UK Study Reveals Air Pollution's Impact on Children's Lung DevelopmentResearch shows that air pollution is slowing the lung growth of children in the UK. Scientists tracked the lung function of more than 5,000 people who were born in and around Bristol in the 1990s. Their health was assessed from birth onwards and their lungs were tested as they grew up, at eight and 15 years old and then as adults, aged 24, when their lung function should have reached its maximum.Longitudinal Study Tracks Lung Function From Birth to AdulthoodProf Ann Hansell, of the University of Leicester, who led the study, said: "Much of the evidence on health effects of air pollution relates to adults or pregnancy, but we think it's highly plausible it has impacts on growth and development of children. Those whose lungs didn't grow to maximum potential in childhood may be more vulnerable to the respiratory diseases of later life because they have a lower reserve."Dr Katie Eminson, also of the University of Leicester and a first author of the study, explained: "Lung function was measured using spirometry by trained technicians. Participants were asked to take a deep breath in, then blow out as hard and as fast as possible into a mouthpiece. A machine measured both the amount of air they can breathe out and the speed of that breath, providing an indication of how well their lungs are working."Pollution Exposure Linked to Reduced Lung CapacityThe researchers calculated the children's air pollution exposure in each trimester of pregnancy and then for each year of early childhood. This included particle pollution as well as nitrogen dioxide, a gas that comes mainly from diesel cars and fossil gas boilers.Hansell noted: "We spent literally years creating the particulate air pollution exposure estimates in pregnancy and early life, including sourcing road traffic data from Bristol city council that are not available in the national database."The researchers allowed for other factors that can affect children's health, including premature birth, breastfeeding, parental smoking and home conditions including damp.They found that breathing more air pollution during pregnancy, infancy and early childhood can slow lung development all the way up to early adulthood. The greatest impact was during adolescence, which is the time when lung growth accelerates.Health Implications Extend Beyond Respiratory SystemThose with reduced lung function face multiple health risks. "They are also more vulnerable to poorer health generally," Hansell explained. "For instance, low lung function in adults is associated with the same level of risk of heart disease as having high cholesterol. Research has also shown that people whose lung health has been affected by air pollution may be at greater risk of heart disease."An earlier study found that air pollution was reducing the growth of children's lungs in east London. There, the average nine-year-old's lungs were between 90 and 100 millilitres smaller than they should be—approximately the volume of two hen's eggs.Studies on children in Sweden showed that lung growth increased when air quality improved. Reductions in air pollution might have also allowed the Bristol children's lung growth to return closer to normal rates.Call for Action on Air Quality ProtectionEminson concluded: "While the effects in individual children are small and unlikely to have immediate clinical consequences, they shouldn't be dismissed. Because lung function tends to track from childhood into adulthood, small differences early in life may have implications for long-term health. This reinforces the importance of reducing exposures and protecting children's environments."

White House sources confirmed that the United States and Iran have reached a tentative memorandum of understanding to extend the current cease‑fire by 60 days, yet President Donald Trump has not granted his approval.Trump's Pending Signature on the 60‑Day Ceasefire MoUThe memorandum, described as a “framework for extending the truce,” is intended to buy time for formal diplomatic talks. Iran’s semi‑official Tasnim news agency reported that the text of the MoU has not been finalised, and the public will be notified once it is.Key Provisions of the Tentative AgreementExtension period: 60 days from the current cease‑fire deadline.Goal: Create a diplomatic window for “formal negotiations” on a longer‑term settlement.Status: Text still under negotiation; no official release.Strategic Implications for US‑Iran RelationsThe extension could reduce immediate hostilities in the region, but the lack of presidential sign‑off signals internal uncertainty within the U.S. administration. A signed MoU would signal a willingness to re‑engage, whereas continued delay may embolden hardliners on both sides.Potential Regional Ripple EffectsNeighboring states, especially Iraq and the Gulf Cooperation Council members, are watching the development closely. A stable cease‑fire could lower the risk of proxy clashes, but any reversal might reignite broader sectarian tensions.What Comes After the Extension?Analysts anticipate that the next 60‑day window will be used to negotiate a more comprehensive framework, possibly addressing nuclear talks, sanctions relief, and maritime security. The outcome will hinge on whether President Trump signs the MoU and how both delegations handle the ensuing diplomatic pressure.

