oh, franklin, i already knows. welcome to tech told me about hackers and paralyzed me turner society's computers than oh, sure you and governments that go crazy for your data. we explain how these technologies work. how many can we go some for, and that's how they can also go terribly watch it now new to ah ah ah, welcome to global 3000 new life in the step villages in tanzania,

a replanting forests, and encouraging the rains to return precious and scarce in many regions of the world, fresh water is in short supply. what's the solution? in lebanon to water supplies, a dwindling but women stepping in and planting the ants. an unforgettable image, a column of smoke rises over the harbor of lebanon's capital bay roots. 2750 tons of ammonium nitrate at fertilizer exploded here on the 4th of august 2020 devastating swathes of the city. 200 people died and there was an estimated 13000000000 euros in damages, too much for crisis rock to lebanon. yet once upon a time, the country was booming, they route was a cosmopolitan and sophisticated city. but then in 1975 of war broke out.

political and religious groups battled for supremacy tearing the country apart. the war only ended in 1990 to day, much of the population lives in poverty. the infrastructure has largely collapsed, including waste collection. the local currency has lost 90 percent of its value. many struggle to afford the very basics, food and heating and gas. and it's really tough for the many refugees here too. but there are some projects offering hope it looks like a game, and it really is child's place since every throw is the goal. the small brown balls that these women are throwing into the big car valley are so called seed bombs. the bulls contain plant thieves. an outer layer of clay protects them from birth and road, and when it rains,

the bulls soak up water and then the plants grow all by themselves. the plato plateau of the because valley used to be famous for its largest cedar forests. a cedar tree even ended up on the country's flag. however, growing settlements and uncontrolled deforestation have meant that there is hardly anything left of the original forests explains a coordinator from the aid organizations or lum. l. a. d. c. and i've had a collateral fellow. we never used to think about the importance of trees up until we might sit under a tree in the shade. but we never asked ourselves where did it come from? 100 a saw he planted it. i had a hand on the other day and it was only 3 this project and we realized how much effort it is to re green a country hall. i ran lower it off led to the bay re forrester. lebanon is just one goal of salam. the work here is also supposed to bring people together who otherwise have little to do with each other, says, but to ebara him who fled from her syrian homeland to neighboring lebanon. 10 years

ago. a cave thought venza the women. her all work wonderfully together. and yet whether they come from syria, palestine or lebanon, about horn, we originally met through the project. what now were all like sisters in the home button instead alone? we laughed together. we tell jokes, it makes the work easier men and then the said, some of the women live in informal settlements. others have a solid roof over their heads, like between abraham from syria. nevertheless, she says live in lebanon is not easy for her. her husband is unemployed and her daughter regularly needs expensive medication. without the 8th us dollars she receives for each day's work, the family would have no income hits and no it has sydel. and my little project is more than just a job that brings and money her mother had i had father, i wouldn't know that it lets me do something good for nature and the environment he

did be, or i'm fear that bobby and i now live in lebanon. it's become my new home that to that and not, not who will what? and i want to serve this home area better than i the feet of at the north. any. or even if it's only a small contribution, middlefield believe, ah, lebanon was once called the switzerland of the middle east because of its well. in the meantime, however, almost 80 percent of its nearly 7000000 inhabitants live in poverty. ah, the situation is particularly dire for them. more than one point. 5000000 refugees, most of whom come from syria. their high number has led to mounting social tensions in the country. ah, susan unclear has experienced it herself. she feeds her family of 5 with the money from the reforestation project. she's lebanese, but her husband is palestinian. their children are therefore considered foreigners via on pretty annabel admin and on there. so much discrimination in our country

here. but so hon. even my children phillips and laughable because of that, danny and father are not allowed to go to the local school issue or issue mcnelty. i wish my children could grow up like any normal lebanese child on an. instead, they are excluded from many things. and my husband isn't allowed to take certain jobs in it, just because he's palestinian nor nationality does not play any role in the trees for lebanon initiative. the only condition for participants is that they do not have another means of income. because the project especially wants to help those most in need. to day the women are making seed bombs for wild time and sisters. in addition to reforestation, the product also wants to plant crops that can lace her be harvested after sifting the soil, the women add the clay that will later form the hard outer layer of the seed bowls

