hello and welcome to global 3000. need to rewind and villager who designed his own hydroelectric land. emergency art, creating from around the world can help. and welcome to the green school, how privileged kids learn about sustainability. the european union runs the largest emissions trading scheme in the world.

the idea is to use market forces to make it more expensive for companies to pollute. the hope is that they would then invest in more green technology and produce pollution. -- reduce pollution. it remains cheaper for companies to keep polluting than to actually cut down on their co2 emissions. still, the money is making a different elsewhere. authorities in rwanda are convinced that offering projects that comply with emissions standards can help development. we caught up with a man who got a financial boost he needed at just the right moment. he put his ideas into practice and delivered green energy to a whole community. click for people in this village, this 60-year-old is a hero. he brought electricity to the small hamlet three months ago

when he supervised the building of a small hydroelectric power facility. now he has come back to check that everything is working properly. he construct the plant with men from the village. here at the water's source is where it all began. >> at the start, my wife thought i was crazy. enables all -- the neighbors all told her, divorced that guy. he has lost his mind. but then they saw i could earn money from hydroelectric power. our neighbors suddenly came to me and wanted to buy electricity. >> the most amazing thing about the story is that he taught himself how to build the generator to convert water power into electricity. this self-taught engineer spent years turning -- learning about the technology so he could give nine children electric light in their home village.

>> we were poor, and we wanted to earn money and get electricity for our village. we had nothing other than diesel generators and petroleum. so i thought, why shouldn't we use the power of water. that could make our lives easier. >> 200 households will now enjoy electricity. that amounts to a revolution in a remote region beyond the electricity grid where people live from what they grow in fields or gather from the forest. small-scale initiatives need support if they are to succeed. and the rwandan ministry of the environment helps his project to become reality. he is advice on how to create hydropower plant in villages. -- he is advised on how to create hydropower plants in villages. >> we have to protect the

environment. to build something like a hydropower plant, we are -- that is why we are here for this kind of project. we are here to see if this project that he has built for his village can get carbon credits. there is a way to get carbon credit to finance this project. >> in the past, there were no small businesses in the villages. now young people like this one see a future here. at 20, he has opened up a barbershop. >> i used to use diesel generators, but that was loud and expensive. and it also stank. everything is better using hydropower.

sometimes customers even have to stand in line to get in. >> the land of a thousand hills, as rwanda is known, has been partially divorce it. he has been -- has been partially the forest it. he has been traveling around the country to see what can be improved. one of his success stories is this village outside the rwandan capital of kigali. many of the residents are women who have narrowly escaped at think genocide 20 years ago. the war left a village full of widows and orphans. he introduced them to the wonder bag. it is an insulated cooking bag that means the man can cook in the morning and put the pots in the bag. it conserves heat, so the food continues to simmer. when she returns home from the field at midday, lunch is ready.

it saves both work and resources. >> it used to be very difficult to find firewood. with the wonder bag, we save a lot of energy. now i can cook for a week with the same amount of wood i use in a single day. that means i can make something warm for the children every day. >> the average price of a wonder bag is 25 u.s. dollars. it is well beyond these women's mean -- means. he and the ministry are trying to get rwandan villages to save enough energy for the country to be able to sell carbon emission credits. >> it helps to cut down the price, you know. these wonder bags are very expensive for these people to afford.

but through carbon finance, it can subsidize these wonder bags so that people can get them free of charge. >> he is looking forward to returning to his home village, about 300 kilometers away. he also has a dream for the whole of rwanda. >> i am old now. i would like to teach the next generation how to build small hydroelectric power plants. i would like them to continue my work and use all of the water power that rwanda has at its disposal. >> before he sets off back home, he takes one last look, and one last picture of the power plant. that way, he can show other villages how easily the facility works. >> when the global financial crisis -- crisis hit with its

full force in 2009, it sent high a demand for diamonds. the global diamond trade is back into the double digits. desperate for the one fine i can secure food for days, weeks, or even months, many sift through the rubble of abandoned mines. there are those who try to survive by finding the raw materials for the insignia of the rich. >> the indian state of module per -- -- of madja pradesh. there are no jewelry shops in the street, but it is a center for smuggling and black market activities. meet the human rights activist. he works for the byronic's trust and deli full -- in delhi.

