hello, this perhaps the greatest leonardo masterpiece and the collection of the louvre. and no, it is not the mona lisa. it is the virgin of the rocks, 2 versions, multiple copies, and a hidden drawing. was there another symbolic meaning to this beautiful lady that perhaps we just don't understand today? search for answers starts july 7th on d, w o . it's time for new edition of a qu, africa brought to you by eggs in uganda, dw, from gemini, and channels television. the n i g area by name is priscilla ebbs common to you

from nigeria. and i am sandra trina video here in com. paula: we are delighted to have you with us today. as always, we have a great lineup of entrusting reports on ways to better protect the environment. so here is a quick look at some of the topics. awe inspiring, the next generation of conservationists in one depth. let me be as revolting drop population and why up to position is creating marine pollution if put to go we start the shore in render with a topic that is relevant to many african countries. now how do you explain to the future generations that he ease a better to protect the animals other than hunt them all down? let his stuff as they read a long tradition of hunting in random. he is more in this story

with me. what kind of monkeys i lease, what habitat did they need and what are the threats the faces on these youths belong to an environmental club? we teaches them about wild animals in the hopes they'll help protect species diversity and promote peaceful coexistence between people and their fellow creatures. the initiatives, founder and head ash machine, we expect great things from the students. you have to protect the environment surrounding you. but as the, when you find the in any more in the community, you can advocate for it. don't keep the animals don't this tub or cut the trees. always think that when you are protecting the environment, trees, animals, you are protecting your sales of well about immune good, national hon. that is a treasure true for biological diversity. the 1068 plant species have been counted

here and many of those grasses and cheese and found in any of the forests or parks in rwanda. but is not just the greenery that's unique. the park is home to $322.00 species of birds and making it a great spot for bird watching twice a month in many shim way. and his group explored the national park, hoping to encounter some of its 75 species of domestic mammals. like chimpanzees or rare owl faced monkeys, but at school they learn more about what they've seen. this project is part of marijuana and government initiative that will allow you to live in the you guys. you the members over the middle of the glove were the feet of this country, which means that teaching you educating you in the having you taking that stick.

tulsa, that did that pulled me over to feature the pupils take the emission seriously. the a c, me responsibility for the environment by preserving its plants and animals. gumbo, co amended, and these environmental clubs is to be right on the front lines for environmental protection. it's unacceptable for people who have their barbara to be left to their own devices. ahmad, they must be shown the right way of reporter to the authorities if they refuse to change your attitude arca. although that coin using the chief with more than $400.00 people per square kilometer rwanda's population density is very high. so folks keep encroaching on nature with disastrous results while species diversity, the partial settlement of a could gara, national park has led to the disappearance of many lions and rhinos. so the

government wants to sensitize people to their environment. and not just school kids under foe who cannot avoid invoking those would never go to school from the to avoid involving those who stopped as kudos to attend to a jetta, tennessee, rosalie, to go put it in to this fight. so on weekends, school groups visit villages to spread their message. careful, wild animals don't set traps or chopped down trees. often they propose a treat villages can receive farm animals in exchange for given upon tim. because like young marie viani ramirez, many here will once i hope chest arrive, when i get them on i used to hunt antelope and eat them with my family home with birth through this awareness sunday opportunities offered to awesome. i've stopped coaching since we've been given domestic animals this no need to hunt in the park

by taking the youth's move on to the next village. more than 60 people in the area around noon game. national park have given up poaching some now res life stock instead. i'm others i employed by the project than work with cheese, who's lease i used in traditional medicine, and then how to build terraces to stop the rouge. the ridges outlook is improving, says ons, the machine we partly thinks to the environmental clubs. there is a very huge change in terms of our mindset. i only knew it and they can see that many people now have understood, understood white as in political sov. just 7 of you and has 30 districts take part in the environmental club project. but that could soon change

youths make up some 2 thirds of the country's population. so their help is keen to preserve his species diversity. honda what a terrific program. let us all the passion for those lessons learned at a very tender age last a lifetime. but you don't have to jane a green club to help the environment. we, as individuals, can also make valuable contributions. a lot on our own. here is a basics doing given. i charles in gaithersburg committee has single handedly grown his own forest. the engineer own 6 acres of land in kenya. 10 years ago he started planting indigenous trees. each time he went on a business trip, he'd bring back native species. when they come up with it and it came up, goes not loving here. they are nowhere else. there was no,

