i come to take talk with them about hackers and paralyzing between your societies computers and i know some are you and governments that go crazy for your data. we explain how these technologies work, how they can go in for but how they can also go terribly. watch it now on youtube. ah, we live in a world of finite resources, and yet we pillaging the planet like there's no tomorrow coming up, echoing yet discovery, the been joseph,

feeling capital from nature as well as ways to manage the assets on which all our lives depend. hello, welcome. on front of that, i got some raw materials could be exhausted within decades if we continue extracting them at the cotton treat that will drive up prices or construction. for instance. the industrial relies on sam for materials to build a booming city. but sand mining has a dramatic environmental consequences, as we've discovered on my soul. mm hm. it's just before mid day, when a small fishing boat approaches to show me among bye. but the men on board, on making a living from fishing as their fathers and grandfathers did. mr. devon pulling sand out of the sea, bucketfuls after bucketful. among them this jerome channel,

he can dive up to depths of 12 meters. when he started 20 years ago, he was just the person who hold the buckets on board. but then he started diving. the spending of the firewall was in the water doing dive after dawn. good, mill protective equipment and no oxygen tank bigs, dangerous work on the go. i go into the water with the pipe in one hand and the bucket in the other. we hold the pipe with our legs and used a bucket to dig outside. i thought of avi, i have and then the people on the boat pull up the bucket. i come up by holding the pipe, the empty the bucket into the boat. i give it back to me once and then i dive again . it's all in love you by the delicacy of north madison facility. this coastal region has a decades long tradition, not pulling sand out of the sea, but using construction. the problem now is the scale. several 1000 people are

living in by mining to see for son says activist. so mary of de la lee. she has been campaigning against legal st. mining on in years. goals for more than 10 years has a lot of adverse effects on environment. but of course, it also has effects on the community because although they don't realize it, the sun mining is destroying their fields and their livelihoods, and making their fishing livelihood loss was by actually reducing the amount of fish catch. it's also because it's taking away the medium which holds the river, the creek on the beach together. it's also making land more vulnerable to land loss . meanwhile, the demand for sound is growing as raw material for the construction industry. since 1990 mom boy's population has more than doubled to almost 21000000 people in 10 years. that number is expected to grow by another 5 and enormous growth needs

sound in the waters all around mon, by st. mining is prohibited but illegal. st. money is a trying business. what 1000000000? that's what makes samira up the lollies work so dangerous. she's been brutally attacked twice, was speaking out publicly against illegal send money. but she hasn't led the stopper. i was in hospital for a little bit. and her, of course, the idea was to frighten me and make me stop complaining. but for me it was the other way. i felt that if somebody is taking it seriously enough that they actually willing to do physical harm to somebody. and particularly a woman in full side of the village who all pretended to be asleep while this was happening. then surely, there is more to it. together with her, a vase foundation of the lolly done to the united nations to raise rent as of legal

and mining. and the you and environment agency has declared sander with the world 2nd most exploited resource. often water was up to 50000000000 dance used each year . in other words, or result in need of governance, rivers doesn't cost lines are being destroyed in the search of sun, and good them, the habitats of plants and animals, as well as natural flow barriers. at the indian institute of technology bumper researches are looking for alternative materials for the construction industrial. she arm also lick who has been looking for a sand substitute for years he and had the students have funding. he found one in decades, all the garbage the good outcome of that, the search was that media lays after eating what remains is nearly all useful. and then if we really go and mine those aids landfills, which we call in india,

legacy landfills, that legacy solid waste can easily broad be processed at that location. and then vaccinated into video essays, vaccines, and the fractions off had ms. dr. that'll be separate, just like some loss the solid waste can be used in a multitude of different ways on building sites. so this can be built very quickly . i would estimation is that between 5 and 10 percent, my bill only needs to go through the landfill. among the entire solid with that is generated in a given location and, and, and, and anywhere between 90 and 95 percent material can be put into several recycle and then can work dead and refurbished into various other construction model and substitute which can go again back into the construction industry, it will take time until rest can replace sanders of all materials and pursuing on vice sun divers to give up their jobs will be no easy task. a direst made

