head in tech. as our documentary series founders valley, it's africa to meet the founders and pony they're continent through digital innovation. to transform work that health and living conditions in their country and inspiring the world with their ideas. on the belly, africa watch now on the w documentary with human interventions up front on the world. but many hom, the environment demanding a change in our res. we've proved it's possible after global action. the arts was

only up, is now recovering on eco india. today we look at other damaging habits and ways to kick them. hello, welcome. i'm son with that. now cutting the use of chemicals in products like has pre and refrigerator has helped here that was only but could be all reduce our reliance on one of the greatest inventions in history. the electric light bulb, artificial light, floods the night sky, creating problems for people, plants, and wildlife. we took a look in chennai when light pollution is having a big impact. ah ah, as darkness falls across india knight time is when the eastern city of chin i is at

its brightest eponymous. i remember when we was at places like candy bazaar and rang nathan street at night. it feels like it's daytime. it doesn't feel like it's night due to the use of bright artificial light lights. ok. the use of artificial lighting in general has gone far beyond what is needed to see and operate in the darkness. instead, it is become a source of light pollution, pear, tioga money than i want to protect, warning willingly like what to lucia cruise when the artificial elijah created by mankind affects living being he's 40. obviously they are being it other than my holy marcella. they lay pollution or being a little silly area, danella and then can i, we can witness light pollution and areas like the tennis court sip cause monopoly and co emberly in these areas will either have a greater population or more activity at the exponential growth of cities has made light levels of problem. there are 4 types of light, pollution, glare light,

trespass, clatter and sky glue. if our number light volition will use the voltage scale to measure light pollution held on the ball to the sky 9 is the highest level. 60, can i record the level from 6 to 8 to the light pollution when it is i just measured band wrong. it's only in the last 150 years. that earth has seen a light source beyond the natural light sources like the sun and the moon. but it's in the last decade that there's been a massive up surgeon, light pollution. according to researchers studying its growth, usage of light is hitting unhealthy levels. they say, i'm disrupting natural processes, yard order, gall hummingbird. i but nobody sees a crow searching for its prey during the night on. ha, similarly, nobody sees a bad searching for it right. during the day there really erica woochie. i thought i'd let her go for years. i mean,

i totally depend on the like to present in the environment there. what is it that is known as circadian rhythm? this cycle is affected by the light outside. yeah, a light pollution is having a huge impact on plants and animals and can have unforeseen consequences. and i'm a back up where are you in california under the army number already turtle. why they're eggs. you now see sure and returned to the sea, but i can. i'm available after a number of days. the turtles hatch out and direct themselves towards the sea. instinctively, but it was due to the bright light at the sea. sure. the turtles get misled. they walked towards the road 40 and they get killed in colorado, but we see hundreds of launch getting a note to kind of play and i couldn't. i'm a thought on the if i typical either a it's the same with a flight. so probably we're not able to see any fire flies in the urban areas. if you're allowed a unit becca. the reproduction process of live flies is completely dependent on

darkness availability. the influence of these artificial lights doesn't allow miles to meet females. and so that cannot, might mean, and that stops the reproduction process. a company entire species could become extinct. high light levels are not only having an impact on biodiversity, it can cause health issues such as eyesight problems, headaches and feelings of stress. in human studies also suggested light pollution can in fact lead to certain kinds of cancer in people if the rate of pollution advances at an alarming rate. hyphen m a is an awareness of my air pollution and even the sound pollution among the people for the water. but there's no understanding of like pollution among people helping it. there's an opinion that the right light looks good aladdin a little. we don't realize that we're both troubling others and putting ourselves in danger already, though it will not have

a record of the less. light is not just useful in darkness. it also holds cultural significance in cities like generally here using prominent lighting to celebrate festivals, events, and functions is important. so if all met, and i mean we can see many footlights being used on the read from marina to roy, a co, rum on these lights are important. i don't deny, elena does a flurry of actor missing her. and also for the safety of women and crime prevention is very important and but why do we need lights with so much bright swallow, economic delay that they are? these are common problems in many cities, regulations on commercial lighting, to tackle pollution exist in some countries. but more can be done, see environmentalists, india, london, marianna, to remove such regulations in india directly. so we need to set regulations and monitoring system for it. so we need to give awareness of like pollution to the people. i see this as the 1st step to controlling the issue, like taking action promptly could help human help and preserve the environment.

