originally the native land of fishermen as the population spite the demand for fish spikes to the high protein and new fact quality made them the go to food for the health conscious this puts immense pressure on the fisherman to fish during the breeding season or in dangerous waters or even over a particular species to meet the rising demand a unique calendar is helping consumers understand this phenomenon so that the fish and the fisherman are better protected. ok daybreak is a still a couple of hours away but business is in full swing at some docks the biggest and oldest wish landing site in the coastal mumbai. it is girls fisherman have landed their fresh catch hold selfish auctions are underway and fishmongers just through the crowd gathering full of bronze and a range over the sea from. long before mumbai became the burgeoning micropolis it is today its original inhabitants the colli fishing community lived very different. then we're going to we're going for there was a vision for the survivors what they were. wrong. whatever. and when the modernizers thought. prawns business started. sixty's and seventy's it was almost before the exports you know and that is why we started catching a lot for others you know. change. is a 7th generation fisherman who operates 3 fishing boats at the docks he has learned about the change in fish catch here only history lessons and witnessing some of it for himself since he began coming out here as chinese. my grandfather used to always tell me that how he was with the fish you know. was not so strong as in like just one soul or something like that and then slowly and slowly the day started. to continue days 90 days was 5 to 6 days in 20072010 fishing days were 10 to 12 days now the tolling is almost like 15 to 20 days. though in the gowns to 6.3 percent of global fish production fishing for a living could soon become economically and viable for another fisherman in this community. you know works with a group of marine biologists on bringing more of in this to the screen. there is a massive information gap between. the information gap in terms of what fish to eat in what season in order to minimize their impact on the seafood people are more than willing to do some subtle changes in their seafood you think that this is the only thing is this information is not available to them. in any fashion . you know your fish is the 1st of it's going seafood sustainability guide in india it is a calendar that details the species that can be eaten and which should be awarded in certain seasons. for each fish collected what they would need that would be publicly available and we listed richard of months. brigida fish nor is known to breed the months very recent. particular fish should be awarded. to that month where that fish believes all the fish which gets caught along with that fish. joe zamudio resident who found out about the gallon a year ago and now strictly follows one cooking for her to. dig to you even though i really like i've stopped eating them for me to 3 months in the year because that's the time that they breed interest in however this fish is something we can eat now has. also begun to follow the routine like the seafood restaurant in mumbai if we have different kinds of dishes on the menu then we would rather use a different fish for every preparation that is on the menu as opposed to those one fish on the end united mostly on the entire menu and that cans and that kind of makes it cool for us makes it slightly challenging to come up with dishes in the sense and the challenge is something that we enjoy. the restaurant staff see there has been a remarkable change in their consumer choices to. make the food. we were happy eating office to kind of not knowing what was. right and that was the idea of seafood for us and it was exotic but today we want to know where did this come from what is it that i'm eating was that line cord is a farm is that why i like when was this card is this fish fresh. new team behind the calendar hopes the behavioral change can someday result in a shift in seafood demand in supply. lega nodded mangos in windows and probably in some similarly we are going to stand you cannot very well among us so i think this has to come from. and when it comes from automatically fisherman i want the consumer to nor the fisherman as there nor the fish in the nor the fish they even know the fisherman i think it can work like that. but the x. x. comes to him with the preparation for the next one in the hope that the gap between the fishing community and finally closes for. a calendar like this which appeals to the better sense of the consumer must have given you an idea of how big the problem is fishing is a huge industry worldwide but remember these natural resources in our oceans are not endless let's take a closer look at the impact overfishing has on our planet. fishing is big business the un's food and agriculture organization estimates the value of trade in fish and fishery products were 29000 at 145000000000 euros the catch of fish and seafood has been growing for decades between 195-1990 the global catch sawed from under $20000000.00 tonnes a year to about 80 the rate of growth been slowed and the catch is now around 19000000 tonnes a year. small scale fishing is responsible for close to half the volume the united nations is keen to support sustainable fishing practices and goes back to a number of projects. one key factor is using nets with the right size mash if it's too tight baby fish or traps and often perish that contributes to the depletion of stocks industrial bottom trolling with dragnets is also very destructive of the sea floor and the. see regions. and of course all kinds of other species get trapped and often die this is called bycatch it shouldn't be caught in the 1st place. it's estimated that close to $30000000.00 tons of fish a year now end up as bycatch. it's a terrible waste and the death of juvenile creatures means of stocks of these other species are depleted as well. a huge problem is illegal fishing that is catching more fish than allowed under quota regimes often in marine protected areas. the volume is estimated to have been about 30000000 tons in 2019 that means a 3rd of the global catch was fished illegally. for stocks to regenerate illegal fishing has to be stopped as does fishing at spawning grounds during the spawning period marine protected areas need to be expanded and patrolled to enforce compliance with fishing restrictions these areas currently covered just 5 percent of the ocean's. marine and course still ecosystems are very sensitive and need to be allowed to replicate it and then natural is traditional oyster farmers in a small village in the west coast of india who used to harvest oysters in a disorganised manner have learned and adopted a sustainable practice of oyster farming. here. the women of the religious mother tower on india's west coast are busy stringing together