A report for the un says switching to a diet without meat could help slow down Global Warming. Inter is not for everyone. That is why i am here. Footballs transfer window has just closed. Manchester united sell Romelu Lukaku to inter milan for £74 million. Its exactly 50 years since the beatles walked across that zebra crossing in abbey road for their seminal album cover. Well be talking to hunter davies, author of the bands only authorised biography. Detectives have described a machete attack on a policeman in east london as frenzied, unprovoked and shocking. The Patrol Officer was stabbed several times after stopping a van in the leyton area. Scotland yard says he was seriously injured but will recover. A man in his 50s has been arrested. Andy moore is at the scene in east london for us. The latest on the Police Officer is that he is in a stable condition. He had an operation on his hand this morning. He has been widely praised for his bravery and presence of mind in being able to tease the suspect despite being seriously injured. An eyewitness told us he saw the Police Officer on the ground in the road behind me, his uniform had been taken off, he was being given cpr by collea g u es taken off, he was being given cpr by colleagues and paramedics, lying motionless at that stage, and eye said they thought he had been killed. It should have been a routine stop, but it turned into what police described as a frenzied, two minute long attack. After a brief police pursuit, a large white van was pulled over. The driver, in his 50s, became aggressive and pulled out a machete. We could see the van and the officer was there. He just got attacked and obviously me and the mrs were standing here, talking about it. We felt really sorry, not only because it was a person lying on the floor, but on top of it because it was a Police Officer, like the person who is actually responsible for our safety and stuff on the streets. As the Police Investigation began, the officer was being treated in hospitalfor his injuries. A wound to his head required stitches. He was due to undergo an operation for the injuries to his hands, sustained in trying to fend off his attacker. Police say the incident was filmed on a body worn cameras but they are still seeking witnesses. The members of the public who were there i would urge you to come forward. While weve got a man in custody, we need to get to the bottom of why this happened and the fuller picture of what happened just before and then during the attack. The Prime Minister has paid tribute to the bravery of the Police Officer. What this underscores, for me, is the bravery of our police people, who actually go towards danger to keep us safe. 0ur sympathies are obviously with the officer and his family. I think youve got to give officers the confidence that they need, that when they ask somebody coming towards them, who may be carrying a knife, which is a danger to them and to everybody around them, that they have to have the power and the confidence to do that emotionally challenging thing and do stop and search. A man has been arrested on suspicion of grievous bodily harm. Police say its not being treated as a terrorist attack. That suspect who was arrested is still being questioned. He is 56 yea rs still being questioned. He is 56 years old. The second officer in the patrol car, who made the arrest, she was a female Police Officer. Priti patel has paid tribute to the bravery of the officer injured. She said she was horrified by the shocking stabbing of one of our brave Police Officers in leyton. His courage in the face of danger shows how police put their lives on the line to protect us everyday and i wish the officer a full recovery. The attack came as figures show theres been a dramatic rise in the number of women and girls caught carrying knives in england. Data obtained by bbc news show a 73 increase in offences over the past five years, with nearly 6000 cases recorded. Youth workers say some women end up carrying weapons for gangs, because theyre less likely to be stopped by the police. Sarah corker has our special report. Manchester city centre in the middle of the afternoon and a teenager has been threatening someone with a knife. But look closely and theres a difference here. This is an 18 year old woman. She was carrying this, a 12 inch bread knife. Across england, female knife posession is rising. The first thing i would go do is run for a knife. I would go for a knife threaten, cut. It was like this mist came over me and i charged at her with a knife, stabbed her straight in the top of her head. Louise ann and teresa both lived in a world fuelled by violence and were addicted to drugs. For 12 years, teresa carried a knife. She went to prison for attacking her neighbour. I stayed in this lifestyle ofjust brokenness, in very abusive relationships to the point that my kids were taken into the care system and at that point i completely lost all hope so i started taking heroin. I was out on the streets, working in prostitution, and i used to get in a lot of fights, there was a lot of violence. Id either have a knife or a pair of scissors, something sharp. Women are often overlooked or ignored