in touch, follow us. ah, ah ah ah, ah, ah, welcome to global 3000. as fishes, a fiddle. what flow my linda's secret when it comes to longevity?

power from the deep could all oceans satiate our future energy meets and droughts in kenya, when it comes to fighting climate change and to creativity. no rain for months kenya is suffering from historic levels of drought. the soils are too dry to cultivate grain or vegetables. cattle lie dead in the arid step plans. 2000000 people are at risk of starvation in kenya says germinate, organization, very toner, heifer to blame global warming, the over exploitation of natural resources and widespread deforestation. aid is urgently needed, but so our ideas, ideas for how to make it possible to survive in kenya's dry regions in the future.

our reporter, tobii imagine tyler went to kenya to find out more. the music and festive atmosphere soon attract the crowd. this safe pony theatre group is performing to day in vermani in southern kenya. the play is about every day hardship, environmental issues and climate change. it's called me on go that means decades in swahili or google. holla, go home to do it sweeps through the last 40 years starting in 1981 when nature here was still intact. but years of deforestation have followed to feed the charcoal industry. what will things look like in the future? my group manager, david kalu, me, takes the audience on a journey. where did we go wrong? he asks, what can we do differently to ensure the next 10 years will be better?

the story ends in the year 2031. it just build people on the on that mirror for them to see that this is exactly what i'm doing. so what can i do? so via the when it is, it's just a reflection of your life. so from the reflection you can understand noise like a mirror if you hover something a dead on your face, then it's time for you know, to try to clear that. so this is exactly what we're doing. save bonnie is the activists know people here are faced with existential problems. only 3 months ago, 40 year old shock, how much a lee were settled in this village. a 2 hour drive from mombasa with his 50 cattle, but now his herd is dying of starvation. he used to live in a village some 35 kilometers away until drought forced him to leave. but the situation is no better here. her grandma, my grandma, i have to buy the calves milk because their mothers have no milk to suckle them one

back while you're in. yeah, they don't even have the strength to stand up. they don't have the energy to graze on the field. sparse green chuck, i'm on to lee were has to help them on today. his assisted by some of david kalu miss act is currently touring the area. i am a single oh, we're here because we're working on a program when we went on it. mostly what we're doing is looking into community resilience towards climate change. as we can see that all the way that part of the change. you can see that the claim it is not as it was some years book for one, the dry season is getting longer. sometimes it doesn't rain for months on end. now the theater group has invited locals to a workshop to talk about their troubles. the team hopes participants can pass on what they learn here to other villages working year from now. one of them is 68

year old killough work. he told me. oh gosh, no jumbo lamita's. every one plan to trainees. oh god, what will be good to the environment? will not, she doubt all your living conditions will be better suited to collect? will keep on burke will keep people healthier, no joy yourself. and according to your home, say, the retired civil servant has planted a range of trees from password enough to blue gum and named trees. they provide shade and protect the ground from drawing out. he also keeps bees. he has 18 hives, and earns the equivalent of $1600.00 a year that allows him to pay for his daughter's schooling. and soon he hopes for her university education to one of his 2 wives and the mother of his 3 sons. kabibi kalauia had no such luck in if the were the world i fuller were real and i didn't attend school here because my

parents weren't able to pay for my education. i live live or going on with those who are one i gave. so i decided to get married vinegar, liquor more for new, a fate shared by most women around here. poverty is widespread. locals fell trees to clear the land for agriculture, but that makes the ground even dryer. so harvests are poor. they end up resorting to selling charcoal, but that's made from trees. so they locked in a vicious circle in the workshops, facilitated by parent n g o safe? kenya, the safe pony team helps locals develop alternatives. we believe that is that people who festival started the problem and is the people who can solve the own problem. she to us is asked know, coming to just make them realize this is where we went wrong. and then after there

