>> welcome to "global 3000!" in the fast lane -- cairo's rollerbladers are revolutionizing life on the road ♪ flying high with ai -- people with disabilities in india and, methane-free? is climate-friendly meat production really possible? ♪ egypt's capital cairo is africa's biggest city, boasting a population of around 20 million and counting.

the country's political, economic and cultural center is expanding ever further into the desert. while the world-famous pyramids were once located outside the city gates, they are now surrounded by concrete, asphalt, and a lot of traffic. ♪ rollerblading through cairo is a real balancing act. skaters navigate through time and space here in the heart of an egypt that's proud of its traditions, a brand new movement is underway. >> now you can find people who look like you. you know? most of the people here maybe never found someone like them. maybe they couldn't find people who were on the same level of

craziness! >> so folks who have a screw loose! there is no doubt that helps when it comes to rollerblading in egypt. here skaters meet to 'cruise' together. on this day, most egyptians are attending friday prayers, so the streets are unusually quiet. that makes it easier for kareem, who coordinates the get-togethers. >> at the moment it's gathering this huge mess, you know, of the people. but folks on the road and everything, we know it and it's easy for us. you see all of these people and you are responsible for them. so it's kind of hard, yeah. >> what's striking is how many young women take part, with or without adscarves. what's impe streets. we talk to dina who's been rollerblading since she was 13. and just hitched a ride on our

car. she says since covid-19 struck, skating has really taken off here. >> i think it may sound cliché, but it gives someone a sense of freedom. there has to be a bit of risk for someone to have fun. >> freedom fun and the , willingness to take risks -- that's an approach to life not often seen in a land under authoritarian rule, like egypt. while the skating scene here isn't really political, there's still something revolutionary about it. that has less to do with the many colorful videos posted on the internet than the message behind them. >> for sure we need fewer cars, not even with the electric cars for the environment. no cars anyway. because cairo especially -- and i think most of egypt -- but

cairo especially is filled with many, many cars. >> he's right about that. this metropolis of over 20 million people is frequently gridlocked. north africa's biggest city is choking on emissions and traffic is chronically congested. here at consulting firm "transport for cairo," they take a closer look at clogged traffic arteries and try to see what could be done to unclog them. >> taking away from the private cars or the other motorized vehicle modes to improve active travel will actually benefit the city. you have to make the case for it. >> it's not as if the authorities aren't trying. cairo's metro system is being expanded, that it's just not enough. marketing events like this are designed to get people riding bikes. a few new bike paths have even been built the trouble is:

no one uses them, because at some point they end -- forcing riders onto busy roads. >> there is still this getting adapted to the cycling infrastructure. even though we have had cycling in itself since forever. so, the mold exists, but the infrastructure and the safety parameters around it, it's still not very well embedded. >> back to kareem, the inline skater. he says bikes are ok, but rollerblades rule! for him skating is more than a hobby, it's a real means of transport. >> it's much better than the subway or the cars or anything. first of all, it is eco-friendly. you know? second of all, it's much faster. it's dangerous. it's totally dangerous with the cars and everything, but i've been doing this for years. ♪ >> and then he he sets off again -- back into the crazy traffic. ♪

>> you know, when i have an exam like in school or anything, i must be like 100 percent. skating in cairo, especially around the cars? i have to be like 6000%, 7000%. something like this. i have to be aware of every circumstance that happens around me, every car, every bump. anything that happens around me, i have to be aware. >> kareem bumps into his friend mohamed. they're both studying business at cairo university and have big career plans. and they hope to make inline skating a major part of them. >> it's my dream to have, like, a store here people come here and try the skates on. that will encourage the sport

more. it will make it easier for lots of people, instead of paying online and waiting for a month or more, you can come here and just buy it immediately. ♪ >> kareem even gets this reporter to give skating here a whirl. after a shaky start, we're rolling. he is on a roll! good enough for this promenade along the nile. but he will leave entering cairo's traffic chaos for another time. ♪ >> robots that build machines or dispense pills to old folks, a house which runs itself and autonomous vehicles welcome to the world of ai. artificial intelligence is computer software that is designed to undertake tasks on its own. ai continues to evolve in a rapidly growing, and largely unregulated market. last year, global ai revenues hit $450 billion, and are set to exceed $550 billion by 2024.

