the, the the air is all whole, it's a duty to help take care of it. no matter what field we work in. today we have some, as far as examples of people showing how it's possible to make a difference of crystal lives. in lagos, nigeria, a walk up to eco opry. got your thoughts coming up? eco friendly building how complex in ivory coast. i'm guessing this fat or mental patient maureen, is how scientist in south africa alone and from the jelly fish and our roof with

a difference. how far island is filled with nature in mind? variety has abundant natural. what the resources of steel millions don't have access to a clean drinking supply to make model as well as a lot of the ground water is being polluted by cutting the coals from scrap metal collecting these toxic waste and turn it into something useful is a hot process, but we met some people what not afraid to get their hands dirty. this man of disassembling complex and in doing so, they are contributing to environmental protection in burundi because the smallest african country lots proper waste management or too often all costs or cop parts and up in the environment. rushed on under range of toxic substance pulls that

switch to echo system on human health. but this bucket business is special for change that is happening in the room d. no, it means once these vehicles are this month to lose separate metals such as cost, i own a medium, but it's important that we don't mix will combine them with other materials like oil. we carefully saw the metals for the factory and set aside on the rest of the sizes you actually got to show up 2 years of neglect. recycling you've gaining traction in burundi. people are realizing that's what he's conceded ways can actually be a valuable resource. jordan could be mine, i will run this trip. he knows that's raising awareness is key still get a little good idea of who get i want to go by my friends. you need to explain to the village of the dismissal with these very to interesting and not handled properly,

that have positive that's caused by such waste. we need to collect to, to, to on money and protect the environment. when the bruno relies on leg tons a new guy in east africa, holding 16 percent of the plant, it's fresh water. it is the 2nd largest lake by volume in the world. but littering and the lack of recycling facilities affecting the ecological balance and public health around the lake dress with that's being dumb to close to our data, to the into reverse east, particularly concerning as the to complete the drinking water of millions prefers. uh right me, marie, includes in the detective toxic heavy metals and drinking water samples. a full affected to get ahold me. oh, interesting. when it comes to human health. so key we need to money to heavy metal is particularly lead acidic pro mercury. and on cut me and

medicaid and affecting young these heavy metals come close to via immune deficiencies, infertility or cancer? a little to hello, hello. this is so thank you ladies concerning because it is casino, denny can is found in the lake water castillo d like it came across some lift. tundra nichol solves is a fresh water source for 95 percent of people living in a boom or a and other towns by the lake like ramon good and nuns like so. so it's for me to use it on the left and then you can add. so this is of the device that we need to take seriously. it's important that we monitor the increased levels of leads and other heavy metals, any like time that need to be set to one month or so, the pool would be able to meet total. that'll do not collect these crap mentally and recycling cups like this one. and she was that valuable metals are being reused and more importantly, the vendor

a substance as don't pollute the drinking water for millions of people. but raising awareness is not always as easy as it might seem, in theory. quite a bit of a joke with and is this look request patients we have to go through villages with crop of metal is cut to then some people are reluctant to talk to you that you're having to give them one of those judges team prepared. today's delivery for their customer. the collected metal ends up here in these still plants run by on experience company. best in india. via the recycled metal, get sorted once more with the help of heavy machinery. and eventually melted down and molded into new products each day, the plunger cycles 40 tons of metal into 2 buzz which comes in be processed father

. the, the most popular product of high quality is to as well as they are commonly used to build reinforced concrete building. the roads meet international standards and they are also deployed on construction sites closer to home like this one next to the company. and here in the suburb of mushroom, where there is for the proof that an old guy can have more than one life. some of the plants materials up less goes to these metal craftsman will make kind of crafted, cooking parts installed. what was it that i'm being look for? i didn't, but how many um uh, who gets krupps and sheets from the plant and we used them to make our products. that's much better than polluting the leg. can i get? of course a lie, you will not. i'm one of the kind of him,

