in a time of climate crisis, carmen santos research is more crucial than ever for months to come, she and her team will be coming back to the lagoon. each trip usually spends several days. the field work includes mapping the approximately 10 percent of wetland that's covered by c cross, which is one of the lagoons most valuable assets. they are very efficient carville scenes, which means that they can sequester and the store a huge amount of carbons in their biomass. and in the say, the one behind where they roll. and it's very important because when sequestering their seal to and the carbone that is store in their sediment, they are helping us to mitigate the climate change. scientists estimate that coastal ecosystems, like c grocery store 3 times more c o 2 than forests at no cost.

ready sherman santos and the team from y'all golf, sent off marine sciences. want to find out exactly how much of this blue carbon is stored? india formosa. they've taken about 80 sediment samples over the past 3 years. they slice up the samples and then analyze them. by burning them, the scientists can calculate the amount of carbon they store the team, hope that their research will convince policymakers, etc. grosses meet more protection because of the potential to absorb you tube. their insides could also help on the local level in coastal development planning. and on the global stage, the findings could aid efforts to reach climate neutrality goals. see grass meadows world wide on the threat from the incessant traffic of and damage caused by anchor

. in europe, the scene said 60, we have lost one 3rd of the seed was made that we had one of the major threats to cigarette. this is the amount of of bolt that we have. because 1st the travel very fast, which creates a big wave that hits the margins of channels and it roads for the course filled while the sediment would march under see good us grow with water pollution also threatens see growth species around the globe. stricter legislation has served to improve water quality into your formosa, which in turn has helped to see grass beds to recover. and that's, and if it is one of the lagoons most iconic inhabitants the see. their

numbers have dropped by more than 90 percent in recent years. primarily due to illegal fishing and the destruction of their habitat protective zones and artificial structures like these have been set up to help see horses need something to cling onto. a timer is the driving force behind the c horse project. he's studying the relationship between the animals and c. grosse as well. those areas are highly productive in terms of food and as a, as an appetite. and even if the sources don't use it directly, it was in the indirectly as it produced the food that later on. they will feed on small frames the small f people and all the food that is also provided by the ponds at the research station where george palmer works

well, it's feeding time for the see horses that the team breed here. palmer has been studying them since 2007. some of them will be released into the waters of re a formosa. it's a start o fully. it won't be a futile measure to support what's left of the current population of carbon santos and had teen planted c grass in the summer. now that trying to track it down to see if the plans survived. though cameras can capture them, divers can spot them with a naked eyes. hugh a vase when they ask and it's great to see that they, it works. so we'll see how that happens in the winter and health lead, sir. it goes well and we can see plaza growing and his breathing

across the globe. conservationists are focusing on replanting. c grasses like here near the spanish island of my ga, it's tedious work. the young plans are sensitive and the growth is slow. but recent studies point to a reversal of the decline of secrecy and europe assigned that protection and restoration efforts can make a difference according to a recent study by the aid organization, unit one wife. more than 1400000000 people live in areas with the high water insecurity. among them are 450000000 children. that is one reason why an initiative here any vendor is making those as available in schools. and that will private households to drinking water closer. this is the nike volley refugee

settlement in western uganda, 130000 people live here. 6 years ago dina been to fled the democratic republic of congo after rebels killed her husband. in ocoee valley, the lake is the source of water also for drinking for livestock as well. but the water is full of germs every year, 20000 children under the age of 5 die in uganda of diarrhea disease. one major reason is that they have no choice but to drink dirty water, heat kills germs. so dina been to boils, the water she fetches from the lake. she has 5 children. and i think that we will drinking water using charcoal, and if we don't have it, we use firewood. otherwise we will be drinking very dirty water that comes at a cost to the environment to make charcoal trees are cut down. forest also had to be clear to make space for the settlement but there's another way to provide safe,

clean drinking water south, be rudy and henry of vienna run to sir fisher, a social enterprise that makes automated low cost filters. this set up cost $1200.00. the money was donated by somebody in the united states. it supplies enough water for about 900 people out of 830000 in the settlement. but it's still a start. there was a that passes through our field that is the water from the lake. you can see this is the, the original water from the lake. and then after 8 buses through the filter. this is, there is out that we get out of the wounds you lost a brother to colorado. he drank contaminated water, access to clean water is a human right to sir fisher aims to deliver what the state fails to provide. it also developed a small water filter for home use to use is grenade to,

to purify the water. we have 2 buckets lit doped bucket contains the granite and then below bucket is there is above for this safe water. so they pour down the dope bucket. and then they all filtration happens in their grenade. only water and air gun is skip through the grenade and only safe water goes into the reserves. opposite of yanna shows people how to put together their own water filter. the granite needs to be cleaned every few months, then it can be reused. remember, we didn't have been to is intrigued if you feel to water this way. you no longer have to boil it or buy charcoal, which means lower emissions and costs. and there's another advantage, every time we stole anastasia and fuel deck, we train that women around our community to make sure that they have access to safe

drinking water in their homes. and they can also go and train either people or, or so mecca these, what a fuel does, then sell them an extra income for themselves. so to be room g and henry of piano installed the 1st large filtering system using granite in central uganda. in a school near the capital kampala, several 100 pupils now have access to clean water and fall sick. less often. utilities safe hasn't have anything so has helped me a lot cause i'm no longer suffering will take for you and even i stuff only pay for it and i was like, i don't even go to school too. so fisher has quantify the impact that use of its filters has on the environment in terms of trees protected and c, o 2 emissions. here we save the atmosphere of at least $240.00 tons of carbon dioxide for each filter at marine. godfrey's federal gland whenever

to sufficient installs a large filter system in a school. the teen plants. marina trees with pupils about a 1000 in all over the past 2 years. oh, at napa valley, dean and i've been to, had since acquired and started using a water filter. she put it together herself. my g in on the water from the filter is clean and usable reality. i'm very surprised that this is the same or to it was originally dirty after cows and people had contaminated it, you know? yeah, mile thanks to the, to sufficient filter. she and her family stand a better chance of staying healthy with less effort and at lower cost. however dirty, the water in the lake continues to be. bats eat from us to day. we hope you enjoyed this with sure. if you've got any thoughts or ideas about environmental protection that you'd like to share with us, please do get in touch while social media platforms will meet sun between you. it
