Glyphosate, What You Need To Know


People have been asking a lot of questions about glyphosate, also commonly known as Roundup. The herbicide has a lengthy track record of being one of the safest and most effective tools used in agriculture – and that is why it has been targeted by activists. To help provide quality information, Global Farmer Network will assemble a webpage providing links to resources and relevant coverage – it will be a work-in-progress as we’ll continue to add some important material for the near future.

Glyphosate on Trial – McGill University, Office for Science and Society – By Joe Schwarcz, PhD (Aug 16, 2018)

“Even if glyphosate were an established carcinogen, which it is not, it would never be possible to conclude that it caused a specific individual’s non-Hodgkins lymphoma. This particular cancer has numerous risk factors that include alcohol intake, Helicobacter pylori infection, exposure to hepatitis virus, various autoimmune diseases and contact with lubricating oils, benzidine dyes, wood dust, pesticides and herbicides. Making a decision on an individual case comes down to a matter of opinion forged by blending ‘evidence’ with emotion. The problem is that ‘evidence’ is dependent on who is presenting it and to what extent the data has been cherry-picked.” – Link