a 1000 rupees around 12 heroes a day, a bucket. pl again and 400 rupees. much needed income for several 1000 families. it's impossible to go and stop at overnight. there will be a many problems with something like that. you know, you would, you would have a problem in meeting the needs of the country in group, in growth. you would have a problem in providing alternate livelihoods. if it was done overnight, over the next 25 years. if you want to invest $1.00 trillion dollars in infrastructure projects for its growing population in its growing city, that means no shortage of work for the sand. divers of mom buy and even more damage to in the us marine ecosystems. the catalino and the community that is spearheading and drive to conserve the wetlands that it relies on and that thousands of species call home. it's located on one of the most. we're new to leaks

in the world to a series of initiatives. locals now have their site set on becoming a model. wetland village. ah, only half an hour to go before school ends in another. but at this government school in bahama, in the southern indian state of carola students are still hard at work. ah, you know what? we're going to do, we're going to make a bag and use it when we go to buy rice. tell your mother not to buy any plastic bass. tell her to make such bags losing old clothes. we should save our environment . right a little can. it's not just another lesson in

math or history, nor is with their understood, had their teacher. she is here as part of a new program to train students on how to up cycle old clothes and make them into clots backs. with if there has been stitching clothes for years now, but it's only in 2016 when she was approached and given training by her bad child and non profit, a shocker trust and ecology and environment. all 80. that she decided to switch to making bags, pillowcases, and sanitary pads from old clothes, collected from homes, schools and colleges. since then, she, along with this small crew of women, have made close to 6000 cloth bags from around 2600 cages of used clout. for the women, the benefits have been multi fault. but of, i'd love to learn that a lanka to have been so many changes in our lives. and even though it's small skew,

we get an income from this. we also get to meet more people and get to know more things, but it gives us a lot of happiness and mental peace. i've said under then i let us on darcia my liver further. it does need a village, mamma in allah, for our district lies along them. bernard lake, the longest lake in india. and for years, she has witnessed pollution in the lake getting progressively worse being part of an initiative that reduces the number of cured dumped into the lake while also helping me alternatives for plastic bags seemed meaningful to her said to her and her. but though, now i lebanon, my husband breaks in the lake, he collects clamps for a living. but then when he comes back with plans seeking, we see a lot of plastic in it. every time he comes back and each he will have 2 or 3 plastic items in, in the loaner. they are always bottles and plastic boxes. there is no control on how people are dumping plastic and garbage into the lake, florida lake and i live local allen. it's also

a lancer site, meaning it has been designated a wet land for international importance by unesco. but the lake, which serves as a lifeline for 1600000 people, is also one of the most polluted water bodies in the world. a recent study found high levels of plastics and micro plastics in the league decks, dias and glass are also media sources of pollution. pesticides used in nearby paddy fields, also trickle down into the water. joking the rich biodiversity that exists in and around it, for in muhammad, a small village, with a population of $25000.00, the impact has been severe while young, over oh, lord, abundant had got the load barn along had been to my production of glands,

is decreased or the production of fish has decreased over the production of the bronze has been had badly guy alive. and all of this had affected the people who depend on the lake for the livelihood. and this had begun an issue of the survival ever did. i don't know that the law he thought of another it under the situation was dire when the oliver a branch of bangalore based nonprofit 8. she approached the punch it in 2016 with an idea. make me huh. a model. wetland village. under the project, a wide range of initiatives including the up cycling enterprise, were launched. the all on work, those involved with maximum community participation. we believe in an inclusive form of management. so actually for this project or so we made sure that the local pin giant, these partnered with us along with the health department and the, ah, ah, other community based organizations in video. so i think that maybe that that should be one reason or that partnership made it happen. ah, the of us won't be good,

was tremendous. that response was the highest for another initiative which made mahatma in this 1st synthetic sanitary bag, free village plastic beast pads that end up in the lake were found to be a major source of pollution in the village. with a survey finding that $7000.00 menstruating women and will hammer use up to one lack sanitary pads a month ever since, they were distributed unsubsidized traits been the switch to using cloth pads, and menstrual cups. dad and younger body. and they've got by the guy and we saw the cups for the 1st time. we were scared to me, but now that we have started using it, we can't do without it. i'll go on the thought it was very helpful for us during flood sap. but then after using the cock, we can dry them inside the way jam crossed paths have to be dried outside and unload and up a layer with the cops. and we didn't have to worry about anything when it rings and flood ca. i know