is them not to look at the solutions and howton with ours is all you to facilitate these discussions? facilitator them coming together? that is what we are doing much, but the solution is coming plating from the people. after 2 months of consultations and conversations, the theater groups latest tour is drawing to a close. now. the safe kenya in g o aims to boost people's resilience amid the climate crisis and inspire them to find solutions. it's safe, plenty theater group is based in mombasa, and financed by the international climate initiatives, small grants program. they'll continue to work with locals here for the next 2 years. wow. the audience have got the message, renew them, or maybe not live with all my thing given. i have learned that when we manufacture charcoal, it has many a negative effects on our landed on my bad. i'm a co worker because i don't know that by the legal monitor,

other things will change because there will be no more cutting down of trees. and if people get tree seedlings, they will plant them and the current situation will improve. oh, my god, he hardly w killough work. he to me is also among the audience. his tree planting has often been marked by his neighbors. now he's been vindicated, though, in fact, his desperate since the activists were last here, the drought has killed all of his bees. and the seedlings were his new plans have dried up. still his determined to keep planting new trees and hopes more villagers will follow his lead. it's the only way they can secure their future. blue water is life. it covers 71 percent of our planet surface and is in perpetual movement.

ocean currents in particular have huge potential as energy generators, as much as a 1000 nuclear power stations. tremendous powers brought forth every day due to the moon. it acts like a magnates pulling the water of our oceans towards it, creating a wave peak or high, tight. on the other side of the earth, a similar wave peak is created by centrifugal force. over the course of a day the earth rotates beneath these 2 high tide, peaks in between them is ab tight. these are the tides of the seas. could tidal power be the clean climate neutral answer to our energy needs? off the coast of scotland, you could witness this window by ins being put into the water. they're called tidal toby. they sit on the sea floor and harness the energy in the moving water that comes in and goes out with the tides fell. car just

cannot sitting there and waiting to be used. the potential is huge. it's estimated that we could practically capture enough title, energy to power all home from the united states, twice over my research with climate change shows. we need this energy now. yes, at the moment, all the energy we get from existing title power plants worldwide can power less than 400000 homes. so how does title bow walk exactly? and why isn't it every way it would title power? there's one word that comes up a lot, predictable, predictable, predictability. tides are predictable. they come in, they go out and they've been doing this the same way since the moon was bond. so at the dial stick adobe in the water as it flows in or out. and viola you can make electricity with the same, it's bullet window binds you moving water mix the turbine spin. this powers, the gearbox on a generator which turn the mechanical energy into electricity. water incidentally

is over $800.00 times downfield, an air which means the time turbines need to be studio, but they can be smaller and slower and still individually produce more power than wind turbine. so far so good. then back the titles from card predictability, wind starts and stops blowing somewhat randomly, and the sun isn't always out. so these renewables can be difficult to integrate into the grid tides, as we know, i really, really predictable and consistent. so if batteries are charged, when tides are flowing, we could use those batteries each time there's no movement and repeat at regular intervals. with tides to mean ways to extract power exist, once called title stream and the other title range. let's talk about titled range power. that takes advantage of the difference between the high and the low tide, which can go up to 12 meters. this work by building a dam across the region where the sea water meets the land. the shape of these bays

or estuaries magnifies the difference between the high and low tide. how it actually works is the gates of the down offers shut until the difference in the water level builds up to the highest point. and then the water is allowed to flow. and as it does so, a turbine below collects and converts all the delicious energy into electricity. many title plant can actually work when the water flows the other way too. which means they could work for between 18 and 22 hours every day. and this kind of title power has been along for decades. the oldest title rein generator lawrence was built in northern france in 1966. it costs around $1000000000.00 in today's money, which is cheaper than a comparable nuclear power plant. but higher than the cost of installing other renewables, but it's still going strong, producing enough power for a town of around $250000.00 inhabitants. and the electricity from lawrence is

