Three oclock, three oclock, three. Im in hong kong to find out how their famous Pink Dolphins are being affected by the Fast Pace Of Development here. We meet one of asias top chefs to get a new take on traditional cantonese cuisine. Were in Northern Canada to discover how to use an iceberg to make a cup of tea. I actually know him and going underground in london, we meet the people who help to keep the trains running all night. This year marks the 20th Anniversary of the handover of hong kong to china. Since 1997, the pace of development here has been rapid, as beijing pushes ahead with its transitional one country, two systems formula. A plan that will eventually see Hong Kong Merge economically and politically with the communist mainland in 2047. But environmentalists fear that one of hong kongs most iconic creatures may not survive that long. The pink Hong Kong Dolphin was actually a symbol of the handover of hong kong from british back to chinese rule 20 years ago. But now, their future is under threat. The dolphins vivid pink colour isnt caused by pigmentation. It happens as Blood Vessels expand and contract as a result of thermo regulation. Its a system the dolphins use to control their body temperature. The dolphins are meaning good luck in Chinese Culture and also they go beyond hong kong border to chinese waters, so its sort of a unity between hong kong and china back in the handover days. So its sort of a symbol of unification between hong kong and china. Theyre also a good luck and energetic symbol. Unfortunately, you know, their numbers are in decline. So its not such good luck now. Figures from hong kongs fisheries and Conservation Department show that the numbers of Pink Dolphins here have crashed, from 188 in 2003 to only 65 in 2015. And although nobody is exactly sure how accurate that figure is, theres no doubt that numbers are falling. Ive been coming to hong kong for around 20 years now and im ashamed to say i had no idea there were dolphins in the waters here. But of course you wont find them in Victoria Harbour where the tourists are. To be in with a chance of seeing the dolphins you have to leave Hong Kong Island and go west towards the airport. Land reclamation, Population Growth and pollution are all being blamed for destroying the dolphins habitat. Huge new Infrastructure Projects like this new Bridge And Tunnel to macau may be good for the economy but environmentalists claim it is Playing Havoc with the dolphins natural environment. The Hong Kong Government has announced it will create a new 2,500 hectare Marine Conservation park in northern lantau waters to help counter the effects of building another runway at the airport. The conservationists say that the marine park is in the wrong place and wont help the situation. So, when we go out to the sea, we use a long lens to take high quality photos, as you see, because there is the information we used to identify the dolphin, just like the fingerprints on your hands. Like this one, there is a round tip and a big notch. So from this one we can know exactly this individual has been seen, when and where. We need at least 2,000 dolphins to sustain the long term survival. But in the current situation, no matter how many times we run the simulations, the population is doomed to extinction. So thats a very worrying scenario. What needs to be done . What we are proposing is, protect what is important to the animals first. Now, its notjust about quantity, about how many kilometres square of habitat is being protected but also where it is protected. Those core areas should be highly prioritised areas to be protected in terms of stopping the development, lowering the fishing effort. Basically reducing the pressure on the animals. So, give them a place to survive. Well, determined to try and see some Pink Dolphins, i headed to lantau with an advocacy and Ecotourism Group called dolphin watch, who have been working to promote Marine Conservation here for two decades. Many of the dead ones that are found every year are juveniles or babies. Im going to show a dead dolphin. If youre very sensitive, then you may wish to not look. Just looks like its sleeping. So, what could have happened to this dolphin . 0k, theres no crisscross scarring, it didnt drown in a net. What are we going to see today . Are we guaranteed to see dolphins . No, no. Its a 97 success rate and if we dont see any then people will get to go again free, assuming they have the time here, but thats a pretty rare occasion because after 20 years of doing this we have a pretty good idea where the dolphins will be, given the wind and rain and time and tides, but they are wild animals so we cant make promises. Youll see lots of garbage, lots of concrete, lots of boats and hopefully lots of dolphins but, you know, i have to lower expectations because some days it just doesnt happen. I really hope we see a dolphin. The conditions are in our favour, it isnt too windy and where we are now in the waters is near the mouth of the river so the sea isnt too salty. This is their usual habitat, this is what dolphins like. For a while while theres nothing and then as we head into the western waters of lantau island, we suddenly get lucky. Oh, gosh, theres one over there oh, i missed it. Got to be quick. Its a pink one, is he going to come up again . Yep. Yep. Yep oh, no, no. Three oclock, three oclock. 