even as mining continues not far from his farm in the last 4 decades, this area around the i'm and i base and has already seen ground water levels drop by it on 50 percent of the incentives like no, i don't have exploded in the last few decades and in the process, environmental concentrations have taken a backseat to each nomic factors. we need to come up with some solution, read, ecology, and economy. maddie, i'd like to set that as possible. as i told you, that the brings lot of sense. but we need to study that which area i need to allow, maybe to the and not to allow. what are the season read when you can allow and what are the see then when you do not. so that equation is required and probably you may get the answer for human being and really get the answer for eva and just associating biodiversity. 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 in force, many of these woods remain wanting as india of appetite for signed rules for those like archives who live in the shadow of unchecked sand mining. the air force to stem its damage continue, but why all the mining all of this sense? that's because us cities are expanding on people who need houses to live in. houses need sands to be bins. would it be fair to expect someone to live in a padded room just because we'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 the 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 site sometimes find themselves shut down? or slow? do a trick? it's something site engineer, solution with up real hit. must deal with often how about at this time have or medical sounds is 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 agent that keeps this together. 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. so you 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. often the indian government's attempt at controlling san mining have only said the business underground and mining has continued unbridled environmental engineering and research a d. b. i need your, she says some of these materials can be upside good for a cheap and sustainable replacement to stand by ash majestic to be there as the best product in the kind of my fault or any type of bonding. but there is a foldable name. where do i have to find those which tends to fly up to the to me top level is collected over that i'm, that's my us can be used for manufacturing of this flash of this upside. can fly ash good sauce to problems for the city at the same time. monday produces

millions of tons of flash. since tell it about plants account for over 90 percent of mobilized by one needs. the goal is also used us if you're in many industries in the region. government regulations have in foss. moya was a flash and constructions as a bind practice coming across the world. but this has not made a seed has been in and densities hunger for natural event 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, whether or not to attend have for doing that, 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 a handmade and hitting them? but the answer to them by sand and fly ash,

problems might be on the horizon or possibly across the world near the deals. but in the doctor 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 lay. and when i've been in details in the subjects, i realize that there is really a problem on the send. and at that time i had also experience working with the flyers. and that was the idea came up. okay. we have a sense of flyers, which we haven't problems and the concrete and the st on the, the sharp edge. and that's how that and get get from flash. the st. he came to germany from india to pursue cutting edge research in green technologies. and

founded a startup with support from the european union innovation program. after years of research has been 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 as to do, we can do that in mind. he's a man, physically properties, color properties. and the most important thing to the inside. it'll means that compatibility of light force and stuff does that if all of these properties on for the 5th requirements or for the extent that then we can see that i would like for is visit the 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 up the lab process into

a full scale production like the light bars eventually becomes slabs of sustainable concrete such as these and they're constantly improving the efficiency of the process we want to use and you know, less and less amount of chemical additives. so today the, these 2 at the tuition where we can make 95 percent 97 percent off life force can be made from the base of sense. so that means our most negligible, like using natural 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 the we to satisfy india's evergreen appetite for send in construction with bob, a full sized mafias behind the illegal satin mining jackets 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 manuals. green, as far as the i can see, that trees are growing again here near the velocity will, in the articles coming not do is largely times to speak on. and in a few years ago, this line, the baton after the sign mafia plunder that route. lastly, i select in 1983. the for the screen department is dr. to camp and to see if god, the solutions thought is because of at the time domain object absorbed to stop defense dealing activities. next, it belongs to an increase the size of the small, dense, wooded areas and green spaces. people had gradually taken over the store. 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 bins, literally, tickets that were there when i wasn't at school, had disappeared out and i was deeply saddened to see this. i made up my mind to keep blunting things in my home town to improve it and help my society and neighbors. 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 the, i have all of this place, the higher value on purpose. i mean, then on money gold, what are the riches and overall by value preserving nature is investment in boston, get down to the next generation and here's my greatest the pennies within. i've heard of it chica and has now planted more than $7000.00 trees, including many food bedding. but i tease as it goes to young activists like c con partisan c o 2 to 3 days, and update your color, g and eco system that give it to me in the 80 s a long that allows you, well,

we have identified 70 different displace. these up, 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 with the is on and the file out a little slow need to do anything that when the by planting lot of trees and projecting b solution for the stadium. so you can test significantly improve this community and the lives of other people. the sri gone still has a way to go to reach his goal. aims to glands, a small part is in every village in the area to give something back to nature. we need more such people who are committed to the idea of preserving our environment. and we also need more ideas to build sustainability because we cannot, of course, start 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, of the
