the, the climate change can jeopardize and tie economic sectors and take away people's livelihoods. but in many cases, sub solutions can help us to adapt ad opportunities to make life better for rules. welcome to a new edition of a cool africa. i'm presented loads an idea once again. we've got the pack show for you today. let's dive straight to coming up. empowering goals. how us so lombard backpack is changing lives

a row. you can feel real as food safety dwellers reach steam, pollution crises. we haven't got it. installed proper got past, we'll meet a woman by you now read eco friendly trust collection of recycling in kenya via a smartphone. now can you imagine catching fish with palm leaves? it's part of an issue. and fission bustled used of tanisha is kick in the islands cold shop. the odds, especially in the environment to me frankly come join the also to see how echo offer eco went there to watch these amazing technic of the sea is on a couple 2nd time today. he's once again heading out to go fishing, using an angel technique found only here on the kind of items of tennessee is east coast. it's called sophia and involves catching fish with the help of palm fronds.

almost shortly for lenny i'm, i've always worked at sea. when i was a kid, i went fishing with my dad and the 3 of them behind. and when i finished my studies and returned home, i automatically went back to fishing was done in the past. each fee a is arranged as a triangular barrier. the palm fronds can be seen and the shot a waters around the archipelago. the fishing technique relies on title currents to drive the fish into the trucks. unlike fishing troll is the shawl fee a don't com, the marine environment. instead they present a bio diversity. they have an answer, but i think, but i think the problem with the dragnet says that they don't allow anything to escape with the palm branches, fish, find holes to swim through every hotel and doctor's treating people. it's friend. i mean guinea does is also on board. he's not a fisherman,

but an artist. and he's fascinated by this ancient fishing technique. traditionally, it involves the use of date, palm branches for guinea does they to a part of the kind of islands, cultural heritage in his studio, he creates various products to sell using different parts of the palm latrina here by the basis of the care, can you instruct c, a is a cage that inspired me to create decorative objects for indoors and outdoors. i tried to retain the original look how was i that he sees himself as an ambassador, official, fia, in 2020 unesco, declared it pulse. if you might have to use intangible cultural heritage, it's also linked to angel traditions and cultural practices. up on, i was using this method as a basis for my project without really knowing how it works. once i learned more, i fell in love with the c panel,

but times have changed some now use plastic traps is that cheaper. others have abandoned, the practice altogether is time consuming. and industrial fishing has decimated fish stokes. so the whole and the shelf you has also plummeted, but some fishermen are actively campaigning to preserve the tradition, especially because it works in harmony with nature. and the palm branches get fish somewhere to hide and live. it's an ecological method that preserves and respects the environmental health via this fisherman. the lead shot fia will continue just on the test of time us the fish cool this way, a far superior to the catch from industrial fishing. good. what's the sure brought to ensure a live? that's why they're considered to be of better quality than those caused by other means. you know, in physical and high quality fish is an important source of income for the archipelago on an added tool for, to raise to visit the islands. but for allie,

a couple, sophia fishing is more than a trade. it's positive, good can, is unique cultural identity. that's now at risk of disappearing. well, let's look at the past all our ancestors how to shop the system and if the view you come in, they would build it up over the summer months. it shouldn't them. but today, having a shots here requires significant financial capital and affordable money that many unable or unwilling to invest. and so she fishing continues to dwindle, even though it's so sustainable. that's why climate change poses huge challenges for many economic models. reducing the impact on the environment can also be a business opportunity, generally making a difference. well, also making a profit without heads to kenya to meet one very resourceful woman with

a vision to promote a secular economy of social enterprise, collect waste, recycle plastic, and these torak safety of them bustler. and it's all done with a mix of old and new technology or an ad for trash entrepreneur. table hygiene e wants to use it to reduce plastic pollution in mombasa, anyone can register to have their plastic waste collected from home. you are able to book waste management services on the go on the mobile application and using authorized waste manages. then you are able to trade or do nature plastics and we have full cash incentive. kenya's coastal city is drowning in plastic garbage. it's trashing up the streets and polluting the ocean a year and a half ago. table hygiene e started her own business because the city wasn't providing adequate sanitation

surfaces. one of the major challenges in most a county is the indigo dump. think of mix plastic, wasting open spaces. she's providing incentives to counter this by paying participants, depending on the type of plastic about one euro for 10 kilos. for business now has 10 full time employees. first they inspect the plastic to make sure it's been properly cleaned and sorted by the apps users, then they weigh it. finally, they shred it with an eco friendly shredder that runs solely on muscle power. the startup cells, most of it's collected plastic to businesses who further process it. the shreds can be melted and molded into plastic boards, like those they use in their own hand cards. the startup has already collected more than $11000.00 kilos of plastic drink or pilot phase. we've been able to on board more than 1608 use as onto the mobile app. i'm in in old town in cooperation with

