the what can we do? carry on and some last day, a nice, the nice you get their hosting for larry king and david shudders august 3rd on d. w. the, on the show we often speak of pol, critical nature. it is for all survivors. hello and welcome. i'm sorry that got the body and you're watching equally and do. 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 autoland. it is an

experiment, a 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 simply books that 3 doctors trying to look after each and every one of their patients. they looked like number figured out with heavy 10 souls harnesses, fuel canisters and has but rather than selling trees these men on a mission to save here in the south indians don't ship of a row with every 3 guns. that's why a homegrown team of experts tend to it's green ribbon granted. when i was young, my father had a friend who was starting to build tree houses. so as a sample they build one in our backyard. there's such

a different view and experience that you get and 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 ira woods, priest together to join us. so shown the founder of maintenance company, pre k. they both grew up here and witnessed the community's 34 decisions efforts. done this one's about in region 2, a lot of green landscape, the transform ation and stairs and them a lot for new to which that down into the profession arborists or, or our board culture is it comes from the latin word arbor, which is 3. 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 select loans. these are growing most frequent due to human induced climate change. a buffer, 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 code to in to paul. and i say it was very loud to you. you'll 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 to damage. i luckily, the expert a tree get solutions on 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 uh, force that closer again. but even with the best of both, its gone save every 3 that typically come into the picture once. it is already affected by unless or damage even though trees can be surprisingly, adoptive in oven,

and ones that are often susceptible to disease and root damage. the island let's go is an auto with 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 side 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 urban green trees resilience through this process of changing climates such as drought, as well as to pollution and lots of biodiversity in the open nickel system. or when scree doctors are always on the lookout for early warning signs of

a strict. 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. let me make sure it's in the last, it's 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 body, bump up the local conditions. it's june us so shall next folks that use new crops of practitioners will help us spread a sensitive a pro se claimant. the rise 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 show these free software to exceed the events that are becoming more frequent because of human and used

climate. change, we met the woman in point a who was who just by that's life, that she decided to take action. a step that benefits many times will find dynamos today that says spaces with the, the main starting point to sort of started 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 them 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 us north or band was enforced. nobody talked of the off the month 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 foster getting injured or 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 hope. 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 thoughts situation you kind of respond to is you know, a conflict situation where you're trying to make the 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're know about it and you're trying to mitigate that. the raptor of engine active it. these are focused on community oven is 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, in 99 volume in 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, on the best part is when you would use them back out. they don't even don and look at the issue and that 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 hotels in our shop can walk on electricity, then why contact me? my colleagues, i just need as a go back to the sky is 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, what are you? what is the most promising solution? so a vision, pollution, a biofuels, a more broadly sustainable aviation fuels that mostly made from non petroleum products like biome on so out 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 scale up is very hot and the land to be used for other purposes, like drawing fluids or saving floors. 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 where we now have we, we run off hydro power or wind power. so then it just said it, we have is a sustainable renewable. so for us that's, that's the demo sustainable. we can do right now, so 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 with an a v as in school, in sweden with future pilots, i've been chained and flying electric cleans the papers for the ballast. they fly here, it doesn't mean much electricity. it takes around an hour and a half to charge on which has been fly 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 hoss 1st, it's easier i'm ready, correct. i've got the . 7 as 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, how does the app, what's program at the u. s. department of energy use, national renewable energy lab 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 hulu. batteries, they have very poorly coming in at only 2 percent. but conventional aircraft to be flying today. i've been as for jessie, was it all started with the design or from the 1950s?

they've been propeller plans the most popular at the time until by an engine 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've 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 this trip over time, this though bye in or cuban wing design became vastly more efficient. okay? we know if the race, today's deadline has been almost 50 percent less fuel passenger kilometer than the did 50 years of, 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

bug and a vision expert who 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 ok, 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 the 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 would 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 off of the 2 systems we, we favored the battery charging system. but we were very aware of the potential limitations, but that could pose, so not easy. the now i mean you can find if you want. so what do i do if you want and also go down with the purchase order. if you want to take it back to the sales with the 1st plans to be certified, but this is another huge out and what evaluation has compared to cause being certified for safety. so everything takes time for our in the testing, including for battery safety and the use long certification process. but this january the yorba in solomon bush for the idea of more

e plans for shot and mid range flights. they just bought of a while ago to got 90 percent of emissions from transport by 2050. all right. thank you. all those crazy sit on the equity. okay. the company that means that the district is now working on a full cedar plan and the already big ones. a plane called olive secretary, 9 passenger, the dooku members seems 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 their only connection is a, as a 9 senior crap. unless they take a ferry for or 6 hours type of 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. and 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 smaller across the child has or the 12 plans for low emissions postal deliveries, which can help local noise in a quality to a study by the international central and team evaluation estimates. but electric aircraft could cover 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 for 0.002 percent of global deviation. 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 they have 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 a cool power low hybrids, which is why you have the electric lights up and the fuel source, so kerosene to hydrogen, probably is being used for propulsion. i couldn't imagine this tiny pan getting much bigger in the next 2 years, but the hybrid argument really makes sense. the idea estimates of hybrids would be the next leap, navigation of the 2030. and this will contribute to a 40 percent reduction and emissions by 2050 long flights and most likely use biofuels with some possible attain electrified, and some use of hydrogen. the petition is a small step, but it gives us hope for the potential of the diversity of technologies that are going to need the coming back to the topic, the streets, florida saw key to come back in 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 tip homeless months started uninspiring, fight to save the trees of northern. today i went in uganda is using their product estimates hubs to spend to vend us on the dangers of the for the station. patricia area cod spent 15 hours hawking. this tree when disaster struck hard, a lightning strike and power cut ended, her won't record attempt but the you can't, in activist 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 age 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 plants. this tree is 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 probably even though our because i'm guessing it's eric from a tree under the same time it's taking in a couple in dx aid. 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 of the what these plans double pencils in her luggage being active as regularly makes community outreach is mainly in schools in eastern uganda. so today 3 education is on the schedule for this class. it's very important that they understand the generally about to take one,

which is trip planting and i want them to send the process for my c. and so this particular thing. so for me to test things inside and they're using it to study it at the end of the day, it's going to try switching to a tree, a tree was cut on the tree is going to be planted, and that is what i want them to. basically understand from this, so you get the active as hopes that she can help the students to value trees more and say when it took a plan to convince desk with the, in the say within for you go, you're supposed to what in this school patricia's tree and planting education was well received. come at the right time. or when i read you on, on the concept lies, is the needs of mitigating climate scenes for we all, we all know how much about communities displaying that, pres? tens hosting drumstick clements change. so it is

a really good day and 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 people say trees, things that we should love, that they should protect and eventually planned. so you're seeing need to have these. maybe it could take something in your mind as well. you know that trace 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 drive 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
