Poisons Fit For Eating?

The manufacturers have claimed that the herbicide Roundup, whose active ingredient is glyphosate, is "safe enough to drink", and many people are naive enough to believe this.

However, there is mounting evidence of the harm glyphosate-based herbicides do, and concern has been expressed that their toxic effects have been underestimated or played down by the agrochemical industry and international regulators.

When DDT was launched in the 1940s in the aftermath of the Second World War, it was also said to be "safe to eat", and an entomologist trying to sell it to an African tribe apparently gave a practical demonstration of this ill-founded assumption. Watch the clip from the 1946 selling campaign on Youtube. Horrors. The poison is sprayed liberally into the air and on the ground with local tribespeople sitting close to the action. No-one has a protective mask or clothing. The pictures of the entomologist eating his DDT-laced porridge are beyond belief, although the scene may have been staged without the actual poison for the sake of filming. If it really happened, it would be interesting to know what happened to the protagonist later in his life. Unnervingly, the whole film, 'DDT versus Malaria', (viewable on the Wellcome Library), is an unashamed, contrived piece of propaganda for the DDT programme against malaria in Kenya, with the tribe eventually accepting the spraying of their homes, and the prime opponent of the programme being taught his lesson when his child falls ill 'after the malaria epidemic is over'. But the tribal members and their chief who are depicted as initially rejecting the poison were proved right in the long term. DDT was banned from production in the United States in 1972, and banned from agricultural use worldwide through the Stockholm Convention of 2001, with the provviso that it could still be used under controlled conditions against malarial mosquitoes, although alternative methods for combating them have been proposed in order to eliminate the use of DDT. 

DDT is still around and in the food chain, despite the bans all those years ago. No doubt glyphosate herbicides will be banned in due time - probably when the manufacturers ahve a substitute they can sell as 'safer'. How much damage do pesticides have to cause to the environment and human health before they are totally withdrawn, or at least strictly controlled? Or do we really have to keep repeating the cycle of waiting thirty-odd years for the manufacturers to develop new poisons to replace them, with new reassurances that this time these really are safe to ingest, and so on and so on, ad infinitum?

Go Hvar, go ORGANIC!

  • Fire chief says summer, the UK’s hottest on record, was ‘one of the most challenging for wildfires that we’ve ever faced’

    Ten English fire services tackled a record number of grassland, woodland and crop fires during what was the UK’s hottest spring and summer on record, figures show.

    In total nearly 27,000 wildfires were dealt with by fire services in England during the prolonged dry weather of 2025, according to analysis by PA Media.

  • I’ve spent six years writing about environmental justice. The uncomfortable truth is that we’re not all in it together – but people power is reshaping the fight

    It’s been another year of climate chaos and inadequate political action. And it’s hard not to feel despondent and powerless.

    I joined the Guardian full time in 2019, as the paper’s first environmental justice correspondent, and have reported from across the US and the region over the past six years. It’s been painful to see so many families – and entire communities – devastated by fires, floods, extreme heat, sea level rise and food shortages. But what’s given me hope during these six years of reporting as both an environmental and climate justice reporter are the people fighting to save our planet from catastrophe – in their communities, on the streets and in courtrooms across the world.

  • Bereaved relatives say delays over risks at village churchyards are causing distress and call for council action

    Families of people buried in graves vulnerable to coastal erosion say indecision over how to tackle the problem is causing them avoidable anguish about the final resting places of their loved ones.

    North Norfolk district council (NNDC) has identified three church graveyards in the villages of Happisburgh, Trimingham, and Mundesley as being at risk of being engulfed by the sea in the coming decades.

  • The bioscience startup has attracted billions in investment – and a flurry of criticism, but founder tells the Guardian plans to bring back the woolly mammoth will not be derailed

    Death and taxes are supposed to be the things we can depend on in this life. But in 2025, the American entrepreneur Ben Lamm sold much of the world on the idea that death did not, after all, need to be for ever.

    This was the year the billionaire’s genetics startup, Colossal Biosciences, claimed it had resurrected the dire wolf, an animal that disappeared at the end of the last ice age, by tweaking the DNA of grey wolves. According to the company, it had also edged closer to bringing the woolly mammoth back from the dead, with the creation of genetically engineered “woolly mice”.

  • Wildlife trust is raising funds to buy largest piece of land in single ownership to come up for sale in England for a generation

    “We’ve lost so much,” says Mike Pratt, reflecting on Britain’s nature crisis. “We’re getting to the point where if we’re not careful, children in the future won’t know what a hedgehog is. They won’t have encountered one.”

    Pratt, the chief executive of Northumberland Wildlife Trust, is speaking on an unseasonably sunny, calm, blue-skied December day surrounded by ruggedly beautiful, spirit-lifting countryside.

  • From moules marinière to scallop, bacon and garlic butter rolls, here’s how to cast your culinary net wider and embrace more sustainable species

    For a nation surrounded by water, Britain’s seafood tastes are remarkably parochial – we mostly eat cod, haddock, salmon, tuna and prawns. But with a huge range of species out there, making the decision to swap the “big five” for more sustainable options could be a good new year resolution to aim for. Here are five species to consider – and if you’re worried these won’t taste as good as cod and chips, we’ve rounded up a selection of top chefs to tell you how to make the best of what could be on your plate in 2026.

  • Guardian US readers share how global heating and biodiversity loss affected their lives in ways that don’t always make the headlines

    The past year was another one of record-setting heat and catastrophic storms. But across the US, the climate crisis showed up in smaller, deeply personal ways too.

    Campfires that once defined summer trips were never lit due to wildfire risks. There were no bites where fish were once abundant, forests turned to meadows after a big burn and childhood memories of winter wonderlands turned to slush.

