[000:00:00;00] with ah, people move to the cities because that's where the jobs, the money and other opportunities are. but the planets metropolis is being stretched to that in more than half the world's population live in cities by 2015, this figure will rise to 2 thirds. that's more than 6000000000 people. over the next bill to you,

cities who gobble up natural habitat. the area covered by the triple people means more transport, more buildings, more waste, more pollution. with many of those made into cities of rural pool, they joined the 1600000000 people living without adequate shelter. it's vital to define sustainable ways to deal with this rapid motivation. i'm julie on the columbia, where plastic waste is for instructing new home for the, for in the vulnerable and i'm russell bearden, singapore, where one metropolis is striving for environmental sustainability in the face of rugged urbanized ation. bob gras. yes. is levy n over $300000000.00 tons of plastic produce each year with only a fraction of it being recycle. much of it ends up in lamp bills or polluting urban living environment. waterways in ocean in columbia,

tons of plastic waste is being diverted into the building blocks of a new environmental housing pollution. a columbia's capital city of bova is home to 8000000 people. and it is estimated that 650 tons of plastic is thrown away every single day. i have come to meet us for amanda, an architect and founder of a new enterprise for environmental change called from this class because he has brought me to an informal housing settlement on the outskirts of town to show me 1st hand the problems faced here and across latin america, we'll get we'll be lucky, geisha fall. okay? oregon ways, where is plastic or yahoo dot com. but those channels opinion was on yours. 75 percent of glass sticking packaging is single use. when you see all of this plastic on the ground, you see potential yes, a lot of potential weekend plans form all these plastic in order for oscars enterprise to succeed though, she's going to need

a lot of plastic wholesale, informal recycling has been a long standing trade in columbia, with 40000 trucks on the street to bogota, collecting conventional useful waste with the scrap metal and plastic bottles. so we're in a book bag. all right, now where the recycle is come to bring their plastics and other recyclable products and they weigh them here so that they can then be paid. ready for looking for poll . you know, he's the lead recycler. he's organized all of the was like was in this area over recent years. government support has allowed people like paulina the opportunity to upscale and legitimize the industry. creating recycling centers like this one all over the city. on video, the emotional she going with us is tall and again he's always cookies. i see lucy glenda. what alaska is a gravity does his whole rules as far as he planned. the ongoing challenge for

paulina and his team is getting the word out blowing to one another was on the other. gms almost at the other day. and who now will be gone. did begin boys knows what buckle mckinney a by the police. yeah. a way of knowing people and so they was like, oh, i didn't make it a month with me. same with if given was you? i don't me, ambien is a lovely middle that is like, i was like in the job she did on the thing that

a good as you on the almost somebody else gets almost like on the. ready plastic was awesome and as a new venture, which is making good use of this waste plastic i had to the company headquarters to meet up with. welcome to a perspective saying here, this is where we take all the plastic from paulina and made it that information. over the past few years, oscar and his team had been refining this ways to make durable building blocks different types of plastic or 1st ground separately. household, plastic waste, battery packaging and electrical ways such as old computers and t, v. 's. so you could feel like you've come straight from the, the battery like these haven't even been used. it's like a diet lender. what would happen to this packaging if you aren't recycling it, all the packaging for to consumer or assure is going to land. now we've got all the ingredients. now the chef will go to work. dan put it together. he,

he's the chair. oh, he is. oh sorry. okay, this is the shop. they won't tell us exactly the proportions credit. the speaker wrap the piece, the ground plastic are mixed together. he did and then compressed into brick shaped moulds. tell me a little bit about the temperature. what. how hot are the plastic? we just go to menu point depends of the amuse, depends on the plot. the green longer do all your 40 degrees. it is very important that the temperature is kept up melting point was not to burn the plastic and the least toxic gases. let's take this out. let's look at it. it looks like the manual. not as heavy, but in 30. i wonder what that was for that or that band. we are telephone numbers. we have another 51 number 4. so now that we

have all of these, rick, what kind of uses do you have for them? imagine would you made this same thing with this kind of work? and where are these going? rigs are going to cali. usi what we're going to do with recognized globally as the world capital. salsa dancing. the city of cali, 400 kilometers. west of bova is one of great social 56 percent of the land area occupied by slums housing, 40000 people a week and who in the neighborhood. and mister prolly, one of the city's most deprived area. oh yeah. oh phone. yes, i do. gotta read them ill from your leaders upstairs to catch up with oscar and his bricks. wow, my goodness,