0k, over there people love concrete here. Where is the Tipping Point where you say the dolphins are no longer sustainable, if you like . And even if they are, the gene pool is going to be shrinking with fewer and fewer dolphins so, by the time you list something as endangered, its quite often too late. As a cosmopolitan city which is very wealthy, we have the resource to make a balance between development and conservation of the environment. We can do both. We have to strike a balance. We can have all the development that we want but at the same time we also need to build up the capacity for the dolphins to withstand all the threats. We use the dolphin as the mascot, the symbol of the handover so its our responsibility to ensure that they will be here for a long time, notjust for us, but for the next generation and future generations to come. Time now for the last in our series of films looking at the people who keep london moving long after most people have gone to bed. And this time we meet latoya, who works overnight at one of the capitals busiest tube stations. My name is Latoya Raymond and im a Customer Service assistant here at the london underground. And i work for the infamous Oxford Circus station. Since the launch of the 24 hour night tube last year, we actually run 2a hours on fridays and saturdays. My role begins the minute you walk through the station and if you need assistance along the way, anywhere, im here. Thats what were here for. Thats fine, if you want to touch your 0yster card. 0n there . Yeah, thats it. There you go, my love. Sound result that, for you. And thats done. Thanks so much. Youre welcome, take care. At night, this is where Oxford Circus comes alive. Central london comes alive during the night. Everyones coming out, everyone is going out and having a great time, especially on fridays. You finish work, you dont want to just rush home, so they take advantage of the nightlife, they take advantage of the pubs, the fact that we have 2a hour services. People enjoy it and the atmosphere is always amazing. Its great. I am a people person, ive always been a people person. So you are the actual monopoly man it is fun, it is absolutely fun. So weve done all the 26 pubs. 0n the Monopoly Board . Yes. They come down the stairs singing. Wejoin in i dont know how youre still standing. Take care. Along with persons that are going out, having fun, going to clubs, we have persons who work and these pubs. I actually know him. Im sorry, i have to run and hug him. Now they can just come through and go home. If you can imagine working throughout the night and then having to wait another two hours for the trains to start running, its not nice. We go out as well, you know, we arent all about work, work, work. Were a great bunch, we get on. This is a family. Where did you go . Yeah, there is no more trains for the bakerloo. At nights, at the moment, we only have five lines that are running. So the problem with that is, most persons, they arent quite aware of what lines are running and how to get home. So again, this is where knowing the job, knowing the stations and knowing how to help persons. We have all the resources we need to make sure that we can get everyone home. So now that the last bakerloo line has left, its time for us to shut the gates so no one else can enter. They can always use the northbound or southbound Victoria Line or the central line if they need to get home but for tonight, theres no more bakerloo line trains. Stay with us because still to come on this weeks show. Coming up next, we eat out here in hong kong with one of asias top chefs. Chrysanthemum is not traditional for this dish but it really as a nice floralness and we got this inspiration from having snake soup in hong kong. And head to the far north of canada to meet the local people who survive some of the harshest winters on earth. The travel show, your essential guide, whether youre heading. Up next, heres another in our series of films to mark canadas 150th birthday this year. And this week, were off to the far north of the country to meet some of the people who live in the town of qikiqtarjuaq, inside the arctic circle. Well, to finish off this week were heading back to hong kong, a melting pot of cantonese and western cultures and an amazing place to visit if you love food. May chow was voted asias best female chef earlier this year and she is building a reputation as the Driving Force behind a new generation of chefs who are specialising in whats being called neo cantonese cuisine. We were lucky enough to go behind the scenes at her happy Paradise Restaurant in hong kong to watch her cook one of the most popular dishes. Today were going cook for you a three yellow wine chicken. So basically its originally a hong kong dish but at happy paradise we do neo Cantonese Food so were going to do it with more cantonese techniques, having a bit more refined. What we have here is a local breed three yellow chicken. Weve already slow cooked it. For the breast, weve cooked it at 58 degrees. For the thigh, weve cooked it at 83 degrees and for the feet, just a little