sharing people's most intimate movement. when you investigate south korea's by coming, the demi on al jazeera ah, taiwan warns china will be able to mount a full scale invasion by 2025 as tensions escalate over beijing's latest show of aerial force. ah, i'm rob matheson, this is autism, alive from doha, also coming up. i'm here today because i believe facebook's products harm children stoked division and we can our democracy. a whistleblower accuses facebook or putting prophets before safety boss. mark zuckerberg says the allegations are just

not true. ah, remembering lives last 2021 is not the deadliest year of the pandemic for the us. and venezuela reopens is border with colombia after nearly 3 years. ah, taiwan defense ministers wanting china will be capable of launching a full scale invasion of the island within 4 years. a record number of chinese military aircraft recently flew within ty, ones, so called air defense identification zone. the islands defense ministry says a $148.00 chinese warplanes had breached the area since friday. the flight stayed inside international airspace, but close enough to taiwan to require crop to identify themselves. beijing has recently ramped up pressure on taiwan, which it says is part of its tat. an article published earlier on tuesday,

i was president warned of catastrophic consequences for the white a region if the island was to fall to china. and taiwan is one of the issues in a deepening of strategic rivalry between beijing and washington. the u. s. president's national security advisors due to hold talks with china's top diplomat in switzerland on wedding state, joe biden. the says he's addressed the issue with his counterpart. she didn't ping, i spoke with you about how we agree we will buy agreement that we are. and we made it clear that i don't think we should be doing anything other than by the group or more than the story. let's bring in robin bright, who is live for us in hong kong. and ty wants defense minister issuing this warning very shortly after president biden's statement. just tell us more about this. well, that's why then the defense minister went on to say that the fact the relations now

the tensions with china are all the worse they have been. he says, for a 40 years, i think taiwan has been genuinely rattled by the scale of this incursion. china, as we know for many months now, has been sending air craft towards the island into the air defense identification zone. that's the air space running up to the island of taiwan. but it is the scale, the number of aircraft in the last 4 days that says worried taiwan. and in recent years, taiwan has been looking at the military build up in a china with some alarm. it was always the case that taiwan, thanks in large part to the supplies of f sixteens and so on from the united states . it had a military superiority when it came to the technological capabilities of its weaponry. that is still the case to some extent, but a china is quickly closing the gap and is there also is a recognition in taiwan or of china is increasing economic strength. that is now the juggernaut of asia and is using that economic power to further isolate taiwan.

so her taiwan is feeling increasingly under pressure. china is happy to exert that pressure, especially with the currency incumbents of the presidency. they're saying when in taiwan, who has taken unlike her predecessors a far more stand. osh offish approach to china was to keep china at arms length and china is happy to try to undermine her. but of course, there is a risk, a danger in this of that at back firing that that drives more people in taiwan to rally around their president, especially when they see the shows of force or from neighboring china. when we heard her years president joe biden talking earlier, saying that he'd spoken to president, she's in ping from china about the time i'm agreement under. they both agree to stick by it on. got the impression that as far as he was concerned, that was drawing a line under it. he done his bit as well. well. what does this actually mean in practical terms?

i think that probably there are moves afoot to try to de escalate, said they say people have be wanting to make a gesture and make a show, send a message and a people as both sides have certainly add done that in the past few days of joe biden has said they will stick by the tie when agreement, which probably means of hearing to the one china policy that you give a diplomatic recognition to vague jane. but at the same time, you still support the right of taiwan to defend itself. a, you carry on supplying a taiwan with a military hardware which always angers china. so that's always in the background of the relationship between taiwan, the united states and to and china. but this is a very important time. this comes right after china's national day on october, the 1st it was very keen to have this big show send a message to read a gauge taiwan as it regards the island for taiwan. they have a very important sir national day as well. coming up on the 10th of october,

that's just a few days time. so it is a time at which everybody wants to send messages and to do do gestures and show forth. but you do get the impression that as far she jim pink is concerned, they have certainly done that. and maybe he would probably want to see some sort of de escalation now as well. well, thanks very much, and he does drop more bright talking to us from hong kong. lucko harald as a senior political scientist at rand corporation, he thinks china's recent show of force is unlikely to escalate to a full invasion. at this point. the beijing is looking to put enormous pressure psychologically and operationally on taiwan in taiwan society as well as the one armed forces. at the same time, beijing is a signal to the rest of the world to try to listen from the rest of the world. some sort of understanding from china that their position is correct and that taiwan will not be allowed to do things like join the comprehensive and progressive

