next 40 years, cities who gobble up natural habitat. the area covered by triples, will people means more transport, more buildings, more waste, more pollution. as with many of those made into cities of rural pool, they joined a 1600000000 people living without adequate shelter. p. it's vital to define sustainable ways to deal with this rapid nice ation. i'm juliana the columbia, where plastic waste is constructing new home for the, for in the vulnerable and i'm russell bearden. so you're poor. we're one. metropolis is striving for environmental sustainability in the face of rugged urbanized asian, p as grassy as in over $300000000.00 tons of particles produce each year with only a fraction of it being recycle. much of it ends up in the landfills, polluting urban living environment, waterways in ocean, in columbia,

tons of plastic waste has been diverted into the building blocks of a new environmental housing pollution. a column is capital city above is home to 8000000 people, and it is estimated that 650 tons of money is thrown away every single day. i have come to meet oscar mendez, an architect and founder of a new enterprise for environmental change called from separatist lassie, cause 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 one, we'll be lucky, give shall fall. okay. oregon place where is plastic or yahoo dot com. but those channels are kinda those onions. 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. we can transform all these plastic in order for oscars

enterprise to succeed though he'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 bog, 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. read or looking for paulina. he's the lead recycler, he's organized all of the recycling 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 and video. the emotional sequence of glass is fine. gonzales cookies. i see lucy glenda. what alaska is in gravity does. it's all rolls is fine. but as the gland, the ongoing challenge for paulina and his team is getting the word out

loud to what i was working on a slow leak coming almost the other day. the son who normally be gone. ted dubin boise knows about. bugger mckinney reckon tomorrow, the i wonderful dea. a way of knowing people and so they was like a month with me. same with if given was you out of me? i'm being a celebrity middle, that is like i was like in the job. she did the thing that

a good as you on the almost some of the, the other school almost like on the plastic was, is 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 i think was a perspective. thank you. this is we're, we take all the plastic from pauline all on negative information. over the past few years, oscar and his team had been refining this waste 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 see like just come straight from the, the battery, but these haven't even been used. it's like a giant lender. what would happen to this packaging if you weren't recycling it? so the packaging for the consumer, or is your, is going to london. 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 about, sorry. this is the shop they will tell is exactly the proportions credit. the speaker, wrapped with the grand plastic, are mixed together. heated and then compressed into brick shaped mall. tell me, was it about the temperature? what? how hot are the plastic? we just get them as you point, defense of the me is depends of the block did between longer and longer. at 40 degrees, it is very important that the temperature is kept 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 magnet. not as happy, but it 30. i wonder what that what are that are that boundary of telephone numbers. we have a one another by one number vol. so now that we have all of

these bricks, what kind of uses do you have for them? imagine would you made this st being with this kind of work? and where are these going? rigs are going to gully you is the word we're going to deal with, recognize globally as the world capital for salsa dancing. the city of cali, 400 kilometers. west of bova is one of great social divide. the 6 percent of the land area occupied by slums housing. 40000 people, a godaddy. oh you give me a good weekend to end by gather a neighborhood in mister prolly, one of the city's most deprived areas. oh yeah. oh phone. yes. but to got them removed and ill from your leaders upstairs to catch up with oscar ellis bricks. wow

. oh my goodness. the bricks, me just thought in the factory they're actually constructing into a house for someone who is here in the community. i feel, as i thought you were in bogota at the plan, we are building 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 he has. this is the bathroom. this house cost $5000.00 and has been micro financed by the community for alpha mia, whose son lives in the apartment below. where miramar didn't ya? not be as honest um with our and were not conditions. ah, see, get the lack of it's young because it's fussy boys to their booster said, 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. it's the law that he just, chris. 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, you'll need to get with this. i just can't get over the holes for the electrical outlets in the plumbing wire, the cable down in a non electricity. so check 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. no less. i'm 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 to rough. how much plastic is in this house? we use it 5 pounds. teen compact thought as a plastic orb with us here to was on one of them on your own. quinton,

out like what interviews with in just under today's 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 to help us out until the amazing phones is working with employee. amazon me concept is less because have already helped to house 42 families displaced by conflict in the town of why fi, 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 insurance as you look in america in just 10 years . that's an enormous number and a huge em hagi. we have to start that. we have to start step by step. ah,

what tentative, sustainable building materials have been developed globally. bamboo is been 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 of 4 to 5 years. bamboo 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 green take. this uses colored wood ash as a filler, instead of sand making use of waste that would otherwise be buried in the grounds and, and caused a mala. one nonprofit is built a school using natural resources and rubbish that would normally pile and landfills . the organizations made assistant out of old 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 spaces we inhabit

singapore is a low lying island and city state. 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 20, the 13th by ward winning architect, which it has 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 suggest wise that building projects can also play a much stronger role in june ship of the earth. when you look at like google earth or images from space cities or really does it, you know, you see a very bright white, shiny area surrounded by documentation. if people build buildings like this, you would no longer see that you would see the vegetation layer covering the city as well as singapore, in government avoided talk while it's coveted, platinum, green mark, the nation's highest environmental city location is part of a white, a scheme to promote environmentally friendly buildings and investment into green city solutions. to understand more about why the city is the greenest in asia. i want to see what's happening at the grassroots i've heard about a non profit cross tenants providing environmental education and supporting accruing into community. i've come to meet the funder light hawk. com and i came

