ah franklin, oh, ready to be sugars paralyzed between your societies, computers and governments that go crazy for your data. let me explain how these technologies work. so that's how they can also watch it. now, the everywhere you go in, in the i, you will find a construction site like this and mountains offense. hello and welcome. i'm sorry, got the body annual watching equal india. and today i have

a question for you. how much sand doesn't magic while? well, the answer is one k g f, up less than 30, at least enough in india. and we are single construction booming and dan would extracting sand from while she was foster, then it can be replenished. but what does that mean for us? let's find out into these episodes of the, even the smallest among those know that you can do wonderful things with sun. but here's what the kids might not know. the sun begins in the mountains, changes in temperature from frosty to warm, eventually caused rocks to break off the cliff face. the roof has been swept away by mountain rivers. the water infection with all their stones on its way to the sea, turns it over several 1000 years. in defiance of sand is important for the building industry. you can find it in every house. every office block on every street after

air and water, sand is the most needed not to resort on airs. ready with anyone who looks at our vast desert some thinks there's more than enough to go around with the wrong. ready doesn't sound as unsuitable for construction. the surface, the beach green is too fine and smooth. meaning that the green's don't bind instead, sand is becoming an increasingly skips commodity. son to mafia have long minded, illegally, even from beaches. but the kids aren't aware of this yet. the only worry is that their next on the castle is pretty. that's the last autumn. last live in big high rises like these offered dream of living in a lovely house on the beach as close to the sea as possible. but what happens when one day the sea is engulfing the beach and the waves come knocking at your door?

well, this is the thing and carolines are not. you got another question is, how do we save our beaches and the ending cost line? i'm can they be saved now? but the body beach in canada. augusta data is quiet and pristine and it's a bad job ged, build a dream house. yeah. my dad didn't move on to the i got married 26 years ago, and we built this house after 40 or somebody might have been work as a handful, earning just these 500 a d, to build this house. but as he has died now, we used to be so happy in this house. and i can see at the see view, the dog bed, what do you get to location such as this might seem wants to get my doctor mad at in this house. i don't want this i know this dream came crashing down last you and for the gt; life has become somewhat of a nightmare. but the body be to

become the latest sunshine in the bathroom between c, i'm land the see with duck by fee us months when started to is road the beach then if no contract you've used or vice versa. so a lot of that we wouldn't get the because of that sounds lost still, the village administration evicted us from here. i had said i would not be because they would, i go in 2020 to see those and claim the public road chunks of the road that had been reinforced bags to projects from the sea were washed away all along. the banks live the skeletal remains of homes. that one's a button, the beach but the body is just one of several places along india as close to se rose and intensify. and it's happening fast here. in just 5 years, the sea has tipped away nearly 100 meters of land or the length of a football field. to understand why this was happening,

we must go back to the u as in the boston pendulum. it does not do a place where it all started. load report with 2 revised, meet the see the to reverse bringing signed and settlement the see bushes and back . and everything clogged up at the miles of the boat. the area becomes dangerous for around 2000 boats. the boss through every day me of the board kept saying, well, the common phenomenon, the 3 for boards are in fuel, but it was still nice because of the less than that. so to all come to this problem . the very core dice are made in 9. the 9 these, these break, what does, what a break true for the fishing community here. the essentially just by, as of rocks and bags that act like gates that block signed from the mouth of the port. the ensure the channel stays deep and almost free of sand. fisheries boomed,

but the geography of the coast changed to the wave main leaves of it to lead to long short gutters and the long short cutters means of the water in last move batler to be sure to. so this is going to literally just where the waves striking the show creates a current that moves along it in this region. the current and with its sign from the beach is moved from knox. this out so that when he will have an awful cut outs on the shoreline, which act as badly as for the moment i'll say to me, before it is the combination of $30000000.00, lots of data, coat cups, and dental and doors. this always thought that i could trust in the case of mangled report, the big one was like an outcrop. it stopped the flow of sand in just a matter of jo sign was accumulating above the break was creating new, wide beaches. in the benefit of fishermen of the port and those living north of the break watch i bought it was