but ai doesn't work alone. it relies on past people for its development. and that includes those who painstakingly enter data into computers by hand. typically for low pay. for some, however, this work is far more than "just a job," as our next report from india shows. >> minu manilal is learning how to use computers and artificial intelligence, even though a few years ago, she couldn't even hold a pen in her hand. the 24-year-old from kerala in southern india has a physical disability. she has been extremely restricted in her ability to move since birth. >> i had a lot of problems with my balance. my head was always falling uncontrollably from side to side. i could never keep my balance, or sit up straight thanks to physical therapy, things have really improved. it's saved my life.

>> thanks to an innovative it project, she and more than 100 others with physical and mental disabilities have great prospects for work in the future. minu manilal has taught the fingers of her right hand to operate the computer keyboard because of the great progress she's made, she is now learning to capture data and to keyword it. this data forms the basis for programs that use artificial intelligence. soon, minu manilal will be among those who feed the info into the new technology. >> i never thought i could learn all these things. that i could given work in the it industry. i just wanted to do my best every day, and then all of a sudden, opportunities to work on computers here presented itself. that was the moment i realized what i was capable of.

>> the company was founded by robin tommy. he himself has been working in in the i.t. industry for many years. for one of his projects, he visited a school specifically for people with disabilities. there he realized what was missing: future prospects. >> we started giving them hope. now, hope alone will not work. we have to create an ecosystem for them to bring this change, sustain change and bring a circular economy behind it. that is why we are committed to do that. we cannot leave them with just technology, we are integrating that technology back to society bringing people together, and making sure everybody can contribute to the ecosystem. >> it all began here, in the therapy center. >> yes! >> this is where minu works on her motor skills with the help of computer technology. the focus is primarily on her stronger hand, the right >> very one. good! >> a big advantage of the playful training method is that the pain minu would have during the exercise has become

decidedly more bearable. >> i can only improve if i train all the time. in the beginning, i cried a lot. but now, the joy get from making progress outweighs any pain i might have. i hardly even notice it. >> robin tommy likes to follow the children's and young adults' progress. he has managed to convince lots of companies to become donors and corporation partners. he invests that income mostly in new technology. >> for any special education child, when they go through the ai based gaming therapy system, it gives a lot of insight to the therapist, what needs to be taken care of, whether it is the upper body. tomorrow, those milestones will be defined. >> the long-term goal is to establish the project at other locations in kerala. the "startup mission" could help make that possible. >> how are you doing? hey, hello!

center to specifically support smaller companies. these men are part of a group looking for innovative solutions for the medical sector in kerala. both see great potential in the concept of "inclusys." >> we measure their work in parameters. one was the accuracy of the data they researched, and two was the turnaround time that they took. and on both occasions, we felt like it was exceptional. it was way beyond our expectations, and we are now thinking of giving given more work. >> words like those are music to minu's ears. it makes the hours she spends at home in her room, learning computer commands and english vocabulary all worth it. >> different grammatical usages. l she says that at long last, it is all really paying off, and she feels like her work is

truly being valued. she says it is a great incentive to keep on going. >> i love looking things up on the internet i'm very curious. even if it's just little things. i want to find out and understand everything right away. technology has fortunately come a long way to make this possible. even with just my cell phone. >> the outlook wasn't always so rosy. even today, people with disabilities often have a hard time in india. her mother latha remembers times when technology didn't play a major role in society. when there was hardly any perspective in minu's life. at the time, they were resigned to their fate and didn't know what to do, but together, they got through it. >> we all try to support her. but it's mostly thanks to my mother that minu has gotten so far today. my mother told me not to cry all the time.

