked in the way it's very hard to become more carbon efficient unless you squeeze even more people onto already very died plans. so governments and many of the industrial going back to the drawing board to redesign this is dawn bought a vision expert we looked at on the ground infrastructure to support the transition

by working together with detroit. but we looked at 2 main modes of operation for doing that one, which was a battery charging system, so where the battery would remain fixed within the craft. you would plug it in as if you would like a normal device. you would just charge it. this would be the simplest way operationally speaking, but they also found that charging would waste precious time when current air traffic relies on a quick down around bands. what, okay, by limited space in the airport and of course the amount of power needed would take away significantly from the city's grid. the 2nd sort of mode of operation we looked at was a battery swapping system. and that would be where you would have pre charged x rays. and then when an across came in, you would remove the battery from the frame and then swap it with one that had already been pre charged. this would save space and time, but it would require a lot of specialization, which we currently don't have anywhere. and it wouldn't be a big risk. meddling with an airframe is always dangerous. and there's also the

major risk of files from holding so many batteries in one place. so of the 2 systems we, we favored the battery charging system. but we were very aware of the potential limitations that, that comprise. so not easy. yeah, i mean you can find your so what do i do if you want to know if it go down for just x board, if you want to expect those 2 positions with the 1st plans to be certified. but this is another huge shot and you've got a vision has compared to cause being certified for safety. so everything takes time for r n d testing and tony for battery safety and the use long certification process. but this january, the urban, solomon bush, for the idea of more e plans for shot in mid range flights. this is part of

a while ago to got 90 percent of emissions from transport by 2050. all right. thank you all those crazy said, i know my mother actually. okay. the company than me that the district is now working on a full see the plane and the already bigger ones. a plane called alice secretary, 9 passenger. the 2 crew members seem to be close to commercialization, promising to fly around 400 kilometers. a hot aerospace in sweden has a proof of concept aircraft that looks like 25 passengers up to 800 kilometers by 2026. when you look at, if you think about their existing cargo routes that use small aircraft, their existing communities, that they're only connection is a, as a 9 senior crap unless they take a ferry for or 6 hours type of a situation. and those are real existing route that have to be either subsidized or paid for by by communities. this is the main application so far, and it is significant. in 2020, the us spent $326000000.00 to subsidize the costs of across the smaller apples. the

don't see a profit ambulances at the axis. and small cargo plans also need only small across the 2 and has ordered 12 plants for low emissions postal deliveries, which can help local noise in a quality to a study by the international central and team evaluation estimates. the electric aircraft good govern 9 percent of the coming to markets. that slides with more than 19 passengers and distance is shorter than 500 kilometers. but this only accounts the 0.002 percent of globally. the issue. by 2050, the estimated could be up to 0.2 percent, which is still small. what am i talking about? carbon emissions. but this is purely electric. we're talking about equals a house versions of hybrid. so you could have a series hybrid which is where essentially fuel is used to power an electric my

to which then powers the aircraft. so you're using fuel to charge a battery, essentially. and then you also have local power, low hybrids, which is where you have the electric mertsa and the fuel source. so kerosene to hydrogen probably is being used for propulsion. i couldn't imagine this tiny p. i'm getting much bigger in the next 2 years. but the hybrid argument really makes sense . the idea estimates that hybrids would be the next leap, navigation of the 2030s, and this will contribute to a 40 percent reduction in emissions by 2050 long flights and most likely use biofuels with some possible attain electrified. and some use of hydrogen. deposition is a small step, but it gives hold for the potential of the diversity of technologies that we're going to need the coming back to the topic, the streets, florida stock key to combating climate change. they are the largest store houses of climate warming, carbon often oceans,

and yet deforestation continued economic duties across the world, including here in india. 50 years ago, women from the typical movement started and inspiring fight to save the trees of northern. we'll talk on the day of when one in uganda is using their product estimates hubs to spend to vend us on the dangers of deforestation. patricia aria cause spent 15 hours hogging this tree when disaster struck hard. a lightning strength and power cut ended her world record attempt but the uganda active as didn't give up. in january 2024, patricia hung this tree for more than 16 hours straight. and is now officially registered in the guiness book of world records. what looks like a funds don has a serious background though, and patricia wants to draw attention to it. the

the problem of climate change is huge. and at least now the world is just looking up to it. it's about time that we pick up the pace on plant histories because our natural for a sub going, we're using up the trees, not minding to replace them. a statement that is especially true for uganda, which has one of the worst deforestation rates in the world. according to the online tracking portal global forest watch, the country has lost more than 1000000 hectares of tree cover between 212022. for patricia. this last needs to be addressed. she says trees are key to facing or climate challenges. trees have a very, very know much advantages at this very moment. i'm bringing the freshest oxygen

about being the cause i'm getting a therapy for my tree. and at the same time, it's taking in a couple of dick said, just talking about 3 is not enough for patricia. she wants to help bring them back where they were lost in uganda. for this, she needs the help of upcoming generations. and a good idea to get their attention. in this case it's wouldn't pencils filled with the tree seats. these plans of, of pencils and her luggage, being active as regularly makes community outreaches mainly in schools and eastern uganda. so today, 3 education is on the schedule for this class. it's very important that they understand the jenny, they're about to take one, which is trip blunting and i want them to send the process for my c. and so this

particular thing. so for me to test seems insight and they're using it to study it . at the end of that, it's going to translate into a tree, a tree was cut and the tree is going to be planted. that is what i want them to basically understand. from this, you get the activists hopes that she can help the students to value trees more, you said, and when it took a plan to condense desk with the in the say within for you go, are you supposed to work in this school patricia's tree and planting education was well received. she has come at the right time. when i want to read you on, on the country i applied, is in need of mitigating glenn me since for we all, we all know how much our communities displaying that. pres, pens, hosting drumstick clements chain or so it is literally, in good times it takes decades until

a seed has reached the size of these trees. all the more reason says patricia to begin embracing them sooner rather than later. the way such as function would be that the post say truth, things that we should love, but this should protect and eventually planned. so you're seeing me doing this, maybe it could take something in your mind as well. you know that trays could the precious things that we work on live very, very well with such as fighting people and ideas. do you know people who are trying to make a difference on saving the planet in big or small res? like to us, you can email us or reach out to me directly on my social media handles. i will see you next week until then take care goodbye. i'm a scott the,