oyster shells. they used to toil for long hours looking for wild oysters but often returned with a negligible catch. all the hard work did little to increase their. incomes. so what a lucky little army earlier to be used to go to the shore and collect naturally for an oyster is in the creek might be used to earn very little money and oysters could only be collected for about 8 days a month our hands and legs were always produced by our backs used to herd the sun was unrelenting to come of the budget a whole lot idol. rising temperatures and the increasingly late rainy season have seen the men's catches of fish constantly dwindle. so the women look for ways to maintain their family's livelihoods in 2013 they were approached by the united nations that a blackman program with a plan that would simplify their lives by enabling them to farm oysters in the creek near their homes. they were offered training and funding and asked to form a self-help group terra cotta. it out there but. eventually they set up the 1st sid the women's self-help group and after they were shown how to do it this started oyster farming the ropes are threaded with empty oyster shells oysters feed on plankton and waste and help keep the water clean oyster farming in course through what was its cheap and environmentally friendly. oyster loudly called spats attach themselves to the empty shelves within 12 to 14 months they grow into oysters big enough to sell and eat in better thought the crops are bountiful. the initial investment of about $75.00 euros to buy bamboos and groups has proved to be very worthwhile similar praja. have sprung up in our the religious along the coast knew much about it with a much weaker legit. my used to go to the fish market to sell my catch my friends would tell me customer reviews saw your photo in the newspaper and heard about the success of your project tell us more and i would say you can do it too you need to form a self-help group to get the project going mommy much him at the fish market i hope set up self-help groups i thought they should benefit from this just like the. product that it does our monitor was a well this is. the women of among the 1st oyster farmers in the state of maharashtra they only own a few rupees per oyster the money adds up at the end of the year they share the profits among themselves. pollution of the oceans and rivers is one of the biggest problems of the 21st century massive quantities of plastic waste ends up in our cities the ocean clean up project which is using the natural forces of the ocean to passively catch and concentrate plastic in the create with the fig garbage patch has garnered huge attention worldwide the latest project focuses on cleaning up dirty rivers. the interceptor and we increasingly is a large catamaran which collects plastic we just from rivers from the surface along the barrier over the conveyor belt and into dumpsters with this simple principle the organization wants to clean house in rivers that contribute to it people say of the oceans plastic before 2025. luckey more and more people are coming forward with their unique solutions to tackle water pollution we found yet another interesting approach arrived in amsterdam on how to clean. all kinds of daybreak swimming in this canal in amsterdam ends up in this catchment cage. a crew from the water company rotter net comes by regularly to empty it every week about a 1000 kilograms of stuff accumulates part of it plastic. this is how it works there is pumped into a tube lay diagonally across the bed of the canal and as scapes through holes in the tube the bubbles bring the waste to the surface the waste is then directed with the help of the current into the receptacle near the bank keeping it out of the north sea. boats and fish can pass through the bubble barrier the extra oxygen is also good for the water. the great bubble barrier was devised by an amsterdam startup of the same name yeah right on at this point the great little barrier is responsible for the maintenance of the whole it's still ation but that it is going to start doing research so they will start research on how much their stick is being collected it will also do research on how easy it is to be emptied the water company has crews and a fleet of boats that go around and pull trash out of the city's waterways last year that included more than 40000 kilograms of plastic the hope is that bubble barriers will make the job easier and more effective. that's what this test installation in operation since november should determine. the inventor spent years developing the bubble barrier. there were various challenges such as how to position the tube and resulting screen of bottles so as to direct trash to a collecting point and how to make best use of currents. the diagonal path is key. 4 people set up a company they now have a staff of 10. there's been a lot of resonance the technology is not particularly complex or expensive and it should prove to be very scalable phillip horn is one of the inventors of the system and he's continuing to develop it he's currently working on improving the catchment part of the process. with katherine so some we still want to improve a couple of things to be. maybe doing it more dramatically or calling for even smaller sizes of classic because we know that we can catch down to one millimeter in size of floating plastics micro plastics are a serious problem worldwide and jeopardize the food chain none the less offshore it is in the european union for example and yet obliged to clean the waterways of plastic despite the health risks we do see now with michael classics because that's a more direct threat to our health that something when we start to wake up if it's already already hurting the environment is usually not urgent enough. but there's still the budget around to to get plastic out of the water so that's certainly a challenge for us as as. plastic trash is a global plague that bubble barriers could help combat the team see a lot of potential for expansion. move towards europe within this years of 2020 but also move towards asia once we have a solidified partnership with parties in asia they hope to set up the 1st the bubble barrier in asia by 2023. what do you feel is becoming a bigger problem with every passing day fishermen in southeastern was shocked to see thousands of dead fish on their shores while they battle about the causes of this phenomenon with environmental activists and the provincial government it is their livelihood which is that. this lagoon is their life for money where martinez and ruben back fishing is not just a job it's a labor of love they ply their trade in the mama nor the smallest sea in the south of spain it's the largest salt water lagoon in europe but i mean if. it's a lot to me it's more than. some other. those waters feed us and provide our daily bread. but the lagoon is in crisis thousands of dead fish washed up on shore recently