. when both are mixed, the seeds go in everything is then mixed with water and need it. it's a sociable process. the group then sits together and shapes the individual seed balls . ah. when the balls are finished, they need to dry in the sun for at least a day and then they're ready and new life can be created from them in alarm. bizarre. so i'm reinforcing lebanon muscle. it's amazing observation of my children will. thank me, though benefit from it also to hillary and an even when none of us are here any more, i've done something good for the future of our world here. and i'm sure of you. for

to day the women have finished their work. the project aim is to release a total of $600000.00 seed films. by the time the reforestation project ends in august next year, it would go a long way towards bringing back the country's famous trees. drinking washing, cooking industrial production farming without water. we humans are lost yet, according to the un, as many as 2300000000 people live in areas docked by water shortages. that's around 30 percent of the global population. by mid century, our planet could well have a population of 10000000000, with an accompanying rise in the demand for water. but water supplies are already dwindling. many natural reservoirs are already over used or have been contaminated

with sewage. where on the brink of a global water crisis, could our oceans offer a solution? kate down was the 1st major city to risk running out of water. but it's not going to be the last jakarta, london. they jing tokyo could all face their own day 0 in the coming decades. most of the water, at least food for month, year are experiencing some will to stress off or disgusting. the gap between demand and supply your water is narrowing down. but how can that be? our blue planet is a wash with water. more than 1000000000 trillion leaders to be precise. the problem is that 97 percent of the earth's water is salty and most of the fresh water is frozen in ice caps. in less than one percent of the earth's water is

drinkable that makes one solution, especially promising salad nation. we sell a nation. these hallucination desalination seems like a pretty straightforward solution. you take that undrinkable, salt water, remove the salt, and end up with an unlimited supply of fresh water. so why are we not building more desalination plants? me? thermal desalination uses heat. sauce boiling point is a lot higher than waters. so if you boil salt water, only fresh water will evaporate, leaving all the salt behind membrane desalination uses pressure. salt water here, colored in red for clarity, is pressed through a membrane that is only partially permeable. fresh water can pass through here, colored and blue,

but the salt is trapped on the other side. the technology didn't improve much until the 19th century when industrialization and population growth encouraged more research. population growth is the main driver far increase in water scares. and soon, another factor could make desalination even more crucial global warming. as the climate warms, more water will evaporate. and as aristotle noticed more vapor equals more clouds equals more rain. but that rain won't fall evenly. this map shows how precipitation will change as the climate heat up. regions in purple will get more rain, those in orange less. now compare it with this other map. these red dots indicate areas that are already experiencing water scarcity today. dry

areas like hal fornia and the middle east will have even less rainfall. other countries, like india, will have more rain in the monsoon season, but less in the dry season when people need it most. this will make desalination even more popular. with boiling, billions of leaders of water takes a lot of energy. them at least the availability of, of oil and especially fossil fuels makes the thermal process is cheaper. but for other types it could be, i think, 25 or 30 times more expensive. but that energy doesn't have to come from fossil fuels. a start up in berlin has a sustainable alternative. the water come basically from the bowl, sorry for the system. and after that is gone through the boost upon with 14,

by the water is price through the membrane. and he is in it is water with green energy. that's the key to the company success. this is one of their plants can kenya the solar panels, keep the cost of water low in villages like this, where electricity is not available. i get the water for free. we get the electricity from the solar and wind for free. so we can now produce 1000 meter for $0.50. this price is actually competitive to clean water from the river or from the ball. but there's another problem. what do you do with this water that's left behind? so we thought of this, so look out of the water to produce fresh water. but now the salt is still

contained within no substance, but it's just a smaller volume. so it's most ot ah, this water is called brine a be over let what we produce more brine than we produce nice adding it to what you put your bike with this coming out of the discipline. you'll discharging on the sideline wooten in and as it flows out, it will sink because it's more dense. 70 and the temperature can also deplete the oxygen available. and this is what's causing actually the organisms more damage, just a lack of oxygen that basically southgate bryan can also contain chemicals harmful to see life. but what is this waste could become a resource tomatoes, seaweed, and certain fish can tolerate high salinity. morial light uses brian to cultivate

them in tubs like this. at the moment here, the technologies auto in a boat of far brine management. but those are on a very small scale. the challenge is that all we can transform those that small scale technologies into a large scale operation. desalination is not a magic formula. the process must become more efficient before low income countries can afford it. desalination plants must convert from fossil fuels to renewable energy, to limit emissions. and the whole industry needs to come up with a plan to deal with this bry. what facilities like this are already a lifeline for many communities. movie. today, cape town is doing a lot better, and the dam is full in. the city was rushing to build desalination plants to avoid daisy row. but the solution wasn't desalination or any other technology. people

became water wise, they radically changed their water use and they valued water for the essential and irreplaceable substance that it is and will stay with the topic of water shortages and climate change is causing drought in many countries like tanzania, but in the region of russia are reported to carry yuki witnessed something extraordinary here in anger, a village in northern tanzania. hardly anyone has a tv. that's why linda mill limbo brings a small mobile cinema with her food. she was here a few months ago on behalf of the lead foundation m. genie and conservation organization. oh mama was another girl, but it won't let me grab a spell. i want to show a film about see how here today i'm buy cuz he hi means living tree stump loyalty

