The glyphosate thing was IARC (Int.Agency for Cancer Research) deeming that it was probably cancer causing; IIRC there's evidence suggesting that the US EPA had been corrupted in order to pass glyphosate for use. The FAO (Food and Agriculture Organization of the United Nations) and WHO have reportedly since determined that it is "safe" [enough] for human consumption and the ECHA (Euro. Chem. Agency) have determined that a ban is not required.

Pulling glyphosate would be devastating. But keeping it if it's causing widespread cancer would be continuing to ruin lives too. The Tories controlling the UK would IMO be more likely to let the proles die and support the farmers (who historically have a Tory preference). I prefer the EU's scientific and cautionary stance to the "will it cause loss of profit for shareholders" stance that we're going to be seeing much more of.