well up north, the pollution, the legs, the capital is lotoria, sw me in the air. belly is the worst in the country with stock since climbing to poisonous levels. winter after winter to tackle the problem, the city is banking on a shift to electric mobility. we had a look around to see how it's going. now than those mister, i was getting ready for his 2nd shift of the day. this morning. he delivered milk across delhi this afternoon, its packages for a large delivery service. as always, he gets that owned by electric power breaker or a lease. oh, i for an electric breakers much better than patrol driven baker and my general so retina. mr. i is one of around $1800.00 diverse employed by electric bees, logistics providers, ingle the founder, see the art on a mission to electrify,

smiled delivery service in reference to those vacant delivered products from make bread and gadget to pretty much everything that can be purchased online right to the doorstep. lashmar live ecosystem was one of the significant contributors for this air pollution crisis. and all the mental to do that. we know you don't do any kind of there is, you know, carbon emissions. they have no carbon dioxide emissions at all. demand for foster delivery dimes is growing and businesses are rising to the challenge with many aiming to deliver products. they do not 30 minute to one hour window. india quick commerce market is expected to go to a value of 5 and a half $1000000.00, or $5100000000.00 euros by 2025. but the trend is taking its toll on the environment. in non profit research group standard recently conducted a survey on the last my emissions on the 6th largest global delivery company. it found that to the last mind delivery emissions in india equaled and estimated

500000 tons of carbon dioxide equivalent to the and when you do emissions of more than 100000 federal passenger vehicles, ah, 80 percent of transport emissions is actually emerson's emissions in not believing, doing so, which is eyes of been the st. john's for their mission. it could be, you know, commercial transport, personal private but mostly to go motion transport rate which, which is what is affecting us mostly for, for some fuel combustion. me quality daily, the cost of any major city in the world. the cities government has introduced campaigns such as switch to tackle the problem. the state has now given companies in the cab, ford, an e commerce delivery sectors and deadline. they need to convert to electric by april 2030 we have had very,

very positive results on the uptake of electric regular decisions. last year, 2020 to 10 percent of new decisions re electric. and in december we touched a point of 16 percent. and in fact, the biggest change is coming in the commercial vehicle segment. for last my delivery of goods in 2020 to 60 percent of a because it is target lectric. so it's a major shift that we are seeing in not districts firms invoice considered a formidable plan in the green logistics sector. the company handles almost half of the deli base business of grocery giant, amazon fresh and gowns, almost all major e commerce companies as partners. but it's not all plain ceiling. i think the broader challenges that everybody feels right now is the lack of infrastructure in the market. so when you talk about judging of marriage,

when you talk about electrical connections, right? and dealing with this comes, then a still a snag daily plan to run out $30000.00 charging points in the coming years. cut into just under 2500. i'd appreciate my interaction bill, lot of tv. no drivers have been though the lack of charging access where they live drivers who have talked about difficulties in having charging points either installed in their homes or in basements or within their the places they live. even if it is not a gated community one company helping to build a workable energy infrastructure for ease is mobility. to solve the charging point problem, it offers up be as you go model, which allows drivers to swap batteries that designated swap points. around 250

points in this a d ah vase simply for we did that, the battery from the waco from the electric weaker. a discharge by 3 comes into the station. he puts it into the station and hopefully charged by 3 comes out for the last 2 and a half months, minute off has been using sun mobility slap points twice a d, y. com or metro station. daily earnings have gone up to about 1000 rupees. that's around 11 euros from when he used to died his spectral than lecture, while a wide gillian lot of ways are no issues like the need to use the cables or wires charging that you normally just come here to the point and use the talk and we'll be charging by then we have a job 3 already and i think they can charge to between just 10 to 15000000. lot of god thing that's the reason why they put in here. but there is still a long way to go. india as energy mix which includes $75.00,

which in fossil fuels means evie cannot be completely windy, but there's still better for the environment than federal power breakers. and the daily authorities are optimistic. the ambitious electric league policy launched in 2020 to ensure that a quarter of all new registrations by 2024 our electric and meanwhile, even dry was like some torch, missouri are leading the way on the city street. in more than half the world's population relies on rice and the daily source of calories. your india, the staple, can be on the menu up to 3 times a be. no growing rice may be good for our health. it's surprisingly bad for the planet. our reporter wanted to know is that a better way to produce it? bryce is not like other cropped. it was domesticated on 3 separate continents and

