i mean, the facts of climate change, i mean, felt worldwide deforestation in the rain forest continued carbon dioxide emissions have risen again. young people over the world are committed to climate protection. what impact will because change doesn't happen on its own. make up your own mind. d w. lead for mines ah, a flock of drones is lifting off, carrying thousands of seats there on a mission to plant trees and help save the climate.

with in july 2019 researchers at the swiss federal institute of technology e th zurich made global headlines, planting trees could help mitigate climate change. they said, but it would require a huge number of trees to be planted worldwide. reforestation covering an area about the size of the united states a massive undertaking. but the idea was an appealing one, a promise to save the climate with a simple act planting trees. but the initial euphoria soon began to ebb. critics included scientists who called the idea unrealistic

in germany, the university of barnes ica. luling was one of the 1st scientists to speak out skipped term some. i'm in the arab studio, i'm a girl. there are a number of questions. the authors of that study need to address is all of that land actually suited to planting trees. all in that time they see a lot of potential in the taiga, in the tundra, in regions that are too cold for trees, yawn. they want to plant trees in the savannah, which is nothing like a forest. a savannah has lots of grass land. mm hm. and just a few trees, osland miles or tanisha winter ships. and you have to be realistic if the trees would need watering, tending to muddle with millions or even billions of new trees. who's going to do that work at the fun semester? and was the human figure that is all come you run him in western australia, a huge tree planting. project is already underway. it's a landscape that isn't exactly welcoming for young saplings.

the soil is dry, the terrain is uneven. salinity can be a problem for staff members of the environmental tech start up lord of the trees. the work here is a challenge. planting trees by hand here would be extremely time consuming. that's why david tenant and mama hussein are using drone technology. a drone can distribute seeds evenly from the air quickly when it comes to planting trees, can it believes drones are the future? it's a great, big balancing act to know. can we replace the trees faster than people are destroying them? this technology that we've developed is going to be fantastic and doing that. this is really the future for saving the planet. for each

patch of land can, it creates a special mix of seeds by distributing the seeds is just one step towards planting of forest. technology is, is going to bit play a big role. and just for instance, in drones, not only do we, you know, map the area we, we are, you know, so the said we monitor. but we can actually plant, sees where in the human p as in congo, oil dangerous will happen to know a drone can so almost $7000.00 seeds an hour, a job that would take a humans 6 days, david kennett burst, planted trees here, 20 years ago. now he's testing various planting methods on different plots of land, like many countries, australia has been felling woodland to make way for agriculture. can it says that's

a mistake. ground water levels have plummeted. a problem for young trees. the mood, this is one of hundreds of varieties of eucalyptus, of drawing on the property. and i chose them specifically to be salt tolerance, which is important because as soon to such a big problem in this area, right. and also i like um, with large leaves because with the lot the leaves of the most common sequestration takes place to address climate change while it's up. but it's a double whammy david. can it only plants trees that are native to australia, they're suited to the local land and climate. non native species and mano cultures would further damage the soil. but even local species don't have it easy here. this is a bit of a sad specimen. this could seem mode that was dod. um, it could have died for variety of reasons unsuitable for the soul tide, or could be being competed for nutrient to tetra from the street. but when we're

sewing seeds, that term you'll be sewing with your drones, will be sewing varieties, which are particularly suited to the sol thought that a good thing with drones is that we can monitor. so a 2 month late a 3 month later, fly this a flight path, right? or we can tell how they progressing. now that is one and we will be able to give you a report which says that particular trees healthy this one down the road is not this drone as taking off with seats from a type of acacia tree native to the region. this technology could help plant millions of new trees. if all goes well, a new forest will soon take root. here. in ireland, new forests have already been planted, but climate protection isn't the only goal here. landowners,