the bricks. we just saw it in the factory there actually constructing into an house for someone who is here in the community. i think last time i thought you were involved with bar at the plan. we are moving. these things now are here and building. it's amazing. tell me a little bit about what stage you're at right now. we are in the kitchen. aha, where many meals will be cooked? i'm sure. yeah, this is the bathroom. mm hm. this house cost $5000.00 and has been micro financed by the community for elfaire mia, whose son lives in the apartment below? where me amok. ethan? yeah. not be a star. and we're not going to issue a new, a ha, see, get that back on 6 young because it's fussy boys. today we'll start seeing, oh no, you're so fussy, leap away. no. it's literally like lifesize lego oscars hope is that this project will generate interest in the community and encourage future collaboration. meet up if that was going through the in the

natasha into the law that he just has. so need to get plastic or to go out there. okay. looks like rock to them. a government with me, i'm all up is remaining crack yesterday about. i mean, i mean, you know, you did mention this. i just can't get over the holes for the electrical outlets in the plumbing wire, the cable down in a city. so pick it out. it's actually a room now at the kitchen. but he's telling me this is where the closet is gonna be here. i've got no luck. i with the television on top. if you can imagine at the all we've got left is the roof and some doors. so we're pretty close. how much plastic is in this house? this house we use is 5 pounds teen compact. thought is it plastic or where do i say it was on one of the minute continental. like what encompass

a little bit. okay. okay. i will let because will not report in just under 2 days the house is almost complete. the plan is that a family of 4 will be able to put together their own home in less than 5 days. time . look up as other carriers to our room to room isn't full. this is the woocommerce that is november. william was on me concept. this last because have already helped to house 42 families displaced by conflict in the town of guar pie recycling 120 tons of plastic in the process. tell me a little bit about the magnitude of impact that this project can have. if we use just to present their waste blasting the war, we can change life of 1000000 of people. we can finish their house in charge of fishing. look in america in just 10 years. that's an enormous number and a huge impact. we have to start, we have to step by step ah,

in what tentative, sustainable building materials are being developed globally. bamboo is being treated and use for construction in countries including ethiopia, indonesia, and here in the poll with many strains, 10 times stronger than steel and a rapid growth cycle 4 to 5 years. monday is one of most eco friendly building materials on the planet. in the middle east to engineering graduates and gaza have created an environmentally friendly break called glean take. this uses coal and wood ashes, a filler, instead of sand making use of waste that would otherwise be buried in the grounds. and in guatemala, one nonprofit is built a school using natural resources and rubbish that would normally pile and landfills . my zation is made the system out o tires capable of holding thousands of gallons of rainbow materials like these and not only paving the way for green urban sprawl. that redefining the space is green

habits. singapore is a low lying island in city states. 80 percent of its population live in high rise public housing resulting in one of the highest population densities in the world. challenges from rapid organization, sea level rise and increasingly chaotic climate is forcing plan as an architect and policy makers to respond to critical questions about how cities in the future will cope with growing demand. despite the growing pressure on space, singapore has been dubbed asia is greenest city. so i've come here to meet some of the people who are helping it earn that title. my 1st stop is the park royal hotel, which bowes, 15000 square meters of greenery and was completed in 2013 by award winning architect, which had hassle the earth. now in almost every way as being formed by human activity. though for us as architects,

we feel like it's something within our control to the jeff wise. that building projects can also play a much stronger role in the st. jude ship of the earth. when you look at like google earth or images from spice, cities are really desert. you know, you see a very bright white, shiny area surrounded by documentation. if people build buildings like this, you would no longer say that you would say the vegetation layer covering the city as well. to singapore, in government avoided talk, loyal it's coveted, platinum, green mark, the nation's highest environmental satilla cation is part of a white, a scheme to promote environmentally friendly buildings and investment into green city solutions. to understand more about why this city's the greenest in asia, i want to see what's happening at the grass roots heard about a non profit cross tennis, providing employment and supporting accruing into community. i've come to meet the funder like hot comment. i came here trying to get people to go back to basic,