a good that can lead america naughty and they don't despite the funding received by ici, ending in 2020, the project continues to live on with the n g or support. and the punch i've leadership for the residents here. continuing to set a model in wet land, conservation is as important a task as protecting and consulting. the lead that nourishes and 15th them are hungerford raw materials has scarred landscapes around the world? from storm quarries and india's o'dee shall state that moved into hillsides to the gaping hole left by germany's open feet, lig knife mice for what can be done with these regions once extracted practices. in a former industrial hub, near berlin, off was hope of a total transformation. the east german village. of course. caution is bustling with some of visitors. it's just 150 kilometers south of berlin and not far from

the polish border. the bikes offered at a cat hoist rental are in high demand with visitors came to explore the region as well as outside of the sink. cedar is finally going for it's been, it's been idle. old i wikker started his business here 20 years ago. back then no one believed that this region off lu, sasha, or louse. it's as it's known in german, could attract any tourist at all. the area was solely associated with a bronco industry. it was a mood landscape like this. the locals thought echoed hoya was crazy. down below to get fog for us must den sites the lawyer you reach out. people kept asking, what do you do? shows people the whole. so the mood was different. back then evolve. there was still a lot of the pitts from the other natasha mines. i thought some ball today locals are proud of what's happened here is i'm sure once you receive the vast

open pits are gradually being transformed into europe's largest lake landscape. once complete, the lu zation lake district will cover 350 square kilometers. it's helping louse, it's transform into a green holiday region with broad cycling lanes. hotels and landmarks like the rusty nail, which serves as a reminder of the regents industrial passed from the top of a tower. visitors can observe another new lake in the making. the former open cast mine is slowly being flooded by ground water. this is showing vast biz and was we out. it's really something special there. got, i mean my, how many people can show you a common, likely new landscape hog lots of rooms as well. if everything goes as planned, this will be finished by 2025, god willing leave us the show has been developed and stabilized over thought. there's still some work left to do over there and all that should take another year

or 2 though on in its prime the coal industry and allows its employed 80000 people. but in the late 19 ninety's, the energy sector and germany was restructured. dozens of unprofitable minds were closed. 90 percent of the work has lost their jobs. one in 5 people left the region . only for open cas mines remain active in laws it's to day. but that days on them, but to germany has pledged to face out coal completely by 2000, said he 8, transforming this mining landscape cost the german state upwards of 250000000 euros last year alone. between 199-220-1610 point 2000000000 euros was spent. lime needs to be at to the lakes to ensure they are not to acid, equal wildlife, and full swim us. last year, more than 30000 tons were required to balance p h levels. then there is

maintenance and risk assessment work carried out by g. u and genius, like philips auto is his job to ensure that there are no landslides, after decades of digging, the soil is more loose and can be moved more easily by groundwater if it rises quickly and a crew switch. oscar luther, which is huge wave was triggered artificially so that land areas could be moved in a very effective way if there's a landslide happening underneath moving further and further back them up. and it's these forces that create the sudden wave on his india at the bottom here, we see trees are knocked over like match tanks. there are very powerful forces that work. all of them isn't good bye to a customer. officials only one to these kind of land slides to happen in control circumstances in 2010 this area. so a natural landslide, which is why entries now unauthorized back then several trucks were drowned in the tsunami like wave that drive us only just rescued in time.

the. um, i'm gonna this work will take generations. we still have to make 30000 hector's of land safe as part of the basic reconstruction work. we need to develop certain technologies, like non invasive blast induced compaction to strengthen the soil. the transformation from what the landscape once was to what it is now is radical, and there's no blueprint on how to do this work. a 30 minute drive away in an area known as greenhouse of a 3000 animal and plant species have found a new home. it's become a hot spot for bio diversity. and so yonder stella come here, we can see how nature is re conquering the land on its own that without human hellboy, it ornamental issue. this location has developed particularly well specimen, standard dots,

