announunr: opportunity. prosperityty. optimism.. under, where thehe great barrir reef is in m mortal ngerer. and we head to chile, to see how farmers are dealing with rising energy costs. but first we go to afghanistan, to meet anan amazing woman who

against all odds is tackling the country's massive drug problem. afghantan n halongng beethe world'largest oducernd porter oopium the substancfrom wch heroin derived. and ever more, opium poppies are being planted. the united nations says the area under cultivation has soared 63% in just one year. and opium production has rocketed this year by 87%. much of the drug trade is now under the control of the taliban, for whom it's a huge source of revenue. opium and heroin use is spreading fast within afghanistan as well. a full 10% of the population is believed to be addicted. reporter: twice a weeklalaila haidari goeses down under thts bridgege in kabul. a grimim sight awaitits her --s by far the most horrific spot inhe a afghacapitatal.

the city's's drug addictcts are holeup h here, thousanands of them, just trying to survive this darark hell. the stench of excrenent, uri and vomimit is unbeararable. rats scurry y alonthe wawalls. every morning,g, between five d teten dead bodieies arcarrieied. laila haidi is t t angelff kabubul's drug-afffflicted. laila: if one ofof you wants o cocome with me, , you should sd rereporter: he d drug addictse irrible, a andggressiviv werere onlable t to filmecauause we came th laiaila the local police haven darared to set foot der r thbridge f f ages. 12 m respopo to laa'a's ofr thisis morning ---- the laste dedecidi at ththe st minutut laila putsts the men on n a bue had ararranged aheadad of time.

they areriveven to housese at thedge of f the city. laila: why do i do this? my brother was a drug addict. i had to watch him slowly lose everything.. first his job, then his family -- in the end, he gave up and died. reporter: for those who arrive here, the first step is to scrub the dirt from their bodies. then, everyone's head gets shaved. those who decide to leave behind the hell under the bridge should mark a new beginning -- also physically. laila often lends a hand. she is 42 years old, and an unusually strong-willed, independent woman in this deeply conservative country. laila owns a restaurant not far from the city center. it's popular with kabul's upper middle class. the money she earns here pays

for the drug addicts' rehabilitation program. a place to stay, meals, a few medical tests -- laila's therapy program does have lilimit. laila: i h have not forced anyf you to come here, you are all here of your own free will. i don't care if you speak pashto or dari, or to whom you pray. you can stay for one month. after five days, you will begin to do some light exercise. then you will be given a few tasks. reporter: for seven years, laila has been trying to help men like these get off drugs, without any medication. she tells them to drink as much water as possible, and that should be enough. mahdi: i have prayayed to allaa thsandnd times to shshow me te pathth away from drugs, to givee another chance. peperhaps it wilill happen to. reporter: ali palang has come out from under the bridge. he's been begging, searching through garbage, and when necessary, also stealing. ali needs money for drugs.

a bag of heroin costs around two euros. it doesn't sound like much, but by afghan standards it's a lot. still, there are more than three million drug addicts in afghanistan, around 10% of the populalation. ali: there's no work, people just hang around without any prospects. that's why people in afghanistan turn to heroin. i managed to get clean once for more than a year, but then i started again. reporter: this hill is another gathering spotot for kabul's dg addicts. they consume drugs here in the open. they are young, and old -- some are even children. the afghan police gave up a long time ago. some cash in on the problem. afghanistan is floodeded with drugs -- p production has increased in recenent years. this hill l is a place of desolation. afghanistan -- the world's biggest producucer of drugugs s now suffffering from t the dr'

curse within i its own border. but there is a bright spot in this story. mohammad alizada also lived under the bridge for many years, but he's been drug-free for two yearars now. he stayed d with laila, and hes out whenen the new arrrrivals n to make rugs. these are then sold to support the program. mohammad: i used to be a policeman. during my shift, i often came across alcohol and drugs. later on, i took heroin on a regular basis -- until laila took me in. reporter: and what would have happened if he had not escaped from under the bridge? mohammad: i'd be dead today. reporter: the men have started singing love songs again. for laila, that's a good sign. the withthdrawal procecess s