here trying to get people to go back to basic. and i thought as a result that we've of a nice asia globalization and digitization. that's when you become disconnect. so i was trying to create, using a space to connect back people and to bring better spirit a 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 the shape. the 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 environmental, engage citizen. i gave it to you for a moment, forgot that we're 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 do you think will become where a full coming from? who wants to work on the land? who will clean the rubbish for? you are designed by malaysia in the ground up initiative gardens or meet troy friend and co way volunteers have come along to get their hands dirty. why do you call doing farming in a way get me more connected with what we are actually doing every day because whether it food we know exactly where they come from, anything up. i realize also people don't appreciate food because on maybe to the kids they have never seen this. how the fruit is growing. 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 heavy or the tech stuff, but really been able to,

to understand that you, i just be what a part of this legal ecosystem thing, how things are growing. for example, it makes me start to ask a lot of other questions like how, where things come from. so if i use a paypal, 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 on. this is the last place that you would expect to see a little permaculture garden going on in somebody's front room. i just thought it this journey barely a year ago. so a lot of things are to me are experiments. do 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 in singapore i on. when i saw that a group on facebook, it was sometimes frustrating because i seem to be the only person who kick 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. a technician can we, in the journey to 0 waste communities still have a long way to go. last year, singapore is 5500000 population. ditched over 7500000 tons of waste. that's one half tons per person. but momentum is building and similar address which projects are sprouting up throughout the city. we met jason earlier as a ground up 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. yeah. my neighbors will come and spend time here in the garden. i need doing stuff. they add directors, i am c o lawyers. is that, is that a demand? me is that so i never seen soybeans group before. i feel that a lot of just

a bunch spaces and thing up bar should not be what the culture landscape. it should be foot space. and how can mean, surely me, singapore, maybe a, a sippy in a foot godaddy? why does it need to just be a small one in one day 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 have never seen a farm like this before. i was in the well, 1st in the world for someone that's never heard of a vertical form. how do you describe something? i think a boy landscape. so we don't have much our land thought of what he was the best

ever think about. and we stay in the history. the fact is, is that because he full of it why i wish they were, i could contact go, buddy, handy. our system is using the hydraulics are using water, making these power or dating. so pan can go up together in our sunlight, can now get our new trends and what that. so and the water is a similar though. miguel locating is a seam, what else will give a good plan? and the water will be q one. our lease fica use it so far, we need to change a water at all so far. you've not changed it at all. worse. 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. meet and i play king of the veggies is a beauty. is me or look that we'd 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, me, there is a pass, many vanish work, and even a pass up though it catch em. we are picked our fish. this is really to where to, this is floating. this is, this is yes, company put, they completely put jack way the create a po and reno's in upon. we need pon to get what the far west they were. so i do, if you look back upon as a less area for our system. so i do, can we build upon at the same time we had a plan. so i would consider is that is the same area. we have to put action one, harvest of fish for every 6 harvest of vegetables, collect the fish are feeding the vegetables. yes. and the vegetables ernest can speed raise can fill of 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. i have to pull out yet being located within the city,

these high density aqua, chronic setups are also saving energy on transportation and storage. so it's little wonder this greens had gone and wide spread interests ro, asia, as well as with the singapore, in government. continue to support the development of the technology of come back to the wo, her offices to learn more about their living buildings. and what lies ahead for ages greenest city. this project, for instance, when it's fully grown, we'll have 11 times the site 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 like 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 the chemical processes of building carbohydrates and things. so the calculation for singapore, for instance, is that before the city was built, singapore with 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 cover even reducing a poor by 2 or 3 degrees celsius, the energy saving for the entire country would be, you know, in the billions of dollars over the years. a lot of the arguments who have the all so much of the city is built, you know, it doesn't matter. one or 2 buildings, what difference can they might. 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 or we're also very interested in ecosystems, you know, can, we might have, not just decorative, but can we make it very biologically productive. wheaton 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. ah, 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. he was 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 for it's 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 the choice. and can we and all those guys get things going from the ground up. and it means they're meeting the plan as of 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. some dough 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 metropolis is, could become sustainable. and with so many of us living in cities, the environmental impact could be huge. ambitious endeavors to create drought proof crops. amazing to think that the plant be so earlier that look did now look completely alike and international efforts to combat the pest script threatening. so they bring in their samples, they show you the property. yes, just like an adopter, right? your prescription, you're doing the same thing here. you're writing

a prescription for the farmer offline explores inspiring advances to farming for the future. al jazeera johnny has begun the faithful world copies on its way to catherine book. your travel package to death. hello, we got the usual lie, be showers cross northern part. so south america is that called plough their cross northern areas of the amazon pushing up towards the caribbean. much of brazil is dry and fine. you can see this weather system here that is a cold fronts and that's been making its way further northwards and eastward. it smooth for, with sunshine temperatures here, down around 10 degrees on what we saw just a couple of days ago. it'll make his way towards rio that he to celsius saturday afternoon, 22 on sunday, so that cold front sweeps through, clear a fresher weather. coming back behind. mister one or 2 showers, plenty of lively showers, of a tropical nature. further north and some pretty wet weather for the north. still