when it comes to tackling britains problem with knife crime. Its framed as a male problem. But figures obtained by the bbc show that, on average, one woman is caught carrying a knife here in the north of england every single day. In england, theres been a 73 increase in knife possession cases involving women in the last five years. Since 2014, theres been more than 5,800 cases of women caught carrying knives. Around a quarter of those involved girls under the age of 18. Unfortunately you have exploitation from the school gates. And the causes are complex. Youth workers in leeds say some women willingly carry knives to rob people. Others are being manipulated by men. They are asked to maybe be the courier of these weapons. They will agree to do that because they want to please their partner. So what we have come across are women who will hide the weapons, say a knife, ina pram. You know, which Police Officer is going to look at a female who is walking with her baby in a pram and stop and search her . In the west midlands, these weapons were found hidden in a designer handbag. Louise ann now lives in salford. She first used a knife as a teenager in london to get cash. Then, in her 20s, it was a way to protect herself in abusive relationships. I remember i used to have knives in my backpack. I used it to threaten people. Give me what youve got, take it off of them. I used to sleep with a knife under my bed, because i started to get quite paranoid, the more stuff that i done. I remember my boyfriend bought me this. He actually bought me knives. Knives got used all the time. Across the pennines in sheffield, South Yorkshire police is one of seven forces with extra powers to tackle Violent Crime. Specialist officers target known trouble spots and have a more visible community presence. I dont think it is any more nuanced for women than it is for men. It is about vulnerable young people getting drawn into the fringes of organised crime. Back in manchester, the 18 year old woman seen swinging a knife was sentenced to 12 months in prison. While louise anne and theresa are both Addiction Free and coming to terms with their past. Put yourself around those positive things. If you hang about on the streets, youre going to reap destruction. Women carrying knives has often been described as a hidden problem but, with the numbers increasing, the pressure is on police to tackle it. Sarah corker, bbc news. Eden lunghy is with me. Shes part of a group of young researchers from the take back the power project on knife crime and Youth Violence who delivered a letter to number ten today calling on borisjohnson to put solving knife crime at the top of his priorities. Tell is a bit more about what you wa nt tell is a bit more about what you want the Prime Minister, the government and authorities to do about knife crime. The letter was from young people who have been working on street violence under knife crime projects in london and we are calling on borisjohnson to invite the young people who have lived experience of violence, a lot of time when the discussions are held, young people do not lead the discussion. We think this is an important way that Boris Johnson cannot just say he important way that Boris Johnson cannotjust say he is going to put 20,000 police because we dont think thatis 20,000 police because we dont think that is the only solution to solve the issue. Police can sometimes actually make matters worse. Especially with young people affected by serious street violence, affected by serious street violence, a lot are from marginalised groups. They dont feel like the police dont protect them and are over policing and it can cause a disconnect. We need to look at solutions that come from young people who have lived the lifestyle because their solutions will be a lot more radical and implement real change. And our report highlighting how many women and girls carry knives. Are you surprised . No mac. A lot of the time the discussion is focused on men and you have to remember that these men do not live in isolation, they live in and amongst women and these women can also be living that lifestyle. If young men feel like they need to protect themselves, it is not surprising that young women feel like that as well. A lot of the time the media covers women as victims but maybe they are carrying the weapons as well. When you talk about people needing to protect themselves, is that one of the principal reason is that so many young people, men and women, are carrying knives . There are a range of reasons, from just wanting to protect themselves, yes, that is one, but also not feeling safe. When you feel like the police arent there to protect you, you kind of have to want to fend for yourself. When you talk about the police, surely extra Police Officers will help counter the levels of serious crime and Violent Crime in the country which have been really concerning. I dont thinkjust adding more police is the one solution to this. There has to be a multifaceted solution, amnesties, putting young people at the forefront of discussions, and dismantling structural violence. A lot of young people are at the receiving end are from marginalised