to speak of how critically nature it is for also vice. hello and welcome on. so i've got 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 autoland. it is an experimenter, 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. some people that 3 doctors trying to look off to each and every one of their patients they look like number petered out with heavy 10 souls harnesses, fuel canisters and has but rather than setting 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 beam of experts tend to its green reading branches. 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. this such a different view and experience that 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 petty 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 fall for the storm in 2011 greek have and resident a got their full cause is young and she was destroyed by the port 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 and i say it was very loud to you. you see that it's growth from 2011. and this is the it was as soon as 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 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 everything that typically come into the picture once it is already affected by this or damage. even though trees can be surprisingly, adoptive in oven, and ones that are often susceptible to disease, andrew 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 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 means 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 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 device beyond the tree tops of our old yard. and in the cities, millions of monkeys and cos room, the streets with no access to the water or shed. these 3 suffered exceed that events that are becoming more frequent because of human and used climate change. we might the women 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 the. my name is i may have been town man on the founder and president all for ask your child to be addressed. i would call you myself and what address to your specialist? i'm a born and brought home by going and that's it. all i saw it on me were dogs and got some bugs. 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 taught 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 last year, getting into the road accidents. so that's when we started doing more lodge on the move up in 2007. when i started, there was literally nobody providing emergency services for any kind of on the move or either a screen and on a move on for you, or you bringing the animal into the skin center because it needs additional help. so it's good for here where it's undergoes, do you have a dish and then is it going to be introduced back to the right and or the 3rd situation you kind of respond to is um, you know, a contract situation where you're trying to mitigate, mitigate, or conflict that's happening, know that for example, could be um, you know, maybe uh, leopard made a live stop kids and people are angry,

you know about it and you're trying to mitigate that. the after vention activities are focused on community awareness education. the big guy has a couple of friends trying to do good for the animals in the world. what you see today is the 1st responders. you see, do you have the data? as you see yvette 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 99 volume. and the, one of the visions that i have is to develop

a network of remote squads. um and this basically means to provide employment doing okay. people who are passionate about guns 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 issue that expanding in many countries, including india. it is also one of the fastest growing sources of greenhouse gas emission. it generates the avenues in android. but does that mean we stop?

well, that seems limited by the fire hotels in our shop on electricity. then why contact me? my colleagues, i just need as a go back to the sky is reading it won't surprise you to hear that how we fly to the 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. 3 is why are you what is the most promising solution? so a vision, pollution of biofuels, a more broadly sustainable aviation fuels. they're mostly made from non petroleum products like bio mass. 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 with the scaling up is very hot, and the land could be used for other purposes like throwing fluids of 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 where we know we're on off hydro power or wind power. so then a consider we have is, is sustainable and renewable. so for us that's, that's the, the most sustainable we can do. right now, so the for us, this is you on know, but as going to of 80 ition and one of the only people flying eat planes every day . when a vision school in sweden where future pilots are being chained and flying electric lands. the biggest student, ballast, they fly here doesn't need much electricity. it takes around an hour and a half to charge on which has been 545 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 on the same time. so i get faster tough to get in.

so ask 1st, it's easier. i'm ready. all right, let's go 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 of face with a big problem. heavy batteries blowing 747 to fly from say, london to is done with batteries will need to be this much heavier than a full time. this just cons works and this would 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, gary, 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 jessica, what was it all started with the design off in 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 this trip over time, 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, but they have a 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 various type plans. so governments and many of the industrial going back to the drawing board to redesign this is dawn bought 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 edge 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 batteries. 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 that was required and you 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, a site of the 2 systems we, we favored the battery charging system. but we were very aware of the potential limitations, but that could price. so not easy. the now i mean you can find if you want. so what do i do

if you want to know if it go down for cystic ford, if you want to think back to this shows what the 1st change to be certified. but this is another huge challenge, ition has compared to cause being certified for safety. so everything takes time for r and d testing including for battery safety and the use long certification process. but this january the yorba in solomon bush with 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's been made that the district is now working on a faulty dublin. and the already big ones, a plane called olive secretary, 9 passenger, the 2 crew members seem to be close to commercialization, promising to fly around 400 kilometers hot aerospace and sweden has a proof of concept aircraft that good 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 child has or the 12 plans for low emissions postal deliveries, which can help local noise and quality to a study by the international central and team evaluation estimates. the electric aircraft could cover 9 percent of the coming to markets that slides with more than 19 passengers and distances shorter than 500 kilometers. but this only accounts the

0.002 percent of the company issued 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 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 play and 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 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 of trees, florida saw key to come back in climate change. they are the largest store houses of climate warming, carbon after oceans, and yet deforestation continues economic duties across the world, including here in india, 50 as a goal, women from the tip, almost months stockade and inspiring fight to save the trees of northern today. and when, when a new gun dies using their proc estimates hubs the spread of n s on the dangers of deforestation. patricia aria calling to spend 15 hours hogging this tree when disaster struck hard. a lightning strength

and power cut ended her world record attempt but the uganda 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 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 grieving the freshest oxygen program being the cause i'm getting. it's eric from a tree under the same time it's taking in a couple and dick's age. 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 as

these plans of a 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 to read the 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, at the end of that, it's going to try switching to a tree, a tree was cut, 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 they talk of planting events, dest, which then they 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. when i read you on, on the country, i flags is the needs of mitigating climate scenes for we all, we all know how much our communities are displaying that freeze tens hosting drumstick clements change. and 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 people say trees, things that we should love, but this should protect and eventually planned. so you're seeing need to have 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 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 a scott the, it's the