no trees in the moon when the rich dish on came up, the wheels now started emanating from down there valley. and then when you compare now this area we've been maybeth. there's a lot of edition here. his forest is now a place where he leaves russell birds, sing, and insects hum. he started producing medicinal plants and honey bananas, patch, and fruits and yams flourish among the trees. the local community also profit from the arboretum is new. biodiversity in, in the local language, with the agro forestry coming in awe of indigenous cheese. we are noticing some changes such that the soil is changing from degraded from degraded, eroded land to now more improved with more humorous. and it is supporting more

life the trees even brought back the water charles and gave a committee has shown that nature can revive when given a little helping hand and tell about you. if you are also doing your bits, tell us about is visit our website. both send us the tweets hash tag doing your best we share your stories. when you think of endangered species in africa, animals like the rhinos, the elephants on the punk lanes quickly come to mind. but did you know that jim ross of also been on the read list a via was fishes for several years. it's true scientists from an angel bays denobia. i've been studying giraffe populations very closely. and the good news is

they say they have reasons to be cautiously optimistic. most people are familiar with giraffes, but far less is known about them than many realize what certain is that they are the world's tallest land, animals which enables them to reach leaves high on trees in the african savannah. what's less anon, is that you rubs are incredibly fast in short, best they can run up to 60 kilometers in our beyond that there are still many unanswered questions about them. what are the different species? how many giraffes currently leave in the wild? in namibia biologist lackland mac features in jordan, michelle more want to learn more, the photograph every year of the sea, so they can be identified later at a female, right? 8573. of the visual studies like these have concluded that they are currently only

$117000.00 euros in africa. by comparison, we are nearly 4 times as many elephants. if you think about some like an african elephant, there are no, you know, i ran at 400000 mark, i believe individual. so if you think that compared to 170000 individuals, and it's pretty incredible for such a, a large, a browser spaces that is called a one of the, the most iconic spaces in africa. really. there's been very little work done on them. i suppose the priority in the past has been some of the more sexier species like elephant and lion and drop of sort of gone under the radar. and i think because they are quite wide spread throughout africa, you feel like you see them everywhere. but that is deceptive. climate change in humans clearing land for settlements in agriculture has led to a substantial loss of happy 10th 40 wraps in the past that he is the population of these graceful animals. his sank by about a 3rd waste in rivers also threatens their drinking water. when tories numbers

dropped you to the coffee pandemic, these guys started picking up the trash instead, which will benefit the drugs in the long tim, protecting these animals has a long history in the media. if i can tell you more little bit about the bushman, the they were not killing drop at all, even during their handing activities. they were not targeted to ross because they thought it was a policy anymore. and they realized it killing a giraffe. you are cutting the communication between yourself and ancestors. this was once considered a sacred sport. 3000 year old cave drawings prove how important giraffes where to the people living here they were regarded is bring us off life. oh, we believe in europe that the mag ex extent they are neg, touch their clout and make it dream. so good. rain is

a good. i have year for them. wild you wraps in western and central africa as to under threat. they are numbers in namibia, in its neighboring countries, are actually increasing rising from 30000 to almost 50000. that's largely because they are better protected here in national parks. this is done vision game reserve located near namibia capitol hill dog. today, kids from the children's home are hoping to get the 1st glimpse of a real giraffe, a little a drug skull like this one is very heavy. the animals sometimes use the borne, your projections, cold, or seconds in combat with other animals was like old old standing next to a lead bond. keep the kids an interesting sense of proportion are you are now on my leg drives. i love the colors and i like it looked like i am dull,

very strong. so draft kicks are very powerful. that's how they defend themselves from pre did us. for example, lion, for the can kick elaine, the children won't have an easy time sporting the animals to day g raft. i shy. this turtle on the other hand, wasn't too hard to catch. you don't put your fingers next to the mouth. it's hoped that if children live above the animals in the region, there will be more likely to fight to protect them in the future and doesn't get in group of kids. and when they see animals, for example, if you have continued an elephant or defeat, oh, i'd be standard, tell you it's a horse in that's surprising because we have foaming the wildlife in the country. that's why we think that if anything, my mental education, and that this program is actually making a change in difficult life, drops prefer leaves from bush's in trees or long river causes