one of the focuses is the people who work in the indian diamond mines. he is a regular visitor to the diamond mining areas located some 20 kilometers outside prana. a lot of the legal -- illegal mining goes on here. the workers here are normally farmers and day laborers. they try to bolster their monthly income by earning a few rupees here and there. now in the dog days of summer, the river is drive. and mining requires a lot of water. >> usually, the workers collect soil and whatever else they can find from the pit act there. a mix it with water and stamp it with their feet. gravel and diamond sing to the bottom because they are the heaviest. the workers then skim off the upper layers of water and soil with their hands.

they pick up everything left over and dry it in the sun. click c tells us that this man has been mining for diamonds for more than six years, despite his age. he says it is enough to get by on. and in the past, he has found some decent sized diamonds. >> he says with the diamonds among the stones, the workers do not have to look too long. you see them immediately, because they gleam in them -- in the light. >> but there is nothing gleaming here today. these young people, too, are hunting for diamonds, breaking rocks, even though it is more than 40 degrees celsius in the shade. the youngest of them is 13. his brothers say they are 16 and 21.

the girl does not want to say how old she is. >> workers often have dust in their lungs. it clogs them up and they have serious trouble breeding. unfortunate -- they have serious trouble breathing. unfortunately, they have no health coverage. doing this work without breathing masks and protective gear is dangerous. i was at a funeral recently. one of the workers had died of silicosis. >> he has achieved some small triumphs in his fight for improved working conditions for these people. the national human rights commission in india is demanding that the health of diamond mine workers be better protected. but that is not enough for him. he estimates that up to 70% of the diamonds here are extracted illegally, often by children.

>> at the root of all of these problems is corruption. the government supports a lot of good projects. but the help never gets to those who need it. the government needs to come up with a plan to give children here in education, so they can get a jeep -- a decent job later on and lead a good life. >> he says that the problem is the lack of schools in the region. local families have no choice but to send their children to work in the diamond fields. they need the money to feed their younger siblings. >> it is difficult for these families to break the cycle of poverty. in fact, the u.n. children's agency unicef estimates there are some 150 million children who have to work worldwide.

many have no option but to work. many are against making child labor illegal, but they want to see better working conditions. in africa, many children find themselves orphaned by the aids epidemic. if they're lucky, their extended family takes them in. but the trauma of losing their parents stays with them. we caught up with young artists in mombasa who are working with kids who have lost their parents. >> most of these children's parents have died of aids. this is one of 15 international artists who come to kenya hoping to use their talents to help such kids. the artist hails from south korea, the united states, and britain. they are holding workshops. the point is not just to teach the children painting, but also to get them to express their dreams and their hopes. it is the first time many of these orphans have ever held a paintbrush.

the artists are working in three villages near mama said. -- mombasa. they have been working with the project since 2011. >> we are hoping to get them to express themselves. when i look at the children, it is very touching. one kid has hiv and he -- his portrait looks different from other students. >> just close your eyes first. yes, close your eyes. think of you, your self in the future. open your eyes. imagine it that way, when you close your eyes. now draw your hopes.

but i would like to be a veterinarian because i like animals. >> i painted a plane. i love the sky, the moon and the sun. >> a farm. >> the course gives the children a break from the harsh realities of life here. it teaches them how to be independent. >> i don't think this workshop will change their entire life right away. but it will definitely influence them to think differently and

help them to have imaginations. >> the organizers hope that interacting with the artists will allow the orphans to get a better start in life here in their villages. >> and who knows? may be one of them will one day be able to live off of their art. this man in guatemala has managed to live his dream. to him, a good painting is a message without words. he gives us his take on globalization. >> my name is oscar eduardo. i live in july and i'm 62. -- in co-op and i'm 62. ♪

of course, tourists do not come in and buy three of my paintings at once. usually, only one, but i get by. and i would rather live from my heart than do other things. -- my art than do other things. >> i've heard of it, but i don't know anything concrete. >> in terms of expenses, we sometimes have more money. sometimes we have less.

