hello, this is bbc news with shaun ley. the headlines: the eu's lead brexit negotiator, michel barnier, says the uk has now reached a moment of truth. he rejects borisjohnson‘s demand for the irish backstop to be scrapped. the prime minister's

message to his own party — he tells tory rebels to back him or side withjeremy corbyn. a close ally of the prime minister says he'll have the support he needs. i believe that a majority of mps in the house of commons this week will back the prime minister because we know the prime minister is making progress with our european friends and allies in order to ensure a deal. pro—democracy activists in hong kong target the city's airport after a night of violence in which dozens of people were injured. police describe the lone gunman suspected of carrying out the second mass shooting in texas in a month asa " ' now on bbc news, protecting our planet. in a series of documentaries we will explore how best we can protect our precious planet, exploring sustainable solutions around the globe. 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'll be exploring sustainable solutions around the globe and meeting the individuals driving change in their communities. from housing to energy and fashion, these are some of the unique and surprising ways in which people from all walks of life are working to protect our planet. —— from construction to electronics and food. nested in the jungles of bali, a surprising material is being using bamboo.

architects and designers are creating buildings that embrace the national world. the perception of bamboo in asia over the last 100 years until today has been quite low. it is considered a very humble and impermanent material = because it can be eaten by insects if not properly treated. when it is treated it is protected from the rain and sun. laura harvey is the founder of a charity that has been pioneering the use of bamboo into new and ambitious constructions. our organisation is called ibuku. it's a reference to mother earth. it means mother earth in asian culture. bamboo is found in asia, australia, north and south america, and sub—saharan africa. according to the guinness book of records, it's the fastest growing plant on the planet. there are thousands of species of bamboo around the world and hundreds here in indonesia. the structure of this house,

it's six storeys tall, 700 square metres, four bedrooms, it has a big, open living room, a kitchen and a dining room nestled right beside it. those are open—air and it lets the breeze come right through. giant bamboo is an evergreen species that is harvested between three and five years into its growth. the team at ibuku treat it before it is used in construction. in our team we have about 20 designers and another 90 people working together in a workshop nearby to prepare the bamboo material, constructive material and get the building built. my name is david and i'm a senior architect.

the construction industry, the design world, relies on materials that bend to your will. people love plastic, you can make whatever shape you want out of it, you can mould it, the ultimate vanity. bamboo has incredible strength. an engineer i know compares it to carbon fibre because of the way the long fibres result in strength and flexibility, which is important. it's also critical in ea rthquake—prone situations. the bamboo structure will kind of dance and bend long before it cracks under pressure. now we have it properly treated, we hope people realise you can take advantage of the flexibility and incredibly efficient growth. while laura and her team work to change perceptions of bamboo and its use in construction in indonesia, injapan‘s capital city, entrepreneurs are also

trying to challenge ideas about the materials we use and the longevity. at this cafe, people are learning how to repair their electronics instead of throwing them out. in a few hours, mobile phones, chargers and radios are being saved from the rubbish.

japan has the second highest volume of e—waste in asia, according to the united nations university global e—waste monitor, with 2.1 metric tons generated in 2016 alone.

in the northern italian town of modena, massimo bottura is taking his fight around the world. he isa he is a three starred chef whose re sta u ra nt he is a three starred chef whose restaurant has been ranked 51 on that list of best restaurants in the world.

in 2016, bottura and his wife created food for soul, a non—profit organisation that establishes refottorios, establishes refettorios, community kitchens, to fight food waste using surplus ingredients and world—class recipes. there are currently three refettorios in italy and others have been established in london, paris and rio dejaneiro. we are developing a sd image

of how we see italy, the culinary world, the future of food, ourselves, our identity, and forming a circle that is getting larger and larger. the garden is a little project because i am collaborating with a local high school, it's an agricultural high school. it's really overwhelming, the emotion that i have working with them, and i am so curious to see the results. and that's how the last 25 years have gone by in a flash, because one thing leads to another and we can ride off each

other‘s enthusiasm, which can be very dangerous but fortunately we have two children and one of our children has a disability, and this disability has also given us really strong roots, kept us very grounded. massimo bottura and lara gilmore are also ambassadors of tortellante, a fresh pasta lab where traditional keepers of the tortellini craft pass their knowledge on to teenagers living with autism. bringing these young adults together and teaching them a skill that they can learn, where they can have an identity, they can have an occupation, not only of their time during the day but also to have a profession, a skill that many other people don't have, my son charlie is able to make tortellini 100 times better than i am. they see their skills being put to use and at the end of two hours or three hours, or a four—hour morning they've been making tortellini, they look at this

incredible production they have made, all these beautiful handcrafted unique, small bites of love. massimo employs the same philosophy in his three—michelin—starred restaurant as he does in his refettorios. nothing goes to waste.

