this is a story of one of africa's giants. no his teeth aren't that sharp. and his neck isn't that long. list giant is rather modest and keeps a low profile that's not him either. people are often scared of this particular giant but he is nowhere near as dangerous as that one. is a friendly giant every day with the possible exception of weekends he saves human lives. his name is isaac a giant power grat. and i like his brothers and sisters he was born with

a passion for travel. isaac's birthplace was a special training center in tanzania. it's called. equipment that's what isaac is. mine sniffing rat. everywhere their social circumstances. with humanity. they actually traditionally.

mind. to work in former hotspots where learned mines are among the most deadly remnants of conflict they're often found years after. and serious injury isn't the only problem. imagine how it must feel to live with the knowledge that there's a landmine lurking somewhere near your home. when i was a close up children to help make the problem of landmines a thing of the past. but it will be a full nine months before he becomes a real pro for now he simply spends his time with his family. it's no coincidence that giant rats were chosen to sniff mines in the wild they're extraordinary sense of smell allows them to search for food buried deep underground

it worked with. the key used to train the a rats to associate the discovery of t.n.t. with food and that's not difficult because everyone knows how intelligent rats. the really hard part is making sure that the rat doesn't make any mistakes that could be fatal and not just for the rat. it's these old regular rats that's clear from the way they eat these giant rats have special pouches in their cheeks to still food just like hamsters so this particular animal is on the cusp between being a rat. perhaps that's why they're just a little bit cuter. i guess i should add to another really great benefit of our species of rats is that there are really curious which lab rats are curious as well but they are various

social in terms of they're really willing to work with people. sometimes will develop that relationship with you but i don't think they develop it quite as readily. meanwhile isaac has grown he's now four weeks old i'm training can begin like all children isaac's schooling starts with the kindergarten. although it is a camera he helps a little rats to feel comfortable around people. to see to defeat him to. be. the norm we teach the. truth.

interacting with a carer is a vital part of the learning process it's important for isaac socialism. mind sniffing rats mustn't run away from people. when he grows up our eyes are cool way around a kilo and his body will reach thirty to forty centimeters in length just about as long as his tail. because they're so big grilled. is our favorite local street food. started at school he spends his early weeks learning the basic rule that he means food. is used to reinforce the learned response as i can count as

an empty container there's no so. this one does contain t.n.t. and the click tells him that he can claim a treat. well in general the handler. really let her do her thing they don't get involved or train influenced her in any way but their adds to the rats as a different behavior just before they find. they have certain behavior some of them like to clean themselves elected groom themselves they're very clean. they don't like to get wet or maybe there's. some of them will walk around in circles some even stand up in the air. so they have no said she's found some think she just has. indicated where.

a rats remarkable sense of smell can detect the tiniest traces of t.n.t. . they can sense the. explosive even when it's fifteen to twenty centimeters on the ground their nose is not so secret weapon imagine if humans had similar abilities ok if you were in a pitch black room and somebody entered the house from. i would say i think one kilometer away and it's pitch black and you can't hear anything you might be able to detect something changed but that's also very hard for me to say because i really as a scientist i need evidence to support such a claim and i don't have. isaac and his sister at the gym they can give their paws a good workout sharpen their teeth. but enjoy

a sense of freedom. looks as though isaac's trying to set out on his first trip. nice troy. a brief chase. a few a breath so fresh. and he soon back in the fold. they know what they are doing they know what to be expect from. barry no doubt if do your work you can do very we want.

this reward. far from off. thanks very very very bored he learned most you have to do board and don't they don't understand so i remember very well the words. and that's what we are doing. for about a. week these students are only fed the food given the streaks during training. and. during the weekend. given a veritable feat. of peanuts and dried fish this. is great for their bones. you.

know feast. he. says here. in the wild. underground. quite independent within the. food with. females can choose their own. works a little like a parliament with both male and female members. it's

a big day for isaac. is about to move into high school. just like every graduate to be he gets his own personal transport. now. his field training. joint grafts are nocturnal they sleep by day but have active night lives. carers try to adjust to the rats biorhythms they settled at five thirty in the

morning a field training session can start at six. bits for moments like this that isaac has been trained is not alone by the sound of the engine. syria paradoxical the. comparison was a situation like israel in palestine is not a country where i meet

a lot of people without hope though everybody agrees. is a very serious situation people have been much more affected than in any other active conflict today. what politicians do you shop for you. they put themselves on the line to get accepted or rejected. so when you want to be president or injury. or somehow want to. have to go to beatrice that's what before three in the morning can't be good. i'm interested always in the waters in the house. there should be a. little bomb going off there's

a lot of muscle in the. islamic states claims it was behind the month just a terror attack by the with the militants fraud so kill the priest every time a terrorist attack happens all these people are out there screaming isis is so bad someone needs to do something against them and for me it was like yeah why don't we do something and. not. give the result the longer it goes up that up the case if. you challenge the check if pleasing chinese hafiz whom hope you sound good is going to. the u.k. consumers and. moved on.