a beam for the salt house is rose and farm lands were washed away, ascend and land began receding aso trying multiple solutions, but failed. in 2018. the government in boston, i'm vicious $100000000.00 project to project the beach is south of the break. what the cost was strengthened would see was this project of the show to some extent artificial leave. so construct a deep in the sea to break up waves and reduce its force reaching the show. but dialogue is that solutions like these, where the sea walls are, reeves only created new problems elsewhere. one single construct i said well in one place, the problem going to be shifted to be just interior either door stopped us out. so the, the what the, what used to be a cheap thing. the problem is, so instead of finding the problem, so that is what is happening in the case of construction, will save us like 3 quarters the see was and we skipped end up redirecting the

waves to us areas, but i'm not protected. and this is what is happening, knowing about the body, uninstall gigi's house. the effort to save the neighboring beat has comma the cost of this this, the origin problem is not going to go away. so many more new boats are being planned in india. this means more break watches and see was even without bullets but other activities do that will increase in motion. more damage being constructed, undergoes that reduce the flow of sediment to the sea. 24 percent of india as coastline on nearly 2300 kilometers is equal wouldn't. billions of dollars would be needed to protect these shows. more erosion means most evils, and mostly wells means the cycle continues. india con, keep affording, to shift the problem. what do you say is, what the technology, what the, you know, what the pay locked the and what kicking this nature see, i know that don't go above save on what thought of being lot of basic but

a lot of lake and i know i know growing casually now, odd bellow but, but it's kind of it. so they did it. do they gave in a different than a deal perfect an extent and the, the way nobody is that could be, but they base their settlement and the very top out of them is that goes up to a certain extent. so we may say a goal for the green law instead of the one i bought the body, it's an anxious wait until the next month. so it is a pretty get was more houses when go. more themes will be to date. everyone is scared of designing here. despite a lot of attempts, big and small, the search for an equitable solution must continue on, insatiable need for sand is forcing us to dig deep into the reverse. yamuna is a major source of watch out for the city of delhi,

and the river is slowly dying because of sun lightning. and it's not just the river that design an entire equal system around it is also being killed. and the people who live alone cited of the invisible both north india as noise that active is solid. i'm to han was murdered in broad daylight in the year 2013 a hearty, fine day. his son will never forget semester or even so that's around between 11151130. and 3. people drove their bikes down this lane. they were from a village. they stopped the bike here. my father was resting in his room. the short him down. got back on the bike and flooded the bison muggy. violet, i'm to hahn had been fighting the sand mining mafia annoyed guy who has been operating unchecked for years. something that hasn't changed much to this. the practice that i've heard the livelihoods and the delicate ecology internet on the i'm one of our guys to han has continued his father's fight in spite of the up in

nature of the back to here, local authorities or joy gone. just define or describe the connection between local authorities and mining contractors for school because it is ramping up. so it's a larger scale gate name, but instead of say, you're gonna be up to the basic level. the top authorities are involved in management, the orders that they operate when, when are you? yeah. they say i, when you decide to go to getting a job, the money was a big nic organization has only increased demand for they put it in signed used in all kinds of construction projects. some 50000000 tons of signed is extracted from leaks. they have a beds, cost lines, and dental as every year. this massive removal of sand cannot be replenished easily and takes thousands of years to recover. the sam, some of the bed is especially valuable in construction,

says dr. for you as could side assigned just add the human eye. biodiversity box this send benefee, it is uh me more english literacy does that send that very light? the ready light, the venue see signed up to see if they have they have the capacity to absorb motor here with it. so therefore the very mix with it's been it has to go to properties. so these are all the differences in size and shape events. um, but he was saying that more angler and therefore being perfect, even when license is that all seem to mind signed, the law does not allow mining with hey, we machines like excavators, nor does it allow for building impedances in that it was flow in 2020 a contracted was issued, a license to mine, signed not far from orchestral hans land. who would i be to human mining and sticky

