investors make big promises but years later reality looks very different from. drinking shortage i. was treated like gold. starts december force on d w. it's all around us we can't even see it but nothing on this planet would be enough to exist without being able to one of the essential characteristics that makes our look unique but the quality of far it is getting worse every day what can we do we could better not only for us but for the creatures we cohabit that's what we've

talked about how i welcome equal india i'm stunned that i'm. let's start by taking a look at bucca flies their presence in our surroundings indicates a hell the above meant much in the city like dent the perennial concretize dust butterflies are struggling to find a continuous green cup which is a basic requirement for them to provide a group of ecologists and citizen volunteers observed this phenomenon and are now striving to help them out. these small grass yellows are working hard the meal butterflies are looking for salt and minerals in the damp sun they need to ingest valuable nutrients to ready themselves for the meeting season. so. this is not some remote and pristine rural area but daily more than 100 species of butterfly

live in the city one of the very largest and most polluted in the world. so here medan is an ecologist of the conservation education center in delhi he's an expert on butterflies. the reason behind. us being lucky enough to see the number of species that we see in the ne is. is that we still have a lot of green area green spaces left in the early ones these. green spaces become such islands there can be no more movement for. we need guys beared any sort of wildlife. to go in and out of that protected space. in daily is continuing to grow in half as

a fashion. in years of greenery that connect the city's main butterfly sanctuaries be violent sanctuary in the south and delhi ridge in the not are at risk as more and more buildings go up. medan considers that a major risk to daly's butterflies. i don't the world butterflies are under threat more than 40 percent of all insect species are in danger off extinction as bawly need to butterflies are important for maintaining biodiversity for from a solo if you're trying to get to. either but then i find something on the cluster very a mere 3000 pardons then there's a man ducking me. veronique kapoor sort of has made a garden our latest habitat but we have been doing it right here across the river.

in order of corporate jugged. medan is heading to us good bet a batch of based land is being turned into a butterfly garden most of the land for the project belongs to the ministry polity some individuals and companies also make lots of ellaby. some of jan is an ecology student he contributes his knowledge and labor to the project by learning more about what butterflies need in order to try. this is akin to plug and all the plants that we have to supply and they are all our whole sponsor butterflies apart from the normal growth nothing or. there they act as whole sponsor of the butterflies like this one is for the common more. the major difference. of labrador the normal part will be that there will be

no formal design with the butterfly hybrid bad that you will be able to make out because we wanted to be overgrown we wanted to be growing violence for. the conservation education center daley has so far created more than 40 butterfly garden across daily with the help of hundreds of volunteers for as its manager helmet on shares his expertise and knowledge and encourages city doesn't to get involved and help look after the cities why life uncouple is one of the volunteers in just 2 weeks the 74 year old has cleaned out a trash full near johnson a city forest in the south of delhi and transformed it into a habitat for butterflies people were impressed but baffert award you mean. a bunch of bright blocks in this set around getting you getting

this is there does been sort of a ground where we throw all their money mark but now people have accepted that yes but nephrite bought a kaufman back and he is a. then are not a far colony. some years ago also hilma than launched a campaign to get people across daily to go out and count and identify butterflies near their homes every september. that has really boosted public awareness and enthusiasts to do something to have. once the. door is in place and not just being in place once we have substantial numbers 8200 but of labrador that's across the city we were definitely see large increases in the population especially for. the.

butterfly species there dispersing if there are $100.00 laid by a butterfly and another butterfly only whoville become arnold but of layers on their own the rest $98.00 will be eaten. and many more larvae are killed by pesticides some people consider the little creatures unwelcome guests in their garden think of all the glorious butterflies they might have because. now alongside butterflies every living being on the planet is polluted in the long term effects. to be devastating if pollution is a massive problem many cities in india last year in total a list of cities with the worst quality in the world and why where i'm the kid in

a 21 evolution was also a huge problem in london in the united kingdom but things seem to have changed now . everywhere. fog up the river where it flows among the green meadow fog and down the river where it rose defiled among cheers ships and the waterside pollution of a great and. he's worked one written about what a cotton or beijing. this is how charles dickens described it in london back when he read the novel greek house more than 150 years ago and he was of the only one struggling to breathe. now london still looks pretty great but it used to be even more polluted then

cities across india are today. you know busy. and so you see it. this matters because evolution is one of the biggest killers in the world every year we have w7w sprint to the gates who was based on who should i mean i think this gives you an idea of the terrible public health. we are here. satellite images show particular concentrations of 2019 greatest across asia and africa. europe meanwhile has gotten much safer so what can london's past teach asian cities today. the world health organization call their mission the silent killer every breath we take contains invisible particles the gases that to get them up to 3

years of our life these harm the lungs and meats diseases like asthma and lung cancer but those partly because the. particularly to look at their. peak at the everywhere this morning is one state will go into what would blow this street and then from there obviously they can affect. any. one of the biggest barriers that many governments consider pollution a necessary evil however many people get sick. and pollution rises when countries industrialize and cities across asia have developed like london did back during the industrial revolution. when workers burn coal to power engines they released particles that staying shut from shock tried to like dickens smoke lowering down from chimney pots make you know soft black drizzle with flakes of soft and it's as big as full grown snowflakes dickens's description stayed valid for decades to come

