years, we know that they may be more likely to fall victim to this scam, so we predict potentially a 13% increase in the number of people losing money to this scam, and that really concerns us because there's a lot of very vulnerable people in the age group of those who are over 75. now it's time for a look at the weather with ben rich. wet and windy weather is currently sweeping northwards across many parts of the uk. the heaviest of the rain is moving across england and wales, really poor travelling conditions with surface water and spray and potentially localised flooding. some of the rain is getting into northern ireland and southern scotland, the northern half of scotland getting away with just a few showers. that is where we will have the lowest temperatures overnight. the wet and windy weather comes courtesy of an area of low pressure which will be sliding eastwards tomorrow morning. on the southern flank of the low, we will see these south—westerly winds with gusts of maybe 60 miles per hour in the most exposed spots.

through the day, we keep heavy and persistent rain across parts of northern and eastern england. a thoroughly miserable day here. to the south of that, a mixture of sunny spells and heavy, thundery showers. to the north of that, scotland and northern ireland should brighten up through the day. and as we head into monday, we have more wet and windy weather spreading to the south. the north will turn a bit cooler.

hello, this is bbc news. the headlines: the prime minister could face a vote of no confidence as early as next week, according to a senior snp mp, as conservatives gather for their party conference. meanwhile, number 10 describes as "a politically motivated attack" borisjohnson‘s referral to the police watchdog over his links to an american businesswoman. labour'sjeremy corbyn promises to scrap the controversial welfare policy universal credit if the party gets into power.

pressure grows on president trump as secretary of state, mike pompeo, is ordered to hand over documents on ukraine linked to the impeachment investigation. tear gas and water cannon are used by hong kong police to disperse protestors holding a rally to mark the fifth anniversary of the pro—democracy umbrella movement. voting has been taking place in afghanistan's presidential election amid heavy security and bomb attacks from insurgents. the results won't be known until the middle of october at the earliest. now on bbc news, protecting our planet. how can we best protect our precious planet? climate change and pollution are taking their toll. that much is now scientifically evident. but for all the uncomfortable truth,

we hold the future in our hands. in this film, we will be exploring sustainable solutions around the globe and meeting the individuals driving change in their communities. from construction to energy to conservation, these are some of the unique and surprising ways in which people from all walks of life are working to protect our planet. for much of the year, the peruvian capital lima is covered with a blanket of dense fog. this is a teeming megacity built in the desert. it has one of the least stable water resources systems in the world, and lima's population is at constant risk of shortages. in villa lourdes, on the outskirts

of the city, abel cruz has been working to bring water to those living off the grid by harvesting the clouds. in 2016, 60 fog nets were installed in this part of lima. they provided free water to 250 families.

the water used was mainly for small—scale farming. abel lived in a slum and got tired of waiting for the water to arrive. an engineer by training, he searched the internet and connected with fog net experts. hundreds of thousands of people on the outskirts of lima do not have

access to secure supply of drinking water. they have to buy water brought in by trucks. the nets require specific climatic conditions. consistent fog, light winds, and land to site nets on. fog harvesting projects have been established in other parts of the world including southern morocco and northern chile. today, there are over 1,800 fog nets all over peru, and abel has won awards for his pioneering work. the water from the fog nets in the inland provinces of peru is being treated

and is now drinkable. and scientists around the world are continuing to develop new technology to harvest water from fog. over 7,500 miles away, across the south pacific on the tropical island nation of vanuatu, it's not a shortage of water that is presenting a challenge, it's what it washes up. the scourge of marine pollution has caused vanuatu to introduce one of the toughest plastic bans in the world. since the plastic bans started, yes, i seen a lot of changes.

big changes. it does not only affect the animals on land, or the soil, but also marine life, especially turtles and fish. to protect its reefs, forests and rivers, the nation banned single use plastic bags, straws and polystyrene food boxes in 2018. in our data from the clean—ups we've done, we've definitely seen plastic bags go from the number one item that we pick up and dropping down, and even in the last clean—up we dropped out of the top 20 in things that were picked up. this market chef was one of many campaigning for change. when you clean up somewhere like in a river or in some water, you will see that there is plastic. in december, seven more items will be outlawed. polystyrene trays for food packaging, mesh for fruit and vegetable packaging, plastic cups, plastic

cutlery, knives and forks. it's without a doubt that people have been getting used to using plastics. the challenges are there. the thing that has made it easier for vanuatu to ban is because of the plastics we have are being imported, so whether need to have good collection systems in place or we ban the plastics. with no recycling plant, most plastic ends up in landfill. currently we don't have the capacity, technology—wise, to take our post—consumer pet and turn it into brand—new bottles here in country. alternatives including traditional bags have received a boost since the ban. the plastic ban has helped us a lot. especially with the

economic empowerment. it has increased and the demand is very high. the women at home, around the towns, doing their living. it is becoming their business. there are obviously other things that you cannot ban, so the number one thing that we are seeing at the moment is food wrappers. we cannot, being a importer of food were we don't manufacture lots of things ourselves here, it's very difficult for us as a country to ban plastic food wrappers or encourage different packaging.