The Lead Anthropic has released Opus 4.8, the newest version of its most advanced publicly available model, with a new 'dynamic workflow' tool. The model is available everywhere at standard pricing. The Event Details Opus 4.8 comes just 41 days after Opus 4.7 was released, a much faster upgrade cycle than normal for Anthropic. The new model features best-in-class benchmark results and improved handling of bad or uncertain data. Anthropic's early testers found that Opus 4.8 is "more likely to flag uncertainties about its work and less likely to make unsupported claims." The Data Analysis Opus 4.8 is available at standard pricing. The model comes with a new 'dynamic workflow' tool, available in research preview. Anthropic's most advanced Mythos model is still in development, with a tentative preview last month. The Impact Analysis The fast turnaround for Opus 4.8 may be in response to the chilly reception of Opus 4.7 and increasing pressure from competitors like OpenAI's Codex and Google's Gemini Flash model. The new model's ability to handle uncertain data and flag issues with inputs and outputs could give it an edge in the market. The Prediction Anthropic hinted that the Mythos preview period might soon end, once necessary safeguards are complete. The company expects to bring Mythos-class models to all its customers in the coming weeks. With Opus 4.8 and the dynamic workflow tool, Anthropic is positioning itself to compete with other major players in the AI market.

The Lease Duration Dispute A controversy has arisen regarding the length of Anthropic's lease with SpaceX, a deal that involves billions of dollars a month for exclusive use of Anthropic's Colossus cluster. Elon Musk claimed on X that the lease is for 180 days with a 90-day notice for mutual cancellation, while SpaceX's recent S-1 filing presents the deal as a three-year agreement. The Details of the Deal According to Musk, the short-term lease was SpaceX's request, not Anthropic's. He stated that SpaceX won't leave Anthropic hanging and will provide a reasonable off-ramp, but might need the compute capacity back if it gets super tight. On the other hand, SpaceX's S-1 filing confirms a 90-day cancellation notice but describes the agreement as lasting through May 2029, with a monthly fee. The Data Analysis The deal involves a significant monthly fee of $1.25 billion, as mentioned in the S-1 filing. This substantial commitment highlights the importance of the compute capacity for both parties. The Impact Analysis The discrepancy between Musk's statement and SpaceX's filing raises questions about the accuracy of the information provided. This situation could be seen as a material misrepresentation made while marketing a security, which could have implications for investors and the companies involved. The Prediction The future of the lease and the relationship between Anthropic and SpaceX will depend on how this situation unfolds. With the SEC possibly involved, the companies will need to clarify the terms of the agreement to avoid any further controversy.

The Launch of Sesame's Conversational AI On Thursday, the AI startup Sesame, co-founded by Oculus' founders and others from the VR company that sold to Meta, released a public preview of the conversational AI agents it's been developing for over a year. With its new iOS app, Sesame is rethinking the traditional AI chatbot experience popularized by apps like ChatGPT, creating one where conversation flows, even if the AI needs time to think. Reimagining AI Conversation Flow As the company explains in its launch announcement, "There's an inherent tension between replying quickly and taking the time to compose thoughtful responses. A slower response is usually more correct, but it can also feel unnatural if it takes too long." To address this challenge, Sesame claims to have built fast search and retrieval systems, so the AI can have up-to-date information, as well as technology that allows it to run multiple parallel searches while speaking, weaving those results into its responses as it talks. That means the AI will talk more like a human, even pivoting mid-sentence if need be, as it taps into newer information — as a human might when remembering another key fact or point they want to add. User Growth and Development Milestones The app offers four distinct AI agents called Maya, Miles, Simone, and Charlie, each of which have their own distinct voice, personality, point of view, and memory. Maya and Miles were previously available in Sesame's Research Preview of its technology, where they were soon accessed by over one million people within the first few weeks, said Sesame investor Sequoia at the time. (The company had then just raised its $250 million Series B from Sequoia and others and was opening up a beta.) During the beta, Sesame learned from user feedback and rolled out features such as search cards with image results for visualizing concepts, notes for capturing takeaways, a texting mode for those times when speaking aloud is not an option, and support for deep dives where you can get more in-depth results. There's also a new incognito mode for private conversations, which allows the agents access to prior context but saves nothing to memory. Transforming the AI Landscape The app, however, is only the first step toward Sesame's bigger plans for AI involving intelligent eyewear, which the team expects to launch in 2027. Before that, the agents will also learn to do more than just think with you, Sesame hints, suggesting they'll later be able to take action on your behalf — hence why they're called "agents" in the first place, instead of just chatbots. That is potentially even more interesting, as working with agentic tools or apps today requires being able to prompt for what you need and have a specific idea of what you want to happen, and sometimes, even how it should happen. A conversational agent that you could talk to naturally could help you take the next steps, without you having to perfect the command you're giving it. The Road to AI-Powered Eyewear The iOS app is out today in 39 countries, and the full experience is free for the time being. However, there still may be a short waitlist at sign-up. An Android preview is coming in the future, the company says.

