the sects, undeniable these abdication of neither ship is criminal. the intergovernmental panel on climate change is latest report of as a shop wake up cold. around 3.6 of the almost 8000000000 people on earth live in regions severely threatened by climate change. temperatures continue to rise. 2021 was one of the hottest years since records began. global heating has dramatic consequences for people and wildlife. extreme weather is becoming more common. our oceans and sees a heating up becoming more polluted and ever more acidic. can we still save these ecosystems? we head beneath the waves. coral reefs are unlike anywhere else on earth, their home to mind blowing, biodiversity, the world's reefs are shown here with red dots. they cover less than one percent of

the ocean floor, but they actually support over a quarter of all marine life considering these staggering statistics. it's easy to forget that they're actually built from tiny animals, coral polyps, corals oh, a great deal of their magic and their beautiful color to a complex cooperation between organisms. algae live in the polyps, tissues and provide nutrients to the coral in exchange for protection. but this delicate teamwork is under threat from climate change. c o 2 emissions dissolve in the seas, making a waters more acidic and weakening coral skeletons. and that's not all. as global temperatures, sore, coral reefs suffer through ever more frequent and intense ocean heat. waves. extreme temperatures caused the algae to produce harmful chemicals, prompting the coral polyps to kick them out. this is horribly where

vibrant polyps turn white from heat stress, a process that can eventually prove fatal. and global warming is already driving vast, bleaching events to day. my son is for, as i told you, it's possible that his kids may never see a car reef it really scares me to think of a world without coral. reese, sherry konstantin of the nature conservancy has established a large scale conservation project in the eastern caribbean. the goal was to protect corals and other ecosystems while still enabling some tourism and fishing in specific areas. the fact that the community was so involved in the designation the design of these areas, that is why it was so successful. there are also plenty of ways to enhance conservation efforts, like these take playing underwater sounds to laura back fish for one slightly surprising example. and there is evidence that by shielding

reefs from local stresses, marine protected areas build resilience in the face of ocean acidic vacation and rising temperatures. so we have to have multiple strategies in addition to marine protected areas. this is lizzy mccloud whose global coral reefs lead at the nature conservancy. researchers like lizzie mccloud, are going one step further in the quest to help reefs resist climate change by investigating how to actually toughen coral reefs with. and so some of that the strategies people are using is, are taking corals that are we call express hardened, so they're better able to deal with ocean warming and actually transplanting and moving them from those areas to other areas with the hopes that they'll pass along that trait to their offspring and help the corals in that new area be better able to cope with warming. one way of doing this is to find naturally heat resistant. corals that have survived waters before into transplant them from one reef to

another. and these aren't the only cutting edge techniques other teams are also hoping to toughen up the individual corals themselves. in my research, we are mostly focusing on increasing the, the tolerance of corals to heat. this is ecological geneticist, madeline van up. and she's investigating a range of approaches to mit coral's more resistant to rising temperatures. for example, selectively breeding, to toughen up the pol of animals. or alternatively, tinkering with the algae that give coral their colors. the micro, i'll get a live inside the coral tissue. sweet. can they come out of the coral and most of these can be cultures in the lab. and in the lab, we can increase the rate by which the cell gay evolve. madelyn run up and used this approach to create heat resistant algae, which when put back into polyps,

created more heat resistant corals. so if we combine all of these approaches, is that it will we be able to save these unique eco systems from climate change? if we implemented every tool in our tool box today from marine protected areas, reducing pollution using some of these more active interventions, stress hardening or manipulating the genetics of quarrels. it will not be enough to save cor, reeves, if we do not reduce emissions that is absolutely central. the truth is that coral reefs are incredibly sensitive to warming waters in 2018. the intergovernmental panel on climate change warned that even if the world limits global warming to $1.00 degrees, coral reefs could decline by 90 percent. if temperatures increased by 2 degrees, that figure is 99 percent or higher. but worlds could heat up

by even more than this, given our emissions path. if we don't bite to stop climate change, the fight to save coral reefs is doomed, not in the distant future, but within just a few decades. coral reefs could be the 1st ecosystem entirely lost to the climate crisis. our environmental decisions around the world, whether that's reducing plastic use or limiting global warming, could make all the difference for the future of the world's reefs. are small and made of plastic sashes. these little packets might be handy, but they quickly land in the garbage bin, and they don't ross. in all web special, we chant the journey of such a sashay from the origins of the rule materials it's made from to its ends on the rubbish heap. we find out where the number of sessions is growing and why they're so lucrative for businesses. and so disastrous for our planet. find out more at d,

