and conflicts one of the silence and fickle some casualties is often the environment. from the chemical contamination of soil and the collapse of water and food supplies. to the habitat damage caused by displacement. all has devastating consequences. no

sir any man made infrastructure but also natural ecosystems a destroyed. and animal lives are lost as well as human. it even makes the most vicious struggles three people fighting to protect the world we live in. and to cover what was lost. i'm tiny recede and bangladesh and the world's largest refugee camps where people are working to co exist with the elephant for which this region is home. and i believe it's on lebanon were group of scientists is rebuilding a c. bank that was displaced by the war in syria. in august twenty seventeen a brutal campaign of ethnic cleansing began in myanmar. the military in buddhist radicals claimed the lives of more than six thousand for him. in a single month. fearing death. thousands more fled the country for the force the bangladesh.

the scale of the accident was enormous. today they are still unable to return home. there are over one point two million working the refugees living inside of the sprawling cast upon the backs. this is now the biggest battlements of refugees in the world. many of them don't have access to clean water sanitation or even electricity. but after the ride the survivors face a new threat. while rampaging through can. i'm meeting on what about guns who witnessed the initial episode first hand it came from there. that left and came to pass from the jungle over that way went directly serra. called started feeding her hot with it but that's- this was no one on.

i'll instruct repeatedly throughout the camp killing thirteen people in the space of five months. can you tell me a little bit about what happened. last month another fighter jets we did. cool let it. what happened after that that. i sent the letter that i will put. you in with a lot. then i had even i used. yeah whole whole one another that they- sent a letter today. from what i did was a lot of. i got a lot about it. the i. tax sparked an

investigation into what was going on. i keep i mean from the international union for conservation of nature i believe the rapid expansion of the settlement had a profound impact on the natural environment. this is the edge of the cab or cave right yeah and this is where the force began yes. what's been going on with the cause behind all of these that is the only all camps they used to before us. the seems to be an elephant have habitat. the camp expanded at an astonishing rate. over one thousand five hundred hectares of forests were cleared. to accommodate the influx of hundreds of thousands of from hang of refugees. but nobody realized the devastating impact this would have. the growing camp suffered a vital lifeline for some up on the dishes last remaining wild elephants. blocking a herd of forty from their only path to essential grazing grounds in the east. just over dead that is that there is a species we

call the elephant corridor now the since the camp is completely blocking that corridor elephant cannot pass through this camp. is in search of his shelter in search of his food in central office my christian pop elephants was trying to calm inside the camp. elephant came so many times. and the thirteen innocent life was lost. and live in is not necessarily a violent mammal it's very intelligent understands it has these emotions. and it's just that these losses habitat. is desperate do this annual migration. it's in the dna elephant is a genetic memories and didn't know exactly where they have been going what they have been roaming generation after generation that did the same pot. the elephants of

bangladesh are critically endangered. they're just two hundred and sixty eight laps and they're increasingly under threat. fifteen thousand hectares of land are already deforested in the country every year. and this cap only adds to the problem. to help me understand what the elephants are up again i've hired a local guy. so the man in front of me is john i'm yeah his name means golden boy and he's our tracker for that day. i think we're going to have. it's not long before we find clues that we're on the right path. honda had them there hey how did out that is that when i say a bond with a mind going ahead his at kay. and you fell by the by defensive. with collagen that out without i will be sick. i thought that okay at the bangalore going because. we find evidence of hungry elephants everywhere. where to

take out. the sky like the elephant whispered. food. hey can i see this is the faith with again i guess if they won't they could very well following the actual footsteps of the elephants elephants have walked along this path every season for thousands of years i'm feeling really excited i wonder for actually going to encounter some elephants we're being told that just a few steps away that their their van. against the odds a moment i can't believe. a majestic i'll standing powered on the horizon. i've never seen an elephant like. it looks so peaceful in

its natural habitat. it's just really crazy to think that before the caps were put in place that this is what it was. a large forest with animals roaming about and now there is a human made crisis at play with sprawling refugee camps and is just a very sad situation. but a select band of refugees is working to solve the problem. with the support of the international union for conservation of nature they have formed a group dedicated to safely shepherding the elephants from the cap. they call themselves the task force. central sure their strategy are ninety four watch towers which they built around the camp perimeter. they are manned by a team of over five hundred brave refugees. ready to intervene and protect both the people and the elephant. i'm heading out for a birds eye view. okay so

what's going on there and they're simulating what actually happens when another from common. easy the dealership yeah in the end the mention possibles members so they are using the megaphone they know how to respond and even the foreman human shield and slowly moved to s. elephants. are that the leaf and understands the danger ahead. down on the ground it's clear how committed the task force are. i have any condition can include an. life here despite forty five incursions by elephants. it's an effective

