♪ host: welcome to "global 3 300" ththis week we f find out why ya mother in south africa started a business manufacturing wheelchairs. in cambodia, many turtle species end up sold at food markets. conservationists are trying to save them. but first to china, where the city of shenzhen continues to be developed, driving many residents from their homes. one consequence of china's economic growth has been a mass exodus from rural areas.

between 2008 and 2018 alone, some 200 million chinese moved from the countyside to the fast-growing mega-cities. urbanization is transforming the face of the country. in the m mid-1980's, shehenzhes a sleepy fishingown.n. todaday it's aigigh-tech h hubh a pupulationf mimillions. the chinese government wants shenzhen's growth to continue unhampered. and it's determined not to let protests in neighboring hong kong get in the way of its plans. reporter: he has no time to the e reets of shenzhen. mrhe has to act t fast.hrough hihis old place e is being demolished.. mr. thanh: i need to find a r.r. i ve t to mo housese. hihireporter: why?is being mr. thanh: the houses here are beintorn down.i need ae. rerthe family possessions.htes itit's abo to o starrainining.al

disabilities. millions of them rely on wheelchairs. in industrialilized nations,s,% of peoplple who needed a wheelr have one. in emerging nations, the figure is less than 10%. that prevents them from fully participating in everyday life. in 2018, 600,000 children with disabilities in south africa didn't go to school. that will reduce their chances of finding gainful employment when they're older, and increase the likelihood that they'll face discrimination. reporter: when the sun rises over cape town, south africa, pepeople are already hard d atk in a neaearby suburb. the e shonaquip company makes wheelchairs, and many of the people who work here are also wheelchair users. for the owner, shona mcdonald, inclusion is very important.

shona: morning, ralph. how are you? ralph: i'm good. yourself? shona: good, good. everything o ok at home? ralph: everything is fine. shona: good. reporter: she developed heher original wheelchaiair model in 1982. shona: i started building equipment for my daughter, who was born with severe disabilities. and there was absolutely nothing availablblfor her. i was given a cardboard seat in a baby pram. and i thought, "this is not going to work for us." reporter: shona mcdonald wanted her daughter shelly to be mobile and to be able to take part in daily life. she developed her first wheelchair for children a few weeks after her daughthter was born. over the years, she's turned it into a business that employs dozens of people.. each wheelchair is individually fitted. shona: just like you would never teeth or -- you would never go

and just go and buy a whwheelchair. it has to be prescribed for you. you have to be assessed, prescribed, fitted, and followed up regularly. because if you don't get the right type of wheelchair, you can develop serious life-threatening secondary health complications, which make the whole point of having a wheelchair invalid. reporter: the tires on her models are especially robust. that makes it easier to use them on uneven ground. shona: i remember writing like a little thank you card to the engineerer who helped with the welding and building this chair for me. and i drew on ththe front covr shelley's face, but with wings. and i said in the card, "this is not just wheels, this is wings. she is going to fly." and i think that was, for me, something that's really been an underlying passion. i want t to see kids f fly, i t them to succeed and achieve their dreams.

reporter: she spends a lot of time on the roroad, visiting fafamilies, organizations,s, d facilities. promoting inclusion for people with disabilities is her calling. today she's going to elim, a small town on the western cape. elim is home to a residential facility f for children n with physysic andnd developmemental disabilities. many of these children have special needs that their families couldn't provide for at home.. shonaquip has a dedicated team thatat provides advice and training to these facilities. danika: we have to look at mobility barriers, we e have o look at social barriers, at educating communitieies, at givg parents places of support, but also tools for empowerment. of knowing their rigights to ak questions to medical professionals. of knowing the rights of their children to be included.

reporter: stretching and gentle exercises for the carers is also part of the routine. their work is very strenuous. physiotherapists provide training on how to assist the children. shona: if you are not sitting correctly, you can choke and aspirate. and that causes pneumonia and secondary health problems. so, the more we can improve the everyday seating of the child, the better their long-term health is, the better their function is, and the happier they are. reporter: by some estimates, a million children in south africa have a disability. their happiness, inclusion, and well-being is shown in mcdonald's life's work. shona: i don't know if i'll ever really achieve what i dream of

as the ideal solution. but what i am really determined to do is to shift people's perceptions and ununderstandingf disability. from poverty and pity and charity and exclusion, to one of welcoming inclusion. rereporter: shona mcdonald has received numerous awards for her work, and has become known as an inclusion advocate around the world. host: for more stories of women who are taking their lives int their own n hands, standnding ur theirighghts, d inspspiring otothers, visit our facebobook channel, dw women. dw women - -- giving a voice o the women of our world. >> i am a global teen.

saeed: my name is saeed yassen. i am 15 years old. i live i in amman, that's the citadel of jordan. i usually play video games. but sometimes i play soccer with my f friend. and my favorite team is real madrid when r real madrid w wins. am afraid of the heights in ththe mounins.s. when i step up in the height of the mountain and look to the ground i f feel very, very afrai persallyly, i n't lolovet.