but i should have already cut off one minute. and the cost too much seems satisfied . vc money is happy with the new store for how business mit entirely of recycled materials. the increasing when is raising and it's probably some of those small recycling businesses alongside major industrial facilities is a huge improvement and helps reduce pollution in burundi. promotes and concept visual needs using the densely populated and growing country is crucial. pruning and government and the u. s. environment program wants to set up more recycling facilities while the european union. these also helping to set up a network of what's a quality monitoring stations to keep the world's longest fresh what to look clean . and it's biodiversity being taught the waters of this saw the atlantic ocean ok team in that species of jelly, fish, these creatures. i've been around for hundreds of millions of v as yet there is

surprisingly lead to research into them. now, scientists, the south africa, a trying to find out more ball them and the critical role the play. let's take a deep dive. jelly fish are among those oldest inhabitants. mass occurrences known as blues of jelly. fish happened roughly every 10 years. but in some regions, like allowing them to be being caused, they seem to occur more frequently. but it's hard to get dot to jelly fish thrift with the current which makes them difficult to accurately record. such invasions are usually the result of environmental conditions which leads to a drop in the number of predators. at the same time that can be facilitated by an increase in temperature, you can increase the temperature. these things will grow foster. you dropped the concentrations of oxygen that will affect fission negatively,

but it doesn't affect jelly fish. the jelly fish will drive in areas the fish of being forced to events. the invasion has not yet hit south africa. chris lewis is a jelly fish expert who is familiar with the species in the waters off cape town. so far, 20 spaces, a note here, such as the pretty mouth jelly and the poisonous fox jelly fish. researches are only now beginning to understand the role that these invertebrates play in the marine ecosystem. they're not only supposed to indicate the spaces to show us when it goes system is out of whack. but they also play be important at all. that's a pace pcs, as well as criticism, notion of because generally companies does the actually lock up a lot of carbon into the ocean and we literally fish die. they actually sink to the bottom of the sea floor. and then the following season with the wind induced operating that you didn't get to the used for by the effect of like me in order to grow and start that cycle back again. there's a lot more to learn about to species diversity, to varying. a ross has spent just over a decade,

studying jelly fish together with other scientists. she wants to build a database of the different types found off the south african coast to determine whether there are any changes in the numbers. but it's a huge task. it gets small, but 6 tissue, we expect that issue, we get to be in a, out of the tissue and all that place these, this little solution. fold it in a. what we then do is we sequence the d n a and we look at what species we are seeing based on the d, n a. and we are discovering many, many new species. and so this has been very exciting for the more the researches understand about jelly fish types and the numbers, the better they can determine changes in the population. and carly them with climatic conditions. can you fish certainly seem to feel at home here as the coast of south africa is one of the most species reaching the world around 10 percent of our jelly fish is live here, and many can be seen at the cape town aquarium. each species has its own peculiarities, with some only living and cold water,

others in war. chris lewis is responsible for breeding them. it's a complex and difficult task. each bases has its own parameters. so while they're creating up some spaces, one to the in will cove with the specific periods of time diet shift, we have some good appreciate me. as a genius patient, we actually have to produce enough to push in order to feed them. then also some databases aren't very long left, they left for 6 months or 9 months. so it was nice to have this fund by about system where we actually getting use pieces to replace the ones that actually expiring on exhibit. many people are fascinated by these aquatic dinosaurs or few of them because many gigi fish are poisonous. although only a few species are dangerous to humans. some jelly fish also contain highly erotic assets and important nutrients like protein. making them popular food in asia, but they're not on the menu in south africa, yet. instead, scientists,

you hope to better understand the role of jelly fish within the marine ecosystem and how it's affected by climate change. now we had to pop long european, a post in the north atlantic ocean. yeah. so there's no construction mass thoughts, how valuable they can be in the fight against climate change. yeah, there's today's doing your big it's not your average law that runcle hakes that is mulling per house has a traditional turf roof. it's a method of insulation that dates back a 1000 years or more, the village of goss a dollar as close to the cliff edge on one of the pharaoh islands. position far out in the north atlantic. stables built centuries ago by sailors and warriors, combine kings are still in use. we always try to make a small and print