  • When developers began circling Espíritu Santo island in the 1990s, a private conservation effort saw them off. But today the Unesco site faces a new threat: mass tourism

    On a clear day over the Sea of Cortez, Espíritu Santo looks untouchable. Turquoise water laps at the shores of the island’s rocky coves; whale sharks cruise past snorkellers; seabirds caw over ancient cliffs. The pristine island and its Unesco-protected surroundings – informally called “Mexico’s Galápagos” – are a cocoon of biodiversity.

    Yet an increase in tourist numbers has led to growing unease among the island’s longstanding stewards, as environmentalists report a decline in the area’s marine life and call for stricter regulations.

  • Since Zack Polanski took over as leader, the party has doubled its membership and its four MPs want to take on Reform’s anger and build community spirit

    “Someone has to be out there making the narrative for social security. Someone has to fight the corrosive attitudes to people on benefits,” says Siân Berry, who has just finished her first year as a Green MP in the House of Commons.

    She is speaking to the Guardian in her Brighton constituency office, formerly occupied by the legendary Caroline Lucas who flew a lone flag as the only member of parliament for the Green party for 14 years.

  • Sve više dokaza upućuje na to da teška bolest desni, parodontitis, može doprinijeti poremećajima središnjeg živčanog sustava putem kronične upale. Međutim, njegova uloga u multiploj sklerozi, kroničnoj autoimunoj bolesti središnjeg živčanog sustava, nije bila jasna. No, rezultati nove studije upućuju na potencijalnu povezanost između relativne brojnosti Fusobacterium nucleatum, bakterije koja se nalazi u ustima, i težine bolesti kod pacijenata s multiplom sklerozom.

  • Rezultati nove studije ukazuju na potencijalne terapijske učinke dihidrotanshinona I (DHT), spoja dobivenog iz tradicionalne kineske biljke Salvia miltiorrhiza, na rak jajnika. Istraživanje, koje su proveli kineski znanstvenici sa Zhejiang Chinese Medical University i Jiangsu Normal University, otkriva da dihidrotanshinon I može izazvati autofagnu staničnu smrt u stanicama raka jajnika ometanjem puta autofagije-lizosoma posredovanog sortilinom 1 (SORT1).

  • Nedavno objavljena studija bacila je novo svjetlo na ulogu proteina NSUN2 u razvoju srčane hipertrofije i zatajenja srca. Naime, istraživanje, koje su proveli kineski znanstvenici s Harbin Medical University pokazalo je, da NSUN2, član obitelji domena NOL1/NOP2/Sun, značajno doprinosi patološkoj srčanoj hipertrofiji aktiviranjem osi LARP1-GATA4, potencijalno nudeći novu terapijsku metu za zatajenje srca.

  • Gestacijski dijabetes, stanje, koje povećava zdravstvene rizike i za majku i za dijete, poraslo je u SAD-u za 36% tijekom devetogodišnjeg razdoblja (s 58 na 79 slučajeva na 1.000 poroda) i povećalo se u svim rasnim i etničkim skupinama, pokazala je nova studija.

  • Briga oko spajanja kraja s krajem stari vaše srce jednako kao i klasični čimbenici rizika za srčane bolesti, tvrdi nova studija. Naime, pokazalo se, da su financijski pritisak i nesigurnost u vezi s hranom najjači pokretači ubrzanog starenja srca.

  • Nakon traumatske ozljede mozga, neki se pacijenti mogu potpuno oporaviti, dok drugi zadržavaju teške invaliditete. Točna procjena prognoze je izazovna kod pacijenata na terapiji održavanja života. Iako funkcionalna magnetska rezonancija u mirovanju (rs-fMRI) može procijeniti neurološku aktivnost ubrzo nakon ozljede mozga, nije poznato predviđa li komunikacija između regija mozga u ovom ranom trenutku dugoročni oporavak.

  • Diljem svijeta uobičajene infekcije postaju sve teže za liječiti. Novi pregled prikazuje otrežnjujuću sliku globalne antimikrobne rezistencije (AMR), prateći kako se bakterije i gljivice razvijaju brže nego što medicina može reagirati. Uspoređujući podatke o rezistenciji iz više sustava nadzora, znanstvenici su identificirali alarmantne trendove: rastuću otpornost na antibiotike posljednje linije, regionalne nejednakosti i brzo širenje rezistentnih gena putem globalnih putovanja i poljoprivrede.

  • Nova analiza više studija otkriva da proizvodi od kanabisa koji sadrže relativno visoke razine psihoaktivnog spoja tetrahidrokanabinola, obično poznatog kao THC, mogu pružiti kratkoročna poboljšanja boli i funkcije. Međutim, pregled je otkrio da proizvodi na bazi THC-a dovode do povećanog rizika od uobičajenih štetnih simptoma poput vrtoglavice, sedacije i mučnine.

  • Izgleda da tajna zdravijeg i mlađeg srca leži u vagusnom živcu. Naime, nova studija je pokazala da je očuvanje bilateralne srčane vagusne inervacije faktor protiv starenja srca. Posebno se desni srčani vagusni živac pojavljuje kao pravi čuvar zdravlja kardiomiocita, pomažući u očuvanju dugovječnosti srca neovisno o otkucajima srca.

  • Istraživanje koje je trajalo 10 godina otkrilo je da starije žene koje piju čaj imaju nešto jače kosti od svojih vršnjakinja koje konzumiraju kavu. Valja istaknuti, da čak i mala poboljšanja gustoće kostiju mogu smanjiti rizik od prijeloma kostiju.
