power from the deep could all oceans satiate our future energy needs 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, the to dry to cultivate grain or vegetables. capital lie dead in the arid step plans to 1000000 people are at risk of starvation in kenya says germinate organization very tongue. i hamper 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, tubby american 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 youngel, that means decades in swahili rock goudrow, holla, bigler. hoa. 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 asked, what can we do differently to ensure the next 10 years will be better? the story ends in the year 2031. it just built people on the one that mirror for them to see that this is exactly what i'm doing. so what can i do? so yet again it's, it's, it's just a reflection of your life. it's all from the reflection. you can understand noise like a mirror if you have a, 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 as activists know, people here are placed with existential problems. only 3 months ago 40 year old shock her mother 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 grandma, i have to buy the calves milk because their mothers have no milk to suckle them. once that 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 chaco my 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 zeus. we're here because we're working on a program one environment. mostly what we're doing is looking into community resilience towards climate change. as we can see, that are the way they're part of the changing. we can see that the claim, it is not us, 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 here for now. one of them is 68 year old killough work. he told me, oh gosh, no jumbo lamita's every one planted trees. oh god, what will be good for the environment all night? she there all you're living conditions will be better. who did, we'll collect will people and that will keep people healthy as soon as you are yourself and according to ones there. 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 bes, 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 $1.00 of his 2 wives and the mother of his 3 sons, kabibi. kalauia had no such luck. name is the word that will like ruler, were real. and i didn't attend school, he because my parents weren't able to pay for my education. i live live or going on with those who are well i gave. so i decided to get married the nigger nigger more for neil. 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 foster world started the problem and is that people who can solve your own problem? she to ask 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 haughton, with ours, is all new to facilitate these discussions. facilitate to have them come together. that is what we are doing much, but the solution is coming draping from the people. after 2 months of consultations and conversations, the theater groups latest tour is drawing to a close. now. the safe, kenya. n 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 meg is not new. so my thing gave them. i have learned that when we manufacture charcoal, it has many a negative effects on our landed on my dad. i'm a co worker because i wanted to buy the legal monitor. 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 god, he hardly dongle 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 lost 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 villages 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 magnets pulling the water of our oceans towards it, creating a wave peak or high tide. 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 called tidal tobin. they sit on the sea floor and harness the energy in the moving water that comes in and goes out with the tides tell her just cannot sitting there and waiting to be used. the potential is huge. it's estimated the 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 died about a walk? exactly, and why isn't it every way it would total 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, and on the water as it flows in or out. and viola, you can make electricity with the same people. that window binds you moving water mix the turbine spin, this powers the gearbox on a generator, which turns mechanical energy into electricity. water incidentally is over $800.00 times damsel than 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 turbines. so far, so good. then back the titles from cod 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 waste 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 off was 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 bill or 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 around for decades. the oldest title reign generator lawrence was built in northern france in 1966. it cost 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 the runs is actually cheaper than solar and nuclear. there are 4 other titles range plants running in south korea, russia, canada, and china. can put toggle range on anywhere, but it wouldn't be economical to put it somewhere where there's minimal title rents . top rates on the funding and canada, the northwest australian shelf, the northwest european shelf, and to 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 apart from geography, the infrastructure to support titled range 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 bower. 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 use of the part of a lagoon 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 our consumption. but the other kind of total power generation could ship things up. the younger and sexier kind of the market titled stream power . it's showing more promise of the moment with its simpler devices that depend on underwater currency 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, it's 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 was like, corrosion is going to be big problems. you're going to choose your materials, really carefully, bio falling as a really big issue where, you know, you put something, the water is things are going to want to grow on it. and that's going to make it into a little mini regal habitat, the performance of the term of 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 global, not with financial support to death. the 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 id follow, but they could benefit when the costs of deployment begin to fall. charles, now as to bring down the price tag to, to make sure that it is something that is 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 in geneva, both meeting tied to and so it's been behind the cove in other ways to electricity from underwater died. 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 product from earlier decimated the populations of to 1st species. and like wind turbines that have been known to cause the lungs of baths flying past implored the pressure difference caused 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 speed. 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 prepared 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. tidal has other benefits to, 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, and course to long island nation 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 dania, 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, 80 2 am christine ho, 85. they're old and they're in great shape in loma linda, southern california, that's not unusual. oh, jean peel swears by a 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, if 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, whoa, 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 better, 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 rest of law melinda 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 o gall palm mall quoted. you said those of 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 the moment both of us, we had retired a early enough 50. if i take it easy, we do i just and now money to leave on and and she'd go whoa. and enjoy, i keep the sabbath i called the church and saying 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, okay. well, interior work appears to be another secret to a long and happy life. 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 lower magic elixir rules, pull it by, swallow something like this. um, it's raw, they've taken many things that we know and the virtually 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 picture. good job. well, i've changed my diet. i've lost some way. i walk more. yeah. yeah, she's a bad 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 hard. surely every one wants to lead a long, happy, and healthy life. that's all from us this week and global 3000. don't
