ah, i'm getting ahead. documentary series, founders valley, it's africa. meet the founders, empowering their continent through digital innovation, transforming work, health and living conditions in their country, and inspiring the world with their ideas. founders valley africa, watch. no deductible documentary with human interventions have transformed a word, but many hom, the environment demanding a change in our res. we've proved it's possible after global action,

the odds was only of is now recovery on e going be out today. we look at other damaging habits and ways to kick them. hello, welcome. i'm son, is that now cutting the use of chemicals in products like has pre and refrigerator has helped he the only but who be old 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. lance and why life? 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 janai is at its brightest bottom. i thought i remember only was at places like candy,

bazaar and wrangler. nathan street at night it feels like it's day time. it doesn't feel like it's night due to the use of bright artificial light lights, okay. the use of artificial lighting and chimney has gone far beyond what is needed to see and operate in the darkness. instead, it is become a source of light pollution, pantheon money, even on walker, but that worry moreland only like what to lucia. curious when the artificial light created by mankind, effects living being, he's pretty hard because they are being it other than my world. marcella, valet pollution of being a little silly areas, danella and then and i, we can witness light pollution and areas like that and i, airport zip code, monopoly and columbia do any of 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, clutter, and sky glue. if our linen relate bullish,

we'll use the portal scale to measure light pollution held on the boca 9 is the highest level 6 die turn. i records a level from 6 to 8 to the light pollution and then as i just met had been 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 upsurge. light pollution, according to researchers studying its growth usage of light is hitting unhealthy levels. they see i'm disrupting natural processes. yard order got home and they're not that he murmured. he sees the crow searching for its prey during the night. ha ha. similarly nobody sees a bat searching for it right during the day. their vehicle when you thought of medical release timings, i totally dependent on the like to present in the environment where what if,

if this is known as circadian rhythm, this cycle is affected by the light outside? yeah, molly opening it or they are too light. pollution is having a huge impact on plants and animals and can have unforeseen consequences in my pocket when he argued at lee up in california, hunger the army number already, turtles. while they're eggs, you now see sure and returned to the sea, but i got them available after a number of days. the turtles had shout direct themselves towards the sea and the active labor due to the bright light at the seashore. after the turtles get misled, they walked towards the road before they get killed, we call it up. when we see hundreds, i'd like to get in clear, follow up a note, they're going to play and then i'm a thought on the apartment, google you, they my, the medical team. it's the same with our flight. so probably we're not able to see any fire flies in the urban areas. you're out of a unit, but the reproduction process applies is completely dependent on darkness available

with the influence of these artificial lights doesn't allow miles to meet females either. and so they cannot, might mean, and that stops the reproduction process that a company entire species could become extinct. blue high light levels are not only having an impact on biodiversity, it can cause health issues such as eyesight problems, headaches and feelings of stressed. and humans. studies also suggested light pollution can in fact lead to certain kinds of cancer and people if the rate of pollution advances at an alarming rate higher than i'm a good while you're tired of it. and i'm 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 one pollution among people being available. there's an opinion that the right light looks good, allow them a little. we don't realize that we're both troubling others and putting ourselves in danger. what operating it over to one out of a regular 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 i format in, i mean we can see many footlights being used on the route from marina to royal koran. are these lights are important? i don't deny, elena. there's a flurry of activity over and also for the safety of women and crime prevention is very important can on, but why do we need lights so much? brightness swallow, can only relate 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, indiana marionette, a remote such regulations in india, laser, we need to set regulations and the monitoring system for it. we need to give awareness of like an allusion to the people. i see this as the 1st step to controlling the issue by taking action promptly could help human help and preserve the environment well up not the pollution. the plague,

the capital is notoriously 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 electric mobility. we had a look around to see how it's going needs and those mr. i was getting ready for his tech shipped of the deep this morning. he delivered milk across delhi this afternoon, its packages for a large delivery service. as always, he get that by electric vehicle or a leave for an electric vehicles and much better than patrol driven bacon and my general renters. mistress went around 1800 drivers employed by electric b logistics. why does the single the founder see the ad on a mission to electrify loss mind delivery services? that refers to those makers that delivered product from make bread and gadgets to