the amount of raw sewage at the time was so great that victorian london experienced the great stink a century later the pollution called the great smoke which officials at the time estimate killed 4000 people in a week now this made life as horrible as it sounds the folk was certain that it stopped trains short of shops and even helped the problem the dock and that's all before you factor in the cost to help london's died from lung to be like bronchitis in great numbers at the works at the peak of the pollution of the health damage alone is estimated to have cost up to 20 percent of british g.d.p. . the bad news is that deadly there today is pretty much a spot of london's weather centric like in london that cost lives. they've been about anything even city outreach now. and in the middle you know it was that you know you know like 26 now that it really all

about that is that i mean what would you say that. might assurance will mean that. that is. knowing the scale of the damage the parents in an impossible. get text about in winter because farmers in surrounding states burn crops and the cold air drops much that looks like but much of the urban india of pollution has come from burning more coal and driving more cars. when i grew up in ball in mumbai in the eighty's and ninety's having a car was an incredible incredibly luxury i bet if you samis had a car in the last 20 years let's look there lies a shinin globalization taking place in india. needs are. and these are not held to the same standards as scarse in the us

in europe. scientists say that quality 1st gets worse of countries industrialize and use more energy but then after a while the costs become too high to ignore and invest in solving the problem. that's how britain fixed it over the course of a century the government factories out of cities brought in a clean air act to find companies belch out poisons and replace coal cookers with got it built parks and public transport networks that reduce reliance on carbon and in doing so they showed critics of environmental regulations that saving lives also means saving money p.c. argument that if you want to go look at konami you need to destroy the environment by this story in the environment history might. not correct. but europe still has an. outdoor air pollution today still called the 400000 deaths in europe each year people in the poorest parts of state and often live close to factories in road pick with polluted. because europe has exported

a lot of its manufacturing to factories in asia has exported some of its evolution to. what kind of an indian takeaway from this. well thirty's are tightening fuel standards and in some cities placing power stations and restricting when you can drive. india is also looking next door to the progress made in china after president declared war on pollution beijing reduced its levels of fine particles by 35 percent in just 5 years from 2030 but in cities across india clearing 2 slowed to celebrate until the government tackled the source of the pollution residents are forced to live their lives around it. that's why director otto makes heap of filters to block toxic particles coming in from outside these there purify and start of wind. this isn't like in one of the this is something if you look like within a month then if you ask for the this is what you get this is the.

pollution what you put it in in the early this fridge that has been used for more than 3 months without solving the cause of the bad pollution filters like these just reduce the effects of the problem i am enough that i. know you know if i can manage it. well. yeah. you know and they make you think that's just a mother. but with so many successful examples to learn from indian cities now need to scale solutions up to bring the pollution down and if they really start fresh well they could do worse than going out and planting a tree. i think ingested street chockablock with gar stock scenes victuals trucks and to play a big part in causing air pollution in bangor it's not a very experienced spend what it all would in traffic to cover the distance of just

. a few decades in the city of come together to encourage more and more people to switch to bicycles when you can this be healthy and safe time and money. oh the world's most traffic congested city that was a designation given to bangalore to have the start of 2020 it's a dubious honor for india which is home to some of the world's biggest tech corporations. during rush hour commuters here spend an extra $243.00 are stuck in traffic into 1900 that's 10 days and 3 hours in traffic each year. so what's the best way to beat the congestion for ingenious kartik on the mountain bike but can he really be faster than his colleague who's driving a car. to. riyadh at the been among large

and we need to get to the don't move which is approximately. it from here so i get you there you. got to go on the mountain and good night evoked by the same company and good night if you will travel by car while can't think on the mountain will take us by. the. invention of. this heavy traffic. or a small stretch. if you're. cycling has been part of carthage on the mountains daily routine since his childhood as a seasoned writer he explored lean navigates the city's jampacked road using his tried and tested environmentalists friendly mode of transport.

taken with less than 9 minutes to cover the 2 kilometers the minimum and i get the full article. finally 6 minutes later his. police had a. very graphic look you know by. almost 15 minutes. got the langham out and is the clear winner but cycling in bangalore comes with strings attached the answered of course at 19 may have led to fewer vehicles on the streets but it is estimated that by 2022 the number of vehicles in the city will cross the 10000000 mark so even though it can be a quicker option riding a bicycle in bangalore can be dangerous as the city lacks cycling infrastructure such as bike leaves. the. for me my helmet and. my glove so there are 2 non-negotiable so the minute i mean.

when i get to these 2 come along with me. in 29 team got to climb the mountain became a bicycle ambassador for his company as part of a citywide initiative called cycle to work he wants to encourage his colleagues to also make the switch to using the bicycle as a long term solution to decongest this city. cycle to work was born out of a desire to target people who have the option to choose between various modes of transport for their work commute and ensuring that the off on a bicycle for that particular trip. the project was initiated by set them out and some good and a techie turn entrepreneur consulting on urban mobility and planning for smart cities.

for each trip comprises workplace location the route taken distance traveled and calculates the carbon emissions offset by the commute this creates a public leaderboard that is updated in real time. to do 2000 people in bangalore who are to do it or just heard on the cycle to work together they have clogged 600000 kilometers by riding their bicycles to work just within 2 years. traffic snarl ups are expected to reappear in the city forced lock down but the citizens of bangalore who are fighting hard to prove that bicycling could be a viable and eco friendly mode of transport for india's urban voc in classes. a simple choice whether to cycle to the supermarket or to work can have a huge impact on the air and also on how we connect with nature we live in an age where it's important to find that connection with the environment that. we can the