has fed hungry civilizations across asia, africa, and south america for thousands of years. across the world where i found land a common technique, they found the grain grew better in wet soils and dry one. and when they flooded fields, they found weeds died but rice survived. that's why even today, thomas keep field flooded for months at a time. and his what makes rights one of the dirtiest crops we grow. when back here in the soil break down dead plants, they usually release carbon dioxide. but in a flooded field where it can't get in, there's less oxygen to react with the carbon in the organic waste that encourages the growth of bacteria that make a gas called methane instead. methane doesn't last as long in the air c o 2, but it heat the planet 80 times more over 20 year period. what's more, the nitrogen in the fertilizer means putty spew out nitrous oxide,

which is $270.00 times more powerful than fear 2. if you look at emissions per kilogram, a bowl of rice itself isn't was then a pork sausage or a block of cheese. but the sheer amount we eat means fixing rice could save a ton of pollution. the most obvious solution is to drain feels. so bacteria don't make me thing across east asia. farmers have drained the paddies in the middle of the growing season to save walter at what has grown even scarcer. the trying a method of alternatively wetting and drying the puppies. so the rice still has enough water at its roots, but you're just reducing the amount of water that's sitting around and not reduces the amount of methane not being produced in the fields. this is mossey buranski, a scientist cleaning up rice and thailand. so in principle, it's a simple technology and it doesn't require any special machinery. you literally

put a perforated tube, or even a soda can into the ground which shows you the level of the water below the surface. and so you'd let the field drain naturally until it reaches that level, which is the bottom of the roots of the rice. and then that's when you flood the field. again. this simple trick is half methane emissions on some farm, and it saves walter. that's going increasingly sca but if intimate and flooding is so great, why on farm is going all right, this way. the 1st reason is changing habits and policies in bangladesh. a recent study found the ultimate wetting and drying has failed to take off because promise don't have an economic incentive to save water. they pay for the area of land, they are good, not the amount of water they use. so they see little benefit from using that. the 2nd problem is nitrogen fields where the water content varies over the season,

produce more nitrous oxide than fields that are the wet or dry. that's because wetting and dry and create cracks in the soil that let in oxygen which react with nitrogen to form nitrous oxide. using less let lay the can help avoid this, but trying to still trying to work out how to stop it entirely. but the problem is that you get less rise of the soil, gets to drive one review, found yields fell 5 percent in field that were repeatedly drained and flooded. it doesn't sound like a lot, but it can be life changing for farmers. a simple way to fix this, as by wetting and drying fields are despairingly, instead of flipping from bird dried to soaked. this means you get the same amount of rice but can still save one quarter of the water. another solution is to boost youth with other techniques. one approach to the system of rice, intensification that has spread around the world. it creates a better environment for growing rise by doing 4 things. found as take any the

healthiest seedlings to plant in the bodies. they space and further parts, they don't fight over nutrients. they wet and dry fields and the chun soil to kill wheat. oh, small hold of farmers have started using the technique which has gained support from governments in countries from india to indonesia. lot the growing right clearly is just one piece of the puzzle to hundreds of millions of tons of farm waste as another. and the weight vomit usually deal with it is toxic for both people and the planet. there are only a couple of useful things you can do with rice dro, like turning into animal feed or using it in packaging. but these are very small scale obligations, but i still, what you need to do is somehow use it to make either energy or some library product that can be used on the farm research. this is albert. he bought nika, a scientist trying to walk out what to do with the stroll daneen, and that is only 2 weeks. i'm big window, harvest of rice drop,

and the next group say good. so within 2 weeks after both collected transported and use it somehow, otherwise it 8 d grade that tight window mean the cheapest option for the farmers is to just burn it. stubble, dining of the practice that bloss pollutants into the air and chokes anti cities. the biggest problem here is an even climate change. it's a deadly gases that everybody breathe. one way to fix that is to spray the fields with bacteria that break down the straw into mulch. thomas can mix it into the field to improve the fertility of the soil, which is great for crops. the breaking down straw takes 3 full weeks until scientists can speed up the process. it'll eat into the planting time. another option is to take the straw out of the field and heat it at high temperature to turn it into a dry mass called buyer child by a char, the porous common rich substance that can be mixed into top. so it has tiny holes