temporary solution until a longer term plan is made for managing the animals migration. the task force has motivated the community with over five hundred people signing up to join. and has supporters throughout the camp. what are you doing over here what is this. by looking at the at the left get that i could get that how did you get that. eleven seventy one. the head and that may be i think that. all these different patterns and colors. seems like it's a lot of work to do why go through all this trouble to do it get out of the house my- mother had to be so much that. ms you the one on my bed but even hung with them using the- data they have whatever that the death of my yeah. meeting did you learn anything i mean anybody. do you feel that there's more danger living on the edge of the

forest versus people who live in the interior of the cap. and i'm like yeah. yeah he let get out that it was some good and money. i sort of. got on them as at the did it had a name. a at the man and i can somebody will love but on. dsl but i'm dances on the lady i've done a lot of the- in the- not only do people feel more secure they are also more sensitive to the elephants situation. maybe the animals is now even part. of the school's curriculum i think. you know i. the objective is not to build on this momentum. i keep is already taking steps to find a permanent solution to the problem. with an in depth scientific study of the elephants migratory habits. we are planning to put in a new column on the elephant this will give us a valuable data valuable signs to have a better management of the whole

situation. once the exact migration route is known the goal is to clear a path for the elephants so that they can migrate unhindered once again of course we want to open the coded alas alas possible and then i asked a few issues that we need to consider before doing this it will take about a hundred thousand people. would get people to move somewhere else that would be an immense logistical challenge. but as human refugees continue to resettle around the world. all the moves are needed to reduce the impact on local animal population. when i seen here gives me hope that animals do not always need to be victims of calm. and that a peaceful co existence is possible. the row over forty armed conflicts happening in the world today. each of them will leave a dangerous environmental legacy. we could see that's protection

environment is unknown something which we do their standards in place we enjoyed conflict isms if anything goes because. whatever damage he line connection accountability is never dress. we see very severe found damage to many countries and in many different ways damage to infrastructure such as sewage works awards of seventies. over extraction of resources. attacks on industrial sites causing vast amounts of pollution so you can have these impacts there's going to expire on the last two decades after the conflict and- when iraq in 200-016-2000 seventeen. islamic states at five. thirty oil wells some of these bands for nine months. covering hundreds of square kilometers in for lots of pollution. dealing with contamination caused by these files it's going to say is. so the last ten or fifteen years we've seen increasing interest from governments around such name vomiting relations complex he's got me favorites cuts me fast extol the conflicts of merriment. spam spend down is

in many ways and that has consequences. so unless we focus on the environment you're in contract and storing up lots of problems and. live in a turbulent world where conflicts and climate change are threatening our environment. scary part is that the cross for line for food are increasingly finding it hard to survive. and in some cases they're going extinct. crop diversity is essential for food security. and has declined by three quarters since the nineteen hundred. but there is an insurance policy. a global network of seed banks. these are back up repositories of seeds which safeguard their biodiversity. and can be turned to in times of crisis. when war broke out in syria in two thousand eleven one of these vital stores came under threat.

on the outskirts of aleppo the team of scientists charged with maintaining the seedbank were forced to abandon their work and flee the country. but they never gave up hope. when some of them resettle just over the border in lebanon's bekaa valley they began rebuilding their collection. i'm traveling to the i. card a seed bank to meet one of these scientists doctor ali shah hardy. hi alley good to see you good to see you what happened to the seed bank in aleppo syria. it became on possible access to the gene bank or three got the premises and over two thousand fifteen. because every band to access to the center by the armed groups controlling the area. they stole the vehicles of the stalled a lot of equipments. nothing left in the headquarters six of the buildings and the gene bye. the

war forced five million refugees out of syria. right now it's not safe for doctors to hide it to continue his work at home. how hard was it to leave that seed bank behind i spend more than. twenty seven years of my life working to the gym bag so it's a like is someone who left behind the babies or as long long history we dealt with them day by day we knew everything about the behavior all of those plants in the field in the plastic houses even in the gym bangs. time efforts made by everybody. both syria and lebanon lie in the fertile crescent which is where farming began. it makes this part of the world an ideal place to work on safeguarding future food supplies. this is the center of origins or we can pull the center of domestication because it's contains all the forms all of our crops like molly. we ate