in some parts of the world, people are rapidly changing the way they produce food. just off the coast of south korea, onjeju island, farmers are having

to adapt to climate change by growing new crops. rising temperatures have caused parts of the forest here to die and many species are now endangered. jeju island was once an independent kingdom, tamna. today it is a special autonomous province, known for its volcanic rock formations and its dramatic coastlines. it has been estimated that global warming will cause korea to turn into a subtropical climate by 2070. many locals are concerned about the potential impact on the island's unique climate and culture.

because of rising temperatures, farmers like kim are now cultivating pa payas, bananas, sugarcane and avocado. the banana tree yields

about 55lb of bananas. while a papaya tree can produce around 88lb of papaya. tera kim teaches dancing to remind people of their connection to nature.

whilejeju island is facing a rapidly changing climate, the erosion of the antarctic wilderness is presenting scientists a new set of questions. they are attempting to determine the age of the ice sheet, to track antartica's glacial history. antarctica contains enough sea ice to raise sea levels by about four metres. where we are working, in the amundsen sea, has some of the fastest changing ice. the amundsen and glaciers that contains them are of particular interest to scientists around the world because of this rapid change. in order to understand how the ice might behave in the future, one of the crucial pieces of information is to understand how

it behaved during past times of warmer conditions. drilling kilometre—long sediment and rock cores into water thousands of metres deep is uncovering vital information. hidden within hundreds of metres of core are microscopic treasures. the continent—scale ice sheet has grown and shrunk over millions of years. but as a way to determine when that has happened, we need a time machine or a record of how it has behaved in the past. 0ur sedimentary deposits and our drill core provide that time machine. but in order to determine the exact age, we use tiny microscopic fossils made of glass, and these organisms give us a key to understanding these past records. these are known as diatoms.

diatoms are photosynthetic algae that live around the world in watery environments. they are very small, typically in the order of 50 microns. 0ne micron is a 1000th of a millimetre, so very small, we need a microscope to study them. under the microscope, most diatoms look like small discs of silica with very fine holes that are arranged in very ornate patterns. in antarctica, diatoms are of particular importance for dating rocks, or determining the ages of ancient rock layers. the history of the antarctic ice sheet is recorded in these rock layers. antarctica is a vast continent. we know surprisingly little about its history, and these glassy organisms are one of the primary ways in which we can date the rocks

from around antarctica and determine the evolution of the ice sheets through time. these tiny glass fossils are the time travellers of antarctic science. they help scientists to understand the history of this vast continent and to predict the future of antarctica's ice sheets in what is projected to be a much warmer planet. 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 are working towards preserving the earth's natural resources and protecting our planet.

good morning. this time last week we we re good morning. this time last week we were preparing for temperatures to reach 33 degrees but this sunday a different feel to the weather, cooler air pushing down from the north—west and with that we are seeing spells of sunshine but some showers as well and some of those will be heavy, cool air coming down from the north—west, we are tapping into yellow and even blue shades across the uk and with that we have showers from the north—west starting to push in across scotland into northern ireland and northern

england, wales and the midlands as the afternoon wears on. to the south not as many showers, but were at the showers crop up in scotland some will be heavy and thundery, even in the sunny breaks between the showers temperatures just 1a or 15. northern ireland will see more cloud and showers in the afternoon, showers in north england and wales, some clipping into east anglia but further south not as many showers, good spells of sunshine, temperatures 21 degrees. tonight that band of showers in northern ireland will work its way into scotla nd ireland will work its way into scotland and northern england, away from these areas it's dry and under clear spells it will turn chilly, in towns and cities, some spots in this countryside will be 4 or 5 degrees. high pressure to start monday meaning it will be fine and right

for the most part but this frontal system for the most part but this frontal syste m fro m for the most part but this frontal system from the west will bring changes, gradually through the day you can expect more cloud, for western wales and the south—west of the odd spot of drizzle, for northern ireland and scotland in the far north of england, some rain but eastern scotland likely to keep hold of sunshine, it might feel a little milder than today. on tuesday still quite a lot of cloud, some outbreaks of rain, the heaviest showers in the far north—west and windy in the north later on tuesday, so a little bit less cool but that doesn't last, from midweek onwards we see more rain sweeping south—east and those temperatures dip again, mid teens across northern areas, may be touching 20 degrees towards the south.
