That he has some other tidbits will be looking out today. We look at why being a ranger in such a dangerous profession. We also see how a briefing that no which im already led to almost 1st stop them farming. And find out how blood waste is being put to use in the mud augusta. Being a ranger can be a dangerous job some 100. 00 wildlife guardians lose their lives each year in their line of duty many of them in east and Central Africa while accidents account for about 50 percent of those fatalities porches were responsible for the other hot we went so much sun force National Park here in uganda to meet julius or one now the warden in charge of Law Enforcement there he has been confronting these day in day out for more than 20 years. In the morning roll call julius of warner tells his men that poachers have set traps during the night to capture animals. They have to move fast to save the whales lives. After covering a few kilometers and foot with his men. But as the rangers comb the area looking for more he receives an emergency call. Colleagues in another part of the park have arrested someone suspected of having killed the buffalo. In his group got away. The rangers confiscate the meat of the animals here have protected status no hunting is allowed. That came from their communities of course. They claim we. Did this. In the process of cutting and cutting where they need. Coal. And they moved in swiftly adventures from these specific out force so. They moved in swiftly and they managed to one of. Their race parrots off. The storehouse poaching traps are piling up but. Its an uphill battle the more the rangers find and dismantle the more im made by the poachers there are people who have dedicated their lives into manufacturing these some of this. From. The acceleration cables of motorbikes which are everywhere in the shops so a person will walk into the shops as if hes going to my spares for their model break he does not on a motorbike and he asks for their traditional clutch cable which you can easily buy at a cheaper price and we turn it into a snare and bring it into the park some of the traps getting really evidence of the harm that the. Many animals also be at the painful science this elephant almost lost a truck to the poachers. Of one of this is that such cases are common and that is why hes always on the lookout for threats every day through out the park. Out there we know we have people who will always want to force themselves into a protected area to try and get these resources and. Where they come to get these resources and you do not have. Enough information enough intelligence about them then you are forced to move almost everywhere to try and get to know what is happening in part of their park so that you are sure that what you are managing is intact of oneness convinced the tourist pushers to create the illegal wildlife trade by offering them work. People like out that. Hes happy with his transition from poacher to gamekeeper of the lone buffalo almost killed him on foot patrol. He knows exactly the movements of the poachers. Because when i was poaching nothing i could get even if i went back with a meat refund that you can use it for pussy and i think i had it my to do in the not to study but at the time when i joined in now i would do what you did anybody. In money which im getting from from the back. Does possibly one is the warden in charge of Law Enforcement in march a sinful National Park he says the anti pushing efforts already paid off and tourism is good. Hes helped to arrest and prosecute over 700 poachers in the area julius obama has witnessed the population of elephants grow in the last 25 years from less than 400 of the animals to over 1600 today. Someone 4 to graf a mountain an inspiring campaign to fight plastic pollution around the world 322000000. 00 tonnes of plastic is produced each year and you can find plastic was literally anywhere much of it ends up in the rivers stephon hole which is trying to bring people together to change these and here is. This week. Hes getting closer to his goals Stephanie Halasz has been paddling for 4 weeks now from the western german city of copelands on the rhine to the capital by lynn in the northeast of the country. The joys of farmers even as on the greatest thing and this was a trip of 750 kilometers it is just one was to come up against your limits when you think youll never make it bring the new get a 2nd wind and then you do it because this is not march after cultivating. He started out doing the collecting on his own hed make an arrangement of the garbage from the rivers photograph it and put it on display its the photo designers way of making the invisible waste plain for all to see. Up on for 2 of them. I took a photograph that shows a kayaker from above paddling on garbage this is the average amount of garbage from one kilometer of river and kilometer from germany but not in asia and we have to work to reduce the odds are germany has a lot of kilometers of rivers drawn to reach the feet of whos going to meet up. In total around 7300 kilometers and stefan horse has only travelled a fraction of them so far. Alongside exhibitions he also organizes regular cleanup events 7 cities are taking part in this one like oberhausen on a tributary of the rhine. And what you have to look closely i pull out pieces of plastic all over the place to look just like the stones my boats already full up. Hes joined by new volunteers at every new stretch of motherhood siding was a hair around 60 cleena opposite on the water and the riverbank. Their life just because i think it makes total sense to not just collect waste from the rivers thought but also from the landscape around them. My eyes. I think its important to realize that this is not just happening in the caribbean or wherever be aware that it starts here with us im saying this. After just 2 hours theyve gathered around 2000 liters of garbage. Stephano wash needs as many fellow campaigners as he can get because thats plenty of work to do but hes happy to have come this much closer to his goal of clean water