place at the moment? if you count up, you can see it. the $7.00 to $8.00 x covered the machines that on it look. big trucks that you see on the bottom of the bank of the it has already enrolled it loss it, you cannot, i had a mix and match with the bank. so it could have been indented to the natural flow, but it, but it has to change these areas. when you, because of mining, what was that? as a media, you go down the way i do, but it is much more than just a body of water that flows through up clean. it creates plot planes, red lines, gas lines, and dr. bailey and forest, which together created heavy, they both zones for humans and animals. that like the presence of sand in this type, adrian's own, is essential for life to flush, to renew the cold sand from some bad, you'll believe it to be, but a bit. and therefore directions,

and when we've got to things, it becomes kind of pull over the period of time and send please very important role because it is not only purifying water, but it is home for many invertebrates, many, many inverter bids and these inventories. of course you and 40, but they are missing. and this thing for those thing size, many farmers like that, i'm going to draw hon, who practice subsistence farming on land near the i'm gonna have also being feeling the impact of sand mining. in spite of being so close to the river, the sword has become incapable of supporting crops like potatoes, gloves, and mangles, which used to grow easily some years earlier. i've years um i have also going some a z or some sort of up to about most of the day because of this does don't room and my glove a table fruit on just have that be seen or lose them on 2nd. there are only $22.00 foods on the 2 out in the name of the dire situation, drove them be too big, matters to quote you and as mining continues not far from his farm in the last 4

decades, this area around the i'm and i be seen has already seen ground water levels drop by it on 50 percent ovens and does like noise have exploded in the last few decades. and in the process, environmental considerations have taken a backseat. we can all make factors. we need to come up with some solution. read ecology and economy maddy and that is a that is possible as i told you, that the editor brings a lot of sense. but we need to study that the material i need to allow you to do and not to allow. what are the season read when you can allow and what are the see then when you do not allowing and so that the collision is required and probably you may get the answer for human being. and when you get the answer for eva, and use the associated by the divers, different course across india have fast orders over the years to dane in san mining

activities. the government who has set tools for sustainable signed mining practices. however, on the ground enforcement of these woods remain wanting as india of appetite for signed rules for those like our guys who live in the shadow of unchecked sun mining the air force to stem its damage. continue. but why all the mining all of this? and that's because the cities are expanding on people need houses to live in houses, need sands to be built. would it be fair to expect someone to live in a patch just because they've used up all the sand and what's left is either very expensive or you need it? probably not. then what's the solution? the solution is recycling existing building materials. i'm finding out alternate materials, like, upside consent. let's find out more about this. over the past 70 years, india's financial capital one buy has gone from just under

a 1000000 people. over 20000000. the city is always building to accommodate its ever growing population. but hemmed in by the seat on 3 sides, the city has only one, be left a girl, and that's up. so why do some construction sites sometimes find themselves shut down or slow dielectric, or it's something site engineer, solution with up real hit must deal with often a lot of design have well, a lot of course on this the main component and the concrete we build with a model concept, it's made of an aggregate assessment and some don't cool typing it up. so i'm just the binding agents that came to this together. and so i'm 11, i how model do model sounds we need isn't available in the region. so it's important from other states like good jerome the say the at the despite being by the see, the city is often felt of sand for housing. it's growing population. recent estimates big the demand for staying in urban india at 60000000 tons. but your primarily in

the construction industry some of the best sand for using construction is found under rivers. but this mining does long term damaged legal systems and local livelihoods. too. often the indian government's attempts at controlling san mining have only set the business under ground and mining has continued unbridled environmental engineering and research a d. b. i need your she says some of these materials can be upset. good for a cheap and sustainable replacement to send my ash logistically there as the best product in the kind of my fault or any type of bonding that is a foldable name. or do i have to find those which sense to fly up to the to me top level is selected over that i'm, that's my us can be used for manufacturing of this slide shows this upside can flash can solve the problems for the city at the same time one by produces millions

of tons of flash, since teller about plants account for over 90 percent of mobilized by one needs. gold is also used us fuel in many industries in the region. government regulations have been forced more. it was a fly ash and constructions as a bind practice coming across the world. but this has not made a seed has been in and densities honda for natural send in large construction projects where spent as the primary concern slash aggregates have not yet seen widespread adoption by those who work with the materials every day. as there was a nachos hand have to do and that's what we call not true. sound has qualities the to difficult to find in the alternatives language reading since it's my made the wrong way shortcomings the strengths we get from natural sound isn't possible from them. i made some opponent, do they go home? i hadn't written anything,