The Rise of Recursive Self-Improvement in AIThe word "recursion" is the latest buzzword in AI circles. Two separate startups have taken on the name, and many more have started referencing recursive self-improvement (RSI) in their roadmaps. Like AGI before it, RSI has become a three-letter byword for a cataclysmic AI takeoff – even if there's still a little disagreement about what it exactly means.In basic terms, RSI refers to an AI system that can continuously upgrade itself. Once AI systems can manage the upgrade cycle better than humans, the process can become a closed loop, limited only by the compute power they can access, and humans are no longer necessary or even helpful.Scary or not, that's a vision that a lot of AI labs are eager to chase.Key Players Pursuing Recursive SystemsEarlier this month, well-known AI researcher Richard Socher launched the aptly named Recursive Superintelligence with RSI as an explicit goal. "Our main focus is to build truly recursive, self-improving superintelligence at scale," Socher told TechCrunch at launch, "which means that the entire process of ideation, implementation, and validation of research ideas would be automatic."A number of other prominent researchers are already chasing that same goal, hoping for a breakthrough that will make recursive self-improvement possible.One of the most prominent is Andrej Karpathy, a legendary figure from Tesla and OpenAI, who is using agent swarms to train LLMs on simple tasks for a project he calls Auto-Research. Karpathy has been unusually open about the project, tweeting about milestones regularly and making the building blocks available through a public GitHub repo. So far, the work has mostly been confined to making minor improvements on a GPT-2 scale model — as Karpathy noted in March, "It's not novel, ground-breaking 'research' (yet)" — but it's been enough to convince lots of other researchers to follow the RSI dream. And with Karpathy now working on pre-training at Anthropic, he will have plenty of opportunity to apply the idea at a larger scale.Adaption — founded by Cohere and Google alum Sara Hooker — recently launched a similar tool called AutoScientist in an effort to automate frontier training. Like Karpathy's auto-researchers, the system trains agents to make incremental improvements — but for Adaption, the goal is to make it easier to train a full-scale frontier model. If those same researchers start to push the frontier forward, the system could quickly spiral into something very much like RSI.Disarray founder Doris Xin drew more specific RSI interest when her self-trained machine learning agent took home 28 medals in a recent Kaggle competition, beating out many human-trained agents. As she sees it, the major challenge is reliability."I would argue, given infinite compute and infinite time horizon, we are already there," Xin told me. "I want to make an argument that this is not a creative endeavor, really. It's just a lot of meat-and-potatoes engineering."The Current State of Self-Improving AIThere's also plenty of evidence that the AI industry isn't very close to recursive systems in any meaningful way — and is still grappling with talking to a wary public about its progress. So Google CEO Sundar Pichai basically admitted in a recent podcast interview."It's a continuum, and we are all definitely making progress," Pichai said. "But in the way people describe RSI, that would represent a next level of acceleration and would have a lot of implications, but we aren't quite there yet."But the continuum includes an awful lot of self-improving AI systems.In January, one of Anthropic's lead programmers for Claude Code estimated that "close to 100%" of his team's code was written by the tool — a frank admission that Claude Code was literally writing itself.Just because engineers are using an AI tool doesn't mean the tool can replace them — but Anthropic seems to be getting close to replacing engineers too. In a recent survey tied to the Mythos preview, five out of 18 Anthropic engineers believed that, with harness improvements, this version of Mythos could soon substitute for an L4 engineer — a midlevel programmer who can take on involved projects without supervision.Still, there were some of the same weaknesses you might expect."Some of Claude's major reported weaknesses compared to an L4 include: self-managing week-long ambiguous tasks, understanding org priorities, taste, verification, instruction-following, and epistemics," the report reads.In other words, its weaknesses are everything involved with self-direction, which is the cornerstone for RSI. But sure, for everything else, Claude is ready to step right in.Expert Perspectives on RSI TimelinesJust like the AGI term before it, the AI industry also can't tell us how far away it is from showcasing a meaningful recursive system. When Georgetown's Center for Security and Emerging Technology assembled a group of experts to study RSI last year, the group found a major split in assessments — some expecting an imminent "superintelligence" style explosion while others expected slower progress and an eventual plateau. But all agreed that recursion made the future especially difficult to predict.Helen Toner, director of CSET and a former board member at OpenAI, told TechCrunch that