it was more important not to lose faith and to put my trust in her. >> that trust has paid off. now minu and her family are full of hope. >> i listen carefully, to understand things. at the beginning, i thought it was impossible. but with time, i got better and better at it. now i am being trained in it, something else i would've thought completely impossible not that long ago. now i know what i am really capable of. >> for minu, another exhausting day begins. she is on her way to the therapy and training center. another day of going beyond her pain threshold to overcome the many hurdles. >> perhaps the most important lesson she's learned: not to

set limits on herself. >> smoked, grilled, sizzled -- regardless of how it's prepared , global meat consumption has nearly doubled since the early 1960s. but that consumption is very unevenly distributed, studies show that the more affluent a society, the more meat people there tend to eat. which means that on average, per capita, consumption is much higher in industrialized nations than in developing ones. >> there is something about burgers. is it the sizzle? maybe the crackle, just looking at one almost feels savory. if only forgetting about their impact was as easy as taking a bite. but producing food emits nearly a third of all greenhouse gases. and of all food, these buddies are the worst offenders. beneath the massive problem. and to slow climate change, we have to fix it. is the only solution to all go vegan or is there another way? can we eat beef without ruining

the planet? beef production still affects you, because it's responsible for 4.3 billion metric tons of co2 every year. that's almost as much as the entire united states. and fixing this isn't as simple as everyone going vegan. >> there are these two realities, right, that we need to recognize. >> jacobo arango is a plant scientist and ipcc author from colombia. >> the first one is in developed countries where people may choose what they eat, there is at least another reality for developing countries. >> where people are struggling for nutrients, animal protein can make a big difference. and beefing up our beef production can help. but what''s the best way? very simply speaking, there are two ways of raising cattle. one is grass-fed farms, like this one in northern germany, run by heiko gluth. ♪ >>.

in the summer, the cows eat grass straight from the pastorate like you see here. and then in the winter when the , grass obviously isn't growing, the animals eat homegrown hay. >> this is a small operation - right now there are 58 animals here, 80 in the spring. >> these ones here in the front, these are calves from this year, the four. that one is two and a half years old. yes, and the next one to go. and that means a sale weight of around 300 kilos of meat. >> they roam around 160 hectares and have a warm barn for the winter. raising cattle looks similar to this in many places in the world. and then there are feedlots, that can have thousands, or tens of thousands, of animals. they live in a confined area and eat mostly grain instead of grass. as to which is better, grass-fed or feedlots, it's actually not that simple. let's compare sustainability using these categories. we'll start with what goes in. food for grass-fed cattle doesn't travel far.

these cows eat a combination of grass and clover, which contains more protein. during the summer, this is all harvested and turned into that for them to eat over the winter. so grass-fed beef avoids the emissions and chemical runoff from producing grain. it also wins on water. grass-fed cattle drink from lakes or groundwater. not so for feedlots -- the cows drink water. there is a downside to grass , though, cows have to eat more of it than grain. and what goes in, also comes out wherever cows are -- [laughs] -- all of these cars are basically constantly burping and farting, which generates a lot of methane. essentially, the bigger they are, the more methane they make. methane is invisible, so best detected by satellite. it's way more potent than co2. on a diet of grass, animals grow slower, so expel more methane than grain-fed cows. surprise win for the feedlots there!

what also comes out is manure and urine - lots of it. in addition to methane, it releases nitrous oxide, another potent greenhouse gas. in the summer, the manure decomposes in the field, and pollution levels are low. during winter, the manure is handled similarly to a feedlot. >> it all comes out here, and then it's shoveled over there, where it's eventually turned into liquid, and sprayed on fields. except on a feedlot, manure is stored in large pools, releasing more methane than solid storage. and the more of it there is, and the longer it is stored, the more it releases. ♪ one big downside to grass-fed farms is that they are way less efficient at producing meat. these cows will live to be 2 or 2.5, which is around a year longer than conventional operations. that means only 10 of them are slaughtered every year. cows grow faster on feedlots,

