Corruption problem. This costs developing nations an estimated 1 trillion u. S. Per year. But the global fight against corruption is gathering pace. In russia, young people have been taking to the streets. In south korea, public demonstrations helped topple the president , whos now standing trial on graft charges. Theres also growing unrest in morocco, where thousands have been protesting government corruption and abuse of power. For months now, people in brazil have been demonstrating in support of a police probe into highlevel embezzlement and bribery. In mexico, meanwhile, corruption is part and parcel of everyday life. Reporter its 6 30 in the morning and time for the boss to be picked up. 400 Traffic Police officers are under the command of commandante rosalba. Her unit is made up entirely of women. Their job is to restore public faith in the police force. The morning ritual is always the same rosalba urges her troops to respect the rights of citizens. Such respect is not always a given among mexican police. Commandante rosalba travels hundreds of kilometers every day, keeping an eye on the policewomen under her command. Her goal is to ensure there are no mistakes. Rosalba were not as corrupt as perhaps some of our male colleagues. As a woman, i feel a sense of responsibility. I know very well that if i do something wrong, i can lose my job. Reporter rosalba isnt afraid to intervene personally where necessary. Here, a truck is blocking the street. The chief directs the traffic herself, until a patrol unit arrives to take over. Not all of rosalbas policewomen are immune to corruption. There have been individual cases of wrongdoing, drawing a tough response. This truck driver is issued a ticket. There is no protest, and no offer of a bribe. Men seem unwilling to try and strike a deal with the female Police Officers. There are rules. I have to do what the officer says. Reporter the exchange is amicable and the driver goes on his way. Then its time for breakfast. The thinking is that if there are more women in the police force, therell be less police corruption. The theory seems to be working. Rosalba for every 100 complaints about corruption we used to get, now we only get one or two. So its possible to change. Reporter the female traffic officers enjoy tortilla, eggs and ham for breakfast as much as their male colleagues, but thats where the similarities end. Theres anger when the unit watches a video of male Police Officers extorting bribes from drivers. Theyve been fighting this kind of behavior for five years. We always have to give them something. Yes, they get their tip. Reporter rosalba is adamant that women have more respect for family values and religion. She always keeps a copy of the bible with her. She says the reputation of the male officers is a disaster no one trusts them anymore. We women are just better. Men whether theyre policemen or not just come here to the market to steal from us. Reporter the clean image the women enjoy also has to do with the fact that the femaleonly police unit has existed for just five years. Its not burdened by a checkered history, or old structures. Rosalba takes a lunch break with her grandson mariano and daughter rosa. Her mothers work inspired rosa to become a lawyer, even though rosalba has a few enemies among her male colleagues. Rosa sometimes people said really bad stuff about my mother. It was pretty mean, and that hurts, of course. But thankfully it seems to have just made her stronger. Reporter its made rosalbe so strong, that she is now studying law herself in evening classes. She wants to be even more effective in her fight against corruption. Rosalba i dont tolerate corruption. Not one bit. If mofficers dont do their work properly, theyre going to have to pay the consequences. Reporter commandante rosalba as a grandmother, loving and tolerant. But shes one tough cop. Host recent years have seen mexican farmers growing opium poppies to feed the growing demand for heroin in the u. S. Its current addiction epidemic began with massive overprescription of opioid pain relievers in the 1990s. With big pharma aggressively marketing the drugs and downplaying their addictive nature, sales quadrupled between 1999 and 2014 and their potency also increased. The number of addicts and drug fatalities is skyrocketing. In 2015 alone, 33,000 people died of an overdose. The government has attempted to stem prescription opioid abuse by making them less available. As a result, more and more people are now switching to heroin. According to a recent national survey, nearly 2. 6 million americans have used heroin. Reporter corey long is 24. He likes to play guitar. He has a girlfriend, a high school diploma, and a job. And he is recovering heroin addict. Opioid drugs were once considered a problem exclusive to americas inner cities. But in the past few decades, they have also crept into the lives of wealthy suburbanites. Corey started using heroin in an attempt to improve his social life. Corey there was a pattern my whole life of feeling like i wasnt good enough in friend circles, feeling like people didnt really want me around, feeling less than. And when i met these friends that i was that i started doing drugs with, i felt the complete opposite. I felt like i fit in completely, i felt like we were all the same, they wanted me there. Reporter corey was one of the lucky ones. He had a supportive family, a steady job, and a roof over his head. But heroin took a serious toll on his life, as he watched his friends die from overdoses and experience druginduced psychosis. Corey i was either masking my withdrawal or masking the fact that