simply using AI tools to do AI research isn't enough to qualify as RSI. "They're just using AI for as much as they can," Toner told TechCrunch. "And I think that is different from the classic definition of RSI, which is really that there are no humans needed."Toner pointed to a recent post by METR's Ajeya Cotra, which distinguishes different milestones on the path to the AI research takeover. One step, which Cotra calls "adequacy," would come when the system can still perform research after all humans are removed — even if the resulting research isn't as valuable or efficient. "Parity" comes when an AI-only system is as good at research as a human-only system. "Supremacy," the final stage, comes when an AI-only system outperforms a collaborative system between humans and AI.Ultimately, Cotra concludes that AI is very close to the adequacy threshold of being able to produce some work on its own — similar to the incremental changes made by Karpathy's Auto-Research system. "I wouldn't be totally shocked if you told me this milestone had already passed, and I expect it to happen in the next couple years," Cotra wrote.She was less clear on when parity will come, but once it does, she thinks it would "massively accelerate the pace of AI progress, leading to AI research supremacy within another year."The Challenges Ahead for Recursive AIWith so much of AI built on scaling laws, there's a strong tendency to think RSI will follow the same curve. Toner thinks that many of those pursuing AI research and development via RSI "think of it as a pretty smooth ladder, where you can just keep scaling up."But even if AI researchers are able to make incremental improvements like Karpathy's auto-researchers, there will be larger challenges in handing off the whole process of research. Toner put it in terms of the history of computing, which has seen human beings handing off more and more of the process while still directing things from the top."We went from machine languages to assembly language and compiled languages; you're getting further and further from the guts of the computer," Toner said. "But the human is still, in some intuitive sense, running the show."Moving beyond that paradigm will take significant challenges, both in engineering and alignment. But even with the massive investments happening, there's no infinite compute available — and the basic trade-off between human labor and machine intelligence will be hard to overcome.The Future of Recursive Self-ImprovementAs for a total recursive AI system of apocalyptic visions? The only thing researchers essentially agree on is that, like AGI, it's not here yet.

The LeadA novel featuring a protagonist whose job is taken by AI has won the Climate fiction prize. Hum by Helen Phillips, the American writer's third novel, explores themes of technological displacement and the commodification of nature in a dystopian future.The Disneyfication of Nature in LiteratureHum is about a woman, May, who loses her job to a "hum" of the title – a humanoid robot. Struggling to find work, she becomes a guinea pig for an experimental injection that alters her face so it can't be recognised by surveillance. When she gets paid for it, she splashes out on family passes to the Botanical Garden, the last remaining green space in her city. There, things take a turn for the worse.The Climate Fiction Prize RecognitionThe prize, worth £10,000, was first awarded last year to Abi Daré for And So I Roar, the follow-up to her bestselling debut The Girl with the Louding Voice. This year's judging panel was chaired by Guardian theatre critic and former literary editor of the Independent, Arifa Akbar. Alongside Kit de Waal and Friederike Otto on the panel were author Jessie Greengrass and book influencer Simon Savidge.Judges' Perspectives on the NovelJudge and writer Kit de Waal described Phillips's book as being about the "Disneyfication of nature … turning nature into a rare place that we have to pay to see". Fellow judge and climate scientist Friederike Otto added that it "tackles the central reason that nothing is done about the climate crisis – privilege", while writer Daisy Hildyard described it as "mesmerising and scary".The Author's InspirationPhillips was inspired to write the book after walking home from work one day and having the thought that she needed to buy dishcloths, before opening her computer at home and finding that dishcloths were being advertised to her. "That eerie feeling stuck with me, and I started to think about what worst-case scenarios might arise from surveillance by an algorithm."Impact on Climate AwarenessHum "helps us connect with what really matters and stops us from sleepwalking into an inevitable dystopia", said Lucy Stone, CEO of Climate Spring, which funds the prize. "In the novel, the machines themselves start to question the insane volume of advertising and the consumer treadmill, and then show the family that there are multiple different futures lying ahead of them."Future RecognitionPhillips will appear at Hay festival to discuss the book on Saturday 30 May. Alongside Phillips on this year's shortlist were Madeleine Thien for The Book of Records, Robbie Arnott for Dusk, Keshava Guha for The Tiger's Share, Susanna Kwan for Awake in the Floating City and Maria Reva for Endling.

