oh, ready knows. welcome to tech told me about hackers and paralyzed me to your societies computers than elsewhere. you and governments that go crazy for your data. we explain how these technologies work, how they can only go wilson for. and that's how they can also go terribly watch it, no need to ah, we all know that it is important to make a good impression. and the clothes you choose say a lot about what sort of passing you are. i am under tween of you and today on

equal africa, we're going to be looking at a topic that ease a very close to my heart fashion. and to mine, to sandra, as he can see, thought we've been looking into what happens to all the youth clothes, especially the thousands of thousands of ship fashion that are thrown away each week. i am chris, the lamps. add this is what else we've got for you to day of the show. ah, the read this called re uh, the miracle plans. hemp us if facet al raw material. a surprising solution to the waste from to the shells. olive oil harvest and the high tech ways in which south oper guys protecting hundreds of shaft species. recycling clothes is big business as more people get used to change in the luc often. one problem with

these cheap fast fashion is that it is often so poorly made that it cannot be re used. what text are traders and garner, but millions of old clothes imported from milly. western countries are often more rocks than reaches. almost half gets thrown away, which is clog in our land feeds. beeches and the ocean were met. some people were finding ways to stop that happening. these fashions from the canadian capital, a young, urban and above all mega hit. you can look good and take responsibility exam. so that's the message from across. young designers like elisha banfield and video behind the nonprofit label of the revival. yet iraq, papa and crime may not darzy poison or our design is just our tool,

our tool to m and ditch every individual. you know, every global citizen to, to wake up and see and question everything about the crosby way or things w coins human. ah, at this studio in a crop, the 2 men mix different materials and pre loved governments to create something, need used clothes that arrived and gone by the ton from the u. s. europe and asia are a source of inspiration. as we all know, ah, i'm much years years including on, on by to credible most of them. and then they have a very negative impact on the environment when it's being disposed. so we are trying to deconstruct the idea off what waste really means when he comes to textile when he comes to fashion. and this is where the men from the revival source,

their materials come until the biggest market for 2nd hand clothing in ghana and across west africa. here some $30000.00 trade is by source and re so around $40000.00 tons of clothing each year. i'm going more than 15000000 items change hands each week though due to their poor quality. roughly half of them end up in the trash. i know we get to london was day time, hawaii, the curio, was that canada was and we get a grease. we get avery gibbs b a is not all that good. hey, so you open, it's an o d u garak. that's given rise to flourishing up cycling business income tomato, where many text i'll mention, still try to find, take his with another quantity weighs some local initiatives, add a dash of color to faded fabrics to attempt to potential bias. job in

tennis workshops. old clothes are used to make new ones as cheap clothing becomes more available around the globe. the mountains of 2nd hand textiles keep growing in ghana. what starts as fast fashion soon winds up here, often strewn on the beaches and in the sea. and because more synthetic 5 is being used in garments the materials with their chemical residues may linger here for centuries. it's a threat that worries fashion activist and environmental research a harriet, an a jumping i am concerned about the environment. i'm concerned about. everybody within their 2nd hand business supply chain because fast washing and 2nd hand. good honey hunt. so yeah, i guess and r a is polluted apparently. so these are just things that we shoe

stopping a lot more attention to and start consciously developing business modules that actually puts pressure less pressure on them about that. she says we really need to get to the root of the problem. donna's quality controls for 2nd hand clothing impulse or an urgent need of improvement. not every one sees cancer, mental as m. m a half for the sourcing of raw material. so i few holding their bronze. different washing bronze are countable in looking at it. looking at the bigger picture of how i mean their regulations could actually contribute to national so sure, economic development to date in ghana it's been mainly activists or artists like michael god, who's given much thought to how to use the clothing waste that's already in the country. i thought is a b,

she's around dark and people are nearby. and so i took it upon myself to also buy them to create my pieces natalie for, for their beauty amazon. so m greeting awareness for day and barrow meant course, you saw tom t o m there martinez that you finding nearby in their beaches, us waste. and they took our got us too. so i muscle and greeting awareness for and people to be eco friendly. sheep close can even be transformed into art. it's one of the creative ways of dealing with the waste, from fast fashion and courts. at least biodegradable fabrics such as cotton and wool will eventually decompose. but these days, the most used fabric is polyester,

which hangs around us waste ali's heart to recycle. you can burn it, which is not good or scientist in england are hoping you can find natural chemical compounds that can eat up the plaster clothing and turn it into something reusable . again. in this laboratory in the british coastal city of portsmouth, researchers are deep freezing articles of clothing. the experiments with liquid nitrogen and polyester shirts are being conducted to deal with an ever worsening problem. obviously, with growing population as a growing demand for textiles. i'm. we have a, a burgeoning waste problem with those textiles when they reach their end of life. so we, we very rapidly need a solutions to, to deal with the recycling issues. world wide consumers are turning to fast fashion clothes, manufactured at low cost and with high turnover. a cherished material polyester,

this clothing fiber accounts for 60 percent of what we, where it's a fast trying, durable and above all cheap fabric. making it very popular in the fast moving clothing industry. but fast fashion clothes are discarded by the tongue in landfills like this one in kenya and polyester, a synthetic fiber is practically impossible to recycle. but the scientists and portsmouth are harnessing the power of enzymes. so we have a engineer enzymes are to be capable of tackling the polyester in a single use plastic bottles such as this one here. and what we want to do is to see whether the enzymes that can break down these plastic bottles are also able to break down the polyester in fabrics such as this one's frozen in liquid nitrogen. the material is ground into tiny bits.

