>> hello, and welcome to "global 3000." have you ever wondered what you would do to survive, and how much money you'd need? well, in the slums of nairobi, sex is sold for less than the price of a beer. and for many women there, the sex industry is their only chance to earn any money at all. many have had to survive on their own since they were just children, and they've done so through sex work. it's just one of the issues we're looking at on this week's program. holding her ground - a ugandan activist fights for lgbt rights in her homeland. searching high and low for the

saola, an extremely rare bovid in vietnam. and representing the millennium - our teenager this time around comes from the caribbean. officially, prostitution is banned in kenya. but it's an open secret that it happens. it means that sex workers are often arrested, and are not legally protected themselves -- they don't get help from the police when their clients don't pay or even when they're the victims of violence. on top of this, fear of hiv-aids is widespread. aid organizations are trying to help and get women off the streets. but for many there seem to be few alternatives. reporter: monica wanjera lives in a slum on the outskirts of nairobi. she's 27 and has three children. their fathers do nothing for them.

to buy food for her children, she works nights as a sex worker. monica: sometimes you may go there, the street, you find those guys they are too harrassing. they beat you up. they even take your money that you have get for the kids. you come home without anything. you find the kids, they are hungry, don't have anything to feed them. it's very hard, and sometimes painful. reporter: monica had to start earning a living when she was 12, so she couldn't attend school anymore. she wants a better life for her children. monica: i would love to give them a good future, be a good mother, to be there all the time. not sometimes, i'm leaving them at the night when they are alone. i feel bad, when i'm away, and they are alone at the house. i don't know what could have happened to them. reporter: like monica, thousands of women sell their bodies here on the streets. many of them are still children.

for most of them, prostitution is the only way to survive, just barely, because in kenya, a woman costs less than a beer. >> like today, it has been raining, raining like this, and they are going to wait at home, because it's raining. weather is not good. >> how much money do you earn in one night? >> as you can see, this is a slum. only 200. reporter: hiv-aids is rife on the streets. the women live in constant fear of it. during the daytime, monica takes part in a workshop organized by an aid organisation. all the women come from the neighbourhood. all work in the sex industry. and they all have children they have to raise alone. here the young women are taught ways to earn money without

selling their bodies, because they all have the same aim -- to get off the streets. christine waither lives in the same slum as monica. she and her son share a space 10 meters square, with no electricity and no running water. christine was thrown out by her mother when she was 12. christine: i was living with other girls down here and didn't know how to make money. they show you how to make money. so when i went there i met this cop. i can't talk about it. reporter: you don't have to talk about it. reporter: despite that trauma, she still works as a prostitute

so her son can go to school, something she was unable to do. christine: this one, a chart for my son, to school. a for apple. you see, i want for him a better life. i don't want him to pass through what i did, what my mother did -- i don't want my children to be like this. but now i started having the child when i'm 15. i never wished to have them at that age. yeah. reporter: despite her misery, christine is trying to stay strong for her son. together with monica, she attends the self-help group in the neighboring district. here they share what they've learned with other girls, girls much younger than they are. and they try to warn them not to make the same mistakes they have.

many of the girls are orphans or were kicked out of their homes. they have no money and no education. without finishing school, they can't get jobs. their only option is the sex industry. that's how jane started. daniel: how old are you? jane: 15. daniel: and you are working on the streets sometimes? jane: yes. reporter: now it's monica who's trying to be her teacher. as long as jane has no children , she has a chance of escaping a life of prostitution, and perhaps even going back to school. for monica and her three children, that's a far-off dream, but she doesn't intend to give it up. >> would you like to go to school again? monica: yeah, i would love to, so i can learn more, show my kids how to live and to keep them, too.

show them how the school is important. reporter: christine, monica, and the other sex workers from the slums of nairobi were forced to grow up early. they know how hopeless their situation is. but they refuse to resign themselves to it. >> living a free life is something lesbian women and gay men in africa want, too. but in most african countries, lgbt people face discrimination, violence, and imprisonment. in three-quarters of african countries, homosexuality is punishable by imprisonment. in four, it carries the death penalty -- in mauritania, northern nigeria, sudan, and southern somalia. in 2014, uganda tried to introduce an anti-gay bill, allowing harsher penalties, including life imprisonment. ugandan president yoweri museveni even signed the law. but human rights activists, such as kasha nabagesera, are keeping up the fight, with international support.