such as brandon lynch and county liter um wants to harvest their trees back in the day. lynch's father was able to earn a living from cattle farming. but those times are long gone. it's not possible to make full time live unnoticed of it, of faith production. and any more, it's just it's just income as soon dropped to watch over the past 3 or 4 years. it is just not possible without a job to in a, to have a job as well as farm. lynch has placed his hopes in the fast growing sitko spruce . he's planted by hector's, of them on his land. the moist rich soil is well suited to the evergreen species. when the cisco spruce is, as they were said, the bread and bought already off of the day plantations, you have to look at the economics of it as well. and there's no point in planting something that you can't sell down the line, you know, in years to come,

when it's caught down, i hope to get anything from 8 or $9000.00 an acre for that handler, which is hex free. like brandon lynch, thousands of irish farmers have planted spruce trees for harvest. the irish government says these plantations are also a boon to the climate. it was all settled, but many environmental activists said that's not the case. and a lead from citizens initiative agrees, and they say the monoculture plantations do more harm than good not too long ago, adrian kelly's farm was surrounded by spruce trees. then the entire plantation was clear cut practically over night. it was a disaster for the soil ecology and the land now lies fallow. but there were problems even before the plantation was clear, cut with shadow and might end cuz weird the northern say, the sean said willow. the feed though good. 3040 meters out. the fee, so this was had become useless. if i want to take spend the whole and i can't

expand because as you can see, i can't go so i can't go east eda soon new spruce trees will be planted here for the local activists. monoculture, plantations are nothing but green washing their money makers. yes. but the health of the soil, biodiversity, and even the beauty of the natural landscape, don't factor into the equation. he can see here that and it's really a dead zone, like nothing grows on the 1st floor. he can see down at our feet that there is like 3 or 4 centimeters of pine needles gathered. and he can seem like, you know, living to like look, everything is just snacking off, dead and nothing, nothing lives here. it's not a place that we want to come. walk in or want to see next to us. it's no good for,

for anybody by the people who are making money. the economic arguments don't always hold up monoculture. plantations are particularly susceptible to climate change on the plantation belonging to brendan lynch. his brother, a storm did major damage. no said the wind come in, they are the helper high corner. unless the bit of pe he went grown, the fair so seemed to talk, took that little corner of a day of the rest, restless and is fairly good. it's all stand on, you know, ireland shows that more needs to be done to make the timber industry, climate friendly now, sadly from one of which wasn't finding us, he, the disadvantage of monoculture is that they aren't particularly stable ecologically speaking. if i plant only one species, it's often vulnerable to pass off the thrive on that species fair to effect allin,

their a climate stresses like drowns 14 lives in yarmouth. in recent years, what we've seen is that a forest with a mix of tree species is more resilient or seen different species provide more balance. if one suffering the other might be a bit more robust and best off. as, as i this, we all spelling theater in germany. policy makers are already putting that knowledge into action. their planting trees to help restore healthy, mixed deciduous and can never as forests, forests sequestered carbon by capturing carbon dioxide from the atmosphere. through photosynthesis, the trees transform it into bio mass. mixed forests sequester more carbon than monoculture stu, ah, today, i could do. the thing is in a forest, south, east of bon. he's carrying out measurements on various trees, a trees height,

the diameter of its trunk, and its age are an indication of how much c o 2 a tree can remove. conf. forest trees absorb less c o 2 than deciduous. once. a 40 meter spruce where the trunk that's about 60 centimeters in diameter, removes about 4 tons of c o 2 from the atmosphere. a pine tree of the same size removes only 5 tons. an oak of similar size removes 6 tons of c o 2. and the front runner is the beach at 7 tons. ah, this is a beach tree. shabby, it's hidden and i've measured the diameter of this tree at about chest height, about 1.3 meters from what was ground level,

embody the edible flesh of object. here we have about 2.31 meters for the diameter . that would be about here on summit, on the i see vows on the 5th. yeah. i mean it's 0. so i can look here to see how much bio mass that corresponds to view about 4 tons also has all my own. and here you can see the corresponding amount of c o 2 spreading the magnet. so we can assume that this tree removed something like 8 tons of c o 2 resort at law. i only, i tons here, it's why off and on, but about one 3rd of germany is covered in woodland. but the carbon sequestered there only makes up for some 7 percent of the country's c o. 2 emissions large old trees are a boon to the climate. a giant, like this beach can remove around 15 tons of c o 2. but a forest with a mix of young and old trees is most effective for any country. think on some of

