this house of representatives has proved a bill, but could lead to a bad on the social media platform. take talk, the bill would force take talks, chinese earnest sell the top full will face having it from loops from us stalls. i'm reasonable home is back to watching. i'll see you soon. take care of the rules. we say they're about never giving up every weekend on d w. what i mean, i know i right just do it and i'm hoping dw newport costs, thanks. trace amount,

but there's no actually about move. joining us as we travel around your, facing the history of every day of that. and that's something right around the wells. and i need to talk to you back, just a subscriber id, listen to pop the fix to along to the right. the from delhi to east angle to los angeles. evolution is a big issue, especially in the world's biggest cities, between decrease or long function. it will increase, that's not that it's an increase of space. in addition, contributes to 7000000 does say, you see all these pink dumps, they show that it almost every major city in the world. the air is fonda t, as some of the world health organization consider safe. when we don't into the data though, we found some surprisingly good news. in many megacities, see here it's getting better. so we wanted, what are the city is doing right? that it can be placed through this

the, for this analysis we looked at one measure of evolution, that's everywhere. p m 2 point 5, pm, 2.5. be able to find 5 pm, 2.5, kids to concise pm stands for particulars matter. it makes show sort of particles and liquid drops instead of $2.00 microns for less, much smaller than a human here. this is only one possible type of information about people's lives. if he could meet from the w h o, use it as an indicator for evolution in general, just as employees. and that can come from very different sources. and because it needs to be, gets us into work. so there is really no place in the world that is the 3 of those are to get his mentors and it's big cities that are often particularly polluted. this problem has been well known for years to find out what if anything has changed . we took a closer look at this state domains from the switch company i q,

and we chose average levels of pm 2.5 for more than 7000 cities. over the past 5 years, we put it all into a big excel spreadsheet and check that against the list of the world's biggest cities. those has more than 10000000 people living in them. of those 25 cities, it seems like the air has gotten better in order even when levels are still high. what we've seen is that on average, about 5 percent improvement in air quality over the past few years. so we chase help cities that want to tackle the air condition problems. the causes are similar even when the proportions betty transportation emissions are often number one, not always but. and then also just generally electricity use people, cooking with solid fuels in their homes and some parts of the world heating was solid fuels. another major source of air pollution is from industrial sources and then also from weight. so here's what city is that doing to tackle these issues for many cities, changing how people move around just can make

a big difference here. so if you could me from the w h o again, there was a need to be a push to really have seen are very close, but also fewer legal reading from on working side team. and the, providing most of the big transportation was effectively the electric. they to take bank coke, for instance. the city is working on expanding its limited sky train and metro services. and in the meantime, electric alternatives pulled the traditional combustion engine trucks. let's keep looking around admission for you as well. denny is working on an extra fine 80 percent of his bus rates and even in coca town, sometimes called the diesel capital of the world of tentative psych visit electric scooter services starting up the next steps. so which i says can be introducing so called low emissions on cities that are restricting emissions and a certain part of their city votes to improve their quality, but also to improve quality of life. this might mean only allowing colleena cars to

into or no cars at all. and it might mean transforming speeds to make more room for pedestrians or by success. this is something that's resonating across all regions of the world right now. it's really exciting from times square in new york city, being competitive with this through an area to reducing traffic uncomfortable or being a horizontal to more by planes. and parents are putting cities everywhere, experimenting with a different kind of urban design. transport is not the only areas such as must tackle. there is extra time against air pollution also focuses on industry and measuring and reducing the dust from construction sites and having more industry shift to clean up fuels and more efficient techniques that converging traditional breakdowns to 6 atkins. this is something a lot of cities are doing like here in the heart process done. the method still uses cold, but much less of it and attracts more of the particulate matter inside the account, knowing it's emissions. one reason for dennis luxury, but yeah, the space might be that in 2018,

the city shut down the by the poor coal tall trend which wasn't comfortable for around 10 percent of the cities. particular air pollution are known. one area that progresses still snow is waste to their live. you solid waste management vinyl from 2016. this to not implemented every country has been advocating for clean air for more than 20 years. she found that the mother is active as group worry, a moms who campaign against evolution by petitioning the government and courts throughout india. she says, even in the right policies of that the government often doesn't follow through. we do not segregate the ways to source, and mostly it's all makes and that is what is making those huge landfills and the mixed race to insinuated in the middle of a city without organized waste collection funding is awesome. the only option for getting rid of unwanted materials causing toxic smoke full of handful particulate matter that can stretch for miles. so preventing waste as well as collecting and disposing of it better has to be part of any cities time to curve and pollution.