and i thought as a result that we have a nice ation, globalization and digitization, that we come disconnect. so i was trying to create, using a space to connect back people and to bring better spirit the community. and it's very strange for a country like things well with us where so top down. and that's why my name is called ground up in a shaky ground. up initiative started in 2009 and secured a piece of land to provide environmental education for people of all ages and several workshops and seminars, building a community of environmentally negate citizens. i guess it for a moment, forgot that we were in the middle of a just knocking down your door. and in fact, we want to build on this land that to and i told the government to give me a chance to prove that. i think singapore needs a different cannot space 50 percent of the world population now leave in cities and

we 70 percent will leave out of 9300000000 or 9.5000000030 years time. what. what do you think will become where a full coming from? who wants to work on the land? who will clean the rubbish for you? all the same by malaysia in the ground up initiative gardens or meet choi finn and co volunteers have come along to get their hands there. why see yourself doing farming in a way i get the more connected with what we are actually doing every day because that whether it food we know exactly where they come from. and in singapore, i realize also people don't appreciate food because on maybe to the kids they have never seen this. how different is grown? maybe they thought it just from a supermarket. places like this is very good because it makes us go back to the basics. what keeps us surviving? what makes us try and if not really about having money, it's not really about having all the tech stuff, but really been able to,

to understand that you are just be what a part of this legal ecosystem thing. how things are grown, for example, it makes me start to ask a lot of other questions like how, where things come from. so if i use a paper, i start to think so way that from and if i troy away, is it going curve? we is committed to reducing her ways to almost 0. we go back to reflect to see if she's good and oh, this is the last place that you would expect to see a little permaculture garden going on in somebody's front room. i just started this journey barely a year ago. so a lot of things are to me, are experiments. you are here on your new experiment with all this. how do you, are you kind of creating a network? yes. because you can't be the only person to st paul into it. yeah, i on, when i saw that a group on facebook, it was sometimes frustrating because i seem to be the only person who keep posting . but now i think it's at least $5.00 to $3500.00. and it's quite

surprising. i think when we see individual taking just a small action to me is very encouraging because they start to take this ownership . mm. we and the journey to 0 waste community still have a long way to go. last year, singapore is 5500000 population. ditched over $7500000.00 tons of waste plus one half tons per person. but momentum is building and similar dress, which projects are sprouting up throughout the city. she met jason earlier at the end of the initiative and she's invited us to come across, turn and have a look at her own community. good. how are you? so this is your projects. yes. my neighbors will come and spend time here in the garden actually doing stuff. the ad directors, the i, c o lawyers, is there is a demand. me, is that so i never seen soybeans group before. i feel that

a lot of the open spaces and sing up bar should not be hot the couch or landscape. it should be foot speed. and how can mean, surely me sing up or maybe a, a sippy enough. what godaddy, why does it need to just be a small one? you know, that only serves a few people in the community. why not? the larger community, over 80 percent of the food consumed in singapore is imported. so the ministry of national development is investing heavily in boosting food production on the island . i've arranged to meet jack in an engineer turn food producer who's taking commercial skill urban farming to the next level. i can serve nervous uniform like this before. i was in the world 1st in the world for someone that's never heard of a vertical form. how would you describe something? a single boy landscape, so we don't have much our land thought of what he was for vash. give us single body

and we stay in the history. the fact is, is that because he look at why rest, they were out because i cannot go by the 30 candy. our system is using the hydraulics are using wiper, make it this power or the thing. so fun can go up and get a not fun. i cannot get a new trans in what so and the what the is a similar though. you get low tipping is a sim also give a thought, a plan and a what i will be get one. at least like i use it so far we not to change. oh, at that at all. so far you've not changed it at all wise. that's quite something given that this farms been operating for 3 years. these rotating shelves effectively increased the land surface area by a factor of 10. meaning this vertical farm can produce 2 tons of vegetables in a single day. meat pie pi king of the veggies. it's a beauty, is it all? it is a weed, as the 1st we'd have seen in the, in the entire place. this is to attract a pair, is that? yeah. and then they, they're stunned on these buys and then,

