Its been a year since news emerged of the agonizing deaths suffered by hundreds of thousands of saiga antelopes in the kazakhstan steppes. The cause an aggressive bacteria. That much was clear. But why was the damage so extensive . A group of researchersrs are determined to find out, and our cameraman Axel Warnstedt jnened them o on their quest. But its difficult to locate the few remaining animals. The antyn dala steppe is vast, and on top of that, saiga antelopes are very shy animals. Inga these researchers have for saigas across the vasts, log grasslands of the kazakh steppe. Steffen the greatest challenge is finding the animals, because their population is now much smaller and we dont know exactly where they are. We sigighted them when we took a count two weeks ago, but afterwards they went elsewhere and no one has seen them since then. The territory is just incredibly large. Inga the protected area is as large as france. Its like looking for a needle in a haystack. After the mass dieoff last year, the saiga antelope population was left decimated. Here alone, in the largest saiga population, more than 200,000 animals died. 90 were wiped out in a matter of days. Steffen i was shocked. I was s in the fieldld myself ad saw withth my own eyes the first dead saigas s lying there. It was the first place where it happened, and i was right there. Inga 5000 animals are buried ununr this hilill. Its the first time Steffen Zuther and the british antelope specialist richard kock have returned since the great dieoff. They want to find out why so many saigas died. The pasteurella bacterium, which led to the deaths, has been the researchers alsoso know at before thehe dieoff thehere waa huge drop in temperature. Richard and the animals were very stressed. They lost their coat. They dont have their winter coat, so the stress, inn combination with exposure to bacteria or the presence of bacteria, leads to the invasion of the bacteria into the body and d rapid death. H. Peracute, five hours, 12 hours, dead. Inga there have often been mass deaths among saiaiga antelopes, but t never of such magnitude. E. Why did all of the infected animals die . And how could the disease break out in different places at once . The expedition aims to shed light on that, but first the researchers have to find the animals. Day fofour of the search, a meeting withth rangers theyre supposed to lead the expedition to the saigas. But theres a problem. The only two animals with radio collars have separated from the herd. Steffen they said that here in the region there are only small groups of saigas left, that you can see them but not get near them. Inga no saigas far and wide. Only mosquitoes are here, all the time and everywhere. Frustration builds after four unsuccessful days of searchihin. But then, ththe next morning, theres a glimmer of hope. Theres some saiga footprints hehere. Fresh. Richard you can see, you know. They are here. So, we have footprints now. So, its not far. They are extraordinary a animal, the waway they move. E. Obviously calving is the only time that we can really get anywhere near them. The ananimal runs at 70 kilomets per hour. Steffefetells me they will run 100 kilometers in one day. Inga the saiga footprints havent helped. The search is increasinglyly becomiming a test ofof patience. And time and again, new sesetbas its rained too much recently. The fear i is that the plalace e steffen and richard suspect the largrge herd might be is inaccessible. Another day without success. Erect our tents, andnd hope. The next day something happens that no one had expected anymore. The spirits of the steppe are there. The expedition has achieved its aim. You see i it . Oh, wow. Steffen now weve fininally fod saigas. Weve travaveled a long way. Theyve hidden in a place thats very hard toto reach. On our w way weve s seen that e are now at least 2000 saigas. Inga the animals have gathehd 100000ilometers s deep in thee ststeppe to bear t their you. Most of the calves are already on their legs, and theyre evididently doing well. Now the scientists can start t e real work. That includedes weighing and measuring the calves. Steffen w we want to carrrry ot conventional monitoring on the state of the calves. In other words, to find out how many there are, the density of the calf population, in order to see how reproduction is going. Inga a tissue sample should show whether there are pasteurella bacteria in the calves bodies, the usually harmless bacteria that became lethal pathogens last year, kikilling all the animals. Steffen basically were where we were ten years ago. And these mass dieoffs can happen again. To preserve this species, its very impmportant to ununderstand just w what happened a and whetr anything can be done to combat it. Ga despite extremee environment, poaching, and mass mortality, kazakhstans ancient animal has survived d for millennia, but cononservationiss are worried that another mass dieoff could be the last. Narrator rhinos have been under threat of extinction for many years. Both the black and white species are found in the Southern African countries of zimbabwe, kenya, namibia, and south africa, which now has a population of around 21,000 rhinos. But that number used to be far higher. The horns s of the animals are very valuable, which makes them an attractive target for poachers. Since the turn of the millennium, theres been a dramatic rise in rhino poaching. Rhino horn is worth billions on the black market, fetching an average of 60,000 u. S. Per kilo. The battle to end poaching is a tough one, but the outlook isnt entirely hopeless. Reporter Kruger National park in south africa nowhere else in the world are there so many rhinoceros, and nowhere else are so many killed by poachers. The Investigative Unit is on its way to the scene of a crime. The helicopter spotted a rhino cadaver and marked it using gps. Frik ive been in kruger for 28 years and