mamba county department of environment and funded waste management. we've been able to collect ways from about 6000 household, one of the house he has later to be seeing how successful this project has been. filled me with so much joy and pride this phone and may have caustic sunchase. these little packets might be handy, but they quickly found in the garbage bin and they don't roles. you know, web special, we chose the journey of such, assess, shake from the origins that the rule materials it's made from to its ends on the rubbish sheet. we find out why the number of such chase is growing and why that's so lucrative, so businesses and so disastrous optimists. find out more at d, w dot com slash plastic. that's one impressive woman. and we have both to meet and now the basics. equal hero comes from uganda for more than a decade, a non profit organization has been empowering girls to take control of their lives

and become king, make cuz she has developed a small bag with multiple functions to make it easy for girls to go to school each day us to do the studies. when the sun goes down. the young woman eagerly await it, but fits no visits by naples or relatives shone canyons. and de leon, i'm would you have an order with a customer the the to soon the technicians installed a solar module here a little while ago. now the light bulbs are flickering properly due to the intimate flow of electricity. they have to find out where the problem lies. the job gives them new prospects of good some money from the, from the system. like to is so they, they what says enable us,

that we have really, really a message the, this process. so for you to the main, the force seal fuels into the main. so that's the, to initiative this. the susan, the tuneful also benefits from solar energy. but in a different way, the 15 year old school go onto the backpack with an integrated community solar panels. it can charge a lamp. this helps the study at night, in turn, the lumpkin load for the cell phone. they said that the safety trade may looks at tonights. you don't have really just the tomb. as you see . he says, so have me to send me a whole nice. i'm going to pass my exams. the 3 young woman with introduce concentra, mula, my, and just social into a premier from the yukon and capital compiler for the experiences with solar energy

. my on jetta self gets involved when the employees look for plastic bags on the side of the road. as a solo backpacks, a made of recycle plastic garbage is a big problem in compiler. so we try and make a difference in using these recycling these plastic words. i'm showing the community we are coming from, but it's easy to recycle with the the within the system. after the plastic bags have been clean, been turned into solar backpacks with cute water proof material on the outside. about 20 women i employed for jamila, my and just foundation. they receive about $5.00, but pack pick some of the backpacks. a sold for more than $20.00, but for women and girls can get them for free. more than a 1000 backpacks have already been sold for, donated the backpacks, allow the young woman to be able to dis quickly brings coming and hides

into the schools. so the us to get a better school performance spoke to susan. she also has to do work around the house after school, and she's only allowed to study once it's dark out, which would be impossible without the solar lamp. the next morning on her way to school. so lamp in her backpack is recharged. susan has shown improvement, according to a teacher, will also cause scientific and environmental subjects. she's pleased at the soul,

a backpack is a convincing practical example of plastic recycling the bumps up from with materials. so it does become practical, unreal. but what use a good grades default is to look for to unemployment as so often the case for young women in uganda. but there is another way, goes with tools, offers a solution, a program set up by social inter for now, my younger young woman, can you see vocational training certificates for supposedly typical meal occupations? sure. loan can use his post to receive solar

difficulties the night midnight. please stays on the solar paul is one renewable, and it just, sol, so that's part of a clean, a green of future here in africa, we're all familiar with wind energy and i drew paula to what did you know the ocean's can also so also saw so far oceans cover more than 70 percent of a planet. so we're talking about an almost bound list results here. but technology is not fully developed yet. and there are still some questions. but let's take a look at how it could work. there is a way to turn the oceans and then on limits. it pauses all, you need to something like this plus really warm and cold water. let's see me,

leave me wreck to us. technology is called ocean demo energy conversion show. oh tech. and so, i mean, it takes advantage of the temperature difference between gold and cold water. when you look at the surface of the ocean, the water here can be quite new because it's keeps it up by the sun in tropical waters that can be around 26 degrees celsius. but the deeper you go and everyone who swims in the lake or dives in an ocean experience, is that the kona, the water gets at 1000 meters deep. the temperature which is roughly 4 degrees celsius. and this difference in temperature is what ocean thermal energy conversion utilizes. it's quite simple. you need a heat exchange at the warm surface. what's the heat? so fluid has a low point in point. usually that's ammonium, that fluid evaporates aging is theme, and that's the runs a turbine generating electricity similar to a regular steam. and then this thing gets cooled by the deep sea water back into

a liquid. and the cycle repeats. well, see what i itself doesn't boy like here with this thing, my hands on now basically the sea water, which now heats up the fluids inside. and as it can see, it goes up a and that will say a tom on in there, it was spent. this process can run for 24 hours, 7 days a week, unlike other renewables such as wind or so not. and when you have a great, a temperature difference with water surface water like this one here process can run even quicker and create more energy the wow. 5 that is so quick. the groundwork for this technology was late in 1881 by french physicist zach i've seen dice on top. is student jobs, clothes that actually built the 1st book, unsuccessful, low tech loan in cuba. in 1913 later interesting though tech peak,

when oil prices exploded during the oil crisis in 1918 us president, jimmy caught the signs of law to ensure the production of 10000 megawatts of electricity from tech in the next 2 decades. the problem here is that you need to get that cold, deep sea water up to the surface or on show where the feet exchanges from major limits. in fact, the is that we need a big temperature difference between the surface and the deep sea water. the one surface water is available only around and a tropical equitorial zone. that's crucial because a smaller temperature difference means less power generates it. yes, so that mission is to dress a real problem in getting people to generate sleep baseline. pow wow. this is dan greg. his company's looking to build the biggest outtake platform, to date, a $1.00 megawatt unit and sell to me and print to pay what we have. we take it