which i nod it up. the at the one species has grown up here that is common in germany. it's bush grass landed class. definitely a shy it is one of the several ecologists who proposed to not intervene here in dispatch, but to just let nature to its own green naturalization. under try conditions on soil that is still acidic and low and nutrients, so many flowers and now thriving here. when you come on visually, song, this process is definitely taken around 1015 or 20 years of g. l 20 yog posted. so it requires a lot of patience flesh. i'd seized the project as a success. this to 1000 packed a patch of land in louse. it's one of many former mines is now a wild natural habitat either natalia says, or when i'm his cooking, obviously it's an enormous gift to have been able to observe this change over the past 20 years at the same site. and i thought fust and asked him, spend a mark,

vinny from the start and victim bull button. and i've seen that what we envisioned as cone true struck with your involvement yet suzanne, the us are above i did system all. another vision that has come true is the transformation of louse. it's into a tourist destination that combines green spaces, full leisure and an industrial past that visitors wanted to learn about b, it on this old convey a bridge now surrounded by parks of renewable energies. does us lexi or honest guide it to a, with people who are born here, like a cat hika. he observed the rise and fall of the brown coal industry for himself. and he's still shocked by the devastating impact that the last few mines left and now's it's are still having on the land in gordon, the good norm zia, if i see it myself at the landscape, was being destroyed. thus,

i hope that someone will develop better storage capacities for renewables to increase their uses. was this over exploitation was not the future than the martin . this between 40 and 45 percent of germany's energy comes from renewables. fossil fuels like brown coals, still play an important role, but the country is now paving the way for life after the cold. gemini has created a blueprint that could be of useful other countries like india that still half that path ahead nor bad as the environmental damage caused by a growing material use more obvious than in the case of plastic pollution. as we seek more efficient ways to manage our resources, finding alternatives to plastic is keith. we met an engineer and tom allot, who's developed substitute products made from agricultural wrist.

india generates approximately 3 and a half 1000000 tons of plastic waste per year. what's more, researchers say that the per capita figure has doubled in the past 5 years. tackling this growing problem requires the development of environmentally friendly substitute materials. callian kuma and his company came up with a very useful idea. they built the machine that uses 15 different types of biodegradable agricultural ways to make food containers their mission new and within that on the symbol barbara from durcan, we gave the machine a simple design. i mean, you go that there is a very little training, is required to operate in that owner. alabama. do companies buying a machinery? just need to choose the raw materials on monday and we will help them mix the raw material based on what, which hardly takes a minute. no, no, on one nor once the machinery is on it long. it takes 40 minutes to heat up their reality. raw materials are added, but i of the diet cavity they go de la, loading and unloading are controlled by the lever. only want to control the when we

unload after 3 minutes, the cups and containers are finished up on the fall might look the burning of agricultural waste leads to serious environmental pollution. and that in turn leads to worsening health issues among the population. but farmers could make more efficient use of the waste coconut fibers straw, tamarind nuts and tea and coffee. i used to make biodegradable and products oh bono. thankfully alarming it did. la la, the agricultural waste leg rice and paddy's draw. it can be managed more efficiently. allow me to think currently it's either burned or crushed down and reused as fertilizer ended with an avalanche. this can be highly profitable when done right. when he bought the water, my, my, most of the farmers do not know what to do with the excess strong adjusted i. then with no i go learning anything. we certainly need to create awareness about this whole process. another i'm will alone. only go thing on the alone, i can invent machines,

but the real challenge lies in driving the whole process to make sure equipment is available to the farmer and then i'll go, okay, look, well bailable theater, milligram condo on the machine to santa, from co, inventor strongly believes that the real push must come from consumers. they must be the change makers of blasting care, but broadly allow, in spite of the government's ban, unclasped eggs and now we can see what's commonly used on a day to day basis. or we can blame people for that life. they're going to buy the things that are commercially available, either model and we have to provide substitutes so that plastic usage can be gradually halted and other on they do have we really come across alternative tea cups at any near by star i the garden, the reality is that we are not efficiently managing ways, but above and there are raw materials available for producing sustainable and eco friendly products on a daily longer vessel. these biodegradable cups are at least one step in the right direction. now as coloma just pointed out,

using raw materials which are sustainable is the need of the hour. remember, there is no planet beat and it falls upon us to secure the future of those who come off to us. i'll leave you with that and see you again next week. good bye. and thanks for watching. a blue blue with