a new environment as possible. but this has to be a good way the federal islands line between iceland and norway and one of the most remote corners of 0. they belong to denmark. the 18 islands are home to more shapes than people do to the harsh climate and send layer of soil or a few trees. but there's lots of grass with strips of turf. provide. installation this restaurant isn't tor shown. the pharaoh east capital the grass roof or blend into the landscape. and that's not all. it is not the, it's not only beautiful. it's very, very good far for isolation and also very good for our for nice reduction. and we had the hail and, and rain and snow storms. you can hear nothing at all on, on the roof of the as green roof can absorb around 2 kilograms of c, o 2 per square meter. each year,

these living tiles convert carbon dioxide into oxygen reducing the climate, warming emissions, the local architect. heidi thompson, is delighted that one of her favorite building materials can also play an important role before just once, you know the material, you know on the roof. now with the tool against climate change because sucks of sect uh has a huge carbon footprint and an ivory coast largest safety. i'll be john architects and urban planners are working on a square metal energy efficient homes and public building as the vault to see. it's also important to find ways of getting up such solutions fast, the sustainable construction as a promising and pulsating future in ivory coast. we looked at innovative approaches

in oven planning on building design aimed at making city life green. on e to construction project taking shape and i'll be john division of this month here in alba to on the outskirts of the city architect. you said d of i to a is really developing this 3 heck to area with apartments built with a small, a competing footprint. that meant plenty to incorporate a range of environmental features such as natural cooling instead of air conditioning. so silver has its open here and then open pay or you can feel the airflow so we know it's hot outside, but inside here it's not as hot. and we can feel that there's a difference of $2.00 to $3.00 degrees. built full meters above ground due to the threat of rising sea levels and flooding. the district real feature shared green

spaces, irrigated by rain, water harvested on site. plus a selection of stores will cut background traffic. sustainability is a priority for the architects. this explains the focus on apartments compared to houses to consume a lot of resources for a small number of residents. you want to know if, if we continue in this direction, that phenomenon will become more pronounced is so i think it's time to start thinking about the city in a different way. so especially now that we know how we could create a well thought out city and i'm interested in visiting the site would have had enough space for around 50 detached houses. instead it will send the home to $36.00 townhouse apartments on a $190.00 regular flats. although they do cost an average of $200000.00 euros. it's a far cry from the 1980s when the government built a number of new neighborhoods in abi john with small residential units and stores.

but that changed when the construction sector was privatized. and of i'm planning, joining the free market. the key element of sustainable building is of course the materials one company has upgraded the traditional brakes to create a higher robust mixture. read a sound more to on the little cement. i'm going to do it before we had a the concrete or had to present. so by hand today there's b, t, c as a stabilize compressed as glove which is what pressed by hydraulic machine. that the differences in strength to your concrete is not as resistant, has made easy as if i get out if it was the brakes, little bike in the sun for 7 days before they can be used to construction on site. they into a lot like self looking panels that then put teeth to reduce the gaps, the only time more to is used. it's

a foss technique that also provides better insulation. a lot just a little just to so many stocks in ultra violet rays and send some back into the room. i see the but the clay in the last ride that may cause a taste he has left the res. so the heat outside, hot guessing, and it stays cooler inside power. there is still one challenge training. most workers have to acquire the requisite expertise on the job, but it's quite new to the general supervisor picked up the technique, not during his studies, but on building sites on the corporate office. it might be, you do it up when i discovered this material. i honestly didn't believe it was, but when i came to see for myself to see the methodology, to see the practice, they used to assemble this block, which is truly a jewel. it was really extraordinary seeing that a building could be erected right up to the finish without cement you start off with yourself, saw some stuff my boy and students can learn

all about future oriented building, not in. i'll be john. but on the eastern edge of the country in the small city of bundle university that teaches evan planning, and he co construction in a cost sponsored by the wells bank. so many students, it's uncharted to write the best and the most. i'm just discovering it now. so it was originally just the passion, but i didn't really know what was it. stay now is my studies progress? i understand why it's important to be able to building a sustainable and they can logical man out you can use profess up. yeah, dicky is trying to make them aware of the importance of collaborating with all trades and disciplines in the future projects. let's click on preventative look. monday, when we talk about assessing cannibal development, there's also the economic aspect into so while the economic players can should and must work together, i love to get them done. then there's the environmental aspect. meaning to all the