The Rise of Heated Rivalry: From Canadian TV to NYC StageWalking into the Culture Club in West Chelsea, New York, for a performance of Heated Rivalry: The Unauthorized Musical Parody last week, I was met by three ghosts left over from when the space was called the McKittrick hotel and it hosted the immersive spookfest, Sleep No More. The first was the phantom of clever detail: cans of Athletic IPAs for sale, a cute, non-alcoholic nod to the mega-popular series' hockey setting. The second was of unnerving fright, as I realized there would be no booze at this singing satire. Would I be able to make it through 90 minutes of jokes about an overexposed Canadian gay sports romance, with zero quality guarantee and an even lower blood alcohol concentration? At least at the downtown premiere of the popular parody Titanique, long before it proved itself worthy of a handful of Tony nominations, you could stand up and order a bucket of White Claws.But then the third specter materialized, the ghost of immersion and surrender, as this very funny production completely won me over. (I've since learned that a liquor license is forthcoming.) Heated Rivalry, for the uninitiated, is a television show adapted from a series of gay romance novels by Rachel Reid, a straight woman who unwittingly launched a thousand discussions about who gets to be horny over whom, how and when. Fans of the books petitioned for a wider release of the show produced for the Canadian streamer Crave, last November and, some six months later, its formerly unknown stars Connor Storrie and Hudson Williams are in easy contention for the most photographed people alive. Heated Rivalry: The Unauthorized Musical Parody is the latest addition to New York City's musical parody cottage industry, which has led me to a theater lobby where a woman in a branded hockey jersey is telling the stranger next to her that she's seen the series "probably not as many times as you think, but still a lot".The Unauthorized Musical: A Masterclass in ParodyThere was a communal giddiness as everyone filed into the unassuming performance space, where less than 200 folding chairs were arranged around a small stage. Super-fans were giddy that their dreams were coming true, and the more reserved types, perhaps blushing at what they deemed beneath them, were still clearly enjoying themselves. I liked the TV show just fine, a bit underwhelmed at what was broadly discussed as "softcore smut" but felt more in line with the twee "naughtiness" of the romance world. I had worried a musical parody put together in a few months would be a cash-grab; plain fan service for those who can't get enough of those six novels or episodes, not jabbing at the culture so much as stroking its ego. Impressively, as written by Dylan MarcAurele and directed by Alan Kliffer, it satisfies all three camps.Framing is everything, and this romp begins with a faux earnest number, à la Waitress, where three suburban Susans detail their newfound pastime: putting their husbands to bed with some iPad time, knocking back an "Ambien margarita" and reveling in their favorite televised "boy aquarium". From there, "Main Susan" (Ryann Redmond, glorious) recaps the years-long flirtation between the feuding players, innocent Japanese-Canadian "Shane Hollander" (Jimin Moon) and brusque Russian "Ilya Rozanov" (Jay Armstrong Johnson).The obligatory double entendres (a song titled Shane Hollander, Slap that Stick! or a line, by Shane's mom, about the "heavy load" her obviously gay son carries) are expertly delivered right between earnestness and tongue-in-cheek, but it's MarcAurele's ability to mock the story's sillier elements that clinched it for me. Shane, whose thumb-twiddling submissiveness often grated me in the TV show, is played by Moon as a dopey bottom with a hopeless romantic complex. What the series plays out as a forbidden romance writ epic across timelines and borders, MarcAurele presents as Shane's borderline delusion in dealing with an uncaring dom for years on end. "I keep replaying things he said," Shane beams after a hookup, "like, 'Ass up, little whore.'" The score's best number, certainly the one best primed for cabaret nights anywhere, is Liza Minnelli's Maybe This Time send-up where Shane croons, "This fuck felt different from the last fuck. This fuck, he asked if I would stay."If reading that inspires eyerolls – totally – Moon (and the rest of the cast, which includes Cherry Torres and Ryan Duncan) are so winning in their deliveries, so in on the joke without reducing their project into one, that it's impossible to resist. As the icy-hot Ilya, Johnson has the less showy role and plays it mostly straight, which makes his song about an outcast childhood made tragic by his impossibly "big ass, cold heart" that much funnier. And, well, let's face it: Johnson and Moon are sexy as hell, and charming to boot. Kliffer's inventive staging, with choreography by Brooke and Tiffany Engen on a resourceful set by Sully Ross, goes long on bunny-hopping glee.The Off-Broadway Parody Boom: A New RenaissanceThe Canadian Kliffer, previously artistic director of famed improv spots like Second City and Asylum NYC, where he helped launch Titanique's improbable boom, later told me that these parodies rarely come together with such speed, let alone quality. He'd loved MarcAurele's Pop Off, Michelangelo! in London and M3gan spoof stateside, and had just bought into Heated Rivalry, courtesy of its amorously optimistic fifth episode, when the writer texted him with the idea. The resulting work fits attractively between the out-and-out bawdiness of the Titanic send-up and the relentless Millennial nostalgia of Ginger Twinsies, which parodied the 90s Parent Trap remake last summer, and Kliffer notes that this very queer, very funny moment downtown – which also includes Cole Escola's Oh, Mary! – points to "a little bit of an Off-Broadway renaissance."This particular renaissance seems to be defined by parodies that are loving but not saccharine, willing to mock their source material while still celebrating what made it appealing in the first place. The success of these shows suggests a hunger for theater that doesn't take itself too seriously but still delivers genuine theatrical craft. In a city where Broadway ticket prices can be prohibitive, these intimate, affordable productions offer a different kind of theatrical experience – one that feels more accessible and immediate.Cultural Impact: Beyond the ParodyHeated Rivalry exists at the intersection of several cultural conversations. The original series, based on novels by Rachel Reid, sparked discussions about who gets to tell LGBTQ+ stories and how those stories should be represented. The parody doesn't shy away from these questions but instead uses humor to explore them. By exaggerating certain elements of the original series, the musical actually highlights what made it compelling in the first place.The show also represents the growing visibility of LGBTQ+ stories in mainstream entertainment. What began as niche content has become a cultural phenomenon, with the original series gaining international attention and its stars becoming unlikely celebrities. The musical parody capitalizes on this popularity while simultaneously commenting on it, creating a meta-narrative that appeals to both fans and newcomers.Moreover, the success of Heated Rivalry reflects a broader trend in entertainment where audiences are increasingly drawn to content that acknowledges and plays with its own artificiality. In an era of heightened awareness about media consumption, audiences seem to appreciate works that don't pretend to be anything other than what they are – crafted, performed, and enjoyed.The Future of Parody Theater: What's Next?As the Off-Broadway scene continues to evolve with these clever parodies, we can expect to see more adaptations of popular TV shows and movies hitting the small stage. The success of Heated Rivalry, following in the footsteps of Titanique and other parody hits, suggests that there's a sustainable market for this type of entertainment.What's particularly interesting is how these parodies are pushing the boundaries of traditional musical theater. They're more immediate, more self-aware, and more willing to break the fourth wall than many conventional productions. This approach seems to resonate with younger audiences who are accustomed to interactive media and meta-commentary.Looking ahead, we might see parodies of other recent cultural phenomena – perhaps streaming hits, viral social media trends, or even political events. The key to success, as demonstrated by Heated Rivalry, will be balancing genuine affection for the source material with sharp, intelligent humor that offers something new to the conversation.

