explained, oh, colton, go. the history of anti semitism is a history of stigmatization and exclusion of religious and political power struggles. it's a history of slender of hatred and violence, or even 77 years after the holocaust hatred towards jews is still pervasive. oh, history that you semitism this week on d, w. o, o, o i i if you live in the countryside, you actually familiar with the smell of fresh air, the sight of a clear blue sky and the feel of wide open space. it's simply gorgeous.

and it may make you wonder why anyone would choose to move to a city, but the fact is, 3 quarters of the world's population now live in towns and cities. that is over 5000000000 people. and as these areas grow, so do the problems from traffic congestion to storing energy demands. what we need are urban visions, our topic to day on may to welcome. now did you know that one in 8 people not only live in a city, but in a mega city, sharing limited space with millions of other inhabitants? and now imagine those millions on their way to work. not sure if the term rush hour still applies. in order to ensure people can actually move from one part of a city to another, new mobility concepts and need it. and sooner rather than later mushrooming

mega cities are a global phenomenon. there are now 3 times as many urban areas with $10000000.00 plus residents as just a few decades ago. but as cities grow, so do bad problems. stretches inched cities or microcosms of society. we can observe all the opportunities and challenges in a very small space, sort of like under a looking glass of you into the brand glass. the income, the biggest conservation on the planet is greater tokyo population. 38000000, followed by jakarta with around 34000000 daily mon, by manila and shanghai are each home to more than 20000000 people. as are the biggest metropolis is in latin america, south palo, and mexico city. traffic is a major problem in mega cities. but they're in new ideas out there on how to tackle

it globally. hm. we're also used to cars that we can't imagine cities without them anymore. but if we were to experience that, we wouldn't want to go back to cars method an auto select form. this is how cities might look in future if different kinds of road uses were separated. one road is for fast moving electric vehicles, another for pedestrian, cyclist and scooters. with a 3rd, a promenade reserved for pedestrians only. welcome to woven city a project under development by japanese comic or toyota, a prototype city, and living laboratory for cutting edge technologies. here all vehicles will be self driving and run on electric power or hydrogen. the mini city itself will be powered by solar and geo products in a city with $5000000.00 residents and $3000000.00 cars that are idle, 90 percent of the time. you just need to do the mass and i didn't off gobber. and

so that we could probably reduce the number of cars by 80 percent young aunt ben gun with a smart sharing system. people could still enjoy the same level of mobility and send a mention of ice. meanwhile, at the other end of asia, in saudi arabia, there are plans for a new megalopolis, ne um, a linear city comprising for urban hubs. the pet project of the saudi crown prince is set to cost an estimated 500000000000 euros road and high speed rail. transportation are all electric and underground. nissan, nicknamed the line because it's meant to be 170 kilometers in length, is designed to be carbon neutral with a 5 g network driving all manner of applications. and as yet right now, it's a thinly populated and undeveloped area on here we want to create sustainable infrastructures and stimulate economic activity, which will in turn create new kinds of jobs and economic development in saudi

arabia. the country is seeking alternatives to its oil based economy. me om should also boost tourism and attract start up st. media production companies . the entire cities, energy requirements are to be supplied from renewable sources. here we have a huge amount of sunlight and ideal wind conditions. so our energy system will run exclusively on primary energy on this energy will and also be used for desalination is energy, but back us water is a big problem here. i was bring me on is an acronym for new future. the plan is to create a city for 1000000 people in just 10 years, but is that really feasible? is lava dallas combined them? if the 2 projects have something in the? well, it's still, they're not what was originally hoped for blueprints and reality,

a miles, a part of the project. assume a managerial perspective, which ignores the fact that cities are more than just infrastructure. what draws people to living there is not something you can plan just like that on the plan because woven city and me arm to visions of eco friendly, high tech cities where people can actually enjoy life. but will they actually get off the ground? well, all i know is that compared to cities like tokyo or mexico city, berlin is a village and it does have lots of parks and green spaces like tree light, boulevards. but the streets are getting busier. traffic is getting worse. it's not just cars, delivery bands and buses, and of course more and more people are riding bicycles. and there's often not enough room for everyone thinks must change. and that's why city planners are joining forces with start up to come up with new and sustainable concepts.