i was high constantly at work, around my dad. It was just mentally exhausting, the web of lies that comes with using a drug like that. Reporter mike gimbel is a counselor and a consultant at the maryland Addiction Recovery center. Hes also been a recovering addict for the past 44 years. The current Opioid Epidemic has to do with doctors overprescribing pain medications to patients, and International Cartels introducing new kinds of powerful synthetic drugs like fentanyl to the market. Mike why arent we dealing with it . Theres a lot of denial in certain areas. Middle class neighborhoods or schools, they dont want to admit that their kids are doing heroin. Families dont want to admit it. By the time they find out, sometimes its too late. So its a matter of waking up the public about this awareness, and then the government is certainly not doing their job in providing the resources. Treatment thats treatment resources number one on the list of what we need that doesnt exist. Reporter but as opioidrelated deaths continue to increase across the country, the u. S. Government is beginning to take the problem seriously. In march 2017, the governor of maryland declared a state of emergency to combat the epidemic. But with many people ending up in jail before they manage to find a treatment program, gimbel says more funding is needed. Mike 35,000 to 40,000 a year to keep someone in prison. And they come out, and 70 go back. We can treat them in one of these residential programs for probably 10,000 or 15,000. And we have a lot Better Success rate in treatment than we do in incarceration. We need that money. If were willing to pay for it for jail, we should be willing as a country and a government to pay for the treatment. Reporter corey long now also works at the Addiction Recovery center, helping other addicts through the difficult process of getting clean. Two years clean himself, he is now looking forward to the future. Corey im really excited to be moving in with my girlfriend, and starting a life with her. Im also excited to be able to devote more time and space to my music. Reporter according to estimates, only 20 to 40 of drug users ever fully recover. But corey is optimistic hes beaten the odds. With the help of his loved ones, hes ready to move on. Host the Destructive Force of substance abuse. Its also a probm in the philit Rodrigo Duterte is waging a bloody crackdown on the drug trade. A lucky few have been able to find help. Reporter uniformsre compulsory, here at the treatment and Rehabilitation Center for drug addicts at camp bagong diwa in metro manila. Patients wear white tshirts with red shorts, which either they or their families have paid for. Those sent to rehab with dr. Leabres are charged 80 euros when they begin, and then 60 euros a month. Those who cant afford the fees are given subsidies. Dr. Leabres our challenge is to help people understand that an addict has a medical condition. He can be a frie, he c be a relative, he can be your son, or your husband or wife and all of this is part of you. Help them. Reporter but not everyone is heeding this message. Elected president in 2016, Rodrigo Duterte is waging war on drugs. 8000 spected drug pushers and users have been kied, many at the hands of the police or socalledeath squads. More than a million have voluntarily turned themselves in and gone to prison in a bid to survive. The prisons are filled to bursting. And for these people, going cold turkey is a matter of life or death. Others volunteer to go into the killings arent right. Since duterte has been in power, ive been afraid for my life. Its safer here. I also need to think about m wifes suffering. My child and my wife are really the worst affected. Reporter treatment is supposed to entail training, occupational therapy, counselg, and followup care. But with only 12 doctors per 1000 inmates, its impossible to see through. And the total count of drug users in the philippines could be as many as four million. President dutertes drug war has been described as mass murr. But hes proud of what his country is doing to counter the povertyfuelled wave of drug addiction. A chinese tycoon funded this giant new Rehabilitation Center. An irony, some might say, given the role played by chinese gangs in the Philippine Drug trade. President duterte i will not allow my country to sink like colombia. I will not stop until the last pusher, until the last drug lord is exterminated. That will be the rule of the day. Reporter 100,000 square meters of space for 10,000 addicts. But just 186 patients are being treated here. Theres a serious doctor shortage. There are only 13 federal drug clinics, so local governments are at the forefront of the fight against drugs. In olongapo, the mayor has formerddicts building coffins provided to poor families who cant pay for funeral services. Robert since i began taking part in the mayors project, i finally have work. It was good that i turned myself in. Reporter for many of the former addicts, this is the first time theyve had a chance to learn skills and earn a wage. Angelito we have hope once again. Somethings changed. Someone cares about us the mayor and the department for business startups. Reporter mayor Rolen Paulino hands out chocolates and chats with the trainee craftsmen. He wants to turn the jobsforaddicts scheme into a cooperative that builds and sells furniture. Mayor paulino i said, do it properly and change yourselves, otherwise the coffin you are making might be your own. Reporter elsewhere, recovering drug users are encouraged to exercise and eat well. Joan we see zumba as a priority. The participants can detox their