our fi, imagine a forest filled with huge trees like this. then of course it seems like it would remove a lot more c o 2 arm as i went out, but of course that's impossible. this huge tree doesn't just have a big trunk with lots of carbon in it. but it also has a huge leaf canopy here. when you look at the ground here, you see what happens near a huge tree like this or not a whole lot can grow. he acts. deadwood is another important component of a healthy forest. when a tree is felled or dies, the carbon stays sequestered in the wood for quite some time. so it's still climate friendly. that's no longer true if the wood is burned. he fog assessment is mars persevered. vincy, a question is, what will happen when this would leaves the forest sacrifice? as long as it stays here, the carbon is sequestered with, if it's not a gas, it won't see power overnight through the system to p. if we let it ross,

the carbon will be released of course, movement. but we've got plans for this would unless we can make furniture out of it or wooden beams. that way the carbon stays sequestered. so the overall impact his positive con, very impulsive. i english, transformative, back in australia, the focus is on scientific research and the hunt for the perfect future forest. at the australian plant bank, near sidney emerick, mo, do wants to figure out which seed mixture works best or drone. reforestation projects with botanist gram arrington who matches seat mixtures with soils and ecosystems helps the work the weekend by going out and collecting nice aids is helping to understand not so much. now we mod yahoo to establish here it is as substitutes for

plotters but to supplement what we have and to assist, let bye diversity to my time. so i think those are way as well to integrate, due to so the to could work together. the better suited the seed mixture is to local conditions. the more likely it is that trees will thrive. but what's the best way to bring a new forest to life? emerick mo, do and his team are planning to test that in the blue mountains near sidney. their strategy is to mimic what would happen in nature. when cleared land regenerates, trees don't grow right away. first come grasses and shrubs. look at the ground cover 1st year before trips. ok. so you wouldn't just plant a tree, you have to recreate to hold ecosystem by planting native crisis. luckily, going to do to be a little shrubs fill you. i tried to smoke when you notice,

such as these, but a fries, a decent turn to shrubs, flower and room have fruits. it attracts the birds, and when the birds arrive, they all do men carry off season. guess the forest experts want to use drones and special seed capsules to mimic the way birds dispersed seeds we selected today. um those tiny sits off um indigo pharaohs trellis which is a beautiful little shrub that flowers purple when we look and we select a couple of seats that we want to use for landscape. he's the topography of the rain for ah, the wind and the salinity of the sword. it's time for lift off. each drone will distribute about $120.00 seeds a minute, a prodigious amount. when the shrubs start to grow, conditions will be ripe for trees to follow. but the path from field to forest is

a long one. with we had to india, and the state of chat has gar, near the city of ry poor. a large scale reforestation project is underway. india is the 3rd largest emitter of carbon dioxide worldwide. the country hopes trees can help change that. but reforestation programs here don't always meet with approval. the indigenous animosity people are vocal critics of the governments or radical reforestation measures. they say that the state is stealing their land, planting trees on fields that rightfully belong to indigenous communities. umbrella,

no, they can. i grandfather's and their forefathers lived on this land and farmed it. i have already shown my papers to judge in august war and i farm this land, but now they're digging holes for their plantation and knows this land is our livelihood. the rangers are just doing the bidding of the plantation owner, my mother, milton. ah, there are nearly 800 similar land disputes taking place in india, but the state and tends to plant forests across a 3rd of its territory. none the less forest rangers say the government's policy will create jobs for the od obasi people and benefit the environment. one kick armika dick, village of growth bolo, ottoman beach, from egypt shall, india has a lack of forest, and that's contributing to global warming to sun jokey. i gotta i plantations like this will make a difference security abducted duck will. it will definitely be useful in restoring