mexic. we'll start with announcements in the village, and later on the evening we will show the found blame led you on it, not lasting in mexico. but where is every one? it's still early afternoon and the villagers are in the fields. digging in the bone dry earth holes in the earth as far as the i can see, it seems like all 7000 residents are out and about what's going on, digging here because of another movie presented by linda ma limbo and the lead foundation. it was called just dig it, john mooney remembers it well as he digs a trench and fills it with grass sieve little combo parmesan get the film taught me that you can do something about the dryness and drought of recent years. while

cadell aqua, we can till the land is in create water basins via my glass, which we fill with seeds to help the fields recover. but in the canal coil mazda mazda in recent years, fields here have continued to fall victim to desert vacation. the persistent drought is a consequence of climate change. what can anyone really fight back about when it's 5 pm and linda malone bos colleague makes an announcement that the film screening is taking place that evening? no, no, no, we don't want another one. yeah. it's a welcome change for the villagers. they only get to see a film every few months. the children are excited to see what's coming warm. ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, yes. now the final touches linda moline bow has been doing this for 3 years.

3 years in em, enough on the dome explains how to protect your land from drought, africa. people have cut down their trees many times in recent years. land became barren and the harvest cells got worse. all those locals. now we want to show people how to reclaim that moisture so that their yields increasing and they have enough pasture to feed their families even on while i shall room. it's fine. the show time it starts with j monte, a very popular comedian in tanzania. why he's riding a bicycle through the fields is a mystery. what's more important is what he hears. so

i don't know why. well why we're talking about any new mama. i'm not kidding in you. when i got, i mean to niggle good talk on gama. i see from bonnie up ne, in italy mans and humans. i read not owned on known him to look at that. i got i'm not about i'm, you can reach any. i'm back in one. yes. i . every one in anger will go once rain and the film as well. received people here become familiar with drought over the past few years. what it means to be thirsty all day long. the film showed the villagers that small

shrubs or tree stumps can grow into large trees. if given a chance. first viable plants are selected. next their prune so that only the strongest shoots remain than the trees must be marked for every one to see. and importantly, the plants must be protected from hungry cattle. according to the campaign, this method has managed to save over 9000000 trees in tanzania, a re greening measure of this magnitude has an impact on the local weather and can also bring rain this means the country will cool down and crop yields will improve at least in theory, in anger rica, it's still a dream though the last few months have seen 30 percent less precipitation than in

previous years. which is one reason why they're digging the rain basins. according to the campaign, there were now over 200000 such basins in tanzania and kenya. and all of this just because people saw a movie. in reality, people here earned one year of 50 per basin. diligent workers like dina, hosea can manage 5 a day. weekend in iman for wednesday, if we make money digging now and i had to vidalia my, then you grew up later when the grass has grown. folk said we will benefit both our cattle and to us will be in because we save ourselves the trouble of carrying food to the cattle neighbor. my then home was i was as david and i ruined my then one week we'll go, we'll do that. if we employ these practices, they won't help us take care of our livestock failure. not to say, dear bud in the fool. rainwater normally evaporates on the dry soil, but now it can collect in the basins. miss gibbs, the water,

more time to seep into the soil. and this allows vegetation to grow, not only inside the basins, but also all around them. this re grinning program is in full swing and gaining in popularity. ready strategies like this one have an impact on the global climate and could even help to slow down global warming. and the people of anger are doing their part. ah, how did people around the world live for this week's global living room? sweet. go to our mania. ah that is hello. come on im ethic. the soon the last these are my son's was the last a mom and my mother had sickness with a pardon. my name is annie. man. ok,

i'm any rocky armenian was a joseph of i in 2004. we fled from iraq to armenia because of the war. a guy i asked them, ah, at us you found this dull, was the 1st thing i grabbed? whatever the my father said, it was too big to take with us, but i said, i wouldn't go without it. may i ask? i got the door when i was to, we got on a trip in armenia to stay with that a. i'm 46 now, said the dolls fuzzy fold that acre with them. ah ha, monitors get these caps out and make us some tea. ch, are you familiar home? i'm the new ah, make us by with that we always string tea from these cats. i isde kindness. they typical tea cups in iraq, never after then we use them with sources like the j by juggling the to make to re, uh, once the hood is boiling, we put in the t let it was m a turn off the heat. let it sit for

a couple of minutes and then pour it into the cups. will gander the mirror? goulburg did obviously j v because it has to be sweet said huh. vega thought i let you know then it's her effect. pity his duty of stealing che you have to serve di and very beautiful cap as near the more you respect your guess the more expensive the cup has gone down gonna pump it in as well. i see it, honey, this is our son's title. he got it for his birthday, we call it cuts that out of he did that without the nora ariana godzilla. vienna said look, if you press on this bus, it peasy ganette. i am aquarium measures. we've had this fish tank much longer than the turtle. an