w dot com slash plastic lake. victoria is the biggest lake in africa around 30000000 people live near reads, and many of them depend on it for their livelihoods. but population growth has contributed to over fishing and pollution. threatening the health of the lake. but there are solutions for global ideas. our reporter eulley america, headed to kenya where local fishers are using climate friendly boats. as dusk falls, jared utter know hits out on to lake victoria. since he started using an electric motor, he and his team no longer have to breathe im exhaust fumes and it's not as noisy either. auto renew is one of the few fishermen here who started using an electric motor last year. it's much easier before he was constantly having to change gears

or so. you have to route careful, robert propeller dublin. so run it through tubes. it might order me get contact with her manila, you this 1st tree all the gear. so removing you to come cumbersome reviews, one you just do just automatically come up with electric. the fishermen use solar lamps to mark out the area where they plan to cast their large net with the light slowly attracts the fish to the surface. then in the early morning, they pull up the next day. the nights are long on the lake, only after 12 hours due, the fisherman returned to me again, a beach in the town of m b t r a t n a share. the proceeds of the cat with the other fisherman, after deducting expenses,

he only has the electric motor and batteries on loan from a company called a silvo liberty. every morning he returns the used batteries, and in the evening he receives a freshly charged set. a silver rents out the motors for the equivalent of around $38.00 euros a month. the batteries cost 7 years 50 per day. a lot of money for fishermen. here . there's a challenge rubric on the guitar lessons for piano, expecting them to the stress, to pay or to go potty special. so we have to look new for the address. ok, so back to come pick up the dutch started a sober, had to do a lot of math to develop this business model. they saw the batteries and motors from germany. here in kenya, they have technicians who take care of the repairs and maintenance. they also offer a 24 hour service. if there are problems on the water,

the fishermen have to call their rescue number that we can resolve on court. but sometimes when their technical issues are not in a position to be solved during that time, they have to, we have to send out his keyboard to go for them back or maybe change something, a component of vengeance for that matter. the batteries are equipped with gps track is so that the boats can be precisely located in case of emergency a. so we'll 1st started testing it system in 2017. but everything was delayed by pandemic. in the meantime, more than 15 fishermen have signed a contract with the company in and look at it. every new customer receives a free training session. so it depends on the coffee table in just a few days. they learned the most important things. that reversible theory were then practice on the water to get used to the email that was close. joshua america has been involved since the stars and understands what the fisherman need. the

company we lou lou lou will need to, to do some more difficult on i'm only really sad that the inital mobility cover alaska, our fishermen, most of them try to go find the stars a sofa is working to improve the situation that it's made contact with companies and kenya and uganda that refurbish used batteries. these could be rented out to the fisherman at a cheaper rate. in the 2nd life batteries will make them more duleigh, so that also we much, we mimic the current operations of our customers. but if, if a customer want to go far, we give them more bodies, then we charge this rich, i'd feed, but, but to the lake you want to go far. we give you full batteries, you want to go short distance. we give you one or 2 batteries and you pay for what you are used. a sobel as the 1st company in kenya to invest an e, mobility on water. and one of the few in general on the countries

a market. electric mobility is still in its infancy here. there are some electric cars and buses and even some e bikes. warren, on don gay rides, one of them. he's a member of a e. m. d, a, an association that provides a platform for the nearly 20 companies investing in e mobility in kenya. the aim is to organize the lobby, urging politicians to promote electric vehicles. people are excited about immobility, endo petite, that he brings. it has tremendous environment of benefits. but unless we have the right incentives to allow for the final price and the value to the customer to be affordable, then immobility might just as well be another illusion that will struggle. that gets towards around $25000.00. both are out on lake victoria every

day, and many of them belong to kenyan fishermen who used combustion engines, which pollute the lake and home the fish population. often the fishermen only get small silva cypress from the lake. and there catch quote has have also declined in recent years. derek aquinos, wife and mother take care of the cat every morning, 1st drying it and then selling it as quickly as possible. the fish are the main source of income for the family of 12. they also use the money to pay the school fees for their, for children. and they've even managed to build a 2nd boat. jared atlanta wants to equip this one with an electric motor too. he has a plan for his family guy, my father, our one source of shaman. then now is mere fishing. then what of my jewelry saw out of this one? i'm praying, god willing that my should i know to be fishing us. so these to do their best for

another system. there's why. now, i'm so i put in a 2 cushion, provide a would additional from bare b. if they're employed, they can change my, our life. jerrod aquino has already persuaded some other fishermen to switch to electric motors. but he and a silvo are still among the pioneers of e mobility and it will take many more like them to see a benefit to like victoria and it's fish good thousands of years. the indigenous peoples of north america inhabited a vast region from coast to coast to day native americans make up just 2 percent of the us population, a small number of on reservations, most of them in poverty. now some native groups a working together to provide some of that old traditions. and that means bringing back the bison.