actually cheaper than solar and nuclear. there are 4 other titles range plants running in south korea, russia, canada, and china. you can filter the range on anywhere, but it wouldn't be economical to put it somewhere where there's minimal title rents, top rates, and funding in canada, the northwest australian shelf, the northwest european shelf, the public guardian's shelf. but they're not all suitable to, for example, that may not be much grid connectivity or the populations may be quite low. so about, from geography the infrastructure to support title drains. plants just doesn't exist everywhere. and people have opposed the massive structures because they can be who left for the local environment, disturbing migratory fish, the composition of the soil and even taking space away from local communities. but things are changing for title drange power. a project commission in october 2021 in

wales dixie idea out of the $960.00 s and applies it to to be when environmental damage is much less acceptable, the design doesn't block of an entire b, but only uses a part of a lagoon. so the local ecology is protected and it's expected to generate even more power than the french plant. the proposal also includes space for aquaculture and sports for the area can remain a shared resource. 98 percent of title energy today comes from title range projects that together have a capacity of $520.00 megawatts, which is still a tiny, tiny fraction of consumption. but the other kind of total power generation could ship things up. the younger and sexier kind of the market dido stream power. it's showing more promise at the moment with its simpler devices that depend on under water currents caused by the tides. they vary in shape and design. the most common are breeze turbines, like wind turbines,

that can be set up in clusters in wind farms under water. a couple of research and development zones in the north of scotland supplied record breaking levels of clean energy to the u. k. grid this year. powering over $12000.00 homes for a year then there's an underwater kite that flies and a figure of 8. like the wind lifts the kite current and the water speed it up into and producing more energy. and then that off floating stream turbines, the most powerful of which was really the launch in scotland with an individual tobin capacity of 2 megawatts dead dead though to the sea floor. but the turbines remain close to the surface, which means the undersea works cheaper and they can be moved around. compared to wind of solar energy though. title has been slow for the reason you might have guessed. sadly, a lot of the solutions are really expensive because the industry,

so young with very small industry it's, you know, it doesn't have an established supply chain for manufacturing chain any time you were gonna operate. something under water has its own unique sets of engineering challenges. your standard wells lawyer, corrosion is going to be big problems. you're going to choose your materials. really carefully. bio falling is a really big issue where, you know, you put something, the water is things are going to want to grow on it and it's going to make it into a little mini regal habitat. the performance of the turbo deteriorates. you need to find when we are renting, that that's a huge operational costs, which is why most title stream generation project cluster in the globals not with financial support. the depth of technology at this stage exists china and south korea joining in but low income countries. like in the, i have been slow, a drop plans to try out. i do follow. but they could benefit when the cost of deployment begin to fall. charles, now as to bring down the price tag to,

to make sure that it is something that's commercially viable. and this is where things like sort of investments and govern government support. and so these can be extremely impactful. there is a number of proven concepts and there's a number of companies that have a technology ready. wiley, u. k, and canadian governments have been the biggest invest, doesn't tied to power. overall, grants and government investments have been flew with less than 0.0. 2 percent of annual investment engineers, boobs meeting title. and so it's been behind the cove in other ways to electricity from underwater. title turbines can cost up to $9.00 times that produced by turbines above the surface of the water, but the industry targets that life cycle costs good for the $0.10 per kilowatt hour by the end of the decade, which would be pretty cheap. but apart from cost, what actually happens when you put these turbines under water oceans are abundant with marine life. the structure of the la ron's project from earlier decimated the

populations of to 1st species. and like wind turbines that have been known to cause the lungs of bats flying past implored the pressure difference called by total barrages could have a similar effect on the internal organs of fish. but title stream projects are already more eco friendly. titled turbines turned quite slowly. so the idea of things getting chalked is, is, is going to be, you know, probably not going to have things getting hit yes. back and happens, especially at tip speeds. the big problem is not probably going to be collision. the problem is going to be displacement, that animals will avoid these areas and therefore not use these dairies to feed in . we've compared it to climate change and even by 2050. what you see is climate change is 10 times worse than taking the maximum amount out of tides. title has

other benefits too. while it's financial cost is still higher than other renewables . if net benefit could actually be higher when you consider things like it's predictable supply of clean energy to the grid. all the fact that stream projects don't visually affect beautiful sea view. so especially in cost, the long island nations title does have the power to play a significant role in getting the net 0 in a relatively less destructive way. the need of the hour is to make tighter power competitive. we need to understand such natural forces and live in harmony with nature. that's one key way to solve the huge global problems facing us and for us to live halsey contented lives. despite worsening global crises, more and more people are living ever longer lives. according to the un, there have never been so many 100 year olds. there are now more than half a 1000000 centenarians world wide, 5 so called blue zones. aki noah in japan. a korea in greece.