but there's none in there. i mean, near there is a pass managed word and even a path up though it catch em. we are picked law fish. this is really to where to this is floating. this is, this is yes, company put a completely floating jack way be created, a po and reno's in upon. we knew pon took it what the far west they were. so i do evil built by upon as a less it here for our system. so i do, can we build upon it? it seems that we had a plan. so i consider is the, is the sim area. we have to put action one, harvest of fish for every 6 harvest of vegetables july. the fish are feeding the vegetables. yes. and the best of those are in a sense be raisin philip fish. yeah. so that, that the trimmings from the vegetables are actually going to feed it. and using is the sim, size of the land but has to pull out yet being located within the city. these high

density aqua clinic setups are also saving energy on transportation and storage. so it's little wonder this guy greens have garnered widespread interests. ro asia, as well as with the singapore in government, continue to support the development of the technology a come back to the woo, how offices to learn more about their living buildings. what lies ahead for ages? greenest city? this project, for instance, when it's fully grown, we'll have 11 times aside area as green area. so why go to all this extra effort to, to swadell you buildings in plants, a huge one in hot climate light. singapore is that plants are the only thing that when the sunlight falls on it, they don't heat up. they actually take that energy and use it for their chemical processes of grueling carbohydrates and things. so the calculation for singapore, for instance, is that before the city was built, singapore was 5 degrees cooler. and all that heat ends up being converted into

fossil fuel use as people use air conditioners to cool the space and throw even more heat out into the city. if substantial plant covered even reducing a pull by 2 or 3 degrees celsius, the energy saving for the entire country would be, you know, in the billions of dollars of use. a lot of the argument, you have the also much of the cities do you know it doesn't matter. one or 2 buildings? what difference can i? but if one building can compensate for 10 other sites, not having any grain, you can see that just by doing selective injection of these kind of buildings for the city, you can already create a statistically significant amount of green in the city. can you see potentially in the future where you could actually see some of this area providing a food supplement because we know that singapore is still relying on food input. yeah, we've sort of done generation one which is providing a lot of planting and achieving these plot right shows,

i think generation to is. so i can now we have this. what can we do with it? and as for i think there's anything you do on land, on the ground, you can start thinking, does it make sense to do that apply on a building so, you know, food. oh, we're also very interested in ecosystems. you know, can, we might have, not just decorative, but can we make it very biologically productive weekend, like in a lifetime, how many buildings can we build? this is something that needs lots of people doing it and it needs rethinking at the urban planning level. and that whole city visioning so we come up to the sky vill dawson, which is one of rich, it's public housing projects and it does feel great. i mean the, the planting design in this shady canopy of solar panels is lovely. but i mean, looking out at the view is pretty terrifying, is not just the density, but is the number of housing and building development projects. and is this kind of

a model of oil tankers and shipping containers that stretches to the horizon in almost every direction. but when you start to look at that horizon through rich's eyes and you see the potential for a rooftop back upon excel, vertical forest, you know you start to have hope. but for us to make that future a reality. and it means getting the grass roots in gaze, it means that joy fair and can we and all those guys get things going from the ground up. and it means them meeting the plan as in the policy makers half way. if we're going to see the, is there truly sustainable as a metropolis is continue to expand, we're being pushed to explore more radical solutions to the environmental coffee living in, ty, one, a french architecture firm is constructing a garden tower, which will absorb a $130.00 tons of carbon dioxide each year. while local government in washington d. c, is utilizing the high foothold in the city center to generate energy kinetically

for lighting, using a technology called paycheck. and to south korea, soto has been up the smarter city on the planets. developing a built the wealth, largest pneumatic waste collection system, city wide recycling is protected to reach 76 percent by 2020 innovations of an if the was supporting funding to adopt them widely as a chance the wells much openness is could become sustainable. and with so many of us living in cities, the environmental impact could be huge. ah a frank assessments this gracious, he's continued to weaken a look a shell out,

even though perhaps he believes in the beginning that they will expect for informed opinions. i think politicians will now be under incredible pressure from the young people. that is one of the most helpful things to come out of this critical debate . do you think i should be facilitated? not sure. okay, it's a great. it's a really simple question. let's give samuel a child wants that inside story on al jazeera.

with all play an important role protecting you with me for, for your gun to his arm a launch. his air and artillery strikes in democratic republic of congo, against and on group accused of suicide bombings. ah, baptism, this is obviously a rely from doha. also coming up, united states warns russia against aggression in eastern ukraine. russia says any nato forces moving into the region with cross or red line. but he says, sudan use tear gas against anti military protest. i was heading to the presidential
