and how does it taste? it's like the real thing. yes asked. will we all be beginning 50 years? i literally think that legs are the next generations. well, i'll look back and say, that's crazy that we ever use animals to get a documentary series about the future of food. and there were complex relationship with animals for the great media debate this week on d. w or ah, we live in a world of finite resources, and yet we, pillaging the planet like there's no tomorrow. coming up the coin,

yet discover the dangers of stealing capital from nature, as well as ways to manage the assets on which all our lives depend. hello, welcome on front of that. some raw materials could be exhausted within decades if we continue extracting them at the country that will drive up prices of construction. for instance. the industrial relies on science for materials to build a booming city. but sand mining has a dramatic environmental consequences, as we've discovered on my soul. with it's just before mid day when a small fishing boat approaches the shore near mom by but the men on board, on making a living from fishing as their fathers and grandfathers did. hey, mr. they've been pulling sand out of the sea. bucketfuls off the 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. dick mil protective equipment and no oxygen tank. it's dangerous work. well, on the day 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 out sam glass of ivy. i have and then the people on the boat pull up the bucket. when i come up by holding the pipe, the empty the bucket into the boat. i give it back to me and then i dive again. just tell them what the hell is the up north midway is delivering this coastal region of the decades long tradition not pulling sand out of the sea, but using construction. the problem now is the scale. several 1000 people earn

a living by mining the sea for sun, says activist. so mara, abdullah, she has been campaigning against legal st. mining on in years calls 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 my actually reducing the amount of fish catch. it's also because it's taking away the medium which holds the river, the creek, or the beach together. it's also making land more vulnerable to land loss. meanwhile, the demand for sand is growing as raw material for the construction industry. since 1990 mom wise population has more than doubled to almost 21000000 people in 10

years. that number is expected to grow by another 5 me and and remind growth need stand in the waters all around one by send mining is prohibited but illegal st. money is 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 worked 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 a renters of legal and mining. and the you and, and violent agency has declared sander with the world. second, most exploited resource after water was up to $50000000000.00 tons used each year. in other words or result in need of governance. rivers doesn't cost lines are being destroyed in the search of san and with them, the habitats of plants and animals, as well as natural flag barriers at the indian institute of technology bumper researches are looking for alternatives materials for the construction industrial she arm also lick has been looking for a sand substitute for years he and had the students have found that you found one in decades old garbage. the good outcome of that, they said 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 brought the processed at that location and been vaccinated into media sites, 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 they skin to very quickly. i would estimation is that between 5 and 10 percent, my deal only needs to go through the lengthy, among the entire followed with that it ended in a given location and, and, and, and anywhere between 90 and 95 percent material can be put into several recycle and then converted and refurbished into various other construction material and substitute which can go again back into the construction industry. it will take time until raced, can replace sign as of all material and pursuing mom buys sun divers to give up

their jobs will be no easy toss. a diver is weird. a 1000 groupies around 12 year olds a day, a bucket bullock and on 400 rupees, much needed income for several 1000 families. nits impossible to go and stop at all the night. 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 products 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 years 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 nonprofit. i shook our trust and ecology and environment all eatery, 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 fold. but of i'd like dental and at a lanka to have been so many changes in our lives. and even though it's small scale,

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 the osha and hipaa further bid. there's made of village, more hammer in olive or our district lies along than bernard lake, the longest lake in india. and for years, she has witnessed pollution in the league getting progressively worse being part of an initiative that reduces the number of fluids dumped into the lake while also helping me alternatives for plastic bags seemed meaningful to her. said a calendar. but though now i live near my husband, works in the lake. he collects clams for a living. but that when he comes back with clam 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 the lona, there are always bottles and plastic boxes. there is no control on how people are dumping plastic and garbage into the lake,

florida lake. um 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. deck styles and glass are also media sources of pollution. pesticides used in nearby paddy fields also trickle down into the water. joking the rich bio diversity that exists in and around it for in muhammad, a small village with a population of $25.00. i wasn't. the impact has been so yeah, i yeah. how little oh lord, abundant had got that old one and i'm going into my production of glands is

decreased. the production of fish has decreased, towed by the production of bronze, has been had badly guy alive. but 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 la hollow, he thought of another into the godaddy. the situation was dire when the oliver branch of bangalore based non profit ha approached the punch it in 2016 with an idea make. mm hm. my a model whitland village under the project. a wide range of initiatives including the up cycling enterprise were launched. the all, all worked, those involved with maximal community participation. we believe in an inclusive form of management. so actually for this project or so we made sure that the local fungi, these partnered with us along with the health department and b r a 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, 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 lac sanitary pads a month. ever since they were distributed unsubsidized rates been though switched to using cloth pads and menstrual cups that the young lady at any of the got by the can. 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. um, it was very helpful for us during flood stuff, but then after using the carpet, we can dry them inside the way. cross paths have to be dried outside and unloaded upper layer with the cops and we didn't have to worry about anything when it rings