because we're pulling this really close to the different thing. well, 520 degrees, little south. the white top, we also have reese plant, please raise and lower the credit ratings. and many of these islands, navy equate to rely on these little generates of power tech would change that older studies estimate that if you disregard practical and financial huddled oats, that could pile the entire uh, wells hypothetically. today estimates for a $100.00 megabyte. tech pond can range from $780000000.00 to $1500000000.00 us dollars. a big unknown is called was quite today. hot plastic pipes, 2 to 3 meters in diameter. a pretty standard before a 100 megawatt pontoons pipes almost 4 times that size and pipes that big haven't

been developed yet. it has proven so tricky that a floating opec near the indian state of tommy and not who did not succeed because of cold water pipe failure. and even if it works, storms can destroy the entire thing. that's what happened to one of the 1st part of plants in 1930 to this on such as he has even driven away companies with more than 40000000000 u. s. dollars in revenue, lockheed martin was set to develop the biggest opec pond dates in china. but drop the project because of the costs. another big question mark is the actual effect on the environment. because you're moving insane amounts of water. we're talking about 4300000000 kilograms of warm water and 2200000000 kilograms of cold water per day. for a small plant, that's about 16000000 best tops on what. so. there are a lot of question marks about attacked the economics, the environmental side effects, the cold water pipe, and today's plants,

i just way too tiny to figure anything of that out. and in the last 10 years, not much. this happened. so until series money is put into it will take probably won't be taking off any time soon with inflation driving up for prices across africa and around the world. mainly is struggling to put food on the table. fresh fruits and vegetables come be especially expensive. so how about growing your own brand cabinet project in jonas bag is showing city as well as how to produce held the food at home. i'm able to turn it into a presence of the tennessee benefits the community. nestled up to the highways offices of downtown johannes, but lies lowering through. but it's no high income neighborhood. in south africa, food prices are used by 14 percent this year, and residents here, a barely scraping by every day. it's hard,

sometimes they don't. and as you can see, the green people i see last time i usually buy the books, big 5 run. last week i go to the, i see the books, it was 75, run the waiting up to 14 shoulder go up to show a little up. so hes managing nowadays, if to cut one way out until the predicament it could be urban agriculture. the victoria yards present in lawrenceville is just one example of what could be possible in john is that this revolved industrial sites. much so piece of mocha. bonnie wants to move to beach urban dwellers to grow and process their own food is beautiful, this is mean it's very good. you can even put it on tv and see when to be in new i t. i love to so much here, john, his book, self proclaimed dream leading. it's the green business college, a police dedicated to inspiring people to get their hands dirty in the soil. and we can live in from it. the good economies, big. so as a college, much as

a cover all those sectors that, that i mentioned was touch with a new food. and then the you fluids. we said at the beginning and the beginning is food for about $75.00. you lose the college offers a 5 day workshop teaching skills to grow organic food, cool kids, and preserve it today. my company's teaching has students to be paid, sharpening on how to pick up, which device will storage. it's done with household staples like vinegar, sugar also. but the green business college also goes beyond plants in cooking on preserves. and we cut part of this training with the business q of an exposure, because we're a business coordinates and do also want them to be and up in us who doesn't go beyond doing this hudson's for themselves. i attended a consult class that told me that you can also have make a garden on the head stuffiness. you cannot see, i don't have space,

they've got these also tires. actually. that's what i learned, that we can actually convey to allow waste into something for dad to south africa can produce enough to feed its population for the 2021 in full. how soon wins hungry? because of the rising costs. making healthy food. affordable was one reason can offend poco, got into agriculture since he graduated from the green business college 4 years ago now runs a small urban farm in the north of johannes. but yeah, the trains musician believes that people in cities like i need to re learn how to grow their own food. on his plots. he regularly teaches young glucose, basic farming principles. i hope to see everyone not competing about how to guide the more, you know, customer take this too big get guidance so that everyone everyone has smaller as well as more than a piece of what we have, you know, and, and then the is this pepsi opportunities that costs, you know,

100 cards of stomach outside does a lot of oil put units. you know, there's so much money here in pull good offers these policies for free today, another local government has come to show how to make self watering planters also for plastic boxes to grow vegetables and herbs at home, valuable green skills and hard times. okay, all right, so with this group plus my id and that would be healthy. and for this, do i after training more than 2000 students, it's success stories such as these that inspire months, the piece of my company to spread her green message. thing for does everything. that's right, that's everybody has to corporate or no corporate name attends or the images pop up to him to provide to people that have to it. and everyone is including the president. each new guardian filters and every garden mean listen much more than

just help people to meet the needs. at the same time that we gain from in skills, boost vital insect on prompted by diversity on air quality in urban areas. while spreading the seats of local empowerment to so a win win for rule, what i'm paying for is just the same point they should, they can make thanks for joining us today. to check out it. go off or go online to find many movies for each of those stories. it's time to say goodbye. i've chris a lens and illegals nigeria to join us a game next week for by the
