That within 16 years the population has plummeted by half. Deforestation is one of the reasons, but a large number of the animals are also being killed by hunters orfor raiding crops. Victoria gill reports. Hanging onto survival. Zoo programmes like this preserve small populations of bornean orangutans. But in the wild, they are being pushed rapidly towards extinction. Their rainforest home continues to be cleared for agriculture and mining, but a 16 year long study has now revealed that borneos orangutans are disappearing from areas where the forest is untouched. They are being targeted by hunters. Even in the areas where we think theyre safe, we are losing them. And in some of the large populations where we have measured this loss, its 50 over 16 years. It is an astonishing decline at the population level. Even without animals being deliberately killed, scientists estimate that deforestation alone could wipe out another 115,000 orangutans here in the next three decades. But this bridge building project is a much needed sign of hope. Where the forest is fragmented by agricultural drainage ditches, a team from chester zoo and the Malaysian Charity hutan is physically reconnecting it with tough polyester straps. This remarkable footage captured by a tourist is the projects first sign of success. When these animals use their arms, they move around, they move that height, they swing in the forest canopy and thats what they rely on in the wild. The zoo has learned from that to build bridges that will reconnect that habitat, just like the ones in the zoo enclosure. To actually see them using them and moving more freely across this habitat, that is so fragmented, is a really positive sign. This is very much a short Term Solution. The long Term Solution is to reforest the area. Palm oil grown here makes its way into a huge variety of our food and other products, so conservationists are urging us consumers to check its sourced sustainably. Our choices, scientists say, could decide whether there is a future for these critically endangered apes. Victoria gill, bbc news. Now its time for the travel show. This week on the travel show. Seeing africa by train. We witnessed seven lions that were chasing a zebra. It was like a movie and this was real. The history of selfies. Selfies have a very interesting history that goes back 40,000 years. And rocking the mike underwater in denmark.

The Freedom Railway cut through more than 8000 kilometres of mountains, jungle and savannah. As it winds its way from tansey to zambias central province. But more than a0 years after it opened, it is 110w than a0 years after it opened, it is now beginning to show its age and is overdue and major upgrade. We bought a ticket and went to find out what makes the journey so unique. Im scared of using the bus because buses arent safe. The first time on the train buses arent safe.

Train line is due to open this summer in morocco. It will more than half the time it takes to travel from the the port of tangiers where you can pick up slower connections. Another key upgrade recently has been the stretch from mombasa to nairobi, in kenya. That route used to be known as the lunatic express because its construction in the late 19th century was so dangerous. Thousands of labourers died working on it. Many from malaria. Some from being attacked by lions. The 12 hour journey has now been reduced to four and a half, but at those speeds you mightfind and a half, but at those speeds you might find that any visible the game makes it slightly trickier to spot. 0ne makes it slightly trickier to spot. One of the most luxury is and most expensive rides africa has to offer is south africas blue train. It ta kes to is south africas blue train. It takes to be seven hours to travel the nearly 1000 miles from pretoria to cape town and will set you back around £900, or about 1200 us.

And in egypt, the line from cairo tracks the course of the nile river and offers excellent views of plantations and villages on the way.

This is a Country Company surrounded by water, no matter where you are you are never more than 50 kilometres from the coast. So it should come as a surprise that that it was here that a local artist was inspired to combine music and water in a way that you have never heard it for. Heard before. This is the group between music, their latest show is a four part series called aqua sonic, which explores who we are as human beings and it begins with our time in the wound. Womb. We are so time in the wound. Womb. We are so often divided by you and me, them and us, religion and different cultures, but this is something we all know about. We have our first nine months covered by this water filter so i think somehow the audience, i think they are on at least an unconscious level will have a flashback to hearing those sounds. So as performers, how does it feel when you are underwater performing to an audience . It gets really, somehow a sense of loneliness to it. There is not only a visual loneliness to see the human in the tanks, but also the sound has a loneliness to it, i think that is quite a nice idea. So, here goes. 0ne deep roof and, well, actually this is quite nice. You are doing good it is lovely and warm. Yeah, this is great. So if you take this microphone that is hanging and then you hit this bell plate, you see the one . Yes. Then you take the microphone and put it in the water. Do you hear that effect . Then you can sort of play with it. Playing music in water has two sides. 0n can sort of play with it. Playing music in water has two sides. On one side it is terrifying because also when you are singing into the water you have to have watered down your throat and if you open up you get the water in your lungs. So that is quite terrifying. So how on earth do you get musical insurance to play underwater . Well it took us ten, 11 years to make this and how come it took so long . 0k, it is something that you need to really research and when you see what other people have done and are trained, most instruments didnt sound really good, but we saw somehow a potential in this. But we also realised we had to build instruments to work in the water, so we found collaborators around the world to help us build issuance for this project. Instruments. From his studio in bath in england, matt nolan works with artist all around the world to create custom made instrument. Instruments. Create custom made instrument. Instruments. Artist. Artists. I guess somehow i become the guy people go to when they need something unusual. I was approached by, i think it was one of the production guys will aqua sonic, they needed some bespoke underwater percussion. I tried a lot of things ina percussion. I tried a lot of things in a small tank of water here and was astonished by how many things literally just go was astonished by how many things literallyjust go clunk and do anything else. All of the high frequencies that shimmer like a symbol all just disappear. With various train, we narrowed down on those instruments that were heavy and massive and could sustain and contain a certain amount of sonic energy and radio out, the water doesnt kill it too quickly. It is a lwa ys doesnt kill it too quickly. It is always good to find something that is not working and figure out how to make it work. Back in denmark am beginning to think i am a natural. Maybe move this to the window and if you hit it with a hammer you can close the sound with your hand. Another thing, if you take, there is a small stick on the top of the, yeah, exactly. And you can use that for the ring over there, with the holes in it. Thats so cool axe mac youre making music thats so cool axe mac cool . It is so cool, you have these hammers, it resonates and you can feel it in your body. It is a totally different experience than hanging a bell with a hammer. And when you have been out of order for a couple of weeks and months and when we go and we have to play somewhere and get in the tank, it feels like getting home again. Try to go down and hit may be number one and number three together. May be. Maybe. Underwater music, trickier than it appears and definitely one not to try at home. Unfortunately thats all we got time for on this weeks show. Coming up next week with the Winter Olympics in full swing in south korea, carmen heads to seoul for a taste of its strict culture. It is pretty cold out here right now, it feels well below zero, but look at this place, its so bustling you would think people would be at home with the central heating on full blast, but no, this place is really happening.