but my wife and kids and i all help each other out. i don't think there is any reason to worry, and i hope a lot of people feel that way. we don't worry. life is good. >> a little bit of everything. health, money, love, that is my personal idea. no idea how others see things. >> i like well-done meat. >> talking. i enjoy talking with young people. and i've also got a regular group that i meet with to chew the fat. that is what i do in my free time. but i see my art as the future

-- >> i see my art as the future. recently i read somewhere that when i die, so will my simplistic painting. but i don't believe that. i think successive generations will preserve my style. >> indonesia's island of bali today is almost solely known as a tourist paradise. when you mention the name to many who have been there, they start to wax lyrical about the amazing sunset and wonderful beaches. once a proud kingdom, large parts of barley -- of bali have become challenges with waste and water management. the graduates of this international private school are all about sustainable living.

click he's doing his best -- >> he is doing his best to save the planet, or at least one part of it. this pond. he is learning about environmental preservation and sustainability. on the agenda today, how frogs survive in ponds. this is the green school on the indonesian island of bali. the paradise is located around one quarter of an hour south of this small city. there is no central school building. instead, individual classrooms are spread across and eight hector campus. some of the lessons, for instance in green studies, take place outdoors. >> originally, it was growing like this. should we do just rose or a clump? -- rows or a clump?

i took the role of client. i told them, this is my pond i want to clean up. and i gave them some demands. we've been studying the pond for two weeks. we learned that the frogs are dying in here because there is no escape route. >> this gravel will allow the frogs to reach land. >> it's really fun having classrooms right next to nature. you can just look out your wall and nature is right there. >> solar panels provide 80% of the school's power. the rest comes from a biogas generator that is fueled by composting toilets. each class has its own garden and supplies the school canteen with food. on today's menu is fresh tomato salad.

along with ecological subjects, the school also offers standard courses in math, grammar, philosophy, or physics. the students come from almost 40 different countries. the curriculum is internationally certified. >> right now in science class, we are doing a specific sort of lab -- what should i call it? >> a design engineering project. >> we are doing a project where we have to build a roller coaster made out of rattan and bamboo. we have to build it and make it flow. >> they have to take something from the natural environment, from the jungle, and construct from scratch a roller coaster that shows all of the different point specifics of motion along the way. they have time and states to be created with the bamboo, with the raton, with each other and the whole group dynamic piece. it is a much more thematic

approach to teaching than you would get in each additional course. >> it is recess, a chance to check out the local surroundings. here, concrete takes the place of bamboo. bali's environment has suffered greatly from unbridled tourism and demanding growth of the island's population. new settlements and streets have been built where palm trees used to grow. sometimes religious rituals are all that remained of the old bali. bali lacks an efficient waste disposal system. garbage is simply burned. back at the green school. after recess, it's time for math.

but gap -- class begins with an israeli folk dance. ♪ >> at the green school, the emphasis is on combining practical skills with an awareness of the importance of our and merriment. -- of our environment. >> there are some in the kinesthetic aspects that i can take. moving forward, moving backward, keeping a beat, stepping to the right or the left. all our skills of our human body. it is an education for human beings. not for universities. >> lunchtime. the kids are enjoying some

balinese dishes, italian pasta, and of course, fresh tomatoes. the food is served in wicker baskets lined with banana leaves. they don't need to be washed and that saves water. tuition fees are 10,000 euros a year. balinese families cannot afford that, so the green school remains an oasis for the children of wealthy foreigners. still, maybe one day they will share the ecological knowledge they have learned here back in their home countries. >> if you would like to see any of these reports again, or to join our global could -- global discussion, you can find us online. that was it for this week. thanks for watching. from the whole team here in berlin, bye-bye. captioned by the national captioning institute --www.ncicap.org--gg99ññwççñmw