michael grew should use. meat to train drink. again. and now you are getting the only. reason three come quick. so it's not divide man who is telling them. the black you have to do this in this in this manner. we have the older teenagers there is material enough for the old to be used to train the young.

isaac remained calm while using for his class to start. the trust between trainer and rat runs deep. he lets isaac out of the cage. without even bothering to follow. they have to concentrate them to be a viewer of their day they have to do to make an interpretation of for the writ is doing. when you are telling a. isaac is now demonstrating model behavior by now until. he sniffs

at the air. this is the result of several months of training. it looks as though isaac might offend some t.n.t. . he tries to rid his nose of all extraneous scent. he thinks he senses something but needs to reset his smelling operators to be sure . this is the spot. no. consent his signal.

it's like watching two old friends getting together. at first but for him or for me. i mean she was not running she was walking. she sniffed every room. she. liked records to steve to t.n.t. he. is asserted she wasn't there. t.n.t. . seems to have passed with flying colors.

now it's time to evaluate his loyalty. no one wants to chase a runaway red across a life minefield that would be deadly that's why it's important that the rats follow their handlers voluntarily without a leash. isaac is displaying textbook behavior as this training is over. now it's time for the real world to begin. traveling to see. in cambodia.

this is home to one of the ancient aka textural wonders of the world. and call it a fact. millions of tourists travel here to take their best self tourism is one of cambodia's main sources of revenue. but there are still landmines left over from the civil war and they are seriously hampering any further growth and tourism to say nothing of the danger to life. when it comes to square miles of minefields cambodia is second only to afghanistan

. the number of injuries caused by landmines is the highest in the world now though the situation is changing for the better in the popular tourist resorts mines can only be seen in museums but there are still many dangerous areas in the country. isaac is here to help with mine clearance. new instructor applies sunscreen to his skin. because giant rats and nocturnal creatures their skin isn't accustomed to high levels of u.v. if they were left unprotected they run the risk of developing skin cancer. ears and tails of the most delicate spots. we didn't see them doing this in africa because the training center was high in the mountains in the town of . at this time of year it's much cooler there than here in cambodia.

if we take a closer look at the probables it's raining but isaac still has some screen applied . the sun might come out once the team stops working. this is no drill. between dawn's protective vests and helmets. no one knows exactly health protection they get would offer. they're off to work. he's not a hundred like. you from the top and the next question is not bad but these are. international. if something exploded. in the

north being a scottish and down to something explored at least to a point that they don't want an office rather than having nothing. just as we make our way to the minefield it rains again. if we do rains and then. march. march march we think that there is no question i think taking a minis is going on is not easy for them. that's why when the rains a lot then we don't know what. it doesn't look as though we'll get to see ice a connection or range getting heavier. c

. c feet are. pretty good. very good. there. are. one more try. it's not clear if the rain will get in the way again. if the mind to take is out in the field after all. isaac is investigating the ground. nothing so far.

suddenly he starts to wash his face. this means he's identified a suspicious scent. the disposal expose approaches. he has been something. he seems to be really quite relaxed so perhaps it's not a mind off to rule. in

mind. i thought. it. was highlighted in yellow. the disposal team has. to work everyone gets a banana. and they all seem to enjoy it.

for this moment of triumph now it's time for a rest. real heroes glory true heroes need to rest to build up their strength for their future endeavors. another round of cambodia's mine clearance campaign has come to an end the field engineers have a chance to relax. take a leaf out of the book then night life is almost as exciting as the rats.

in. this story of a land mine and. that's all there is to it. credit is one of the basic instruments to drive an economy but it can also lead to tragedy i did it i took a line just i came to god and the debt style came and it was fire not. many lives have been broken really fixes to the banks going to.

the banks but i just didn't think of three. hundred creditors people see no future bad face for how you know you become ill you're going to job your relationship breaks down you become a casualty is a life long trouble or is there a way out of those actually trying to cover no would want to ditch bill for more a few more. sex guys or financial survival. when customers go by you're just a. good elf well reducing lower. that's undercutting but what's good for market is not good for the global economy. years ago i traveled across the united states exploring america's deadly love affair with a gun if a bad guy tried to get to one of my family members he would have better a lot better and i think they are encouraging when i buy my babies says my book was

published in the year two thousand more than hoffa a million americans have been killed in the us how to saute me as i did this is a middle school we go through drills and we put ourselves in real scenarios. it was interesting to see. him. i decided to return to the subject to track down each guy who i'd met and photographed those years of god i don't know that but we are not.

two more russian speaking children whose parents were killed fighting for isolate iraq were turned back to russia has been fucking a campaign to find the youngsters families by. the spanish government puts pressure on hundreds of dependents mayors in the rest of regional head of. the turkish president rounds on his nato allies off to raise concerns over an arms deal with russia.