the balance of nature grow minimum income, but it may be says the hundreds ally, when i, what ammonia cultures have been recognized as a problem in india. that's why the government has switched to mixed forests with fruit and timber trees. but the out of aussie are determined to fight back the indigenous forestry laws here. give them the right to farm the land. it's a situation rife with conflict. now look at the sesame plant. they up routed it, then why do that? they took our oxen and farming equipment, so we planted these with our bare hands. the small tools took everything, the ranger keeps denying it. he says he took nothing. indian authorities built of border fence for their plantation here without asking the permission of the local and of asi community. now the forest rangers, say the on obasi deliberately destroyed the fence. they

get in get good. they've movie. they are also saying this is their sacred grow up it. yeah, this land was never used for any family plan descent. you live, there are no wealthier, i think we had no farms. no good luck. this land was reserved for forest and we were given permission to set up a plantation here. brundis income, land theft, reforestation, policies that ride roughshod over local communities. accusations like these are heard frequently here. one thing is certain, the tensions between the out of asi people and forestry officials are getting worse . the united nations is well aware of this kind of problem. climate organizations funded projects that seek to resolve such conflicts. but so far, these projects have little to show in india or anywhere else. the

out of asi remain wary. over the years they've suffered repression and discrimination. and they fear the reaper istation programs are not what they claim to be. it does have the money whose the got it. the problem is not that we cut down trees for our farm. was the real problem, is that the rangers clear cut old forests and give that land to industry when the 30 over there hollowing out the land from within their mining the minerals. one of the factories and industry are the main reason why the climate is getting hotter. and why the seasons are changing so much? oh, i thought were brought up we audi vasa protect mother earth by farming the top soil rather than digging it up with all that while i'm on the what we said the core of the earth by only making use of the outer layer and was i could i haven't let alone you're done with other developing nations are being pressure to plant more trees. but do state sponsored reforestation programs

ignore the needs of local people? i colluding worries? the answer is yes. i am a procedure myself. what often happens? what's happening right now is that industrialized countries amid endless amounts of c o 2. and yet somehow we expect developing countries and poor countries to counteract those emissions through reforestation projects. and you know, when governments decide to go ahead with such projects, or when big investors come into play, the rights of local people are often ignored, silvan, and yet our planet desperately needs more trees. something that the younger generation has also come to appreciate. here in germany, young students are planting trees as part of a school project. i. yes, my name is elisha allen, this is sandy fees. jenkinson,

my number is 800. 94 strangers elizabeth housing and lars for yawn work with a nonprofit prima klemmer association. they organized today's project rems food i its yeah, hi, dawn gwinn school. children take part in a project like this. it has a special impact and doesn't the ideas really take root. obviously, over the next years, they'll be able to observe what's growing here and they'll develop more respect in nature. but all that is hugely important and they're having fun and they're really into it it's. it's a joy to watch off one for fundamental on garcia to some very often. so when i hope it will spur them to reflect on things that they don't go to climate demonstrations here and, and stop at mcdonald's on the way home on his arms. or maybe they'll ride their bikes to school. those small steps can help make the world a better place and have an impact on their lives. less of our best on them. i thought that's the most important lesson have always loved us as misty simpson,

lanchen, reforestation projects and germany must include a mix of species. the children here are planting common oak trees and a birch called the common horn beam. like a home later forests in a flood plain like this with the kinds of species with planting today and create one of the most diverse bio totes we have here in europe. this was guns, guns. they're really special that children may not know that yet it's, but over time they'll learn more about it often. and eventually they'll realize they created something really special, comes from that experience, will stay with them with the filing by now protecting the climate doesn't always mean planting millions of trees on massive plantations and reforestation can't be a fig leaf or massive carbon emissions. some fema rounded read some not a cure all in the fight against climate change. members, few trees can remove huge amounts of c o 2 to yeah. but we, amid far more than they can ever cope window trees,

can't solve our problem is on to mitigate climate change will have to tack, allow energy use and consumer habits in all sorts of ways understand. simply planting trees is not enough to combat climate change. but done well, reborn station programs are a step in the right direction. mm hm. ah, ah, ah. ah, with