agreement on a transfer sort of partnership or deep. and it's on official ties with the united states, japan, australia, and european actors. however, i think what aging is doing is clearly millage rising the situation and pushing the rest of the world to recognize the nature of the chinese regime. that's aggressive, threat for peace and stability. of region aging clearly recognizes that the reforms that it wants to people's liberation army in 2015 still have a long way to go. 100 miles of open sea, the china would have to cross to bring forces over to taiwan to try to conquer free peoples. really be a very big challenge for china. even if it was only fighting the taiwan armed forces to say nothing of having to fight the united states and coming to i want assistance with possibly other countries even beyond that bringing assistance or economic pressure to bear. i think right now a china is looking to do is try to pressure taiwan to try to get some red lines down some markers in the sand. and to try to exploit

a campaign. psychological worker against the island leader, president, sighing one. facebook's boss is pushing back arthur, a whistleblower told, members of the u. s. congress that the social media giant is an urgent threat to its users. i'm a product manager. francis hogan says the company should be regulated at c, e o. mark zuckerberg says his research has been taken out of context in a post on facebook. he wrote that putting content only for profit was a logical because facebook makes money from ads. he said facebook's advertisers don't want their rides next to harmful content. and the tech companies don't set out to make people angry or depressed. that francis hawkins says site's owned by the company, han children, stoke divisions, and we can democracies chicago dances, followed her testimony on capitol hill. frances hogan presented a damning picture of facebook as a company knowingly disseminating false information that could inside anger and

hatred among uses negatively impact, teenager mental health and even stroke ethnic violence. but goal she says to increase the time uses spend on facebook and instagram, actively engaging with posts and then potentially be exposed to more advertising, which they would click on. this is how facebook makes its money. i saw facebook repeatedly encounter conflicts between its own profits and our safety is, will consistently resolve these conflicts in favor of its own prophets. the result has been more to vision, more harm, more lies, more threads, and more combat. in some cases, this disease is dangerous online talk has led to actual violence at himes and even kills evil. what makes huggins testimony so important is that she has the documentation to back up her claims, tens of thousands of internal pieces of paperwork that reveal facebook's knowledge of the consequences of its actions. allegedly in its pursuit of profit. how can call to more transparency and oversight over the algorithms facebook uses is like

the department of transportation, regulating cars. i only watching them dr. young highway. facebook is called hogans testimony, selective and misleading. but both republicans and democrats on the committee expressed skepticism of the company's truthfulness. they knew what they were doing . they knew where the violations were, and they know they are guilty. mark zuckerberg ought to be looking at himself in the mirror to day. and yet, rather than taking responsibility and showing leadership, mister jack berg is goin sailing. but there is an active debate underway about how much regulation to impose after all, who is going to decide what is inflammatory speech and what is simply information with a powerful don't want the rest of us to hear a starting point though, it does seem to be more transparency, transparency about the algorithms facebook is using to make us angry in the 1st

place and also more information about all the data facebook is harvesting about all of us. there was actual empirical data supporting all these downstream harms of the way the platform works. on those issues that are really at the integration of both, you know, the way data is used this, what we call surveillance, capitalism, where the user is tracked everywhere they go, and then that data's mind and used to target them and try to get them to the gauge how good has filed several complaints with the securities exchange commission alleging with our documentation, but facebook has misled its investors and congress in the past. and she's clear it is founded chairman and ceo mugs, zocker burke, who controls facebook's behavior. she habitants the al jazeera capitol hill. so fathers here, the death toll from grove 19 in the u. s. is higher than the total recorded. therefore, all of last year olds and 700000 people now died in the united states from illness is linked to corona virus. ah,

the washington national cathedral marks the fatalities by ringing its bell 700 times. more people have been recorded as dying from the disease in the us than in any other country, but tens of millions of americans still refused to get vaccinated. my county has more from washington, dc. in all, there are some 70000000 americans who have not been vaccinated. this despite the fact that the vaccination is free, that it is freely available in all parts of the nation. and clearly the period is that this 70000000000 if they're not vaccinated now. awesome, please not going to get vaccinated for whatever reason. and health officials pointing out that this is a new pandemic of the un vaccinated they. it is, according to the health experts are the ones who driving the surge. so this, of course, a major concern experts pointing as well to the possibility of new variance

emerging beyond the delta variant. given the fact that so many remain unvaccinated in total, about 55 percent of americans are unvaccinated. the only bright point of one can put it like that is that over the past month, the drop in hospital admissions has been some 25 percent of the number of recorded infections has also dropped for roughly the same figure. and since september, the 23rd of the death fatality rate has dropped by some 12 percent. so those are sign said health officials. i hope who showing that this particular search may be nearing an end. but they warn very, very strongly that there are possible variance on the way and that there is still no end in sight to the a damage being caused by the delta variant itself. and that people need to get vaccinated. still ahead on all da 0 desert replaces water,

