classified small handful of animals as edible and all the rest of the classify as disgusting. the w series about our complex relationship with animals. the debate watch now on youtube dw documentary. the boy goes in pakistan is feeding the joy of books and the is the hope for los angeles, many homeless, the ends could ocean's souls on energy needs. the

almost 40 percent of people in pakistan lives below the poverty line. aaliyah knows any too well. how tough matches were on the beach of karachi unpack. it stands a reading and see sure it's a long weekend, the fun on the waterfront for pakistan's middle class, the country is facing a crucial test. we can sense that here. nobody believes that anything will change quickly and fundamentally after the election, if you're a guy, thing with a heart goes with the problems with these things. so it's 3 of you are going right . i didn't show up on the evening before, after landing, and the 25000000 inhabit at metropolis. we realize what the norm is, challenges any future government here in pakistan would face. it's only rain for an

hour before arrival. and large parts of the capital are practically underwater. even the next morning, the water has still not drained away everywhere. and then narrow streets of karachi is historically already district. we want to know what people expect from a new government. as a very few foreigners come to this district, notorious for drugs and gang crime, we are immediately surrounded. everyone wants to tell us something. what we need here is like tricity water, gasoline. i mean, that's all we need here, but can we help our selves with that's what we need. somebody to hold up and move a standing thought wants to show us some things that they were really proud of. here. we follow him to a place that disapproves all of our prejudices. greens and young women spare spell bound and what's happening in front of them. and they watched everything closely.

fully concentrated and engaged people started here 7 years ago. here in the boxing arena in li, are you doing this? is the new generation is doing really well. this is pakistan's future. we all hope to step into the ring for pakistan in the future. what's unique, it's mostly girls who bandage their hands getting ready to fight. good preparation is important, since they're no longer friends. once they enter the ring, that we need only assume are all in the boxing ring. she's tearing on her friend and is fully engaged. she herself is not fighting today, not her age group. now i, the floss was, you know, are this ring is if you're going to ring and you're going to, you know,

your readings, like i wasn't going the thing and i wasn't reading the after the 3rd round, it's clear that her friend has one, the boxing sleek and the stands in the coach, all tier. the champion gives a friendly pan on the band. only is the star of the scene. we need her the next day at her boxing club at 18, she has won nearly every fund in her way. plants so far in karachi and all over the country. she trains 5 days a week and gets it her all isn't hard game and i'm not doing and i'm not, i can't do this on icons doing for boxing. so it's not good. but if you're saying that icon to anything, so you are do anything. yeah. preparing for this foreign match with her best friend, warming up before getting down to business. so i am an idiot ready to him to form

a fight. and i'm so excited because i'm going to fight in that way. you know, what like i, my feelings was angry. i read it for my opponents, for some neither of the 2 friends gives in the dance around each other, get each other, give their own 2 minutes to find a box in between girls and young women has long been found upon and conservative. most of them pakistan but on here and her friends no longer wants to fulfill the traditional semen enrolled in charge of boxing. so people are also saying that you are a god. you are not doing this of, of activities because it's not your work. uh, as far as where i go, but are saying that you are a guys who are also involved and making the fords. and uh, like, uh, you know, after a matter do, you are also how is that i so you're not doing for other things, but this is not a good thing. i think so. but things are changing. even for the men watching here,

there are more important things than tradition is going was he doing over the we should do much more for the girls and encouraged them. we have a lot of drug problems here. we have to get the use out of it. and motivate them to do sports for the sports people to play. cat aaliyah shows us our neighborhood. she confidently states that we don't need to be afraid if she is there. everyone knows her, but it is dangerous. here. you are them here. so gang wireless and like a get him for anybody. but that's why people are also saying that this is done through. yeah, and i'm not coming here and do, but i also gave him for my uh, my 1st sense and my family works. and so that's what people are also saying that i have not come here. but poverty is the biggest problem. packet stands, economy is on the verge of collapse. aaliyah takes us to her home. she says that her family doesn't have enough to eat every day. we meet her father, we climb

a ladder up to the roof as there was no room for all of us in the small apartment. he says he was happy to offer his daughter a different life and that the blows to her face would often lead to swelling that she was getting rid of. sometimes i have work sometimes i don't remember now was one of the best for my children. there was no one to all eager to learn english properly. i sent her to a language school for a few months, but now i don't have the money anymore. i had to give it on 6 year olds a month for her education is too much. she's now taking her feet into her own hands and wants to become a professional boxer. she accept all the hurdles. and in john la, she will make it every 3 minutes. she has only 3, the around 1800000 people worldwide lack adequate housing. the issue affects even

wealthy countries, the number of homeless people in the us recently hit 650000, the los angeles rock bottom here on skid row, the cities worse neighborhood, and one of america's most dangerous. even so we can film here because we are joined by the general and are able to get some rare insights. he's been living on the streets here for almost 20 years. he's 61 now. and skid row is this life is young son lives far away with his mother, the 6th. they see each other every 2 months. the general lives here and

this tact. this is only hands, believe it or not is my thing to. so it was like a mcculler mast about master boot. that was like the gyptian of those to build the small peer major. they can fit in and they would thing thing. but believe it or not, i get a lot done here as a way for me to get away from the world. you know, it's there means that he will cool world idea general dunc on with his nickname and present. first came drug addiction. then a life of crime, a bank robbery logging, residents of people to be served 11 years, a time spent reading about prisoner's rights. he wrote prison complaints and became inactive at one of the parks that was of the account. so remember one, now he works for an aide, organization and or, and so it was $1500.00 a month or a 1000 for his wife and child $500.00 for himself residence. he believes that politicians want to keep get road this way on the road to get rid of the homeless.

