da tawfik. smog fills the air in delhi, sparking a publilihealth emergency. the air pollution is so bad that schools are shut and millions are given facemasks. elizabeth warren releases he plan to a fal medicare for but some opponents are ququing her math. and it has bn a century of change for women around the world. to mark a major milestone, national geographic has stcollected some of the mo iconic images. nada: for those watching on pbs and around the globe, welcome to "world news americ" a public health emergency has been declared in delhi due to soaring levels of air pollution. in response, all schls have been shut until tuesday and million facemasks haveeen handed out to students. the city's chief minister said

the area has been turned into a gas chamber as a result of the thick fog caused in part byg fires used to clear farmlandcln neighboring states. reporter: it is like a scene from aystopian science siction movie. for the third day in a row, resi nts in delhihi inhaling theean's worst toxic air. in some parts of the city, the levels of pm 2.5, the tiny particles that can penetratera deep into ou ilungs, are peaking at more than 500 micrograms per cubic meter. the world health organization recommends a maximum level of 25. i am in central delhi, just near the main business district, and the iconic india gate behind me. but as you can see, it is barely visible, with a thick blanket of smog arod it. it is daytime, but hardly any sunlight is ab to peolate

the thick layer of smog that shrouds the city the government says it is doing what it can. it has banned construction activities and plans to limit the number of veh'es on delhi'ads. but the main reason for the toxic air is the burng of crop stubble by farmers in neighboring states. espiteseems to be no from that. >> in november last year, i was not wearing a mask. it was so polluted last year also. and i got really bad lungs. my doctor suggested me to wear a mask every day' >> i didt realize how bad it would get. do we really want our kids to ow in such an environment? no one really cares. no one wants to improve the situation. reporter: several studies say the pollution in delhi is damaging people's health at an alarming rate and causing premature deaths. it really is a public health emergency.

laura: today nada: today elizabeth warren released her long-awaited pl for t how she would pay f proposal known as medicare for all. she says she can do it without raisg taxes on the middle class. instead, among other things, she would boost the wealth tax for the ultrarich that she has promoted on the campaign trail. an came under attack from doesdd up.aying that the math the polls show that warren's message has resonated with voters in iowa. she is leading a newly release o pocaucus-goers, while biden isalling, now and neck and neck with pete buttigieg. i spoke to the bbc's anthony why is elizabeth warren releasing this plan now? we have seen health tere domihe democratic primary. anthony: exactly, it has

dominated the conversation, particularly in the debates. in the last debate in ohio sherm was pressed by the moderators and other candidates to say whether she was going to raise taxes on the middle class or not. what she did is she promised she would release a plan. she did, and as you mentioned, she has these different spending components. but she felt like she had to get ahead of this going into the next debate. nada: let's get into the specifics of her proposal. it is $25.5 trillion, a large sum, over 10 oears, but not requiring a penny to be raised on the middle class. how is she going to pay for it? anthony: there were cost savings different places, but a big component, $9 illion, she is saying she is transferring the emiums that employers pay to health insurance cpanies and instead requiring that the companies pay the federal government by her logic, this money is already being spent on health care. it is not g to be spent in private insurance, it is goisp to bt in a government-run single insurance provider thatte will be fficient and

have better cost savings and tobetter ablontrol prices. ofhe course,you talk to critics about that, whether you say $9 trillion moved around, it is still a tax. it is raising tas on employers ich they think will get past sed onto workers eventually. nada: is this a politically risky move for her not just in the primary but in the general election? anthony: pple are sensitive in the united states to the health system and their doctors and health providers. any time you talk about disrupting that system, there are people who are very nervous about it, the idea of moving from the system they know -- they may not be crazy about, but at least it is something they ararfamiliar with -- to a government-managed syste s even chmething like medicare, w they have heard of before, that is risky. when you are talking about a $50 trillion plan over years, that is a lot of money.