and it wasn't the 1st must die off. pollution has been a problem here for a long time. it comes from surrounding towns and from farming and the doll ends up in mamma nor this pollution promotes bacterial growth which is harmful to the seabed and that results on low levels of oxygen in the water and that will put in a little. the fishermen of mama no have hung up their nets for now they want to protect the remaining fish population and sales have dropped in any case due to fears of contamination the search for the cause of the mass die off is still under way. like the fisherman environmental activists believe that pollution is to blame pager garcia and when i dared say that over use of fertilizers in the region is causing contaminated water to wash into the lagoon for. intensive farming is contaminating the soil and groundwater with nitrates from fertilizers. a lot of that ground and surface water flows into the lagoon. the agricultural industry is mainly to blame for this pollution but they're doing nothing to fix it and i think that they're going to. have. studies also indicate that industrial farming in the region may be to blame broccoli lettuce and artichokes are grown here some fields have been irrigated illegally. but some farmers such as minnow martinez deny these claims he says that more and more farmers are switching to modern irrigation systems that allow them to reduce the use of fertilizers he says climate and weather conditions are to blame are going to go in the other mental old thing was our new have to remember that over the last few years we've seen a lot of extremely heavy rainfall and it's. september for example the rains caused a great deal of water to wash into the lagoon. there we're a moment on. the fishermen agree that climate change and flooding is making everything worse that's why farmers have to cut down on fertilizer use it's also a political issue the state needs to impose stricter rules they say which so far it's failed to do. on the local government has no guts for what they've done nothing to protect us here we've been telling them for years that conditions and mamma nor our terrible. local administrators say it's up to federal lawmakers in madrid to introduce tougher regulations. but after years of political instability the central government has left southwestern spain to deal with the issue on its own. and it's not just the reputation of the lagoon or of this region that's at stake here what's at stake is the invite. mental reputation of all of spain we have to learn from this that it's time we found a solution. that. by the time a solution arrives it could be too late for mine when my tina's and other local fisherman sam are already planning to sell their boat it might be years before fish stocks return to normal if ever. i don't know what to do. fishing is my life. i've been doing it for 13 or 14 years. my family have fished these waters for 4 or 5 generations that's all i know. some local fishermen have started heading out again even though there's little demand for fish from these waters they feel they have no choice. looking at the past if you laws are implemented and enforced better this is often lead to an improvement in environmental conditions more than 7000 miles away the city of mumbai too has struggled with the implementation of and among other things leading to a pull you out of course like a course like that has a rich biodiversity of marine creatures and environmental activist in the city is trying to raise awareness among its residents in order to preserve and protect this valuable ecosystem before it's too late. he has photographed more than 250 marine species in recent years. including the cube. and the blue button jellyfish. he didn't discover them somewhere in the wild but off the coast of mumbai. the foremost helps conserve the rich marine life the tribes along the city's schools line and also conducts sure during the tide. motive is lake popular a thing i don't know but ok so more people walk on the beach and if they see and if they find such or die with mining like i don't move very very definitely not. ok and they will start respecting or she thinks so but conservation will happen that will magically. the beaches of mumbai i want to some of the most polluted waters in the world but the 167 kilometers of coastline us to live treasure troves marine life weeping to be explored. with photographs but the pitot is drawing attention to waste disposal and environmental degradation. we are planning to document these things then definitely young scientist will. approach it explored be kind of. definitely come forward and do some more studies i don't this area. is work and preserve mumbai's beaches from further loss of biodiversity. simple actions like what fish we choose to eat and how we choose to dispose off a container has a life changing impact on marine animals and plants let's call it the responsibility of being a human being i would leave you with that thought we'd be back next week with yet another episode until then. how's it feel of the world. where i come from but all of that could just go just like this chinese foods doesn't matter where i am there's a boat which reminds me of home after decades of living in germany china's vote is one of the things i miss the most but better taking a step back i see things the need to differentiate knowledge. benefits of person as undergone a sense that exists to add the heart of the board haven't been implemented in china pats me for a lot of china to be appalled wondering if their fortunes. a lot of people have the right but the bet is this is the job up just out of them how i see it and that's why i left my job because i tired to do it except maybe an hour a day. by day medalling to work and i work at it that you. 2 actually meters just shows the 1st spread of shows. for the law. the smart way to get when you're going. global auto mobility every move on w. . every 2 seconds a person is forced to flee their homes nearly 71000000 people have been forcibly displaced the consequences of coming to some stress our documentary series displaced depicts traumatic humanitarian crises around the world you know. forgetting we don't need to i didn't go to university to kill people. or to have my boss come to me and tell me to kill someone and he got mad if i don't they'll kill me. people feel for their lives and their future so they seek refuge abroad but what will become of the others to stay behind and save up until my husband went to peru because of the crisis that the mother wanted that if he hadn't gone there we would have died of hunger the knowledge down the law because this week long. played . this is you know we knew his life then remembering the holocaust the world causes to pay tribute to the victims and survivors of the shuttle to. feel each. moral leaders are commemorating the 75th anniversary of the liberation of the auschwitz death camp the german prison.