who owns the city streets of berlin are increasingly busy with cause cyclists, pedestrians all the sea color gets around by bike newton. i not so little newton loudon graham and i don't want to live in a noisy, polluted, concrete jungle with i. i want to live in a city where people, chad on the pavement, common don't have to shout at one another over the roar of portions whizzing past to puerto kn beautiful but oh, what form fix my berlin was set up a year ago for the city cycling community it allows he uses to see, for example, where there's a new cycle passed away when you one is plumbed. it already has over 1500 uses. the

idea is to put pressure on up and planning authorities. if a bite on klondike mash gonna save you authorities or planning a new bicycle boulevard, were new bike racks on the public and see whether they approved the plans in northern michigan. okay, back to so you can see what's possible, what the public sees as a priority and what it sees as less urgent. i forgot any where there's less demand . it had been got it off auto villains, population increases by about $20000.00 a year. according to forecasts. the city will be home to some 4000000 people by 2030. how can traffic be reduced? how can traffic flow be diabetic, to reduce congestion and pollution? these questions that a group of scientists are seeking to answer with the help of data collected by traffic, commerce, aluminum. if my imbedding as vice pianos, let's take a busy berlin street as an example at a street,

you'd think it would be quite dangerous. a cyclist to detect oregon, but besides, if you ha, we'd look at their trajectories. invoicing, see if they often need to overtake trucks and buses, say a and see if that could be quite high risk of terms of competency i ah, the findings could be used by urban planners to redesign busy crossroads for example. traffic patterns are constantly in flux. recent months have seen a 25 percent rise in cyclists on berlin streets. when the pandemic hit, the city created a number of pop up cycle parts. but the fix, my berlin team says there's still a lot of work to be done. and i to unsticking british merriment enough in chicago compared to other cities. so the mayor of the student government and aren't very invested in cycling policy medical em than at one in paris and london. it's a political priority, long, etc. water. and that's our character chefs,

healthcare cloud. perhaps not yet, but the vision reason, city lab a working hard to get berlin up to speed yet green smart with pop up a bicycle pass. it's going in the right direction or the future of mobility will still include cars. and while many consider e cars or electric cars, a sustainable alternative to gasoline and diesel power transportation, it's not that straight forward is a look at some of the issues. electric cars like me, are still quite a rare sight. there's only $17000000.00 of us worldwide. that's just a tiny fraction of the estimated $1400000000.00 cars and total. but our numbers are growing. e cars use raw materials, mind in south america, the democratic republic of congo and china. these include lithium, cobalt and rare earths needed in our batteries. admittedly extracting and

transporting these materials is an environmental nightmare, often carried out under, in humane conditions. but their reserves are abundant. studies show that world wide deposits of these materials could meet demand for years to come. one good thing about us e cars is that we don't emit greenhouse gases, although manufacturing us certainly does. all my components still have to be produced, but my power train only has $200.00 parts, as opposed to a combustion engines. 1400, where my electricity comes from is another huge issue, renewable sources or fossil fuels. the good news is that the share of green energy is growing, which definitely plays in my favor. as battery technology improves, the range of e cars is increasing. right now, it's rarely more than 500 kilometers and often weigh less. finding

a tracking station can also be an issue as to our batteries, 95 percent of them could be recycled in an environmentally friendly way, but it's still not economically viable. but i recommend you sit back and relax it, surely only a matter of time to day electric cars cost more than conventional models. but that gap is closing the day of climate friendly, affordable electric cars, maybe about to dawn. so whether electric gas or diesel far too often cause and ob, stuck in traffic jams. but why? because who health there are simply too many cars on the roads. but we can look to mother nature to find a perfect example of how to keep traffic running smoothly. and i'm talking about