it is a risky tack t, but if you listen to elizabeth warren, she says be bold, you have to paint in broad strokes, thats the only way you get things done. nada: the poll i mentioned showing warren leading in iowa's polls, biden in fourth place, is this a turning point? anthony: biden -- iowa is not his natural state. it is very, at least with democratic voters, far-left. bidedeis doing better with black voters. e same in new hampshire. it is something tocernnally, but himself with. if elizabeth warren knocked out wins in iowa and new hampshire, biden has his backckp against the wall. momentum means a lot in these early primaries, particularly when it is a crowded field. nada: anthony,hank you so much. anthony:y easure. laura: nada: in some breaking news from the campaign show, beto o'rourke announced she is pulling out of the race. he tweeted out the announcement

a short time ago. he was a texas congressman who concentrated on the issue of gun control. turning to politics in the u.k., boris hnson has rejected calls from nigel farage and donald trump to work with the brexit party. he said he would not enter into electoral pacts but he was grateful for advice. he said the u.s. president was wrong to believe that his trade deal would be difficult. he was speaking to our political ra kuenssberg. laura: are there any circumstances you might work with nigel farage? prime min. johnson: first of all, it is a great brexit, it is a proper brexit, it delivers what we wanted, what i wanted when i campaigned in 2016. tak back our mey, our borders, allows do all-singing, all-dancing free trade deals. difficulty with doing deals with any other party is any other party -- i'm afraid votg with

any other party simply risks putting jeremy corbyn into number 10.he laura: are no circumstances under which you would work with nigel farage? primmin. johnson: i'm very clear th voting for any other party than this conservativeba government ically tantamount to putting jeremy corbyn in. laura: you are a mutual friend to the president of the ununed -- your mutual friend, the president of the united states, says you should workith nigel farage. is he wrong? prime min. johnson: i'm always grateful for guys from wherever it comes. we have regulations, as you -- great relats you know, with the u.s. and many other countries. but i'm just telling you, laura -- laura: so he is wrong abou that? prime min. johnson: i'm telling you about thway to do this. ura: president trump has also said that your brexit deal means you cannot do a good daml with thicans. is he wrong about that as well? pre min. johnson: there is one thing is certainly no question of negotiating on nhs.

he is right about that. on the technicalities of the deal, anybody who looks at it can see that the u.k. has full control. one whole u.k., england, scotland, wales, northern ireland -- laura: so the president hasn't oked at it, because he said you can't do it, we can't make a trade deal with the u.k. he hasitisunderstood it? prime min. johnson: i don't wis to commentat he may or may not have -- what i'm telling you is what everybody can see from the terms of the deal we did. if we can get it over the line with his election in the mide of january, we will have it done. laura: why wou anybody believe you on that when you have broken your promise already tout we have been out of the eu yesterday? you failediln that. prime min. johnsoni bitterly regret that we have not come n the other hand they said we wouldn't get a deal at all. laura: your first speech in downing street you stood up andc

said thestops here. and now thisnd gone wrong now you took a deal away from parliament and now you are blaming them. prime min. johnsonecwith great re laura, i think that mps were never going to deliver that deal on that timetable. not just by october 31. it was clear they would not have done it by january 31. eir strategy was to keep rope-a-doping the government and pushing the deadline beyond january 31. it would have been totally miserable. laura: would you rule out expanding the use of the prate sector in the health service? oprime min. johnson: we are putting 34 billion pounds into the nhs. that is taxpayers' money. we are absolutely determined to continue tincrease taxpayers money -- laura: do you rule out expanding private -- prime min. johnson: rse there are dentists and optometrists and son who are providers to the nhs.

that ihow it works. but i believe passionately in an nhs free at the point of use for everybody in this country, and if you ask me is the nhs, of course it isn't. sura: do you worry that t gamble of going to the country now might backfire for you as it did for theresa may? prime min. johnson: honestly, laura, we just have no choe. parliament is determined -- this is a parliament that is remain with the overwhelmingd bulk of mps in parliament voted remain. love them, a lot of my friends, but that is what they are, they voted remain, and they will continue to be ck brexit. ths wa option for us. laura: prime minister, thank you very much. prime imn. johnson: thank you. laura: the bb nada: the bbc's laura kuenssberg speaking to boris johnson. thousands of people have been

the combination of a athletes looking for greater exemess pushing participation to new highs. a sports editor for "the new york times" will be running on sunday, but first she spoke with us about the boom. thanks for joining us. tens of thousands of people from different backgrounds, ages,il abilities,be competing in the new york city marathon. why do you think the marathon's appeal to people who are not elite runners? g >> whave seen marathonow tremendously over the past few years. there have been twoistinct really appeals to people, it is a very specific challengt that a of ordinary athletes can do if they want to. i say they want to because it does take a lot of training. for many people it can be months and months, it can be s. but if you put the time in, it is quite aacincredible complishment to achieve. doing a marathon is a really big thing, and love to come cheer. it is a great event to train for and participate in.