she's one of the best-known activists in the lgbt movement in africa, and that's put her life in danger. but now she's been awarded the alternative nobel prize. the jury voted her one of the bravest women on the continent. reporter: she's travelled far and wide, and enjoys great recognition abroad. but in her home country, she can barely move about and has to hide away. kasha nabagesera is fighting for the rights of gays and lesbians in uganda. kasha: i've gotten beaten so many times, i can't count how many times i've been beaten. people have come out openly on social media and say if they get hold of me they're going to cut off my head, they're going to put tracks on my body, and all this. so i have to really, really always watch my back. reporter: she can scarcely leave her house. but for her, the threat has a positive side -- no one can deny

anymore that there are gays and lesbians in uganda. kasha: i live here with my partner and my cousin brother and his partner, so it's a gay house. [laughter] reporter: it's probably the only gay house in kampala? kasha: no, we have so many people living together secretly. some pretend to be best friends. others pretend to be actually married. so yes, you're in the pink village of uganda. reporter: there are said to be half a million gays and lesbians in the country. there are probably more. her rights organisation wants to use "bombastic," uganda's only lgbt magazine, to educate people. it's aimed mainly at non-gays. and they hold an annual parade as well. this year's in august was the fourth. there's a great deal of help from abroad. supporters of the movement donate money to the magazine. but back home, they constantly face hostility from the media,

just the people they need as advocates. kasha: these are the people we are living with. these are the people who are pelting stones to us, these are people who are pointing fingers, who are sexually abusing us, who are beating us. we need them to report positively, so that we can minimize the risks. reporter: in 2014, the government wanted to pass a law that would put gays and lesbians behind bars for life. after protests by activists and international pressure, it was overturned. among the people on the streets, ignorance and fear prevail. >> i reject homosexuality. if a man sleeps with you, you ruin yourself. >> but if you're poor and gays want to sleep with you, you can earn money. >> people can choose for themselves. if they don't want to be homosexual they don't have to be. reporter: kasha nabagesera's feelings of guilt bother her

more than rejection because of her sexuality. her mother died of a heart attack, many say because she feared for her daughter's safety. kasha: i almost lost my life after the loss of my mother. i abused alcohol, i went into depression, and then i said, "would she be happy to see me like this?" i just woke up one day, put the alcohol down, that medicine they gave, put it aside and said, "i'm not sick, i'm just being stupid. my mum stood everything, left, right and center. people threw words at her for protecting me, for standing with and she stood it. would she be happy to see me today drowning? picked up my bones and said back

to the fight! reporter: and more and more people in the country are following suit, even though they're frightened of newer, harsher laws in future. kasha: i am really, really hopeful for the movement in uganda. because even when some go, others come on board. so there is hope, there is no doubt. there is hope and the movement is strong, the movement exists. the challenge is there, but we also register some successes keep us going. reporter: the alternative nobel prize might give kasha nabagasera some protection in the future, and strengthen her in her fight for lgbt rights. >> our search for teenagers -- as young as the millennium -- continues and it takes us to the caribbean this week, and the little island of nevis. we found out about one fifteen year-old's dreams and aspirations for our series "i am millennium." shomari: my name is shomari mitchell. l live in barnes ghaut village nevis and have two brothers and

two sisters. i like real rap music. tupac, yeah, those kind of rappers who really letting you know how life is. i mostly listen to rap music, but i love my calypso most time. i take my music seriously, with my calypso. ♪ in the whole caribbean, we are number one set an example for the entire region ♪ i most times lay down in my bed and wait until my cousins often meet me, and when they meet me i normally change, and we go outside and play cricket, domino

by my uncle's bar. and yeah, we pick food and just have fun. what worries me is the young people, how i see them going up on the internet, that's not just good. i see -- most times i see young boys on music videos with their guns and saying how they gonna roll through other people's blocks. that's just stupid, that's just dumb. shomari: i don't live with my dad. he lives in trinidad and my mom works in town, shes a post lady. i love seeing my family together. that's what makes me happy. i love seeing when we have family reunions, i like seeing

when my families are happy. like my brothers and sisters, my younger sibling, my older sibling. i like seeing them happy. when they are happy, i'm happy. >> i wonder how shomari will see the world when he's twice his current age. and what do you think the world will look like in 2030? we've been asking people from around the world. you can find their answers in our online special at dw.com/my2030 -- as well as articles, videos and audio reports on the new u.n. development goals for 2030. world wide --- it's said

hundreds of species of plants and animals have disappeared. we've lost some in just the past few years --- while others -- haven't been seen by biologists for more than a century. take the tasmanian devil, for instance, or the south-american glaucous macaw. or less glamorous creatures, such as the australian bunny rat or the oman-i-undu reed frog from congo. then there's the sayola, which was discovered only 23 years ago, although it's lived in the forest between vietnam and laos for two million years. scientists want to protect it from extinction. but to do that, they will have to find one first. reporter: preparations for a wedding among the katu people, in the village of talang in central vietnam. the water buffalo is a present for the newlyweds. people here live close to nature and their traditions, like a lang lap.

