Monsanto is not your average Pesticide Manufacturer Glyphosate is a derivative of Agent Orange used in Vietnam to Defoliate the country and caused a lot of problems there other than defoliation.
Because of UKs lax laws and collusion of our politicians Monsanto dumped Agent Orange and other Horrors in quarries in Wales!!, Worldwide Monsanto is synonymous with not giving a f$$$ for Organic life of any kind.
So much so that they have merged/bought out with Bayer perhaps because Monsanto is hated by people who read a little.
Lots and lots on the internet about this, even from scientist who worked for the UN.