The prosecution: MelanieI want to live a healthier life too, but removing all plastics is unrealistic and unaffordableMy girlfriend, Amy, has become increasingly concerned about microplastics and environmental toxins, and it is starting to feel a little too much. It all began after she watched online content about how plastics affect fertility, and has escalated into a broader effort to remove anything she considers “toxic” from our home.We have thrown out hundreds of pounds’ worth of cleaning products and replaced toothbrushes and dental floss. I came home from work to find all our plastic food containers had been binned, and now she wants to discuss replacing furniture, like swapping our white plastic dining table for an oak one.In principle, I understand it will be better for us. I share her desire to live a healthier lifestyle, especially as we are trying for a baby using a donor and I will be the one carrying the pregnancy. However, the pace and the intensity of the change feels a bit unmanageable.If I pick up a plastic bottle of water, Amy will snatch it from my hands and say it’s poisonousWe can’t realistically eliminate all plastics and find alternatives overnight. Unfortunately, the world is full of plastic and so is our home: we have polyester cushions, plastic shoes and appliances that I’m not prepared to chuck out. Attempting a total removal feels financially and emotionally unsustainable. Buying a new dining table won’t be easy on our wallets.We are both self‑employed and saving for a baby, so we need to be frugal. Plastic‑free products are often deemed as specialist and it’s hard to get cheap alternatives. When I found Amy had splurged on all these organic cleaning products I was shocked, because they cost about £200.At the moment, it feels as if any “normal” behaviour is deemed to be unsafe by her. If I pick up a plastic bottle of water, Amy will snatch it from my hands and say it’s poisonous.I support her decision to live with fewer toxins, but her level of vigilance is harming our wellbeing. I want us to make healthier choices, but to do so gradually and realistically, rather than through sweeping changes that leave us feeling anxious and restricted.The defence: AmyI’m conscious of what we’re exposed to as we’re trying for a baby and I want the best for themPlastics and chemicals are everywhere. I’m not pretending we can eliminate them all, but I’d like to make some changes. I don’t think the only rational response when presented with all the information about toxins and plastics is to shrug and accept it without question.It’s not that hard to make some changes. Mel says: “Microplastics are everywhere, so where does it end?” But she should be saying: “What can we do to start?”Small changes help improve our health. I watched a documentary and it really scared me: I learned that just brushing my teeth with my normal toothbrush was releasing hundreds of thousands of microplastics into my mouth every day. These are linked to illness and altered brain functionality.Mel hasn’t heard all of the facts. If she watched the same documentary, she would feel the sameI didn’t start looking into endocrine disruptors and microplastics because I wanted to overhaul our home overnight. It was because we’re trying for a baby and that makes me more conscious of what we’re exposed to. If we have a child, I want them to have the best start in life and be as healthy as possible.Sometimes Mel acts as if I’m trying to dismantle our entire life, but I’m just trying to make things better. Switching cleaning products and replacing plastic food storage with glass will benefit us for years. When I threw our cleaning products away, it was because I had done the research and knew how much better nontoxic ones would be for us. That wasn’t a gradual adjustment, but I don’t regret it.I feel overwhelmed sometimes, but being told to “calm down” or “take it slow” doesn’t help. I don’t want to make our lives miserable. I want us to make informed choices together.Not drinking from plastic bottles is an easy change we can make, as is using better cleaning products. Mel and I need to work together on this, and active participation is important to me. If my decisions seem rash, it’s only because Mel hasn’t heard all of the facts. If she watched the same documentary she would feel the same. I don’t want to scare her, but making our home safer for our unborn child is a priority.The jury of Guardian readersGetting rid of plastic won’t make Amy and Melanie’s home healthier if they replace it with pressure and resentment. Amy’s pursuit is noble, but her cold‑turkey approach risks alienating Melanie from the cause.Estelle, 27They both want to live with fewer toxins, but Amy shouldn’t decide the pace at which they do this without agreement from Melanie. Amy throwing out all plastic containers and cleaning products without any discussion contradicts her claim that she wants “to make informed choices together”.Val, 68Life’s too short to make it hard for yourself. Carrying containers everywhere and only going to specialist retailers? No one’s got time for that when there’s work and chores to be done. Changing your life after one documentary is extreme, and Amy should consider the benefits of plastic.Ivan, 29We can’t live perfect lives, but that doesn’t mean we shouldn’t try to make better choices. I think they plan together what can change now and what can wait, Melanie might feel part of it instead of feeling it is something being done to her.Michael, 39Amy is valiant in trying to live a healthier lifestyle, but not making it a joint decision with Melanie seems to be detrimental to their relationship, and they need to be working together when they have a child. I wonder if Amy’s obsession might be masking a deeper issue.Jon, 50Now you be the judgeIn our online poll, tell us: should Amy bin her hatred of plastics?The poll closes on Wednesday 3 June at 9am BSTLast week’s resultsWe asked, should Martin stop telling his wife how to mop the floor?98% of you said yes – Martin is guilty2% of you said no – Martin is innocent