which makes them cheaper. meat used to be mostly eaten by the very rich, so more efficient farming has made it more widely available. but for grass-fed, you have to pay a premium. the cost of this meat is really high, at 22 euros per kilo. for comparison, this supermarket meat is 10. the difference in price does speak to a difference in quality though. >> i want the animal to grow slowly. when the meat is grown more slowly, that means you get finer muscle fibers. i am not producing meat for quantity here, i'm producing meat for the quality. >> quality is also tied to animal welfare, as stressed animals make for worse meat. and on feedlots, stressors are everywhere eating grain can cause ulcers in cattle, and they are often sick from the close quarters. transporting cattle is also stressful. ♪ even including the land to grow grain, feedlots use land

more efficiently than grazing systems. according to german organic laws, there can only be 1 full grown cow per hectare here. for scale, one hectare is roughly two american football fields. that's a lot of land. which we're running out of. globally, we are using two thirds of our land to graze livestock. as more people eat meat, more land is deforested to use for pasture. we're losing three million hectares per year this way. it's a huge problem, especially in the amazon rainforest. 40% of tropical forest loss occurs in brazil, one of the world's largest beef producers. production there is also extremely inefficient, and that's something that needs to change. >> one of the most important things we do is to increase the productivity of livestock. >> janet is an expert in concluding and evaluating greenhouse gas emissions. >> and there is a huge climate mitigation opportunity to do that, because the productivity levels across the globe can

vary by 100 fold. >> though if we continue to eat meat, feedlots also have their place but they need fixing. and they can be more sustainable, without making need super expensive. restrictions on the number of animals, and requirements for them to have time outside improves animal welfare. feed additives like algae can reduce methane emissions from cattle. manure can be treated to release less greenhouse gases, and not letting it sit for long periods of time can limit its impact. no matter what though, this needs to go hand in hand with reduced consumption in some places. >> if we actually limited beef consumption to about one and one half hamburgers a week, we could all still continue to enjoy beef. >> so we can eat beef without ruining the planet, sort of. people in places like the and the e.u. need to eat less of it, that is the most effective way for them to lower their carbon footprint. and whether through better grazing or feedlots, we can make beef production more

sustainable by improving efficiency. ♪ >> this week's global snack comes from costa rica. ♪ the costa rican capital, san josé, lies some 1170 meters above sea level. its city center is home to the restaurant "nuestra tierra." here they've been whping up traditional dishes for over 20 years, including a real classic, ♪ >> today i will show you how to prepare gallo pinto. >> head chef ronald muñoz starts by sautéing chopped onions with some garlic. then come the main ingredients, rice and beans. mix everything together and fry it.

adding green onion and spices gives the gallo pinto its signature flavor. >> you can prepare it in various ways. some people like it when it is still a bit moist. others prefer it to be fried a little more. now we need a little cup. we'll use to put everything together. a tortillita is a must. and some fried cheese. ♪ >> a fried egg is also part of this hearty breakfast. costa rica's national dish is served with a tortilla, fried cheese, fried plantain and sour cream. here they make up to 150 orders of gallo pinto each day, and not just for breakfast. the ticos, as costa ricans are known as, like to eat this rice-and-bean dish for lunch

and dinner too. all of the meals served at "nuestra tierra" are also available for take-out but they taste best hot off the grill. for werner and marieschen araya, gallo pinto is always a special treat. ♪ >> it's a country breakfast that has been adopted by city folks, because costa rican society is basically rural. we still cultivate these traditions -- that the milkman delivers the milk and that you go to the baker's to buy tortillas. those are all deeply-rooted costa rican traditions. >> gallo pinto is delicious, because of the different seasonings. it has a really special taste that's typical for -- and unique to -- costa rica. >> so if you are ever in costa rica, don't miss the chance to

try gallo pinto for yourself! ♪ >> and that is all from us at global 3000 this week. thanks so much for joining us! drop us a line at global3000@dw.com, or check out our facebook page. see you next time! ♪ [captioning performed by the national captioning institute, which is responsible for its caption content and accuracy, visit ncicap.org]
