they have done everything to fulfill their parents' expectations. from a good education, they have also made a transition to a good job. yet they fail in one of the benchmark disciplines of chinese society. finding the right partner. the doctors and the suns -- the daughters and sons are certainly used to pressure. once they hit their mid-20's, they soon give up, leaving this matter. no wonder dating agencies are mushrooming all across the country. >> they would like to find a bride for the sun. they would like her to be pretty and intelligent, but not necessarily over educated. an online dating agency organized this public marriage market. they are increasingly common in china and so are parents that

want to marry off their children. that has always been a part of chinese tradition. these days, they go about it differently. >> my son has always been very busy with this career. he has not had time for love and romance. we are very worried about it. because he is almost 30 and is still isn't married. >> there are far more men than women in china. population experts warn that by the year 2020, china will be home to 24 million single men who will have no hope of ever finding a wife. these chinese bachelors are known as the bare branches. this 29-year-old does not want to join their ranks, but he complains that women today have elevated expectations. >> all the women are looking for men with department and cars.

that is in keeping with chinese tradition. it is standard practice that a man has to be able to offer a home. a car is part of the whole status symbol package, too. >> but the shortage of women and the high expectations, he is not getting his hopes up. the problem is rooted in china's one-child policy. parents can have a second child is their firstborn is a girl. in many parts of the country, the boys are given preferential treatment. experts say that some families only have the second child if they are certain is a boy. >> two girls are not what most families want. if the second child, they make a choice. these days, it is easy to determine the sex of a fetus during pregnancy. the government has banned the use of ultrasound scans, but people do it anyway.

>> girls are too often aborted. the result is that china now has a surplus of man. theoretically, that means women can pick and choose their husbands. nonetheless, at this 32-year-old has paid a dating agency it the equivalent of 3000 euros to help find a husband. for many chinese, that is more than they earned in the year. she can afford it. she has a university degree and an excellent job in a big company. she sees it as a sensible investment in her future. >> i am looking for a man who is superior to me, whom i can respect. he should have a better education and earn more than i do. that is the sort of man that could make me happy. >> the marriage market is a highly profitable one, with growing numbers of chinese using dating agencies. there are many young women in

china today, high achievers to expect a lot. there would not dream of saddling for a migrant worker or a farmer. -- saddling -- settling for a migrant worker or a farmer. >> we see a lot of women like this. they're difficult to place because they are rather demanding. they want men to meet their high standards. >> she is meeting a candidate for the first time on the premises of the agency. they're both nervous. unfortunately, there is no chemistry between them. it is a shame because -- it is a shame, but worse for chinese society. if the trend continues, said the experts, china risks getting old before it gets rich. >> in the past, the government

promoted the one-child policy. this led to a steady decline in the birthrate. there are fewer young people. at the same time, the population is aging. the number of old people is growing rapidly. >> of the exodus of people from the countryside to the city is exacerbating the problem. urban anonymity is not conducive to romance. it is rush hour in beijing and allows us is on the road. these speed data is climb on board, introduced themselves, and hope that a young lady shows interest. if someone holds up a smiley face selling, they can sit down and talk for seven minutes. >> unlike online dating, you get to see each other and it can start conversing right away. it is a novelty and i thought i would try it out. so far, it has not been bad.

i've already meant to women. >> it is not easy to make a good impression in a 60-second contradiction. -- country -- introduction. this man fails to do so. these women have high standards and they know what they want. " they really do have high expectations. it does not help that i am not from beijing and i do not know anyone here. due to my job, i have moved a lot in the last few years. that has made it hard to find a girlfriend. >> to knows? the woman of the streams might get on at the next stop. at least for these young people, the time they have to spend stuck in traffic is not wasted. if you do not have that bus ticket, the internet is the obvious choice when looking for the right partner. and tonight agencies, at a

welcome boost to their wallets comes out -- many soon discovered that this welcome boost to their wallets comes at a heavy price. >> all you see is a heavy veil of yellow fog. it is not fog, but at grid smoke from a thousand step -- smokestacks. welcome to one of the world's richest cities. rich in natural resources. it is normally off-limits to foreigners, unless they have a special permit. 175,000 people live here, within the arctic circle. the smokestacks are visible everywhere. practically everything here belongs to one of russia's largest and wealthiest raw materials companies. that includes this smelter. it produces pure copper. they did more than $5 billion

last year. most of the money flows to moscow. a breathing apparatus is mandatory here at the plant. it is one of the city's biggest polluters. even though the chief engineer points out the bright side. >> there are detrimental a facts. we have markedly reduced with new technologies. >> it is hard to imagine that things are worse here in the past. the emissions from the smoke stacks pollute the air with heavy metals, formaldehyde, and sulfur dioxide. the official statistics are devastating. more than 5,000 tons of pollutants are released into the air every day, a world record.

