and everything. oh no, the answer. well im david here the answer to almost everything. our documentary series with clever, crazy grand ground breaking questions. can we go into the afterlife? oh we getting dumber. how can we feed every 1? 40 to the answer to almost everything. starts january 15th on d, w ah, ah, ah, welcome to global 3000 pollutant free fishing electric boats on lake victoria. the big come back

vice in a returning to the american prairie and catastrophic di, off coral reefs on the brink of extinction. the latest report on climate change has the un sounding the alarm. many ecosystems that at the point of no return now and checked, carbon pollution is forcing blogs was formidable on a frog march to destruction. now, the facts are undeniable. these abdication of leadership is criminal. the intergovernmental panel on climate change is latest report off as a sharp wake up called 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 wild life. extreme weather is becoming more common for

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 coral bleaching 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 far 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 rece. sherry constantine of the nature conservancy has established a large scale conservation project in the eastern caribbean. the goal was to protect corals and other ecosystems whilst 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 look 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, a certification 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 leaves 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 it stress 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 hot 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 tolerance of corals to heat. this is ecological geneticist, madeline van up. and she's investigating a range of approaches to make corals more resistant to rising temperatures. for

example, selectively breathing to toughen up the pall of animals. or alternatively, tinkering with the algae that give coral their colors. the micro, i'll get a lift inside the coral tissue, we 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 these sal gate 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 ecosystems 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 corals. it will not be enough to save coral reefs 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 inter governmental panel on climate change warned that even if the world limits global warming to $1.00 degrees, coral reefs could declined by 90 percent. if temperatures increased by 2 degrees, that figure is 99 percent or higher. but the world 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.

ah, they're 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 sachet from the origins of the raw materials it's made from to its ends on the rubbish heap. we find out why the number of sashes 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 it, 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 oliver or chinney was 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 move carefully to the propeller. the been so rainy through tubes . it might ought of me get contact with her manila you the 1st tree all the gear saw removing. you'd have gum cumbersome reviews, one just due to just automatic 3rd come up with the metric. the fishermen use soda lamps to mark out the area where they plan to cast their large net. with the

lights, slowly attracts the fish to the surface. then in the early morning, they pull up the neck. the nights are long on the lake, only after 12 hours do 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 or sabo. lab worker. every morning he returns the used batteries, and in the evening he receives a freshly charged set, a silver rains 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 with rico and the girl left out. we had a quick thing jeremy to the 1st page to go potty special. so we are looking for the

i buffer c microphone paper. 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 call. but sometimes when their technical issues are not in a position to be solved during that time, we have to, we have to send out as to what to go, pull them back, or maybe change something, a component of the engine for that matter. the batteries are equipped with gps, track his so that the boats can be precisely located in case of emergency a. so we'll 1st started testing at system in 2017. but everything was delayed by

pandemic. in the meantime, more than 15 fishermen have signed a contract with the company for in and look at it. every new customer receives a free training session. so it depends on the capital in just a few days. they learned the most important things that provides a mccleary. well then practice on the water to get used to the motor was close. joshua america has been involved since the start and understands what the fishermen need. the company we lou lou lou will need to to do some more difficult on, on only the list that are not the inital mortgagee cover. laker 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 country is 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 emer banassi and kenya. the aim is to organize the lobby, urging politicians to promote electric vehicles. people are excited about

immobility, endo petite, is 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 on out on lake victoria every day. and many of them belong to kenyan fisherman who used combustion engines, which pollute the lake and home the fish population up 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. derek atlanta wants to equip this one with an electric motor too. he has a plan for his family. get my father one source of fishermen. 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 beat fishing nursing. so the pseudo diverse for another system does, why now i'm support in the do cushion, provide a little bit of info from bare b. if they're employed, they can change my our life. jared 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 his 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 revive 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 is gold good. his hour, kind of 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 gravity i view of 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 nervous for you. they, they, that he had stressed out very faster. you want to work on a quick as possible. you know how a heart attack, how do you try unit test him, get him out, logo, the reservation has invested a lot of money in this facility to comply with the reg relations. 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 sell father's real boy does to a guy a few days. yeah, very, very, they're telling you what you wonder, you say what they're testing the by since bud for brucellosis bacteria, a disease originally brought over by candle from europe, which infected nato, 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 the sale that okay, did it and anything happened with hearing? all just had one. not yet. no. nothing would. yeah, no, yeah. each animal is meticulously documented. biologist,

megan davenport of the inter tribal buffalo council says there is no evidence that by saint pose a threat to cows. if antonio, 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 few in this program and there on your 3 year. so now robbie magnon knows what it's like to wait for the lab results. the director of fort peck's 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 members are permitted to hunt up each heard as 10 square kilometers of land, quartered 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 greater put us on there. we were dumb, will you know her survive as humans? so he had the buffer 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're that for business, they're re fear that buff 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 cal who were not really in a competition with them. and this is big enough for both of us to live, but people won't see it. it's a big day. 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, yeah. oh. yeah. oh gloria south of all 4 of the whole temperatures and hot with a lot better than life. the results have come back negative. no bison have brucellosis 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 to native american tribes hope to establish their own herds with these bison. the cattle truck is the final, her muffler

really is wild like just a year. and now car and every other of these large north american animals, they have to be moved on tracks this way because there's no tolerance, realty walking there and 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. took over. we're done. oh yeah, dr. on journey joke. all 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 its slow return.

global. i have a global team who this week our global team 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 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 awesome. you're happy with

a generally good. i like seal, especially my new and good. isn't his own. i feel good there because the teachers listened to me. these are gone on thursdays i have online classes which helped me improve my computers because i don't have that before going spicy. ah, some more thought 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 made others do but live on the streets since they have no home or money by the amazing or by the way. ah oh, thank you sir. what goes in better is that there's more freedom to express yourself . why feel my gum on me and my grandmother wasn't allowed to express herself or where what she wanted to buy this vehicle. but i can dress how i want miracle and say what i think should be done in when i get to schedule. ah, that's all from us at global 3000 this week. thanks for joining us. drop us

a line at global 3000 r d w dot com and check us out on facebook to d w global ideas. see you next time. take care. ah ah, with

who we've got to understand that globalization works, but he does not reach more than 30 percent of the world population. very simple in the mediterranean as become a kind of great sarcophagus. if anything he was proud of, it was to be a still a foreign ship, sorry, casmer fish. globalization. where do we stand in 15 minutes on the w and to the conflict?

so the context in ukraine is only one of the was vladimir putin is fighting. who didn't chief target in russia has been alex vonny, my guess is weaker exile in london is one of the valleys associate lab email, a shortcut, the group naming and shaming thousands as officials supporting the ukraine. but how far will that tend? putin is power conflict zone 90 minutes on d w. oh. hello guys. this is the 77 percent. the platform for africa's you beat issues and share ideas. you know, are these channels we are not afraid to talk to young people maybe have the solution. good future the