when policies are implemented thoroughly that can have a big impact. take placing, for instance, a decade ago, it consistently made headlines for its toxic smoke cover. but in the last few years, it has massively produced its pollution levels. and it's not just basing many of china's mega cities have improved or locked recently. this is the result of what the chinese government called a war on air pollution that focused on all of the causes we've already mentioned, but not least on energy and how people cook and heat the homes. the city of phasing impulse type limits on emissions from boy that's used in people's homes and subsidized anyone who wanted to upgrade that cold pad boiler to natural gas, which is to level so fuel, but produces much less particulate matter or to electricity which could be produced by renewables, studies show that 20 percent of the reduction invasions pollution just came from renovating these coal, fired going that's outside of china as well. countries around the world are investing in renewable energy, phasing of coal from the energy supply in favor of solar, wind,

and other countries like poland are also getting rid of the coal and wood fired stones and sol in south korea, which already swept cool. heat is for gas, back in the 1990s is now discussing the switch to more eco friendly heat funds for cooking stove fired with wood or kerosene activity on the option in many parts of the world, especially in rural areas, without access to electricity such as projects from pakistan to rhonda to the millions or introducing cleanest of models to those regions as well. whether and how 5 cities can implement change comes down to a few things. and the 1st total is bit of data. pick the hoard and pack of some irregular the top solice of the world's most polluted cities. according to the data, it looks like it has improved at least a little bit. it's hard to say without any actual changes happened. we haven't really seen any trends that would explain why the numbers are going down. so i

think it's just that the, the quality or data and prove is that beat omar? in 2016 he found as a pockets on eck, one of the initiative, which is the community initiative a life i ended up individuals, corporations, organizations, i've come together with low cost monitors and providing that data. a public lea uh on the internet on base that farms so that data is what is driving awareness impacts on. there are very few equities you want to set up by the government. this makes it hard to judge with that. things are actually getting better thanks to initiative. so there are no more than a dozen sensors in the for a long showing the current air pollution levels. michigan, honda for governments and citizens take northeast and the time monitoring systems have sprung up everywhere in the past periods. cities are increasing their ability to monitor their air quality, and this is something that is extremely important. a very positive trends from our perspective. then that's the question of money. changing was able to put

a huge amount of investment into the air quality problem. and that is the key question for a lot of other cities right now. do they have the money to invest, to make such a step change in their air quality? and last but not least, physical digital collaborations. so if you imagine air flowing together over parts of the world, that's what we call in the air shot and it doesn't respect political boundaries and found a place like deli, it's extremely important, but neighboring cities and jurisdictions work together on their common problems. cups of, of learning brings in 10 small to now that in the, including daily, every year after the harvest season. and the same problem happens, for example, in cairo or across indonesia, where smoke routes can reach so far. they affect the air and singapore, and parts of malaysia. so cities, regions, and countries will have to work together to change. because of what we have at the heart of the matter is the health of the people living in

a city. it doesn't really matter where the air pollution is coming from. it's extremely important that it's reduced. so evolution is still a huge issue. big cities all over the world are pretty far from what the w h l consider safe, which would be below 5 microphones per cubic meter of it, but it can get that time. so that's a tell people that they get this so disciplined us a fixed it's, it's taking me a decade, 0 for us. people like us to be fighting the field and the gods and coming with such a long re changes happen. so there's some changes in the v and even when really good air as far away, any change helps and the reduction air. air pollution is were found. any small reduction is good. what's more is that the things that clean up they are also good for combustion. climate change, which is likewise fueled by emissions from burning waste and fossil fuels. what would you like your city to do to pin up your yeah, let us know in the comments and subscribe to channels for movies like this every