a lang lap: hunting was always one of our traditions. i'm sorry when i kill an animal, but we live from them. animals are our food. reporter: he used to catch deer and wild boar. but once, he tells us, he trapped an animal he'd never seen before. a lang lap: at first i thought it was a mountain goat, but it had very long horns. then i told the other villagers and the village elder about it. he said that if this animal had white spots on its head, it was a saola. reporter: the saola is an extremely rare bovid, almost completely unknown. it's thought to have lived here in the mountain forests between

vietnam and laos for about 2 million years. i dream of seeing a saola. and even if i got a glimpse, a two-second glimpse, it would make all of this, all of the years of hard work, it would make it worthwhile. reporter: andrew tilker knows the saola only from photos. here, at the far right in the picture, the last image from a camera trap. the american biologist has been studying large mammals in vietnam for three years. scientists first discovered the saola in 1992. since then, there have been five photos. with his team from the world wildlife fund, tilker works in the forest for weeks. they're worried that the world's last saolas could die in traps like these at any time. andrew: nobody knows how many saola are left in quang nam or

vietnam. it could be up to 100. it could be that we can count the number of saola on one hand. so it's really searching for a needle in a haystack. reporter: these leeches might help him. they're a bit like thousands of tiny camera traps. andrew: the leeches are feeding on these animals in the jungle. the leeches are easy to find. usually they come to us, because they want to feed on us. so we can collect the leeches and analyse the dna in the leech to see what they've fed upon. reporter: from the forest to the laboratory, he and his colleagues have sent about 20,000 leeches to institutes in china and germany. in thousands of samples, no saola blood has been detected. what if the saola is already extinct? andrew: just assuming there are no more saola left, there are

other important animals in the forest that are critically endangered and the leeches can help us protect those animals. there is a monkey called a red cheng duc, there's a tiger-looking rabbit -- that's really cool -- it's a rabbit that's striped like a tiger. it's only found in laos and vietnam. so it's not just about the saola, although the saola is kind of the star of the show. it's the rarest, it's the most charismatic, it's the species that is in the most trouble, we think. reporter: that's why people in the region are being persuaded to hunt as little as possible. a lang lap's family get money from the government, about 30 dollars for three months. they use it to breed fish and buy rice to grow as a crop. a lang lap: it's not hard to cultivate rice, and as a rice farmer, i don't spend so much time away from home. but i can't earn nearly as much

as by hunting. reporter: how can you convince people to protect animals? the wwf staff visit villages and explain using simple games. the aim here is to avoid traps while blindfolded. it's hoped vietnam's biodiversity will attract tourists to the region, which would benefit the villagers. the mysterious saola is now known outside vietnam as well. >> more than anything, illegal hunting and destruction of the forests threaten our saola. i'd be so glad to see a saola. i think of it as a member of my

-- i think of it as a family member. it must look beautiful. reporter: what excites scientists like andrew tilker is a whole new species, a relic from the ice age, still completely unresearched. at 31, he saw a saola for the first time in the region's forestry ministry. workers had found it dead in the early 1990s and had it stuffed. a lang lap: when i see a saola like this or even just saola horns in one of the villages that i am travelling to, it helps to keep the image alive, it helps refresh that image. it reminds me that it is not just a figment of my imagination, but it's a real thing. reporter: tilker will remain in vietnam for another year, then finish his doctorate. but he fears one animal will be missing from his work -- the saola.

>> now, you might think that europeans have pretty high standards for their bread, but for moroccans they're even higher. they like their bread to be baked right in front of their eyes. and they like to choose the filling themselves as well. global snack goes to the moroccan capital of rabat for some pretty special street food. reporter: the historic quarter in rabat, the capital of morocco. hungry people are spoilt for choice with all the food on offer. many stop at abdelkbir nani's stand. he's set it up in the same place for six years. he used to earn his money doing odd jobs. now, at 29, he's his own boss.

abdelkbir: it's busy here. i make enough for my two children, my wife, and myself. reporter: a snack costs 7 dirhams, just under 65 cents. a pita bread customers can fill with whatever they wish -- fried fish, aubergines, potato patties or peppers, of course all home-made. the spicy chilli sauce is his speciality. it's a popular place. >> it's cheap and it's fast. i'm just passing through. it's really practical. that's why i eat here.

>> the fish is delicious, especially with potatoes. reporter: regular clients, travellers, and families shopping late in the evening -- the boss has all sorts of customers. but competition is fierce, so in future he wants to offer even more kinds of fish. >> and he could set up outside us here. on that tasty note, we are going to have to leave you, unfortunately. that's all we've got time for on this edition of "global 3000." you can watch this and other episodes again at dw.com/global3000. on behalf of the entire team, and from me, thanks for watching and please join us again next time if you can. until then, take care, and bye now.