next those particles are placed in a bio reactor with are mixed with the enzymes play. we can think of an enzyme as like almost like power says. so when we take our plastics, that just like a very long string of different molecules, and then we use our enzymes to cut that string and specific places. so when we do that at the end of the reaction, we have like the soup of different parts of the plastic, which we can then swasap right often that different things. and then we can react sized to either make a new plastic, or they can be used in other chemical industries. the researchers in portsmouth have already identified more than 70 enzymes that can break down polyester. a development that will hopefully lead to more sustainability in the clothing industry.

let's move now to a rural material that is used in many different ways and goes by many names. hamp and color bees are the best noun. we are talking about a plant which has been used any innocent form for hundreds of years. for textiles. pepper may be seen energy and oil, but the rise of the drug trade caused tempt to be demonized and criminalized, but deuced at you. these a miracle plant is making a comeback, and that has also its benefits for the environment caused by many names, pen cannabis, marijuana we ganja. and just as diverse as names are, it's uses. we made our take styles, paper, medicine, energy, oil, all the hump. until we started demonizing and criminalizing,

we've hammered it down into eyes, humanity's head that this is an illegal, and massively bad plan. hem cultivation started $12000.00 tuesday, going china. and from there, human stupidity, a rule that sailors used highly durable, hemp for de ropes and sales. so they took the seats with them everywhere because of the root. hemp was the 2nd most used material on the ships. it's flowers had been used as medicine for thousands of years as well as in spiritual practices or just simply for pleasure. but then came to dark ages for cannabis. new technologies were invented for cuttin, which boosted supplies of fiber. trees replaced hamp as the paper search. and later, sales and rover made with petroleum based synthetics. now the makeup plant is making a comeback. scientists as slowly discovering that its uses can go

valid beyond that you'd have known so far and could help us clean up a lot of industries. a big one is construction. that building and housing industry produces almost 40 percent off, all carbon dioxide emissions. but that might have changed at hemp is already in use as an installation metro. but now, more and more sustainable construction companies use temp create to build walls and floors to like this 12 floor building made with 10 clayton's south africa hem crate is basically a mixture of hampshire and line line, petrified the hemp site 7. the great or break it is light, but strong. it is breathable. site regulates moisture and temperature better. that means no energy builds normal and basically man toxic environment. it is fire resistant and due to flexibility can withstand major it's information properties

and also the checks. it says heat sound and humidity insulation, and after its lifetime, hem creed can be reused as fertilizer, as it is totally organic. ah, attempted most not on to produce less carbon then concrete lungs. they're actually carbon negative. that means hem could stores more c o 2 than it requires to make and transport. that is the, the, him carbon storage capacity fiber insulation stores on the net base, more than 50 kilograms of carbon dioxide per cubic meter of insulation. for your reference, the production of glass will or roku installation emits over 250 kilograms of carbon dioxide. but sickle is in most countries construction regulations are very strict and introducing a new construction material can take years of testing and bureaucracy. and that at

the beginning of central, in many countries, we need to give it a new chance and stop putting all these regulations on him. we need to free this up entirely for the industries to really move forward. can also help reduce deforestation until the late 900 tree must paper. it was made of hemp, early bibles, and even the drafts of the u. s. declaration of independence are written on hemp. but to day paper is made from trees. and it is one of the biggest drivers of deforestation every year via the forests. the size of portugal, 15 percent of all trees be chopped down, are used to make paper. global demand is expected at least doubled. and in some cases, almost triple violet, losing our forests. some companies are more willing to reintroduce hamp into their paper. production decks tell, industry is a little bit to holy grail, to geminus league for her,

for any fiber. it's all said champion peloton. because cutten needs a lot of toxic pesticides and water take care of him, can produce 2 and a half times more fiber than a hector of cut. and it can grow up to 5 meters within just 3 to 5 months. hemp fiber is not on the better for the environment, but it's strong fibers also make longer lasting, textile, less water, less fertilizer, less than did not pesticides, but stronger and lusting fibers. but there is a catch. if you want to be successful implementing m fiber into the textile industry, we have to modify him fiber to existing text field machinery because all the way around not going to happen because the investments to do so. i used to hi, thanks to the patients. the textile industry has been facing companies and researchers have been trying to find out, tentative now using enzymes or mechanical processes. they have found environmental

labor to cut the knives and integrate hemp fibers into their existing products. but this is still in the early stages and it will take some time until the industry agrees on the best way to get the nice to handle. this is the 1st problem. hemp is facing in other industries to lack of standard matters because of missing research and development for decades. regulations are still confusing and they change from country to country. these differences plus the fact that my wife killed a controlled substance care of the investor, but against all odds, global industrial, hemp demand was calculated. they had a $4000000000.00 market value to any to anyone. and he's expected to reach almost $17000000000.00 by 2030 that's something to look out for. indeed. now to another interesting plant, the only tree it flourishes in tunisia and housemaid, the north african country,