but the answer to them by send and fly as problems might be on the horizon halfway across the world near this a deal. but in the dr. bus khan is overseeing a possible solution to the tough challenges currently faced by the construction industry. so when i was traveling in india, i came across a new state. the construction was hosted in monday. and when i'm in, in details in the subject, i realize that days are really probably the most sense. and at the time i had also experience working with the flyers. and that was the idea. i came with ok. we have a sense of flyers, which we haven't problems in the concrete, at the same time during the shortage. and that's how the executive from flash defense came to germany from india to pursue cutting edge research in green technologies. and founded

a startup with support from europe and union innovation program. after years of research, his dean made a break to and created the material they call life force. it lends as much strength to concrete as natural and they're both set. but it's made almost entirely from flash. so have to do, we can do that in mind. he's a man, physically properties, me printer properties and the most important thing to the inside of mindset compatibility of life, force and stuff to that. if all of these properties on for to fit the requirements or for the extend that then we can see that our life force is visible for the production of different building materials. as we do here, there process tons this into this this light bars can be used as a complete replacement for natural sent in everything from likely concrete to mason remote. the anal scaling of the lab process into

a full scale production light. the light bars eventually becomes slabs of sustainable concrete such as these and they're constantly improving the efficiency of the process you want to use and you know, less and less amount of chemical entities. so today the, these 2 at the tuition ready to be can make 95 percent 97 percent off life force can be made from the base itself. so that means all most negligible like you've been mentioned, resources use of cold is expected to see high in the coming decades in india. and so is the demand for bigger and better housing in expanding cities. this upside code division send me will be to be to satisfy india's evergreen appetite for sense in construction with bob, a full signed mafias behind the illegal sign mining jacket. standing up to them

could also mean that despite this, all young man is doing this on with the help of the community. he is also rebuilding plantations and creating modules green. as far as the i can see that trees are growing again here near the velocity will in the north of them and not do is largely tanks to streak on until a few years ago this land, the baton after the sand mafia plunder that route. lastly, i select in 1983 before the screen department started to campaign to see if god, the social thought is because at the time the main object absorbed to stop defense dealing activities. next it belongs to them and increase the size of the small, dense wooded areas and green spaces. people had gradually taken over the stores, she photos felt decrees and sun stealing activities, begin the as a young man, she comp left his own region and spent 10 years working in the film business in gen

night. when he did go on home, the entire area had changed. nearly all the deadlines, literally, tickets that were there when i wasn't at school, had disappeared down and i was deeply saddened to see this. i made up my mind to keep blunting things in my hometown to improve it and help my society and neighbours anything in places where the sand mafia had valleys, the land shriek on laundry trees under the stringent controls of the authorities. and initially mistrustful eyes of his neighbors, you're gonna go on there. i have all of this place, the higher value on purpose. i mean, then on money, gold, what are the riches and no problem i value presenting nature is investment in boston. get down to the next generation and here's my greatest the pennies within. i've heard of that chica and has now planted more than $7000.00 threes, including many food bedding that i tease as it goes to young activists like c con partisan c o. 2 to so they send the caller id and ecosystem that get it to be in

the 80 s a long that allows you, well, we have identified 70 different disparities all but with yet the people who live along very well benefit to mine. and when i have a lot of land here, 5 years ago, the area wasn't anybody see new to all the same. perfect do it is going to end up a lot. a lot of us literally do you do anything by doing the, by planting lot of threes and projecting b solution for the stadium. so you can test significantly improve this community and the lives of people, the tree guns fail has a way to go to reach his goal. aims to blonde, a small artist in every village in the area to give something back to me to we need more such people who are committed to the idea of resolving our environment . and we also need more ideas to build sustainability because we cannot disclose, stop building more houses, roads and bridges. but we also need our equal systems. in fact,

at all costs. uh would you like me to what did you like the most about today's episode and what would you like to see more of you can email us or write to me directly on my twitter. up until then have a great week. see you soon. take care of, gosh, the, the, the
