i think it is still worth it if you spend 10 percent more or 15 percent more and after 5 years it pays for itself and then after that it runs virtually free of cost and you are giving back to the future generations you're giving back to the environment we're now coming into the concept of you know 00 buildings which are going to you know give back more than they consume i think that's the need of the are right now. at the moment india has around 1400000 modern homes built with a green concept which amounts to less than 5 percent of all residential properties the indian green building council hopes to take this number to 10 percent in the next 2 years and some states have become providing more incentives to green certified construction. however these figures do not

include the countless houses built by hand in rural india traditional dwellings that are often green in their own right. the with inspired by an old structures that history has to be studied because historically what people have built naturally it is known that they are the best structures and that what we do is very contemporary. but while renovated his own house in 2000 he was inspired by the traditional methods of environmentally friendly construction. i used all the broken barriers that came out from the toilet so all that were broken and used in the form of a back to and since a lot of them were laid killer days it reflects a lot of heaters very. more people can now afford the initial investment and more indians are growing aware of the impact of their choices on the

environment. they strongly feel that he has to start from and you have to adopt a 1st enabler before you want sustainable len being willing so i think the consciousness has come in and no make or not this will really pick up but i am sure of this. situation we have been receiving a lot of calls from claims saying that letters simply fire homes letters give more open areas let's reduce the built up area let's go in for more green measures let's going plant more trees because they help in you know taking care of pollution as well. is green building designed the way for the future in india architects like me learn john but while hope so and are ready to play their part.

rethinking cities is a mammoth task with heaps of challenges how for example will we keep the cities of the future. in 2016 the world's households produced 2000000000 tons of waste by 2050 estimates suggest i'll be 3400000000 tons of it 80 percent from city. to some most of us rubbish it's just a pain it looks bad smells bad and yet it has huge potential clever recycling we can make it stream really useful products from it like in the netherlands. we're using natural resources at a very fast pace some are finite others renewable but nature can't keep up with us . we also generate vast amounts of greenhouse. cities account for 70 percent of. the dutch capital amsterdam is aiming to create

a circular economy by 2050 that involves containing the use of new rule materials avoiding waste and reusing as much as possible that by slashing emissions. the city sanitation department fishes $42.00 tons of floating plastic trash out of the canals every year a lot more probably gets through. we now look around 2 thirds of all the plastic in the ocean actually traveled by a reverse to our sea ocean and quite some trash you see on the street or this is there and up in this rivers and then of course the rivers flow to work to see you so it's one of the kind of transport and magnus magnusson plastic pollution and that's why we would really like to stop it there a memory of elaine's is behind us start up the great bubble barrier and it's ineffective technology here's how it works a chub is laid across the bed of the waterway there is pumped out of holes along it the bubbles drive trash in the water to the surface towards the bank and into

a receptacle. tests have shown that on average 86 percent of trash in the water can be collected in this way. the garbage that ends up in the container is removed 3 times a week. for now only one bubble barrier has been installed in amsterdam it's a pilot project but the potential both in the city and world white is enormous. you have multiple factors that have interest in this for example you can imagine that companies that have a benefit of tourists coming by they want beaches that are clean they're one river sides that are claimed they want to have terraces very nicely and on the moment you install such such a system. and you can you can make it make sure looks nice to visit again

the firm has received financial support from the government it's also working on ways to recycle all the collected trash. cities also generate lots of waste water as unlikely as it might seem the water flushed down our toilets contains valuable resources that could be retrieved. scientists in the netherlands have developed a new waste water purification system to do just that. one of the end products is a gun they call cow mera which has many up locations as a clue or binding agent in the manufacturing and construction industries. but if you want to have a circular society to be sure it's that cycle all our waste streams and waste water is a very important way streams and nowadays what happens if you are in the end produced by a gas whether it's but by a gas relatively low shale you education and my producing discovery and i just don't know we can use this before i feel your applications show what we want to do in the hands of local produce i show you building material sort of using waste

water from the sorts of. standard industrial planes are made from oil which is not good for the environment. in the new process bacteria purify the waste water. comair is a side benefit a single plant can produce up to $800.00 tonnes of us a year. in this lab research as a working on new bio degradable materials. they mix cow marrow with recycled toilet paper and various combinations of peach pits and almond and pistachio shells. so far they've made great signs and developed architectural cleansing materials made out of 80 percent organic materials. more r. and d. is needed before this new composite based on cow merit and toilet paper can come to market but prospects look good for infrastructure hardwoods that's bitter bore by