that trap water and fat lighter in the soil lung, producing amount, vomit me to out. and it can even be chucked into power plants to replace dirty fuels like cold. it's a promising i do. but setting up a buyer, china history is tricky because the quality of rice drove varies very much that makes it hot for the earned of the reactor to actually sell by your child with consistent properties. when you're talking about any industrial process or any commercial buses, we need to ensure uniform quality, like every day they're day run that he acted, i need to get the same quality or better. but if research design out these technical things, they could create a powerful alternative to bonnem rice stroke. for now though, breaking it down on the fall, maybe the more promising solution fixing rice, it a no brainer. it keeps apart from heating, it saves dwindling water supplies. it cuts air pollution and it makes

a global food system more secure in the face of increasingly extreme weather will make the task easier is up on like me to a dairy. there's no big rice industry lobbying against change and holding back progress. busy the challenge instead is to change the habits and traditions of farmers around the world who can afford me the lower yields no more extreme weather from one staple to another. that's indispensable. french cuisine, butter, studies. so it's carbon impact can be more than 3 and a half times higher than plant beast equal balance. so could a wiegand crossel make the cut? let's get the one from batter's. can of legal croissant without butter, when over the french. never got it. no butter. no, no, no, i don't want to live without butter. no worries them. so that surprises me. perez, his 1st big pastry ship bevin,

he's like aunt takes on the croissant challenge. just i bet vague and croissants can match normal ones. but she plays her bet without considering french, but her fancy with 8 kilograms per capita per year. there the world champions and butter consumption. right? that's part of our culture. we love butter. don't like a must have in french cuisine. ab government, butters, french, just like the bag, get about to buy a butter with everything homemade. don't do with rise with pasta, we put butter and everything. but the small bottom of the grill, the ingredients are the same as in the original and val uneasily. cons. beacon recipe, except instead of butter, she takes vegetable oil and soi drink instead of cow's milk. the croissant is considered the supreme discipline among beacon bake goods. let that algy valid to request that the taste of batter is unique and difficult to replay and the vegetable oil makes the pastry dry out more quickly. okay,

so you have to adjust the moisture in the yeast dev accordingly, as it is ish. when the dough is rolled out, the star of the show is usually butter. about an east icon it takes. marjorie instead thinly rolled out, it's placed between the dough. the dough is folded over and over again and then rolled out. this is how puff pastry is made. over le bob, i'll request my gun to get even classes. we use a cossack as hell. i think we'll eat and learn that in training, but it just is vast end of it. the classic croissant shape, however, is still done by hand and into the oven. they go. let's see whether the beacon version can convince the butter connoisseurs in paris. baron is laquanta, opened her store in 2017. it was frances burst, big and pastry store at the time. she wants to appeal to as many people as possible

doesn't care. this is again, people who are happening league and may illness classes. one the font yet african children was an egg allergic, can discover pastries. with that and emily, beth, and sometimes people throw their arms around me because they haven't had pastries them so long. all like they've, i'm and we have them with no dairy and no eggs. my last off would you, this is also modified classics are on offer here. macaroni with moran made from chick the water instead of beaten egg whites or lemon tarts with tumour. it instead of egg yolk for colour. stay on that as long as can again, what attracts me to vague and baking is the challenge of fanco. when we open 5 years ago, there was almost nothing. yeah. now there are innovative methods and new vegan products and it's. 2 odd the actual, the challenge is to keep the recipes evolving to try manually fall festival in it was that speaking of a challenge,

the cross songs are ready butter verses no butter. because in which one's better to admit as good news brought liz's better concludes he anymore. it's less doughy and crispy, or i prefer this one. if this is better, what can we finish them? the result, 5 to 5. what does the pastry chef say? i said i have to 50. well, i'm relatively happy with that. uh huh. so it's a draw. perhaps the french or less butter crazy than they themselves believe. well, when intention meets action, even on deeply had beliefs and practices have the potential to change for the

better. if you have kicked him on habit to help the environment, tell us about it on eco india at b w dot com. i'll see you again next week. good bye. and thanks for watching. ah. with ah ah, with ah