pretty much everything that can be purchased online. right to the doorstep. last minute ecosystem was one of the significant contributors for this air pollution crisis. and all the majority that we know you don't do any kind of data 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 talk to me at $21.00 i will window india 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. the non profit research group standard, recently conducted a survey on the last my emissions of the 6 largest global delivery company. it found that to the last mine delivery emissions in india equaled and estimated 500000 tons of carbon dioxide equivalent to the animals you do emissions of more

than 100000 federal passenger vehicles. ah, 80 percent of transport emissions is the actually emerson emissions in our breathing soon. so which is eyes of been the st. john's for their mission. it could be, you know, commercial transport, personal, private dock. but more sleep is commotion transport rate, which, which is what is affecting us mostly for fuel combustion. me quality daily, the vast of any major city in the world. the cities government has introduced campaigns such as switch to tackle the problems the state has. now, given companies in the cab, ford and e commerce, delivery sectors and deadline, they need to convert to electric by april 2030 and we have had very, very positive results on the uptake of electric,

regular decisions last year, 2020 to 10 percent of new decisions re elected 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 turned way electric. so it's a major shift that we are seeing in not just 6 firms. ingal is considered a formidable plan in the green or just the sector. the company handles almost half of the daily based 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 it's still a snug daily plan on our 30000 charging point in the coming years. currently just under 2500 opertitional ah, my interaction to bill, lot of tv lo 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 battery that designated swap points around to 50 point and this a d ah, they simply poured, we did that,

the battery from the waco from the electric waco, or discharge the battery comes into the station. he puts it into the station and hopefully by 3 comes out for the last 2 and a half months, minute off has been using some mobility slap points twice a day at the water come more metro station. daily earnings have gone up to about 1000 piece that's around 11 euros from when he used to guide his spectrum and to show why and how wide lot of ways are no issues like the need to use the cables or buyers for charging at i'm not normally just come here to the point and use the talk and we'll be judging by then we have a josh by 3 already and i think i can talk to between just 10 to 15 minute my god. in this one. 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 is fossil fuels, means ease cannot be completely off, andy. but there's still better for the environment than federal power breakers. and the daily authorities are optimistic, the ambitious electric brake policy launched in 2020 to ensure that a quarter of all new registrations by 2024 our electric. and meanwhile, e v drive was like some torch, missouri are leading the way on the city street. in more than half the world spoke to listen, relies on advice as a daily source of calories he, autumn, india. the staple can be on the menu up to 3 times the b. no growing rice may be good for our health. it surprisingly bad for the planet. our reporter wanted to know is that a better way to produce it? bryce is not light on the crops. 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, right farmers learned a common technique. they found the grain grew better in wet soil than dry one. and when they flooded fields, they found weeds dying to put rice survived. that's why even today, farmers keep field flooded for months at a time. and here's 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 i 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 hits 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 worse than a pork sausage or a block of cheese. but the sheer amount we eat means fixing right could save a ton of pollution the most obvious solution is to drain fields, so bacteria don't make more me thing. across. east asia, farmers have drained their paddies in the middle of the growing season to save water. and its waters growing 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 baranski 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 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, and some fun. and it saves water that's going increasingly sca but if intimate and flooding is so great, why on farmers 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 home 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 seas and

produce more nitrous oxide than fields that carry the wet or dry. that's because wetting and dry and create cracks in the soil that let him oxygen which reacts with nitrogen to form nitrous oxide. using less flatly that 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, said 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 the farm is a simple way to fix this, as by wetting and drying fields any sparingly, instead of flipping from bone dried to soaked. this means you get to same amount of rice but can still save one quarter of the water. another solution is to boost youth with other techniques, one approach and the system of rife, intensification that has spread around the world. it creates a better environment for growing rice by doing 4 things. found as take any the healthiest seedlings to plant in the bodies. they space and further apart,