since 2005, 2006 this started escalating. You can get used to a lot of things, but you dont get used to the slaughter of these ananimals. Reporter on foot and heavily armed, they get going. There could be predators in the area. Then, all at once, they spy the colossus lying in the grass. Frik and his coworkers, who want to remain anonymous for security reasons, examine the scene in detail, to reconstruct the dramatic last minutes of the animals life. That could help them catch the poacher later on. Frik we are looking for anything that can link you to the suspect, whether its the tracks that he leaves, any dna he might leave behind, finger prints, the ballistics left behind by the weapon, whether its the shell casing or a bullet anything that can link you to t the suspepect. Reporter the fight against poachers in Kruger National park resembles a war. Theres a command center, from which all the antipoaching measures are controlled. Using a special computer system, every incident is localized. In 2015, poachers in south africa killed a total of 1,200 rhinos. The illegal trade in rhino horn is a business worth billions. A few hundred kilometers away,y, west of johannesburg, lies buffalo dream ranch. Here, too, people are fighting the illegal rhino horn trade. Veterinarian Michelle Otto is up early to do some hunting, but only with a tranquilizer gun. Thats because rhihinos are bred on this farm and their horns are trimmed on a r regular basis. The idea is to legalize the trade in horn with the intention of making poaching unprofitable. Michelle this hororn part thaht were trimming is basically like a fingernail. Its keratin, its like the hoof of a horse. Its like cutting your own haiai for r instance. The section that were trimming is the part that has no blood supply, it has no nerve endings in that specific section that were cutting. So, its basically like just going for a manicure. Reporter 1,300 animals live here on the Worlds Largest rhinoceros farm. Rhino horn grows back, so it can be harvested several times. Each gram is precisely weighed, catalogued, and then securely stored. After all, the keratin is more valuable than gold or cocaine. In asia, its considered a miracle cure. At the other end of the world, in san francisco, those wanting to protect the rhinoceros have two allies. George bonaci is a chemist. In his recentlyfounded company, he creates rhino horn in a laboratory. This is hohow artificial rhino horn will look someday. Cofounder Matthew Markus proudly presents the first prototypes. Matthew the b black market prie right now theres ranges from 30,000 to 100,000 per kilogram. We are targeting 7000 per kilogram. We think that will be a good price point that puts a lot of pressure on the poacher and poaching syndicates, because it will be harder for them to make money, to bribe officials. Reporter rhino horn consists mainly of natural keratin. George bonaci mixes it with other substances. Exactly what they are remains his secret recipe. The liliquid is later drdried ia kiln and then turned into horn powder. Thats what the biotech startup wants to sell. China and vietnam could be the main markets for it, because rhino horn is still in high demand there. George we are going to be looking at shark fins which are very popular in china, pangolin scales, which are also made of keratin, tiger bone, which is alsoso used in t traditional che medicine, ivory, which obviousuy has a lot t of history in the wt for use in durable good products. Anything where an animal is used in tradition, we wanant to be ae to remove thatat animal from t e goods chain. Reporter so, there are several ideas on how to curb rhinoceros poaching. For many animals in Kruger National park, theyve come too late. Almost every day, frik rossouw and his team have to go out to secure cririme scenes like t ths onone. In this case, its especially distressing. The rhrhino, a female, was pregnant. Narrator hunting and being hunted for wild animals life is always about survival. And its no different in kenya. In some of the villages here, people and elephants are sworn enemies. And thats where a very special story begins, the story of elephants whose survival is all down to bees. Reporter farmer nashon mwaghare has finally been able to harvest numerous sacks of corn. He leased the field ten years ago, when his first child was born, but a powerful enemy appeared, one that constantly stole his harvests. Nashon we would sow the seeds, but just before harvest time, the elephants would come. Sometimes they came before the corn was even ripe. They would eat everything or trample it. Everything was destroyed. Reporter they always came during the night and tore up the field. It was a desperate struggle between humans and animals over land and sustenae, a strgle that claimed victims on both sides. But for nashon mwaghare, that struggle is now over, thanks to help from the elephant and bees project. Project teams constructed a fence made of beehives along the perimeter of his field, and the small insects are having much more succecess than the humans ever did. Should an elephant come into contact with the wire connecting the hives, all of the bees emerge to defend the colony. Lucy these african honey bees are very aggressive, and this is the advantage of the method. Once they sting you, they release a pheromone on your skin that causes the other bees to come and sting in the same location. Now this is an advantage for elephants. So if they sting on the elephants trunk, the other bees will come to the trunk and sting again. Reporter thats how these tiny davids get the huge goliaths to beat a retreat. If theyve been stung once, their famously good memory ensures the elephants avoid future contact with these nasty insects. Just the sound of their loud buzzing can throw the elephants intoto a panic. Matthew we can see there was a group of elephants, it looks like three elephants in total here, that