this material and also aluminum and how the ministry huge markets with aluminum has a very very high c o 2 footprint and a good thing of this material if you can beat it's all mechanical properties and also your 2 property if you build it anyway so then the price will be the challenge and i think the co-op coming 30 years we will try to replace aluminum body discovered near accomplish that material. recycling and up cycling organic waste and construction waste could be a money spent and would certainly be good for the environment. saddam spent known as a great place for emissions for recycling for decades it's still a long way from achieving a circular economy. the plan is to make that happen by 2050 and ambitious goal 1st city determined to be a pioneer. and

now we leave technology behind us and head out to the mexican countryside. to meet a family living much like the generations before them. hello my name is a dealer. i spend most of my time here in the kitchen. it's where i like to be. this is my mother in law and this is my sister in law. i like it when they come visit. me my eldest daughter is 16 her name is maria guadalupe young. my other daughter is 15. that's me gal. you know and that's

this is d w news line from another setback to europe stole the vaccination campaign germany is holding astra zeneca corona virus vaccine for people under 60 the move follows new cases of blood also coming up. notes enough money the international community fails to reach its targets for helping millions of syrians suffering poverty and starvation. and the u.s. border under pressure from a growing influx from the south president joe biden's promise for

a more humane policy towards my friends is being put to the test. i'm here to mohamed thanks for joining us europe stolz coronavirus immunization program. am has suffered another setback germany is halting the use of the astra zeneca vaccine for the under sixty's people below that age can still decide to take the shot but only off to a medical consultation new concerns of unusual blood clots in a small number of patients has led to the suspension more bad news for germany's troubled vaccine rollout the government says it has made a tough but necessary decision. i believe that taking everything into

account this is the path we need to follow in order to provide confidence in the astra zeneca i can't explain all the uncertainty surrounding it though. earlier shot into a hospital decided as a precaution to hold vaccination off its stop members with astra zeneca a decision is expected in april overhype to proceed with those who have already received their 1st dose. citizens can rely on the fact that substances permitted in germany are meticulously monitored the results are transparent and openly discussed public opinion on this latest u. turn was divided at this berlin vaccination center only those aged over 60 can get their astra zeneca job everybody else is turned away. there are a lot of rumors and headlines in the news about it i wouldn't get vaccinated with

a. macuser trumbull this talk about people getting up thrombosis in the brain is very scary i'm going to wait until i can get by on tech or. i have no problem with it it's not a positive effect in england and they've all been vaccinated with astra zeneca. this latest blow to germany sluggish an occupation campaign follows new guidelines from the national vaccine commission you know. we learned from a regulatory authority is that younger women but also men are suffering from severe cerebral varying thrombosis. and have died from it. and the number exceeds what we would normally expect i thought age. we conclude that it has to be related to the vaccine therefore we have to act. without.

the bavarian state premier. favors taking a flexible approach. but some point with astra zeneca we're going to have to operate with a lot of freedom whoever wants to and whoever dares to should have the opportunity to take it almost 4000000 doses of astra zeneca will arrive in germany next month but another dent to public confidence in the vaccine means using them up could prove difficult. more in the us that speak to detail the political correspondent the only yvonne hummus stein any of the chance that is reassuring germans that they can still trust the government's vaccine program but what else did she have to say to try to instill confidence. well she sort of reaffirmed 1st and above all that vaccine and vaccinations are really the most effective tool we have against the grown a virus pandemic at the moment and she also said that she understands sort of the

frustration of people and the anxiety the questions that now arise with this u. turn on the astra zeneca vaccine but then she underlined quote unquote we will overcome this pandemic step by step and you can see that both her and the health minister he tried really hard to sort of like transport this sense of optimism and off hopefulness and it's very bleak picture pandemic picture here in germany whether or not that will convince the public that is another question but this is just the latest in a number of huge tens by the authorities here are gone the handling of the pandemic . yeah exactly i mean we just last week was the sort of last you turn where chance i'm going to have proposed an extended easter break lockdowns of sort of 5 days off and here in germany over easter and

then had to bat backtrack on that proposal and less than 36 hours later she even issued a public apology and so that's you as you mentioned that is only the latest sort of in this serious of a few turns and you can see that there is an erosion in trust that the public here in germany is not really doesn't really believe their government is handling the pandemic as well anymore 56 percent say they don't think the government can handle the pandemic very well anymore so that's i mean you have to remember last year that number and a lot of germans trust of the government to to really get them through this pandemic and that's aboard as a running now. well we also know that. facing resistance and also a lot of pressure now when it comes to her idea of wanting to push for a lock down for 2 weeks yeah exactly she is facing resistance even

