more transports, more buildings, more waste, more pollution. as with many of those moving to cities of rural pool, they joined a 1600000000 people living without adequate shelter. it's vital to define sustainable ways to deal with this rapid itemization. am julianna shaw the columbia, where plastic waste, instructing new home for the for in the vulnerable and i'm russell beard and singapore where one metropolis is striving for environmental sustainability in the face of rugged openings ation. bob. just gras. yes. in over $300000000.00 tons of plastic is produced each year with only a fraction of it being recycled much of it ends up in the landfills, our 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 oscar manda, an architect and founder of a new enterprise for environmental change called from depth of glassy clothes. 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, shall fall. okay. oregon waiters, plastic, google, yahoo, dot com that'll chancellor canyon was 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 of these plastic in order for oscars enterprise to succeed though. he's going to need a lot of plastic he'll 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 rent 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 . on video, the emotional shaquanda, sawgrass, the saw a little bit. he's always cucumber sellers, glenda burlesque, hardy's in color d does. it's all rosa sandra's gland, the ongoing challenge for paulina and his team is getting the word out

loud to one another one as well. he comes almost at the other day. and when will this be gone? ted dubin goes, you know, the one bedroom. okay. recommend a by the police. yeah. a way of knowing people until they was like a month with me. same with it given was i do, i don't me. i'm being a celebrity model that is like i was like in the job secret i'm yay, thing that a little bit as you on the almost somebody else is almost like on the spot.

ready 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 a perspective saying here, this is where we take all the plastic from paulina and maybe the 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 he could be like, just come straight from the factory, but these haven't even been used. it's like a giant lender. what, what to this packaging? if you aren't recycling it, sold it because you forced consumer or assure 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 has. oh sorry. okay. this is the shop. they won't. 7 tell us exactly the proportions cuz the secret wrap the piece, the ground plastic are mixed together. heated 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 my viewpoint. depends of the me is, depends on the block between longer and longer at 40 degrees in 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 heavy, but it 30 i wonder what that was for that or that a cell phone numbers. we have another 51 number for. so now that we have all of these breaks, what kind of uses do you have for them?

emerging were, you can made the same being with this kind of went through and where are these going? this weeks are going to gully. you see what we're going to do is recognize globally as the world capital for salsa dancing. the city of cali, 400 kilometers west, of all the thought is one of great social 56 percent of the land area occupied by slums housing, 40000 people a most godaddy. bob, give me a quick come through and by gather i'm neighborhood in mr. paling one of the cities most deprived areas. oh yeah. oh phone. yes, i do. gotta read them 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 was here in the community. i feel as i thought you were in bogota at the plan, we're 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 them? sure. yeah, this is the bathroom. mm hm. this house cost $5000.00 and has been micro financed by the community for elfaire me out. whose son lives in the apartment below. where from your market and ya, not vieza for an um star and were not going this unit. aha. see cadillac on 6 young? because as far feel, boys today will 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 must come through the the natasha into the law that he just here. so in into the plastic or the cloud that rocha

looks like rock to them. a government with a story about, i mean, i mean you need to let me get this . i just can't get over the holes for the electrical outlets in the plumbing wire. the cable down in ohio, 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 going to be here. i with the television on top. if you can imagine that the all we've got left is the roof and some doors are pretty close. how much plastic is in this house? this house we use is 5 pounds teen compact thought as a plastic or where do i say to my son? was it the minute continental that what interviews a little bit. okay. okay. i do. just let me,

let me call 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 i look on his daughter into mrs. imposes is working with employee. amazon. me comes up this class 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 the waste plus in the war. we can change life of millions of people . we can finish their house in charging like in america, in just 10 years. that's an enormous number and a huge impact. we have to start, we have to start my step. ah, i mean,

what tentative, sustainable building materials are being 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 my case. number is one of the 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 cake. this uses coal and wood i. she's a filler, instead of sand making use of waste that would otherwise be buried in the ground. and, and caused amana one nonprofit to spill to school using natural resources and rubbish that would normally pilot landfills. reservations 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 habit.

