EVIDENCE INDICATING THAT GLYPHOSATE-BASED HERBICIDES ARE NOT SAFE

In this list, most of the scientific papers cited have been published in peer-reviewed journals. Where possible, online links to the articles are given. Almost all the articles carry numerous references to previous scientific research.

Because there has been controversy over the safety or otherwise of glyphosate, there have been calls for more rigorous research, such as: Landrigan, P.J., Belpoggi, F. 2018. The need for independent research on the health-effects of glyphosate-based herbicides. Environmental Health 17: 51. 17 references.

In response to this need, the independently funded Ramazzini Institute initiated The Global Glyphosate Study in 2016, producing their first peer-reviewed papers from their pilot studies in 2018, which showed adverse effects from glyphosate at previously accepted 'safe doses'..

EVIDENCE FOR GLYPHOSATE SAFETY

?

Great doubts have been cast on the integrity of scientists and others who write in support of Glyphosate. As the agro-chemical business yields huge profits worldwide, there is much at stake. it is not surprising if the companies are prepared to pay for support, nor that some people of iinfluence may accept payment in return for their backing.

EPA Reregistration Decision: Glyphosate. EPA 738-R-93-014. September 1993, page 2. Bibliography: 281 entries, comprising 7 published papers, 228 unpublished papers submitted by Monsanto, 38 unpublished papers from other sources, 4 letters and 4 official statements / documents. When glyphosate came up for review by the United States Environmental Protection Agency in 2009-2010, "the Agency required the pesticide registrants to conduct additional studies to support updated human health and ecological risk assessments". Not suršrisingly, the onclusion remained that glyphosate use was 'safe'. 

In 2017 a campaign titled 'Stop Glyphosate' was launched as a European Citizens' Initiative petition titled 'Ban glyphosate and protect people and the environment from toxic pesticides'. In less than six months the petition garnered well over the 1 million signatures needed for consideration by the European Commission. However, the request for a ban was rejected out of hand.

On October 13th 2021, an open letter signed by 41 concerned civil society groups, including Eco Hvar, was sent to the EU Commission urging the Commission to stop using unreliable industry studies in the renewal assessment procedure for glyphosate.

Despite extensive research, I have not found any convincing independent scientific evidence for Glyphosate's safety. After all, how can any poison be safe? The slightest doubt should be enough to put a stop to its use, in accordance with the Precautionary Principle. If any reader comes across genuinely independent scientific papers published in peer-reviewed journals which put forward a reasoned case for the safe use of Glyphosate in the environment, we will consider adding them to this list of references.

  • Not a single waterway in England or Northern Ireland in good overall health, according to Rivers Trust

    The rivers of Britain and Ireland are in a desperate state from the impact of pollution, with not a single waterway in England or Northern Ireland listed as being in good overall health, a report said on Monday.

    The Rivers Trust annual State of Our Rivers report reveals that the impact of pollution from treated and untreated sewage and agricultural and industrial runoff means rivers are in a worse condition than ever.

  • Belgian capital blocked by 900 tractors amid protests throughout bloc demanding policy changes

    Farmers have clashed violently with police in the European quarter of Brussels, spraying officers with liquid manure and setting fire to mounds of tyres, while the EU’s agriculture ministers met to discuss the crisis in their sector.

    As farmers also protested in Madrid and on the Polish-German border, at least 900 tractors jammed streets in the centre of the Belgian capital, police said, with protesters throwing bottles and eggs and setting off fireworks while riot police fired water cannon.

  • Population has spread from small area of East Anglia to become established in Cambridgeshire, Kent and Herefordshire

    A rare dragonfly is no longer considered endangered after spreading its wings across England, but conservationists have said its wetland habitat is still at risk from climate breakdown.

    The Norfolk hawker, known for its bright green eyes and golden body, went extinct from the Cambridgeshire Fens in 1893 and became confined to east Norfolk and east Suffolk. It is thought this was caused by the draining of its preferred habitat of ponds and marshes for agriculture over the centuries. It has since been almost entirely restricted to the Norfolk Broads.

  • When it comes to reducing your clothes shopping’s carbon footprint, it might be tempting to abandon ecommerce for bricks-and-mortar retail. But the solution is not so simple

    Packages arrive at my house more than I’d like to admit. Whether they contain cosmetics, swimwear, T-shirts or socks, the sight of a brown cardboard box makes me feel two things: excitement for the new thing and guilt over its environmental impacts.

    Often the packaging feels excessive: boxes inside bigger boxes, things wrapped in bubble wrap or corrugated cardboard. And while compostable satchels are becoming more common, they’re not perfect solutions.

  • Warm spell in northern and central areas will make way for icy blast this week

    A sharp swing in temperatures has been forecast across northern and central parts of the US this week, with potentially record-breaking warm weather giving way to a cold front.

    Wisconsin is likely to challenge its all-time February high on Tuesday with a forecast of 17C (63F) – 0.5C above the record set at Stevens Point in 2000. The warm spell is likely to be short lived, however. On Tuesday evening a broad area of low pressure will bring heavy rain before a surge of cold air turns rain into snow as the temperature dips to zero.

  • Biodiversity campaigner Isabella Tree says wild areas work ‘hand in glove’ with food production as her Sussex estate boasts return of endangered species

    The Knepp estate in West Sussex is home to the first white stork born in the wild in Britain for over 600 years. It’s a place where endangered bats, turtle doves and nightingales are thriving, where “officially extinct” large tortoiseshell butterflies are breeding and where tens of thousands of people visit each year to experience “a story of hope” about the resilience of nature in the face of the global climate emergency.

    There have been many exciting changes at Knepp since 2018, when Isabella Tree wrote Wilding, her award-winning book about rewilding an unprofitable 3,500-acre arable and dairy farm. Now she has written a captivating illustrated book, Wilding: How to Bring Wildlife Back – An Illustrated Guide,updating her readers about extraordinary developments at Knepp and offering practical advice about rewilding their own spaces, however small.

  • Caistor St Edmund, Norfolk: As breeding season begins in the unseasonably mild weather, I’m transfixed by a local find – a meteorite

    I am holding a meteorite in my hand when something plummets to the ground just a couple of metres from my feet. I step back, trying to puzzle out what it is. At first, it’s just a brown, writhing shape, but then it fragments into three birds – house sparrows. One pings off into the sky, leaving a female pinned down by a male.

    Courtship often begins with a bobbing display dance from the male, but it can turn into a rough and tumble chase like this, sometimes with several males pursuing one female. This might be followed by mating. Seconds later, they both fly up from the ground and vanish out of sight.

  • It’s easy to understand why ambitious reforestation campaigns capture public attention. Earth’s forests are absolutely vital to staving off a climate crisis and protecting nature. But what about grasslands?

  • It’s a simple formula: More women in science equals more impactful and innovative science.

    Studies have found that scientific teams made up of women and men produce better research. Yet, of course, a persistent gender gap remains. Women make up about a third of the workforce in science, technology, engineering and math. And while there has been some progress in recent decades, it’s uneven. If current trends hold, it could take more than a century for women to be equally represented in fields like physics, math and engineering.

    For International Day of Women and Girls in Science, we are highlighting some of the women who power the science behind Conservation International’s work — changing conservation practices and informing critical policy decisions. Here, they share their passion for protecting nature — and their advice for the next generation of women scientists.