from within her own party and some from some of the state premiers who are after sort of resisted the tempter restrictions they had previously agreed on and we're talking and specifically here about the so-called emergency brake that sees that is meant to see areas return to a hard lock down once they sort of cross a certain threshold of new infections and some of the state premiers have not implemented that emergency brake but instead of defending a course of action that sees a combination of repartee engine testing go hand in hand with the free very easy and off the restrictions and mechanised found very clear words to criticize those premiers and has even said if that did not shame she would have to think about overreach overriding state regulation so you can see there's a little bit of tension going on between the federal and the regional level here in

germany thank you that is the only vaughn thank you so much. health officials in canada have also put a pause on the astra zeneca vaccinations for people under $55.00 they were responding to the reports of blood clots in europe so far there are no cases reported in canada around 300000 doses have been given out and millions of doses of ashes that i have been deployed around the world. well eric fielding is an e.p.a. is an epidemiologist he says the benefits of the vaccine still outweigh the risks. this is very frustrating 1st of all kind of doesn't have direct you know their own they're relying on what's happening in germany but the same time i want to point out most of the astra zeneca that seems the country with the most use of the actually seneca recap is actually u.k. and u.k.

actually did not quite a find do the same pattern as as germany so you know why i'm not dismissing what the german epidemiologist found i'm curious why the u.k. do not find it because you have been using here much more and so until i see it in multiple countries especially the largest actually using country which is u.k. i'm not controlling campus but i understand the precautionary principle but the same time caution principle also says you know we know that the vaccine will save lives in the middle of a heavy heavy pandemic especially in continental europe and i think people are ignoring the fact that there is a well known major benefits versus an uncertain minor risk. a 2nd look at other stories making headlines around the world the u.s. is accusing china of withholding information about covered 1000 at the start of the crisis the world health organization says the virus may have pos from bats to

humans and was not leaked from my lab high well some countries have expressed concern about inspect is not having better access. and rubbish is piling up on the streets of me in mars main city young god activists launched a garbage strike supposed military rule protests started 2 months ago with the army removed the elected government and more than 500 people have been killed since security forces took power. a risky rescue as in colombia all such in for 11 workers trapped in the flooded gold mine the men have been struck stuck in an underground shaft for the last 5 days emergency teams are trying to pump out floodwater that officials say the mine was being operating illegally. an international conference trying to raise money for millions of syrians facing

extreme poverty has failed to meet its targets the virtual talk strays to 5 and a half 1000000000 euros that's 3000000000 euros short of its goal u.n. officials say the situation in syria is daya and is getting worse because of coverage 19. stranded in lebanon the u.n. is ensuring the 35 all of this syrian family. with the equivalent of 23 year olds per person per month the problem is the ongoing economic crisis means that's no longer enough for all of it is the bigger sugar and oil have become expensive. to continue help aid organizations need to generate more money this is one of the biggest struggles green minds that the national community reminds the older remind . actors the crisis is creating this to get these lift donors conference hosted by the e.u.

and the un wants trying to raise enough money to provide another year of aid for 13000000 syrian refugees they need for support. and of course proper funding is crucial today germany is therefore making its largest lurch in the last 4 years 1738000000 euros the donors want to offer money for emergency aid not reconstruction to avoid supporting the assad regime the regime offers no future to the city and people in makes no contribution to the stability on the region or less these changes it cannot be a partner to be a union the cement failed to reach its goal meaning they'll be fewer resources the people in the. u.s. president joe biden has promised a more humane policy when it comes to undocumented migrants crossing the us mexico

border but a growing influx is putting this to the test many children and families are placed in detention facilities and many are living in overcrowded conditions. a packed u.s. border facility and donna texas social distancing not an option for thousands of unaccompanied minors held at this processing center some lost their parents on the way to the mexican border others are brought here by smugglers u.s. officials say the influx of minors is steadily increasing. they know that we're releasing them they know that right now there's nothing stopping them we're not going to put them back to their country so they keep coming on board right now all these kids were started seeing younger and younger kids being brought over by their sponsors by relatives by grandparents more than 4000 people are being held and it was designed for just 250 every miner is given

a health check on arrival lies fever only people with symptoms are tested for covert 19. the biden administration declines to send unaccompanied minors back to their home countries as often happens under donald trump and they must be processed and housed within 3 days the average stay is twice as long. there's a little girl that i talked to a little while ago she said that she had lost her mom and that she doesn't have a father so she's coming into this country because her uncle is going to be the sponsor and i asked her what state are you going to what your part of destination she said i don't know all i know is that it's not was there. with more and more migrants crossing the border into the u.s. pressure on the biden administration is growing president biden wants far ranging reforms to america's immigration system but that could take years. to watch indeed all the news live from the lead up next hour covered 900 special