isda: one of the things that blows people awahat we are constantly seeing records that once seemed inconcvable being oken. it has chaed the notion ofs what hume capable of, hasn't it? >> absolutely.y.we a few weeks agad two world records broken. ige in vienna, part of a b production. a ton of different pacers. it was a really a marathon for one man and one purpose,n o break two hours, ws,ch was achieved, once thought of as something that was impossible. the very next day in chicago, the woman broke the world record by over a minute on a certified course. it w an incredible weekend for running and incredibleoment for running where records continue to fall. nada: and yet for many people,' one marathon 't enough, yourself included. people trying to take on more pathan one in a short time why do you think people are

trying to push themselves to the mit, seeing this as a challenge they want to go for? talya: i think it is one of those things where after you do e e, you say, ok, i have d marathon, what can i do next. for some people it is doing re races. some people say i want to try different events, a triathloor then tre are folks like myself who love the marhon even in those hard moments. you get to a place where you know your body and you know how you recover, you can figure out how to do more than one in a short time span. i did the chicago marathon three we doing new york a few day that being said, i would not recommend it for everyone. it is definitely all aboutur knowing ody and how you recover and taking care of yourself. nada: on that note, do you think social media has changed the cultur are there some people not preparing enough but just attracted to the marathon to show that they have had this accomplishment? talya: there are lots of people who sign up for a marathon and

exmaybe don't realiztly what they are getting into. so of those folks may get inspiration from social media and really want to post. others may just not totally know all the traini that goes into it. but getting to the start line is a victory in itself.tt getting to the start line healthy isy victory. joining us. you so much for rklya: thank you. nada: next year a ntury since women in the united states got the righto vote. national geographic is marking the occaon with a series of publications and productions to highlight the journey during that time. for instance, the magazine's enre november issue was written and edited b with images taken by female photographer here in wash igt i, a new exhibit has opened featuring 10h of the besographs from women from national geographic's library of 64 million imag. the bbc went to ke a look. >> i think when you see in these

pictures is an incredibly inspiring story of the growing empowermenof women. you start out with women in very traditional roles, or women seen only as beautil objects, or sometimes almost as props to show off products or situations. but as you move into the '70s and later, you start seeing the real lives of women all over the world, and those are the pictures i'm personally most interested in. i love these two images because they areide-by-side and they tell you so much about the global state of women. you have this picture from 1968, a woman in afghanist coletely covered. you have this picture from 2014, a very stylish woman celebrating the cultural life in lagos, nigeria. these picturesogether tell you a lot about the journey of women.ve

we decided to his exhibit now because we are on the cusp of the 100th anniv 1sary of won getting the vote in th united states in 1920. in addition, we are at a real moment of female empowment that is going on around the world, as women are protesting for and getting their rights. i lovehis picture from 2007. this woman embodies women as warriors, which is -- we allen know wre warriors, but now we see it from her in the tongan military practicing martial arts. this is a strong, powerfulnd woman,hat is a great message. this picture came out of a story we did a few years ago about the tech revolution in africa. i love the vibrancy and beauty of this unexpected ige of rural women in kenya learning about their brd-new computers. it is a positive picture of what is going on in the world.st

i hope that eople coming to this exhibit will just feel joeat the sheer beauty of s of these photos and also feel very reflective about what we we see women in dit times, in joyous times, in times everybody can relate to. i hope pi ple will learn a lot but ultimately come away feeling inspired and empowered. nada: no doubt a lot has been achieved in the last 100 years, but still a long way to go. remember, you can find more on all that day's news at our website. plus, to seehat we are working on at anytime, check us out on facebook. i am nada taadik. thanks for watchin announcer: funding for this presentation is made possible by... the freeman foundation; by judy and peter blum-kovler foundation, pursuing solutions for america's neglected needs;