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 urban ization, 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 doug h's, cleanest 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 this stewardship of the when you look at like google earth or images from spike, 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. the singapore in goldman awarded talked while 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 the cities, the greenest in asia, i want to see what's happening at the grass route. heard about a non profit trust and providing environment and supporting accruing unity. i've come to be the funder like hope. and 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 digitalization. that's when you come disconnect. so i was trying to create, using a space to connect back people and to bring by the spirit of the community. and it's very strange for a country like single floor 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 guess it just for a moment, forgot that we're in the middle of it just knocking down your door. and if you 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 choice and incur we volunteers have come along to get their hands day way. see yourself doing farming in a way i get muma connected with what we are actually doing every day because 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 the fruit is growing. maybe they thought it just from the 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 big, 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 paper, i start to think so way that from and if i troy away, is it going curve? we're committed to reducing are ways to almost 0. we go back to reflect to see if she's good at all. 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 who st. paul into it. yeah. 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 53500. 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. have we in the journey to 0 waste community 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 dress which projects us sprouting up throughout the city. she met chafing earlier at the 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. yes. my neighbors will come and spend time here in the garden. i need doing stuff. the ad directors, the 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 this open spaces and sing up bar should not be hot. the cow chair

landscape, it should be foot space. and how can mean, surely me sing up or maybe a, a city in a foot 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 to 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 confirmed nervous, uniform like this before. i was in the world 1st in the washer. 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 the best ever think about and we stay in the history. the fact is,

is that because he thought of it why i wish they were out because i cannot go. but the study candy, our system is using the hydraulics are using wiper, make it this power or dating. so fun can go up together in our sunlight. can now get our new trends in what so and the water is a similar though, miguel rotating as a sim. also give a thought, a plan and the what i will be q one, at least i can use it so far. we not change over at all so far. you've not changed it at all. weiss, 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 me, there is a past managed, 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 the completely floating jack way, the created a po and reno's in upon. we knew pon took it what the far west they were. so i do, if you built my upon as a less it here for our system. so i do, can we build upon and assume that we had a plan. so i would consider is that is the sim area. we have 2 products and one harvest of fish for every 6 harvest of vegetables, calais, 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. i have to pull out yet being located within the city. these high density aquatic 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 of 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 a live in time for thought 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 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 was 5 degrees cooler. and all that heat ends up being converted into fossil fuel use as people use air conditioners to cool the spice,

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 that's where i think there's anything you do on land, on the ground, you can start thinking, does it make sense to do that on a building? so, you know, food or we're also very interested in ecosystems, you know, can, we might not just decorative, but can we make it very biologically productive. we can 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've come up to the sky vill dawson, which is one 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, 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 riches eyes and you see the potential for a rooftop coupon, except 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 choice 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 cities, they're truly sustainable. as our metropolis is continue to expand, we are 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 governments 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 done the smartest city on the planets. developers have built the wealth, largest pneumatic waste collection system. citywide recycling is protected to reach 76 percent by 2020 innovations with an if the, with support and funding to adopt them widely as a chance the world's metropolis is, could become sustainable and has so many of us living in cities. the environmental impact could be huge, whether it's cute and totally in australia, wild and ferocious in bangladesh, birth rise, we dress is the balance between endangered wild life, and then noisy neighbors that such about forest right there. and there's nothing between a human habitat learning to live together on al jazeera, how many people here have seen a tiger like they had to, oh,

really is a ah ah, and assassinations in broad daylight and increasing moderate towns and cities living in fair al jazeera world, examines the rise and criminal gangs and the palestinian israeli community. how are

these violent crime syndicates operating? and are you ready authorities doing enough to combat them at palestinian israeli crime waived on al jazeera. oh, this is al jazeera ah hello money fight. this is the news i lie from doug hall coming up in the next 60 minutes cases of the new cove at 19 variants a found in more countries with the weld on a lead for the strain 1st identified in south africa. israel is closing its borders to all foreigners for 2 weeks in response to the new variance. to dawn says 6 of his soldiers happen killed during.