plastic become like a monster. if they can ban it, that would be great. i would be happy. but happy mostly for my country, mostly for my environment to be clean, and happy for nature. protecting marine life on the coastal environment for pollution is also crucial work for scientists in southern chile. each year, hundreds of blue whales migrate here in the coastal waters provide a rich feeding ground. but according to scientists at the department of oceanography at the university of concepcion, marine mammals face many potential threats in these waters. blue whales are the largest animals to have ever existed. they were hunted to the brink of extinction in the 20th century and are now an endangered species. knowing where the whales are could help keep them safe. researchers are hoping to learn more about their behaviour by developing autonomous underwater gliders that

can detect and record whale song. the corcovado gulf and the inner sea of northern patagonia is a very unique marine habitat. and we have one of the most important blue whale feeding areas of the southern hemisphere. whales inhabit this acoustic environment which is the ocean, which is a really acoustic more than visual environment. they have evolved to use sound and produce and receive sound and really depend on sounds just in the way that we depend on vision. blue whales, for example, and other whales are making very loud, low—frequency songs that travel over long distances. so really, acoustically is the only way that we can get, 2a hours a day, every single day of the year, information on the

whales' whereabouts. and really, the future of ocean exploration and observation are these autonomous vehicles. the glider dives silently to depths of up to 200 metres. its detector can distinguish whale songs from other sounds. it returns to the surface every two hours and sends its findings back via satellite link. as the glider is flying through these areas, it detects whales, and it will log the position of all of those detections. and in this case, with the glider,

we are getting a picture in real time of where the whales are, so i can be in my apartment when my office and be looking at the whale detections coming in and knowing that there are blue whales are off the island, or humpback whales in the inner sea. the team hopes this technology will be used to protect the whales. what we would like to do with an acoustic alert system is to be able to make that technology available for decision—makers so that the ships in an area would be told when whales are present and they can slow down, they can be on the lookout and reduce the risk of collision. from marine ecosystems to the urban environment, the impact of pollution and climate change is all around us.

we believe waste is waste when you waste it. but you can use it and change it. in an area in kampala in uganda, young people have established an initiative to establish new solutions to the challenge problems they face. they call it a ghetto research lab. the lab is trying to find solutions to some of the problems that are associated with ghetto communities around uganda and africa. we are trying to fight poverty and enhancing and promoting sustainability among the ghetto community. the slum area was once a rubbish dump but is now home to over 10,000 people. part of the idea behind the ghetto research lab is to get young people involved in the projects and clean up their local environment. starting the ghetto research lab came to me

as i was witnessing a number of problems in the ghetto communities especially here where we are living. we are trying to empower people and remain united, that's our mission. most of the youths we are with in the ghetto research lab are youths that have a long history. when they sit you down and tell you their story, you feel like crying. i see an organisation based on saving the environment, and it's all about empowering the youth. they come together to bring youth in the community. last year they built public toilets for the local community. we have the compost toilet, plastic management for renewable and recyclable energy. we raise rabbits and goats, and local chickens. they are all local. we are trying to also teach people how to learn urban farming in a limited space.

the lab‘s work is epitomized in one unique building. they came up with this idea of picking those up and putting them in the bottle and that bottle becomes a brick to build the house. the building contains 25,000 discarded plastic bottles. each bottle contains over 200 plastic bags, thus removing over 6 million plastic bags from the environment. the community, we empower them so that if you have your bags, your plastic ones, no, don't dump them into the drainage, just bring them to us for us to use them.

as an example of aquaponics, the malnutrition is a problem. the fishing around lakes and rivers is a problem. aquaponics combines fish farming and vegetable growing using waste from the fish as a fertiliser. it enables crops to be grown soil—free. water comes here when it's oxygenated to the fish, it's being used by the fish and it becomes toxic to the fish, so it goes to the plants, the plants absorb the acidity that is turned into nitrogen, oxygenating it back to the fish. you find families with enough fish, they don't need to go to lakes and rivers to get their fish, and they're growing vegetables alongside the fish,

leading to good nutrition for their families. the group now has several hundred members and finances its projects by donations. i would like to see the project becoming a very big project that helps not only youth, not only single mothers, not only the people living in the slums, but think about the people that, the young girls that are on the streets right now. right now in technology, i'm working on wind turbine electricity. we see that the ghetto research is changing people. it's giving people skills and giving them ideas and hope. i want to reach all the areas which are most affected by the plastics, share ideas with people from this communities and find solution to their problems. we don't have to go to the shops and markets and buy those. 0ur markets are our

dustbins down here. in this southern australian mining town, residents are working to create a model of sustainable living. they've taken an even more radical approach of the changes of their environment. 60% of the residents live underground. they are the smart ones. i'm an opal miner, been mining opalfor 53 years. so i've had a good crack at it. my name isjohn dunstan. my father, back in early 1968, he says, "i want to go there. i want to try my luck". so he shifted the whole family up here, and i stayed.