here are straight to jail because the city took everything up because they want us to poverty and homelessness has always been criminalized in the city. like a homeless people has always been looking at a looked at 3rd class citizens, the generative society. right. and with that said, investments have never been put in to homelessness and stuff. right. that they've invested or go to investments has been put in, but not in housing before police. and so the majority of the money, the reason why come you see all is because the majority of the money goes to police and the homeless as opposed to housing. the home, it's the entire neighborhood. it's in the us or segregated and consistently neglected, especially black neighbors. it was called red lining, and its consequences are still felt here. she are already and hopelessness. the feet wide helps the homeless with his organization l

. a can general dog on also works for it. pete life wants to dispel, submit about homelessness. if you create a whole policy routed in people or houses because they want to be because of their substance abuse because of mental illness. and the government has no right, right. like the government is not responsible. well, when you start talking about housing, affordability, housing availability barely start talking about structure. permanent housing is the key. this city of los angeles has also recognized this, but there's not enough affordable housing. a one bedroom apartment, a lake cost an average of $2000.00. maria esparza was lucky. after 2 years and a homeless shelter, she found her way into a city program. and now has her own apartment, has not been yet. it's

a day of new beginning for me. i mean, i love my place, it's comfortable. i love my big, huge package. you know, and like i said, just to be able to sit here and just, you know, do you art work? right. listen to music, watch tv, and just be by yourself is very nice. you know, uh, i missed that. and in the municipal programs, there are social workers in every home to help residents get back on their feet. also for the long term is hanging over, but there's a shortage of hundreds of thousands of apartments. so because it has a lot of meaning to so the city is trying to build quickly, re purposing municipal buildings and hotels. and i'm trying to stop people from losing their homes and the 1st place what we want to do is stop the end flow into homelessness right here. now, lake county, for approximately like we're able to bring about 200 people inside every day in the

housing, and about 220 people become homeless on that day. so we're, we have to stop the info into homelessness. if we're able to stop that inflow, then we'll be able to solve how much that is, even with the $700000000.00 that california has made available. they struggle to cope with the problem. but emily can active. this seemed like at the end of the tunnel now it's just not the black and brown poor people. now you have white folks in asia and folks and others who are struggling in this. a kind of, i am, have seen that with so many other new faces joining the ranks of the poor that we will be able to build the power necessary to actually have policy that values overprint the american dream may be unattainable. but there's always a little hope general dog on is trying to save some money so he can move from

a 10 to an r v the the. so the my wish a dream would be where everybody have a place. you know, like the rats and roaches. we all go somewhere to go, crawled into the cubby hole. it's evening and last angeles, and as many leave the glittering office buildings for their beautiful homes. right next door on skid row. some people prepare for another rough night. the grenada, with its tropical heat and lust greenery, is a caribbean dream. on the east of the island, norbert, julian's tranquil farm,

coconut sentiment, bananas, papayas, and frankly, the trees full of not meg. to see not legs of different stages. no 4th of all that through the very 10 to feet. yeah. very 10 to young. right. from that fits it goes, it could be that states. right. and then after this, these, it come to that stage. how about example here? like we actually pop separating the, the, the, the part from the not make side. so if i open it all righty. eventually if it's open. right. and then it will fall apart. i know this is an adult, much will not make at 1st glance, his plantation looks like a garden of eden, but it's threatened by climate change, and the warmer is the water gets the more destructive are the hurricanes. a good

doesn't hurricanes occur in the caribbean every year of these, an average of 2.7 become devastating or catastrophic category 3 to find storms. norbert remembers one particular hurricane with horror in just a few hours. he lost everything. everything was set up, right? everything was ready to all the trees on the ground and only a few tree will find them still. so everything was flap, don't update for us, not us. so you know, bankruptcy. we have both a month to pay us on the phone and the ring died. so try, which is it, is it is really, yeah, we those pi a vanilla or exotic flowers. almost everything trying same granados volcanic soil. the caribbean drain

still exist with a sense and unique flavors, sentiment, pepper cloves, and cannot make the the music clumps and specialty restaurants and the port of capital saint george's fill up and the evenings the tourism is in full swing until the next hurricane. most islanders rely only on hope that the next to retain sparrows will just close our eyes and get through it, send them, and then we'll provide caribbean spice for as long as possible. the small caribbean islands might completely vulnerable in the middle of the ocean. if a hurricane approaches the alarm bells ring in the media real logical operation

center and granada airport as with monster, hurricane events which reached the dangerous category 5 property, it made landfall on september 7th, 2004 that a half an hour. i think we had some speed off 11175. our strong ranada was set back decades. it's hard to imagine what will happen and the next to hurricane hits the island you could be working for 50 years to build up everything. i didn't want the one that's, that is all you. yeah. hardwood cause, i mean we saw that in the i 5, most of the victories went on a lot of people live off of that. we meet norbert julian's family at dinner.