communities. I dont think the police can just solve the issue. How much of the knife crime is from gangs . I think it is hard to measure because who is defining what a gang is . It could literallyjust be a group of friends and it starts and turns into something else. The Police Called him a gang but they arejust friends. It Police Called him a gang but they are just friends. It is Police Called him a gang but they arejust friends. It is hard Police Called him a gang but they are just friends. It is hard to measure how much of it is coming from gang related matters. Do you think knife crime is getting worse year on year . The statistics seem to indicate this, we are seeing more young people dying of knife crime. |j think there has been more awareness, especially in the media, but i sometimes think it is scaremongering and putting out a perspective that there is more happening. This has been an issue for a long time and we can see from our research that this is not just happening can see from our research that this is notjust happening today, but we need to look at the root causes and how structural violence, poverty and inequality has a big impact on young people breaking news now and we are hearing from our colleagues in belfast newsroom that riot police have pulled out from the site of a bonfire in Northern Ireland because there was a substantial threat to life, according to sinn fein. Officers were attacked after going in to support contractors who were brought in to remove the wooden pallets. Missiles were thrown at police and an officer was knocked down. There are warnings that the bonfire is a risk to local tower blocks. Sinn fein has said authorities are now considering evacuating residents, and that the majority of the community do not want the bonfire. Some other news coming in from police in essex.

More on that as it comes in to us. Climate scientists are warning that High Consumption of meat and dairy produce around the world, is fuelling Global Warming. Researchers say intensive farming releases carbon into the atmosphere, helping to raise temperatures. Now the United NationsIntergovernmental Panel on Climate Change says more people could be fed using less land, if there were less meat consumption, and a switch to plant based diets. Our environment analyst, roger harrabin, reports. This alpine landscape was once covered by forest, the trees sucked Carbon Dioxide from the atmosphere and regulated the climate. Then humans cleared some of the land forfood but cattle burp methane and that strongly heats the atmosphere. This sort of low intensity grazing may produce protein from poor soil and it does have some environmental benefits but it create more Greenhouse Gases than growing plant protein. Scientists meeting here in the alps are not saying we have all got to go vegan to protect the climate, they are saying that we do need to cut down on red meat and dairy produce and shift on towards eating more vegetables. And that message may not go down very well here in a region that is so heavily dependent on cheese and meat. We need to do what we can on the land but actually its important to maintain Food Production and so there will always be some emissions on land. So in fact we have to do as much as we can in the energy and industry and other sectors as well. We need to do everything now really if we are to have any chance of avoiding the worst impacts of Climate Change. Debate here has been fraught because of the way we use the land is so complex. Among the experts recommendations are on biofuels, limiting the area used to grow trees to be burnt to make electricity. This could conflict with feeding the world. 0n deforestation, working harder to protect the trees that protect us from climate heating. 0n desertification, finding ways to feed people that dont involve degrading the soil through overgrazing. Then there is the way we eat. In the west we over consume meat, dairy. That is bad for our health, it is bad for the climate, it is bad for water, it is bad for land degradation. So if we were able to reduce our consumption in the west of meat and dairy then we could have significant benefits for the climate but also for our health. Scientists also want to stop food being discarded because wasting food means the Greenhouse Gases created to produce the fertilisers to grow the crops have been for nothing. A charity in geneva redistributes waste food. Here they are taking stale bread and turning it into new cookies. This avoids having to produce fresh flour to make the cookies. Here is a positive sign, these peat moors in the north of england were previously drained so animals can graze. When peat is exposed to the air it gives off Greenhouse Gases, so now they are blocking up the channels to soak the peat again. One of the easier options in what for scientists has become an increasingly desperate attempt to stop the planet overheating. Roger harrabin, bbc news. And later in the hour well be hearing from the president of the National Farmers union for her view on todays recommendations. The headlines on bbc news. The Prime Minister praises the bravery of a policeman left critically injured in a machete attack in east london.