garnish, because Chinese People dont did nost to tail first. Nose. Were going to do a rice on top with seasonal mushrooms, a little bit of Chrysanthemum Butter just to lighten it a little bit, to make it more floral and its going to be finished with a shaoxing broth. Were going to put the chicken in. Its already fully cooked so what were really doing is reheating it. Were going to start the broth. This broth is shiitake braise. You can really smell a lot of Shiitake Mushrooms in there. We also have shaoxing wine. Shaoxing wine is the most commonly used cooking wine for Chinese People but when you cook it with Something Like yellow wine chicken, were quite aggressive with adding the shaoxing wine. Were going to stir fry the mushrooms. In cantonese terms, its actually called chicken mushrooms. So thats why were adding it as well. Were trying to get a bit of colour. Then were going to add, this is really nice, this is the Chrysanthemum Butter. Thats going to add a really nice floralness to the fried rice. Were layering the flavours into the chicken. Just a little bit more of that shaoxing wine. So thats where well put aside for garnish. Just going to chop the chicken. The chicken should be ready. So were going to take the chicken out. Now werejust going to ladle the rice on top. Now were going to garnish with a bit of chrysanthemum. It isnt traditional for this dish but it really adds a nice floralness. We got this inspiration from having snake soup in hong kong. The Chrysa Nthemum also represents chicken feathers. And then, table side, we garnish with the soup. So this is our version of yellow wine chicken. Refined Cantonese Food with super comfort levels. Well, thats all we got time for in this edition of the programme. Coming up next week as pakistan prepares to mark 70 years of independence, we go to karachi to get a taste of life in the city. Theresjust so much more to karachi than we know. It has depth in terms of the people who live here, the cultures that exist, the lifestyles, the architecture, theres so much to see. Well, i hope you canjoin us for that if you can. Dont forget, if you want to join the rest of the travel team on theirjourneys, in real time, you can sign up to us on our social media feeds. All the details should be on your screen 110w. But until next time, from me, Carmen Roberts and the rest of The Travel Show team here in hong kong, its goodbye. Hello there. Many of us have had more than ourfair share of wet and cloudy weather of late, but that certainly hasnt been the whole story. Monday brought some sunshine for many places. That was the scene across the scottish islands. The sunshine was not shared out equally though. Suffolk seeing a lot of cloud. Many eastern areas had rather cloudy conditions. 0ut west, in the atlantic, theres another lump of Cloud Hurtling its way in, thatll bring some rain on the wednesday but for tuesday we are between Weather Systems and that means actually a fair amount of fine and dry weather in the day ahead. Where it has been so cloudy across Eastern England and eastern scotland, that cloud will break up a little bit. There will be more in the way of sunshine. Could just see the odd shower breaking up across the south west and south wales later in the day. In the sunshine, this is problable where well have the highest temperatures 2a, maybe 25 degrees. Certainly a little bit less cool than it was on monday, across the south east and east anglia, because there will be more sunshine. Through north wales, northern england, it should be fine, some sunny spells. Clouding over a little bit in Northern Ireland later in the day and maybe a shower for scotland. Most places dry, if a little on the chilly side, close to the east coast, 1a degrees in aberdeen. Most places will have a fine evening but things then begin to change. Into the early hours of wednesday, well see quite a band of rain working in across Northern Ireland, south west scotland, wales and the south west, courtesy of an area of low pressure. Quite a deep low, actually this is not a usual Weather Chart for this point in july. Closely squeezed isobars, that means some fairly strong winds and weatherfronts, bringing a band of rain eastwards, across the country. Especially across the northern half of the british isles, this rain will be quite heavy. It will go on for quite a few hours, as well. Not as much rain getting across into the south east. And then for the south west, wales and Northern Ireland, later in the day, things will brighten up with some spells of sunshine. Those blustery winds making it feel cool. 18 21 degrees. And although the weather front responsible for the main body of the rain will clear away to the east, this area of low pressure is still close by on thursday and that means very strong winds, especially up to the north west. Therell be some heavy showers here, as well. Drier, brighter weather towards the south east. Just 15 degrees in glasgow. Maybe 22 in london. We stick with that blustery theme as we head to the end of the week. Some spells of sunshine on friday. Some showers as well. Highs of 17 22 degrees. As we head towards the end of the week, a cooler, fresherfeel. Yes, therell be some spells of sunshine but some heavy blustery showers as well.