so they don't fight over nutrients. they wet and dry fields and they churn 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. the growing rights clean is just one piece of the puzzle to hundreds of millions of tons of farm waste is another and away from it. 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 and packaging bite. these are many st. louis gale obligations, but a stroke. what you need to do is somehow use it to make either energy or some who i am a product that can be used on the farm research. this is an a beauty but nika, a scientist trying to work out what to do with the straw. daneen, and that is only 2 weeks. i beg window harvest restaurant and no next crowd 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 field with bacteria that break down the straw into mulch. farmers can mix it into the fields to improve the fertility of the soil, but it's great for crops. but breaking down the straw, take 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 heated at high temperature to turn it into a dry mass called bio child by a char, the porous carbon rich substance that can be mixed into top. so it has tiny holes

that trap water in fat, lighter in the soil lung, producing amount farms me to out. and it can even be chucked into power plants to replace the dirty of fuels like coal. it's promising i did. but setting up a buy a china mystery is tricky because the quality of rice drove very so 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 that i run, the reacted, i need to get the same quantity of bread out. but if research design out these technical kings, they could create a powerful alternative to binding rice stroke. for now though, breaking it down on the fall, maybe the more promising solution fixing rice it a no brainer. it keeps the plant 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 either is that unlike me to a dairy that new peak rice industry lobbying against change and holding back progress. busy challenge instead is to change the habits and traditions of famines around the world who can afford need a low, a yields no more extreme weather from one staple to another, less indispensable to french cuisine, butter studies. so it's carbon impact can be more than 3 and a half times higher than plant beast. equal bill is. so good. a wiegand crossel make the cut. let's get the one from batters can of legal croissant without butter. when over the french never go to the no butter. no, no, no, i don't want to live without butter. no worries them so that surprises me. paris, his 1st beacon pastry ship bernice lake conte takes on the croissant challenge.

just i bet he can cra, sounds can match, no more ones. but did she place her bet without considering french butter fans with 8 kilograms per capita per year? there the world champions and butter consumption security. that's part of our culture. we love butter like a must have in french cuisine, knob, gutters, french just like the bagget of both or by a butter with everything all made don't do with rice, with pasta, we put butter and everything, but the small bottles for the grill. the ingredients are the same as in the original and vanished lykins of beacon recipe. except instead of butter, she takes vegetable oil and so drink instead of cow's milk. the croissant is considered the supreme discipline among beacon baked goods. let ed eligibility to nicholas this is the taste of butter 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 del accordingly. hot it in as

a slice ish. when the dough is roll down, the star of the show is usually butter. bernice. let con 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. a rela, by the class like one to get even classes we use across song catalogs. i think you don't learn that in training, but it just is vast end of it. the class across on shape however is still done by hand and into the oven. they go, let's see whether the big inversion can convince the butter connoisseurs in paris. baron is la, can't opened her store in 2017. it was francis burst beacon pastry store at the time. she wants to appeal to as many people as possible.

doesn't get into again, people who are happy league and may still miss classes. well know, forget allergic children with an egg. allergy can discover pastries with us in the bathroom. sometimes people throw their arms around me because they haven't had pastries in so long all like they have. i'm and we have them with no dairy and no x, y last awful push. it 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 2 merrick instead of egg yolk for colour. to answer as i have asked me again, what attracts me to vague and baking is the challenge. i got a phone call when we opened 5 years ago, there was almost nothing else. 6 now there are innovative methods and new, vague and products. and the actual that challenge is to keep the recipes evolving to try manually fall fiscally. and it was that speaking of a challenge, the cross songs are ready butter versus no butter. because in

which one's better to me as good news or pleasant better concluded any more. 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'm 5050. well, i'm relatively happy with that. uh huh. so it's a draw. perhaps the french are 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 an old 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,
