i think it is still worth it if you spend 10 percent more or 15 percent more and after 5 years it base 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 are 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 the needs of the are right now. at the moment india has around 1400000 modern homes built with the 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 begun 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. with inspired by all instructors that history has to be studied because historically what people had built naturally it is known that they are the best structures and that what we do is we can temporize it. 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 toilets so all that were broken and used in the form of a pattern and since a lot of them were laid to reflect 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 in a below before you want a system that will lend green building 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 claim saying that does simply fire homes let us give more open areas let's reduce the build up area let's go in for more green measures let's go in plant more trees because they help you not taking care of pollution as well. is green building design the wave of the future in india architects like milan john but while hope so and are ready to play their past.

rethinking cities is a mammoth task with heaps of challenges how for example will be 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. so most of us rubbish is just a pain it looks bad smells bad and yet it has huge potential clever recycling we can make extremely useful products from it like in the netherlands. we are 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. says cities account for 70 percent of. the dutch capital amsterdam is aiming to create

a circular economy by 2050 that involves could tailing the use of new rule materials avoiding waste and reusing as much as possible 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 never got around to ferrets of all the plastic in the ocean actually traveled by reverse towards the ocean and quite some trash that you see on the street or this is there and up in this rivers and then of course the rivers flow it's worked to see you so it's one of the band 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 pumped out of poles 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 sectors 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 want riverside's that are clean they want to have terraces where you can fit on 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 may call cow mera which has many up locations as a clue opined an agent in the manufacturing and construction industries. but if you want to have a circular society that insurance 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 with bio gas relatively low failure education and we're producing discovery and i just don't know we can use this before i feel you i think your shirts show what we want to do in here and the promise of produce i show you

building material sort of shapes using ways far from shoots of. standard industrial plants 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 tons of us a year. in the slop research as a working on new biodegradable 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 comair and toilet paper can come to market but prospects look good. for infrastructure hardwoods that's believed to

bore by this material and also aluminum and now the mini is a huge market with aluminum has a very very high c o 2 footprint and a good thing of this material if you can beat it or mechanical properties and also to property if you build it anyway so then the price will be the challenge and i think the co-op coming 10 years we will try to replace aluminum body discovered near a composite material. recycling and up cycling organic waste and construction waste could be a money spent and would certainly be good for the environment. spend 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 for a city determined to be a pioneer. and

now we leave technology behind us and head out to the mexican countryside. to meet your family living much like the generations before them. hello my name is. that 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 in the senior is 15. that's miguel.

course not just fog this is pepper spray and tear gas and. very coughing provoking mixture of over there so police just at the park and i would say from what i otherwise have experience of in a very nicely manner saying listen everybody has to go curfew will be enforced you will get arrested you get sprayed or tear gas or pepper sprayed please go home and follow orders so that's the situation right now you know shot in the night is young here locally. who knows what's going to happen the next few hours you're going to monitor this but this is the situation right now a curfew enforced for the 1st time in the 1st night here in konoha wisconsin and all in response to the killing of the shooting i should say of jacob blake his family has been making some demands what have they been saying.

you know the family and their legal. legal team had a press conference earlier today in the afternoon and saying that they were actually shocked and dismayed by the amount and magnitude of destruction which 2 nights of rioting or on rest has left kenosha kenosha in a lot of buildings were torched here and looted a lot of cars said to a blaze this seems to be over now but of course the family didn't want this to happen the mother of jacob blake pleaded with protesters not through it tarnishes then with with looting or burning buildings down or setting cars on fire on the other hand the family wants the police actually communicate why is that the police wants the family to talk witnesses to talk to say what happened. last sunday when jacob blake was shot 7 times in his back wearing a t.

shirt and shorts and that's all just for the record. they want the police to tell them actually what they have an evidence to is that body came of tiriel is there any other witnesses to the excited police is not talking the district attorney wants 30 days of investigation and then wants to come up with a report that is not to the liking of the family they want to have answers re very quickly not in 30 days ok start on time and in wisconsin thank you. staying in the u.s. where the 2nd day of the republican party's national convention is coming to a close with a keynote speech by the line you have trouble at the white house or the 1st lady told of her personal story of how she came to be us she also cast her husband as the best hope for america's future saying she was working hard to tackle the pandemic. here's some of what you have to say my deepest sympathy

goes out to everyone who has lost a loved one and my prayers. or southie. i know many people. and some feel helpless. i want you to know you're not alone. my husband's administration will not stop fighting until there is an effective treatment for vaccine available to everyone. let's bring in michelle stockman michelle was a speech a success for millennia drop. from needed a comeback story tonight and i would say she got one you may remember remember her 2016 convention speech was considered a complete disaster because she basically lifted portions of former 1st lady michelle obama's speech from the 2008 convention democratic convention so tonight this was the 1st time within this republican convention that i really heard an

appeal and a recognition of the grieving that many americans are going through because of the penn demick because of the recession she really connected i believe emotionally and i think she did humanize her husband in a way saying that he cares that he's working hard that he will as she said fight the invisible enemy of covert 19 and you're not alone we will not stop fighting so again this was her story showing that you. is part of the story of america the land of the opera of opportunity which is the theme of the republican convention tonight . looking at the 2nd night of the convention is this doing the right it's in the right notes that will get donald trump reelected it's really interesting tonight because i'm seeing the republican party for train itself as a big tent party one where people can find a place maybe. it's interesting it seems not to be trying to appeal to donald trump

but to people who might be a little controversial with his brash style or the way he's gone on twitter and made some kind of dog whistle racist remarks. it's trying to say you have a place here this is a land of opportunity and though i may be unconventional i'm fighting for you we've seen a lot of unconventional things tonight we've seen secretary of state my pump aoe give a speech from to roost that's completely out of the ordinary we've seen a naturalization ceremony we've seen a presidential pardon things you wouldn't normally see in a convention but this is donald trump style he's doing what he wants to do and some people love him for it and some people can't stomach that but he's showing voters who he wants to be ok michele still thank you. all right let's now take a look at some other stories making news around the world. more than half