in, it's coming in to was the mountain states but is not re pushing for the reason that and you can see was a flood warning out for alabama, probably georgia or jordan at some point that rain is going to be fairly persistent for a couple of days in the fall, thunderstorms says to be local, flash flooding, but it's a pretty sudden area at the moment. anyway, south of this, the seasonal rain is coming back towards nicaragua and honduras. so f f, you shower down in costa rica and panama not shares. it was in his band euro accumulate, it is still sherry at a mexico. the shout moved a bit further. south, south mexico city itself still potential to produce some flash flooding. but i think the place to watch is probably fair, the sas, guatemala, nicaragua, costa rica, ah, the stories that need to be told find a way i'm opening a window into another life. these are my babies, my students where i go,

where i feed them. it's just like we are in 2nd grade from personal endeavors in epic struggle to collect will sacrifice it in individual johnny witness joe case is been firing documentary the change the while on al jazeera lou. oh, what you know does it a reminder of our top story? is this our tie? one's defense minister says relations with china all the worst and more than 40 years. and the beijing will be capable of full scale invasion by 2025. a record number of chinese military planes recently flew inside

the 17.7 mile pipe wine has been displaced and it's been latterly displaced by a 105 feet. what they further located was a 13 inch split in that pipe on, on the side of the pipe, that a is a likely source of release of oil. venezuela's reopened its land border was columbia for the 1st time in almost 3 years. it was closed by president nicholas margotto in 2019, in the middle of a diplomatic crisis between the south american neighbours. tens of thousands of venezuelans had depended on the crossing the border for basic goods and services every day and a santa ramp. yeti reports from boca tar, just after nearly 3 years of being close to venezuelan authorities removed the shipping containers physically blocking the main bridge, connecting the country with columbia. in a nationally televised address some monday vice president delsey rodriguez said it

was time to turn the page. he am presenting thinking of our people and the brotherhood and co operation between the people of columbia and venezuela. president madeira has taken the decision to open the crossing for commerce in 2019 president, my daughter broke off diplomatic ties with columbia and sealed the border. after venezuelan opposition, members attempted to bring international humanitarian aid into the country. the aid was backed by the united states in bogota. my daughter saw da this part of a plot to overthrow him. but the border have been officially closed since 2015, bringing a hall to trade between the 2 countries. that amounted to $7000000000.00 us dollars a year. colombian president divan duke welcomed the news, but said the reopening would be gradual. columbia, a studies west columbia is also willing to begin an orderly process so that we can guarantee this border crossing. but i am going to be very clear that this is not

going to be done clumsily, and it is not going to be done. suddenly, tens of thousands of venezuelans crossing to columbia daily for goods and services . some 1800000 have re settled in columbia, fleeing the country's economic collapse most resorted to using illegal crossings, controlled by gangs and armed groups. when i do army be guarded, the reopening can also help reduce the role that armed groups had achieved at the border. both colombians like ill and rebels and paramilitaries, and also that as well and gangs who were profiting from people's needs to cross on tuesday, venezuelans were overjoyed, never. it's the best thing that has happened to us. we spent 2 years passing through a legal roads as we have so many needs that we can only fulfill in columbia. the decision will bring relief to people on both sides of the border by the will probably do little to help restore relations between the 2 countries. therein. mean

at odds. columbia does not recognize my daughter as the legitimate president of venezuela, and it continued to support efforts to push for regime change in the country. allison that i'm get the al jazeera over with her. what is envoys? the 1st official from europe to meet the taliban in kabul since is takeover of afghanistan. simon gas is the case special representative for of canister, and he's held talks for the taliban. the deputy prime minister molla bardari, a u. k. government spokesman says the disgust how brittany could help of ghana. stan addressed the humanitarian crisis and raised the treatment of minorities and women. afghanistan's industries are being squeezed because of banking restrictions and frozen assets. some multinational companies are trying to keep their employees and continue with production, but as long as they're somewhat binge avenge reports from kabul, staying afloat during an economic crunch. isn't easy. ah, it's 6 30 am and cobble in the morning shift is ready to begin the day. a multi