and flood ca. i know a good i can lay down well go naughty and belly don't. despite the funding received by ici, ending in 2020, the project continues to live on with the and your support and upon chives. leadership for the residents here. continuing to set a model in wet land, conservation is as important a task as protecting and consulting the league that nourishes and 15 staff are hungerford raw materials has scarred landscapes around the world from storm quarries and india's already shall steve the food into hillsides to the gaping hole left by germany's open feet like mice. so 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 summer visitors. it's just 150 kilometer 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. what is that side of the 16th or 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 of lou, sasha, or louse, it's as it's known and german could attract any tourist at all. the area was solely associated with a bronco industry. it was a moon landscape like this. the locals thought, echoed jolla was crazy. down the road to get fog was must done sites the lawyer, utah, people kept asking, what do you do? shows people the whole. so the mood was different back then, the wall, i was still a lot of the pitts from the ivan cast minds, which i thought so all the from today locals are proud of what's happened here is

i'm sure it's francisco garcia of 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 transformed into a green holiday region, with broad cycling lanes. hotels and landmarks like the rusty nails, which serves as a reminder of the regents industrial past from the top of the tower visitors can observe another new lake in the making. the former open cast mine is slowly being flooded by ground. water is showing vast. bizarre without its really something special. my god, i mean my how many people can show you how come unlikely new landscape hardwood. so for example, if everything goes as planned, this will be finished by 2025. god willing leave us to show us been developed and stabilized over felt 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 full open cast mines remain active in laws it's to day. but that days unknown but to germany has pledged to face out coal completely by 2000, said he 8, transforming this mining landscape. cost german state upwards of 250000000 euros last year alone. between 199-220-1610 point 2000000000 euros was spent. lime needs to be added to the lakes to ensure they are not to acid, a, quote, 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. engineers like phillips 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 the crew swish. oscar luther, which is huge wave was triggered artificially. so that land areas could be moved in a very effective way. there is a landslide happening underneath moving further and further back. and it's these forces that create the sudden wave. because in you, at the bottom here, we see trees are knocked over like matched eggs. there are very powerful forces at work. all of them isn't good bye to a curved armoire. 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

zoo. nami, like wave that drive us only just rescued in time. come and go. no, his 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, induce 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 in 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 by a diversity. and so he and our stella come here, we can see how nature is re conquering the land on its own without human hellboy. it ornamental fisher, this location is develop particularly well. it's better on standard thoughts,

which i nodded up the at the and one species has grown up here that is common in germany. it's bush grass lun type class, stiff, unclear, 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 and what is that many flowers and now thriving, here will your commands the shirley songers, the processes definitely taken around 1015 or 20 years of g o, one at yahoo, comported so it requires a lot of patience lash. i'd seized the project as a success this to 1000 tact a patch of land and louse. it's one of many former mines is now a wild natural habitat as a natalia and i am his cause. hang. obviously, it's an enormous gift to have been able to observe this change over the past 20 years. civil suzanne at the same site and i don't fuss than to ask respond,

and i've been here from the start and picked on bull button. and i've seen that what we envisioned as come, true, struck with your vow. and yet suzanne, the us are above. i'd insist on all another vision that has come true is the transformation of louse. it's into it tourist destination that combines green spaces for leisure and in industrial past that visitors want to learn about be it on this old convey a bridge now surrounded by parks off renewable energy's. does us like see or honest guided 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 minds left and now's, it's a still having on the land in good 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 or not the future than the mountainous 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 key. we met an engineer and thumb allowed who's developed substitute products made from agricultural rift.

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. kaleon 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 perversion did we gave the machine a simple design. i think that there is a very little training is required to operate in gonna 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 or once the machinery isn't it long, it takes 40 minutes to heat up. very, i think raw materials are added, but i of the diet cavity, they go deal 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 at the burning of agricultural ways 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, vanessa de la la. meaning 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 as 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 when i go learning it, we certainly need to create awareness about this whole process. mother, i'm all alone. the only go thing on the alone,

i can invent machines the but the real challenge lies and driving the whole process to make sure equipment is available to the farmer and then i'll go, okay, look, well bailable theater milligram combo on the machine to santa from co inventor strongly believes that the real push must come from consumers. they must be the change makers, a blast, the good barber product, they alone invited the government. then we can see what commonly used on a day to day basis. we can blame people for that. they're going to buy the things that are commercially available tomorrow we have to provide substitute so that plastic use it can be gradually halt and other. i know we really come across alternative tea cups at any nearby star. got you? well, it is that we are not efficiently managing ways, and there are raw materials available for producing sustainable and eco friendly products. one of these biodegradable cups, or at least one step in the right direction. now as kaleon

komatt just pointed out, using draw materials which are sustainable is the need of the hour. remember, there is no planet b and it falls upon us to secure the future of those who come after us. i'll leave you with that and see you again next week. good bye. and thanks for watching with ah, ah, with