while rounding up these bison, robbie magnen needs to move fast. he's responsible for more than 50 bulls cows, yearlings and calves. trick kid. gold goodness, and we'll try to think you can kind of think of a little background before their journey to their new home. these animals have to pass one last health test. i work these guys every day. i know how graff with them here at the ford pick, reservation in montana. ranchers are preparing the bison for distribution to indigenous tribes. for years magazine this been working hard to ensure they can from the prairie. again,

they're vitally important to many native american. ah, he'll, he'll fight everything in here. some more, get murphy. they, they had stressed out very faster. you want to work on quick as possible. so you know how a heart attack, how do you try unit test him, get him out. lemme go. the reservation has invested a lot of money in this facility to comply with the re relations this only after up to 3 years of quarantine and many blood tests are the bison permitted to be transported to other states. though the still wild animals are reluctant to let that happen. they also a poverty or boy or to a high viewed as it is. yeah,

very very. they're telling you what you wonder they what they're testing the by since bud for brucellosis bacteria. a disease originally brought over by cattle from europe, which infected native bison. should a conventional cattle? don't have the bacteria, but farmers feared their cows might come into contact with bison and contract it. so there are strict rules and lots of testing. this veterinarian has a routine vein that runs down or failed it. okay. didn't. and anything happened when you had one now? yeah, no, nothing would. yeah, no, no. yeah. each animal is meticulously documented. biologist, megan davenport of the inter tribal buffalo council says there is no evidence that by st pose a threat to cows, they've gone through 15 or 16 tests at this point in their life. there is never

been a positive reason. after the 1st phase of quarantine, which is literally just like the 1st female, this program in there on your 3 or so now, robbie magnon knows what it's like to wait for the lab results. the director of fort pecked fish and wildlife department shows us the reserves pride and joy to herds of bison. the commercial herd brings in money through hunting licences. the other is a cultural herd. only tribal men is are permitted to hunt each herd as 10 square kilometers of land, bordered by a fence that can withstand the basins brute force. though macklin calls these creatures buffalo, claiming only politicians or scientists say bison or the crater put us on there. we were dumb, well, you know, 100 survive as humans. so he had to bump will come up and take care of us. and they

also survive many native american, c, bison as 4 legged family members who are vital to their identity. but from the cattle industries point of view, they are bad for business or a fear that before all take their grazing honor, which is not really true. because buffer all what they call all year out for food. they deal in one day with care to we're not really in a competition with them. and there's that is big enough for both of us to live, but to people won't see it. it's a big deal. and it's minus $25.00 degrees celsius. these base and come from yellowstone national park, when huge herds were slaughtered in the 19th century, a few 100 animals found refuge there. that's why genetically pure bison still exist today. oh,

no way. yeah. oh gloria, accept of all 4 of the whole temperatures and hot with just a lot better than life. the results have come back negative. no bison have blue. so those bacteria, the 1st truck is going to washington state. the 2nd to oklahoma. there's a whole family and each one with bulls, cows, and calves. it's stressful for all concerned. 2 native american tribes hoped to establish their own herds with these bison. the cattle truck is the final, her muffler really? it is wild like just a year now. car and every other of these large north american animals. do they have to be moved on tracks this way because there's no tolerance for unity walking. they're on their own 2 feet, 4 feet. robbie magnon dreams,

that one day bison will roam free across the prairie again. he knows it's just a dream, but he's taking big risks to make it happen. in the end they're all safe and sound man and animal ha ha. turco bridge. we're done. oh yeah. dr. on journey joker whole that should be good in a traditional blessing for a good 20 hours of non stop driving. every few months they transport more by 2nd. one more step in it's slow return.

global. i am a global t who this week are global teen comes from ivory coast with my name's i should get to the re, i'm 15. i come from molly, but i live in ivory coast ah . with the freight i have a little brother and sister. i like to play with my little brother and tease him because i tell him everything is super easy. you're happy with a general good. i like school especially my new and good is your is on. i feel good

there because the teachers listened to me. these are gone on thursday, i have online classes which helped me improve my computers because i didn't have that before going pricey. ah, some more value in my free time. i like to watch youtube videos of funny ones or dance videos to dance and exercise to in with secure if i food makes me sad in visual i seeing all the st. kitts stuffing some have no family members do but live on the streets since they have no home or money

by the amazing or by the way. ah oh thank you so much gotten better is that there's more freedom to express yourself . why fi, likable me on my grandmother wasn't allowed to express herself or where what she wanted to buy this vehicle. but i can dress how i want medical and say what i think should be done in when i get your co schedule. ah, that's all from us at global 3000 this week. thanks for joining us. drop us a line at global 3000 at d w dot com and check us out on facebook to dw global ideas. see you next