waste. While they were equal to the so much trouble. Amazing what people can achieve but now backed off because weather the best of contemporary attempts to combine innovation and age old knowledge to construct buildings that remain cool even when the sun is beating down outside indeed sandra in santa go a group of young engineers and architects have joined forces instead of congress they use oil to make compressed earth grace its an economical and sustainable building method now lets have a look see how far their work has gone. In senegal the summers are swelteringly hot without air conditioning life can get unbearable especially if you live in a concrete building. To do jem is a construction engineer he founded a company that produces bricks out of soil. The material makes it much easier to keep buildings cool. One of the benefits is that the thermal insulation stops cool air from escaping where a cement instantly lets heat in so you have to use air conditioning all the time you cant switch it off because as soon as you do the walls absorb the heat and let it in. The red soil in senegal is perfect for making compressed earth blocks. After 21. 00 days left to dry in the sun there ready to be deployed. Building with soil is a traditional technique but over the years the method has been refined the mixture used here contains 10 percent cement making the bricks more stable and water resistant building using earth bricks is far better for the environment than using pure concrete. Production of the brick involves a far lower rate of c o 2 emissions plus residents have less need for air conditioning. And how about you. If you are also doing your bit tell us about it visit our website or send us a tweet hash tag doing your bit. Share your story. There are reports that africa is a dumping ground for most of the global ways so what is being done in africa to change that our young nigerian if i you by name decide it he doesnt want any more and so he began to do something about it. Lagos nigeria has him to a number of illegal dump sites very waste for many local people the refuse is a vital source of income of the taking of poets t. V. s computers and other devices by hands they resell the components as Raw Materials its extremely hazardous work with water and ground severely polluted by heavy metals and toxic chemicals some Electronic Devices come from developed countries in the form of the nations unfortunately only a fraction of food functional the rest is affectively trash a company in lagos has come up with an alternative solution for handling the waste its called 8 tara and was founded by trying a tunnel. Generates 1000000 tons or tonic with talk less of what it allows importation into the countries the developing our treatment and the informal harmless if 100 dont have the knowledge they dont have the tools all the machinery to safely to cough and dismantle. The device. The terror collects discarded devices like laptops speakers and mobile phones which are then checked over of the companys Material Recovery for certainty those parts that can still be used restored and mostly denay to this charity the rest is dismantle the terror has invested in the range of machinery it allows the workers to dismantle the wastes in a way that is safe for the environment and for themselves and exhaust hood is used to contain the toxic feed. Youre not you can have so many cuts in the journey materials that are trapped there sucked out and trapped trapped inside its are diminishing pretty effectively detoxified while we dismount. So all of the glass and all of the. Plastic. Parts of being dismantled the waste is separated in shreds theyre all material salvaged such as i live in the glass and i and the companys main source of income. Businesses been going well for the company so well that they seal plants expand operations in the near future and hes happy that the items he recycles will not end up on the legal dump sites like this one. Now can you imagine growing anything on this kind of stuff ace like bush one here or could you imagine growing vegetables in it please thats cold when they on jocko months on end and the ground is as hard as a rock i guess what im talking about europes fun off on the small angry boat no engine island of spitsbergen the extreme conditions there make you apologize for research us and adventurous like Benjamin Britten his mission to boldly grow what no one has grown before thats good check it out. Finally a little light every day in winter the darkness here stretches on for months its minus 25. 00 degrees celsius and the ground is permafrost there are more polar bears than humans on spitsbergen. But one of those humans benjamin vid mark grose herbs and vegetables here a pioneering idea. This one i think looks good too and then this 13. 4 the 4th one is on the 3 of us then maher and his employee hey good harvest the crops grown in the lab as he calls this room. It has an almost tropical climate in the midst of a frozen wilderness and hes planted cress bezel and other plants so if you see that weve got the human now off to remove the tower and. Yeah yeah because we list it from 20 to 45 yeah definitely. Theyre learning to farm in these extremes by trial and error theres no experience to draw on them or came up with the idea because he was desperate for Fresh Produce one day he even hopes to grow some tomatoes they would be the northernmost crop of them on earth. Its pitch black here by 3 in the afternoon benjamin is used to that by now. Hes originally from florida but 10 years ago the ships cook washed up on the shores of the icy no region island during the dark season but so how do we cope with the light season as best a challenge but season is very relaxed dont have to do too much but when the light comes. We did very busy and you have to run all of the time. Whether dark or light vid mars business is booming hes barely able to keep up with demand and capacities are limited spitzbergen is located nearly a 1000 kilometers north of the next populated settlement practically everything has to be flown in including produce this other stuff but thats expensive and bad for the environment some greens for you. So big maher is trying to show that there are other options. To talk to those ships who also have received in this problem who do. Give in to check it out. Its amazing to. This treasure trove was given back benjamin collects the leftover plant material for composting thank you every country should take care you could just thank you. This isnt a u. F. O. Its the gardeners greenhouse in the darkness of the polar night its 20 below in here but when spring brings back the light it will turn lush and green we have some days you know over there in the midnight sun theres sun in theory 24 hours a day so it just moves around in the sky and it can get like 2530. 