ants. now when it comes to regulating traffic, they seem to have it figured out. there are no jumps on their motor ways. bad traffic, bad vibes and highways are also super busy, but clearly run a lot more smoothly. in the human world, congestion on the roads is a normal part of life. we even keep track of record breaking jams. when hurricane rita hit the southern united states in september 2005, 2 and a half 1000000 people fled houston or tried to the resulting tailback on interstate $45.00, heading inland towards dallas, reached a length of 160 kilometers for 48 hours in the run up to the 2014 world cup and brazil, the roads in and around sell. paolo would gridlocked,

340 kilometers of stationary traffic, almost equivalent to the distance from sao paolo, to rio, moscow, november 2012. the notorious russian winter power lies much of the biggest country on the planet. for 3 days and 3 nights, snowstorms blocked the highway between saint petersburg and the capital. but how do traffic jams actually come about it? the main reason is that you do not have enough capacity. um, of course there are other reasons um, but these reasons, reasons are not that they do not happen that often. um, dumb people sometimes make driving mistakes. of course, um for instance they, they do not pay enough attention and then they have to break heart relax lexitas and silly weather conditions. but no. so then 60 percent 70 percent depends on the reach weight against you to agree with

the same thing with the same needs me again, but the world runs differently when i met with the principal is one for all and all for one not hardly applies to motorists on the road, everyone's thinking, what's the quickest way of getting to my destination? individuals focus on themselves and don't care about the others. most of the drivers have a lot to learn from ants. with lifetime i knew about the old, far faithfulness. i was a driver and wrote her name, quote, written it listing, and it is a thing which hinders the whole system to be effective. so

this would be a difference in the bed. the good is both maxima, that is, if you yes it the user optimum and the system optimum and nominated are the ones who have for him. so the best situation so that it is the user optimal, but his name for the system displays so and cooperate and have a common goal. humans on the road do 2 in a way they each want to get from age should be, but the lack of cooperation results and countless people wasting vast amounts of time in traffic jams. how much time precisely, telemetry experts have the figures take. for example, germany's biggest city think palm has made this kind of from statistics and they, they have a number of days, how much more time have you invest in on your daily commute and from pearl in this number, it's about 30 percent in other cities. it's much,

much worse. 3rd spot goes to bogota. residence of the colombian capital spend an average of 230 hours a year going nowhere fast. that's almost 10 full days. the frustration can sometimes boil over ah, number 2, bengal in 2019 drivers in the indian mega city spent an average of 243 hours stuck in traffic. ah, but when it comes to road waiting congestion look no further than maneuver. researchers worked out that in 2019 road users in the capital of the philippines last 257 hours of their lives to the daily commute to many self absorb drivers with big egos crammed into narrow spaces. anti waste by contrast are always busy,

but never congested. how did they manage that? can communicate by a sense, they have plans to produce them. various pheromones convey information such as danger, food all this way. i think it's long for that community that the system up to them. they want to have a working flow which is not stopped by individuals. so we can learn from the and, but i don't think that one can teach the people to be depend on a communal efforts and adapt as conditions change. humans communicate not so much with each other as against each other. and while costing us precious time that comes at a financial cost as well, if it didn't thank you the made so we have the highway and you say you have

a 4 kilometer jen to name for 3 hours. then you can drive only 10 instead of 80, then you can calculate what is the last time on the guy that end to end up being 510-0000 euro one check. and i calculated germany, for example, if you come up with 862100 1000000 euro. ready for year english, 80000000000 euro we lost just by standing still. and jeff, so you don't only lose time. ah, so what's left to the lessons can we learn from an existence then we can copy it and. ready this is the hope that then at