approached his farm, came around the corner, were even around the side of his fence. Saw that there were bees there, or even felt, heard, or smelled, and ththey decided to proceed around and go another way because of those bees. Reporter and the farmers, who once went hungry, actually gain two advantages thanks to their little helpers. They can finally harvest their corn, but they also now have additional income from the honey the bees produce. And theyre no longer killing elephants, like they used to, when they desperately tried to defend their fields with drumming, stones, and spears. Mzumo those are my friends by now because they dont disturb me when they come here to my farm. Thats what i know. Theyre my friends. Before that, they were nearly my enemies. Reporter nashon mwaghare and his wife say its a miracle e ad tell us all of their neighbors wanted to hear how it worked how the bee turned humans and elephants from enemies into friends. Narrator so it seems Creative Ideas are worth their weight in gold when it comes to overcoming problems. The Global Shapers community is a worldwide collaboration of young adults whose aim is to use their ideas to make our world a better place. Suz is dedicated to helping chilildren in her home country f myanmar. Franklin from panama works together with young people to improve health care in his country. And elaine from vietnam wants to beautifyfy her hometown ho chi minh city. And today we introduce you to a Global Shaper from indonesia. Reporter every morning esri nurhani prepares the food shell later be selling at the market. Shes a microentrepreneur. Her snack bar ensures her an income with h which she e suppos her family. Today she has a guest, 29yearold andi taufan. He recently gave her a small loan so she could start her business. Esri nurhani invested in cooking utensils and basic ingredients. Esri every day i spend around 150,000 rupiahs and sell the food for 200,000, so my profit is around 50,000. Reporter 50,000 rupiahs a day are the equivalent of almost 3 euros 50. Its not much, but its enough to make ends meet. Andi taufan has helped many people build up a livelihood. His organization offers microcredit to groups that organize themselves. Andi engage them with us. Try to invite them to participate and to make them accountable. The way we can do it is by creating a social control by credit groroups. The group mechananism can ensure that every members can also taking care of each other. Reporter the loans go mainly to women. Taufan founded his organization, amartha, six years ago. To date hes supported 20,000 people. Most come from rural areas. The aim is to help women who have difficulty getting credit from a bank. And andi taufan does more. Together with friends, hes founded a platform that funds eyeglasses for rural women glasses the women couldnt afford otherwise. Taufan is not yet 30, but for him, commitment to social causes is a matter of course. Andi if we talk about young people, they have the drive and the commitment not only for themselves but also to find solutions for the most pressing proboblems, especiallyly if we k about indonesia. We have so many social and economic problems, also environmental problems. That is the dynamic. Thats something we are eager ro face. Reporter andi taufan gave up his wellpaid job as an engineer to devote himself entirely to his organization. Many people in indonesia are poor. They get little benefit from the countrys rapid economic growth. Taufufan is convinced that a lot has to happen for that to change. He meets up with friends in jakarta. Theyre doctors, bankers, musicians, and it entrepepreneu, and theyre members of the Global Shapers community, a Worldwide Network made up of young people under the age of 30 with h plenty o of motivatiod commitment. Stella with 250 million people, we can actually do a lot, but the thing we are lacking at the moment is the right kind of resourceces, the right kinind of skills, the mind set which could solvlve a lot of internal probls in this country and also globally. Andreas actually we have to promote more tolerance in society. It can be promoted through music, because in music we have so many different kind of sounds, different instruments, different genres but still we can create harmony. Reporter Andreas Arianto is banking on the power of music, and, together, the Global Shapers are banking on change. [applause] narrator and finally, we head over to chile and trtry out a popular snack which is both food and drink in one. Reporter miguel onatelaria is dissatisfied. His snack bar is wl l situated. Its in the middle of the bus station in the chilean town of santa cruz. But things are slow this morning, so miguel tries to drum up a little business. Miguel [speaking spanish] reporter motete con huesillosos a thirstquencher that conontais wheat, so its more of a snack than a drink. Just take mote, or cooked husked wheat, add dried peaches, and top it off with the liquid in which the pepeaches were cooked. Miguel it has to simmer for a good amount of timime, then its cooled and sweetened, using not too much sugar, but it has to be sweet. Would you like to try it . Reporter miguels been here for more than 30 years. His snack costs the equivalent of 1 euro 30. Thats not cheap. The average monthly inincome in chile is just over 900 euros. But miguel knows how he can atattract customers at t the bus station with a wheat drink or a portion of french fries. Miguel weve had to sacrifice a lot. Thats the only waway we were ae to succeed. Were a perfectly ordinary middleclass family, b but we he a loloof energy. Y. And its thanks to this beverage that my son can study at ununiversity. Reporter customers at last this couple is thirsty. Are they hungry as well . With motote con huesillos, you dont have to decide. Of course the lady gets the first taste. Its really delicious, made with natural ingredients, without additives.