00 degrees in here i really like to do some root vegetables carrots potatoes would be nice if the greenhouse and its builders have achieved a certain notoriety hello my name is Benjamin Vidmar and doing this tour with you today we were nearly every day he has a lot of curious visitors. I didnt started to save the world i didnt start it i just said you know i want to have the freshest food possible. German student helps out with planting in the garden shes a little more critical of the settlement in the far north. Its been pressing the stem i noticed its back kind of person really i dont see spitzbergen as a place where people should be living. Because its gone to such an extreme climate and its so unsustainable to live here but there will never come a time when people dont live here so i think its a very good idea to try growing your own plants here. But harbaugh says its about more than just having fresh vegetables on spitsbergen. This technique that we developed here can be used to grow food in this inner city it can be used to grow food on different islands so it has many. Applications to other places as well so if we can do it here it can be done anywhere this is the most challenging place to do it. Benjamin did not believe that if his ideas can take root in spitsbergen they could grow practically anywhere. From i see no way so africa so my the gas got to be precise where the forward station as quashing impact previously 90 percent of the island was covered with forest now only a 10th of that remains according to environmental experts trees are mostly being cut down to create farmland or. But now someone has come up with an alternative fuel source tell us more sandra village does are launching a new process in which they can tell on plant waste on dry grass into fuel pellets it is so much better than cutting down the mall. Fear done and is a small town in the highlands of madagascar it never had its own school until a Nonprofit Organization called zatanna made it possible for the residents to build one. Founder of the hanna has come to visit. Talk to me on tania revoke wants to increase environmental awareness and make sure that its established in the school curriculum. The team is prepared as serious of workshops. And the rambles on runs a course on bio char a charcoal produced from plant matter. The residents collect drawing grass and leaves press them into predict holes in the ground and carefully light them. They then quickly seal the hole to cut off the air supply so the biomass can slowly char. Writer 6 can also be used they need to char in the pit for 12 hours where the restricted air supply says it looks good but the waste from the rice harvest has charred nicely we can empty out the contents now to process it. They want to make pellets and briquettes from the coldest. They are diluted clay to the biomass to glue together so they can then need it into bio char. Its a far better fuel source than would be ferns for 10 times longer and using bio char also has another advantage. To make charcoal i usually use. You know. The small talk one from these 2 i get asked if you need to cut the ts dear dont love to go far away. The residents used to spend hours gathering firewood for cooking. People here it rice several times a day. Dr planes now cover the land where forests used to grow everything has been cut down. There are only trees in the town now which the organizations are hannah replanted. The best way to burn bio char is in special clay ovens protected from the wind. And the runnels on teaches the residents how to make them. The women are already using the ovens to cook at school. But the zohan a team wants to convince everyone that the stove like this needs just a 5th of the fuel and by using bio char instead of would the embers last even longer if the old habits die hard though Winning People over takes patience despite the many advantages what do you all know musea saves a lot of fuel you stephen. Stays inside but. Its much faster to cook. Theres a han a team is testing out a new machine that could help them produce by a char. It was highly praised by technicians from the provincial capital. The machine is supposed to press and compact the biomass in the cylinders more effectively than can be done by hand but it didnt work as hoped and still needs to be optimized. In full of it you have to clean it out every time he uses it its always blocked up because i think that is fair to make you can shoot every fun you can have in one hour. Like its more fun to do you charge for. The school is also teaching the children a few i dont know about gardening or the plants and trees here were planted by pupils on the School Garden the child plants 5 trees a year and in a way says of greenery a spring up in the middle of the drawing grasslands. Then you see you go you dont like it to be certain we can go in the field from disallows Little Cherry i forget i dont think cant have people that dont look just to mangoes because were not that many was growing even in the dry. Land certain she approved so that people didnt. Design a team wants to plant 15000. 00 new trees a year together with the people of donna. So that so few of us we are half an hour packed with lots of environmental news and yes best global practices my name is now tied with ok enjoy the show thanks by by family.