the end we will have a working traffic system which has a much larger capacity as we have today. oh, insights from ounce might soon be translated into better traffic routing and better attitudes. it's ultimately up to us. we need less ego and more consideration for others. it's better to cruise at a moderate speed, for example, than speed and slam on the breaks. perhaps then we'll be able to save ourselves a lot more time and money, and avoid seems like this. mm. and how do we get one h a into a city parks help without a doubt. but to what about those places? we actually spend most of our time in buildings from offices to homes. shouldn't they? to be more equal, friendly and healthy? now our ancestors lift in what's, perhaps it's time for this material to experience

a renaissance. oh, my new stance we put with deal in a forest lake is that i have nothing to do with the story. the story is about construction size, concrete buildings and the hopes and dreams of people living in concrete buildings . ah, maybe it's forest full of deer, lay dream on that there is a connection. after all that might explain why would is a fashionable construction material. it's those almost 20 percent of new builds in germany are made of wood either they're in the north where we're just about anybody who enters a home made of wood is almost always overwhelmed by its quality and atmosphere level. when's in if you're going to a newly built wooden house, you'll feel wonderful from the very 1st moment thanks to the structural design and

the very special atmosphere or one atmosphere. thomas vaskins company is developing what is said to be the tallest wooden apartment building in germany. 29 stories 98 meters high. it's called, well whoa. and is to grow up in berlin? langley, not the cities decided that entire district should be built of wood with new school buildings made of timber. and there is some justification for that. we have to aim to be climate neutral and our cities trees have bound c o 2 for centuries. and when that timber is used for building it remains bound. well, that's the key difference between wood and concrete and arched off baton. and, and concrete is getting a lot of bad press nowadays. a key ingredient is cement and according to the u. n's intergovernmental panel on climate change. the cement industry accounted for 3 times more, c, o,

2 emissions than commerce. so abby ation in 2019 another un reports as construction and building usage of the source of 38 percent of global c. o. 2 emissions concrete is the default construction material, at least for large scale projects. an entire new concrete corta is going up in a district of berlin. only one building currently under construction will be mostly made of wood. only its foundations and staircases will be made of concrete architect far each arabi has been working with wood for well over a decade with indefinite if you would definitely pioneers. and as such, we've also suffered. we had to overcome many obstacles. met with a lot of resistance from the authorities. we are to assemble a team of experts and of course, convince our client's property owners to begin with. it was anything but easy. i and thought. biden, 48 in berlin as a recent project of his,

the 6 story cow up with about 40 apartments is almost entirely made of wood and a fine list for the 2021 german sustainability aboard for architecture liberal, to be honest, our practice didn't originally warm to would for ecological reasons. that was 2007 . i started thinking about would perhaps 2 years earlier for its aesthetic aspects of the front as i go through it, i just found it beautiful. oh, it was only later that i learned how eco friendly it is, and that it binds large amounts of c, o 2 is r as many other yarrow than not all forgotten the woo, how high rise is not just meant to be eco friendly, but also an exercise inclusivity and social cohesion. it won't be condos for the rich, but rather housing for people of all income levels. as is, yeah, it's about living in a neighborhood in a community. if you live in

a project like this, you have to have the right attitude to wood as well because it lives and moves and creeks. you have to be able to and want to deal with that when ah, but to build with timber, you have to cut down trees. how eco friendly is that? we certainly shouldn't just chopped down entire forest so they're gone forever. well, we need to use the resources we have in germany and central europe, and fell tree selectively. importing timber from further afield would be less sustainable. the switching construction him get started at the warehouse site in downtown berlin. but if all goes to plan, the wooden skyscrapers should be standing by 2020. ah! and i was the final edition from us city dwellers on this edition of made for me

and the team here in berlin. thanks for watching sir, said ah, ah ah ah, ah, ah, ah, with

ah, with a go africa. these are the new speedsters on the streets of uganda. cargo, the bikes from africa, a international cooperative have high goals, reduce the c o 2, and create new jobs. eco africa in 30 minutes on d w. o. a