the largest producer only oil, said the rope unions. but the bountiful harvest produces a lot of organic list that has not proven very useful. and to now find out in this weeks doing gibbet. ah, yeah. the olive harvest takes place during the cold season. winter's in northern tenicia can be brutal. temperatures can drop down to freeze in the country needs fuel for heating, but even if there are hardly any forest. there are countless olive groups. tunisia is one of the biggest olive oil producers in the world. the extraction process creates a lot of left of a promise or, or live poke that gave yes, seen can give me an idea why not use the pump for heat intervening. did wanna get garcia. i had an idea in my head, and i have kept since my childhood revisited because i visited the oil mills with my father flexion during the extraction of william oil thinking. yeah,

i saw there also said the bowman's talk was used for heat central clip off a cookie. it was on so on while edge, and then it clicked. so sit there and break it, made for olive promise. yes, it is a jew engineer who founded the start of buying in 2020. it now produces $150.00 tons of brick. it's every year. the good news is that the eliminate the need for locking because the heating value is 3 times higher than conventional water, brick it and has lower carbon dioxide emissions. pizzeria is i using them in the album because of the good burning properties and hefty been amo, once a hammer has nothing but good things to say. and so money feet are, they are magnificent upon your order, the smell lovely and also provide very good t tree one. china can only freak the success story is affecting locations well

beyond tenicia in the south of france. esteem treme has been powered by a thin can the fees olive brick. ah, and how about you? if you are also doing your best, tell us about visit our website. send us a two's hash tag doing your bit. ah, we share your stories. here's some help because coastline stretches far more than 3000 kilometers and the waters around it a home to an abundance of marine life, including hundreds of shock species. now these practices are often vilified and feared, but they have rolled in the ocean ecosystems now recognised as extremely important . south africa has been a trail blazer in shock conservation. so let's take

a deeper dive into the innovative tools used to study and also protect these often endangered species. the migrating blue sharks are frequent visitors to the coast of south africa, pacified shy shops and gully shops, a native to it's called forest. these brown seaweeds are home to more than 200 shock species. ah, shock expert ryan daily regularly monitor their activity to conserve shocks. we need to know where they go, where they've been, tom. so we are tagging the chart to figure out where they go and identify critical habitat for them so that we can improve protection for these critical areas. he and his team fit the shots with acoustic transmitters, so they can track them a procedure. the shocks barely noticed once they've been tagged,

the transmitter emit an ultrasonic pulse for 6 years in the last couple years, have tagged over a 100 shocks, representing about 10 or 12 different species. many of the shocks aw, endangered. and we hope to find out more about the way they go differently the multiple years. we have identified critical areas for them. over $150.00 receivers are moved along the sea badge to detect the signals from the tag shocks. whenever one of them swims by the receiver records, the id number, the signal ranges up to one kilometer. the acoustic receivers are regularly brought onto dry land, so the data they have logged can be evaluated. we

have to work with a big network of collaborators to share data on the receivers. so all of the day we collect on the receiving, it said within a network, and then we able to figure out the way the trucks have been where they've been in the town so that we can prioritize the conservation the program can only work so long as there's broad support for shock conservation effort from an early age humans are afraid of these ocean printers. shocked populations can only survive if public attitudes to them change, and that requires raising awareness. by changing the mindset, i believe that i am changing the world one step at a time, one kid at a time for me 5, a group of 40 learners and i'm changing the mind of one child, even if it's going to the families and teaching them why shocks i important really making such

a big deal in the media tends to report on shocks mainly when they have been taxed on human at the shock education cent in cape town at children can learn about the valuable role they play in marine ecosystems and get up close with shock, eggs and even teeth. so secretary love to pick those on how they actually love and that they're not actually things that we actually endangered by polluting and by caching conservationists have also equipped an underwater camera with bait. so they can also observe smaller, shy, a sharks that look in the camp forest, off the coastline it lose the amount of hiding allowing the researches to gain useful insights into ocean biodiversity. the collected data is analyzed using a program the team developed to help them assess their finding.

we've taken some open source machine learning software and trained it on hundreds of images and sharks and fish and all the species that we come across here in false de so that we can use it for detecting the species in videos in the future. their research has already proved highly constructive. there is already more public acceptance of shock, conservation and conservation areas. now make up 5 percent of south africa's oceans . environmentalists would like to see that area increase further in order to protect marine ecosystems. well, it's time to return to dry land. i hope you liked the show and held some key takeaways . my name is sandra to no video. thank you. bye from counselor here in uganda. and

the bye bye also from me chris, the loans in oakland state nigeria would love to hear from you on our social media platform. if you have any concept or ideas to ship, take care and see you next week. ah ah ah do ha ah ah

ah ah ah, [000:00:00;00] with who was making the headlines and what's behind them. dw news africa, the show that was the issue shaping the continent. life is slowly getting back to