a cassia trees are among their favorites. biology is like landmark feature. see that as a result, they don't compete with lifestyle for food making conflicts with farmers really. so far, the scientists have counted 450 giraffes here in northern namibia, and they are doing all they can to make sure these elegant creatures survive. val to europe, to help people, we must also help leisure because if we are to endure its bounty, the future would need to treat it would respect the oceans once teamed with life. what over fishing and pollution of taking the at all? so what if we went back to doing some things the way our ancestors did when night falls in southern portugal, it's time from our reseal no get out to head out to see. the fisherman is heading for his fishing grounds to north miles off the coast of villa vale to santo antonio

. there he will catch octopus, like many here in the alcove. maybe i grandmother grandfather and father fisher octopus as well. and my brothers to them, if you need to have it in your blood, is a tough profession on the ocean, takes everything out of you. i'm not, i'm luda. strong winds and high waves make the work difficult tonight. the 44 year old fisherman is committed to the traditional way of catching octopus. he sings clay pots into the sea with a rope, and uses a winch to lift the pots out of the water. in some that will be an octopus hiding. l like his way of fishing is just farrah. the octopus goes into the clay pot to sleep and can swim out at any time in a tree straps. on the other hand, a just trice going up. i'm but fish traps are being used more and more often.

maurice, you believe this is one of the reasons why there are fewer and fewer octopus is in the region. yeah, that yeah, me bother afforded years ago. there were no traps. just clay pots, not a lot. my father tells me that in those days they will occupy all year round to day, more and more clay ponies and being replaced with traps. and some nights i hardly catch anything. he then, long term with santa lucia is the alcoves, octopus fishing up. and the fisherman, though all the fishing methods inside out george kane olivera, that altered for traps with bite inside 57 year old says is more efficient and convenient because the traps can also be retrieved during the day all winter. but it, it, the octopus goes in here and can't get out in one blade mill that a by level until 2000. and i also worked with clay pods. then i switched to fish traps because it for less hard work. fishing is easier. him and you just catch more

of them yet he never. my 20 that talked to plus fishing is changing the remote traps and more plastic. the traditional clay pots are being replaced with plastic containers. now, what i found that angle is a marine biologist al. gov university. she's worried about this development and points out that the oceans are already full of micro particles, which tries to promote sustainability around 27 percent of all plastic that is in the fi, come from last year's or are efficient devices. so there's, there's, there's a huge problem there with those, this bottom, the other fishing gears that get lost and are made of plastic material. married to goes out fishing again the next night. he has to hurry up to get the last octopi

before they wake up. and swim out of the containers. and he also once again asked to repair a roof, it's been cut deliberately. i thought all that the road is broken because another fisherman cuts it. not a lot of dogs. yeah. they don't respect my space. i occupy a large area with my clay pots and that admire the others. yeah, i don't think there was a lot of competition and it's tough for him on the markets in that see. but marty to wants to keep to his old methods. even if that means he has to stay out until the early morning hours and thought about that is that of i, if you work hard and you're skillful, you can earn decent money in a month and then you had to put up with a cold and the bad weather, the info, out of that part of it, you can make a pretty good living. that'll have authority. he believes that his method is more

sustainable and hopes that it will one day be required in the alcove. so the sea is protected from portugal, we had further down the atlantic coast to senegal. here is something you may not know peanuts are considered the backbone of the senegalese economy and more than 90 percent of the harvest, is it sporty to china? peanuts onion, vicious and versatile, and even come in their own packaging like march either packaging peanut shells aren't meant to be eaten, but they can be put to good use as we'll see in our next report. oh, good. these buttons, cell batteries may not look very special until you know the raw material used to make them at this lab and dac, ours shake until

d up university hospital peanut shells about thoughtful milestone to see view transforming this type of biomass into advanced materials is a new field of research says, 2nd, well, rush us, the scientific community has been working on a for 2 or 3 years just to fix on the ultimate and we were the 1st to initiate this kind of work here in africa. all right, you see on lovely boss, alma peanut shells are plentiful, and synagogue peanuts are one of the countries for most important exports. more than 60 percent of the rural population grows the popular and energy rich leg. yeah . but this year, a low harvest of around $1600000.00 tons is expected due to poor rainfall. until now, the shells have simply been thrown away or burned pure ways that says professor, can gum. he regularly buys his raw materials at the t lane, central market in jakarta avenue and explains to the trader that he makes batteries