extremely difficult. of all the men laila takes in, only around a quarter of them manage it, and stay clean. her dream is to have a p propr clinic with experienced doctoro, so she can rescue many more drug addicts from the hell beneath the brididge. host: we heaead now to chihina, ere more and more people have a smartphonecomputer, or tablet -- anand internet u uss surgrging. morere than lf t the populatiois now online -- an estimated 755 million people. china is world leader in e-commerce, with sales this year of 452 billion euros. but censorship limits online access, and leading global players are not always welcome. chinese firms dominate the chinese web. there's wechat. baid the maisearch eine, the coterpart google. youku tuu -- chi's youtu. renren, ich likeacebook. and cotless otr servic. for cal provers, thehinese

addresessing the problem. reporter: it's not a bad life for a cow here. nowhere else in chile offers such lush pastures. and nowhere else in the country produces as much milk as the region around the city of osorno. adririana mohr has been a farmr for 38 years. her family came to chile from germany 170 years ago. she says milk has always been produced by natural methods on this farm, and she wants it to stay that way. adriana: we have to work with what nature gives us, respect nature and take what it offers us. but we mustn't harm it. that's the only way we can leave the earth in good shape for our descendants. reporter: at 4:00 p.m., it's time for adriana's 250 cows to be milked. the milking station's electricity bill comes to 1000 euros a month. energy costs in chile are high,

because raw materials needed to generate power still havto be imported. the high cost of power worried adriana mohr. she wanted to lower her overheads and also wanted a climate-friendly solution. so she decided to put a photovoltaic system on her roof, at a cost of 2400 euros. her energy costs are now 8% lower. adriana: the system generates up to 300 watts, and that's used straightaway for the milking process. so we don't use as much energy from the grid. reporter: but making a profit with milk is difficult for farmers in chile. they only get paid 27 euro cents a liter. adriana's farm is large enough for that to be enough to live on. it's not the farmers in chile who are raking in the profits, but the companies that process their milk.

at this factory, adriana's fresh milk is turned into milk powder. alejandro schilling, another dairy farmer with german roots, lives 50 kilometers away. with 1200 cows, his farm is one of the largest in the region. he says anyone who wants to make money with milk has to expand their farm. alejandro: s saving energy is simp an n economic facactor fr me. i've always saveved wherevei could, whether with energy or elsewhere. if you have a business, it has to be economically viable. reporter: a few years ago, alalejandro invevested close te mimillion euros s in large m mkg plant. 400 cows can be lklked herat a a time, saving employees and energy.

modern vacuum pumps make the milking process more efficient. but what alejandro is really proud of is the plant's cooling system. he loves to talk about it. alejandro: the milk comes from the milking shed through this filter. and through this filter, it goes to these coolers. the milk arrives here with a temperature of 37 degrees celsius, and is cooled by water that's 10 degrees. the milk is cooled to 18 degrees celsius, and then the water -- which is now warm -- comes out. reporter: that saves him a lot of money. now alejandro wants to make further investments. annika schuttler and her team from the german-chilean chamber of commerce have come to visit him. they advise farmers on

energy-saving measures and renewable energy sources. annika: the weather in southern chile is very similar to the ather in g germany. there's good sun exposure, but also a lot of rain. so photovoltaics is an option, but hydro-power might be even better. here we want to see if the conditions are right for building a small hydroelectric power plant. reporter: the team takes pictures to show to a construction company that builds hydroelectric planants. if the price is right, the small unit could be completed next year. adriana mohr would like to make further investments in renewable energy, without having to expand her farm. but for now, she doesn't have the financial resources. adriana: for that, we'd need a subsidy.

otherwise we wouldn't be able to protect our resources, and produce excellent milk -- mimik that tastes of southern chile. reporter: right now she's looking out for the next geneneration on her r farm. these heififers should s start producing milk in about one year's time. host: australilia's greaeat bar reef is s a breathtakiking natl treasure of immense beauty and diversity -- but it is under threat. in fact, it may be dying a slow death. coral bleaching events are becoming more frequeuent, leavg behihind devastation. in many places, the colorful underwater world has turned into a graveyard. repoporter: this h has got to be of theorldld's bt locacatis for a univertyty lectu. and ththesresearchchs, students and d assistants, , clad in bk wewetsuits, are e about to geo wowork. here, on lizizard island, , the