bodies, and they can make new friends. And then they are more likely to cooperate in our program and to get healthier. Reporter thats the theory. But it will be difficult to improve the addicts longterm behavior if they have no livelihood and no motivation to change their habits. Julie lifestyle if you want to be poor, you always want to be poor. You just want to ask something from those who have already. If you dont have any notions, visions in life, to elevate your conditions in life, thats the problem. Reporter those who are here apparently do want to change, and help is available to them. Pickled milkfish is a big seller at markets across the philippines. Cleaning it and preparing it is a way of earning a living. Benjie i have a hard time working with food i always left that up to my wife. I used to just sit down at the table when i got home. But ive got better. I want to change while im here. Reporter the patients at the bagong diwa rehab clinic need more than occupational trapy programs. Proper treatment can help even the toughest of inmates. How do you feel, asks dr. Leres. Fine, answers the patient. Lonely . No, im happy, he says. Ive learned my lesson and i will change my life. S spell in rehab might have been rough, but it probably saved his life. Out on the streets, the killing continues, overseen by the president himself. Host what can be done to help drug addicts . Series. This is when we meet people dedicated to conserving our natural world. This week were in the Serengeti National park in northeast tanzania. A population explosion has gone hand in hand with growing demand for grazing land for livestock. The troue is, wildlife needs it, too. Our reporter inga sieg and cameraman Axel Warnstedt wt to the serengeti to see how the park and the region around it are faring. Reporter the lions dot need to worry where their next meal will come from. Millions of wildebeest, zebras and antelope traverse the Serengeti National park every year in the largest mammal migration in the world. But the park is in danger. Conservationists rian and Lorna Labuschagne have been working in National Parks for over 30 years. Now theyre here inhe serengeti,ighting to protect its animal populations. Rian any illegal poaching or killing of animals is a problem for that ecosystem, because it puts it out of balance. Here in the serengeti, here they use this snaring method which is devastating on big populations of wildlife. Everything will be killed. Mostly wildebeest, zebra, impalas, but if they put up a whole snareline sometimes over 100 snares, what ever goes in there. Reporter this patrol unit is made up of park rangers and former poachers. Theyve collected more than 100 snares today. Most of the poachers come from villages on the edge of the park. Rian they know how to do it, they have got years and years of experience. Animals walk into the snare and the cablewire pulls tight around the neck, sometimes around the foot, and the animal is then strangled and killed. Reporter the animals of the serengeti know no borders. There are no fences in the park, and animals and humans live in close proximity. Masegeri rurai lives in the serengeti buffer zone. His job is to safeguard the park, and that means protecting it against humans. The Current Population of tanzania is 50 million. But that could double in coming decades. Masegeri population growth for the serengeti means more increased consumption of natural resources, and that means more pressure for the wildlife. Bushmeat, hunting, and also grazing. Listock is increasingly big problem. [crowd singing] reporter cocoba is a community bank. It allows up to 30 villagers to pool their savings until they can afford to invest in something the village needs. Many of the participants in the scheme are former poachers or locals who used to live from their cattle. Now theyre small businessowners. Masegeri the goal of cocoba is to enable communities to be empowered economically tengage into more sustainable Economic Activities which support conservation in more positive way. Reporter in populated areas, Domestic Animals pose yet another risk to wildlife. Cows and goats graze on land the wild animals need. This is tolerated on the edges of the serengetiin order to avoid alienating locals. They administer these areas themselves, and income from tourism ploughed directly into the villages. The edges of the park are less spectacular than its center, but a growing number of visitors are findg theiway here, too. Relations between villagers and conservationists are less tense than they used to be. Sospeter yes, we need more money, we need more money from tourists. But also we need the people, we need to serve the people. Documentary written and directed by berard grzimek. The Academy Awardwinning film helped make the park worldfamous. Nearly 60 years later, its more topical than eve rian sometimes its difficult for us whoome in frothe outsid who has to transfer new ideas to the Tanzanian Team here, to really get the message over. We as Frankfurt Zoological Society stand a little bit away and look at the whole picture from afar, and then we can see shortcomings in certain places where we feel well with experience we have, because we work internationally, experience we have from other places. We can bring that experience to the ground and help the local management to be more effective in what they are doing. Reporter back in the buffer zone, Masegeri Rurai is visiting the New High School. The first and only one far and wide. Masegeri which animal do you like most . Elephant . Giraffe . Lion . Do you know the serengeti is one of the wonders of the world .