once you are used to living underground, you'll never live in a house again. you never need heating or cooling, it's peaceful. last year, last summer, we recorded 53 celsius. that's hot, that's plenty hot. most of the world's opal comes from this remote town. for decades, it has drawn miners from all over the world, but the endless desert and harsh climate posed a considerable challenge. feels like a furnace when the winds are coming from the north. could be a nuclear war outside for all i care. it's pretty much a consistent 24. a four—bedroom dugout, the two bedrooms upstairs, this is one of the bedrooms we use as a spare room. it was a mine that has been converted. could be one of the only places in the world where you can do renovations or extensions and make money rather than lose money, because we hit opal as well and you dig

deeper to get the opal out of the wall. it's obviously famous for its opal, and so really, we are probably sitting on the world's largest deposit of opal. 0ur heyday was back in the ‘70s and ‘80s. we had over 1000 miners living here. today we've only got about 100 miners left. in 2017, coober pedy introduced a new hybrid renewables project. in the last year, they powered the town with 70% renewable energy. coober pedy is pretty unique as we power our own grid and have an opportunity where we can have a massive penetration. that's pretty remarkable. and itjust keeps on getting better.

this town stunk of diesel depending on which way the wind was blowing and if you lived near the power station, you were back to working with the smoke. it was terrible. i reckon australia is one of the best places for solar panels in the world. some of the best solar panel locations. it's a very remote. one of the good things that happened a few years back, when the whole state was out of power, we were probably the only people that had power. they're paving the way for other mining towns to go off grid, as a model for sustainable living in the australian outback. over the last six months to 12 months, there's already been a lot of new people moving into town. that's what we need in town, young miners. i don't even know how people

can live in the cities. they're bloody rat races. why would you want to live there? you've got a beautiful place like coober pedy out in the middle of nowhere. no stoplights, and it's fabulous. i would never swap. never. across the world, there are people striving to provide sustainable and innovative solutions to some of our biggest challenges. high and low tech, large and small scale, they're working towards preserving the earth's natural resources and protecting our planet.

the weather has been going downhill through this evening and across many parts of the uk. the earlier satellite picture shows this curl of cloud. you can see the way it has been developing, an area of low pressure spinning up in our direction, bringing heavy and potentially flooding rain, driving northwards across england and wales through the evening and into early sunday. really strong winds towards the south. some of that rain is getting into northern ireland and southern scotland, northern scotland escaping with just a few showers. that is where we will have the lowest temperatures. but as the low pressure slides through during the first part of tomorrow morning, we will see gusty west or south—westerly winds along the southern flank, gusting to maybe 55 or 60 mph in the most exposed spots. on sunday, the most persistent rain settles across northern england. a thoroughly soggy day to come here. to the south of that, sunny spells and heavy showers.

northern ireland and scotland will have some showers, but a decent amount of dry weather and some sunshine. feeling cool for aberdeen and newcastle. as this area of low pressure clears away eastwards, notice how on its back edge, the white lines, the isobars really squeeze together. we will have another swathe of strong winds across some central and eastern parts of england, particularly down the east coast. we could see gusts of 55 or 60 mph. that, combined with high tides, could cause some coastal flooding. on monday, the area of low pressure slides away and we get a quieter window of weather. there will be mist and fog patches around to start monday, but then a decent amount of dry and fine weather with some spells of sunshine. however, notice down to the south—west, here is our next area of low pressure. more heavy rain piling in across england and particularly wales. and there is again the risk of localised flooding. on tuesday, the area of low pressure will slide eastwards and as it clears,

we will follow the isobars northwards. that is where our air will be coming from for the middle part of the week, a plunge of really chilly air, temperatures dipping across all parts of the uk. let's look at some city forecasts. and then for the end of the week, it could turn wet and windy again.

this is bbc world news today. our top stories: growing pressure on president trump as reports suggest his aides restricted access to records of calls to several world leaders, including vladimir putin. police in hong kong use tear gas and water cannon to disperse pro—democracy protesters on the fifth anniversary of umbrella movement. voting finishes in afghanistan's long—awaited presidential election. the poll has been dogged by violence and low turnout. after nearly half of the competitors withdraw from the gruelling heat of the women's marathon in doha, we ask whether the event should even have been held.