lentil check please all these crops originated from this area. i want to get a closer look at the operation. dr marianna yes big leads a team of twenty scientists. including three who have relocated from syria. their task is to painstakingly rebuild the syrian seed collection. the c. vault here has a capacity the store one hundred and thirty thousand seed varieties for over one hundred years. the seeds are preserved by freezing them at temperatures of minus twenty degrees all right. there we go. there was gold. see you can see here samples of different crops are being conserved we're looking here at due to meet this is the heart the hard wheat that is used for pasta making so we have a big

collection of this and decide fair. process say fear that you're going to get your. all the crops are here you have here barley. a very important corpse when you talk about. dry areas and to talk with the three main crops which are we to talk what rice and you talk about corn. so these are three main staple food that most of the event please or using. a poor place this is a treasure these are important samples that we have to make sure they are surviving there are monitored they are. available to the international community. there are one thousand seven hundred and fifty strategically placed seed banks around the world. each gives a backup copy of their collection at the jewel in the crown of c. banks norway's follow barred global vault. stop the doomsday faults it is built into the side of an arctic mountain. so that the seats can be frozen without the need for power. over one

million c. varieties are stored here so in the syrian city bank was abandoned due to the war. dr yes sixteen were able to recall their backups. so the decision was made to reconstruct our collection with the three dead from small bar withdrawal part of it here to eleven on a new could build our collection here we could make it available again for researchers. all the seeds that come here are tested in the lab for viability. some are then cross bred to increase their resilience and improve productivity. you have to make sure of two things first that they are free of diseases second that they can actually germinate. they can produce. clowns they're alive and working and working see the each one of those samples should have at least eighty five c. out of one hundred that sprout and give. hello the that's right that's the first.

the seeds are thriving. the back in syria the war has decimated the country's ability to grow food. one of the goals here in lebanon is to create a healthy seed collection to help ensure the future of agriculture in syria when the conflict ends. up here from the roof i can see that there are fields their greenhouses there's even some cattle. and it's not just about saving the seas but also testing them trying to find out the best variations that can withstand climate change and secure our food supplies in the future. this region has been struggling with worsening drought for decades. dry soil in lebanon is similar to serious. by testing seeds in the harsh conditions here doctors hardy and his team can be confident that the crops will be resilient enough to survive the arid syrian farmland. what are these plants right here. this plant is a wise we this is opposed to

domesticated we they are very unique and very viable for our genetic resources because they have adopted already the to the harsh environments and has. very very useful genes to overcome climate change fx diseases drought frost. he. with climate conditions changing the biodiversity found here is vital not only for local but also global food security. already one of the wheat strains bread here has proven resistant to a disease known as yellow rust and has been sent to the us where crops were failing to fight it. but with global warming see banks themselves can be vulnerable. what's worrying is that melting permafrost is even threatening the svalbard doomsday fault.

research shows that the arctic town in which it's based is warming faster than any other. which makes the work being done in lebanon even more critical. twenty five syrians in the same number of locals tend the farm land here. so it looks like they're doing some really important work over here can i give them a hand yes of course they are doing hand weeding. seems that modern science hasn't quite figured out an alternative to getting down your hands and knees and just getting your hands dirty. so we're just looking for the weeds we don't want weeds interfere with his experiments. i wanna make sure that these crops grow right. and we have to also be careful not to. hurt the crops of the weeds kind of grow in between here. he really got of it have a good eye. ello mechanic media i will go on a sugar. with a the less than a minute then danny. and had assumed lesson haunting camilla is she miss the feeling of and

then got my son overhead by the- doctor ali has invited me for lunch. meals are of course the final product of the crops grown here. it's a chance for him to tell me more about the life in syria he was forced to leave behind. this is actually the. nice memory everybody had the role for reading because we had the- feel the effects of vital one case units had decided to go all together the breeders in the international stuff the scientists that technicians assistant daily labors even the tea lady contributed to that field day happy days it. was happy there is one of the most beautiful days. and you're sure you'll go back yes i am very confident that they will back because- i should go back. nothing like cold. it would be easy to write off the card a seed bank as just another casualty of the syrian conflict but the hard work and dedication of ali and

his team have ensured that their work transcends the conflicts and is able to continue to play a vital role. in protecting global food supplies. environmental for lots of war can linger for decades. but what is being done to heal the damage. the charity halo trust to plead nearly a quarter of a million mines from combo check. helping to make of the six thousand hectares of land faith farming. in cameroon almost fifty thousand trees have been replanted on degraded land around him in a while com which shelters refugees escaping violence in nigeria. i talked to fifty years of conflict unesco was able to protect colombia's to be contained rain forest a former guerrilla strongholds.

declaring this rich by a device to be a world heritage site. in the midst of rules the consequential damage the environment can easily be overlooked. if we don't act to protect on not sure what. be nothing left to fight for