hardly anything grows from the ground anymore. let alone in the forest. it was not destroyed by fire, but by acid rain. apocalyptic images, it is considered one of the world's most 10 the most contaminated places. to live here, is to put your life at risk. >> she cannot -- he can not go to the playground with his parents dairy often. his bronchial passages are damaged. the young family went outdoors because the wind is favorable and that means the air is relatively clear. the emphasis is on relatively. >> due to the industrial emissions, we have to stay home

a lot, especially in the winter or when the acid rain comes. if you are lucky, there are merit -- there may be a clear summer day. >> of life and a constant state of emergency. we doing nikolai as they take a bus to town. they moved a few kilometers out for the sake of the boy. they live here because they could not earn as much money anywhere else. niccolite is a metalworker and 1000 euros a month is a dream of salary. he accepts the city's abysmal quality of life. his son's illness worrisome. -- worries him. >> the whole city grew up around this factory. that is why this bears the name.

it once did the city hope. as long as this factory exists, the city will exist, too. >> hope. if the no longer had worked here, we would not find anywhere -- anything anywhere else would decent pay. >> no matter who we ask, it is money that keeps people in the city. we take an elevator 1,400 meters below the earth's surface down to where the city's treasures lie hidden. a format camera teams are seldom permitted to film here and we are taken to a showcase mine shaft. one of the world's biggest nickel deposits is in the ground. cobalt, palladium, and platinum are also mined here. special drills pour into the stone.

vladimir is quite open about something we may not have been supposed to hear. >> of course, this is our most modern shaft. in the other shops, the technology is completely out of date, everything is done by hand. >> a total of 300 kilometers of tunnels. a special vehicle takes us through a seemingly endless labyrinth. the first mine shafts were done by prisoners -- prisoners. these days, and number of german companies supply technology and equipment. rich ore leaves the ground almost around-the-clock. almost everyone we encountered wants to leave the city as soon as possible.

those who stayed die young. hardly anyone lives beyond 60. many died of lung cancer or other cancers. a few years ago, there were plans to evacuate the city and leave only the factories. the plans were abandoned. the fruit and vegetables at the market are grown far away. that is reflected in the price. a mellon for tend euros. that is on special offer. -- a melon for 10 euros. but they did not want to buy local produce. they want to stay a maximum of five or 10 years. then they hope that their son will never return. >> we would like to tickle your tastebuds with another global snack. we have already introduced u2 no

fuss foods from all over the planet. we keep looking for these down to earth delicacies. this week, we had to london. >> every morning, he takes a few eels. the water cooks them in his later used for the sauce that goes with the specialty. this is an institution. it is also a popular neighborhood hangout and has been since the 19th century. in the old days, the place was forgotten by dockworkers. they wanted hearty fare to fuel their hard work. one ingredient has always been essential. >> salt, flour, that is it.

>> of flour and water, little else is used for the dough. we asked him how many pies he makes a day. >> a couple hundred. his pies do not contain preservatives or artificial ingredients, just british ground beef and water. >> this is the most traditional meal you can have in the extent of london. not a burger, not a currie, at this. that is that. my great-grandfather was the very first man to do it. very proud. >> they have been making pies

>> the service is great. >> she gets a five euros for every a badge of the fact she turns over. what becomes of all that is used cooking fats? it is turned into energy. a truck picks up the oil from the restaurant and kitchens and brings it to a purification plant. the containers are moved into a heated room to keep the oil from getting cold and solidifying. if it is heated to above 60 degrees celsius, it states fluid overnight. before the fat can be used to generate energy, it has to be filtered.

earlier, at the used cooking fat would be poured down drains and called up the pipes. now the plant processes 15 tons of it a day. when it is a peak season, that number grows. once they are emptied, they return to the kitchens they came from. processing that much cooking fat is no easy job, especially for those sensitive to odors. >> it took a while to get used to it because the smell is really intense. >> its is really about growing accustomed to it. these days, i no longer notice the small. but my wife certainly does. >> this engineer came up with the idea to turn cooking fat into electricity. he wanted to help the

environment. the engine during the plant would normally take diesel, but it is fed with cooking fat now and it generates zero emissions. the engine cost half a million euros trade two more years, and the waste water company will have recouped the investment. >> the engine is not specifically called fitted to run and cooking fat. the secret is that the cooking fat is processed and it really does turn into fuel. it works in the engine without any problems. the plant generates enough electricity to power at 3000 homes. >> the biggest change at the waste water treatment plant is that we produce our own energy now. we do not have power shortages anymore. we can run the entire facility with the biodiesel.

>> he takes advantage of any opportunity to produce environmentally friendly energy. he even save the waste that is left over from the water treatment. that sludge is dried out using the heat from the engine. it turns into valuable fuel for local companies. >> the biggest advantage to drying out the leftover waste is that it shrinks. there is less of it. there is only a third of what is usually left over when you press fight waste water. the end product has a very high heating value. it is ideal for the cement industry. >> the people have long since gone used to the idea of collecting fat for energy. >> i use very little fat when i cook. i take what has been used to the collection center. >> today, she has guests and she

is making a big dinner. there will be plenty of used cooking fat left over to power the town. >> that is all we have time for. thank you for watching. we hope you will to it again the same time next week. -- tune in again the same time next week.