they're all deeply religious. they say that god confronts people with small trials and big ones, such as past and future climate catastrophes. hurricane ivan pulled the ground out from under his feet. since then, his harvest has not been enough to live on norbert julian's main job, driving a bus. nutmeg is now just a hobby. the could oceans generate power. the technology to hong this ocean energy has existed for more than a century. it's known as ocean some energy conversion, whole tech. why has it yet to be embraced?

when you look at the surface of the ocean, the water here can be quite more because it's easy to apply the sun in tropical waters that can be around 26 degrees celsius. at a 1000 meters deep, the temperature reaches roughly 4 degrees celsius. and this difference in temperature is what the ocean thermal energy conversion utilizes. it's quite simple . you need a heat exchanger, the warm surface water heater of fluids that has a low boiling point. that fluid evaporates creating a theme. and that's theme runs a turbine, generating electricity. similar to our regular steam engine, then the spring gets cooled by the deep sea water back into liquid. and the cycle repeats. this technology was late in 1881 by french physicist a junk awesome dawson's on his student. josh quote then actually built the 1st spot on successful tech plan in 1930 later interest in tech p. when oil prices

exploded during the coil crisis and 1980 us president jimmy carter signed a loan to ensure the production of 10000 megawatts of electricity from opec in the next 2 decades. currently, there are 2 unsure of research plants, one on the island of coma in japan, with 100 kilowatts and the other one. and one are you with 100? 5 kilowatts. french developers were sent to launch a 16 megawatt plant to martinique in 2020. but the project has reportedly been shown due to technical difficulties. there were other research projects as well, but non lasted very long. so even though it's not a new idea, this technology is still very much in its infancy. most of the pilot plans were set up on shore to make a tech commercially viable. at that, a large scale, you need to go off short. this is him on kugler from mckinley ocean engineering, which has been developing low tech parts in hawaii since 1979. you know,

the 510 amount of sites would you need for your, your cold water and even for your return to your discharge pipeline as well. and the amount of trenching in shore line crossing for a commercial scale plants would just be infeasible. stem costs for him to as well going off shore makes it possible to install multiple tech platforms next to each other. similar to offshore wind parks, but currently costs are still more than double the price of other renewables. the tricky construction of the deep sea water pipes are turned off for major investors . but before we get into that, let's look at where this technology can be used. the major limiting factor is that we need a big temperature difference between the surface and the deep sea water. warm surface water is available all year round. in the tropical equitorial selling. so oh, tech would help bring more energy to tropical islands. many of them

still rely on peaceful generators. studies even suggest that if you disregard practical and financial hurdles couldn't power the entire world, hypothetically. today, estimates for a $100.00 megawatt o tech plants range from $780000000.00 to $1500000000.00. and there's another big unknown called water fight, and the pipes, the cold water pipe these days hard plastic pipes up to 3 meters in diameter or no problem. but for 100 megawatt plant using pipes almost 4 times that size, they haven't even been developed yet. it is complex because the pipe needs to be stable. i'm flexible at the same time to not break apart when it gets hit by waves or currents. development is tricky. and india no tech plant never went online. because the deep sea water pipe failed. and even if an old tech plant were to work,

it could be destroyed by a storm. that's what happened to one of the 1st pilot plants in 1930. this uncertainty has driven away companies with more than $40000000000.00 us dollars in revenue, lockheed martin was sent to build the biggest tech plant to date and china, but dropped the project due to its cost. but it's possible that costs could be caught. for example, in the heat exchangers to give you a bit of perspective, the heat exchangers on a commercial scale attack plan are about a 3rd of the entire project cost. so the, the reason that these are so expensive for commercial attack is the up to you. i came in deep sea water is very corrosive. we've developed what we call the tin foil heat exchanger. and as the name implies, we're using bin files. and the purpose of that is basically we're trying to reduce the amount of material and also the size. another big question mark is the actual effect on the environment because you're moving insane amounts of water. we're

talking about $4300000000.00 leaders of warm water and $2200000000.00 leaders of cold water per day for a small plant. there are a lot of question marks about our tech, the economics, the environmental side effects, the cold water pipe, and today's blogs. i just way too tiny to figure anything of that out. and in the last 10 years, not much. this happens without serious investment tax won't be taking off any time soon. would you like more insights and solutions from around the world? if you want to meet the people fighting climate change, visit us on facebook. if you want the story behind the headlines, follow us on instagram. and if you want green life tax checkouts optic, till the,