my favorite class is english, math, science. but arabic, i hate it very much. i think our life now, it's better than our grandparents'. because the transport in the past was very difficult. now we have planes, busses, cars, and ains, very fast trains, th m make usravevel fastly and very quick. i think the biggest global problem is the poor. i think because in the country they have rich and poor, and that is not equal. all people have to be equal and

have our own money. host: : now our series "global ideas," we meet some endangered tropical species in cambodia. our rereporter lea albrecht visited the phnom kulen national park, where conservationists are trying to protect these reptiles from extinction. mao: this one is more heavy, but this one is more strong. you can see the legs. they always want to go. when i found the elongated tortoise babies after they were hatched, i wasas really happy. they were waving their legs.

i was so hapappy that we h had tortoisese babies. reporter: mao tea and the tortoise babies live at the angkor center for conservation of biodiversity, or accb, in northwestern cambodia. mao is a caretaker here, and starts work at 7:00 every morning with a quick walk to make sure that everything's in order. 79 elongated tortoises hatched here three months ago. today they're going to be weighed and measured. >> 33 grams in three months. so, he's growing well. reporter: the toolbox contains nail polish in all colors of t e rainbow. the caretatakers paint the shes of the young tortoises to help identify where in the conservation center they're being kept. the tortoises live in special enclosures that are open to the

sky, but with nets to help prevent them from predators. that's essential to their survival. not long ago, elongated tortoises were upgraded to critically endangered on the international union for conservation of nature red list. michael meyerhoff is the accb's director. he came here from germany more than five years ago to work on animal conservation projects, especially ones involving birds and turtles. michael: there are about 360 different t species of turtle, including the land tortoises. what many people don't realize is that when the nexext red lit is published, about 6060% of al turtleworldwidide ll listed as threatened, dadangered, critically endangered. there's a worldwide turtlele crcrisis right n now, and camba and asasia in geneneral are no exception.

reporter: elongated tortoises are rarely sold in local markets anymore. only one of the 14 turtle species in cambodia is not endangered. turtles are eaten in cambodia, and used in traditional medicine. live turtles are also sold as pets. in cambodia, turtles and tortoises are believed to bring good fortune. releasing one near a temple is believeved to bring g a long l. birds are believed to carry away any bad karma. catching animals and then selling them so they can be released is a big business, even though it's illegal. sokoun: when we have turtles here, they're no longer bought as food. they're bought to be released at temples, or in lakes and jungles. otherwise they would end up in cooking pots. the small ones are for soup, while the big ones are for steam cooking. reporter: two turtles sell here for the equivalent of $5. what's supposed to bring long lifefe for believers usually spells death for the animals

after they're released. but a lucky y few turtrtles and tortoises s end up at acacc. like this one. it was also o released at a temple. michael: look at the carvings inside the shell. you know, mao, like sometimes the people scratch something in the shell when they gigive it o the monk? can you read it? mao: this one i think is for good luck. michael:l: this is a a giant an pond turtle.e. in this case, a relatively large male. we've received five of these, i think, over the past five years. it's listed as vulnerable on the red listst. we don't see them very often in markets here i in cambodia. that's usually a sign that a species has become relatively rare. we hardly ever get one as big as this.

reporter: the team is about to operate on the turtle. it has an injury inside the shell. for the moment, the animal gets a painkiller. next day, mao and her colleague prepare food for the animals. 600 turtles and tortoises live here, all them from endangered species. breeding them in captivity has proven difficult. but the elongated tortoises appear to need just fresh air and food. the rest they can manage for themselves. michael: when i started here 5.5 years ago, we had about t 20 elongated tortoises. ththanks to our breediding pro, we now have 330 at accb. that's not a bad start. reporter: so far, accb hasn't been able to release any elongated tortoises into the wild. it's too dangerous. the animals would be captured again in short order.

that's why michael meyerhof is hoping to bring the elongated tortoises here. this woodland is home to the last five large siamese rosewood trees in all of southeast asia. one tree can fetch more than 100,000 euros. this patch of forest is under guard, which could also offer protection to the tortoises. michael: we'd like to release the animals that are sexually mature into the wild, the ones that are five or six years old. we'll probably spend the next few years carrying out research to answer various questions. for example, about their use of habitats. then we hope to launch a pilot project with 20 or 30 tortoises that we'll tag with a transmitter and release into the wild. reporter: for now, though, the tortoises still need the shelter of the conservation center. and they need mao, who is tending to them.

mao: they like to come in evening time, that's why we put food in evening time. when they finish eating, they like to play with each other. the females have a lot of scratches here, but the males don't have, because the male is on the top. [laughter] reporter: perhaps this tortoise will be among the first released, so that one day soon a new generation of elongated tortoises will be born in the wild. host: we end the show with our visit to a global living room, this time in ecuador. ♪
