by a man called michael wrenn, this is him with a group called generation identity, a group the government says promotes damaging and extreme views. michael wrenn ran their rural division in the south—west. so, is british revival simply a front for the same extreme views on immigration that generation identity has? british people are slowly becoming a minority in their own country. it's the way generation identity may choose to portray it that i don't agree with. are they markedly different though, if we are honest? we are in the same general ballpark, but that could be said about a lot of groups. the government's advisers, the commission for countering extremism, says british revival is a frightening of hateful extremism. when countryfile approached facebook with its finding, they closed british revival and the michael wrenn‘s pages. you can see charlotte's full

report on countryfile on bbc one tonight at 6.15pm. thousands of lego enthusiasts have descended upon finland for the country's largest ever building brick convention. fans young and old pitched in to create a mass city made from the iconic toy, which was constructed by 1,500 builders. also on display at the helsinki centre was a life—size bust of president trump and vermeer‘s painting girl with a pearl earring also had the block treatment. now it's time for a look at the weather with phil avery. after a wet and windy night in many parts of the british isles that will continue for a large part of the morning. this area of low pressure isn't as much of an issue across scotland and

northern ireland. a bit of sunshine also in south—west england and parts of wales, but the rain is ever there in parts of the north midlands and the north—east —— the north—east of england. watch out for strong winds in the north—west and along the norfolk coast, the could be issues there of flooding. it will be a crisp start to the new day monday. looks as though we will see a new area of cloud, wind and rain spilling its way into the south—western corner of the british isles and on into wales and the midlands. the further north and east you are, the drier the day will be.

hello this is bbc news with ben brown. the headlines: further promises to deliver brexit are expected this morning as the conservative party conference gets under way in manchester. public services will also be on the agenda as the government makes promises to invest in hospital projects across england in the next decade. parents are urged to have conversations with their children about organ donation in the hope that more young people willjoin the donor register. police in hong kong fire tear gas and pepper spray at anti—government protesters who have ta ken to the streets in the lead up to the 70th anniversary of communist rule in china.

wales are taking on australia in the rugby world cup. wales lead 26—25 with ten minutes to go until the whistle. now on bbc news it's time for 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 have 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. hello. i have the picture to remind me that there are 48 flood warnings and 222 flood alerts at the moment. what sort of regime do we have? a

really wet one. that is what some of you will be stuck with for the rest of the day. there will be some sunshine in the mix under wind. it continues to be wet across parts of the north of england, the scottish borders. quite a bit of rain across the heart of england over the last couple of hours. following on behind, it won't be a dry tail by any means. especially anywhere near this portion of the front that hangs around with intent. 20—30 millimetres of rain across the northern parts of england, the north midlands this afternoon. where is the sunshine? eventually, south—west england, wales, northern ireland, parts of scotland, too. still relatively mild. we can get to 19 or 20. this turn of events with the wind flicking run to the north—west is still pretty strong and quite gusty, up to 50 miles an hour. i could pile up the water along the

norfolk coast. later on this afternoon and this evening, high tide is about eight o'clock, so they could be some coastal flooding. 0nce that system moves away the skies we re that system moves away the skies were clear. it will be a crisp, dry start to the new day on monday. make the most of it because there is more wind and rain, a rerun of what we have just wind and rain, a rerun of what we havejust done, heading into wind and rain, a rerun of what we have just done, heading into the south—western corner. that will move up south—western corner. that will move up into wales, the midlands and many of the southern counties of england. generally speaking, the further north and east you are, equips start. temperature is just north and east you are, equips start. temperature isjust a bit back at 16 or 17 degrees is a high. 0n back at 16 or 17 degrees is a high. on tuesday, the same low pressure still with its fronts all over england and wales. the rain easing in the north of england and wales eventually. scotland and northern ireland, a crisp feel about the day.

highs of only 9 degrees. it is that regime that winds out because the flu along these isobars from north to south eventually plunges cold air down and across us. by the middle pa rt down and across us. by the middle part of the week, drier, brighter, but noticeably colder by day and by night. that a.

this is bbc news, i'm ben brown. the headlines at 11. as the conservative party conference gets under way in manchester, the prime minister defends his own use of language in the brexit debate. i certainly think everybody should calm down. and i certainly think... including you? i think i've been a model of restraint. but i think everybody should calm down. public services will also be on the agenda as the government makes promises to invest in hospital projects across england in the next decade. parents are urged to have conversations with their children about organ donation in the hope that more young people willjoin the donor register. hong kong police fire tear gas and pepper spray at anti—government protesters who have ta ken to the streets in the lead up