ali astra inside dina. costa rica nicola peninsula and loma linda in california. all have very high numbers of people living far longer than average. what's their secret? meat jane peel 103. james ho 82. and christine ho, 85, they're old and they're in great shape in loma linda, southern california, that's not unusual. oh oh, jean peel swears my healthy diet. she's never smoked and she's been te total. all her life. people are killing themselves where they're eating pep, their or their lifestyle is killing them. she's a member of the 7th day adventist church,

a protestant denomination. it's members believe in clean living and advocate vegetarianism. this hello message is not our religion. it's that they call it a right hand help because lot of people won't listen to religion, but they'll listen to health. jean peals late husband was a doctor. every one in her community make sure they drink a lot of water and exercise every day. they also believe in a day of rest. this community began and the early 20th century, when adventist pioneers opened the sanatorium, here it became the loma linda university medical center. the church is healthy, lifestyle seems to add years to its members, lives. the loma linda community is the core of america's blue zone, where people live much longer than the rest of the world. there's a city wide smoking, dan cardiologist,

gary fraser has investigated the 7th day adventists longevity and a long term study. we felt that it's pushed a head as compared to other californians, a man about 7 years and woman about 4 and a half, which is a big deal. i mean that's the kind of dane slit a whole population. mike, mike m a generational 2 generations. christine ho hits the pool to swim lamps every morning. a former nurse, she believes that exercise keeps her young and healthy. she likes to crawl a few length and then switch to back stroke with i like the bag straw because you can that you know, a brief vendor. and when, when i do vessel,

i see the sky. sometimes the sky clouds, you know, have different a, any more of formation. you know, i enjoy looking like that. her husband, james hope, please badminton regularly, always against a younger opponent, not all of the residents loma linda are elderly. it's a multi generational place. james ho used to coach the son of his badminton partner, who's 30 years younger than him. and make her active in michel. oh, golf home more portrait. he said those with relaxing. okay. the young people are the more saw that it makes me also wants to move with them at home. the walls are decorated with james hos many metals. now $82.00, he still takes part in competitions in the senior category and usually wins. but the couple also feel that a long and fulfilling life is about learning to save at the moment

both of us we had retired early enough, 55. take it easy. we do, i just and now money to leave on and, and seed the wool and enjoy. i keep the sabbath. i go to church and sing. ok, volunteer. right. they don't pay me, but i volunteer to help. that makes me happy because i can share my talents. we people oh, oh, marlon terry work appears to be another secret to a long and happy life. oh oh, as is the sabbath, the day of rest and worship? every one here follows the church as rules and adheres to its wholesome doctrine. most americans have a notably shorter life expectancy than many europeans and are more likely to suffer from high blood pressure and diabetes.

also cardiologist, gary freezer thinks loma linda could serve as a role model for the rest of the country. religion aside, this low magic elixir rules, pull it by, swallow something like this. um, it's rather we've taken many things that we know in the ve actually put them into practice as a whole group. jane peel takes an hour long walk each day, even in the blazing sun. she's convinced a few of her neighbors to join her. good job. well, i've changed my diet. i've lost some way. i walk more. yeah. yeah, she's that person. jane feels advice is simple. just do what nature, what god intended us to do, hidden tend to us do just follow pills and sit around and watch tv. get out. nature

get out and enjoy life. good grief. she doesn't understand why some people find that. so from us this week on global 3000, don't forget to send us your feedback, right to global 3000 d, w dot com. and we'd love to have you visit us on facebook to d w global ideas. the next time, take cat. ah ah, with