layered securities needed at the largest beverage production plant in afghanistan, career success story, which began its carpet and t trade more than a century ago. and now his presence in 46 countries, these carbonated drinks exported to the mid leaf infant nature. the one's family on firm is a multi $1000000000.00 enterprise. it's a household brand and it will understand and the workers take pride in maintaining the quality of their product. but since the taliban took over the revenues and production has been effected, it's mostly drawn by young. often professionals the out 2000 implies and afghanistan. many have chosen not to leave their country after foreign forces pulled out. i have started in afghanistan and i have to serve the nation and serve as my soil and my country. that's the

biggest reason i have a state being in afghanistan is not just about profit being in afghanistan is about to provide services for white products and to contribute to the economy of the country. for this company has been able to survive the tumult economy largely because its headquarters is not and have gone to sun even during the economic price . this factory continues to produce $72000.00 tons of energy, drink that hour. but this is an exception because the white economy of apply the sun is suffering and people cannot buy as much of that. what do you the construction industry, for example, is at a standstill. since contractors, agencies, and people in general have no real access to cash. most equipment has moved from yards. heidi select the and says used to send labor and equipment all over the country. now he's laid off 12 employees. they are all meshed kiln. nestor,

this is in this month. there isn't any work for us. the banks are closed and i had to pay salaries. and how can i manage with only $200.00 a week from the bank florida letter? my request of these lam, a camera is to stress on the banks to resume services that are about 200 to 300 construction companies here. they've all shut down and the staff had been sent home . but as the sunsets on the stationary construction equipment, evening shift has started work in another part of cobble workers here, sir taliban fighters have not come to the company or made any demands, although many are very of the economic crisis is here to improve security means they do not have to worry about being robbed or killed on their way home. they are hopeful their factory will continue its operation and in return attract investors to help revive the economy from the direct other. there are couple romanians presidents calling for consultations after the government was brought down by a vote of no confidence in parliament. the oppositions accused the government of

already. the sand is dangerously close to their homes. from above, the natural barriers looks like a fishing net cast over the sand and attempt to stop the unstoppable desert dunes have already buried homes. now it's headed for the nearby school. i'm from edible oak seen equaled up. but a cut sign of you see this sand dune wasn't there before it entered the school from the right. the ground was flat between those 2 blocks. this is a school for almost 400 students. that's an entire generation. a loss generation, a generation condemned to fleet, or be recruited more droughts here a rainfall. water has become scars, farmers and herders fight over it. in areas where the mountain state is largely absent arm groups including a kind of control access to water and arable land, giving it only to those willing to join their ranks. the combination of the arm conflicts and the effect of climate change is like

a death sentence for those population. when the whales are empty, i mean people are on, i have to flee in search of that water and there are places where people fight for water. it's a source of conflict between communities to day 300000 people have fled an area where there was once an abundance of water. the surface of it was once lake that had been is hot with an unknown gas in its killing. the remaining shrubs, forcing the last people to leave this vanishing away, sis in search of a more friendly climate. nicholas hawk al jazeera, the nobel prize in physics has been awarded to 3 scientists for discoveries in climate and complex physical systems. the nobel committee says chicago, mano be close hassle men. and ga perisi revealed grown breaking contributions to our understanding of complex physical systems, but includes making it easier to find patterns which helps us predict extreme

weather. i never imagined that this ah thing and i would begin to study higher that had gay, huge consequences and ah, i was doing it just because of my guy do. city last spring is a former chairman of the nobel committee for physics, and he explains how they pick the recipients of the prize when it should discovery, it has to have certain height is really be sort of a watershed yet. so you can see when of the floor and, and asking, and i think you know the status, you can say that if you go back to my novice work where he dump, you know, a complex system for, for, for the atmosphere of the low. he could by physical means, you know, you could compute that an increase in c o 2, the crease,

the temperature on earth and house. and then later on came, you know, maybe a much more fruit model of the climate. and so this is basic science. this is a discovery among, you know, this is, you know, and then of course, but what i should say is that, you know, usually in discoveries, if you use reductionism, you would down to score is one, yes. and then you can find patterns and then you can find formula, you can find it your find course or find work very superconductivity when you get but most phenomena in the world are complex there locations. and what these people have done is to have been able to select, you know, the right parameters within this very,

very complicated system by which you can predict and you can really measure, you can find the system. the systems are working here for the international space station is about to become cinema's most expensive. moving sets russian access julia pedestal and director clinton ship article arrived on board. they blasted off in a saw you spacecraft, shoot the 1st have a feature film in space. it's about a surgeon who has to save the life of an astronaut defying gravity. ah, this is obviously where these are the top stories taiwan is defense most as, as beijing will be capable of a full scale invasion by 2025 gallons worried after a record number of chinese military aircraft flu within its air defense identification zone. since friday, beijing sees the island as part of it.