from michelle's getting them bring it analyze. hm, thank you. whoa. whoa, i'd never heard of that. i mean, you're good. it seems every day you wake up and there's more technology, more developments. but i'm happy to see it happening on both on the la martha and that the peanut shells help blue light. i wonder lip loki let me get a music for more than 2 years by the d up and gum has been researching the conversion of bio mass into energy with a group of 15 students. so, oh, well, it's a complicated electrochemical process. first, the shelves are ground into powder, and mixed with water. oh, la la st. on good, a thought. the whole thing. so for a period of time like this, i don't know, i won't tell you how long of it, because that's one of the crucial parameters. while applicant was optimal, then we filter the mixture and the result is this liquid whose it as opposed to the lumbering. once we add some more ingredients, we can use it to create the positive charge of the battery was achieved

a lot of disclosed. the researchers take advantage of the high carbon content of the shells and extract a zinc oxide from them bonded to raja global when the liquid is radiated with sunlight at high temperatures. the zinc oxide evaporates and is converted into metallic zinc, which in turn can store energy these are environmentally friendly batteries that have the same potential as conventional lithium ion batteries for example. but without the disadvantages. that's because lithium ion batteries contain among other things, cobalt which is often mind by children in dangerous minds and the congo. in addition, reserves of lithium and cobalt are limited. so the plus points are that the peanut battery is produced without cobalt, easier to dispose of cheaper to produce. producing these environmentally friendly batteries would be of great help to synagogue. since 40 percent of rural households

have no connection to the state power grid, they rely on batteries or alternative energy sources like solar or simply don't have access to any form of energy. there is a huge gap in energy supply. this, according to this environmental analyst role as a basic up a pasco full. he fulfilled this gal la body. i think we have to move toward the development of energy sources like bio mass, lebeau mos. in his e. l y, a mass energy can be an answer today, because senegal is a major producer of peanuts with a huge supply of peanut shells, my and not i'm on can, will look that as it gall, we're liaison for areas like cause a mass which has a significant amount of bio mass amplify the development of this energy source. it will allow us to close a large part of the existing gap. don't go permit that as of a in gun party undergrad. think up a key exist or what we'll see later in preliminary trials. the researchers were

able to power remote controls or cell phones with their bio batteries, but their product isn't market ready yet. liz's, you are, we now need to further optimize all the processes in the lab to get all the parameters fully under control. it was the so that the system works properly, it total told us off and then it will be ready for market encore, me dollar machine. the research team and decker is now sure their batteries work. however, further research and money is needed before they can upscale production milligrams so that people and synagogue can actually use peanut power batteries, just acquisition and that rounds of another show park to information innovation and of course ideas i hope you found it is firing. so thank you for watching it is now a good buy for me, sandra, queen of you here in complex uganda. so long sandra. see you next. i before i sign

of just a reminder of a you can always check in with us any time on our social media channels wishing you a good week ahead. bye for now for me, chris a lives in nigeria. ah . a. a . a ah. with

the secret more between iran on the one side and on the other israel and the united states. why does a do ever seem to end for over 40 years old diplomatic efforts have failed. i believe there has never been any real dialogue in the 2nd part of our documentary,

the long 15 minutes on d w. i more precise than you. i'm stronger and move faster, more efficient and cheaper. your favorite products could be made for less money. eli musk, thanks our place to you. one day i see that you're not convinced. let's talk about it. made in 90 minutes on d. w. o. they will stay with love and banning thing

away from them, but i didn't have to was my own god. and everyone with later holes and everything else, getting you ready to meet the german and i me right, just do it on d. w. i is the end of the pandemic in site. we show what it could look like. return to normal. and we visit those who are finding it difficult to success in our weekly coven 19 special. every thursday on d. w. or c. asia and artic lovers guided by vibrating asian cities. 5 a local artist. ah, in the unique experience of their craft,

i joined us for exclusive master classes with this week on dw ah, ah, this is dw news live from berlin, moore, washington tax and eastern ukraine. the governor of hon says everything that can bird is already on fire as russian missiles, rain down ukraine is still waiting for more heavy weapons from the west. a diplomatic crisis escalates between russia and move away.
