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.

When Glyphosate came up for review by the United States Environmental Protection Agency, no scientific papers from peer-reviewed journals were included in the review document. The few published papers listed in the bibliography dealt largely with laboratory protocols. Otherwise the vast majority of the 'supporting evidence' consisted of unpublished papers sponsored by the agro-chemical companies who were seeking reregistration of the product.

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 Bibliography: 281 entries, comprising 7 published papers, 228 unpublished papers submitted by Monsanto, 38 unpublished papers from other sources, 4 letters and 4 official statements / documents.

Despite extensive research, I have not found any convincing 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.

    The number of meat and poultry products recalled in the US for potentially life-threatening health hazards has nearly doubled since 2013, according to a report by a consumer watchdog group.

    The US Department of Agriculture logged 97 meat recalls for serious health hazards in 2018, ranging from 12 million pounds of raw beef that made close to 250 people ill withsalmonella to the withdrawal of 174,000 pounds of chicken wraps for possible contamination with listeria.

  • Alaskans have been enjoying free, organic meat for the past 50 years. Should other places stop turning their noses up?

    My mother texts me four photos of a dead moose the week I leave Alaska. It is freshly hit. The pebbled pink brains fanning across the pavement have not yet grayed in the brisk autumn air. The animal will not go to waste. For the past 50 years, Alaska has been the only state where virtually every piece of large roadkill is eaten.

    Every year, between 600 and 800 moose are killed in Alaska by cars, leaving up to 250,000lb of organic, free-range meat on the road. State troopers who respond to these collisions keep a list of charities and families who have agreed to drive to the scene of an accident at any time, in any weather, to haul away and butcher the body.

  • As Hitachi and Toshiba abandon plans for new British nuclear reactors, Damian Carrington assesses the merits of the technology

    All sources of electricity face the same trilemma in the 21st century: carbon emissions, continuity of supply and cost. The UK government has placed a big bet on nuclear power, but reactors meet only two of the three challenges. Nuclear power is low carbon and a secure source of electricity – but it is hugely expensive.

    In the era of climate change, generating power without belching out carbon emissions is vital. While building nuclear plants and fuelling them requires concrete, transport and so on, the overall emissions are similar to windand solar power. All produce far less carbon than coal or gas-powered stations.

  • A complete overhaul of what we eat may be the only way to meet the needs of a planet in crisis. So what’s on – and off – the menu?

    The world faces many challenges over the coming decades, but one of the most significant will be how to feed its expanding global population. By 2050, there will be about 10 billion of us, and how to feed us all, healthily and from sustainable food sources, is something that is already being looked at. The Norway-based thinktank Eat and the British journal the Lancet have teamed up to commission an in-depth, worldwide study, which launches at 35 different locations around the world today, into what it would take to solve this problem – and the ambition is huge.

    The commissioners lay out important caveats. Their solution is contingent on global efforts to stabilise population growth, the achievement of the goals laid out in the Paris Agreement on climate change and stemming worldwide changes in land use, among other things. But they are clear that it depends on far more than just these basic requirements. The initial report presents a flexible daily diet for all food groups based on the best health science, which also limits the impact of food production on the planet.

  • Paris agreement for the sea recommended as rates of plastic pollution to skyrocket

    A new global agreement to protect the seas should be a priority for the government to stop our seas becoming a “sewer”, according to a cross-party group of MPs.

    Plastic pollution is set to treble in the next decade, the environmental audit committee warned, while overfishing is denuding vital marine habitats of fish, and climate change is causing harmful warming of the oceans as well as deoxygenation and acidification.

  • Scientist Brad Lister returned to Puerto Rican rainforest after 35 years to find 98% of ground insects had vanished

    “We knew that something was amiss in the first couple days,” said Brad Lister. “We were driving into the forest and at the same time both Andres and I said: ‘Where are all the birds?’ There was nothing.”

    His return to the Luquillo rainforest in Puerto Rico after 35 years was to reveal an appalling discovery. The insect population that once provided plentiful food for birds throughout the mountainous national park had collapsed. On the ground, 98% had gone. Up in the leafy canopy, 80% had vanished. The most likely culprit by far is global warming.

  • Rising temperatures can be charted back to the late 1950s, and the last five years were the five hottest on record

    Last year was the hottest ever measured, continuing an upward trend that is a direct result of manmade greenhouse gas emissions.

    The key to the measurements is the oceans. Oceans absorb more than 90% of the heat that results from greenhouse gases, so if you want to measure global warming you really have to measure ocean warming.

  • Campaigners say it will cut pollution, but opponents claim it will hit poor people hardest

    “I’m just really glad the ULEZ is coming. Children’s lungs can’t wait,” says Jemima Hartshorn, a Brixton resident who helped set up campaign group Mums For Lungs.

  • The continent’s largest land mammal plays crucial role in spiritual lives of the tribes

    On 5,000 hectares of unploughed prairie in north-eastern Montana, hundreds of wild bison roam once again. But this herd is not in a national park or a protected sanctuary – they are on tribal lands. Belonging to the Assiniboine and Sioux tribes of Fort Peck Reservation, the 340 bison is the largest conservation herd in the ongoing bison restoration efforts by North America’s Indigenous people.

    The bison – or as Native Americans call them, buffalo – are not just “sustenance,” according to Leroy Little Bear, a professor at the University of Lethbridge and a leader in the bison restoration efforts with the Blood Tribe. The continent’s largest land mammal plays a major role in the spiritual and cultural lives of numerous Native American tribes, an “integrated relationship,” he said.

  • Prospects for species look dire as federal science body finds that only one of the country’s 16 populations is believed to be stable

    Half of Canada’s chinook salmon are endangered, with nearly all other populations in precarious decline, according to a new report, confirming fears that prospects for the species remain dire.

    The reportby the Committee on the Status of Endangered Wildlife in Canada concluded that eight of the country’s 16 populations are considered endangered, four are threatened, one is of special concern and the health of two remain unknown.