decision makers, they are to need to work together so, so say come a, you know, so yeah, it was a human and socio logical by us back as to the, for the cities of tomorrow. all the disciplines have to try to work, not independently on their own, but in a complimentary way. you do mine? yeah. a complete monkey. in 2022. the will find introduced assistance occasion system for sustainable low comp and building the edge label is avoided to contractors that meet a series of criteria such as minimizing both fitness and use of building materials while maximizing the availability of natural light and efficient installation. with full features being checked during construction, those who receive approval can apply for green building investment for funding from planning to certification on completion. a range of product to the initiatives that

off to get the pos forward. the sustainable of i'm planning and not the john climate change is speeding up because human activities really isn't goss, is that he tell the atlas? yeah, i would create extreme, a little predictable with it can make farming, very hot as the reason flooding in these. yeah. show what was that to meet a woman who is still managing to grow in great sustainable pros. use secrets. know how adaptability as she had work she has created a leaky paradise. resting to hector's of greenery, from the sense of the village of 20 via northwest of new. she has cup told me a may have you name is a do the rules. can everyone hear cold tend to rules for the past 15 years, she has been cultivating this piece of land,

but in a unique way, the shell, it's the she i chose to pursue ugly color g simply to protect the environment because of dismissal. i love all the creatures, be careful. full is it with me so i know such as animals i knew living beings and people to live in caustic symbiosis. same here. still an exceptional approach in this year. there are almost 15000000 hectares from land covering just 12 percent of the saw head countries surface area . even though 80 percent of the population depends on the guidance or small funds for from the 20 of roles has gotten is an example of the secular economy. she just cuts nothing. she feeds plants scraps to her chickens,

which in turn has helped produce organic for to lies. to compose tips are tending it to sort of nutrients on her land. with 10 people results she have is up to 300 kills of let use a year every week. how produce is sold at a small market in the me a custom of the off the pleasing fragrance of fruit and hubs. and the last one and the difference between him means and the means of the market. there is enormous. when you just bring your hand close to your face, you're overwhelmed, but it's high quality that i received due to an applebee's. but her last walk was under threats by the end of august 2020 for the breach flats, albany. she had visa had reached thailand and even dated, had gotten along the river. she was in the process of hiring to booking up and labor. as when the catastrophe struck knows that

it is a new color when she came to pick me up. she asked me if i knew how to get in there . i just told her, just give it a try and we'll see. when we go to, the water was rising and almost half the garden was flooded. but as you can see, the, the result has not received it a lot. and since then we started walk. so it seems a little i don't lose kennel hasn't given up the 15 year old we decided to turn the challenge into an opportunity and try something you can do for the month. like i used to grow so much was the state of rice. unfortunately, this year with the floods and the water rising from the ground, if you had to go right from left. so i'm waiting to see how to turn out for me while waiting for the rice to ripen. she was to the other major project most on the

planting for, but also for assessing it such as he discussed drink called be something to use in west africa. it's do you know, no smoking the but she's about to realize her dream that this is the factory that's under construction. the just production plant. it's a small unit. it's not to think she invest everything she owns recently she installed and irrigation system to show that planting and how this thing food is possible, even when the rains don't come like things use to do to climate change. her solution to that challenge is ecological summing. tend to roles, has become exemplary. now i did edit say to have written st goes like rose, all while you please do get in touch. have a good d, w dot com. you can also find moist virus stories by searching for eco africa online . so now it's good bye for me, chris, that lives in lagos. nigeria,

thanks for watching. i'll see you again says the or the

the some people don't care about me because they don't see my beauty. some people don't care about me because they think i have nothing to do but to be in to, to do to them. i am everything at home. they have food then life day by day i do so. and so does everything 92000000000 people came about me. me me. and now i mean the
